The Computer Numerical Control (CNC) machine represents a turning point in today's production which has high requirements for product accuracy. CNC enables flexibility work and time saving also reduces the required accuracy control. Moreover, are used several activities, most often turning, drilling milling operations. Usually, productivity of any can be increased thanks to minimization non-pro...

Purpose: The objective of the researches presented in the paper is to investigate, in laboratory conditions, the application possibilities of the proposed system for tool wear monitoring in hard turning, using modern tools and artificial intelligence (AI) methods. Design/methodology/approach: On the basic theoretical principles and the use of computing methods of simulation and neural network t...

The idea of connecting the human brain to a computer or machine directly is not novel and its potential has been explored in science fiction. With the rapid advances in the areas of information technology, miniaturization and neurosciences there has been a surge of interest in turning fiction into reality. In this paper the authors review the current state-of-the-art of brain-computer and brain...

Games of chance are often used as conceptual models of random processes in nature. For example, an exhibit on the heart in Chicago's Museum of Science and Industry includes a kind of pinball machine. After the balls bounce somewhat randomly through this machine, they fall into bins symbolizing the different states of health of one's heart. One can bias the outcomes for better or for worse by tu...

For the investment decision for new production equipment it becomes more and more common to guarantee the total amount of life-cycle-costs (LCC). In the research project "LoeWe", funded by the German Federal Ministry of Education and Research (BMBF), methods are developed to minimize life cycle costs in the development, operation and recycling phase. Exemplarily the development of an innovative...

The technology of ultra-precision machining, spanning almost three decades, has only in recent years experienced major advances in machine design and, subsequently, performance and productivity. In the 1970’s, ultra-precision machining techniques were successfully adopted for the manufacture of computer memory discs used in hard drives, and also photoreceptor components used in many photocopier...

As virtualization continues to become increasingly popular in enterprise and organizational networks, operators and administrators are turning to live migration of virtual machines for the purpose of workload balancing and management. However, the security of live virtual machine migration has yet to be analyzed. This paper looks at this poorly explored area and attempts to empirically demonstr...
