  MURI: Mechanisms of Fluid-Mud Interactions Under Waves
Indirect wave interactions: the fluid mud motion is forced by nonlinear effects of the surface wave-wave interactions.
The wave tank is rather wide: 2.5 m, with a length of 18.3 m and a depth of 1.7 m.
Indirect wave interactions: We consider the general nonlinear problem of surface wave-wave interactions and their direct coupling with the mud flow.

 Tone generator system for an electronic organ - Patent 4173916
An indirect keying circuit as defined by claim 1 wherein the voltage signal source applied to the gate of said first transistor is an A.C. voltage signal having a predetermined waveform, the output analog signal at said output terminal being amplitude modulated in accordance with said A.C. voltage signal.
In a prior art indirect keying circuit, however, since the linearity of the transfer characteristic was poor and the dynamic range was not sufficiently wide, the signal wave to be handled was mainly a square wave although analog signal switching and envelope control were effected.
When the square wave signal is used as the input signal, the output waveform is a staircase wave when the number of stages of the frequency division is large, and a frequency spectrum close to that of a saw-tooth wave is produced.

 Climate Change 2001: The Scientific Basis
The physics and chemistry of the indirect effect of aerosols is discussed in detail in Chapter 5.
The forcing estimates for the first indirect effect from sulphate aerosols range from -0.3 to -1.8 Wm, which is close to the range of 0 to -1.5 Wm given in the SAR when only a few estimates were available.
In studies indicated by an asterisk, the estimate in flux change due to the indirect effect of aerosols was computed as the difference in top of atmosphere fluxes between two distinct simulations and therefore does not represent a forcing in the strict sense (see text).

 shockwaves - scientific
The shock wave is then reflected from the inside wall of a metal ellipsoid to create a focal point of shock wave energy in the target tissue.
Meanwhile, the generation of transient cavitation bubbles and their collapse during the tensile phase of a shock wave are known as "indirect shock wave effects".
It is theorized that direct shock wave effects and indirect (cavitation) effects cause hematoma and some cell death which are responsible for the stimulation of new bone formation.

 THE SOURCE MECHANISM OF THE EARTHQUAKE AND TSUNAMI OF OCTOBER 17, 1966 IN PERU - Dr. George Pararas-Carayannis
The leading tsunami waves are generated from the periphery of this area and their arrival at nearby stations is indicative of the initial ocean floor displacement.
Considering that the waves reaching the immediate coastline had amplitudes of about 3 meters, the shoaling and resonance amplification factor on the coast for local tsunamis, for these particular localities, is estimated to be three times the deep water value.
Waves were refracted toward the earthquake area from each station for lengths of time equal to the tsunami travel time for that station, using the long wave velocity approximation c = Square root of (gd), where c is velocity, g is gravity, and d is depth.

 Measuring Wave Front Phases Using a Thin Birefrigent Crystal   (Site not responding. Last check: 2007-10-02)
Waves are characterized by their amplitude, frequency, polarization, and phase.
Wave fronts have constant phase and the local propagation directions are the normal vectors on the surfaces of the wave fronts.
An object wave passes through a thick birefringent crystal with an analyzer behind it to superimpose the ordinary and extraordinary waves that come out of the crystal.

 MIROS AS - Wave Monitoring By Use Of Wave Radars
A typical case is wave measurements from an offshore platform in deep waters with the presence of high currents making the mooring of a wave buoy enormously difficult.
Indirect sensors observe the surface waves via the interaction with some other physical process as for example the radar cross section of the sea surface.
Additional measurement of the non-directional wave spectrum may be required for calibration purposes or an empirical method of calibration, relating some parameter derived from the measured data to the real wave height, may be employed.

 ISMST- International Society for Musculoskeletal Shockwave Therapy
The mechanism of the shock wave for orthopedic diseases is under investigation, it's not clear at the moment, which effect is dominant, or whether it is a combination of direct and indirect shock wave effect.
This means electrohydraulic shock wave devices generated shock waves in a large focus volume whereas electromagnetic shock wave devices have a real shock wave only in the focus center and in a small area around the center.
As it was discussed in the section "Effects of shock waves" the positive pressure amplitude is responsible for the direct and the tensile wave is responsible for the indirect shock wave effect.

 WAVE
WAVE was also inconsistent in the methods used to propose indirect cost rates and to allocate indirect costs to its programs.
WAVE charged all of its costs to all other projects during the year and, at year end, "allocated" (transferred) to the Partnership grant the deficits of various cost centers whose activities, according to WAVE, were within the scope of the Partnership grant.
WAVE transferred the deficits to the Partnership grant in a manner that the amounts transferred agreed with the grant budget by line item and by total.

 American Antitrust Institute - Activities   (Site not responding. Last check: 2007-10-02)
The burgeoning current wave of indirect purchaser antitrust suits filed in state courts is the second development that has brought renewed interest to the scope of diversity jurisdiction in class actions - by defendants seeking to remove indirect purchaser actions to federal court.
Because indirect purchaser suits do not arise under federal law, they do not present federal questions (unless they are viewed as "truly federal under the fading "artful pleading doctrine").
Indirect purchaser suits are removable to federal courts only in those circuits like the Fifth, which view Zahn as having been effectively overruled.

