Frame rate - Wikipedia, the free encyclopedia Frame rate is most often expressed in frames per second (often abbreviated "fps", but not to be confused with FPS or first-person shooter) or, equivalently, Hertz (Hz). The frame rate is related to but not identical to a physiological concept called the flicker fusion threshold or flicker fusion rate. These rates would be impractical for the actual frame rate of most film mechanisms so the shutter in the projection devices is actually arranged to interrupt the light two or three times for every film frame. en.wikipedia.org /wiki/Frame_rate   (1260 words)

Discount rate - Wikipedia, the free encyclopedia The discount rate is the interest rate that an eligible depository institution (such as a bank) is charged to borrow short term funds directly from the central bank through the discount window. Discount rate normally refers to the interest rate, though in fact a discount rate is slightly different from the interest rate, in terms of how it is calculated. The discount rate is the value used in accounting procedures to determine the present value of future cash flows arising from a project, ie the discounted value of all future cashflows. en.wikipedia.org /wiki/Discount_rate   (535 words)

Heart rate - Wikipedia, the free encyclopedia Heart rate monitors allow accurate measurements to be taken continuously and can be used during exercise when manual measurement would be difficult or impossible (such as when the hands are being used). The pulse rate (which in most people is identical to the heart rate) can be measured at any point on the body where an artery is close to the surface. Target Heart Rate (THR), or Training Heart Rate, is a desired range of heart rate reached during aerobic exercise which enables one's heart and lungs to receive the most benefit from a workout. en.wikipedia.org /wiki/Heart_rate   (1377 words)

Slew rate - Wikipedia, the free encyclopedia In mechanics the slew rate is given in dimensions 1/T and is associated with the change in position over time of an object which orbits around the observer. In electronics, the slew rate is a nonlinear effect in operational amplifiers. The slew-rate of an op-amp is defined as the maximum rate of change of the output voltage for all possible input signals. en.wikipedia.org /wiki/Slew_rate   (291 words)

Interest rate - Wikipedia, the free encyclopedia Interest rates are normally expressed as a percentage over the period of one year. Interest rates are the main determinant of investment on a macroeconomic scale. Interest rates are set by a government institution, usually a central bank, as the main tool of monetary policy. en.wikipedia.org /wiki/Interest_rate   (1383 words)

Fertility rate -- Facts, Info, and Encyclopedia article The (total) (The state of being fertile; capable of producing offspring) fertility rate of a population is the average number of child births per woman. Fertility rates are also higher due to the lack of access to (An agent or device intended to prevent conception) contraceptives. (additional info and facts about Developed countries) Developed countries usually have a much lower fertility rate due to higher living standards and the (A belief in the importance of the individual and the virtue of self-reliance and personal independence) individualism (A particular society at a particular time and place) culture. www.absoluteastronomy.com /encyclopedia/f/fe/fertility_rate.htm   (211 words)

Clock rate - Wikipedia, the free encyclopedia The clock rate is the fundamental rate in cycles per second, measured in hertz, at which a computer performs its most basic operations such as adding two numbers or transferring a value from one processor register to another. Usually when referring to a computer, the term "clock rate" is used to refer to the speed of the CPU. The clock rate of a computer is only useful for providing comparisons between computer chips in the same processor family. en.wikipedia.org /wiki/Clock_rate   (539 words)

Crime rate - Wikipedia, the free encyclopedia Crime rate is a useful statistic for many purposes, such as evaluating the effectiveness of crime prevention measures or the relative safety of a particular city or neighborhood. Crime rate statistics are commonly used by politicians to advocate for or against a policy designed to deal with crime. Crime rate is a measure of the rate of occurrence of crimes committed in a given area and time. en.wikipedia.org /wiki/Crime_rate   (319 words)

Reaction rate - Wikipedia, the free encyclopedia The reaction rate for a reactant or product in a particular reaction is defined as the amount (in moles or mass units) per unit time per unit volume that is formed or removed. Pressure: The rate of gaseous reactions usually increases with an increase in pressure. A catalyst: The presence of a catalyst increases the reaction rate in both the forward and reverse reactions by providing an alternative pathway with a lower activation energy. en.wikipedia.org /wiki/Reaction_rate   (553 words)

Basal metabolic rate -- Facts, Info, and Encyclopedia article Basal metabolic rate (BMR), is the rate of (The organic processes (in a cell or organism) that are necessary for life) metabolism when an individual is at rest in a warm envirnonment and is in the post absorptive state, and have not eaten for at least 12 hours. Basal metabolic rate is measured under very restrictive circumstances. A more common and closely related term used in many cases is resting metabolic rate (RMR), which is measured under less strict conditions. www.absoluteastronomy.com /encyclopedia/b/ba/basal_metabolic_rate.htm   (153 words)

