    Adaptive rowing is a special category of rowing sport rowing race for those with physical Disability disabilities . Under International Rowing Federation FISA rules there are three categories for adaptive rowers LTA Legs, Trunk, Arms Use of at least one leg, trunk and arms. Also for those with visually impaired visual and intellectual impairment s. Rowed with standard boats and sliding seats. TA Trunk and Arms Only use of trunk muscles. Boat has fixed seat. A Arms only Limited trunk control. Boat has fixed seat and rower is strapped at upper chest level to only allow shoulder and arm movements. At FISA events there are 4 boat events standard sport rowing Event nomenclature nomenclature is used 4 Mixed LTA 2x Mixed TA 1x Men A 1x Women A Racing is held over 1,000 m rather than the standard 2,000 m . In mixed events half the crew must be male and other half female coxswain maybe of either gender and may be able bodied . Single shells for the Arms Only category must have stabilising pontoons attached to the riggers. Adaptive events were added to the World Rowing Championships in 2002 and are due to take place at the 2008 Summer Paralympics in Beijing , China .

  1. Adaptive optimization

    Adaptive optimization is a technique in computer science that performs dynamic recompilation of portions of a computer program program based on the current execution profile. With a simple implementation, an adaptive optimizer may simply make a trade off between Just in time compilation and interpreting instructions. At another level, adaptive optimization may take advantage of local data conditions to optimize away branches and to use inline expansion to decrease context switch ing. Consider a hypothetical banking application that handles transactions one after another. These transactions may be checks, deposits, and a large number of more obscure transactions. When the program executes, the actual data may consist of clearing tens of thousands of checks without processing a single deposit and without processing a single check with a fraudulent account number. An adaptive optimizer would compile assembly code to optimize for this common case. If the system then started processing tens of thousands of deposits instead, the adaptive optimizer would recompile the assembly code to optimize the new common case. This optimization may include inlining code or moving error processing code to secondary cache. Deoptimization In some systems, notably the Java Virtual Machine , execution over a range of Java bytecode bytecode instructions can be provably reversed. This allows an adaptive optimizer to make risky assumptions about the code. In the above example, the optimizer may assume all transactions are checks and all account numbers are valid. When these assumptions prove incorrect, the adaptive optimizer can unwind to a valid state and then interpret the byte code instructions correctly.

  1. Adaptive beamformer

    Unreferenced date December 2009 An adaptive beamformer is a beamforming system which performs adaptive spatial signal processing with an array of radar antennas or phased array in order to transmit or receive signals in different directions without having to mechanically steer the array. The main distinction between an adaptive beamformer and a conventional beamforming system is the ability of the former to adjust its performance to suit differences in its environment. A particularly important feature, in military applications, is the potential for an adaptive beamformer to reduce sensitivity to certain directions of arrival so as to counteract jamming by hostile transmissions.

  1. Adaptive architecture

    Multiple issues refimprove March 2009 orphan February 2009 Adaptive architecture is a Complex adaptive system system which changes its structure, behaviour or resources according to demand . The adaptation made is usually always? to Non functional requirement non functional characteristics rather than Functional requirement functional ones. Something of a misnomer, because the thing that adapts is the working system, rather than the more abstract Systems architecture architecture which defines the adaptability that is required of that system. Adaptive software architecture Used by programmers in relation to a program. An adaptive algorithm is an algorithm which changes its behavior based on the resources available. For example in the C Standard Library , the stable partition program acquires as much memory as it can get up to what it would need at most and applies the algorithm using that available memory. Adaptive infrastructure architecture Used by infrastructure engineers in relation to the configuration of processors. The computing resources used by applications the Disk partitioning partition size, or the number of server computer servers in a cluster computing cluster , or the share of a processor, or the number of processes are configured so that they shrink or grow with demand.

  1. Adaptive filter

    An adaptive filter is a filter that self adjusts its transfer function according to an optimization algorithm driven by an error signal. Because of the complexity of the optimization algorithms, most adaptive filters are digital filter s. By way of contrast, a non adaptive filter has a static transfer function. Adaptive filters are required for some applications because some parameters of the desired processing operation for instance, the locations of reflective surfaces in a reverberant space are not known in advance. The adaptive filter uses feedback in the form of an error signal to refine its transfer function to match the changing parameters. Generally speaking, the adaptive process involves the use of a cost function , which is a criterion for optimum performance of the filter, to feed an algorithm, which determines how to modify filter transfer function to minimize the cost on the next iteration. As the power of digital signal processor s has increased, adaptive filters have become ... frequency components in the rejected range.

  1. Adaptive enzyme

    Unreferenced date December 2009 An adaptive enzyme or inducible enzyme is an enzyme that is gene expression expressed only under conditions in which it is clear of adaptive value, as opposed to a constitutive enzyme which is produced all the time. The Inducible enzyme is used for the breaking down of things in the cell. It is also a part of the Operon Model, which illustrates a way for genes to turn on and off . The Inducer causes the gene to turn on controlled by the amount of reactant which turns the gene on . Then there s the repressor protein that turns genes off. The inducer can remove this repressor, turning genes back on. The operator is a section of DNA where the repressor binds to shut off certain genes the promoter is the section of DNA where the RNA polymerase binds. Lastly, the regulatory gene is the gene for the repressor protein. An example of inducible enzyme is COX 2 which is synthesized in macrophages to produce Prostaglandin E sub 2 sub while the constitutive enzyme COX 1 another isozyme in COX family is always produced in variety of organisms in body like stomach .

  1. Adaptive recreation

    Adaptive Recreation is a concept whereby people with disabilities are given the opportunity to participate in recreational activities. Through the use of activity modifications and assistive technology , athletes or participants in sports or other recreational pursuits are able to play alongside their non disabled peers. The Boy Scouts of America , for example, has about 100,000 physically or mentally disabled members throughout the United States. ref name grolier cite web url http nbk.grolier.com cgi bin article?assetid a2003470 h title Boy Scouts format work The New Book of Knowledge publisher Grolier Online accessdate 2008 02 24 ref Activity Modifications are changes made to a game or activity that allow all players to have an equal or more equal chance of doing well. One example of an activity modification is a wheelchair basketball game, where both disabled and non disabled players use wheelchairs . The players ability to walk is no longer a factor in how well they play. Assistive Devices are any machines or equipment used to level the playing field in a mixed ability competition, or to allow someone the opportunity to participate that could not do so without its benefit. Good examples of assistive devices are http www.ncaonline.org ncpad swimming poollift.html pool lifts that lower non ambulatory swimmers into a pool, and standing frames that allow wheelchair users to stand up while playing ball.

  1. Adaptive sort

    A sorting algorithm falls into the adaptive sort family if it takes advantage of existing order in its input. It benefits from the presortedness in the input sequence or a limited amount of randomness disorder for various definitions of measures of disorder and sorts faster. Adaptive sorting is usually performed by modifying existing sorting algorithms. Motivation Comparison sort Comparison based sorting algorithms have traditionally dealt with achieving an optimal bound of Big O notation O n  logn when dealing with time complexity . Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence. In other words, the more presorted the input is, the faster it should be sorted. This is an attractive algorithm because nearly sorted sequences are common in practice. Thus, the performance of existing sort algorithms can be improved by taking into account the existing order in the input.
