What the threads have in common is a kind of dreamlike, affectless prose that effectively nulls characterization — Anna's husband, we're asked to believe, is a mover and shaker in the music business, but nothing about his behavior adds credibility to this bare résumé.

Nulls Creek is a stream in Lincoln County in the U.S. state of Missouri. Nulls Creek has the name of Jacob Null, a pioneer settler.

Nulls on transmission lines are very sharp, in contrast to the peaks which are broad and flat. This makes the nulls easier to measure. An instrument in electronics for measuring the positions of nulls on a line is the slotted line. This instrument can also be used to measure VSWR.

Some SQL products do not index keys containing NULLs. For instance, PostgreSQL versions prior to 8.3 did not, with the documentation for a B-tree index stating that In cases where the index enforces uniqueness, NULLs are excluded from the index and uniqueness is not enforced between NULLs. Again, quoting from the PostgreSQL documentation: This is consistent with the SQL:2003-defined behavior of scalar Null comparisons. Another method of indexing Nulls involves handling them as not distinct in accordance with the SQL:2003-defined behavior.

Primary Key constraint # A primary key cannot allow null (a primary key cannot be defined on columns that allow nulls). # Each table cannot have more than one primary key. # On some RDBMS a primary key generates a clustered index by default. Unique constraint # A unique constraint can be defined on columns that allow nulls, in which case rows that include nulls may not actually be unique across the set of columns defined by the constraint.

With the SQL:2003 extension T611, "Elementary OLAP operations", nulls can be sorted before or after all data values by using the `NULLS FIRST` or `NULLS LAST` clauses of the `ORDER BY` list, respectively. Not all DBMS vendors implement this functionality, however. Vendors who do not implement this functionality may specify different treatments for Null sorting in the DBMS. Structure `ORDER BY ... DESC` will order in descending order, otherwise ascending order is used.
|
|
For example, Microsoft SQL Server documentation states the following: Both of these indexing strategies are consistent with the SQL:2003-defined behavior of Nulls. Because indexing methodologies are not explicitly defined by the SQL:2003 standard, indexing strategies for Nulls are left entirely to the vendors to design and implement.

SQL defines two functions to explicitly handle Nulls: `NULLIF` and `COALESCE`. Both functions are abbreviations for searched `CASE` expressions.

In physics a null is a point in a field where the field quantity is zero as the result of two or more opposing quantities completely cancelling each other. The field may be scalar, vector or tensor in nature. Common situations where nulls arise are in the polar patterns of microphones and antennae, and nulls caused by reflections of waves.
|
|
Dipole antenna polar pattern A common, and basic, radio antenna is the dipole. This has a figure-of-eight polar pattern with two nulls on opposite sides. Highly directional antennae, such as the Yagi have polar patterns very similar to highly directional microphones and for similar reasons. That is, they have multiple small lobes off the main direction with nulls between them.

Performance advantages with a Storage Index are most evident when the indexed column contains many nulls. Massive performance advantages are gained when scanning across sparse data.

The following example table with a check constraint will prohibit any integer values from being inserted into column i, but will allow Null to be inserted since the result of the check will always evaluate to Unknown for Nulls. CREATE TABLE t ( i INTEGER, CONSTRAINT ck_i CHECK ( i < 0 AND i = 0 AND i > 0 ) ); Because of the change in designated values relative to the WHERE clause, from a logic perspective the law of excluded middle is a tautology for CHECK constraints, meaning CHECK (p OR NOT p) always succeeds. Furthermore, assuming Nulls are to be interpreted as existing but unknown values, some pathological CHECKs like the one above allow insertion of Nulls that could never be replaced by any non-null value. In order to constrain a column to reject Nulls, the `NOT NULL` constraint can be applied, as shown in the example below.

In transmitting antennas designed to provide broad coverage nulls can be a problem, preventing reception in a given area. Null fill in the vertical plane is used to prevent this. On the other hand, nulls can also be used to advantage. In a radio receiver the receiver's antenna can be adjusted so the direction of the interference source is located in a null of the antenna, to minimize reception of interference.

Open ended tubes must have zero air pressure change at the end of the tube so this point is a pressure null. Closed tubes must have zero air velocity at the end of the tube so this point is a velocity null. There may further nulls along the tube depending on the vibration mode that has been set up by the instrument player. Higher modes have more nulls.

To measure the bearing of a transmitter, the loop is spun about its vertical axis until the signal drops to zero, or nulls, which is a much sharper signal that the maximum.

If DLX5 is disrupted in conjunction with DLX6, bone, inner ear, and severe craniofacial defects are prevalent. Research utilizing Dlx5/6-nulls suggests that these genes have both unique and redundant functions.

Nulls are used in electrical science to make many measurements. A frequently encountered technique is to adjust the voltage in one branch of a circuit until it nulls out a voltage in another branch. Commonly, a bridge circuit is used for this purpose. There are many varieties of measurement bridge, the most well known of these being the Wheatstone bridge used to accurately measure the resistance of an unknown component against a calibrated variable resistance by comparing the voltages across each.

The long wavelengths used in these early radars strongly interacted with the ground, causing the beams to be reflected forward as opposed to absorbed or scattered. These reflected signals sometimes reached the targets and were returned to the receiver, along with the ones direct from the transmitter. Interference between the two caused nulls to appear in the reception pattern, which made it difficult to find the target. In practice, these nulls, especially in elevation, would move about when the antennas rotated to track a target.

E. F. Codd mentioned nulls as a method of representing missing data in the relational model in a 1975 paper in the FDT Bulletin of ACM-SIGMOD. Codd's paper that is most commonly cited in relation with the semantics of Null (as adopted in SQL) is his 1979 paper in the ACM Transactions on Database Systems, in which he also introduced his Relational Model/Tasmania, although much of the other proposals from the latter paper have remained obscure. Section 2.3 of his 1979 paper details the semantics of Null propagation in arithmetic operations as well as comparisons employing a ternary (three-valued) logic when comparing to nulls; it also details the treatment of Nulls on other set operations (the latter issue still controversial today). In database theory circles, the original proposal of Codd (1975, 1979) is now referred to as "Codd tables".

