of molten aluminium with a sodium, barium and aluminium fluoride electrolyte. The resulting aluminium has a purity of 99.99%. Electric power represents about 20% to 40% of the cost of producing aluminium, depending on the location of the smelter. Aluminium production consumes roughly 5% of electricity generated in the U.S. Smelters tend to be situated where electric power is both plentiful and inexpensive, such as the United Arab Emirates with excess natural gas supplies and Iceland…

ABSTRACT This work has as objective provides a general vision of the characteristics and resources today available in the market of Programmable (CLP's) Logical Controllers, as well as, his/her application in industrial nets with supervisory systems in the several fields of the industrial automation and control of processes. CLP's are very diffused in the areas of control of processes or of automation. In the first case the application feels in the industries of the continuous type

sections of this book, analyses are made of devices such as turbines and pumps through which mass flows. These analyses can be conducted in principle by studying a particular quantity of matter, a closed system, as it passes through the device. In most cases it is simpler to think instead in terms of a given region of space through which mass flows. With this approach, a region within a prescribed boundary is studied. The region is called a control volume. Mass may cross the boundary of…

they are not used in all military organizations and are only slowly being commercially released [2]. Current applications include noise propagation in industrial air handling systems, reduction of propeller noise in aircrafts and tonal noise from electric power, as well as isolation of vibration from noise radiating structures. Even with these applications, the transition of active noise control from the laboratory to the market is far from complete [4]. A hands-on implementation of…

object made up of an ensemble of particles continuously moving about their mean position within the object. A charged particle in the object oscillating with a frequency ν induces an oscillating electric field propagating outside of the object at the speed of light c (Figure 7-3). The oscillating electric field, together with the associated oscillating magnetic field, is an electromagnetic wave of wavelength λ = c/ν emitted by the object. The electromagnetic wave carries energy; it…

sem dúvida ter a certeza que é uma ferramenta que agrega e cria muitos benefícios. organizações que são consideradas referências em excelência no mundo dos negócios; grupos empresariais como: 3M Company, American Express Company, Toyota, General Electric, Jhonson & Johnson, e a Xerox Company, que talvez foi uma das organizações que mais divulgou os benefícios que consegui com a utilização do benchmarking. Listar todos os benefícios que benchmarking proporciona as organizações, é…

studied the magnetic field around a conductor carrying a DC electric current, and established the basis for the magnetic field concept in physics. He discovered electromagnetic induction, diamagnetism and electrolysis. He established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. [2] [3] His inventions of electromagnetic rotary devices formed the foundation of electric motor technology. As a chemist, Faraday…

fornecedores tem de ser fundamentada na visão estratégia que uma organização possui para a relação com os seus fornecedores, devendo ambas as entidades partilhar a mesma ética profissional e os mesmos compromissos de melhoria e desenvolvimento. A empresa General Dynamics (GD), numa brochura sobre o seu programa de monitorização do desempenho dos seus fornecedores, apresenta como principais benefícios promover a competitividade entre os fornecedores, aumentar os níveis de satisfação mas…

qual a AT&T concordou em limitar suas atividades ao trabalho governamental e ao negócio regulamentado do sistema telefônico nacional. A AT&T era, então, a maior empresa do mundo empregando aproximadamente 1 Milhão e com mais propriedades do que General Motors, Exxon e Mobil juntas , e os oficiais federais estavam cada vez menos à vontade com o fato de que ela cuidava de 80% do mercado de telecomunicações em expansão dos EUA. Enquanto os procedimentos legais arrastavam-se, a AT&T…