Baud - Wikipedia, the free encyclopedia In telecommunications and electronics, baud (pronounced /bɔːd/) is a measure of the "signaling rate" which is the number of changes to the transmission media per second in a modulated signal. A clear example of the difference between the baud rate (or signalling rate) and the data rate (or bit rate) is a man using a single semaphore flag. Note : Baud rate should not be confused with data rate (also called "bits per second"). en.wikipedia.org /wiki/Baud_rate   (362 words)

Bit rate - Wikipedia, the free encyclopedia When describing bit rates, binary prefixes are almost never used and SI prefixes are almost always used with the standard, decimal meanings, not the computer-oriented binary meanings. In digital multimedia, bit rate is the number of bits used per unit of time to represent a continuous medium such as audio or video. While often referred to as "speed", bit rate does not measure distance/time but quantity/time, and thus should be distinguished from the "propagation speed" (which depends on the transmission medium and has the usual physical meaning). en.wikipedia.org /wiki/Bit_rate   (754 words)

Mortality rate - Wikipedia, the free encyclopedia Mortality rate (the word mortality comes from mortal, which originates from Latin mors, death) is the number of deaths (from a disease or in general) per 1000 people and typically reported on an annual basis. The perinatal mortality rate, the sum of neonatal deaths and fetal deaths (stillbirths) per 1,000 births. The early mortality rate, the total number of deaths in the early stages of an ongoing treatment, or in the period immediatly following an acute treatment. en.wikipedia.org /wiki/Mortality_rate   (444 words)

Flat tax - Wikipedia, the free encyclopedia A flat tax, also called a proportional tax, is a system that taxes all entities in a class (typically either citizens or corporations) at the same rate (as a proportion of income), as opposed to a graduated, or progressive, scheme. The flat tax is not used in many developed countries on a national level, standing in contrast to the more widely used progressive income tax, in which citizens and corporations with higher incomes pay tax at a higher rate than those with lower income. To demonstrate its benefits, proponents of flat tax use as examples the largely former-Communist countries of Eastern Europe that have adopted the system. en.wikipedia.org /wiki/Flat_tax   (3203 words)

Prime rate - Wikipedia, the free encyclopedia The Federal Funds Rate is likewise determined by the Discount Rate, the rate that is actually set by the Federal Open Market Committee (FOMC) in its periodic meetings. The Prime Rate is used often in calculating mortgages and other variable rate loans. The most commonly recognized prime rate index is the Wall Street Journal Prime Rate (WSJ Prime Rate), published in the Wall Street Journal. en.wikipedia.org /wiki/Prime_rate   (295 words)

Heart - Wikipedia, the free encyclopedia Amphibians and reptiles have a three-chambered heart, in which oxygenated blood from the lungs and de-oxygenated blood from the respiring tissues enters by separate atria, and is directed via a spiral valve to the appropriate vessel—aorta for oxygenated blood and pulmonary vein for deoxygenated blood. The heart (Latin cor) is a hollow, muscular organ in vertebrates that pumps blood through the blood vessels by repeated, rhythmic contractions, or a similar structure in annelids, mollusks, and arthropods. In the human body, the heart is normally situated slightly to the left of the middle of the thorax, underneath the sternum (breastbone). en.wikipedia.org /wiki/Heart   (1914 words)

Wage - Wikipedia, the free encyclopedia Depending on the structure and traditions of different economies around the world, wage rates are either primarily market-driven (the USA) or influenced by other factors such as tradition, social structure and seniority, as in Japan. Several countries have enacted a statutory minimum wage rate in an attempt to prevent the (some say supposed) exploitation of low-paid workers. In the United States, wages for most workers are set by market forces, or else by collective bargaining, where a labor union negotiates on workers' behalf. en.wikipedia.org /wiki/Wage_rate   (354 words)

Chemical reaction - Wikipedia, the free encyclopedia Reaction rates are related to the concentrations of substances involved in reactions, as quantified by the law of mass action. Analysis of reaction rates is important for several applications, such as in chemical engineering or in chemical equilibrium study. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions. www.sciencedaily.com /encyclopedia/chemical_reaction   (1538 words)

Pulse - Wikipedia, the free encyclopedia In this case, the heart rate should be determined by auscultation of the heart apex, in which case it is not the pulse. The pulse results from pressure waves moving through the blood vessels, which are pliable; it is not caused by the forward movement of the blood. The pulse deficit (difference between heart beats and pulsations at the periphery) should be determined by simultaneous palpation at the radial artery and auscultation at the heart apex. en.wikipedia.org /wiki/Pulse   (1538 words)

