The simulator of power part of electric drive for research purposes of electric drives is under consideration in the paper. It is based on the software and hardware of National Instruments Company and includes mathematical model of converter, motor and load. The simulator is designed to setting up the electric drive and to explore the modes of its operation.

Plastic working technologies are frequently applied nowadays, as parts can be produced with larger productivity and smaller material loss compared to other technologies, at the same time the mechanical properties of parts are more favorable. Usually large tensile, pressure, bending or torsional forces, torques are required during plastic working. While pneumatic, hydraulic or electric energy is required to generate these. Used energy is determined by the losses of the energy required for working and that of energy conversion. The losses of working equipment are determined by mechanical losses and the losses of the energy converters applied, as well as by the manufacturing algorithm operating the working equipment. The advantage of electric driven working equipment over pneumatic and hydraulic driven ones is the better efficiency of energy converters, as well as the lower price of electric power. The disadvantage of electric converters is the large dimensions compared to hydraulic or pneumatic systems. Due to the development of electric servo drives the pneumatic and hydraulic drives are to be changed to electric drives in working equipment improving their control and accuracy features besides efficiency. In this paper the loss decreasing possibility of the working equipment with electric servo is investigated.

Geological samples typically contain many minerals (phases) with multiple element compositions. A complete analytical description should give the number of phases present, the volume occupied by each phase in the bulk sample, the average and range of composition of each phase, and the bulk composition of the sample. A practical approach to providing such a complete description is from quantitative analysis of multi-elemental x-ray images.With the advances in recent years in the speed and storage capabilities of laboratory computers, large quantities of data can be efficiently manipulated. Commercial software and hardware presently available allow simultaneous collection of multiple x-ray images from a sample (up to 16 for the Kevex Delta system). Thus, high resolution x-ray images of the majority of the detectable elements in a sample can be collected. The use of statistical techniques, including principal component analysis (PCA), can provide insight into mineral phase composition and the distribution of minerals within a sample.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.

Living cells naturally maintain a variety of metabolic reactions via energy conversion mechanisms that are coupled to proton transfer across cell membranes, thereby producing energy-rich compounds. Until now, researchers have been unable to maintain continuous biochemical reactions in artificially engineered cells, mainly due to the lack of mechanisms that generate energy-rich resources, such as adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). If these metabolic activities in artificial cells are to be sustained, reliable energy transduction strategies must be realized. In this perspective, this article discusses the development of an artificially engineered cell containing a sustainable energy conversion process.
