Reliability Networks

A system in the area of oil and gas industry can form various types of configurations or networks in performing reliability analysis. Thus, this section is concerned with the reliability evaluation of such commonly occurring configurations or networks.

Another design question relates directly to the issue of function. The question is whether first to establish reliable networks and synthesize crystals based upon such networks, and then to modify the building blocks to introduce a desired function while maintaining the reliability of the network. Alternatively, one can take molecules with functionality built-in and then try to develop them, perhaps by minor synthetic modification into building blocks for a suitable network that will permit a functional crystalline material to be prepared. These issues have been examined in Section 7. 

One of the key elements of each distributed platform is communication between computer nodes and management of reliable network connections. All service-driven platforms are usually focused on communication protocols and service execution using a form of network middleware. However, most do not have a service-oriented operating system that deals with efficient management of services as platform commands, front-end programming (service scripting), and rehable runtime networking. 

Network Time Protocol (NTP)[26J is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. It would be the most appropriate solution to providing synchronised clocks between polling booths if we had a reliable network connection.

This is the simplest reliability network or configuration, and its block diagram is shown in Figure 3.6. 

This is another type of reliability network/configuration in which only one unit operates and k units are kept in their standby mode. The network/sys-tem contains a total of (k + 1) unifs as soon as the operating unit fails, the switching mechanism detects the failure and turns on one of the standby units. The system fails when all fhe sfandby units fail. The block diagram of a sfandby system with one operating and k standby units is shown in Figure 3.9.

The recognition ratios achieved by CBR systems developed as part of this project could not be bettered by either neural-network classifiers or rule-based expert system classifiers. In addition, CBR systems should be mote reliable than simple classifiers as they are programmed to recognise unknown data. The knowledge acquisition necessary to build CBR systems is less expensive than for expert systems, because it is simpler to describe the knowledge how to distinguish between certain types of data than to describe the whole data contents. 

The end users of CBR systems should in principle be able to maintain the case-bases themselves and use the systems for varying inspection types (within certain limits). Adaptation of neural-network based systems, though possible by end-users, is difficult to be done reliably. Adaptation of rule-based systems usually has to be done by the rule-base designer.

Problems involving routine calculations are solved much faster and more reliably by computers than by humans. Nevertheless, there are tasks in which humans perform better, such as those in which the procedure is not strictly determined and problems which are not strictly algorithmic. One of these tasks is the recognition of patterns such as feces. For several decades people have been trying to develop methods which enable computers to achieve better results in these fields. One approach, artificial neural networks, which model the functionality of the brain, is explained in this section. 

Neural networks have been applied to IR spectrum interpreting systems in many variations and applications. Anand [108] introduced a neural network approach to analyze the presence of amino acids in protein molecules with a reliability of nearly 90%. Robb and Munk [109] used a linear neural network model for interpreting IR spectra for routine analysis purposes, with a similar performance. Ehrentreich et al. [110] used a counterpropagation network based on a strategy of Novic and Zupan [111] to model the correlation of structures and IR spectra. Penchev and co-workers [112] compared three types of spectral features derived from IR peak tables for their ability to be used in automatic classification of IR spectra. 

Some of the features of GO (EPRI NP-3123) are given in Table 3.4.6-2. A GO model is networks GO operators to represent a system. It can be constructed from engineering drawings by replacing system elements (valves, switches, etc.) with one or more GO symbols. The GO computer code quantifies the GO model for system reliability, availability, identification of system fault sequences, and relative importance in rank of the constituent elements.

Canada, in response to extreme concerns regarding the reliability of the rapidly developing interconnected power networks in North America. NERC is a not-for-profit corporation owned by ten regional councils, whose members come from virtually all segments of the electric power industiy. Their parent companies account for virtually all the electrical energy supplied thronghout the United States, Canada, and northern portions of Baja California, Mexico. The various regional councils arc as follows ...

The North American electric power transmission system has been described as the largest, most complex machine ever built by humanity. It is a massive network of generating stations, transmission lines, substations, distribution lines, motors, and other electrical loads all interdependently linked for the conversion, transportation, and control of electrical energy. Approximately 60 percent of all energy utilized in the United States passes through the interconnected electric power system. The major goal of the system is to most efficiently and reliably deliver electric power from generating stations to residential, commercial, and industrial consumers. 

With the opening of the transmission network to all resource suppliers, many marketing entities entered the game in the mid-1990s. Many of these marketers are subsidiaries of already established gas suppliers. Some have been created solely for the electric industry. Still others have been formed from the utilities themselves. All of these etitities arc competition-motivated. Facility planning and reliability issues, while important to their business, are left to other organizations.

Undoubtedly, the properties of superabsorbent hydrogels occupy the key position in the problem under consideration. Being directly connected with the network formation reaction, they provide all necessary information about the details of this process. Also, the SAH properties are found to be the most reliable basis for understanding and predicting their behavior in real systems, i.e. in the soil, in contact with plants, in physiological media, etc.
