In monostatic sonar, the first thing the receiver can hear is the sound of the transmitted ping. This sound level is very high, and it is impossible to detect the echo during the ping duration τ. That means targets are undetectable within the circle of Cτ/2 radius, where C is sound speed in water. This area is usually referred to as “dead zone”.

The saturnian radiation belts are generally much weaker than those of Jupiter and do not emit much microwave radiation (with frequency of a few Gigahertz).

Since this drawing mechanism would normally make it difficult or impossible to detect a revoke (for instance, the player may not be able to follow suit, so they play off-suit and then immediately draw a card of the suit led), in the first phase of trick-play (before the stock is empty) players generally need not follow suit. A widespread game of this type is the Marriage group.

Some tourmaline gems, especially pink to red colored stones, are altered by heat treatment to improve their color. Overly dark red stones can be lightened by careful heat treatment. The pink color in manganese-containing near-colorless to pale pink stones can be greatly increased by irradiation with gamma-rays or electron beams. Irradiation is almost impossible to detect in tourmalines, and does not, currently, affect the value.

When manufactured correctly, the suit will move in the wind in the same way as surrounding foliage. Some ghillie suits are made with light and breathable material that allows a person to wear a shirt underneath. A well-made ghillie suit is extremely effective in camouflaging its wearer. A ghillie-suited soldier sitting perfectly still with local flora attached to their webbing is nearly impossible to detect visually, even at close range.

Many infections are not detectable immediately after exposure, so enough time must be allowed between possible exposures and testing for the tests to be accurate. Certain STIs, particularly certain persistent viruses like HPV, may be impossible to detect. Some treatment facilities utilize in-home test kits and have the person return the test for follow-up. Other facilities strongly encourage that those previously infected return to ensure that the infection has been eliminated.

Some of these methods detected not the submarine itself, but the disturbances it made in the sea. If its passage mixed layers of cold surface and underlying warm water, this would raise the apparent surface temperature slightly. This temperature change could be detected using an infrared-sensitive thermometer. Although impossible to detect by measuring the temperature in the wake, imaging the temperature of the overall sea would show the wake as standing out from it.

Fido, p. 78 The Daily Telegraph reported on 19 October that he said it was a recent "ginny kidney" from a 45-year-old female, but in the Star newspaper the same day Openshaw denied the report strongly, saying it was impossible to detect the age or gender of the individual whom the kidney had belonged to,Cook, p. 146; Fido, p. 78 or how long it had been preserved in spirits.

This type of shilling is illegal in some jurisdictions, but almost impossible to detect. It may be considered a form of unjust enrichment or unfair competition, as in California's Business & Professions Code § 17200, which prohibits any "unfair or fraudulent business act or practice and unfair, deceptive, untrue or misleading advertising".

The system was also able to track the target in full-passive automated PNS (ПHC) mode based on the data provided by "Long Track" mobile EWR via radio datalink.

In 3M mode (3m aka three-point) the krug track on jamming signal emitting container (e.g., AN/ALQ-99).

The Cowan–Reines neutrino experiment was conducted by Washington University in St. Louis alumnus Clyde L. Cowan and Stevens Institute of Technology and New York University alumnus Frederick Reines in 1956. The experiment confirmed the existence of neutrinos. Neutrinos, subatomic particles with no electric charge and very small mass, had been conjectured to be an essential particle in beta decay processes in the 1930s. With neither mass nor charge, such particles appeared to be impossible to detect.

The large sizes and low binding energies of Rydberg atoms lead to a high magnetic susceptibility, \chi. As diamagnetic effects scale with the area of the orbit and the area is proportional to the radius squared (A ∝ n4), effects impossible to detect in ground state atoms become obvious in Rydberg atoms, which demonstrate very large diamagnetic shifts. Rydberg atoms exhibit strong electric-dipole coupling of the atoms to electromagnetic fields and has been used to detect radio communications.

Even though the developmental process requires a significant period of work and several research animals, the analysis is rapidly performed and interpreted. However, there are several limitations associated with ELISA for HCP analysis. The HCP quantification relies mainly on the quantity and affinity of anti-HCP antibodies for detection of the HCP antigens. Anti-HCP antibody pools cannot cover the entire HCP population and weakly immunogenic proteins are impossible to detect, since equivalent antibodies are not generated in the process.

Because there are no files on the system, there are no executable files for antivirus and forensic tools to analyze, making such malware nearly impossible to detect. The only way to detect fileless malware is to catch it operating in real time. Recently these type attacks have become more frequent with a 432% increase in 2017 and makeup 35% of the attacks in 2018. Such attacks are not easy to perform but are becoming more prevalent with the help of exploit-kits.

