Its variety of tempo and texture, perhaps going against Ms. LeCrone's proclivities, prompted her to build up a larger force despite her customary attenuations.

In the end, the evolved avians decide to retroactively remove the time travel science from human hands, thereby rendering all of the events up to that point irrelevant. But, out of the ashes of this paradox, its tangles and attenuations mercifully forgotten, a love of the world is retained – a deep unselfish love of learning the world and all its creatures.

Each of these bounces can introduce phase shifts, time delays, attenuations, and even distortions that can destructively interfere with one another at the aperture of the receiving antenna. Antenna diversity is especially effective at mitigating these multipath propagation situations. This is because multiple antennas afford a receiver several observations of the same signal. Each antenna will experience a different interference environment.

Mobile radio communication performance is significantly affected by the radio propagation environment. Blocking by buildings and natural obstacles creates multiple paths between the transmitter and the receiver, with different time variances, phases and attenuations. In a single-input, single-output (SISO) system, multiple propagation paths can create problems for signal optimization. However, based on the development of multiple input, multiple output (MIMO) systems, it can enhance channel capacity and improve QoS.

Studies show seismic wave reflection between an elastic overburden and an equivalent medium have coefficients of reflection that vary with frequency. This variation, depends on the behavior of AVO at the interface. The calculation of synthetic seismographs for the ideal model is carried out using the reflectivity technique for those materials whose velocities and attenuations are frequency dependent. This is usually used since the effects of velocity and attenuation variations are detectable on stacked data.

This is a complex provision that, in practice, attempts to ban the participation of all persons below age 18 in any kind of scene of a pornographic nature. The standard penalty for any of these actions is imprisonment for a period between one and five years. This standard penalty is subject to a number of aggravations and attenuations, however, depending on the circumstances.See section 177 of the Portuguese Criminal Code This section of the Criminal Code has raised severe controversy.

In the fall of 1970, the company announced that researchers Robert D. Maurer, Donald Keck, Peter C. Schultz, and Frank Zimar had demonstrated an optical fiber with a low optical attenuation of 17 dB per kilometer by doping silica glass with titanium. A few years later they produced a fiber with only 4 dB/km, using germanium oxide as the core dopant. Such low attenuations made fiber optics practical for telecommunications and networking. Corning became the world's leading manufacturer of optical fiber.

In 2013, reviewing the photometric data obtained in October 2005, Brian Warner found evidence that Tchantchès is possibly an asynchronous binary asteroid. Attenuations seen in the revised lightcurve indicated mutual occultations and eclipses events caused by a minor-planet moon orbiting Tchantchès. The satellite has an orbital period of 15.35 hours (2014 publication), and diameter of at least 25% of that of its primary. The Johnston's archive derives a satellite diameter of 510 meters and estimates a semi-major axis of 3.8 kilometers for its orbit.

In telecommunication, magneto-ionic double refraction is the combined effect of the Earth's magnetic field and atmospheric ionization, whereby a linearly polarized wave entering the ionosphere is split into two components called the ordinary wave and extraordinary wave. The component waves follow different paths, experience different attenuations, have different phase velocities, and, in general, are elliptically polarized in opposite senses. The critical frequency of the extraordinary wave is always greater than the critical frequency of the ordinary wave (i.e. the wave in absence of the magnetic field) by the amount approximately equal to .

Telephone exchange with later antennas mounted higher for antifade Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments, there is no clear line-of-sight (LOS) between transmitter and receiver. Instead the signal is reflected along multiple paths before finally being received. Each of these bounces can introduce phase shifts, time delays, attenuations, and distortions that can destructively interfere with one another at the aperture of the receiving antenna.

During the first of the two a photometric observations – a collaboration between Czech astronomers Petr Pravec, Peter Kušnirák, Leonard Kornoš and Jozef Világi at Ondřejov Observatory, as well as American astronomers Donald Pray, Russel Durkee, Walter R. Cooney Jr., John Gross and Dirk Terrell at several locations in the United States – it was revealed, that Kastels lightcurve consisted of two linearly additive components, indicative for the presence of an asteroid moon. However, no attenuations were observed, which typically occur when the primary and secondary body are eclipsing each other. After a second observation in 2014, the binary nature of Kastel still remains uncertain. The "Johnstonsarchive" gives no estimates.
