Opis:
Industry 4.0 (I4) as a concept offers powerful opportunities for many businesses. The set of Industry 4.0 technologies is still discussed, and boundaries are not perfectly clear. However, implementation of Industry 4.0 concept becomes strategic principle, and necessary condition for succeeding on turbulent markets. Radio Frequency Identification (RFID) was used before I4 emerged. However, it should be treated as its important part and even enabler. The question arises how adoption of RFID was impacted by I4 paradigm. Therefore, to answer this question a set of technology management tools was selected and applied to forecast RFID potential development in forthcoming years. Moreover, case studies were conducted for technology management tools and their applications for RFID for qualitative discussion of its relevance. It aimed to prove that existing toolset should be applied for modern technologies related to I4. Tools were proven to be necessary and successful. However, some specific challenges were observed and discussed.

Opis:
To comprehensively investigate the diversity of a chamfer technology and a convex roll technology under the same soft reduction process (i.e., section size, reduction amount, casting speed and solid fraction), a three-dimensional mechanical model was developed to investigate the effect of the chamfer profile and roll surface profile on the deformation behavior, cracking risk, stress concentration and reduction force of as-cast bloom during the soft reduction process. It was found that a chamfer bloom and a convex roll can both avoid the thicker corner of the as-cast bloom solidified shell, and significantly reduce reduction force of the withdrawal and straightening units. The convex profile of roll limits lateral spread along bloom width direction, therefore it forms a greater deformation to the mushy zone of as-cast bloom along the casting direction, the tensile strain in the brittleness temperature range (BTR) can obviously increase to form internal cracks. The chamfer bloom is much more effective in compensating the solidification shrinkage of mushy zone. In addition, chamfer bloom has a significant decrease of tensile strain in the brittleness temperature range (BTR) areas, which is expected to greatly reduce the risk of internal cracks.

e-Choupal is an initiative of Indian Tobacco Company (ITC) Limited which came into existence in the year 2000 with an objective to link rural farmers via the Internet to procure agricultural products. Traditionally, agricultural commodities were procured in mandis, major agricultural marketing centers in rural areas, where the middleman make most of the profit. These middlemen used unscientific and unfair means to judge the quality and set the price of the product and therefore there has been less incentive for the farmers to invest and produce good quality output. With the formation of e-Choupal, the farmers were given a choice to sell their products freely diminishing the influence of the middlemen. This initiative also addressed issues like fragmented farms, weak institutions, and information asymmetry amongst farmers.This paper examines and evaluates the business model of ITC e-Choupal and studies the acceptance of this business by the farmers.

Opis:
We derive an efficient algorithm for the steady state analysis of fibre lasers operating under cascade pumping scheme by combining the shooting method with the Newton-Raphson method. We compare the proposed algorithm with the two standard algorithms that have been used so far in the available literature: the relaxation method and the coupled solution method. The results obtained show that the proposed shooting method based algorithm achieves much faster convergence rate at the expense of a moderate increase in the calculation time. It is found that a further improvement in the computational efficiency can be achieved by using few iterations of the relaxation method to calculate the initial guess for the proposed shooting method based algorithm.

Opis:
Wide scale, European, infrastructural research projects on accelerator science and technology are under realization since 2003. CARE project was realized during the period 2003/4-2008, and next EuCARD during 2009-2013. Now during 2014-2017 there is successfully continued EuCARD² - Enhanced European Coordination of Accelerator R&D. European accelerator R&D community prepares next continuation of the EuCARD inside the Horizon 2020. The paper presents the work developments of EuCARD. Several institutions from Poland are participating in EuCARD: NCNR in Świerk, IChTJ, technical Universites in Łódź, Wrocław and Warsaw. Realization of the project during the last 12 years gave numerable and valuable results combined with essential modernization of the European research infrastructures. From the point of view of domestic interests, where we do not have large research infrastructures, the considerable benefits are associated with the participation of young researchers from Poland - engineers and physicists, in building of the top research infrastructures. Due to such participation, high technologies are developed in several centres in the country. The EuCARD project organizes annual meetings summarizing periodically the R&D advances. The EuCARD AM2015 was held in Barcelona in April.