It is possible to put UNIQUE constraints on nullable columns but the SQL standard states that the constraint does not guarantee uniqueness of nullable columns (uniqueness is not enforced for rows where any of the columns contains a null). According to the SQLSummary of ANSI/ISO/IEC SQL standard a unique constraint does not enforce uniqueness in the presence of nulls and can therefore contain several rows with identical combinations of nulls and non-null values — however not all RDBMS implement this feature according to the SQL standard.
|
|
Nulls have also been used intentionally to prevent an antenna from broadcasting to a certain area. For example, CIII-DT-22, a repeater of Toronto-based Global TV station CIII-DT in Wheatley has a null towards Windsor to protect broadcast rights of American stations in the bordering Detroit area. Radio direction finding (RDF) receivers use special antennas with very narrow, sharp nulls to find the location of transmitters. The antenna is rotated until the received signal is minimum; at that point the antenna's null is pointed along the bearing line to the transmitter.
|
|
Another point of conflict concerning Nulls is that they violate the closed-world assumption model of relational databases by introducing an open-world assumption into it. The closed world assumption, as it pertains to databases, states that "Everything stated by the database, either explicitly or implicitly, is true; everything else is false." This view assumes that the knowledge of the world stored within a database is complete. Nulls, however, operate under the open world assumption, in which some items stored in the database are considered unknown, making the database's stored knowledge of the world incomplete.

Some models use antenna diversity (two antennas) to prevent nulls from interrupting transmission as the performer moves around. A few low cost (or specialist) models use infrared light, although these require a direct line of sight between microphone and receiver.

Following the chess analogy, the route taken might be the knight's move. Or some other path can be agreed upon, such as a reverse spiral, together with a specific number of nulls to pad the start and end of a message.

Once a link starts, it continuously exchanges characters. These are NULLs if there is no data to exchange. This tests the link, and assures that the parity bits are sent quickly to finish messages. Each slice has its own start-up sequence.

As a null, he was adopted as Nibbles by Megabyte, who apparently knew his true identity as he once referred to him as "Father." :In Season 4, Hexadecimal's powers over nulls allowed him to regain his sentient mind and mold with other nulls to form a body. While catching up with his family, the young Enzo was found to have adapted to his dad's transformation quite well ("Dad's a null monster now, it's so cool!."), though Phong informed Welman of Matrix also being his son, there was no apparent interaction between the two during the series except for Matrix being glad his father had returned.

|
In SQL, the intermediate value is intended to be interpreted as UNKNOWN. Explicit comparisons with NULL, including that of another NULL yields UNKNOWN. However this choice of semantics is abandoned for some set operations, e.g. UNION or INTERSECT, where NULLs are treated as equal with each other.

Most shellcodes are written without the use of null bytes because they are intended to be injected into a target process through null-terminated strings. When a null-terminated string is copied, it will be copied up to and including the first null but subsequent bytes of the shellcode will not be processed. When shellcode that contains nulls is injected in this way, only part of the shellcode would be injected, making it incapable of running successfully. To produce null-free shellcode from shellcode that contains null bytes, one can substitute machine instructions that contain zeroes with instructions that have the same effect but are free of nulls. For example, on the IA-32 architecture one could replace this instruction: B8 01000000 MOV EAX,1 // Set the register EAX to 0x000000001 which contains zeroes as part of the literal (`1` expands to `0x00000001`) with these instructions: 33C0 XOR EAX,EAX // Set the register EAX to 0x000000000 40 INC EAX // Increase EAX to 0x00000001 which have the same effect but take fewer bytes to encode and are free of nulls.

In order to make him happy, she used her powers to drive out Daemon's forces; this weakened her powers enough for the viral scan, which had remained in her Icon, to start again, and she covered herself with Nulls to stop it. When the Null-cocoon fled as a Game landed on her, she became a normal, powerless Sprite; wearing a new costume of white lace and gold instead of black leather and red, with normal-looking eyes and black hair. Strangely enough, Hex retained her control over Nulls, even though the rest of her powers had been stripped away. Upon revealing her origin to Dot, she began referring to her as "Sis".

Yagi-Uda antenna polar pattern showing pattern of alternating lobes and nulls In radio electronics, a null is a direction in an antenna's radiation pattern where the antenna radiates almost no radio waves, so the far field signal strength is a local minimum. Nulls occur because different parts of an antenna radiate radio waves of different phase. In directions at which the antenna radiates equal amplitude radio waves of opposite phase, the radio waves cancel, resulting in little or no radio power being radiated in that direction. In other directions the radio waves from different parts of the antenna are in phase and reinforce, resulting in a maximum signal strength in the radiation pattern, called a lobe.

Its 300 ft. antenna had a horizontal 5-wire cage design, had the required 400 amp electrical service, and its design was directional with nulls produced in certain directions. Reception reports came in from all over the country and beyond. Only 2 official broadcasts were made: December 25 & December 31, 1996.

Past TACANs have relied on high output power (up to 10,000 watts) to ensure good signal in space to overcome nulls present in antenna design and to provide their required 200 mile range. With the advancement of technology, antenna design has improved with higher gain antennas, much shallower nulls, and lighter construction. Now it's feasible to have a 200 nmi range with a 400 watt TACAN DME transmitter, making the TACAN package much smaller, more portable and more reliable (a decrease in power also reduces heat, which lengthens the life of electronics). On the first Space Shuttle flight, Capcom Joseph P. Allen reported up to the crew that their TACANs had locked onto the Channel 111 signals at St. Petersburg, FL at a range of 250 miles.

Relational completeness clearly does not imply that any interesting database query can be expressed in relationally complete languages. Well-known examples of inexpressible queries include simple aggregations (counting tuples, or summing up values occurring in tuples, which are operations expressible in SQL but not in relational algebra) and computing the transitive closure of a graph given by its binary edge relation (see also expressive power). Codd's theorem also doesn't consider SQL nulls and the three-valued logic they entail; the logical treatment of nulls remains mired in controversy.For recent work extending Codd's theorem in this direction see Additionally, SQL allows duplicate rows (has multiset semantics.) Nevertheless, relational completeness constitutes an important yardstick by which the expressive power of query languages can be compared.

Given the importance of the C957T and TaqIA polymorphisms for the diagnosis and treatment of psychological disorder, a rapid screening protocol for these genes has been developed. Since the DRD2 1101A allele nulls the effects of the 957T allele, screens for the 957C allele which ignore the 1101A allele can sometimes lead to false negatives.

The signal is captured at an effective sample rate of 10 terasamples per second. In a conventional analog optical link, dispersion causes the upper and lower modulation sidebands, foptical ± felectrical, to slip in relative phase. At certain frequencies, their beats with the optical carrier interfere destructively, creating nulls in the frequency response of the system.

