  • For thirty years or more the expressions “Correlation of the Physical Forces” and “The Conservation of Energy” have been common, yet few persons have taken the necessary pains to think out clearly what mechanical changes take place when one form of energy is transformed into another. Since Tyndall gave us his book called Heat as a Mode of Motion neither lecturers nor text-books have attempted to explain how all phenomena are the necessary outcome of the various forms of motion.

  • Abstract In 1963 Atiyah and Singer proved the famous Atiyah-Singer Index Theorem, which states, among other things, that the space of elliptic pseudodifferential operators is such that the collection of operators with any given index forms a connected subset. Contained in this statement is the somewhat more specialized claim that the index of an elliptic operator must be invariant under sufficiently small perturbations.

  • The design, implementation, and use of grammar forma]isms for natural language have constituted a major branch of coml)utational linguistics throughout its development. By viewing grammar formalisms as just a special ease of computer languages, we can take advantage of the machinery of denotational semantics to provide a precise specification of their meaning.

  • This Instructor’s Manual is intended to accompany the fourth edition of Electric Machinery Fundamentals. To make this manual easier to use, it has been made self-contained. Both the original problem statement and the problem solution are given for each problem in the book. This structure should make it easier to copy pages from the manual for posting after problems have been assigned.

  • An updated approach to reference frame analysis of electric machines and drive systems Since the first edition of Analysis of Electric Machinery was published, the reference frame theory that was detailed in the book has become the universally accepted approach for the analysis of both electric machines and electric drive systems. Now in its second edition, Analysis of Electric Machinery and Drive Systems presents, in one resource, the application of this theory to the analysis, simulation, and design of the complete drive system including the machine, converter, and control....

  • The names Bloch and Geitner are synonymous with machinery maintenance and reliability for process plants. They save companies like Dow and Equilon millions of dollars a year by extending the life of rotating machinery in their plants. Extending the life of existing machinery is the name of the game in the process industries, not designing new machinery. This series by Bloch and Geitner was the first and is still the best, most comprehensive source for doing just that.

  • Machinery reliability management in the process industries can be divided into three phases: equipment selection and pre-erection reliability assurance, preparation for effective startup, and post-startup reliability assurance and maintenance cost reduction. All of these phases are important; they are intertwined and merit equal attention. The techniques and procedures described in this text cover essential elements of each phase; they have been critically examined and have led to substantially improved reliability and maintenance efficiencies.

  • The authors use their decades of experience and draw upon real-world examples to demonstrate that the application of their techniques provides a basis for equipment management, uptime maximization, and reduced maintenance costs. The text explores reliability assessment techniques such as Failure Mode, Effect Analysis, and Fault Tree Analysis of commonly encountered rotating machinery. These are all highly effective techniques that the engineer can apply to maximize uptime and thereby maximize production and profitability.

  • The collective load is the basis for determining the average speeds (2,387 min–1) and the average driving speed (111 km/h). For each of the load cases the tooth load acting on the pinion and the reaction loads from the bearings have to be calculated both for forward and backward motion (percentage times 50 % each). In addition to these forces, the bearings are subjected to loads due to the rotor weight, the unbalanced magnetic pull, unbalanced loads and rail shocks. Of these loads only the rotor weight, GL, is known; therefore, it is multiplied by a supplementary factor fz = 1.

  • A humanist educational model can be defined as a system in which human values, dignity, reason and fulfilment in harmony with nature predominates. By contrast, the present system is based on utilitarian values to transform knowledge into commodities. Within this context we see the dehumanization of our children, young people and students. I assume that the function of higher education is to reify ruling class values into the social consciousness of students, and to train students to serve the capitalist machinery.
