Logic and Engineering

Reasoning tasks can be achieved by good formal languages, where by formal languages has precise syntax and semantics. Reasoning tasks are important when there are inferences and hence a further condition is required on our notion of formal language, namely it should provide a calculus defining some kind of consequence relation. [Pg.13]


Hence, without any number and even formulation rationally thinking mind can draw all possible rational information and knowledge as explained above. Of course, s/he uses philosophy of engineering and logical information as one senses, but in the case of philosophy of engineering fundamentals and logical principles... [Pg.170]

The PSM Rule requires that a what-if analysis be performed by a team with expertise in engineering and process operations. It must include at least one employee experienced in the process, and one knowledgeable in the use of the analysis method. For simple processes, two or three people may be assigned to perform the analysis. However, larger teams may be required for more complex processes. When a large team is required, the process may be divided logically into smaller pieces, and a subset of the team may analyze each piece. [Pg.47]

Release data related to the SCADA network only on a strict, need-to-know basis, and only to persons explicitly authorized to receive such information. Social engineering, the gathering of information about a computer or computer network via questions to naive users, is often the first step in a malicious attack on computer networks. The more information revealed about a computer or computer network, the more vulnerable the computer/network is. Never divulge data revealed to a SCADA network, including the names and contact information about the system operators/administrators, computer operating systems, and/or physical and logical locations of computers and network systems over telephones or to personnel unless they are explicitly authorized to receive such information. Any requests for information by unknown persons need to be sent to a central network security location for verification and fulfillment. People can be a weak link in an otherwise secure network. Conduct training and information awareness... [Pg.134]

The contents of a knowledge base, the facts and rules, or heuristics about a problem will be discussed shortly. The problem-solving and inference engine is the component of the system that allows rules and logic to be applied to facts in the knowledge base. For example, in rule-based expert systems, "IF-THEN" rules (production rules) in a knowledge base may be analyzed in two ways ... [Pg.4]

The disciplines of engineering and quality control have long recognized the principles of root cause analysis. Some process safety tools for root cause analysis have been borrowed from these disciplines. For example, fault tree analysis was developed as an engineering tool, but its logic tree structure has been adapted to meet process safety requirements. [Pg.45]

The first intent of this text is to update the fundamental principles of the operation of chemical reactors in a brief and logical way. We also intend to keep the text short and cover the fundamentals of reaction engineering as briefly as possible. [Pg.5]

Abstract—Written in the form of a conversation between a mathematician, an engineer, and a palceographer, this paper attempts to explore the value of complementary viewpoints the physical and mathematical in modelling, the logical and the imaginative in mathematics, the historical and the artistic in palceography. [Pg.374]

Waterside problems that lead to decreases in efficiency and material deterioration can be caused by a variety of mechanisms, such as electrochemical corrosion and deposition of foulants. These problems can be exacerbated by low flow, poor operational practice, process contamination, or specific stresses. It is also important to try to determine cause and effect relationships in order to provide a logical and practical water treatment solution. Such a solution will usually involve some form of cleaning, plus a combined engineering and chemical action plan. Inspection may be made easier by the use of a Boroscope or similar optical/video recording device. The color, texture, and quantity of all deposits should be noted, measurements of pits taken, and microbiological contaminants analyzed. It may be useful to conduct biocide efficiency tests on bacterial slimes. The period when a heat exchanger is open for inspection may be an opportune time for the permanent installation of ports for corrosion-monitoring probes. [Pg.22]

Easy and logical way of document flow (production engineering, quality assurance, production). [Pg.498]

Offering an inside look at the logic behind the formation of polyurethane components, Castable Polyurethane Elastomers enables material scientists, engineers, and chemists to understand the total production process and reproduce the procedures to achieve desired results. [Pg.257]

The universal character of the LbL method has catalyzed the introduction of the method for a wide range of bioapplications. Proteins (enzymes) [30-33], polypeptides [34], polysaccharides [35], lipids [36, 37], nucleic acids [38-42], viruses [43], inorganic particles, and crystals [44] have been embedded in the films. Use of these compounds makes the films attractive for biorelated applications such as biosensors, drug delivery, tissue engineering, and biocoatings. Biological [45, 46] and nonbio-logical [21, 47 19] applications of LbL films are reviewed in the literature. [Pg.137]

Since ferroelectricity was discovered in 1921 it has been obvious to many scientists and engineers that the two stable polarization states +P and P could be used to encode the 1 and 0 of the Boolean algebra that forms the basis of memory and logic circuitry in all modem computers. Yet until very recently this has been unsuccessful. In fact, although ferroelectric materials are used in a wide variety of commercial devices, it has until now always been the case that some other property of the material - especially pyroelectricity or piezoelectricity - is the characteristic actually employed. Ironically, no devices using ferroelectrics have actually required ferroelectricity to work. [Pg.329]
