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 ...
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 ...
There is much documentation of the history and necessity of the Declaration of Helsinki. The first code of conduct for research including medical ethics was the Nuremberg Code. This document had large ties to Nazi war crimes, as it was introduced in 1997, so it didn't make much of a difference in terms of regulating practice.
An allocation vector x whose i-th coordinate is the allocation for flow i, i.e. the rate at which the user i is allowed to emit data. An allocation of rate x is “max-min fair” if and only if an increase of any rate within the domain of feasible allocations must be at the cost of a decrease of some already smaller rate.
Health insurance stocks jumped after Donald Trump won the presidential election on expectations for deregulation in the industry, but shares tumbled after the killing of UnitedHealthcare CEO Brian ...
DCA was created in 1979 by Mark Hill of the United Kingdom's Institute for Terrestrial Ecology (now merged into Centre for Ecology and Hydrology) and implemented in FORTRAN code package called DECORANA (Detrended Correspondence Analysis), a correspondence analysis method. DCA is sometimes erroneously referred to as DECORANA; however, DCA is the ...
In ethics, dual loyalty is loyalty to two separate interests that potentially entails a conflict of interest.. A frequently cited example of the term "dual loyalty" is used in connection with physicians who must balance, on the one hand, the physician's loyalty to a patient (and/or the regulations that govern the physician-patient relationship), and on the other hand, the institution or ...
HCPCS was established in 1978 to provide a standardized coding system for describing the specific items and services provided in the delivery of health care. Such coding is necessary for Medicare , Medicaid , and other health insurance programs to ensure that insurance claims are processed in an orderly and consistent manner.