 [No title]
As I mentioned earlier, the indirect wave is delayed and we’ll model the delay by Tau.
After the indirect wave is attenuated and delayed, it gets added to the direct wave, and the receiver gets the sum of the waves.
This plot is for an alpha ratio of 3, which means that the indirect wave is 1/3 as strong as the direct wave.

The rest of the sound, over 99.8% of it, the "indirect sound", misses the ears and continues on, crashing into the walls, floor and carpet, the people, coats, and chairs, the roof and its beams, the walls, windows and doors.
The amount of indirect sound that is reflected depends on the acoustic nature of the reflecting surface.
The indirect sound remains in the hall reflecting off of one surface after another, remaining audible to the listeners until it finally disappears, having been absorbed and leaked out of the room.

The time (or equivalent distance) displacement of some characteristic of a wave relative to the same characteristic of a reference wave; that is, the difference in phase between the two waves.
A radio wave which travels directly from the transmitting antenna to the receiving antenna, in contrast with an indirect wave, which undergoes an abrupt change of direction by refraction or reflection.
A medium in which the phase velocity of a wave, either electromagnetic or hydromagnetic, is a function of the frequency.

 Chapter One:
Basic Wave Physics For Sizing Methods
This indirect shearwave strikes the ID surface and mode converts to a longitudinal wave that moves or "creeps" along the ID surface.
This is due to the spherical wave radiating from the tip of the flaw and reflecting off the ID surface and returning at a later time beyond the corner trap signal.
Shear waves may be used if the coarse grain structure of the base material or the weld metal does not impede the transmission of the sound energy.

 SPACE.com -- Detecting Other Worlds: The Wobble Method
Since the train is moving toward you, each subsequent sound wave being emitted has less and less distance to travel to you.
This means that, according to your watch, the frequency of the waves arrival times increases (according to the engineers watch, the frequency remains the same).
Scientists break light waves up into their component colors, and if you examine the rainbow colors of the Sun (called the "solar spectrum") with a prism, you'll notice dark lines within the spectrum where color is almost completely missing.

 U.S. Scientists Study Ecosystem Damage from Tsunami - US Department of State
The battering waves, the upheaval of sediment and the tide of debris that resulted from the Indian Ocean tsunami might have caused extensive environmental damage to affected coastlines.
The severe wave energy – tons of surging water pounding on the shores – could be one cause of damage for shallow bays and coral reefs.
The direct impact of severe wave energy on shallow nearshore habitats (including coral reef ecosystems, seagrasses and mangroves) could be extensive but also depends on the amount of wave energy these ecosystems are normally exposed to.

 Wave Ultrasonics   (Site not responding. Last check: 2007-10-02)
When the high pressure wave hits the bubble wall, the bubble collapses; it is the energy released by this collapse that will assist a detergent in breaking the bonds between parts and their soils.
Indirect cleaning involves placing the parts to be cleaned in an inner nonperforated tray or beaker that often contains a solution that the user may not want directly filling the ultrasonic tank.
When choosing indirect cleaning, make sure that the water level inside the tank itself is maintained to the fill line (about 1" from the tank top) at all times.

 HeadWize - Technical Paper: Chaotic Waves for 3D Audio by Alastair Sibbald
It is well known that sound wave reflections and reverberation have a great influence on the perceived properties of sounds and that the ratio of direct sound (the wavefront which arrives at the listener by a direct path, without intervening reflection) to reverberant sound is a powerful influence on the perception of soundsource distance.
In reality, the indirect waves that arrive at the listener are turbulent and chaotic in nature; they are not the ideal, discrete events as depicted in Figures 2 and 6.
Clearly, the scattered wave characteristics are dependent on many factors, primarily the size and spatial density of the scattering objects and their relationship to the source and listener.

 Indirect nuclear spin-spin coupling constants   (Site not responding. Last check: 2007-10-02)
As mentioned in the introduction of this chapter, the calculation of indirect nuclear spin-spin coupling constants is a time consuming task due to the large number of contribution to the total spin--spin coupling constants.
This input will calculate the indirect nuclear spin-spin coupling  constants between isotopes with non-zero magnetic moments  and a natural abundance  of more than 1%.
Sometimes the results obtained with a Hartree-Fock wave function may help in predicting the relative importance of the different contributions, thus helping in the decision of which contributions should be calculated at a correlated level [45].

However, for heat waves, the heat and humidity are sometimes labeled as “secondary” or “contributing” causes of death.
These are indirect deaths, which if shown, is the second number in the heat wave column.
Likewise, nearly all deaths attributed to vehicle deaths on highways in Winter Storms are “indirect” deaths, since the driver was driving too fast for the conditions, etc. In other words, the snow or ice did not kill the individual; the death was the result of a vehicle accident.
