This "phase shifting" results in constructive interference between waves arriving from the desired direction, which amplifies them.
In early 22016, Mr. Reich envisioned a phasing machine, so the group paired him with the engineer Larry Owens to create the Phase Shifting Pulse Gate.
The house lights were turned bright, but aside from a gently swaying silhouette, Dean Blunt was all but invisible for the 45-ish minutes of funhouse grime, distended folk-rock, and Reichian phase shifting he delivered from the stage.
In the grating-based instance, phase-shifting is accomplished by translating the grating perpendicular to the rulings, while multiple images are recorded. The continued developments in phase shifting PDI have achieved accuracy orders of magnitude greater than standard Fizeau based systems. Phase-shifting [see Interferometry] versions have been created to increase measurement resolution and efficiency. These include a diffraction grating interferometer by Kwon and the Phase-Shifting Point Diffraction Interferometer.
As noted above, the MT1 receptor has been shown to have a hand in phase shifting but this role is secondary to that of the MT2 receptor. In experiments involving MT1 KO mice (and WT as a control) both WT and MT1 KO groups exhibited phase shifting activity. On the flip side, MT2 KO mice were not able to phase shift suggesting that the MT2 receptor is necessary for phase shifting the internal circadian clock.
5853, pp. 243-251 (2005) One possibility is to eliminate absorbers altogether and use "chromeless" masks, relying solely on phase-shifting for imaging. The emergence of immersion lithography has a strong impact on photomask requirements. The commonly used attenuated phase-shifting mask is more sensitive to the higher incidence angles applied in "hyper-NA" lithography, due to the longer optical path through the patterned film.
The former method is attenuated phase-shifting, and is often considered a weak enhancement, requiring special illumination for the most enhancement, while the latter method is known as alternating-aperture phase- shifting, and is the most popular strong enhancement technique. As leading- edge semiconductor features shrink, photomask features that are 4× larger must inevitably shrink as well. This could pose challenges since the absorber film will need to become thinner, and hence less opaque.Y. Sato et al.
The change in electrical activity manifests itself as a phase shift within the organism. Further research led them to find that phase shifting is a calcium-dependent process. They found that lowering extracellular levels of calcium actually prevents the organism from phase shifting in response to light without affecting the response of the neurons to light. Around the same time, while Block and McMahon were conducting this experiment, other scientists discovered how to clone the period gene, marking an exciting time in the young field of chronobiology.
FIgure 3: Phase-shifting point diffraction interferometer design proposed by Gary Sommargren Gary Sommargren proposed a point diffraction interferometer design which directly followed from the basic design where parts of the diffracted wavefront was used for testing and the remaining part for detection as shown in Figure 3. This design was a major upgrade to existing systems. The scheme could accurately measure the optical surface with variations of 1 nm. The phase shifting was obtained by moving the test part with a piezo electric translation stage.
Features 150 nm or below in size generally require phase-shifting to enhance the image quality to acceptable values. This can be achieved in many ways. The two most common methods are to use an attenuated phase-shifting background film on the mask to increase the contrast of small intensity peaks, or to etch the exposed quartz so that the edge between the etched and unetched areas can be used to image nearly zero intensity. In the second case, unwanted edges would need to be trimmed out with another exposure.
In combination with other information gathered by the radar during the same scan (dual polarization products and phase shifting due to the Doppler effect), meteorologists can distinguish between hail, rain, snow, biologicals (birds, insects), and other atmospheric phenomena.
Laguë, M., and S.G. Reebs. 2000, Phase-shifting the light- dark cycle influences food-anticipatory activity in golden shiners. Physiology and Behavior 70: 55-59. They can also do this when there is more than one mealtime a day.
The photic response is likely linked to effects of light on circadian rhythms. In addition, focal application of melatonin can decrease firing activity of these neurons, suggesting that melatonin receptors present in the SCN mediate phase-shifting effects through the SCN.
Mushok uses a Lexicon Rackmount Multi-Effects Processor for the vast majority of his effects, including phase shifting, flanging, and delay. The only pedals he has really used are a Boss OC-3 Super Octave pedal and a Boss NS-2 Noise Suppressor.
Capacitor-run induction motors have a permanently connected phase- shifting capacitor in series with a second winding. The motor is much like a two-phase induction motor. Motor-starting capacitors are typically non- polarized electrolytic types, while running capacitors are conventional paper or plastic film dielectric types.
The lattice phase equaliser was invented by Otto Zobel.Zobel, O J, Phase-shifting network, US patent 1 792 523, filed 12 March 1927, issued 17 Feb 1931.Zobel, O J, Distortion Compensator, US patent 1 701 552, filed 26 June 1924, issued 12 Feb 1929. using a filter topology proposed by George Campbell.
In 1965, influenced by Terry Riley's use of tape looping and delay, the American composer Steve Reich started experimenting with looping techniques and accidentally discovered the potential of gradual phase shifting as a compositional resource.Mertens, Wim. 1983. American Minimal Music: La Monte Young, Terry Riley, Steve Reich, Philip Glass, p.37 & 48\.
MVA 220/155 kV phase-shifting transformer. A phase angle regulating transformer, phase angle regulator (PAR, American usage), phase-shifting transformer, phase shifter (West coast American usage), or quadrature booster (quad booster, British usage), is a specialised form of transformer used to control the flow of real power on three-phase electric transmission networks. For an alternating current transmission line, power flow through the line is proportional to the sine of the difference in the phase angle of the voltage between the transmitting end and the receiving end of the line.The "equal area criteria" for power system stability requires that this angle be less than 90 degrees, so for practical purposes this angle will be measurably less than 90 degrees.
