Peephole optimizationPeephole optimization is an optimization technique performed on a small set of compiler-generated instructions; the small set is known as the peephole or window. Peephole optimization involves changing the small set of instructions to an equivalent set that has better performance.
Stiff equationIn mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable, unless the step size is taken to be extremely small. It has proven difficult to formulate a precise definition of stiffness, but the main idea is that the equation includes some terms that can lead to rapid variation in the solution.
Optimizing compilerIn computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program. Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers). Compiler optimization is generally implemented using a sequence of optimizing transformations, algorithms which take a program and transform it to produce a semantically equivalent output program that uses fewer resources or executes faster.
Statistical parameterIn statistics, as opposed to its general use in mathematics, a parameter is any measured quantity of a statistical population that summarises or describes an aspect of the population, such as a mean or a standard deviation. If a population exactly follows a known and defined distribution, for example the normal distribution, then a small set of parameters can be measured which completely describes the population, and can be considered to define a probability distribution for the purposes of extracting samples from this population.
Marco EvaristtiMarco Evaristti (born 1963) is a Chilean artist who has lived in Denmark since the 1980s. While a trained and practicing architect, he is best known for hosting a dinner party where the main course was agnolotti pasta that was topped with a meatball made with his own fat, removed earlier in the year in a liposuction operation. Though raised a Catholic, in his teenage years Evaristti found out he was born to a Jewish mother, which some account for the philosophical and religious themes in his work.
Thermal efficiencyIn thermodynamics, the thermal efficiency () is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the coefficient of performance) is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work).
Observational errorObservational error (or measurement error) is the difference between a measured value of a quantity and its true value. In statistics, an error is not necessarily a "mistake". Variability is an inherent part of the results of measurements and of the measurement process. Measurement errors can be divided into two components: random and systematic. Random errors are errors in measurement that lead to measurable values being inconsistent when repeated measurements of a constant attribute or quantity are taken.
Energy conversion efficiencyEnergy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle.
Federico CastellónFederico Castellón ( – ) was a Spanish American painter, sculptor, printmaker, and illustrator of children's books. Castellón was born on Alhabia, Almeria, Spain, studied in Madrid and Paris and settled in Brooklyn, New York. Federico Cristencia de Castellón y Martínez, better known as Federico Castellón, was a surrealist printmaker, illustrator, painter, and sculptor. He was born in Almeria, Spain in 1914. With his family, he immigrated in 1921 to the United States. They resided in Brooklyn, New York.

José María CanoJosé Cano Andrés (born 21 February 1959) is a Spanish visual artist, musician, composer, and record producer. From 1982 to 1998, he was a member and principal composer of the Spanish pop-rock band Mecano. Since 1998, he works primarily in the visual arts. José Maria Cano was born in Madrid, and gave his first concerts as a university student there. There he met Ana Torroja, who would become the lead singer in their pop band Mecano. Their first album, also called Mecano (1981) and produced with the financial backing of his father, included the hit "Hoy No Me Puedo Levantar".
André MeyerAndré Benoît Mathieu Meyer (September 3, 1898 – September 9, 1979) was a French-American investment banker. Meyer was born to a low-income Jewish family in Paris. As a boy, he began following the workings of the stock market and out of necessity left school at age sixteen to work as a messenger at the Paris Bourse. Ambitious, he used his time to study the intricacies of stock trading and because of personnel shortages created by so many young French men serving in the military in World War I, he was able to get a job with Baur & Fils, a small Paris bank.