However, plasma stealth implies a substantial reduction of an aircraft's RCS, making it more difficult (but not necessarily impossible) to detect. The mere fact of detection of an aircraft by a radar does not guarantee an accurate targeting solution needed to intercept the aircraft or to engage it with missiles. A reduction in RCS also results in a proportional reduction in detection range, allowing an aircraft to get closer to the radar before being detected. The central issue here is frequency of the incoming signal.

Afterwards, Dr. Eckener ordered section chiefs to inspect the airship during flight. However, the complexity of the airship's structure would make it virtually impossible to detect all weaknesses in the structure. In March 1936, the Hindenburg and the Graf Zeppelin made three-day flights to drop leaflets and broadcast speeches via loudspeaker. Before the airship's takeoff on March 26, 1936, Ernst Lehmann chose to launch the Hindenburg with the wind blowing from behind the airship, instead of into the wind as per standard procedure.

Unscrupulous smugglers are attempting to steal the "Magic Muffler," a device that can make an aircraft practically silent. Flying at night would make the smugglers and their forays across the border, impossible to detect. The smugglers led by rancher Paul Murdock (Earl Metcalfe), capture the inventor, Professor Payson (Josef Swickard), holding him hostage until they get the secrets to his invention. Unable to get Payson to make another device, the gang then kidnaps Professor Payson's daughter (Shirley Palmer) to force her father to work for them.

The level of interference is a function of the signal processors used within the radar, the speed of the aircraft and the relative orientation of wind turbines/aircraft with respect to the radar. An aircraft flying above the wind farm's turning blades could become impossible to detect because the blade tips can be moving at nearly aircraft velocity. Studies are currently being performed to determine the level of this interference and will be used in future site planning. Issues include masking (shadowing), clutter (noise), and signal alteration.

She is capable of using psychological warfare, intimidation, and mistruths to con other people into obeying her. She also has the ability to lie easily without causing any change in her breathing and heartrate (an indication of her psychopathy), making it nearly impossible to detect if she's lying, which she demonstrated in "The Day of Black Sun." She is also an accomplished strategist, as she was able to conquer Ba Sing Se, a city thought to be impenetrable, while usurping the Earth King and hierarchy of the Earth Kingdom capital all in one swift move.

However, the characteristic broad Hα emission line has rarely, if ever, disappeared. The origin of the differences between Type I and Type II Seyfert galaxies is not known yet. There are a few cases where galaxies have been identified as Type II only because the broad components of the spectral lines have been very hard to detect. It is believed by some that all Type II Seyferts are in fact Type I, where the broad components of the lines are impossible to detect because of the angle we are at with respect to the galaxy.

They are typically made of fiberglass, powered by a 225–260 kW diesel engine and manned by a crew of four. They have enough cargo space to carry two to ten tons of cocaine, carry large fuel tanks which give them a range of , and are equipped with satellite navigation systems. There is no head (toilet), and accommodation is cramped. Because much of its structure is fiberglass and it travels barely under the surface, the vessel is nearly impossible to detect via sonar or radar, and very difficult to spot visually.

Architect of the Capitol et al, Compilation of Works of Art and Other Objects in the United States Capitol. 1965 The fragile full-scale plaster model, needed to be separated again into its five main sections to move it from the old House Chamber to Mills' foundry for casting. According to Mills' son Fisk, the Italian artisan refused to dismantle it until he got a major raise and a long-term contract. He had covered the seams of the sections with a layer of plaster that made them impossible to detect.

Philippe Dupuy (born December 12, 1960, Sainte-Adresse) and Charles Berbérian (born May 28, 1959, Baghdad) are French cartoonists most famous for their series of Franco-Belgian comics albums featuring the character Monsieur Jean. Their collaboration is notable as they share every aspect of creating their stories, from plot through layouts, pencils and inks, to the extent that it is impossible to detect who is responsible for what. But in 2003, they decided to again work on their own, and have since published solo material like Hanté by Dupuy in 2005.

The second fault location technique will be taken somewhat out of turn, as it was used to characterize this failure after the SQUID analysis, as an evaluation sample for an equipment vendor. The ability to focus and resolve low-power x-rays and detect their presence or absence has improved to the point that radiography can now be used to identify features heretofore impossible to detect. The equipment at Xradia was used to inspect the failure of interest in this analysis. An example of their findings is shown in Figure 2.

