Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
Data collection systems are an end-product of software development. Identifying and categorizing software or a software sub-system as having aspects of, or as actually being a "Data collection system" is very important. This categorization allows encyclopedic knowledge to be gathered and applied in the design and implementation of future systems.
In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...
Data collection or data gathering is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical and social sciences, humanities, [2] and business ...
The key component is allocating enough attention, as a resource, to the task at hand. Kahneman also noted that arousal influences the total attentional capacity in any given situation. [3] In addition, his model incorporates the ideas of voluntary and reflexive attention, which affect allocation policy.
A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli , and is associated with impulsivity .
It also encompasses main components of human attention including selection, divisibility, shift-ability, and sustainability. [7] Selection of attention is the ability to select to a specific task over a more salient stimulus or set of background stimuli [citation needed]. Divisibility is when attention is divided among tasks [citation needed ...
The DCSNet systems operate on a virtual private network parallel to the public Internet, with services provided at least for some time by the Sprint Peerless IP network. [3] Much of the information available on this system has come from the results of Freedom of Information Act (FOIA) requests made by the Electronic Frontier Foundation (EFF). [4]