The sleep promoting effects of melatonin has been tied to the activation of the MT1 receptor in the suprachiasmatic nucleus (SCN) which has an inhibitory effect on brain activity. While the phase shifting activity of melatonin has largely been linked to the MT2 receptor, there is evidence to suggest that the MT1 receptor plays a role in the process of entrainment to light-dark cycles. This evidence comes from an experiment in which wild-type (WT) mice and MT1 knock-out (KO) mice were given melatonin and their rates of entrainment were observed. Entrainment was observed to accelerate in WT mice upon melatonin dosage but not in MT1 KO mice which lead to the conclusion that MT1 plays a role in phase-shifting activity.
Planar transmitarray fed by a horn antenna. Structure showing unit cells. A transmitarray antenna (or just transmitarray) is a phase-shifting surface (PSS), a structure capable of focusing electromagnetic radiation from a source antenna to produce a high-gain beam. Transmitarrays consist of an array of unit cells placed above a source (feeding) antenna.
The full statement is repeated once. Reich re-recorded the fragment "come out to show them" on two channels, which initially play in unison. They quickly slip out of sync to produce a phase shifting effect, characteristic of Reich's early works. Gradually, the discrepancy widens and becomes a reverberation and, later, almost a canon.
The Doctor also realises the sarcophagus Clara and Mrs. Pitt's granddaughter Maisie had found in the storage car is for capturing the Foretold. Professor Moorhouse and Captain Quell are the next targets killed by the Foretold. The Doctor and chief engineer Perkins identify that the Foretold is draining energy from its victims using phase-shifting technology.
The induction regulator was an early device used to control the voltage of electric networks. Since the 1930s it has been replaced in distribution network applications by the tap transformer. Its usage is now mostly confined to electrical laboratories, electrochemical processes and arc welding. With minor variations, its setup can be used as a phase-shifting power transformer.
There is a background oscillation in the hippocampus in the theta band (4 – 8 Hz). As the animal approaches the landmark, the spiking of the place cell moves earlier in phase relative to the background theta oscillation, so that the phase offset essentially measures or represents the distance. This phase shifting relative to spatial distance is called phase precession.
The last is the main loop. The other two are minor loops. The forward path, considering only the forward path without the minor loop feedback, has three unavoidable phase shifting stages. The motor inductance and winding resistance form a low-pass filter with a bandwidth around 200 Hz. Acceleration to velocity is an integrator and velocity to position is an integrator.
DHM performs static measurements of 3D surface topography as many other 3D optical profilometers (white light interferometers, confocal, focus variation, … ). It enables to retrieve, roughness and shape of many surfaces. Use of multiple wavelengths enable to overcome the l/4 limit of traditional phase shifting interferometers. Applications have been demonstrated on many samples such as medical implants, watch components, micro components, micro-optics.
1: Phase shifting (delay between maximum/minimum external temperature and internal temperature). 2: Amplitude dampening (the reduction in maximum or minum internal temperature relative to that of the external temperature). Due to its density, compacted earth acts as thermal mass, meaning that it stores heat and releases it again slowly. Compacted soil is more of a conductor of heat than an insulator.
From 1967 Reich began exploring the gradual phase shifting technique in the context of composed music for instruments. The first of a series of works that would elaborate on this method was Piano Phase, composed in 1967.Mertens (1983), p.49. Composed phase music features two or more instruments playing a repetitive phrase (part) in a steady but not identical tempo.
Since the SCN is responsible for mediating the production of melatonin by the pineal gland, it creates a feedback loop that regulates the production of melatonin according to the master circadian clock. As was discussed previously, the MT1 receptor is largely thought of as the major player in sleep-promotion and the MT2 receptor is most strongly linked to phase shifting activity. Both major subtypes of the melatonin receptor are expressed in relatively large amounts in the SCN which allow it to both regulate sleep-wake cycles and induce phase shifting in response to natural light-dark cycles. This functional diversity of melatonin receptors helps give the SCN the ability to not only keep near 24-hour time and entrain to an exactly 24-hour period, but also regulate, among other factors, wakefulness and activity throughout this cycle.
He asked Hazen to verify that the model could accurately reproduce the behavior of machines during load changes. Design and construction was carried out jointly by General Electric and MIT. When first demonstrated in June 1929, the system had eight phase-shifting transformers to represent synchronous machines. Other elements included 100 variable line resistors, 100 variable reactors, 32 fixed capacitors, and 40 adjustable load units.
The second movement, while much slower, plays with the same ideas of phase shifting and melodic imitation. The persistent use of staggered repetition of melodic material is at the very heart of the movement's construction. In the nature of the patterns, the movements harmonic combination reflects the contemporaneously composed Sextet (1985). However, this movement's change of tempo is abrupt and halved, establishing an ambiguity between measured groupings.
Multiple features of this sort are added, and the combined pattern produces the original feature. Typically, on the mask these additional features look like additional lines lying parallel to the desired feature. Adding these enhancement features has been an area of continual improvement since the early 2000s. In addition to using additional patterning, modern systems add phase- shifting materials, multiple-patterning and other techniques.
Surveillance aircraft, e.g. AWACS, have only the sum and difference antennas, but can also be space stabilized by phase shifting the beam down or up when pitched or rolled. The SSR antenna is typically fitted to the PSR antenna, so they point in the same direction as the antennas rotate. The omnidirectional antenna is mounted near and high, usually on top of the radome if equipped.
Transmitarrays can be split into two types: fixed and reconfigurable. As described earlier, a transmitarray is a phase-shifting surface consisting of an array of unit cells. These focus the wavefronts from a feeding antenna into a narrower beamwidth. By applying a progressive phase shift across the aperture of the transmitarray, the beam can be focused and steered towards a direction away from boresight (0° angles).
Zone plates consist of a substrate with concentric zones of a phase-shifting or absorbing material with zones getting narrower the larger their radius. The zone widths are designed so that a transmitted wave gets constructive interference in a single point giving a focus. Zone plates can be used as condensers to collect light, but also for direct full field imaging in e.g. an X-ray microscope.