Much of the English Willow cricket bat market consists of bats which are actually made in India from imported English willow blanks. It would be virtually impossible to detect "counterfeit" English willow bats made from Kashmir willow. The marketing of English willow bats is therefore a trust exercise between the buyer and the brand, that the brand has not inflated their supply of "English willow" bats by sourcing blanks from India as well as England. This risk of substitution is a major hurdle for small brands looking to get bats manufactured in India.

Clear-air turbulence is usually impossible to detect with the naked eye and very difficult to detect with a conventional radar,John J. Hicks, Isadore Katz, Claude R. Landry, and Kenneth R. Hardy, "Clear-Air Turbulence: Simultaneous Observations by Radar and Aircraft" Science Science 18 August 1967:Vol. 157. no. 3790, pp. 808-809 with the result that it is difficult for aircraft pilots to detect and avoid it. However, it can be remotely detected with instruments that can measure turbulence with optical techniques, such as scintillometers, Doppler LIDARs, or N-slit interferometers.

The earliest preliminary IDS concept was delineated in 1980 by James Anderson at the National Security Agency and consisted of a set of tools intended to help administrators review audit trails.Anderson, James P., "Computer Security Threat Monitoring and Surveillance," Washing, PA, James P. Anderson Co., 1980. User access logs, file access logs, and system event logs are examples of audit trails. Fred Cohen noted in 1987 that it is impossible to detect an intrusion in every case, and that the resources needed to detect intrusions grow with the amount of usage.

A chimera is an ordinary person or animal except that some of their parts actually came from their twin or from the mother. A chimera may arise either from monozygotic twin fetuses (where it would be impossible to detect), or from dizygotic fetuses, which can be identified by chromosomal comparisons from various parts of the body. The number of cells derived from each fetus can vary from one part of the body to another, and often leads to characteristic mosaicism skin coloration in human chimeras. A chimera may be intersex, composed of cells from a male twin and a female twin.

For example, determining whether a cloud in the distance is harmless or an aerosol of enemy chemical or biological warfare is very difficult to assess quickly. However, with the new metamaterials being developed, the ability exists to see things smaller than the wavelength of light – something which has yet to be achieved in the far field. Utilizing metamaterials in the creation of a new lens may allow soldiers to be able to see pathogens and viruses that are impossible to detect with any visual device. Harnessing subwavelength capabilities then allow for other advancements which appear to be beyond the battlefield.

Transmission electron microscopy (TEM) uses electrons to generate high-resolution images as using electrons allows to overcome limitations of visible light wavelengths. TEM on graphene should be done with electron energy less than 80 keV to induce a smaller amount of defects, because this energy is the threshold electron energy for damaging a single-wall carbon nano-tube. There are some other difficulties in the study of graphene by TEM, e.g., in a plane-view geometry (top-view graphene) the substrate causes strong electron scattering, and a thick substrate makes it impossible to detect the graphene layer.

A number of difficulties present themselves, not least that there is no surviving work confidently attributed to Hubert, and it is thus impossible to detect his style. Instead, art historians compare individual passages to known works by Jan, looking for stylistic differences that might indicate the work of another hand. Advances in dendrochronology have for example established that parts of the wing panels were felled around 1421. Allowing a seasoning time of at least 10 years, we must assume a completion date well after Hubert's death in 1426, thus ruling out his hand from large portions of the wings.

Dudley, William 2004 These adoptive parents create a demand for healthy infants that will be able to assimilate into their new home and cut off ties to their birthplace and culture of origin.Minh, Kevin 2004 Prospective adoptive parents are placed with the "orphans" through adoption agencies, brokers, or advertising agencies online.Masnerus, Laura 1998 Due to the fact that most of the children adopted overseas are so young, they will not have any memories of their birth families. Without a paper trail and without any input from the child, it makes it near impossible to detect whether a child is truly an orphan.

The cooling system was made by Delphi Automotive, a former Harrison Radiator Division of General Motors. This was a bold step for Apple, and should have allowed the use of very fast processors, giving Apple an advantage in both the performance and reliability race, but the system turned out to be subject to coolant leakage. If not caught in time, the leakage could destroy the processors, logic board, and even corrode the aluminium casing itself. While leakage was sometimes detectable by drops of green coolant in or beneath the machine, in many machines the seepage is so slight that it was almost impossible to detect without dismantling the entire computer.