Computer Age Statistical Inference. Cambridge University Press, 2016. Under a Bayesian framework, the large-scale studies allow the null distribution to be put into a probabilistic context with its non-null counterparts. When sample size n is large, like over 10,000, the empirical nulls utilize a study's own data to estimate an appropriate null distribution.

This is common in military communications. In that case, and if the transmission channel is not fully loaded, there is a good likelihood that one of the ciphertext streams will be just nulls. The NSA goes to great lengths to prevent keys from being used twice. 1960s-era encryption systems often included a punched card reader for loading keys.

In a regular columnar transposition cipher, any spare spaces are filled with nulls; in an irregular columnar transposition cipher, the spaces are left blank. Finally, the message is read off in columns, in the order specified by the keyword. For example, suppose we use the keyword `ZEBRAS` and the message `WE ARE DISCOVERED. FLEE AT ONCE`.

Oracle's dialect of SQL provides a built-in function `DECODE` which can be used instead of the simple CASE expressions and considers two nulls equal. SELECT DECODE(i, NULL, 'Null Result', 0, 'Zero', 1, 'One') FROM t; Finally, all these constructs return a NULL if no match is found; they have a default `ELSE NULL` clause.

GT.M has only two data types - canonical numbers and strings. A string is any arbitrary sequence of bytes (including nulls). A string such as `"42"` is a canonical number. Data typing is dynamic and conversion between the two types is performed on the fly as needed: `1+"42"` yields the result `43`, and the first character of `43` is `4`.

104 To counter frequency analysis, some number sets were "nulls" meant to be ignored by the intended recipient. Others were traps, including a codegroup that meant to ignore the previous codegroup. As a nomenclator cipher, the Great Cipher replaced the names of key generals such as Auguste de Marmont, references to les ennemis, and other sensitive terms with homophonic substitutions.Kahn 2005, p.

A check constraint is a type of integrity constraint in SQL which specifies a requirement that must be met by each row in a database table. The constraint must be a predicate. It can refer to a single column, or multiple columns of the table. The result of the predicate can be either `TRUE`, `FALSE`, or `UNKNOWN`, depending on the presence of NULLs.

Due to her power and insanity, her fun nearly always led to Mainframe crashing. She even once nearly caused it unwittingly, when a Web Creature emerged from her mirror and possessed her. All of the nulls sensed this danger and covered her completely. The giant "Nullzilla" monster went on a rampage, as (according to Dot) the possessed-Hexadecimal was trying to escape.

Since the transmissions always use complete groups, "nulls" may have been used to pad out the text. Cryptosystems employed include transposition, dinome, and rotor-based ciphers and a one-part code. While these can be successfully tackled without use of a computer, solution is not easy. The practical exercise reinforces many basic principles, including ways to exploit having a collection of message traffic.
|
|
Standing waves also occur on electrical transmission lines. A line with a non-resistive termination will cause a reflection of the signal from the termination with the same amplitude as the incident wave. These waves will cancel periodically along the line causing nulls every half wavelength. The distance of the first null from the termination depends on the nature of the terminating impedance.

Simonetta has been described in the cryptological literature as an important cryptanalyst in consideration of his rules. His work is in reality a collection of hints for solving ciphers that were rather old-fashioned at that time. Contemporary cipher clerks were well equipped to defy the tricks he described. Nomenclators were in general use, combining small codebooks and large substitution tables with homophones and nulls.

The protagonists sometimes hunt special forms of illegals in the hope of collecting valuable metabugs. Illegals, originating from "the other side", sometimes become lost and isolated in the city and express a desire to return to their "homeland". Some humanoid illegals known as Nulls can whisk people away to "the other side" by inducing "dennō coil"—a comatose state where the victim is trapped in VR.

Small loop antennas have a small circumference compared to the operating wavelength. They may be used for transmission and reception, although antennas that are very small compared to the wavelength are very inefficient radiators, and so are only used for reception. An example is the ferrite (loopstick) antenna used in most AM broadcast radios. The radiation pattern of a small loop antenna has two sharp nulls in opposite directions.

Another ability he has shown is the ability to read memory from certain sprites, namely Phong (Infected). He also manages to steal Bob's exchanged Guardian code with Glitch. Megabyte has no sense of morality and consistently takes advantage of others to achieve his own ends. He also seems immune to the energy-draining effect of nulls (as he has been seen holding his pet null "Nibbles", whom he once called "Father").

Honduras National Congress has 128 members (diputados); they serve four-year terms. Honduras elects on national level a head of state - the president - and a legislature. The President of Honduras is elected for a four-year term by the people by a simple majority of valid votes (nulls and blanks excluded). The unicameral National Congress (Congreso Nacional) has 128 members (diputados), elected for four-year term by proportional representation to represent the country's various departments.

Small spherical "point-source" acoustic devices follow the known inverse square law, which predicts the loss of 6 decibels (dB) per doubling of distance from the source, solely due to geometric spreading.

Although WTVN only uses 5,000 watts of power during the day, the station can be heard as far away as Indianapolis, Fort Wayne, Detroit, and Cleveland. At night, the signal uses a directional antenna to protect stations operating on the same frequency, such as in KCSP in Kansas City; WTEL in Philadelphia; and WIOD in Miami. The extra power is radiated over central Columbus. However, outlying suburbs in the direction of the nulls will experience a degraded signal.

His cipher-breaking rules are applicable to dispatches with word divisions, without homophones, nulls or code words. He says nothing of polyalphabetic substitution or the existence of nomenclators. His notes were anticipated by Leon Battista Alberti in his theoretical, but more comprehensive, treatise De Cifris, which earned him the title of Father of Western Cryptology. It was only a century later that a scientific treatise entirely devoted to cryptanalysis was written by the French mathematician François Viète.

Ring laser gyroscope A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in the frequencies is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation. Interference between the counter-propagating beams, observed externally, results in motion of the standing wave pattern, and thus indicates rotation.

Joins evaluate using the same comparison rules as for WHERE clauses. Therefore, care must be taken when using nullable columns in SQL join criteria. In particular a table containing any nulls is not equal with a natural self-join of itself, meaning that whereas R \bowtie R = R is true for any relation R in relational algebra, a SQL self-join will exclude all rows having a Null anywhere.C.J. Date (2004), An introduction to database systems, 8th ed.

A solution to this problem was introduced by the UK in the late 1920s, and tested experimentally at the Orfordness Beacon. This system essentially reversed the RDF concept, placing the rotating antenna on the ground instead of the vehicle, spinning it slowly at 1 rpm (6 degrees a second). Any radio tuned to the station would hear the nulls as the antenna's pattern passed them. The trick, however, was knowing what angle the antenna was pointed at that instant.