For effects, Lifeson is known to use chorus, phase shifting, and flanging. Throughout his career, he has used well-known pedals such as the Electro-Harmonix Electric Mistress flanger, the BOSS CE-1 chorus, the Dunlop crybaby wah, among others. Lifeson and his guitar technician Scott Appleton have discussed in interviews Lifeson's use of Fractal Audio's Axe-FX, Apple Inc.'s MainStage, and Native Instruments' Guitar Rig.
A microscanner, or micro scanning mirror, is a microoptoelectromechanical system (MOEMS) in the category of micromirror actuators for dynamic light modulation. Depending upon the type of microscanner the modulatory movement of a single mirror can be either translatory or rotational, on one or two axes. In the first case, a phase shifting effect takes place. In the second case, the incident light wave is deflected.
When the rotor comes close to operating speed, a centrifugal switch (or current-sensitive relay in series with the main winding) disconnects the capacitor. The start capacitor is typically mounted to the side of the motor housing. These are called capacitor-start motors, and have relatively high starting torque. There are also capacitor-run induction motors which have a permanently connected phase-shifting capacitor in series with a second winding.
In most types, unlike voltmeters and wattmeters, there is no restoring spring torque for the magnetically produced torques to overcome; the pointer system is free to rotate continually. Synchroscopes have a damping vane to smooth out vibration of the moving system. A polarized-vane synchroscope has a field winding with a phase-shifting network arranged to produce a rotating magnetic field. The field windings are connected to the "incoming" machine.
The recorded seismic trace is considered the real part of the complex trace. By phase shifting the recorded trace by 90 degrees, we can obtain the imaginary part of the complex trace. The complex seismic trace is a complex function whose real and imaginary part are the previously mentioned. From the complex trace, one can now define seismic attributes such as the complex amplitude, phase, instantaneous phase and instantaneous frequency.
The incident light is split into two rays, parallel to each other and displaced by an amount depending on the thickness of the mirror. The rays are recombined at the second mirror and ultimately imaged onto a screen. If a phase-shifting element is added to one arm of the interferometer, then the displacement it causes can be determined by simply counting the interference fringes, i.e., the minima.
The resistor can be replaced with a FET in its ohmic mode to implement a voltage-controlled phase shifter; the voltage on the gate adjusts the phase shift. In electronic music, a phaser typically consists of two, four or six of these phase-shifting sections connected in tandem and summed with the original. A low-frequency oscillator (LFO) ramps the control voltage to produce the characteristic swooshing sound.
Frequency-dependant phase shifting of the elements of the array can be used to compensate for the squint, which leads to the concept of a squintless antenna or feed. ;Design :In some cases the antenna may be designed to create a squint. For example, an antenna which is used to communicate with a satellite but must remain in a vertical configuration. Squint is also required in conical scanning.
Dr Charles Vickery Drysdale FRSE CB OBE (1874–1961) was an English electrical engineer and social reformer. He is remembered for opening the first birth control clinic in Britain in 1921 and co-founding the Family Planning Association in 1930. As an engineer he is remembered as the inventor of the Phase-shifting transformer. He was co-founder of the Institute of Physics and served as its Vice-President 1932–1936.
At intermediate values of power factor, the torques provided by the two coils add and the pointer takes up intermediate positions. Another electromechanical instrument is the polarized-vane type. In this instrument a stationary field coil produces a rotating magnetic field, just like a polyphase motor. The field coils are connected either directly to polyphase voltage sources or to a phase-shifting reactor if a single-phase application.
In reflection DHM, the phase shift image forms a topography image of the object. Transparent objects, like living biological cells, are traditionally viewed in a phase-contrast microscope or in a differential interference contrast microscope. These methods visualize phase shifting transparent objects by distorting the bright field image with phase shift information. Instead of distorting the bright field image, transmission DHM creates a separate phase shift image showing the optical thickness of the object.
The field winding is a three-phase winding, with the phases connected to both the running and incoming sources through a phase- shifting "impedor" network containing resistors, capacitors, and inductors. In this instrument, conceptually the field winding produces two rotating magnetic fields due to the running and incoming sources. The iron vane moves in response to the resultant sum of the two fields. The cross-coil synchroscope somewhat resembles a wound-field induction motor.
Some noted metamaterial antennas employ negative-refractive-index transmission-line metamaterials (NRI-TLM). These include lenses that can overcome the diffraction limit, narrowband and broadband phase-shifting lines, small antennas, low-profile antennas, antenna feed networks, novel power architectures, and high-directivity couplers. Loading a planar metamaterial network of TLs with series capacitors and shunt inductors produces higher performance. This results in a large operating bandwidth while the refractive index is negative.
It is not self-starting. The clock requires manual starting by a small knob on the back, while the older Hammond organs had an auxiliary starting motor connected by a spring-loaded manually operated switch. Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized.
After phase shifting and filtering, the resulting electronic signal gives a measure of how far the laser carrier is off resonance with the cavity and may be used as feedback for active stabilization. The feedback is typically carried out using a PID controller which takes the PDH error signal readout and converts it into a voltage that can be fed back to the laser to keep it locked on resonance with the cavity.
Diurnal temperature changes between maximum and minimum temperatures can be modelled as a wave, as can seasonal temperature changes (see diagram). In architecture, the relationship between the maximum fluctuations of external temperature compared to internal temperature is termed amplitude dampening (or temperature amplitude factor). Phase shifting is the time take for the minimum external temperature to reach the interior. Partially covering a building with earth adds to the thermal mass of the structure.
Functionally similar units from competing manufacturers are generically known either as "psychoacoustic processors", "psychoacoustic exciters", "harmonic exciters", or "enhancers". In the 1990s and 2000s, broadly comparable products became available from BBE, Joemeek, SPL and Behringer. Most are analogue signal processors, although a few digital units began to appear in the 2000s. The BBE Sonic Maximiser uses a similar process of frequency-dependent phase shifting, as do other brands to a varying extent.
