Dancer Fitzgerald Sample
Dancer Fitzgerald Sample (DFS and later DFS-Dorland) was a Madison Avenue advertising agency during the 20th century. It was founded in Chicago in 1923, and was acquired and merged into the Saatchi & Saatchi network in the 1980s. History The agency was founded in 1923 by Hill Blackett and John Glen Sample, in Chicago. E. Frank Hummert joined the agency in 1927, and it was renamed Blackett-Sample-Hummert, even though Hummert was never a partner in the company. Blackett left company management, despite remaining a partner, when he was commissioned into the U.S. Navy in 1942. Hummert left the company at the end of 1943, forming Hummert Radio Productions with his wife Anne. Sample, after unsuccessful attempts to buy out the absent Blackett, announced that they would allow the firm to dissolve when their partnership agreement expired in 1944, and that he would enter a new partnership with B-S-H president Howard M. "Mix" Dancer at that time. These plans were later altered to termin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumfriesshire
Dumfriesshire or the County of Dumfries or Shire of Dumfries (''Siorrachd Dhùn Phris'' in Gaelic) is a historic county and registration county in southern Scotland. The Dumfries lieutenancy area covers a similar area to the historic county. In terms of historic counties it borders Kirkcudbrightshire to the west, Ayrshire to the north-west, Lanarkshire, Peeblesshire and Selkirkshire to the north, and Roxburghshire to the east. To the south is the coast of the Solway Firth, and the English county of Cumberland. Dumfriesshire has three traditional subdivisions, based on the three main valleys in the county: Annandale, Eskdale and Nithsdale. These had been independent provinces in medieval times but were gradually superseded as administrative areas by the area controlled by the sheriff of Dumfries, or Dumfriesshire. A Dumfriesshire County Council existed from 1890 until 1975. Since 1975, the area of the historic county has formed part of the Dumfries and Galloway council ...

Daily Fantasy Sports
Daily fantasy sports (DFS) are a subset of fantasy sport games. As with traditional fantasy sports games, players compete against others by building a team of professional athletes from a particular league or competition while remaining under a salary cap, and earn points based on the actual statistical performance of the players in real-world competitions. Daily fantasy sports are an accelerated variant of traditional fantasy sports that are conducted over short-term periods, such as a week or single day of competition, as opposed to those that are played across an entire season. Daily fantasy sports are typically structured in the form of paid competitions typically referred to as a "contest"; winners receive a share of a pre-determined pot funded by their entry fees. A portion of entry fee payments go to the provider as rake revenue. In the United States, the daily fantasy sports industry was dominated by two competing services: the New York-based FanDuel, and the Boston-bas ...

Double Fourier Sphere Method
In mathematics, the double Fourier sphere (DFS) method is a simple technique that transforms a function defined on the surface of the sphere to a function defined on a rectangular domain while preserving periodicity in both the longitude and latitude directions. Introduction First, a function f(x, y, z) on the sphere is written as f(\lambda,\theta) using spherical coordinates, i.e., : f(\lambda,\theta) = f(\cos\lambda\sin\theta,\sin\lambda\sin\theta, \cos\theta), (\lambda,\theta)\in \pi,\pitimes ,\pi The function f(\lambda, \theta) is 2\pi-periodic in \lambda, but not periodic in \theta. The periodicity in the latitude direction has been lost. To recover it, the function is "doubled up” and a related function on \pi,\pitimes \pi,\pi/math> is defined as : \tilde(\lambda,\theta) = \begin g(\lambda + \pi, \theta), & (\lambda, \theta) \in \pi, 0\times , \pi\\ h(\lambda, \theta), &(\lambda, \theta) \in , \pi\times , \pi\\ g(\lambda, -\theta), &(\lambda, \theta) \in , \pi ...

Disease-free Survival
Survival rate is a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy. The survival period is usually reckoned from date of diagnosis or start of treatment. Survival rates are based on the population as a whole and cannot be applied directly to an individual. There are various types of survival rates (discussed below). They often serve as endpoints of clinical trials and should not be confused with mortality rates, a population metric. Overall survival Patients with a certain disease (for example, colorectal cancer) can die directly from that disease or from an unrelated cause (for example, a car accident). When the precise cause of death is not specified, this is called the overall survival rate or observed survival rate. Doctors often use mean overall surviva ...

Digital Frequency Synthesizer
A digital clock manager (DCM) is an electronic component available on some field-programmable gate arrays (FPGAs) (notably ones produced by Xilinx). A digital clock manager is useful for manipulating clock signals inside the FPGA, and to avoid clock skew which would introduce errors in the circuit. Uses Digital clock managers have the following applications: xilinx.com * Multiplying or dividing an incoming clock (which can come from outside the FPGA or from a Digital Frequency Synthesizer FS. * Making sure the clock has a steady duty cycle. * Adding a phase shift with the additional use of a delay-locked loop. * Eliminating clock skew within an FPGA design. See also * Phase-locked loop A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input signal. There are several different types; the simplest is an electronic circuit consisting of a ... References Gate arrays Electronic os ...

Design For X
Design for Excellence or Design For Excellence (DfX or DFX), are terms and expansions used interchangeably in the existing literature, where the ''X'' in ''design for X'' is a variable which can have one of many possible values. In many fields (e.g., very-large-scale integration (VLSI) and nanoelectronics) ''X'' may represent several traits or features including: manufacturability, power, variability, cost, yield, or reliability.Saraju Mohanty, Chapter 3 Nanoelectronics Issues in Design for excellence,Nanoelectronic Mixed-Signal System Design, and 0071825711, 1st Edition, McGraw-Hill, 2015. This gives rise to the terms design for manufacturability (DfM, DFM), design for inspection (DFI), design for variability (DfV), design for cost (DfC). Similarly, other disciplines may associate other traits, attributes, or objectives for ''X''. Under the label ''design for X'', a wide set of specific design guidelines are summarized. Each design guideline addresses a given issue that is cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoherence-free Subspaces
A decoherence-free subspace (DFS) is a subspace of a quantum system's Hilbert space that is invariant to non-unitary dynamics. Alternatively stated, they are a small section of the system Hilbert space where the system is decoupled from the environment and thus its evolution is completely unitary. DFSs can also be characterized as a special class of quantum error correcting codes. In this representation they are ''passive'' error-preventing codes since these subspaces are encoded with information that (possibly) won't require any ''active'' stabilization methods. These subspaces prevent destructive environmental interactions by isolating quantum information. As such, they are an important subject in quantum computing, where (coherent) control of quantum systems is the desired goal. Decoherence creates problems in this regard by causing loss of coherence between the quantum states of a system and therefore the decay of their interference terms, thus leading to loss of information ...

Distributed File System (Microsoft)
Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency (via the namespace component) and Redundancy (via the file replication component). Together, these components enable data availability in the case of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, the "DFS root". Microsoft's DFS is referred to interchangeably as 'DFS' and 'Dfs' by Microsoft and is unrelated to the DCE Distributed File System, which held the 'DFS' trademark but was discontinued in 2005. It is also called "MS-DFS" or "MSDFS" in some contexts, e.g. in the Samba user space project. Overview There is no requirement to use the two components of DFS together; it is perfectly possible to use the logical namespace component without using D ...
