Since the absorption of radio waves in rocklike material varies with wave length, it should be possible to sample the temperature variation at different depths beneath the surface and possibly detect changes in the structure or composition of the lunar surface material.

Since 1996 estimates, there has been a significant reduction in the total length of unpaved highway in Botswana-between 1996 and 1999 total length of unpaved highway fell from 14, 139 km to 4, 597 km.

Since the desired effect is computational difficulty, in theory one would choose an algorithm and desired difficulty level, thus decide the key length accordingly.

The proof of this fact relies on an algorithm which, given the first n digits of Ω, solves Turing's halting problem for programs of length up to n. Since the halting problem is undecidable, Ω can not be computed.

Since the compression ratio is the ratio between dynamic and static volumes of the combustion chamber the Atkinson cycle's method of increasing the length of the powerstroke compared to the intake stroke ultimately altered the compression ratio at different stages of the cycle.

Since work is defined as a force acting through a distance ( a length of space ), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

Since the stored energy in the barrier is less than the energy stored in a barrier-free region of the same length due to destructive interference, the group delay for the energy to escape the barrier region is shorter than it would be in free space, which according to Winful is the explanation for apparently superluminal tunneling.

Since 1983, it has been defined as " the length of the path travelled by light in vacuum during a time interval of of a second.

Since rifles were used by sharpshooters who didn't routinely fire over other men ’ s shoulders, long length was not required to avoid the forward line.

Since then, changes to the line length have been a relatively common variant, such that Stephen Burt has written: " sestinas, as the form exists today, not require expertise with inherited meter …".

Since the most common trailer used in the U. S. is 53 feet ( 16 m ) in length, the difference in freight capacity between cab-over and conventional cab tractor / trailer combinations is negligible.

Since all matter and energy gravitate, gravity's effects are cumulative ; by contrast, the effects of positive and negative charges tend to cancel one another, making electromagnetism relatively insignificant on cosmological length scales.

Since the end of the series rumors have circulated that a feature length movie was in the works.

Since the path length varies, generally, so will the phases of the waves at that point from each of the slits, and thus will add or subtract from one another to create peaks and valleys, through the phenomenon of additive and destructive interference.

Since the E field is uniform in the direction of wire length, for a conductor having uniformly consistent resistivity ρ, the current density J will also be uniform in any cross-sectional area and oriented in the direction of wire length, so we may write:

Since the real numbers can be used to represent points along an infinitely long line, this implies that a line segment of length 1, which is a part of that line, has the same number of points as the whole line.

Since the focal length f of a lens is dependent on the refractive index n, different wavelengths of light will be focused on different positions.

Since longitudinal waves have a much greater phase velocity than transverse waves, V < sub > long </ sub > is much greater than V < sub > trans </ sub >, and the relaxation length or mean free path of longitudinal phonons will be much greater.

Since fluidity of the surfactant mixture is also dependent on fatty acid tail length where length leads to increased surfactant fluidity, the change in tail length may indicate a surfactant system adaptation in response to the selection for an effective antiadhesive surfactant in collapsed lungs of diving pinnipeds.

Since the sound waves propagate, not from a single point source, but along the length of the lightning's path, the sound origin's varying distances from the observer can generate a rolling or rumbling effect.

Since the surfaces of a wet clutch can be slippery ( as with a motorcycle clutch bathed in engine oil ), stacking multiple clutch discs can compensate for the lower coefficient of friction and so eliminate slippage under power when fully engaged.

Since the weight of the engine was so much less than on piston engined fighters, having two engines was no longer a handicap and one or two were used, depending on requirements.

Since the heat source that supplies thermal energy to the engine can thus be powered by virtually any kind of energy, heat engines are very versatile and have a wide range of applicability.

Since very few actual implementations of heat engines exactly match their underlying thermodynamic cycles, one could say that a thermodynamic cycle is an ideal case of a mechanical engine.

Since Id Software revealed their engine Id Tech 5, they call their engines " Id Tech ", followed by a version number.

Since 2001, trim levels are also indicated by including a number after the main index: '- 00 ' means base trim level, '- 01 ' means standard trim and '- 02 ' designates deluxe version ; for example, VAZ-21121-02 means Lada 112 hatchback with an 1. 6L SOHC engine and deluxe trim.

Since the piston is the main reciprocating part of an engine, its movement creates an imbalance.

Since the engine does not have an oil injection system, two-stroke oil has to be added to the fuel tank every time the car was filled up, at a 50: 1 or 33: 1 ratio of fuel to oil.

Since the efficiency of a rocket engine is related to the square root of the temperature of the working fluid, the solid core design needs to be constructed of materials that remain strong at as high a temperature as possible.

Since some Web search engines base the importance of sites on the number of different sites linking to them, referrer-log spam may increase the search engine rankings of the spammer's sites.

Since it provides the graphical elements surrounding the area in which the engine paints documents, the term chrome is sometimes used to refer to it.

Since the mid-1990s, Alenia Aermacchi has participated in programs for the supply of engine nacelles for civil aircraft.

Since the World Sportscar Championship was conceived there have been various regulations regarding bodywork, engine style and size, tyres and aerodynamics to which these cars must be built.

Since it is difficult to know that the rasterization engine will draw all pixels from front to back, there must be some way of ensuring that pixels close to the viewer are not overwritten by pixels far away.

Since the original source code to the game was lost by Rogue Entertainment, game engine recreations of Strife were created by Doom source port developers through reverse engineering, notably by Jānis Legzdiņš ( author of the Doom source port Vavoom ), Randy Heit ( author of ZDoom ), Samuel Villarreal ( author of SvStrife ) and James Haley ( author with Samuel Villareal of Chocolate Strife ).

Since 1976 Hodgkins has been served by the Pleasantview Fire Protection District which had its own humble beginnings with one engine in 1946 and has grown into a top-notch organization since then.

Since the transom may need to be cut down for the engine to fit properly, an engine well should be used to prevent low waves from splashing over the transom and flooding the boat.

Since the pressure on top of the engine is ambient, this means that base gives no overall thrust ( but it also means that this part of the nozzle doesn't lose thrust by forming a partial vacuum, thus the base part of the nozzle can be ignored at low altitude ).

Since fuel is not present in the combustion chamber until virtually the point at which combustion is required to begin, there is no risk of pre-ignition or engine knock.

Since then, improvements in both engine power and armament generally led to a loss of interest in this class for most nations.

Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, allowing those results to be false would turn users to find other search sources.

Since WorldWideWeb was developed on and for the NeXTSTEP platform, the program used many of NeXTSTEP's components – WorldWideWeb's layout engine was built around NeXTSTEP's Text class.

* Since its introduction in 1975, the Honda Goldwing has utilized a boxer engine, a four-cylinder until 1987, and six-cylinders since.

Since then, the inline-four has become one of the most common engine configurations in street bikes.