Ma Heng-Tai (马恒泰) as the phase shifting module designer, with Shi Mei-Ling (施美玲) handles the control portion. Ding You-Shi (丁友石) was put in charge of microelectronics. The design team begun its hectic workload/schedule in September 1992. Due to the technological bottlenecks China faced in the early 1990s, it was impossible to provide the power source for every single transceiver of the APAR.
Intra-pulse scalloping is improved by shortening the transmit pulse or by modulating the transmit pulse. This can include frequency or phase shifting associated with pulse compression. Moving target indicator (MTI) radar reduces the impact of blind velocity by using redundant detectors that introduce a compensating reverse phase shift undoes the phase shift caused by Doppler from reflector motion. This is also improved by using 3 or more pulses with staggering pulse intervals.
Federal Standard 1037C Early artificial lines were used in telephony research and took the form of a cascade of lattice phase equalisers to provide the necessary delay. The lattice phase circuit was invented by Otto Zobel in the 1920s.Zobel, O J, Phase-shifting network, US patent 1 792 523, filed 12 March 1927, issued 17 Feb 1931.Zobel, O J, "Theory and design of uniform and composite electric wave filters", Bell System Technical Journal, vol.
Commonly, a microscope objective is used to collect the object wave front. However, as the microscope objective is only used to collect light and not to form an image, it may be replaced by a simple lens. If a slightly lower optical resolution is acceptable, the microscope objective may be entirely removed. Digital holography comes in different flavors, such as off-axis Fresnel, Fourier, image plane, in-line, Gabor and phase-shifting digital holography, depending on the optical setup.
A two-phase rotor winding is connected to the incoming machine source by a phase-shifting network through brushes and slip rings. The stationary field winding is connected to the incoming source. In a Weston pattern synchroscope, the moving element is not free to rotate continuously and oscillates back and forth slowly as the two sources are brought into synchronism. The moving pointer is illuminated by a pilot lamp connected to a three-winding transformer fed by both sources.
Parallels include the advent of the simple Baroque continuo style following elaborate Renaissance polyphony and the simple early classical symphony following Bach's monumental advances in Baroque counterpoint. In addition, critics have often overstated the simplicity of even early minimalism. Michael Nyman has pointed out that much of the charm of Steve Reich's early music had to do with perceptual phenomena that were not actually played, but resulted from subtleties in the phase-shifting process.Nyman 1974, 133–34.
Therefore, it is sometimes classified as a norepinephrine–dopamine disinhibitor. It has no influence on the extracellular levels of serotonin. Agomelatine has shown an antidepressant-like effect in animal models of depression (learned helplessness test, despair test, chronic mild stress) as well as in models with circadian rhythm desynchronisation and in models related to stress and anxiety. In humans, agomelatine has positive phase shifting properties; it induces a phase advance of sleep, body temperature decline and melatonin onset.
It is undesirable for the angle to approach 90 degrees, as the power flowing decreases but the resistive losses remain. Very approximately, the allowable product of line length and maximum load is proportional to the square of the system voltage. Series capacitors or phase-shifting transformers are used on long lines to improve stability. High-voltage direct current lines are restricted only by thermal and voltage drop limits, since the phase angle is not material to their operation.
Electromechanical protective relays operate by either magnetic attraction, or magnetic induction. Unlike switching type electromechanical relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of induction disks, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts, and phase- shifting networks. Protective relays can also be classified by the type of measurement they make.
Spectrograms of phasing and flanging effects Flanging is one specific type of phase-shifting, or "phasing". In phasing, the signal is passed through one or more all-pass filters with non-linear phase response and then added back to the original signal. This results in constructive and destructive interference that varies with frequency, giving a series of peaks and troughs in the frequency response of the system. In general, the position of these peaks and troughs do not occur in a harmonic series.
A real-time scanner using digital fringe projection and phase- shifting technique (certain kinds of structured light methods) was developed, to capture, reconstruct, and render high-density details of dynamically deformable objects (such as facial expressions) at 40 frames per second. Recently, another scanner has been developed. Different patterns can be applied to this system, and the frame rate for capturing and data processing achieves 120 frames per second. It can also scan isolated surfaces, for example two moving hands.
The ability to learn temporal patterns in sequenced actions was investigated in elementary-school age children. Temporal learning depends upon a process of integrating timing patterns with action sequences. Children ages 6–13 and young adults performed a serial response time task in which a response and a timing sequence were presented repeatedly in a phase-matched manner, allowing for integrative learning. The degree of integrative learning was measured as the slowing in performance that resulted when phase-shifting the sequences.
Using various techniques such as immersion lithography and phase-shifting photomasks, it has indeed been possible to make images much finer than the wavelength—for example, drawing 30 nm lines using 193 nm light. Plasmonic techniques have also been proposed for this application. Heat-assisted magnetic recording is a nanophotonic approach to increasing the amount of data that a magnetic disk drive can store. It requires a laser to heat a tiny, subwavelength area of the magnetic material before writing data.
A benefit of using phase-shift masks in lithography is the reduced sensitivity to variations of feature sizes on the mask itself. This is most commonly used in alternating phase-shift masks, where the linewidth becomes less and less sensitive to the chrome width on the mask, as the chrome width decreases. In fact, even with no chrome the phase edge can still print, as noted above. Some cases of attenuated phase-shifting masks also demonstrate the same benefit (see left).
The phase-shifting (or phase-stepped) digital holography process entails capturing multiple interferograms that each indicate the optical phase relationships between light returned from all points on the illuminated object and a controlled reference beam of light. The optical phase of the reference beam is shifted from one sampled interferogram to the next. From a linear combination of these interferograms, complex-valued holograms are formed. These holograms contain amplitude and phase information of the optical radiation diffracted by the object, in the sensor plane.
