Immune-mediated disease

Immune-mediated diseases are conditions which result from abnormal activity of the body's immune system. The immune system may over-react (for example, immune-mediated contact dermatitis) or start attacking the body (for example, autoimmune hemolytic anemia). Autoimmune diseases are a subset of immune-mediated diseases.

System.map

In Linux, the System.map file is a symbol table used by the kernel.

OHB-System

OHB-System employs approximately 300 persons.

SYSTEM.INI

SYSTEM.INI was a basic INI file used in early versions of Microsoft Windows to load device drivers and the default Windows shell (Program Manager or Windows Explorer). Many of these settings were honored in Windows 9x, although the files had begun to be phased out in favor of the Windows registry. Windows XP still acknowledges some entries in the SYSTEM.INI file, to provide backwards compatibility with older 16-bit applications. However, when a fresh install of XP is performed, the SYSTEM.INI file created is initially blank.

System

The concept of an "integrated whole" can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the set and elements not a part of the relational regime.

Q-system

The Q-factor can then be calculated as:

FAC-System

FAC-System is a mechanical prototyping system, invented by Swedish artist Mark Sylwan in 1952. It uses mainly metallic parts, and extensively uses 4mm steel rod.

L-system

An L-system or Lindenmayer system is a parallel rewriting system, namely a variant of a formal grammar (a set of rules and symbols), most famously used to model the growth processes of plant development, but also able to model the morphology of a variety of organisms. L-systems can also be used to generate self-similar fractals such as iterated function systems. L-systems were introduced and developed in 1968 by the Hungarian theoretical biologist and botanist from the University of Utrecht, Aristid Lindenmayer (1925–1989).

System-specific impulse

The term System-specific Impulse, I_ssp is mostly used to describe the performance of jet propulsion systems. A reference number is introduced, which defines the total impulse, I_tot, delivered by the system, divided by the system mass, m_PS:

Graves (System)

GRAVES (Grand Réseau Adapté à la Veille Spatiale) is a French radar-based space surveillance system, akin to the American NAVSPASUR. Using radar measurements, the French Air Force is able to spot satellites orbiting the Earth and determine their orbit. The GRAVES system took 15 years to develop, and became operational in November, 2005.
