Classification, generally purpose

Design B motors are the most popular in industry. As the classification general purpose imphes, the NEMA design B motors can be used to drive most loads such as pumps, fans, and conveyors. 

According to the Technical Manual published in 1966 and listed here as Ref 51a, the new classification of US bombs is as follows 1) Semi-Armor-Piercing (SAP) 2) Fragmentation (Frag) 3) General Purpose (GP) 4) Incendiary (Inc or I)... 

The serious development of synthetic rubbers commenced in the late 1930s and early 194(ls. accelerated by a cutoff of supplies of natural rubber because of political turmoil and war. Synlhetic rubbers fall into two major classifications (1) general-purpose rubbers, the major volume of which is nevertheless used for tire production and (2) specialty rubbers that essentially find little use in (ires, hut that are important for a number of other categories. Synthetic rubbers have not replaced natural rubber for numerous uses. For large, heavy-duty truck and bus tires, natural rubber tends to mn considerably cooler and wears better than a blend of natural and synthetic rubbers. On the other hand, a tire (read made of a blend of styrene-butadiene (SBR) and butadiene rubber (polybutadiene) wears longer than natural rubber in conventional automobile, usage, where lower temperatures can be maintained. 

Bombs, Demolition. Former classification for bombs that exploded after short penetration, accomplishing damage and destruction by both blast and underground explosion. A demolition bomb of WWII had a charge approx equal to 50% of the bomb s total wt. The present classification of such a bomb is GP(general purpose). See also under BOMBS Ref Glossary of Ord( 1959), 42... 

For the purpose of drug treatment, the epilepsies are classified according to the seizure type. The classification generally used is based on that proposed by the Commission on Classification and Terminology of the International League against Epilepsy. The main groups are ... 

Frenkel [5] classifies raw water supplies into several types with different characteristics (Table 12.1). Other authors propose similar classifications and often add hardness to the list of characteristics. Arden and Forrest [6] take a modular proach to treatment. Silted river water, for example, considered suitable only for irrigation, is improved by sedimentation to a quality comparable to that of most other surface waters. The clarified water then becomes suitable for crude industrial applications. Coagulation and filtration then virtually eliminate suspended solids and make the water suitable for general purposes. These include plant utility use without necessarily qualifying the water for process application. Beyond this point, the intended application determines the extent of treatment required. 

Instrumentation Purging. A hazard classification can be reduced by continuous addition of air or inert gas to a general-purpose enclosure. For example, totally enclosed control panels which contain electronic devices that are not rated for Division I can be used in that service if purged according to ISA S12.4. A purged control panel cannot be opened for adjustments or maintenance if explosive vapors are present or if the components are powered. Electrical power can not be reinstated imtil the panel has been closed and purged of all explosive vapors. 

Accordingly dense stereo and optical flow methods are powerful computer vision algorithms for the general purpose of spatial and temporal scene reconstruction. However, they do not provide a classification of the visible objects in the scene. For applications in which it is crucial to depict or emphasize, the motion or distance of a specific object a different approach has to be taken. 

The polarity of the stationary-phase liquid can be characterized by a number of parameters. For this purpose, Rohrschneider in 1966 and subsequently McRey-nolds [10] in 1970 proposed a number of test components, representing specific interactions between groups of analytes and the stationary phases. The Kovats retention indices (see section 2.4) of the model compounds benzene, 1-butanol, 2-pentanone, nitropropane, and pyridine on different stationary phases are used to determine the McReynolds constants on these stationary phases. Based on the McReynolds constants, the GC column manufacturer Chrompack introduced the CP index in order to characterize the polarity of stationary phases. The CP index has a value of zero for the highly nonpolar phase squalane and a value of 100 for the very polar phase OV 275. The CP index facilitates the comparison of stationary phases from different manufacturers. A number of general-purpose stationary phases are given in Table 2. Other classification systems for GC sta tionary phases have recently been reviewed by Abraham et al. [llj. 

Since plastic materials are seldom supplied without the addition of certain additives and fillers, a classification system must be used to avoid confusion. For example, the specification for acetal materials covers three main types of acetal resins homopolymer, copolymer, and terpolyerm. The resin types are subdivided into classes according to the grade descriptions. The group 1, class 1 represents general-purpose homopolymer acetal resin, and group 2, class 3 represents impact modified copolymer acetal resin. Table 1-1 lists the detailed requirements for acetal materials. 

The proposed approach reveals that the automatic design of Artificial Neural Networks by means of multi-objective optimization is a viable solution in the context of complex classification problems. This is especially true when any prior information about the problem at hand is scarce, or not available at all. Furthermore, such an automatic design has a high degree of general purposeness, as it can be easily extended to different classification tasks. 

The use of light olefins, diolefins, and aromatic-based monomers for producing commercial polymers is dealt with in the last two chapters. Chapter 11 reviews the chemistry involved in the synthesis of polymers, their classification, and their general properties. This book does not discuss the kinetics of polymer reactions. More specialized polymer chemistry texts may be consulted for this purpose. 

The similarity in approach to LDA (Section 33.2.2) and PLS (Section 33.2.8) should be pointed out. Neural classification networks are related to neural regression networks in the same way that PLS can be applied both for regression and classification and that LDA can be described as a regression application. This can be generalized all regression methods can be applied in pattern recognition. One must expect, for instance, that methods such as ACE and MARS (see Chapter 11) will be used for this purpose in chemometrics.