In addition, the phase of the Kai oscillator can be shifted in response to environmental changes. However, unlike phase-shifting mechanisms characterized in eukaryotic organisms, photopigments do not appear to play a role in entrainment of the cyanobacterial clock. Instead, identified input mechanisms rely on biochemical changes that track photosynthetic reactions performed by the cyanobacterium, reactions that exhibit rate increases proportional to ambient light intensity. CikA and LdpA, for example, sense the redox state of the intracellular environment and relay changes to the Kai oscillator.
Combined with insulation, this results in both amplitude dampening and phase shifting. In other terms, earth sheltered structures receive both a degree of cooling in Summer and heating in Winter. This reduces need for other measures of heating and cooling, saving energy. A potential disadvantage of a thermally massive building in cooler climates is that after a prolonged period of cold, when the external temperature increases again, the structures internal temperature tends to lag behind and take longer to warm up (assuming no other form of heating).
Translated by J. Hautekiet; preface by Michael Nyman. London: Kahn & Averill; New York: Alexander Broude. . In discussing the technicalities of what has been termed a "phase shifting process" Reich has stated that it is related to infinite canon or round (music) in medieval music. The difference between phase music and traditional rounds, where two or more identical melodies are played with one starting after the other, is that the melodic phrases are generally short repeating patterns with the imitation being variable instead of fixed.
Surprisingly, it showed no such effects in healthy patients when taken before bed. In a test of phase shifted circadian cycle, TIK-301 showed efficacy in readjusting phase shifts in all physiological systems. While it has been shown to be effective in phase shifting circadian rhythm and reduced sleep latency, it has not been shown to help sleep maintenance, even at doses of 20 mg or 200 mg. In addition to a sleep aid, TIK-301 has been found useful in treating other disorders.
From 1801 to 1826 he was a bassoonist in the orchestra of the Paris Opera. In 1795 he was appointed professor of bassoon at the Conservatoire de Paris, a post he held until 1802 and then from 1824 to 1838. His most famous work was Duos Concertants, Op. 48, for horn and bassoon, which featured repetitive rhythmic motifs in phase shifting patterns and strikingly modern asymmetrical melodies. The most memorable effect he achieved with this piece was the portrayal of schadenfreude through jarring note patterns in the bassoon line.
In the Uniphase, sound acts upon the outside of the acoustic diaphragm while it simultaneously enters a phase-shifting acoustic network within the microphone. There, it acts upon the inside of the diaphragm. The diaphragm actuates a transducer converting its motions into equivalent electrical waves: an electric signal that can now be transmitted through an electronic medium like wires. Importantly, in the Uniphase, as sound arrives from the front of the microphone, the inner pressure reinforces the outer pressure, thus allowing noise picked up by the microphone system to be greatly reduced.
In addition to retina this receptor is expressed on the osteoblasts and is increased upon their differentiation. MT2 regulates proliferation and differentiation of osteoblasts and regulates their function in depositing bone. MT2 signaling seems also involved in the pathogenesis of type 2 diabetes. Activation of the MT2 receptor promotes vasodilation which lowers body temperature in the extremities upon daytime administration. The most notable of the functions that are largely mediated by the MT2 receptor is that of phase shifting the internal circadian clock to entrain to the Earth's natural light-dark cycle.
In the case of gradual phase shifting, initially the tempi of the different instruments will be almost identical, so that both parts are perceived to be sounding in unison and at the same tempo. Over time the phrases gradually shift apart, creating first a slight echo as one instrument plays a little behind the other. This is followed by what sounds like a doubling with each note heard twice. Next, a complex ringing effect arises, after which the phrases eventually return, back through doubling, echo, and unison, to an in-phase position.
Imprint lithography was shown to have desirable advantages for nanometer-scaled research and technology. Advanced deep UV photolithography can now offer sub-100 nm resolution, yet the minimum feature size and spacing between patterns are determined by the diffraction limit of light. Its derivative technologies such as evanescent near-field lithography, near-field interference lithography, and phase-shifting mask lithography were developed to overcome the diffraction limit. In the year 2000, John Pendry proposed using a metamaterial lens to achieve nanometer-scaled imaging for focusing below the wavelength of light.
Even at the 1.5 m wavelength, antennas of practical size had relatively low gain and very poor resolution; the transmitter antenna created a fan-shaped signal over 90 degrees wide. This was not useful for homing on a target, so some system of direction indication was required. The team seriously considered phase comparison as a solution, but could not find a suitable phase shifting circuit. Instead, a system of multiple receiver antennas was adopted, each one located so that only a certain section of the sky was visible.
In radio communication, multipath is the propagation phenomenon that results in radio signals reaching the receiving antenna by two or more paths. Causes of multipath include atmospheric ducting, ionospheric reflection and refraction, and reflection from water bodies and terrestrial objects such as mountains and buildings. Multipath propagation causes multipath interference, including constructive and destructive interference, and phase shifting of the signal; destructive interference causes fading. This may cause a radio signal to become too weak in certain areas to be received adequately, so multipath propagation can be detrimental in radio communication systems.
For receive (but not transmit), there is a distinction between analog and digital beamforming. For example, if there are 100 sensor elements, the "digital beamforming" approach entails that each of the 100 signals passes through an analog-to-digital converter to create 100 digital data streams. Then these data streams are added up digitally, with appropriate scale-factors or phase-shifts, to get the composite signals. By contrast, the "analog beamforming" approach entails taking the 100 analog signals, scaling or phase-shifting them using analog methods, summing them, and then usually digitizing the single output data stream.
This void also includes phase-shifting and beam-steering devicesBeam steering: is changing the direction of the main lobe of a radiation pattern. Note: In radio systems, beam steering may be accomplished by switching antenna elements or by changing the relative phases of the radio frequency radiation driving the elements. In optical systems, beam steering may be accomplished by changing the refractive index of the medium through which the beam is transmitted or by the use of mirrors or lenses. Source: from Federal Standard 1037C Real world applications in the THz band are still in infancy Moderate progress has been achieved.