In contrast Long Wavelength magnetic transmissions (below 1 MHz) is not blocked or reflected by steel so nulls do not occur. The loop antennas may be detuned by the steel, just like higher frequencies. But, unlike higher frequencies, magnetic loop antennas may be re- tuned with external capacitors, and, in many cases, circuits can be created that dynamically pick the optimal external capacitor for the antenna. Thus the de-tuning issue can vanish in a RuBee network.

Also the Servo Amplifiers, picking off the tiny Gyro signals and amplifying this to control the platform gimbal motors, have tight specifications. The actual integration of the accelerometer signal to a velocity signal is performed by an electronic amplifier which controls a velocity-motor which drives a capacitance tachometer. This cap-tach feedback provides the basic integrator signal since the speed of the cap-tach is proportional to acceleration input. The feedback nulls the acceleration input to stop the motor.

While leaving, Zero acquires a tape containing the Prison's security footage from the night of Fa Yuan's murder. The tape footage shows The Dragon storming the prison and interrogating Fa Yuan, who tells him about Leon von Alvensleben, the creator of Chronos. After finding the psychiatric office closed, Zero is directed to a slaughterhouse by an unknown caller. The slaughterhouse proves to be a front for a training facility for 'NULLs', Chronos-enhanced super soldiers used by New Mecca in the Cromag war.

Through common genetrapping mechanisms, homozygous MSulf2 mice were created to assess the in vivo phenotypic traits. Strain specific nonpenetrant lethality resulted (48% fewer than expected), pups were smaller, and some lung defects were observed, but MSulf2-/- were largely as healthy and viable as wild type litter mates. MSulf2 nulls indicate MSulf1 and MSulf2 may have overlapping functions in regulating sulfation patterns in HSPGs. Given that MSulf2 null mice did not present major abnormal phenotypes double MSulf1/2 knockouts were generated.

The transmitting location was on old Highway 18 just west of Mason City. Shortly thereafter, power was increased to five kilowatts and two flanking towers were added to produce a directional signal at night with deep nulls to the east and west. In 1998, the transmitter was moved to six miles south of Mason City with directional pattern both day and night to provide a better signal over Mason City. The revenue generated by KGLO radio provided for significant corporate expansion.

When the entire waveform moves in one direction it is said to be a traveling wave; by contrast, a pair of superimposed periodic waves traveling in opposite directions makes a standing wave. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero. The types of waves most commonly studied in classical physics are mechanical and electromagnetic. In a mechanical wave, stress and strain fields oscillate about a mechanical equilibrium.

Query Rewriting is a typically automatic transformation that takes a set of database tables views and/or queries, usually indices, often gathered data and query statistics, and other metadata, and yields a set of different queries, which produce the same results but execute with better performance (for example, faster, or with lower memory use). Query rewriting can be based on relational algebra or an extension thereof (e.g. multiset relational algebra with sorting, aggregation and three-valued predicates i.e. NULLs as in the case of SQL).

The attack is completely successful if the corresponding plaintexts can be deduced, or even better, the key. The ability to obtain any information at all about the underlying plaintext beyond what was pre-known to the attacker is still considered a success. For example, if an adversary is sending ciphertext continuously to maintain traffic-flow security, it would be very useful to be able to distinguish real messages from nulls. Even making an informed guess of the existence of real messages would facilitate traffic analysis.

However, the HZ list in France remained legal. HZ candidates in Spain then campaigned for using the French HZ ballot in Spain, which was to be counted as a null vote. There were more than 98,000 null votes in the Basque Autonomous Country and more than 15,000 in Navarre. HZ leaders interpreted the high rate of null votes, which was 12% of the total, to mean that most of the nulls were for HZ, since in the previous European elections the null vote was less than 1%.

The SQL `INTERSECT` operator takes the results of two queries and returns only rows that appear in both result sets. For purposes of duplicate removal the `INTERSECT` operator does not distinguish between `NULLs`. The `INTERSECT` operator removes duplicate rows from the final result set. The `INTERSECT ALL` operator does not remove duplicate rows from the final result set, but if a row appears X times in the first query and Y times in the second, it will appear min(X, Y) times in the result set.

Early radio direction finding (RDF) solutions used highly directional antennas with sharp "nulls" in the reception pattern. The operator rotated the antenna looking for points where the signal either reached a maximum, or more commonly, suddenly disappeared or "nulled". A common RDF antenna design is the loop antenna, which is simply a loop of wire with a small gap in the circle, typically arranged to rotate around the vertical axis with the gap at the bottom. Some systems used dipole antennas instead of loops.

A common alternative to is to use a variable-width encoding, whereby a logical character may extend over multiple positions of the string. Variable-width strings may be encoded into literals verbatim, at the risk of confusing the compiler, or using numerical backslash escapes (e.g. for "é" in UTF-8). The UTF-8 encoding was specifically designed (under Plan 9) for compatibility with the standard library string functions; supporting features of the encoding include a lack of embedded nulls, no valid interpretations for subsequences, and trivial resynchronisation.

Generics are a facility of generic programming that were added to the Java programming language in 2004 within version J2SE 5.0. They were designed to extend Java's type system to allow "a type or method to operate on objects of various types while providing compile-time type safety".Java Programming Language The aspect compile-time type safety was not fully achieved, since it was shown in 2016 that it is not guaranteed in all cases.A ClassCastException can be thrown even in the absence of casts or nulls.

The Frontend is concerned with the dynamic derivation of user interfaces and the presentation thereof in either the Windows or Web thin client. Dataphor does not employ SQL as its primary database language since SQL purportedly violates important principles of the relational model. Dataphor's D4 language is based on the principles of Christopher J Date's and Hugh Darwen's Tutorial D, but with a Pascal-like imperative syntax. Though Dataphor espouses to be truly relational, it does incorporate the concept of NULLs as found in SQL, which many claim to be contraindicated by the Relational Model.
|
|
NULLs and the matter of managing missing information, however, continue to be debated. In addition to the data management focus of the Dataphor Server, Dataphor includes tools which allow the presentation of user interfaces through Windows and Web "thin" clients. Dataphor takes advantage of the relational inference capabilities of the Dataphor compiler in order to allow complete GUI forms to be derived directly from the data model. The unique aspect of Dataphor's user interface "derivation" is that it may be based on any relational expression (query) rather than merely base tables.