Video simulation showing the warping of space-time and gravitational waves produced, during the final inspiral, merge, and ringdown of black hole binary system GW150914. Albert Einstein originally predicted the existence of gravitational waves in 1916, on the basis of his theory of general relativity. General relativity interprets gravity as a consequence of distortions in space-time, caused by mass. Therefore, Einstein also predicted that events in the cosmos would cause "ripples" in space-time – distortions of space-time itself – which would spread outward, although they would be so minuscule that they would be nearly impossible to detect by any technology foreseen at that time.

Typical direction of tails during a comet's orbit near the Sun In the outer Solar System, comets remain frozen and inactive and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from observations by the Hubble Space Telescope but these detections have been questioned. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas each form their own distinct tail, pointing in slightly different directions.

This is most noticeable in photographs of the model where in many cases is it almost impossible to detect that you are looking at a model, as opposed to the real thing. The disadvantages of near to scale flanges and flangeway crossings are that the trackwork has to be laid and built to very close tolerances and needs to be flat. If this is not the case then the reliability of rolling stock on the trackwork is compromised leading to poor running and derailments. This problem can, to an extent, be mitigated by the use of some form of suspension system in the locomotives and rolling stock used on the layout.

Another possibility is for the Higgs to split into a pair of massive gauge bosons. The most likely possibility is for the Higgs to decay into a pair of W bosons (the light blue line in the plot), which happens about 21.5% of the time for a Higgs boson with a mass of . The W bosons can subsequently decay either into a quark and an antiquark or into a charged lepton and a neutrino. The decays of W bosons into quarks are difficult to distinguish from the background, and the decays into leptons cannot be fully reconstructed (because neutrinos are impossible to detect in particle collision experiments).

These are impossible to detect unless the airport has high- sensitivity X-Ray equipment, as a liquid mixture of water and the drug will most likely not be detected using a standard X-Ray machine. Most of the major airports in Europe, Canada, and the US have the more sensitive machines. In most cases, it is only necessary to wait for the packets to pass normally, but if a packet ruptures or if there is intestinal obstruction, then it may be necessary to operate and surgically remove the packets. Oil-based laxatives should never be used, as they can weaken the latex of condoms and cause packets to rupture.

The mean generation time is equal to the sum of the mean latent period and one-half of the mean infectious period, given that infectiousness is evenly distributed across the infectious period. Since the precise moment of infection is very difficult and almost impossible to detect, the generation time is not properly observable for two successive hosts. Generally, in infectious disease statistics, the onset of clinical symptoms for all the hosts are reported. For two successive generations (or cases or hosts) in a chain of infection, the serial interval is defined as the period of time between the onset of clinical symptoms in the first host and the onset of analogous clinical symptoms in the second host.

While the presence of any mass bends the path of light passing near it, this effect rarely produces the giant arcs and multiple images associated with strong gravitational lensing. Most lines of sight in the universe are thoroughly in the weak lensing regime, in which the deflection is impossible to detect in a single background source. However, even in these cases, the presence of the foreground mass can be detected, by way of a systematic alignment of background sources around the lensing mass. Weak gravitational lensing is thus an intrinsically statistical measurement, but it provides a way to measure the masses of astronomical objects without requiring assumptions about their composition or dynamical state.

A specialist in diabetes told the Inquiry it was almost impossible to detect diabetes in a person who wished to withhold it. The inquiry also received evidence that a friend had asked Spence about his diabetes in relation to his employment as a pilot. Spence had asked his friend to keep it quiet so his employment would not be jeopardised."Judge's View On Hobart Air Crash" The Argus – 16 May 1946, p.6 (National Library of Australia) Retrieved 24 September 2011"Diabetes May Have Contributed To Plane Crash" The Canberra Times – 16 May 1946, p.3 (National Library of Australia) Retrieved 24 September 2011 The senior route captain for Australian National Airways, Captain Douglas Way, told the inquiry he was unaware Spence was treating himself with insulin.

In 1895Poincaré (1895)Katzir (2005), 275–288 Poincaré argued that experiments like that of Michelson–Morley show that it seems to be impossible to detect the absolute motion of matter or the relative motion of matter in relation to the aether. And although most physicists had other views, Poincaré in 1900Poincaré (1900a); Poincaré (1902), Ch. 9–10 stood to his opinion and alternately used the expressions "principle of relative motion" and "relativity of space". He criticized Lorentz by saying, that it would be better to create a more fundamental theory, which explains the absence of any aether drift, than to create one hypothesis after the other. In 1902Poincaré (1902), Ch. 13 he used for the first time the expression "principle of relativity".