avant-garde czech poetry
Opis:
Literary scholars generally attribute a fascination with technology to the avant-garde poets, sometimes even writing about the typical avant-garde cult of the machine and civilisation. The example of Neumann’s poetry, however, shows that the purpose of these avant-garde activities need not have been a glorification of technology. Rather, they were interested in the subjugation of technology, because in the early 20th century it still aroused widespread terror. In Neumann’s famous book Nové zpěvy, this process of taming technology takes on an extremely sophisticated form: it proceeds from a state of suspicion about machines on to full acceptance of the major civilisational changes at the turn of 20th century. The detailed analyses carried out in this article show that the Czech author’s poems are never an expression of delight about technology alone, but an expression of delight at a world in which the sphere of technology and the natural world are one, harmonious whole. This means that the affirmation of technology is not possible without the prior affirmation of life itself.

Opis:
Crushing processes taking place in high-pressure grinding rolls devices (HPGR) are currently one of the most efficient methods of hard ore size reduction in terms of the energy consumption. The HPGR products are characterized by a fine particle size and the micro-cracks formation in individual particles, which appears in downstream grinding processes, decreasing their energy consumption. The purpose of the paper was to analyze the effectiveness of a ball mill grinding process and flotation operations depending on the changeable conditions of run of the HPGR crushing process. The research programme carried out included crushing tests in the laboratory scale HPGR device at various settings of the operating pressure volume and selected qualitative properties of the feed material (i.e. particle size distribution). On the basis of obtained results the models, defining the grinding process effectiveness as a function of changeable conditions of HPGR process run, were determined. Based on these models the optimal grinding time in a ball mill was specified which is, in turn, the basis for optimization of operation the technological comminution circuits for a given material type. The obtained results proved that the application of HPGR devices in given copper ore comminution circuit may improve the effectiveness of downstream grinding process what leads to improvement of the entire circuit work efficiency through decreasing the process energy consumption and enhancing the product size reduction.

Opis:
Today, computerization of the Assessment Program is a norm, numerous advantages of Computer-Assisted Assessment (CAA), both formative and summative, can be enlisted. Motivating students to systematic work and Self-Regulated Learning seems to be the biggest challenge faced by the teacher. This motivation can be reached by providing students with clear information that shows an evident effectiveness of formative quizzes, undisputable correlation between student engagement in taking formative quizzes and the final exam result. It is proposed to evaluate this effectiveness quantitatively in the field of Information Theory, using the Discrete Memoryless Channel description of relationship between the set of quizzes taken and the set of exam results. The Case Study is presented and if proves high correlation between these two sets.

Opis:
General lighting is the most common way of illuminating interiors and the source of electricity consumption in buildings. This fact forces the search for lighting solutions effective both for people and the environment. In this study the impact of room and luminaire characteristics on general lighting conditions and energy efficiency in interiors is considered. In rooms of different sizes and reflectances, seventeen luminaire types with various light distributions were arranged in uniform layouts. The levels of average illuminance, uniformity and normalised power density related to two horizontal working planes were calculated. The impact of working plane reduction, room index and reflectances, lighting class and luminous intensity distribution of luminaire on the considered parameters was investigated. The use of the reduced working plane resulted in the increase in the average illuminance (7.7% on average), uniformity (33% on average) and normalised power density (23% on average). The impact of the room index and lighting class on the average illuminance and normalised power density was significant while the impact of the luminaire luminous intensity distribution and room reflectances was low. The normalised power density levels of the general electric lighting in interiors, with luminaire luminous efficacy of 100 lm/W, are in the following range: 1.08‒3.42 W/m2 per 100 lx. Based on these results a normalised power density level of 2 W/m2 per 100 lx is recommended for designing and assessing the new general electric lighting systems in buildings.