Earlier systems used a mechanically rotated antenna (or solenoid) and an operator listening for peaks or nulls in the signal, which took considerable time to determine, often on the order of a minute or more. HF/DF's display made the same measurement essentially instantaneously, which allowed it to catch fleeting signals, such as those from the U-boat fleet. The system was initially developed by Robert Watson-Watt starting in 1926, as a system for locating lightning. Its role in intelligence was not developed until the late 1930s.

Normally the radio operator would first use conventional radio tuners to find the signal in question, either using the DF antenna(s) or on a separate non-directional antenna. Once tuned, the operator rotated the antennas or goniometer looking for peaks or nulls in the signal. Although the rough location could be found by spinning the control rapidly, for more accurate measurements the operator had to "hunt" with increasingly small movements. With periodic signals like Morse code, or signals on the fringe of reception, this was a difficult process.

In electrical engineering degrees of freedom is often used to describe the number of directions in which a phased array antenna can form either beams or nulls. It is equal to one less than the number of elements contained in the array, as one element is used as a reference against which either constructive or destructive interference may be applied using each of the remaining antenna elements. Radar practice and communication link practice, with beam steering being more prevalent for radar applications and null steering being more prevalent for interference suppression in communication links.

While there, Burgess and the humans form close bonds with the Felines and with Doe, the Caprine female. Colene persuades the predatory dragons of the world to prey on rats instead of nulls, and Darius agrees to give Ddwng the Chip in return for the continued safety of Chains and its inhabitants. Once on the Virtual Mode, the party attempts to evade the pursuit of the four unknown anchor persons. Colene regains mental contact with Seqiro, but the mind predator soon finds her, and the group must return to Earth.

Ddwng's anchor mode, pronounced , is a super-science reality in which psionic power, including emotional transfer, is possible in limited form, but sympathetic magic is non-operational. The people of the primary planet have created technology which is able to bypass some of the laws of physics, such as the speed of light, making FTL travel possible. They have refined the science of genetic engineering; people suffer from no genetic diseases and few effects of aging. They are also able to manufacture android-like beings called "nulls" from leftover genetic material.

Unfortunately, there is no standard bucket size (D86 width, Gaussian beam width, Airy disk nulls, etc.) or bucket shape (circular, rectangular, etc.) and there is no standard beam to compare for the Strehl ratio. Therefore, these definitions must always be specified before a number is given and it presents much difficulty when trying to compare lasers. There is also no simple conversion between M2, power-in-the-bucket, and Strehl ratio. The Strehl ratio, for example, has been defined as the ratio of the peak focal intensities in the aberrated and ideal point spread functions.

Radiation pattern of a 3λ/2 monopole antenna. Although the radiation of an omnidirectional antenna is symmetrical in azimuthal directions, it may vary in a complicated way with elevation angle, having lobes and nulls at different angles. Common types of low-gain omnidirectional antennas are the whip antenna, "Rubber Ducky" antenna, ground plane antenna, vertically oriented dipole antenna, discone antenna, mast radiator, horizontal loop antenna (sometimes known colloquially as a 'circular aerial' because of the shape) and the halo antenna. Higher-gain omnidirectional antennas can also be built.

This antenna is small enough that it is usually enclosed inside the radio case. In addition to their use in AM radios, ferrite antennas are also used in portable radio direction finder (RDF) receivers. The ferrite rod antenna has a dipole reception pattern with sharp nulls along the axis of the rod, so that reception is at its best when the rod is at right angles to the transmitter, but fades to nothing when the rod points exactly at the transmitter. Other types of loop antennas and random wire antennas are also used.

The four letters in the movable disk facing the four numbered cells of the outer ring will not have, so to speak, any meaning by themselves and may be inserted as nulls within the text. However, if used in groups or repeated, they will be of great advantage, as I will explain later on. ::Chapter XV. We can also choose the index letter among the capital letters and agree between us which of them will be the index. Let us suppose we chose the letter B as an index.

Although some database systems allow the specification of an `ORDER BY` clause in subselects or view definitions, the presence there has no effect. A view is a logical relational table, and the relational model mandates that a table is a set of rows, implying no sort order whatsoever. The only exception are constructs like `ORDER BY ORDER OF ...` (not standardized in SQL:2003) which allow the propagation of sort criteria through nested subselects. The SQL standard's core functionality does not explicitly define a default sort order for Nulls.

One might wish to measure the harmonic content of a musical note from a particular instrument or the harmonic distortion of an amplifier at a given frequency. Referring again to Figure 2, we can observe that there is no leakage at a discrete set of harmonically-related frequencies sampled by the DFT. (The spectral nulls are actually zero-crossings, which cannot be shown on a logarithmic scale such as this.) This property is unique to the rectangular window, and it must be appropriately configured for the signal frequency, as described above.

Therefore, the radiation plot of most antennas shows a pattern of maxima called "lobes" at various angles, separated by "nulls" at which the radiation goes to zero. The larger the antenna is compared to a wavelength, the more lobes there will be. A rectangular radiation plot, an alternative presentation method to a polar plot. In a directional antenna in which the objective is to emit the radio waves in one particular direction, the antenna is designed to radiate most of its power in the lobe directed in the desired direction.

In a regular columnar transposition, we write this into the grid as follows: 6 3 2 4 1 5 W E A R E D I S C O V E R E D F L E E A T O N C E Q K J E U providing five nulls (`QKJEU`), these letters can be randomly selected as they just fill out the incomplete columns and are not part of the message. The ciphertext is then read off as: EVLNE ACDTK ESEAQ ROFOJ DEECU WIREE In the irregular case, the columns are not completed by nulls: 6 3 2 4 1 5 W E A R E D I S C O V E R E D F L E E A T O N C E This results in the following ciphertext: EVLNA CDTES EAROF ODEEC WIREE To decipher it, the recipient has to work out the column lengths by dividing the message length by the key length. Then he can write the message out in columns again, then re-order the columns by reforming the key word. In a variation, the message is blocked into segments that are the key length long and to each segment the same permutation (given by the key) is applied.

These antennas have a bidirectional receiving pattern, with two peak directions 180° apart from one another and two null directions 180° apart from one another. The peak directions are 90° offset from the null directions. A small vertical antenna element can be combined with the loop or ferrite rod antenna to change the receiving pattern to a cardioid shape, but the resulting null in the cardioid is not as sensitive as the nulls in the bidirectional receiving pattern. A switch is often used to allow the competitor to select the bidirectional or cardioid patterns at any moment.

