Adaptive capacity is the capacity of a system to adapt if the environment where the system exists is changing. It is applied to e.g., ecology ecological systems and human social system s. As applied to ecological systems, the adaptive capacity is determined by genetic diversity of species biodiversity of particular ecosystem s heterogeneity heterogeneous ecosystem mosaics as applied to specific landscape s or biome regions.

Unreferenced date March 2009 Adaptive clothing is clothing designed for people with physical disabilities, the elderly, and the infirm who may experience difficulty dressing themselves due to an inability to manipulate closures, such as buttons and zippers, or due to a lack of a full range of motion required for self dressing . Adaptive clothing typically offers rear closure designs so that an individual can be dressed more easily by a carer. For example, rather than buttons and zippers, Velcro may be used for garment closures.

Special needs Adaptive clothing often addresses such problems as edema , urinary incontinence incontinence and inappropriate behavior issues associated with Alzheimer s disease . Different styles of adaptive clothing are best suited to an individual with disabilities based on the nature of the wearer s ailment. For example, a person who is unable to lift his arms above shoulder level would need a different clothing solution than a person suffering from incontinence.

The adaptive unconscious is a set of mental processes influencing judgment and decision making, in a way that is inaccessible to introspection introspective awareness. This conception of the unconscious mind has emerged in cognitive psychology , influenced by, but different from, other conceptions such as Sigmund Freud s. The adaptive unconscious is distinguished from conscious processing in a number of ways, including being faster, effortless, more focused on the present, and less flexible. In other theories of the mind, the unconscious is limited to low level activity, such as carrying out goals which have been decided consciously. In contrast, the adaptive unconscious is thought to be involved in high level cognition such as goal setting as well. According to Freud, the unconscious mind stored a lot of mental content which needs to be repressed. The term adaptive unconscious reflects the idea that much of what the unconscious does is beneficial to the organism that its various processes have been streamlined by evolution to quickly evaluate and respond to patterns in an organism s environment. ref name trusting cite book last Wilson first Timothy D. title Trusting the subject? the use of introspective evidence in cognitive science editor Anthony Jack, Andreas Roepstorff publisher Imprint Academic year 2003 pages 131 140 chapter Knowing When to Ask Introspection and the Adaptive ... research suggests that much of our preferences, attitudes and ideas come from the adaptive unconscious ... first Emily coauthor Matthew B.

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 .

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.

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. Adaptive Beamforming Schemes Least mean squares filter Least Mean Squares Algorithm Sample Matrix Inversion Algorithm Recursive least squares filter Recursive Least Square Algorithm Conjugate gradient method Constant Modulus Algorithm See also Beamforming is spatial signal processing which makes spatial beam focused on the target direction and spatial beam nulled interference signal. Smart Antennas is multiple antenna systems having one of three structures which are single input and multiple output SIMO , multiple input and single output MISO , and multiple input and multiple output MIMO structures.

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. To circumvent this potential loss of information, an adaptive filter could be used. The adaptive filter would take input both from the patient and from the power .... Such an adaptive technique generally allows for a filter with a smaller rejection range, which ... adaptive filter realisations, such as Least mean squares filter Least Mean Squares LMS and Recursive ... for the filter coefficients.