Automatic baud rate detection - Wikipedia, the free encyclopedia Automatic baud rate detection (ABR, autobaud) means process by which a receiving device (such as a modem) determines the speed, code level, and stop bits of incoming data by examining the first character, usually a preselected sign-on character. ABR allows the receiving device to accept data from a variety of transmitting devices operating at different speeds without needing to establish data rates in advance. This article was originally based on material from the Free On-line Dictionary of Computing, which is licensed under the GFDL. en.wikipedia.org /wiki/Automatic_baud_rate_detection   (129 words)

2nd mortgage rate It is usually used to buy the home although it is becoming more popular to consider a new 2nd mortgage rate, where the propety is already owned, to access a more competitive 2nd mortgage rate product or to raise capital for other purposes, such as school fees or business investment. 2nd mortgage rate were once the preserve of building societies and the high street banks, however recently far more competition has entered the market and there is now a raft of lenders offering 2nd mortgage rate loans on residential property. However, most 2nd mortgage rates are flexible enough to allow for early repayment or, if your circumstances dictate, the term can be extended beyond the original loan period. www.yardsalethemovie.net /2nd_mortgage_rate.htm   (129 words)

Clock signal - Wikipedia, the free encyclopedia Such sine wave clocks are often differential signals, because this type of signal has twice the slew rate, and therefore half the timing uncertainty, of a single-ended signal with the same voltage range. A clock signal oscillates between a high and a low state, normally with a 50% duty cycle, and is usually a square wave. A clock signal might also be gated, that is, combined with a controlling signal that enables or disables the clock signal for a certain part of a circuit. en.wikipedia.org /wiki/Clock_signal   (421 words)

Capitalization rate - Wikipedia, the free encyclopedia Capitalization rates do not, however, take into account the capital appreciation of an asset over time (an increase in value over time due to a rise in market price), nor do they traditionally factor in other cash flows, such as tax shelter and cost recovery (otherwise known as "depreciation"). One advantage of capitalization rate valuation is that it is entirely independent from an appraisal, and it is therefore often still used as a "reality check" on other value analysis. Capitalization rates are a measure of how fast an investment will pay for itself in net cash flows. en.wikipedia.org /wiki/Capitalization_rate   (421 words)

Exchange rate - Wikipedia, the free encyclopedia Exchange rates for such currencies are likely to change almost constantly as quoted on financial markets, mainly by banks, around the world. In finance, the exchange rate (also known as the foreign-exchange rate, forex rate or FX rate) between two currencies specifies how much one currency is worth in terms of the other. For example an exchange rate of 120 Japanese yen (JPY, ¥) to the United States dollar (USD, $) means that JPY 120 is worth the same as USD 1. en.wikipedia.org /wiki/Exchange_rate   (997 words)

Churn - Wikipedia, the free encyclopedia Churn rate ([1]) is the number of the average number of customers that leave a subscription service during a year. Churn (see churning) is a term used in the lingo of stockbrokers to describe the practice of convincing a customer to constantly buy and sell stocks and being misleading about the prospects of the profitability of this action (usually by not factoring in the commissions). Churn has been adopted by critics of the computer hardware industry, who accuse it of using tactics like increasing bus speed for a minor overall speed increase but which requires users to buy a new motherboard and RAM. en.wikipedia.org /wiki/Churn   (257 words)

Rate law - Wikipedia, the free encyclopedia A rate law is an equation that relates concentrations of reactants to the reaction rate. The rate law can be used in a mass balance to describe how the system changes. Zero order reactions are typically found when a material required for the reaction to proceed, such as a surface or a catalyst, is saturated by the reactants. en.wikipedia.org /wiki/Rate_law   (418 words)

Adiabatic lapse rate - Wikipedia, the free encyclopedia The Adiabatic lapse rate is the rate of temperature change that occurs in an atmosphere as a function of elevation, assuming that air behaves adiabatically. In general, a lapse rate is the rate at which an atmospheric variable (usually temperature) decreases with altitude. Charts of the environmental lapse rate are known as tephigrams. en.wikipedia.org /wiki/Dry_adiabatic_lapse_rate   (949 words)

Encyclopedia: Unemployment rate The unemployment rate measures the number of unemployed workers as a proportion of the total civilian labor force, where the latter includes both the unemployed and those with jobs (all those willing and able to work for pay). Unemployment insurance keeps an available supply of workers for the McJobs, while the employers' choice of management techniques (low wages and benefits, few chances for advancement) is made with the existence of unemployment insurance in mind. Unemployment may thus promote labor productivity and profitability. www.nationmaster.com /encyclopedia/Unemployment-rate   (949 words)