Every location has distinct and subtle sounds created by its environment. These sound sources can include wildlife, wind, music, rain, running water, thunder, rustling leaves, distant traffic, aircraft and machinery noise, the sound of distant human movement and speech, creaks from thermal contraction, air conditioning and plumbing noises, fan and motor noises, and harmonics of mains power. Reverberation will further distort these already faint sounds, often beyond recognition, by introducing complex patterns of peaks and nulls in their frequency spectrum, and blurring their temporal characteristics. Finally, sound absorption can cause high frequencies to be rolled off, dulling the sound further.

The SQL `EXCEPT` operator takes the distinct rows of one query and returns the rows that do not appear in a second result set. For purposes of row elimination and duplicate removal, the `EXCEPT` operator does not distinguish between `NULLs`. The `EXCEPT ALL` operator does not remove duplicates, but if a row appears X times in the first query and Y times in the second, it will appear max(X - Y, 0) times in the result set. Notably, the Oracle platform provides a `MINUS` operator which is functionally equivalent to the SQL standard `EXCEPT DISTINCT` operator .

The radiation pattern of most antennas shows a pattern of "lobes" at various angles, directions where the radiated signal strength reaches a maximum, separated by "nulls", angles at which the radiated signal strength falls to zero. This can be viewed as the diffraction pattern of the antenna. In a directional antenna in which the objective is to emit the radio waves in one direction, the lobe in that direction is designed to have a larger field strength than the others; this is the "main lobe". The other lobes are called "side lobes", and usually represent unwanted radiation in undesired directions.

The SZA is not a single telescope, but an array of 8 telescopes operating together as an interferometer. An interferometer does not detect light in quite the same way as an ordinary telescope, by measuring the total power collected by a single dish; instead, it looks at differences between the light falling on pairs of telescopes. Like water waves, light waves can interfere with each other, producing a complex pattern of intensity enhancements where the waves constructively interfere, and nulls where they destructively interfere. As light from a source washes over the array, an interferometer detects this interference pattern — hence the name.

For practical systems the first null is at tens of GHz, which is sufficient for handling most electrical signals of interest. Although it may seem that the dispersion penalty places a fundamental limit on the impulse response (or the bandwidth) of the time- stretch system, it can be eliminated. The dispersion penalty vanishes with single-sideband modulation. Alternatively, one can use the modulator's secondary (inverse) output port to eliminate the dispersion penalty, in much the same way as two antennas can eliminate spatial nulls in wireless communication (hence the two antennas on top of a WiFi access point).

WNPN transmits using a Nautel GV15 transmitter with 10,187 watts transmitter power output (TPO) to make 7,000 watts effective radiated power (ERP). A Shively Labs 6016 four-panel antenna array is used; the antenna is fairly directional, with nulls to avoid prohibited interference to/from WQPH 89.3FM Shirley, Massachusetts to the north-northwest, and to WPKT 89.1FM Norwich, Connecticut to the west-southwest. An Omnia 9 FM/HD processor from The Telos Alliance is used to keep audio levels consistent. The station broadcasts in digital HD Radio although no multicast HD2 or HD3 channels are transmitted.

This is possible if the target has a bug which leaks information, e.g., if the attacker has access to /proc/(pid)/maps. There is an obscurity patch which NULLs out the values for the address ranges and inodes in every information source accessible from userland to close most of these holes; however, it is not currently included in PaX. The second and third classes of attacks are possible with a small probability if the attacker needs advance knowledge of address space layout, but cannot derive this knowledge without resorting to guessing or to a brute force search.

The Ambisonic components up to third order. Horizontal-only recordings or mixes are the most commonly encountered mixed-order signals, because the horizontal plane is by far the most likely location of musical or other performers, and the vast majority of playback systems deployed today does not have height capability. Horizontal- only signal sets are derived by following along the edges of the pyramid of spherical harmonics (see illustration) and taking only the outermost components. Observe how the other components in each order have either nulls on their equators or lobes with broader expansion than the outer ones, adding no additional resolution information.

The `NULL` literal is untyped in SQL, meaning that it is not designated as an integer, character, or any other specific data type. Because of this, it is sometimes mandatory (or desirable) to explicitly convert Nulls to a specific data type. For instance, if overloaded functions are supported by the RDBMS, SQL might not be able to automatically resolve to the correct function without knowing the data types of all parameters, including those for which Null is passed. Conversion from the `NULL` literal to a Null of a specific type is possible using the `CAST` introduced in SQL-92.

Each installment of the first season was a self-contained episode except for the two-part finale. When the User loads a game, a game cube drops on a random location in Mainframe, sealing it off from the rest of the system and turning it into a gamescape. Bob frequently enters the games, reboots to become a game character, and fights the User's character to save the sector. If the User wins a game, the sector the cube fell in is destroyed, and the sprites and binomes who were caught within are turned into energy-draining, worm-like parasites called nulls.

One method is to rely on a second loop antenna located at a second location, or to move the receiver to that other location, thus relying on triangulation. Instead of triangulation, a second dipole or vertical antenna can be electrically combined with a loop or a loopstick antenna. Called a sense antenna, connecting and matching the second antenna changes the combined radiation pattern to a cardioid, with a null in only one (less precise) direction. The general direction of the transmitter can be determined using the sense antenna, and then disconnecting the sense antenna returns the sharp nulls in the loop antenna pattern, allowing a precise bearing to be determined.

Because the Feline trio of Tom, Cat, and Pussy are in disgrace, they enter a dangerous contest to regain their social status. After the Felines and their Caprine companions win the competition, a no-holds-barred game of capture the flag, they are educated about Colene and Darius and trained to become the next mode anchors. The six nulls, along with four unknown individuals, become co- anchors as soon as Seqiro frees his anchor, and Colene, Darius, Nona, and Burgess are immediately captured by Ddwng. The companions are taken to the primitive planet Chains, where they are forced to remain until Darius agrees to give the Chip to Ddwng.

When mounted horizontally, the radiation peaks at right angles (90°) to the conductor, with nulls in the direction of the dipole. Neglecting electrical inefficiency, the antenna gain is equal to the directive gain, which is 1.5 (1.76 dBi) for a short dipole, increasing to 1.64 (2.15 dBi) for a half-wave dipole. For a 5/4 wave dipole the gain further increases to about 5.2 dBi, making this length desirable for that reason even though the antenna is then off-resonance. Longer dipoles than that have radiation patterns that are multi-lobed, with poorer gain (unless they are much longer) even along the strongest lobe.

