Single-member District
A single-member district is an electoral district represented by a single officeholder. It contrasts with a multi-member district, which is represented by multiple officeholders. Single-member districts are also sometimes called single-winner voting, winner-takes-all, or single-member constituencies. A number of electoral systems use single-member districts, including plurality voting (first-past-the-post), two-round systems, instant-runoff voting (IRV), approval voting, range voting, Borda count, and Condorcet methods (such as the Minimax Condorcet, Schulze method, and Ranked Pairs). Of these, plurality and runoff voting are the most common. In some countries, such as Australia and India, members of the lower house of parliament are elected from single-member districts; and members of the upper house are elected from multi-member districts. In some other countries like Singapore, members of parliament can be elected from both single-member districts as well as multi-member ...

SMD LED
The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs).SMD-LED-Module-Definitiowhat is a SMD LED Modulehttps://www.optonicaled.at] Non-SMD types of LED lighting also exist, such COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may have three individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected, by varying the brightness of the individual LEDs. LED brightness may be increased by using a higher driving current Currents, Current or The Current may refer to: Science and technology * Current (fluid), the flow of a liquid or a gas ** Air current, a flow of air ** Ocean current, a current in the ocean *** Rip current, a kind of water current ** Current (stre ..., at the cost of reducing the device's lifespan.

Surface-mount Technology
Surface-mount technology (SMT), originally called planar mounting, is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality. It also allows for more components to fit on a given area of substrate. Both technologies can be used on the same board, with the through-hole technology often used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors. An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Module Device
Storage Module Drive (SMD) is a family of storage devices ( hard disk drives) that were first shipped by Control Data Corporation in December 1973 as the CDC 9760 40 MB (unformatted) storage module disk drive.Control Data Corporation Newsletter, Summer 1977 Edition, p. 6 The CDC 9762 80 MB variant was announced in June 1974 and the CDC 9764 150 MB and the CDC 9766 300 MB variants were announced in 1975 (all capacities unformatted). A non-removable media variant family of 12, 24 and 48 MB capacity, the MMD, was then announced in 1976. This family's interface, SMD, derived from the earlier Digital RP0x interface, was documented as ANSI Standard X3.91M - 1982, Storage Module Interfaces with Extensions for Enhanced Storage Module Interfaces. The SMD interface is based upon a definition of two flat interface cables ("A" control and "B" data) which run from the disk drive to a controller and then to a computer. This interface allows data to be transferred at 9.6 Mbit/s. The SMD inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereotypic Movement Disorder
Stereotypic movement disorder (SMD) is a motor disorder with onset in childhood involving restrictive and/or repetitive, nonfunctional motor behavior (e.g., hand waving or head banging), that markedly interferes with normal activities or results in bodily injury. To be classified as SMD, the behavior in question must not be due to the direct effects of a substance, autism, or another medical condition. The cause of this disorder is not known. Signs and symptoms Common repetitive movements of SMD include head banging, arm waving, hand shaking, rocking and rhythmic movements, self-biting, self-hitting, and skin-picking; other stereotypies are thumb-sucking, dermatophagia, nail biting, trichotillomania, bruxism and abnormal running or skipping. Cause The cause of stereotypic movement disorder is unknown. Diagnosis Stereotyped movements are common in infants and young children; if the child is not distressed by movements and daily activities are not impaired, diagnosis is not warr ...

Sauter Mean Diameter
In fluid dynamics, Sauter mean diameter (SMD, ''d''32 or ''D'' , 2 is an average of particle size. It was originally developed by German scientist Josef Sauter in the late 1920s. It is defined as the diameter of a sphere that has the same volume/surface area ratio as a particle of interest. Several methods have been devised to obtain a good estimate of the SMD. SMD is typically defined in terms of the surface diameter, ''d''''s'': :d_s = \sqrt and volume diameter, ''d''''v'': :d_v = \left(\frac\right)^, where ''A''''p'' and ''V''''p'' are the surface area and volume of the particle, respectively. If ''d''''s'' and ''d''''v'' are measured directly by other means without knowledge of ''A''''p'' or ''V''''p'', Sauter diameter for a given particle is :SD = D ,2= d_ = \frac. If the actual surface area, ''A''''p'' and volume, ''V''''p'' of the particle are known the equation simplifies further: :\frac = \frac = \frac = \frac :d_ = 6\frac. This is usually taken as the mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Effect Size
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size value. Examples of effect sizes include the correlation between two variables, the regression coefficient in a regression, the mean difference, or the risk of a particular event (such as a heart attack) happening. Effect sizes complement statistical hypothesis testing, and play an important role in power analyses, sample size planning, and in meta-analyses. The cluster of data-analysis methods concerning effect sizes is referred to as estimation statistics. Effect size is an essential component when evaluating the strength of a statistical claim, and it is the first item (magnitude) in the MAGI ...

Doctor Of Musical Arts
The Doctor of Musical Arts (DMA) is a doctoral academic degree in music. The DMA combines advanced studies in an applied area of specialization (usually music performance, music composition, or conducting) with graduate-level academic study in subjects such as music history, music theory, or Music education. The DMA degree usually takes about three to four years of full-time study to complete (in addition to the master's and bachelor's degrees), preparing students to be professional performers, conductors, and composers. As a terminal degree, the DMA qualifies its recipient to work in university, college, and conservatory teaching/research positions. Students seeking doctoral training in musicology or music theory typically enter a DME or Ph.D. program, rather than a DMA program. Terminology The degree is also abbreviated as DMusA or AMusD. For the related degree Doctor of Music, the abbreviation is DM or DMus. For the related degree Doctor of Arts, the abbreviation DA is us ...
