The original Exchange Rate Mechanism was formed in 1979 but superseded in 1999 when the euro was adopted as official currency of 11 EU member states. A new exchange rate mechanism (ERM II) based on the euro is used to regulate the currencies of participating states that have not adopted the euro
  • evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, the evolution strategy, evolutionary programming, and artificial life.
  • evolutionary programming — (EP) A stochastic optimisation strategy originally conceived by Lawrence J. Fogel in 1960. An initially random population of individuals (trial solutions) is created. Mutations are then applied to each individual to create new individuals. Mutations vary in the severity of their effect on the behaviour of the individual. The new individuals are then compared in a "tournament" to select which should survive to form the new population. EP is similar to a genetic algorithm, but models only the behavioural linkage between parents and their offspring, rather than seeking to emulate specific genetic operators from nature such as the encoding of behaviour in a genome and recombination by genetic crossover. EP is also similar to an evolution strategy (ES) although the two approaches developed independently. In EP, selection is by comparison with a randomly chosen set of other individuals whereas ES typically uses deterministic selection in which the worst individuals are purged from the population.
  • family income supplement — a benefit formerly paid to low-income families
  • federal trade commission — FTC.
  • flexible assembly system — A flexible assembly system is a set of machines or robots that can assemble many different kinds of products.
  • floating decimal (point) — a decimal (point) whose position is not fixed
  • free and accepted masons — a member of a widely distributed secret order (Free and Accepted Masons) having for its object mutual assistance and the promotion of brotherly love among its members.

  • frequent-flyer programme — a plan or system under which frequent flyers earn rewards for being regular customers
  • geographical determinism — the theory that human activity is determined by geographical conditions

  • guaranteed annual income — Also called guaranteed income. compensation provided by the government to any family or individual whose annual income falls below a specified level.
  • hairdressing appointment — an appointment to have your hair cut, styled, coloured, etc, at a hairdresser
  • have had a drop too much — to be drunk
  • have the drop on someone — to have the advantage over someone
  • hierarchical data format — (file format, data)   (HDF) A library and multi-object file format for the transfer of graphical and numerical data between computeres. The freely available HDF distribution consists of the library, command line utilities, test suite source, Java interface, and the Java-based HDF Viewer (JHV). HDF supports several different data models, including multidimensional arrays, raster images, and tables. Each defines a specific aggregate data type and provides an API for reading, writing, and organising the data and metadata. New data models can be added by the HDF developers or users. HDF is self-describing, allowing an application to interpret the structure and contents of a file without any outside information. One HDF file can hold a mixture of related objects which can be accessed as a group or as individual objects. Users can create their own grouping structures called "vgroups". HDF files can be shared across most common platforms, including many workstations and high performance computers. An HDF file created on one computer can be read on a different system without modification.
  • hierarchical file system — (file system)   A file system in which the files are organised into a hierarchy. The nodes of the hierarchy are called directories while the leaves are the files themselves. See also root directory. Compare flat file system.
  • high performance fortran — (language)   (HPF) A data parallel language extension to Fortran 90 which provides a portable programming interface for a wide variety of target platforms. The original HPF language specification was produced by the High Performance Fortran Forum, a broad consortium of industry and academia, which met regularly throughout 1992 and early 1993. HPF compilers are now available on most commonly-used computing systems, and users are beginning to gain first hand experience with this language. The Forum has continued to meet in order to address advanced topics.
  • high performance routing — (networking)   (HPR) Routing designed to work in conjunction with APPN Intermediate Session Routing (ISR) network nodes. HPR nodes perform many of the same functions as ISR nodes. For example, HPR nodes use the same method of calculating routes based on the Topology Routing Service database and class of service tables. HPR nodes also supports such APPN features as connection networks and support for parallel transmission groups (TGs). In the HPR architecture, both partner nodes must support HPR for RTP connections to take place between the nodes. If one node supports HPR and the partner node does not, then the link will support ISR functionality only.
  • homolographic projection — an equal-area projection in which the proportion between regions of unequal area is correctly shown.
  • human potential movement — a movement in psychology that includes group therapy, encounter therapy, primal therapy, etc., is based mainly on Freudian and Gestalt psychology, and is aimed at self-realization
  • human-computer interface — (software, hardware)   (HCI) Any software or hardware that allows a user to interact with a computer. Examples are WIMP, command-line interpreter, or virtual reality. See also Human-Computer Interaction.
  • hyperbetalipoproteinemia — An abnormally high level of betalipoprotein in the blood.
  • implicit differentiation — a method of finding the derivative of an implicit function by taking the derivative of each term with respect to the independent variable while keeping the derivative of the dependent variable with respect to the independent variable in symbolic form and then solving for that derivative.
  • incomplete metamorphosis — insect development, as in the grasshopper and cricket, in which the change is gradual and characterized by the absence of a pupal stage. Compare complete metamorphosis.
  • information architecture — the design and organization of an online resource, usually with regard to usability.
  • information superhighway — internet
  • intermediate-level waste — radioactive waste material, such as reactor and processing-plant components, that is solidified before being mixed with concrete and stored in steel drums in deep mines or beneath the seabed in concrete chambers
