    • NEURAL NETWORKS FOR DEFECTIVENESS MODELING AT ELECTRON BEAM WELDING

      pg(s) 5-8

      This paper considers the process electron beam welding in vacuum of stainless steel 1H18NT. Neural network based models are developed and used for the description of the defectiveness, depending on the process parameters – electron beam power, welding velocity, the distance between the main surface of the magnetic lens of the electron gun and the beam focusing plane and the distance between the main surface of the magnetic lens of the electron gun and the sample surface. Neural network (NN) models, based on a multi-layered feedforward neural network, trained with Levenberg-Marquardt error backpropagation algorithm are compared with NN models, based on Pattern recording neural network, trained with Conjugate Gradient Algorithm. The neural networks are trained, verified and tested using a set of experimental data. The obtained models are implemented to predict areas of process parameters, where the appearance of defects is most probable and the location of welding regimes that should be avoided.

This paper acknowledges the important changes which are occurring in the security of the ICT systems in the organizations as a consequence from the transfer to the cloud services.

      Traditionally, IT is positioned behind the firewall of any organization and all servers, virtualized or not, are specific as a service for any business. The authority which supports the security systems could choose the components for security among multiple proved products – firewalls, antivirus systems, servers, updates management, proxy servers, etc. In this way is guaranteed the high level of control upon the security of IT environment and the requirements of different standards for security.

    • VARIOUS TECHNIQUES IN SOFTWARE APPLICATIONS FOR 3D VISUALIZATION AND EVALUATION OF BIOISOSTERIC MOLECULES

      pg(s) 21-24

      The best – known software applications for 3D visualization and evaluation of bioisosteric molecules will be compared. The software applications are based on parameters, which can be divided mainly into two directions – emphasizing electrostatic properties, wave functions and presence of electrons in different energy states, and QSAR – based – quantitative methods – empirical examination of molecules, which use mainly statistical data collection, thus evaluating the properties of molecules through regression models to investigate similarity. The first group of innovative methods are superior, because of their analytical purposes that are not mining blindly for bioisosterism through empirical statistical data, but analytically detect similarities according to molecules’ shapes. In conclusion – the use of GPUs for parallel processing of matrix-based operation – for the calculations of quantum vectors – would lead to repeated acceleration of the speed of these calculations. Finally, this study demonstrates the GPU as another factor, which is important for the improvement of the evaluation methods of studying and visualization of molecular similarity.

    • BALANCE CONTROL OF SEGWAY ROBOTS USING ADAPTIVE-ROBUST CONTROLLER

      pg(s) 38-41

      Due to its compatibility and functionality, segways have been widely used in many countries. It was first introduced in December 2001.Yet, segway robots are faced with problems such as friction and external disturbances. Therefore, some controllers are designed to overcome with these problems. In previous studies, traditional controllers are used to balance a two-wheeled segway robot. The aim of this study is to minimize the trajectory tracking error. Due to external disturbances, such as wind, force and torque, robot parameters cannot be calculated exactly. Hence, the parameters of the robot are assumed to be unknown. In such situations, adaptive and robust controllers give better results. Adaptive and robust control laws were examined and adaptive-robust system was designed for the segway robot. Then Lyapunov function was defined and this adaptive-robust controller was derived from the Lyapunov function. And this control system applied to a two-wheeled segway robot model.

    • PROBLEM AREAS OF KNOWLEDGE IN A KNOWLEDGE ORGANISATION

      pg(s) 53-59

      A knowledge organisation should constantly expand and grow in order to survive in today’s competitive environment. One of the key opportunities to do so is allowing employees to use the accumulated knowledge. Organisations should enable employees to share their knowledge, while employees should be able to communicate and collaborate voluntarily and immediately, create new knowledge and accumulate individual knowledge. Although the need for knowledge is clear, knowledge movement at all stages of the knowledge life cycle is characterised by leakage, depreciation, dependence and trust. The article aims to review scientific literature and analyse knowledge issues in a knowledge organisation. To achieve this aim the following objectives have been set: analysing the concept of knowledge as a key resource in an organisation, examining the concept of organisation using a systematic approach and giving a critical overview of the scientific literature on this issue, justifying the need for knowledge at different levels and identifying problematic aspects of knowledge in a knowledge management process. The research applies methods of logical analysis, abstraction and synthesis.
