Major Components of the System

It has been shown in several biological assembly systems that, due to the fact that tertiary structure determines quaternary structure, a major component of the system can be assembled on its own to form structures similar to the intact organelle (Caspar and Klug, 1962). Ex-... 

The major components of the system include a krypton gas injector assembly, a radiation detector assembly, detector electronics and a data processor. The heart of the system is the radiotracer detector assembly which uses semiconductor charged particle detectors to measure the relative concn of tracer gas in the ullage. Krypton-85 is considered the safest radioisotope for such use since there is virtually no bodily retention of this gas... 

The description of the lyophilization equipment provides a general overview of the lyophilizer, the installation site, operation, and functions. The description also identifies the major components of the system. From the listing of the major... 

Above the expansion zone is a section housing a filter (G/9). In a standard fluid bed agglomerator fluidization is interrupted to shake the fine particles from the filter (10). The final major component of the system is a fan (H/11) which draws air through the apparatus. Clean, spent air exhausts to the atmosphere (12). 

The aim of this chapter is to present examples of incorporating complexity into population dynamic models of animal systems, which could be used for risk assessment purposes, and to give an idea of what is currently being done and what might be possible. The model system used is ALMaSS (Topping et al. 2003). ALMaSS is short for Animal, Landscape, and Man Simulation System, which indicates the 3 major components of the system. 

In every engineering discipHne, measurement facilitates the use of structured procedures and decisionmaking processes. In rehabihtation engineering, the presence of a human, the only or major component of the system of interest, has presented a number of unique challenges with regard to measurement. This is especially true with regard to the routine processes of rehabilitation that either do or could incorporate and rely on measurements. This, in part, is due to the complexity of the human system s architecture, the variety of ways in which it can be adversely affected by disease or injury, and the versatility in the way it can be used to accompHsh various tasks of interest to an individual. 

Fractal geometry defines how objects occupy space. There are a variety of different methods that are employed for estimating D. For example, different approaches are used depending on whether biotic or abiotic components are measured or according to the size of the major components of the system. For example, an embedding. 

The abrasive nature of slurries is a major consideration in design and selection of equipment for the slurry system. Proper selection and layout of major components of the system — pumps, pipe, valves and fittings, and instrumentation — are important for the proper functioning of the system. 

Volume reduction of concentrated evaporator bottoms, which may include boric acid wastes, laundry wastes, chemical wastes, and other floor drain wastes, is accomplished in the radwaste volume reduction system. The major components of the system are the crystallizer chamber and recirculation system, condenser, and vacuum pump system. The crystallizer chamber consists of a conical tank and an inner circular baffle to separate solid crystals from a clear recycle stream. Combustible wastes such as clothing, filter cartridges, and wood are volume-reduced in the radwaste incinerator. Solidification of volume-reduced wastes and other low-level radioactive wastes, such as spent resins and contaminated tools, is performed in the cement solidification system. The major components of the cement solidification system include the high shear radwaste mixer, waste dispensing system, flush water recycle steam, cement storage and feed system, and the container handling system. 

A block diagram of the laser-addressed LCLV is shown in Fig. 7.39. Major components of the system... 

The schematic shows the major components of the system. Some of the principal components are the cryotank, a flapper valve, fluid lines, valves, relief valves, burst disks, electric switches, and bayonet couplers. 

For the evaluation of the effects of links across boundaries the method suggested by ICI and the defense standard is to use the typical hazard study 3 guide words (more of, less of, none of, other than, sooner/later than, corruption of, what else, reverse of) applied to data transfers between major components of the system. 

The list should be much more extensive for the system and then a similar list can be generated for the system components. Each component should have a requirement and a specification so that it is possible to verify that the component meets the requirement and specification. As an illustration, some of the more obvious requirements and specifications for an LVAD will be discussed. For this example, the major components of the system could consist of an external battery pack/transcutaneous energy source with external energy transmission coil, internal energy transmission coil, implanted pump, implanted battery pack and controller, and interconnecting cabling. These components must be broken down into subcomponents such as wires and connectors, cannula, and other individual components. 

There is ample literatime by the American Society of Mechanical Engineers (ASME), the American Society for Testing and Materials, the NBS, and others that deals with calibration methods, specifications for construction and usage of measuring instruments and temperature comparators, and processing of calibration data. It is advisable in each case to have the major components of the system (primary and secondary standards), potentiometers, and Mueller bridges calibrated periodically by the NBS or other qualified laboratory.
