	Constant bitrate - Wikipedia, the free encyclopedia
		Constant bit rate (CBR) is a term used in telecommunications, relating to the quality of service.
		When referring to codecs, constant bit rate encoding means that the rate at which a codec's output data should be consumed is constant.
		CBR is useful for streaming multimedia content on limited capacity channels since it is the maximum bit rate that matters, not the average, so CBR would be used to take advantage of all of the capacity.

	Reaction rate - Wikipedia, the free encyclopedia
		The reaction rate for a reactant or product in a particular reaction is defined as the amount of the chemical that is formed or removed (in moles or mass units) per unit time per unit volume.
		For a chemical reaction n A + m B → C + D, the rate equation or rate law is a mathematical expression used in chemical kinetics to link the rate of a reaction to the concentration of each reactant and their various orders.
		In this equation k(T) is the reaction rate coefficient or rate constant, although it is not really a constant, because it includes everything that affects reaction rate outside concentration: mainly temperature but also ionic strength or light irradiation.

	Relativistic Motion Perspective
		The constant time rate measured directly in any inertial frame is equal in magnitude and opposite in direction to the constant time rate measured directly in any other inertial frame.
		The relative time rate in any inertial frame is equal in magnitude and opposite in direction to the relative time rate in any other inertial frame it is compared with.
		Whereas the constant time rate in any inertial frame cannot change without acceleration, the relative time rate in any inertial depends only on the relative motion between it and any other inertial frame that it is compared with.

	Define CBR - Constant Bit Rate
		“Bit rate” is sometimes used interchangeably with “baud rate”, which is correct only when each modulation transition of a data transmission system carries exactly one bit of data (something not true for modern modem modulation systems, for example).
		When using CBR encoding, you specify the target bit rate for a stream, and the codec uses whatever amount of compression is necessary to achieve it.
		With CBR encoding the bit rate and size of the encoded stream are known prior to encoding.

	Reaction rate theory
		Kramers reaction rate theory predicts that the solvent dynamics will always decrease the reaction rate, or that in the most favorable situation no barrier recrossings take place and the rate constant corresponds with that of Rice-Ramsperger-Kassel-Marcus (RRKM) rate theory, which gives the TST rate as a function of the collision rate for independent polyatomic molecules.
		A typical appearance of the rate constant as a function of time is shown in figure 2.1.
		By separating the rate constant in terms of the probability to reach the barrier top, the crossing velocity and the transmission coefficient, solvent effects on the reaction rate constant can be studied with molecular dynamics techniques.

	Upscaled effective rate constant for heterogeneous reactions
		An effective rate constant for the mean field approximation describing the change in mean concentration with time is derived.
		The effective rate constant decreases with increasing time eventually approaching zero as the system approaches equilibrium.
		This behavior suggests that a possible explanation for the observed discrepancy between laboratory measured rate constants on uniform grain sizes and field measurements may in part be caused by the heterogeneous distribution of grain sizes in natural systems.

	What is a rate constant? (Site not responding. Last check: 2007-11-01)
		A rate constant is an extremely useful quantitative characteristic of a chemical or physical process.
		and is (apart from a volume factor) equal to the rate constant of the process catalyzed by the enzyme.
		When our analysis of the data reveals that a rate constant has changed in some experimental circumstance, we have the best possible evidence of a biologically significant regulatory change in the corresponding process.

		The particular interest rate level chosen is the one which is consistent with having the inflation forecast h periods ahead on target.

		In addition, it must constrain the number of bits in each access unit so that when it is inserted into the encoder buffer, there is enough time for it to be transmitted before its DTS/PTS time.
		Each access unit is reduced if necessary to a size that fits between the end of the previous access unit and the data position in the buffer that will be transmitted before the next DTS/PTS time.
		In the case of a practical non-instantaneous encoder (or decoder), additional buffer space equal to one picture period times the constant bit rate may be required.

		After correcting for a statistical error, the Labor Department's Bureau of Labor Statistics now says that the rate of layoffs in the workforce in the middle of the decade remained roughly the same as in the early 1990s.
		The original report appeared to show that both the rate and numbers of layoffs had declined in the past few years.
		While the Clinton administration seized the original numbers to claim that the worst of the layoffs had passed, the Chairman of his Council of Economic Advisers, Joseph E. Stiglitz, responded to the less favorable new numbers by challenging their statistical validity.