Mu-tron Bi-Phase with expression pedal. Phaser effects were common in the 1970s, but the Mu-tron Bi-Phase combined two phase shifting circuits and in its time was the preferred "the phaser-lover's 'phasor'". It used technology from the old Uni-Vibe, with lamps and photo cells, and featuring two independent sweep generators which could be coupled, each with individual rate controls and the option to choose square or sine waves. The unit could be connected to an optional rocking foot pedal so that the effect could be operated in the manner of a wah-wah pedal.
Instrument transformers are high accuracy class electrical devices used to isolate or transform voltage or current levels. The most common usage of instrument transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuity from the high voltages or currents. The primary winding of the transformer is connected to the high voltage or high current circuit, and the meter or relay is connected to the secondary circuit. Instrument transformers may also be used as an isolation transformer so that secondary quantities may be used in phase shifting without affecting other primary connected devices.
The light-dark cycle is the most important environmental time cue for entraining circadian rhythms of most species, including humans, and bright artificial light exposure has been developed as a method to improve circadian adaptation in night workers. The timing of bright light exposure is critical for its phase shifting effects. To maximize a delay of the body clock, bright light exposure should occur in the evening or first part of the night, and bright light should be avoided in the morning. Wearing dark goggles (avoiding bright light) or blue-blocking goggles during the morning commute home from work can improve circadian adaptation.
Like the Green Martians, White Martians have numerous superhuman powers, including great strength/speed, flight, invisibility, telepathy, shape-changing, phase-shifting (sometimes called variable density) which allows them to be either invulnerably tough or completely immaterial, and "Martian vision", but they also share the Green Martians' vulnerability to fire. One of the White Martians disguised himself as the Hyperclan member Zum and had superspeed, though not on the level of the Flash. In Teen Titans vol.3 #41, Miss Martian was shown quickly recovering from the effects of Bombshell's neural scrambling powers as well as reforming after (apparently) having her head shot off.
Orbital angular momentum (OAM) multiplexing is a physical layer method for multiplexing signals carried on electromagnetic waves using the orbital angular momentum of the electromagnetic waves to distinguish between the different orthogonal signals. Orbital angular momentum is one of two forms of angular momentum of light. OAM is distinct from, and should not be confused with, light spin angular momentum. The spin angular momentum of light offers only two orthogonal quantum states corresponding to the two states of circular polarization, and can be demonstrated to be equivalent to a combination of polarization multiplexing and phase shifting.
When driven in phase, the radiation pattern of the reflective array is a single main lobe perpendicular to the plane of the antenna, plus several sidelobes at equal angles to either side. The more elements used, the narrower the main lobe and the less power is radiated in the sidelobes. The main lobe of the antenna can be steered electronically within a limited angle by phase shifting the drive signals applied to the individual elements. Each antenna element is fed through a phase shifter which can be controlled digitally, delaying each signal by a successive amount.
An extensive series of tests across the Atlantic were carried out by the USCGC Androscoggin starting in April 1956. Meanwhile, Loran-B proved to have serious problems keeping their transmitters in phase, and that work was abandoned. Minor changes were made to the Cytac systems to further simplify it, including a reduction in the pulse-chain spacing from 1200 to 1000 µs, the pulse rate changed to 20 pps to match the existing Loran-A system, and the phase-shifting between pulses to an alternating 0, 180-degree shift instead of 45 degrees at every pulse within the chain. The result was Loran-C.
The Foretold, finally released from its duty, offers the Doctor a salute before it disappears into a pile of dust, leaving behind its phase-shifting device. The Doctor evacuates Clara and the passengers to the TARDIS using the Foretold's device, and drops off the passengers to a nearby planet. He tells Clara that he tried hacking Gus to find who brought everyone to the train but Gus activated a self-destruct to keep the truth hidden. The Doctor explains that sometimes the only choices are bad choices and that he would move on to the next of the Foretold's victims until he beat it.
However, in the absence of either rods and cones or melanopsin, melanopsin becomes necessary for photoentrainment of the circadian oscillator and for other photic responses. To further investigate the role of melanopsin in light-induced phase shifting in mammals, the Provencio lab studied the locomotor activities of melanopsin-null mice (Opn4 -/-) in response to light. The Opn4 -/- mice showed similar circadian behaviors as the normal mice: they entrained to light/dark cycles and free-ran under constant darkness in a way expected from the normal mice. Researchers in Provencio's lab thus concluded that melanopsin was not involved in the functioning of the master clock oscillation.
In the off-axis configuration, a small angle between the reference and the object beams is used to prevent overlapping of the cross-beating contributions between the object and reference optical fields with the self-beating contributions of these fields. These discoveries were made by Emmett Leith and Juris Upatnieks for analog holography , and subsequently adapted to digital holography. In this configuration, only a single recorded digital interferogram is required for image reconstruction. Yet, this configuration can also be used in conjunction with temporal modulation methods, such as phase-shifting and frequency-shifting for high sensitivity measurements in low light Gross, Michel, and Michael Atlan.
To avoid this, power from the National Grid was used to provide a convenient phase-locked 50 Hz signal that was available across the entire nation. Each CH station was equipped with a phase-shifting transformer that allowed it to trigger at a specific point on the Grid waveform, selecting a different point for each station to avoid overlap. The output of the transformer was fed to a Dippy oscillator that produced sharp pulses at 25 Hz, phase-locked to the output from the transformer. The locking was "soft", so short-term variations in the phase or frequency of the grid were filtered out.
