M any of the paper machine runnability problems that are difficult to detect, monitor, and control are caused by hydrophobic particles. These can be, for example, binder-rich particles in coated broke, wood pitch or stickies associated with recycled fiber. The most important characteristic indicating propensity for runnability problems has proven to be the size, or the increase in size, of hydr...

Every time we detect a part that is out of tolerance, the implication is that something went wrong in the machining process: either the operator made a mistake, or the machine tool did. A lot of the time, problems with the machine get blamed on the operator. Rather than expect the operator to compensate for every machine tool problem -at the expense of increased setup time and scrap -it makes m...

Virtual machine introspection (VMI) has formed the basis of a number of novel approaches to security in recent years. Although the isolation provided by a virtualized environment provides improved security, software that makes use of VMI must overcome the semantic gap, reconstructing high-level state information from low-level data sources such as physical memory. The digital forensics communit...

This paper outlines the development of a knowledgebased expert system for diagnosing machine tool failures. The complexity of machine tool failures and the trouble shooting procedures are deployed. The diagnostic knowledge is acquired from analysis of the troubleshooting and repair reports as well as from interviews with diagnosis engineers. The knowledge base is built using the object oriented...

−− Servocontrol loops are an important component in the control architecture of machine tools. Such loops manage the axes based on requirements of velocity, position, and acceleration. The success of modeling and control techniques applied to this level sets the basis for production of parts with high quality as well as cycle time reduction. First, an introduction is presented for the three may...

The LOGON MT demonstrator assembles independently valuable general-purpose NLP components into a machine translation pipeline that capitalizes on output quality. The demonstrator embodies an interesting combination of hand-built, symbolic resources and stochastic processes.

The choice of the machine tools is one of the considerations of manufacturing companies which depend primarily on machining process, by deciding how a finished product will be manufactured. The activity of tools choice is established in geometry of machining features, but it also has a direct impact on workability and execution of machine-tool. We propose in this paper an integration module of ...

The reconfigurable vibrating screen (RVS) machine is an innovative beneficiation machine designed for screening different mineral particles of varying sizes and volumes required by the customers’ through the geometric transformation of its screen structure. The successful RVS machine upkeep requires its continuous, availability, reliability and maintainability. The RVS machine downtime, which c...

Intelligence of machine tools is not conditioned only by application of modern control systems, sensors and other active components. The application of new methods of modelling, that is intelligent design of machine tools and to purposefully predict its properties, is also very effective. Machine tool development for high speed and highly precise cutting demands employment of advanced simulatio...