The development of flexible dye packs makes it virtually impossible to detect by persons handling the stack. When the marked stack of bills is not used, it is stored next to a magnetic plate near a bank cashier, in standby or safe mode, ready to be handed over to a bank robber by a bank employee. When it is removed from the magnetic plate, the pack is armed. Once it leaves the building and passes through the door frame, a radio transmitter located at the door triggers a timer (typically at least 10 seconds), after which the dye pack explosively releases an aerosol (usually of Disperse Red 9) and sometimes tear gas, intended to destroy the stolen money and mark the robber's body with a bright stain.

Extensive searches for dark matter particles have so far shown no well-agreed detection; the dark energy may be almost impossible to detect in a laboratory, and its value is unnaturally small compared to naive theoretical predictions. Comparison of the model with observations is very successful on large scales (larger than galaxies, up to the observable horizon), but may have some problems on sub-galaxy scales, possibly predicting too many dwarf galaxies and too much dark matter in the innermost regions of galaxies. This problem is called the "small scale crisis". These small scales are harder to resolve in computer simulations, so it is not yet clear whether the problem is the simulations, non-standard properties of dark matter, or a more radical error in the model.

The book's namesake comes from the scientific confusion over how ordinary matter makes up only four percent of the mass-energy in the universe, with the rest consisting of mysterious dark matter and dark energy that are both invisible and almost impossible to detect. It is due to dark matter that galaxies are able to keep their shape, with the mass of dark matter creating enough gravitational force to hold the stars that make up a galaxy together. Dark energy, however, is a substance or force responsible for the accelerating expansion of the universe over time. The significant focus of The 4 Percent Universe is on the developments of astronomical science in the 20th century, including the formation of the expanding universe theory by Edwin Hubble in the 1930s.

This was achieved by using calf skin produced north of the Alps which was able to be processed on both sides, whilst retaining its white colouring and quality, which is a signature of most Paris Bibles. It was impossible to detect the hair side from the flesh side on this vellum, making it an ideal parchment for the fine writing required on these smaller bibles. The reduction in thickness of the vellum also required bookbinders to introduce senions (no link need an explanation) rather than quarternions so that leaves did not come loose from the bound spine due to them being so thin. Due to vast number of leaves in these larger codices tracking systems had to be introduced to allow the bookbinder and illustrators to keep track of the leaves in a quire.

A comet's orbit showing the different directions of the gas and dust tails as the comet passes the Sun In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from the Hubble Space Telescope observations, but these detections have been questioned, and have not yet been independently confirmed. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous tail to form, which points away from the Sun.

Two Frenchmen serving in the SOE, Raymond Basset (codename Mary) and André Jarrot (codename Goujean), were parachuted in and were able to repeatedly sabotage the local power grid to sharply lower production at the Schneider-Creusot works. Freney, who had emerged as a leading résistant, recruited the engineer Henri Garnier living in Toulouse to teach French workers at factories producing weapons for the Wehrmacht how best to drastically shorten the lifespan of the Wehrmacht's weapons, usually by making deviations of a few millimetres, which increased strain on the weapons; such acts of quiet sabotage were almost impossible to detect, which meant no French people would be shot in reprisal. To maintain contact with Britain, Resistance leaders crossed the English Channel at night on a boat, made their way via Spain and Portugal, or took a "spy taxi", as the British Lysander aircraft were known in France, which landed on secret airfields at night. More commonly, contact with Britain was maintained via radio.

One former U.S. official who worked with micro-UAVs said that they can be almost impossible to detect at night. "It can be outside your window and you won't hear a whisper," the official said.Warrick, Joby, and Peter Finn, Amid outrage over civilian deaths in Pakistan, CIA turns to smaller missiles , The Washington Post, 26 April 2010 The drone operators also have changed to trying to target insurgents in vehicles rather than residences to reduce the chances of civilian casualties. An oft-quoted 2010 study by Peter Bergen and Katherine Tiedemann at the New America Foundation went as follows: "Our study shows that the 265 reported drone strikes in Northwest Pakistan, including 52 in 2011, from 2004 to the present, have killed approximately between 1,628 and 2,561 individuals, of whom around 1,335 to 2,090 were described as militants in reliable press accounts. Thus, the true non-militant fatality rate since 2004 according to our analysis is approximately 20 percent. Prior to 2010 it was 5 percent." In a separate report, written by Bergen in 2012, he commented that civilian casualties continued to fall even as drone strikes increased, concluding that "Today, for the first time, the estimated civilian death rate is close to zero."WILLIAMS, BRIAN GLYN.