The masks change constantly in a slew of different ways, usually while obscured from the home viewer. Episodes 1 and 10 of season 2, and episode 4 of season 3 showed her mask changing on screen in an instant. She has transfinite power reserves, meaning that she has near limitless stores of energy to draw from, and as such, is quite powerful herself. Her powers include energy beams and fireballs, altering gravity (once causing Bob to stop and hover in midair) and being able to fly, shrugging off severe damage and controlling nulls (sprites downgraded to slug-like status for losing to the User in a game).

Codd indicated in his 1990 book The Relational Model for Database Management, Version 2 that the single Null mandated by the SQL standard was inadequate, and should be replaced by two separate Null-type markers to indicate the reason why data is missing. In Codd's book, these two Null-type markers are referred to as 'A-Values' and 'I-Values', representing 'Missing But Applicable' and 'Missing But Inapplicable', respectively. Codd's recommendation would have required SQL's logic system be expanded to accommodate a four-valued logic system. Because of this additional complexity, the idea of multiple Nulls with different definitions has not gained widespread acceptance in the database practitioners' domain.

Pressure standing waves in a closed tube: modes 1, 2 and 3 Nulls in a standing wave pattern on a transmission line Standing waves can be caused by a wave being reflected back through the transmission medium in which it arrived. If the incident and reflected waves are transmitted without loss then there will be points along the transmission path where the incident and reflected waves exactly cancel each other due to them being in antiphase. Standing waves are found in wind musical instruments. Wind instruments consist of a tube which acts as an acoustic transmission line in which standing waves are set up.

In a radio antenna's radiation pattern, the main lobe, or main beam, is the lobe containing the higher power. This is the lobe that exhibits the greater field strength. The radiation pattern of most antennas shows a pattern of "lobes" at various angles, directions where the radiated signal strength reaches a maximum, separated by "nulls", angles at which the radiation falls to zero. In a directional antenna in which the objective is to emit the radio waves in one direction, the lobe in that direction is designed to have higher field strength than the others, so on a graph of the radiation pattern it appears biggest; this is the main lobe.

The language also added a number of direct-mode commands like to exit BASIC and return to DOS, to renumber the lines in the program, and which defined how many nulls to print after pressing return, to use as fill characters. Version 5 was assembled for 8-digit floating-point precision. North Star would re-assemble the interpreter for customers with a different precision, up to 14 digits. Some other dialects of BASIC were created that were based on and inspired by North Star BASIC, such as BaZic (a rewrite of North Star BASIC, taking advantage of the faster Zilog Z80 instructions), Megabasic and S.A.I.L.B.O.A.T. (a basic optimized for Z80 and X86 MS-DOS).

Secondly, this issue of control is related to the second point: the belief that an omnibus test offers protection is not completely accurate. When the complete null hypothesis is true, weak family-wise Type I error control is facilitated by the omnibus test; but, when the complete null is false and partial nulls exist, the F-test does not maintain strong control over the family-wise error rate. A third point, which Games (1971) demonstrated in his study, is that the F-test may not be completely consistent with the results of a pairwise comparison approach. Consider, for example, a researcher who is instructed to conduct Tukey's test only if an alpha-level F-test rejects the complete null.

The microphones nulls (zero pickup point) are set to face the main sound source with positive polarities outward facing, therefore very effectively minimizing the direct sound pickup as well as echoes from the back of the hall The back two microphones are mixed to the surround channels, with the front two channels being mixed in combination with the front array into L and R. Another ambient technique is the IRT (Institut für Rundfunktechnik) cross. Here, four cardioid microphones, 90 degrees relative to one another, are placed in square formation, separated by 21–25 cm. The front two microphones should be positioned 45 degrees off axis from the sound source. This technique therefore resembles back to back near- coincident stereo pairs.

The pair is known as a doublet, or dipole, and the radiation of this combination is similar to that of a very small dynamic loudspeaker operating without a baffle. The directivity of a dipole is a figure 8 shape with maximum output along a vector that connects the two sources and minimums to the sides when the observing point is equidistant from the two sources, where the sum of the positive and negative waves cancel each other. While most drivers are dipoles, depending on the enclosure to which they are attached, they may radiate as monopoles, dipoles (or bipoles). If mounted on a finite baffle, and these out of phase waves are allowed to interact, dipole peaks and nulls in the frequency response result.

However, the presence of many tightly grouped shapes in the Voynich manuscript (such as "or", "ar", "ol", "al", "an", "ain", "aiin", "air", "aiir", "am", "ee", "eee", among others) does suggest that its cipher system may make use of a "verbose cipher", where single letters in a plaintext get enciphered into groups of fake letters. For example, the first two lines of page f15v (seen above) contain "" and "", which strongly resemble how Roman numbers such as "CCC" or "XXXX" would look if verbosely enciphered. The theory that the encryption system started from a fundamentally simple cipher and then was augmented by adding nulls (meaningless symbols), homophones (duplicate symbols), transposition cipher (letter rearrangement), false word breaks, and more is also entirely possible.

Due to the discrepancy between the required "seat time" for a high school diploma in Guilford County and the actual time spent in class in a college setting, juniors and seniors must make up the difference with mandatory volunteer work. A license was since issued that nulls the "seat time" rule for ECG juniors and seniors, but upperclassmen are still required to complete a certain amount of volunteer work each academic year. Both underclassmen and upperclassmen participate in Early College clubs, usually held after underclassmen classes. Clubs include an Interact Club, Math Team, SAI Service club, five FIRST Robotics teams (under the umbrella of ECG Robotics, Inc.), Academic Quiz Bowl team, Student Council, Student Human Relations Committee, EducateUS, Science Olympiad, Yearbook Committee, and Speech and Debate Club.

In terms of computing and placenames databases, the coordinates for Null Island were added to the Natural Earth public domain map dataset –2011, after which the term came into wide use (although there is evidence of it being used previously). Since then, the 'island' has through fiction been given a geography (based on the setting of the video game Myst), history, and flag. Natural Earth describes the entity as a "1 meter square island" with "scale rank 100, indicating it should never be shown in mapping". The name 'Null' refers to the two zero coordinates, as null values (indicating an absence of data) are often coerced to a value of 0 when converted to an integer context or "no-nulls allowed" context.

Occasionally, monitoring the execution of a target program can help to highlight random errors that appear (or sometimes disappear) while monitoring but not in real execution. This can happen when the target program is loaded at a different location than normal because of the physical presence of the monitoring program in the same address space. If the target program picks up the value from a "random" location in memory (one it doesn't 'own' usually), it may for example be nulls (X"00") in almost every normal situation and the program works OK. If the monitoring program shifts the load point, it may pick up say X"FF" and the logic would cause different results during a comparison operation. Alternatively, if the monitoring program is now occupying the space where the value is being "picked up" from, similar results might occur.

