During our research, we focus on a less researched area in the development of autonomous vehicles. Automotive industry is turning more and more from conventional, internal combustion engine equipped vehicles to the electric cars. Today, electric driving is mostly limited to urban traffic, this is the area where range and refueling limits can be a real alternative. However, it is important to think of those who intend to use vehicle in longer distances, and hybrid technology can provide them a modern, environmentally conscious way of transport.
In this article, we describe the method of creating the fuel consumption influencing factors matrix, which is the starting point of our research. We studied relevant researches and based on refueling studies we created the matrix. Based on results of real tests, we determined the factor mix that are the basis of our fuel consumption prediction model. These results will be inputs of planning routes of autonomous vehicles with optimized refueling and fuel consumption.
The use of fluidized bed boilers in modern power engineering is a promising solution for clean and economically acceptable combustion of various fuels, including coal, biomass and waste, for the generation of electricity. The fluidized bed boilers are nowadays technically advanced and complex combustion facilities where all individual boiler elements are subjected to withstand continuous structural and thermal loads during their operation. Intensive loading of boiler elements can be quite easily linked with boiler operational safety and is quite often one of the main reasons for emergency shutdowns followed by necessary replacements of the damaged items. In case of industrial large-scale circulating fluidized bed boilers the frequency of unplanned shutdowns is also quite often affected by the hydrodynamics of the fluidized bed and some other parameters, such as the intensity of solids circulation, temperature, solids concentration, flue gas composition and velocity, solids accumulation and deposition, as well as the corrosion or erosion of heat transfer surfaces. The present paper briefly reports the results of authors investigation focused on the morphology and structure of some chosen elements (steel anchors) sampled from one of Polish circulating fluidized bed boilers. The anchors were degraded during boiler operation and lost their mechanical durability. In order to determine the reasons of anchors’ degradation chemical composition of the elements was determined with the use of a spark spectrometer SPECTROLAB and sample morphology was investigated with JEOL JSM-6610LV scanning microscope equipped with LaB6 cathode.
Steels of the ARMOX class belong into a group of the fine-grained, increased strength steels, which are manufactured by the quenching and low-tempering procedure, with intensive thermo-mechanical treatment at high temperatures. Combination of the heat and mechanical treatments provides for the fine grains and exceptionally good properties of these steels, while the low-tempering enables relatively high hardness and good ballistic properties. This is why the welding of these steels can negatively affect the material properties in individual zones of the welded joint, what could lead to worsening of the material's ballistic properties, as well. The model plates were welded with the specially prescribed technology; the joints were the but-joint, corner joint and the joint with the shielding plate. In this paper are presented results obtained from the ballistic tests of the plates welded by the prescribed technology; tests consisted of shooting with three types of live ammunition at different types of the welded joints.
In a knowledge-based economy, innovation resulting from R & D activities and subsequent management of their legal safety are of particular importance. Incorrect patent law can lead to abuse in the area of innovation security on a large scale through the activities of the NPE organization (patent trolls). This phenomenon is particularly noticeable in the US while in the EU it is at a negligible level.
The aim of the article is to demonstrate and prove by using comparative literature and documents analysis of US and EU, that inappropriate law leads to violations of innovation safety through the unhampered activity of patent trolls, while a change of the law to more restrictive law is a right step to reduce the patent trolling. On the other hand, the author proves that in an area with a less liberal definition of patentability, there are no many violations of innovation safety through patent trolling.
Health and safety at work have their legal basis in international and Polish law – source of law currently valid in Poland. For efficiently functioning system of health and safety at work it is necessary to build appropriate institutional environment. The purpose of the article is to analyse the institutional system of health and safety at work in Poland based on source of law currently valid in Poland and forming remarks de lege lata and de lege ferenda in this scope.
Currently, the conditions enterprises are operating in are marked by considerable instability. Thus the changes they may undergo are difficult to predict. Practitioners and theoreticians of management science point to various approaches to building competitive advantage. In the past few years, the focus has been put mainly on information and knowledge. According to advocates of the knowledge management concept, knowledge is of key importance to building competitive advantage and succeeding on the market. The issues of knowledge and how it is gathered, updated and applied are not new. The challenge for contemporary entrepreneurs is, however, how to manage knowledge in global enterprises. The aim of this study is to analyse the issue of knowledge management in a company which based its development on expansion into foreign markets. The research method applied is illustrative case study, the aim of which is to show how important knowledge management is for improving the efficiency of an internationalized enterprise.
Moisture sorption is one of the most important destruction factors for colloidal capillary-porous exhibits in museums (painting, clothing etc.), which is dependent on microclimate in museum rooms. The analysis of moisture sorption properties, kinetics of sorption and swelling of textile museum exhibits is carried out. Isotherms of desorption of viscose and woollen yarns and fabrics of different density (and threads of them) are identical. The analysis of the isotherms of fabrics of various fibre cloths and threads of them shows that they all are similar in shape to the curves and have the form typical for leading capillary-porous bodies. The hysteresis loop for almost all tissues is observed throughout the range of relative humidity of the medium. In this work, the characteristics of the hysteresis loop (area, limited by it, length of the loop), which are of informational significance in the description of the processes of isothermal sorption-desorption of the materials mentioned above, are indicated. The research results allow optimizing of microclimate control in museum rooms for elimination of destruction of exhibits, improve the safety of storage and ensure the hygiene of the air indoor environmental.
