Boost (C++ libraries)

Boost is a set of libraries for the C++ programming language that provide support for tasks and structures such as linear algebra, pseudorandom number generation, multithreading, image processing, regular expressions, and unit testing. It contains over eighty individual libraries.

Most of the Boost libraries are licensed under the Boost Software License, designed to allow Boost to be used with both free and proprietary software projects. Many of Boost's founders are on the C++ standards committee, and several Boost libraries have been accepted for incorporation into both the C++ Technical Report 1 and the C++11 standard.

Design

The libraries are aimed at a wide range of C++ users and application domains. They range from general-purpose libraries like the smart pointer library, to operating system abstractions like Boost FileSystem, to libraries primarily aimed at other library developers and advanced C++ users, like the template metaprogramming (MPL) and domain-specific language (DSL) creation (Proto).

Turbocharger

A turbocharger, or turbo (colloquialism), from Greek "τύρβη" ("wake"), (also from Latin "turbo" ("spinning top"),) is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine's output results because the turbine can force more air, and proportionately more fuel, into the combustion chamber than atmospheric pressure alone.

Turbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term "supercharger" is usually applied only to mechanically driven forced induction devices. The key difference between a turbocharger and a conventional supercharger is that a supercharger is mechanically driven by the engine, often through a belt connected to the crankshaft, whereas a turbocharger is powered by a turbine driven by the engine's exhaust gas. Compared to a mechanically driven supercharger, turbochargers tend to be more efficient, but less responsive. Twincharger refers to an engine with both a supercharger and a turbocharger.

GlaxoSmithKline

GlaxoSmithKline plc (GSK) is a British pharmaceutical company headquartered in Brentford, London. Established in 2000 by a merger of Glaxo Wellcome and SmithKline Beecham, GSK was the world's sixth largest pharmaceutical company as of 2015, after Pfizer, Novartis, Merck, Hoffmann-La Roche and Sanofi.Andrew Witty has been the chief executive officer since 2008.

The company has a primary listing on the London Stock Exchange and is a constituent of the FTSE 100 Index. As of December 2015 it had a market capitalisation of £65 billion, the fifth largest on the London Stock Exchange. It has a secondary listing on the New York Stock Exchange.

GSK's drugs and vaccines earned £21.3 billion in 2013; its top-selling products that year were Advair, Avodart, Flovent, Augmentin, Lovaza and Lamictal. GSK's consumer products, which earned £5.2 billion in 2013, include Sensodyne and Aquafresh toothpaste, the malted-milk drink Horlicks, Abreva for cold sores, Breathe Right nasal strips, Nicoderm and Nicorette nicotine replacements, and Night Nurse, a cold remedy. The company developed the first malaria vaccine, RTS,S, which it said in 2014 it would make available for five percent above cost. Legacy products developed at GSK include several listed in the World Health Organization Model List of Essential Medicines, such as amoxicillin, mercaptopurine, pyrimethamine and zidovudine.

USGS DEM

The USGS DEM standard is a geospatial file format developed by the United States Geological Survey for storing a raster-based digital elevation model. It is an open standard, and is used throughout the world. It has been superseded by the USGS's own SDTS format but the format remains popular due to large numbers of legacy files, self-containment, relatively simple field structure and broad, mature software support.

DEM Level

A USGS DEM can be classified into one of four levels of quality. This is due to the multiple methods of data collection, and certainty in the data.

Format Structure

The USGS DEM format is a self-contained (single file) set of ASCII-encoded (text) 1024-byte (1024 ASCII chars) blocks that fall into three record categories called A, B, and C. There is no cross-platform ambiguity since line ending control codes are not used, and all data including numbers is represented in readable text form. There is no known binary analogue of the format, although it is common practice to compress the files with gzip.

Demai (Talmud)

Demai (Hebrew: דמאי‎) is the third tractate of Seder Zeraim ("Order of Seeds") of the Mishnah and of the Talmud. There is some debate as to the literal meaning and origin of the word. It is concerned mainly with laws related to produce where it is suspected that ma'aser rishon (the first tithe for the Levi), terumat ma'aser and ma'aser sheini (the second tithe) or ma'aser ani (the tithe for the poor), depending on the year of the Shemittah cycle, have not been properly separated in accordance with Num. 18:24-28. It consists of seven chapters and has a Gemara from only the Jerusalem Talmud.
