Component modular

Complex products can be understood as a network of components that share technical interfaces (or connections) in order to function as a whole. Component modularity is defined based on the lack of connectivity between components [4]. Technically (Fig. 14.1), it can be expressed with three measures (a) how components share direct interfaces with adjacent components, (b) how design interfaces... 

In conclusion, a graph is presented (Fig. 4.6). The dimension of component modularity has not been the subject of discussion however, as it has been treated before and is a vital aspect of the entire chapter, this dimension is also included in the graph. 

Major economic improvements for SMART can be summarized as system simplification, component modularization, factory fabrication, direct site installation of components and reduced construction time. The integral arrangement of the primary reactor systems requires only a single pressurized vessel and removes large-sized pipes connecting primary components. The adoption of simplified passive systems provides a net reduction in the number of safety systems and drastically reduces the number of valves, pumps, wirings and cables, pipes, etc. 

The key words of small and modular make the small modular reactors (SMRs) different than other reactors. Small denotes the reactor s decreased power size. Modular denotes (1) the primary coolant system (such as the reactor (RX) component in a light water SMR) enveloped by a pressure boundary and (2) modular construction of components. Modular design requires compact architecture that is built in facility. For instance, the term of modular for a light water SMR (LW-SMR) is used for the RX, since it covers the reactor core and primary coolant system so that the overall power of a power plant can easily be increased by increasing the modular units.

MODULAR SCANNER SYSTEM System Component Description. 

The following section presents three examples of NDE scanners build from modular searmer components. 

A modular scanner system for NDE has been developed. It consists of a selection of individual electronics and motor module components, supported by scanner configuration and control software. The modules are used as standard building blocks for construction of job specific, dedicated scanners as well and general purpose scanners. The use of modular scanner components significantly reduce the work, time and cost not only for the design and manufacture but also for establishing documentation and ensure compliance with the relevant EU-directive requirements. 

The Advanced Inspection Robot - AIR-1 is a portable (weight approx. 25 kg.) 6-axis articulated elbow type robot manipulator with 6 degrees of freedom. It is build from standard motor and control module components from FORCE Institutes Modular Scanner System and is controlled from within the UltraSlM/UlScan graphical generic robot control application. 

Modularity. Modularity requires that designs be divided into physically and functionally distinct units to faciUtate removal and replacement. Modularity allows design of components as removable and replaceable units for minimum downtime. 

The head of the femoral component then articulates with an ion-bombarded, HDPE, high walled, acetabular liner which fits iato a screwed ia, machined, titanium, chromium—cobalt—molybdenum or vanadium—aluminum metallic alloy hydroxyapatite-coated acetabular shell/cup. Each of the separate parts of the modular system for total hip arthroplasty is manufactured ia several different sizes. 

To have a modular construction with a wide choice of module sizes for optimum utilization of the usable area in each vertical panel, which is normally 1800 mm as illustrated in Figure 13,32, The general practice is to have the module sizes in the ratio of 1/6 (300 mm), 1/4 (450 mm), 1/3 (600 mm) and 1/2 (900 mm), etc. Some manufacturers, however, supply 1/8 (225 mm) and 1/9 (200 mm) size of modules when the sizes and number of components for a module are less and can be accommodated in such a small module size. For critical installations, however, such as for a refinery or a petrochemical plant or for the essential services of a powergenerating station or installations that are in humid conditions or are contaminated, it is advisable to have a module size no smaller than 1/6 (300 mm)...

An important feature of the typical system is its modularity. The most powerful EMCS installations have all three components, but often only a single module is necessai y for simple applications, such as controlling a single air-conditioning unit, or for most applications in the residential sector. Thus local and control modules arc capable of stand-alone operation without higher-level components. The functions,... 

Depending upon the required duty and the site, units may be shop assembled or of modular construction. Site-erected units may be designed to have their main components arranged to fit in with the space available. 

This specialized form of supply air system is often used in large open industrial spaces. It comprises a modular system of components that can be built up into simple systems. A typical system might have a roof inlet cowl, a recirculation damper, a heater battery, a fan, one or two outlet grilles and short sections of connecting ductwork, and would handle airflows up to 3-4m /s, depending on size. A number of individual systems would be used to provide the total airflow required in the space (Figure 28.4). Systems are normally manufactured with aluminum casings to reduce the roof load. 

Modularity. Since we would like to use the sufficient theory in a variety of contexts and problems, we need a theory that was easy to extend and modify depending on the context. In our state-space formulation the sufficient theory is couched in terms of constraints on variables. This theory gives us the opportunity to modularize its representation, partitioning the information necessary to prove the looseness of one type of constraint from that required to prove the looseness of a different constraint type. The ability to achieve modularity is a function not only of the theory but also of the representation, which should have sufficient granularity to support the natural partitioning of the components of the theory. 

Rinard dedicated his research to a detailed analysis of methodological aspects of a micro-reactor plant concept which he also termed mini-plant production [85] (see also [4, 9, 10] for a commented, short description). Important criteria in this concept are JIT (Just-in-time) production, zero holdup, inherent safety, modularity and the KISS (keep it simple, stupid) principle. Based on this conceptual definition, Rinard describes different phases in plant development. Essential for his entire work is the pragmatic way of finding process solutions, truly of hybrid character ]149] (miniaturization only where really needed). Recent investigations are concerned with the scalability of hybrid micro-reactor plants and the limits thereof ]149], Expliddy he recommends jointly using micro- and meso-scale components.