In extreme cases, where the interference is either deliberate or all attempts to get rid of the offending device have proved futile, it may be possible to look at changing the parameters of the network. Changing collinear antennas for high gain directional dishes normally works very well, since the narrow beam from a high gain dish will not physically "see" the interference. Often sector antennae have sharp "nulls" in their vertical pattern, so changing the tilt angle of sector antennas with a spectrum analyzer connected to monitor the strength of the interference can place the offending device within the null of the sector. High gain antennas on the transmitter end can "overpower" the interference, although their use may cause the effective radiated power (ERP) of the signal to become too high, and so their use may not be legal.

Null has been the focus of controversy and a source of debate because of its associated three- valued logic (3VL), special requirements for its use in SQL joins, and the special handling required by aggregate functions and SQL grouping operators. Computer science professor Ron van der Meyden summarized the various issues as: "The inconsistencies in the SQL standard mean that it is not possible to ascribe any intuitive logical semantics to the treatment of nulls in SQL."Ron van der Meyden, "Logical approaches to incomplete information: a survey" in Chomicki, Jan; Saake, Gunter (Eds.) Logics for Databases and Information Systems, Kluwer Academic Publishers , p. 344; PS preprint (note: page numbering differs in preprint from the published version) Although various proposals have been made for resolving these issues, the complexity of the alternatives has prevented their widespread adoption.

Whereas the result of a join (or inner join) consists of tuples formed by combining matching tuples in the two operands, an outer join contains those tuples and additionally some tuples formed by extending an unmatched tuple in one of the operands by "fill" values for each of the attributes of the other operand. Outer joins are not considered part of the classical relational algebra discussed so far. The operators defined in this section assume the existence of a null value, ω, which we do not define, to be used for the fill values; in practice this corresponds to the NULL in SQL. In order to make subsequent selection operations on the resulting table meaningful, a semantic meaning needs to be assigned to nulls; in Codd's approach the propositional logic used by the selection is extended to a three- valued logic, although we elide those details in this article.

When electromechanical teleprinters were used as computer output devices, one or more null characters were sent at the end of each printed line to allow time for the mechanism to return to the first printing position on the next line. On punched tape, the character is represented with no holes at all, so a new unpunched tape is initially filled with null characters, and often text could be "inserted" at a reserved space of null characters by punching the new characters into the tape over the nulls. Today the character has much more significance in C and its derivatives and in many data formats, where it serves as a reserved character used to signify the end of a string,"A string is a contiguous sequence of characters terminated by and including the first null character" — ANSI/ISO 9899:1990 (the ANSI C standard), section 7.1.1 often called a null-terminated string.

One of his passwords was revealed to be "Yaddi Yaddi Yadda!" Phong always has the right equipment or knowledge, often handy in whatever sort of situation; in one episode, Bob was shocked to find that Phong had prepared a countermeasure specifically to handle a giant monster made entirely of Nulls stomping around the city. He acts a wise therapist whom many come to for advice about their problems, but the majority of the time his advice isn't very helpful and he urges for sprites to figure things out on their own. The character Phong's name is an allusion to the game Pong—he has a rule that any who seek his advice must first play him in a game of physical Pong, shown on-screen in the first few episodes—and to Phong shading, an interpolation method (itself named after computer scientist Bui Tuong Phong) used in three-dimensional graphics rendering.

Turning the movable disk I will juxtapose this letter to the agreed upon index B and, successively, as required by the logic of writing, I will continue giving the value of the capitals to the small letters. To further confuse the scrutinizers you can also agree with your correspondent that the capital letters intermingled in the message have the function of nulls and must be disregarded, or you may resort to similar conventions, which are not worth recalling. Thus changing the position of the index by rotating the movable disk, one will be able to express the phonetic and semantic value of each capital letter by means of twenty-four different alphabetic characters, whereas each small letter can correspond to any capital letter or to any of the four numbers in the alphabet of the stationary disk. Now I come to the convenient use of the numbers, which is admirable.

After the end of the third season, two TV movies were produced in 2001: Daemon Rising, which addressed the problem the Guardians were facing in season three (and used much of Terabyte Rising), and My Two Bobs, which brings back a corroded and mutated Megabyte in a cliffhanger ending. The two movies, broken up into eight episodes in its U.S. run on Cartoon Network's Toonami, revealed much of Mainframe's history, including the formation of Lost Angles, Bob's arrival in the system, and the origin of Megabyte and Hexadecimal. The films end with Megabyte in control of the Principal Office, and the characters scattered and about to be hunted down. It is revealed that the nulls still possess their old sentience and intelligence: The heroes manage to put the null that was once Dot's father into a robot, enabling him to move and speak like he used to.

The computer is powered up and nulls its velocity shafts; the gyros are powered by 115 V and 400 Hz and revving up; the platform is levelled in pitch, inner and outer roll relative to the aircraft using the gimbal synchrotransmitters; and the azimuth axis is driven to the grid north direction using the magnetic heading sensor. This phase of Alignment takes 1 minute and is called coarse align. After this 1 minute the system switches to the fine align phase, during which the gyro spin motor power is brought down to 95 V and 375 Hz to avoid any magnetic interference with any other aircraft system using 400 Hz. The levelling of the platform is taken over by the X and Y accelerometers sensing even the smallest component of gravity which is an indication of not being precisely level. The levelling of the stable element is achieved by torquing the respective gyro torquers which makes the gimbal motors to follow up and level the stable element.

The following SQL schema is one possible expression of the Suppliers-and-Parts database.

Since the magnetic (and electric) fields of an electromagnetic wave in free space are transverse (no component in the direction of propagation), it can be seen that this magnetic field and that of a small loop antenna will be at right angles, and thus not coupled. For the same reason, an electromagnetic wave propagating within the plane of the loop, with its magnetic field perpendicular to that plane, is coupled to the magnetic field of the coil. Since the transverse magnetic and electric fields of a propagating electromagnetic wave are at right angles, the electric field of such a wave is also in the plane of the loop, and thus the antenna's polarization (which is always specified as being the orientation of the electric, not the magnetic field) is said to be in that plane. Thus mounting the loop in a horizontal plane will produce an omnidirectional antenna which is horizontally polarized; mounting the loop vertically yields a weakly directional antenna with vertical polarization and sharp nulls along the axis of the loop.
