The University of Bihać is a public institution of higher education founded on 28 July 1997, in Bosnia and Herzegovina. The seat of the university is located in the Kulina bana street 2/II.The origins of higher education in this region go back to en earlier date. In 1970, an office of the College of Engineering of Karlovac started its work here, and the Department of Engineering at the College of Engineering in Bihać was established in 1975. A Department of Textile Technology was founded in 1979, as well as the College of Economy.In 2009, the university had 4,935 graduate students: 3,954 students graduated with college degree and 981 students graduated with faculty degree. In the academic year 2007/2008, 4,881 students were enrolled, 3,407 of which were full-time students and 1,474 part-time students. Since 2006/2007, students have been enrolled in studies according to the principles of the Bologna declaration. The implementation of this principle is burdened with many problems. However, considering the enrollment policy, classes are mostly conducted in line with the Bologna system. This means that class sizes are narrowed to the minimum number permissible, and as such, students are able to receive more direct feedback from teachers and lecturers. Wikipedia.

Among the plenty of educational software, therapeutic software for dyslexia is not so abundant. The paper considers two different approaches to development of software for supporting specific learning difficulties. One could be offering of visual end user programming tools to speech and language pathologists so that they could develop specific software applications customized for their patients. The other approach could be the engagement of students majoring in educational sciences who are studying informatics as their secondary discipline to develop applications. Paper presents concept of end user development environment aimed for speech and language pathologistsas well as educational pilot-applications developed by the students. © 2013 University of Zagreb.

In the tooling industry, there is often the need to repair damaged or worn out components, or to apply coatings on functional surfaces of tools. When depositing a material which properties are very different from the properties of the substrate material, difficulties, such as cracks, can occur. In this paper, we investigate the deposition of three different powders (Metco 15 E, Colmony 88 and VIM CRU 20) on cast irons and low carbon steel with the laser engineered net shaping (LENS™) technology. Coatings with a maximum of four layers were deposited with different process parameters. Although most bonds itself were of good quality, some coatings had numerous cracks. Preheating of the cast iron samples with the laser beam was used to reduce the number of cracks. In the preheating process, the surface of samples was partially melted in order to dissolve graphite nodules which were often the starting point of cracks. © 2012 Springer-Verlag London Limited.

To survive in the highly competitive global economy, manufacturing systems must be able to adapt to new circumstances. An important prerequisite for adaptation is the ability to learn, a process based on knowledge discovery and growth. The aim of this research is to uncover knowledge by examining a large volume of real-time manufacturing data collected during manufacturing operations and to use the insights gained to support decision-making and adaptive process control. The paper presents the concept of a self-learning autonomous work system. This concept introduces a learning loop into a manufacturing system composed of data acquisition, data mining (DM), and knowledge-building models. Two methods for DM are applied. A descriptive DM method enables discovery of patterns in data that may contribute to a better understanding of the manufacturing processes. A predictive process provides knowledge in the form of rules, which can then be used for enhanced decision-making. To illustrate the utility of the knowledge models, the concept of adaptive process control is introduced and implemented in a high pressure die-casting domain. A case study based on industrial data collected during die-casting operations provides a demonstration of the concept. © 2012 Springer-Verlag London Limited. Source

This article proposes asystem for theautomatic programming of a CNC milling machine by particle swarm optimization (PSO). In the presented research, each individual swarm particle presents a possible numerical control (NC) program. Voxel representation of machining area was used. Bresenham's algorithm was implemented, for the rasterization of the cuts. Optimisation with PSO was carried out within a voxelized machining area. The system automatically finds the NC program for optimal machining. The NC program guarantees an optimal selection of tools, the shortest possible work and rapid motions, and minimization of the manufacturing time, thus achieving a reduction in machining costs and increased productivity. Testing using test workpieces and 2.5 D milling confirmed the efficiency of the proposed approach. The proposed intelligent system is easily adaptable for programming other types of CNC machines by PSO. © 2013 Taylor and Francis Group, LLC. Source

The case study is the role of authenticity, as a possible element in the selection of the tourism product in the field of economics and education, and part sociology. As the theoretical sources and previous studies with the observed field results, that the different significance is attributed to the different groups of tourists as the authenticity of the tourist product, so we used a relationship to authenticity as a specific psychographic segmentation criterion of the tourism market. Using conjoint analysis in the study has done in the specific field of this area and in general the first time through the mentioned analysis. We remain with the inclusion of existing information about the opportunities and trends in the work of the tourism market, which is relevant to the processing of area, wanted to prove that authenticity of tourism offer has a significant influence on long-term economic success and provides a sustainable development of tourism destinations. For this we linked to some theoretical concepts, such as the price of tourism products, the level of education and defensible competitive advantage. We believe that the results of research will enable better understanding of the problem, and that will be useful guidance for designing and selling tourism products, and the positioning of tourist destinations.