While feature sizes may be drawn as 65 nm or less, the wavelengths of light used for lithography are 193 nm and 248 nm. Fabrication of sub-wavelength features requires special imaging technologies, such as optical proximity correction and phase-shifting masks. The cost of these techniques adds substantially to the cost of manufacturing sub- wavelength semiconductor products, with the cost increasing exponentially with each advancing technology node. Furthermore, these costs are multiplied by an increasing number of mask layers that must be printed at the minimum pitch, and the reduction in yield from printing so many layers at the cutting edge of the technology.
In 1963, Riley made two electronic works using tape delay, Mescalin Mix and The Gift, which injected the idea of repetition into minimalism. In 1964, Riley's In C made persuasively engaging textures from the layered performance of repeated melodic phrases. The work is scored for any group of instruments and/or voices. In 1965 and 1966 Steve Reich produced three works—It's Gonna Rain and Come Out for tape, and Piano Phase for live performers—that introduced the idea of phase shifting, or allowing two identical phrases or sound samples played at slightly different speeds to repeat and slowly go out of phase with each other.
Doomsday developed weapons and abilities that countered the powers of an opponent. He managed to cancel out the pure-energy Radiant by slamming into him while generating a dark counter-energy; to greatly extend his claws and develop a poison to strike Superman in flight and reel him in; to breathe flames against the fire-sensitive Martian Manhunter, and apparently neutralize his defensive phase-shifting power.Superman (vol. 2) #175 Doomsday's skeleton protruded through his skin in razor-sharp spurs, which provided protection to his few vital organs (brain, eyes and nervous system), and acted as claw-like weapons on his hands, elbows, and knees.
Similarly, a lens-enhanced phased array antenna, similar to a transmitarray, has been demonstrated. By combining the beam steering capabilities of phased arrays and the focusing properties of transmitarrays, this hybrid antenna has a smaller form factor, and steers to ±45° in both planes with a 3.2 dB increase in directivity at this angle. Its reconfigurable phase-shifting surface (PSS) contained micro-electro-mechanical (MEMS) switches to change the length of resonators, sandwiched within an antenna-filter-antenna structure. The PSS created the optimal 2D phase distribution needed to achieve high-gain beam focusing, but the MEMS fabrication process was complex and costly, requiring a large number of control lines.
Phase sequence of two sources can be verified by measuring voltage between pairs of terminals and observing that terminals with very low voltage between them will have the same phase, whereas pairs that show a higher voltage are on different phases. Where the absolute phase identity is not required, phase rotation test instruments can be used to identify the rotation sequence with one observation. The phase rotation test instrument may contain a miniature three-phase motor, whose direction of rotation can be directly observed through the instrument case. Another pattern uses a pair of lamps and an internal phase-shifting network to display the phase rotation.
These responses help the MT2 receptor accomplish its role in phase shifting the circadian clock by adjusting the sensitivity and availability of the population of MT2 to melatonin. This desensitization and/or internalization is characteristic of many GPCRs. Often, binding of melatonin to MT2 and subsequent desensitization can lead to the internalization of that receptor which decreases the availability of membrane bound melatonin receptor which will prevent additional melatonin from having as robust of an effect as the initial application. Since there are regular rhythms in both of these receptor subtypes, the internalization and resulting decrease in receptor availability following administration of typical levels of melatonin will effectively shift the phase of this rhythm in MT2.
Initial contracts were offered to Sylvania and General Electric (GE), who both built experimental systems consisting of a single row of elements, essentially a slice of a larger array. Sylvania's design used MOSAR phase-shifting using time delays, while GE's used a "novel modulation scanning system". Sylvania's system won a contract for a test system, which became MAR-I when Nike-X took over from Zeus. To save money, the prototype MAR-I would only install antenna elements for the inner section of the original diameter antenna, populating the central . This had the side- effect of reducing the number of antenna elements from 6,405 to 2,245 but would not change the basic control logic.
In addition, Wilson had his engineer, Cal Harris, use what can (now) be considered classic studio sensibilities to take The Funk Brothers' backing tracks for "Nathan Jones" and give them a phase shifting sound at various points during the song. This was accomplished by either using a second recorder (as the Beatles would have done) or (less likely) an outboard processor such as the blue faced MXR flanger. Released as a single on April 15, 1971 with "Happy is a Bumpy Road" as the B-side, "Nathan Jones" peaked at number sixteen on the Billboard Pop Singles chart, number-eight on the Billboard R&B; chart. Overseas, the single went to number five on the UK Singles Chart.
Prominent features of minimalist music include repetitive patterns or pulses, steady drones, consonant harmony, and reiteration of musical phrases or smaller units. It may include features such as phase shifting, resulting in what is termed phase music, or process techniques that follow strict rules, usually described as process music. The approach is marked by a non-narrative, non-teleological, and non- representational approach, and calls attention to the activity of listening by focusing on the internal processes of the music.Johnson 1994, 744. The approach originated in the New York Downtown scene of the 1960s and was initially viewed as a form of experimental music called the New York Hypnotic School.Kostelanetz and Flemming 1997, 114–16.
Turntablism embodies the art of cutting, beat juggling, scratching, needle drops, phase shifting, back spinning and more to perform the transitions and overdubs of samples in a more creative manner (although turntablism is often considered a use of the turntable as a musical instrument rather than a tool for blending recorded music). Professional DJs may use harmonic mixing to choose songs that are in compatible musical keys. Recent advances in technology in both DJ hardware and software can provide assisted or automatic completion of some traditional DJ techniques and skills. Examples include phrasing and beatmatching, which can be partially or completely automated by utilizing DJ software that performs automatic synchronization of sound recordings, a feature commonly labelled "sync".
Current research suggests it occurs where the equivalent radius of the disk is less than 38% of the wavelength These broad classifications are a single way of sorting the types of levitation, but they are not definitive. Further work is being conducted on combining techniques to obtain greater abilities, such as the stable levitation of non axis-symmetric objects by combining standing wave levitation with a twin-trap (typically a single beam levitation technique). There is also a significant amount of work into combining these techniques with 3D printed phase shifting components for advantages such as passive field forming or higher spatial resolution. There is also significant variation in the control techniques.
