Matching unit

Reaction can be initiated by several means, aH of which depend on deHvery of heat at a relatively high temperature to a starting cone. Cartridge-actuated and electric match units are usuaHy used. The former is in the majority. A water-activated unit has been described (12). The heat generated by the starting device initiates reaction in a cone, which is a smaH amount of candle that is higher in fuel content, eg, 30 wt % iron. Compared to... 

A model of some multidimensional observations, possibly a vector consisting of features (variables), is associated with each unit. The map attempts to represent all available observations with optimal accuracy using a restricted set of models. At the same time the models become ordered on the grid so that similar models are close to each other and dissimilar models far from each other. Fitting of the model vectors is usually carried out by a sequential regression process, where t = 1, 2,... is the step index. For each sample x(t), the winner index c (best matching unit—BMU) is first identified by the condition... 

These results are similar to daily-averaged values reported by Barrie (18) for sites in eastern Canada (1978-1981). His mass scavenging ratios, multiplied by 890 (the ratio between the density of water and that of air at the 838-m altitude of Allegheny Mountain in order to match units), give the following averages for 4 remote locations ... 

Step 1. Selecting the winner prototype. Given an input data vector, the competitive units compete each other to select the winner neuron comparing their prototypes with the input. This winner unit, also called Best Matching Unit (BMU) is selected in MSCL as the one that minimizes the product of a user-defined Magnitude Function and the distance of the unit prototypes to the input data vector. This differs from other usual competitive algorithms where BMU is determined only by distance. MSCL is implemented by a two-step competition global and local, as it is explained in next section. 

M unit weights are initialized with data inputs randomly selected from the dataset, and their initial value of its magnitude is equal to the magnitude function at these samples. We also initialize to ones the value of a counter rii of the number of times that each unit has been the best matching unit. 

A function calculated depending on the unit weights and/or the values of data samples belonging to its Voronoi region. An example of this function is the used for Homogeneous Color Quantization. In that case mf t) is the value of the mean quantization error of the best matching unit of x(t). 

The matching unit permits the maximum of the RF energy from the generator to be transferred to the product. Such an optimum power transfer (reflected power is zero) is only possible when the input impedance of the applicator is equal to the output impedance of the generator. To match the... 

The torch is where the main ionization process takes place at temperatures of 6000-10,000 K. This is induced by an RF power unit and a plasma RF matching unit. 

Epitaxy is defined as the growth of one crystalline phase (the guest crystal, here the polymer) on the surface of a crystal of another phase (the host crystal, here the substrate) in one or more strictly defined crystallographic orientations. The interactions imply a structure analogy between the two species in their contact planes, either in two, or sometimes only one direction. The details of the molecular interactions may be difficult to reach, and, as a consequence, the epitaxy is often defined in terms of a geometrical concordance of matching unit-cell dimensions the disregistries should remain < 10%. 

In the on-line application, the feed data is 8-hour mean values achieved from the history database at the plant. The interface shows changes in bed stability by a five-days path (5x3 observations) of the best-matching unit (BMU) on the map. The BMU is the unit representing the prototype vector with shortest distance to the input vector. Also, the application outputs a plot of the quantization error (Euclidean distance between BMU and input vector) for the same period, which can be used as an indicator of model reliability. 

Death Although umbilical cord blood transplantation has become standard treatment in children with hematological malignancies, in adults it is limited by a minimum cell dose. A new option is administration of two partially matched units of cord blood, but this increases the risk of complications. Death has occurred after double cord blood transplantation and multiple transfusions in a woman in whom an earlier pregnancy might have predisposed to sensitization [IIS ].
