The article focuses at technology development of the vertical asymmetric rolling and combined process of vertical asymmetric rolling and plastic bending. It has been shown that vertical asymmetric rolling peculiarity relates to the presence of a mixed zone, in which friction forces on contact roll surfaces are directed are differently. Experimental research showed serious drawbacks in the rolling technology caused by the growth of dynamic loads arising at the moment of plate contact with the bending roller. For solving the problem it was proposed to make the roller position motile to allow its movement along the required trajectory. The application of the motile roller helps to reduce dangerous torque differentiation at working rolls by the value of 1,5-2,5 compared with the rigidly fixed roller. The most effective bending roller trajectory is a second-order curve that is convex parabola.

Purpose The purpose of this paper is to develop an EU sociotechnical systems (STSs) map to represent a harmonised concept of operations (CONOPS) as a future development platform for technologies used in multi-services emergency responses to chemical, biological, radiological and nuclear (CBRN) incidents. Design/methodology/approach AcciMaps were developed to locate where technologies are currently used, and opportunities for new technologies. The AcciMaps were iteratively co-designed with end users (fire, ambulance, police and military) across three EU countries (the UK, Finland and Greece). Data were collected using document analysis and interviews with senior ranking (Gold or Silver Command level) representatives of the participating end users. Findings Despite differences in terminology and between service sectors, consensus was achieved for the command structures (Gold, Silver and Bronze), and Hot Zone responders (specialist blue light responders and blue light responders (BLR)). A control room was included as the communication spine. BLR activities were limited by their scope of practice and available equipment, for example, breathing apparatus. The harmonised EU AcciMap offers a high-level STSs map of CBRN response. Critical segments have been identified which offer opportunities for technology developments that can add value in terms of response capabilities (e.g. tag and trace). Originality/value A large scale major CBRN incident may need cross-border and cross-professional engagement where efficient interoperability is vital. This research is the first EU consensus of a STS map for CONOPS. It supports future research for technology development, e.g., detection and decontamination equipment design and use, communication, diagnosis and response technologies.

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.

The problems of multifold increase of technological potential of developing countries are considered in the article. To solve them, i.e. to organize effectively tapping into global knowledge and their absorption, the performance of two diffusion channels is considered: open knowledge transfer and commercial knowledge transfer. The models of technological catching-up are investigated. Two of them are found to give an opportunity of effective use of international competition and global technology knowledge as a driver of technology development.

In Science and Technology Development BCI plays a vital role in the field of Research. Classification is a data mining technique used to predict group membership for data instances. Analyses of BCI data are challenging because feature extraction and classification of these data are more difficult as compared with those applied to raw data. In this paper, We extracted features using statistical Haralick features from the raw EEG data . Then the features are Normalized, Binning is used to improve the accuracy of the predictive models by reducing noise and eliminate some irrelevant attributes and then the classification is performed using different classification techniques such as Naïve Bayes, k-nearest neighbor classifier, SVM classifier using BCI dataset. Finally we propose the SVM classification algorithm for the BCI data set.