Generally speaking, a PESA uses one receiver/exciter for the entire array. An active phased array or active electronically scanned array (AESA) is a phased array in which each antenna element has an analog transmitter/receiver (T/R) module which creates the phase shifting required to electronically steer the antenna beam. Active arrays are a more advanced, second-generation phased-array technology which are used in military applications; unlike PESAs they can radiate several beams of radio waves at multiple frequencies in different directions simultaneously. However, the number of simultaneous beams is limited by practical reasons of electronic packaging of the beam former(s) to approximately three simultaneous beams for an AESA.
Several tracks, including "Us and Them" and "Time", demonstrated Richard Wright's and David Gilmour's ability to harmonise their voices. In the 2003 Classic Albums documentary The Making of The Dark Side of the Moon, Waters attributed this to the fact that their voices sounded extremely similar. To take advantage of this, Parsons utilised studio techniques such as the double tracking of vocals and guitars, which allowed Gilmour to harmonise with himself. The engineer also made prominent use of flanging and phase shifting effects on vocals and instruments, odd trickery with reverb, and the panning of sounds between channels (most notable in the quadraphonic mix of "On the Run", when the sound of the Hammond B3 organ played through a Leslie speaker rapidly swirls around the listener).
The main criticisms of the original design are (1) that the required low-transmission reduces the efficiency, and (2) when the beam becomes too aberrated, the intensity on-axis is reduced, and less light is available for the reference beam, leading to a loss of fringe contrast. Lowered transmission was associated with lowered signal to noise ratio. These problems are largely overcome in the phase-shifting point diffraction interferometer designs, in which a grating or beamsplitter creates multiple, identical copies of the beam that is incident on an opaque mask. The test beam passes through a somewhat large hole or aperture in the membrane, without losses due to absorption; the reference beam is focused onto the pinhole for highest transmission.
Parallel or full field OCT using a charge-coupled device (CCD) camera has been used in which the sample is full- field illuminated and en face imaged with the CCD, hence eliminating the electromechanical lateral scan. By stepping the reference mirror and recording successive en face images a three-dimensional representation can be reconstructed. Three-dimensional OCT using a CCD camera was demonstrated in a phase-stepped technique, using geometric phase shifting with a Linnik interferometer, utilising a pair of CCDs and heterodyne detection, and in a Linnik interferometer with an oscillating reference mirror and axial translation stage. Central to the CCD approach is the necessity for either very fast CCDs or carrier generation separate to the stepping reference mirror to track the high frequency OCT carrier.
The tubes' source (driver) and load (antenna) were split and combined through +90 and −90 degree phase-shifting networks as in Doherty's amplifier. The unmodulated radio frequency carrier is applied to the control grids of both tubes, and with the same control grid bias points. Carrier modulation is applied to the screen grids of both tubes, but the screen grid bias points of the carrier and peak tubes are different and are established such that the peak tube is cut off when modulation is absent and the amplifier is producing rated unmodulated carrier power and both tubes are conducting and each tube is contributing twice the rated carrier power during 100% modulation as four times the rated carrier power is required to achieve 100% modulation.
The phase is proportional to the optical path length the light ray has traversed, and thus gives a measure of the integral of the refractive index along the ray path. The phase cannot be measured directly at optical or higher frequencies, and therefore needs to be converted into intensity by interference with a reference beam. In the visual spectrum this is done using Zernike phase-contrast microscopy, differential interference contrast microscopy (DIC) or interferometry. Zernike phase-contrast microscopy introduces a phase shift to the low spatial frequency components of the image with a phase-shifting annulus in the Fourier plane of the sample, so that high-spatial-frequency parts of the image can interfere with the low-frequency reference beam.
Early airborne radar systems generally operated purely as tracking systems, with a dedicated radar operator manually "tuning" the system to locate targets in a relatively narrow field-of-view in front of the aircraft. The searching area could be moved using a variety of methods, typically phase-shifting or lobe switching on lower frequency systems that required large antennas, or by moving the radar dish on microwave frequency radars. Engagements would start with ground controllers guiding the aircraft into the general area of the target via voice commands to the pilot, and once the aircraft got into range its own radar would pick up the target for the final approach when the radar operator would provide voice commands to the pilot. There was no real distinction between seeking out a target and tracking it.
X-ray interferometry is considered to be the most sensitive to the phase shift, of the 4 methods, consequently providing the highest density resolution in range of mg/cm3. But due to its high sensitivity, the fringes created by a strongly phase-shifting sample may become unresolvable; to overcome this problem a new approach called "coherence-contrast X-ray imaging" has been developed recently, where instead of the phase shift the change of the degree of coherence caused by the sample is relevant for the contrast of the image. A general limitation to the spatial resolution of this method is given by the blurring in the analyzer crystal which arises from dynamical refraction, i.e. the angular deviation of the beam due to the refraction in the sample is amplified about ten thousand times in the crystal, because the beam path within the crystal depends strongly on its incident angle.
The amplifier was usually configured as a grounded-cathode, carrier–peak amplifier using two vacuum tubes in parallel connection, one as a class B carrier tube and the other as a class B peak tube (power transistors in modern implementations). The tubes' source (driver) and load (antenna) were split and combined through +90 and −90 degree phase shifting networks.In order to circumvent Western Electric's patent, RCA utilized +90 and +270 degree phase shifts; as any student of phasor math knows, +270 degrees is equivalent to −90 degrees, therefore these are effectively the same as +90 and −90 degree phase shifts (RCA BT-50D, et al.) Alternate configurations included a grounded-grid carrier tube and a grounded-cathode peak tube whereby the driver power was effectively passed- through the carrier tube and was added to the resulting output power, but this benefit was more appropriate for the earlier and less efficient triode implementationsWE 117, CE 317A, CE 317B, WAPE station-built, et al.
