THE INFLUENCE OF HOUSING ARRANGEMENT AND INTERFERENCE ON PRELOAD AND THEORETICAL LIFETIME OF A SYSTEM OF TAPER ROLLER BEARINGS OF A HIGH SPEED SHAFT OF A WIND TURBINE GEARBOX
PublikacjaA system of two taper roller bearings can carry loads with a high ratio of axial load to radial load. Such a system was proposed for a wind turbine gearbox following the poor durability of original bearing design with the aim of increasing durability. Because of size limits, a proposed system is composed of two different taper roller bearings. Standard manufacturers’ catalogues do not provide information on recommended preload...

Otoczenie mikroprzedsiębiorstw w opiniach ich właścicieli
PublikacjaRola postrzegania przez właściciela otoczenia własnej firmy, jak i sytuacji w samej firmie jest istotna w kontekście planowania przyszłości firmy. Otoczenie firmy odgrywa istotną rolę w procesie jej rozwoju. Jednak właściciele mikro i małych przedsiębiorstw nie są wystarczająco kompetentni by prawidłowo ocenić sytuację ekonomiczną. Dlatego też ich ocena dotycząca otoczenia jest w dużym stopniu subiektywna. Na przełomie 2012/2013...

Architekt miasta wczoraj i dziś - wizjoner czy administrator? Uwagi na temat roli architekta miejskiego w kształtowaniu wizji miasta
PublikacjaArtykuł jest próbą oceny roli architekta miejskiego od początków XX wieku do czasów obecnych. Opracowanie bazuje na pytaniu badawczym, czy we współczesnym mieście wciąż jest miejsc na wizjonerską i wiodącą rolę architekta miejskiego w kształtowaniu przestrzeni, jak to miało miejsce w przeszłości. Architekci miejscy są dziś raczej związani z pełnieniem funkcji administracyjnych, natomiast kwestie przekształceń urbanistycznych powierzane...

Growth and characterization of PrBa2Cu3O7-δ single crystals
PublikacjaWe report on the growth of PrBa2Cu3O7-δ single crystals in the Al2O3 and ZrO2 crucibles by flux method. The high influence of the reaction between crucible and liquid on the initial melt composition has been established. We found that the precipitation of the chemically stable compound BaZrO3 and BaAl2O4 occurs by direct chemical reaction between BaCuO2 and ZrO2 or Al2O3 crucibles materials. Free separated crystals with maximum...

Direct human contact with siloxanes (silicones): safety or risk. Part 1: characteristics of siloxanes (silicones
PublikacjaSiloxanes are commonly known as silicones. They belong to the organosiliconcompounds and are exclusively obtained by synthesis. Their chemical structuredetermines a range of physicochemical properties which were recognized as unique.Due to the susceptibility to chemical modifications, ability to create short, long orcomplex polymer particles, siloxanes found an application in many areas of human life.

Saccharides
PublikacjaSaccharides are widely distributed in nature as the major component of fruits and vegetables (primarily monosaccharides), milk and malt (mainly disaccharides), and grains (mostly polysaccharides). They are an important source of energy, structural material, as well as flavor and taste factors. Molecules of this class of compounds contain mainly carbon, hydrogen, and oxygen atoms; however, most natural saccha- rides do not have...

Experimental Study of Polish Sausage Drying Kinetics and Contraction by Image Data Analysis
PublikacjaThe goal of this paper has been to add an experimental data set for drying a meat product and provide a comparison with well-established thin-layer drying models. This article presented experimental investigations on the convective drying of Polish sausage slices at a temperature of 40°C. Slices have been in the thickness of 3 to 8mm. Measurements of mass loss and size change were performed. The data have been presented in the...

Performance evaluation of the parallel object tracking algorithm employing the particle filter
PublikacjaAn algorithm based on particle filters is employed to track moving objects in video streams from fixed and non-fixed cameras. Particle weighting is based on color histograms computed in the iHLS color space. Particle computations are parallelized with CUDA framework. The algorithm was tested on various GPU devices: a desktop GPU card, a mobile chipset and two embedded GPU platforms. The processing speed depending on the number...

Comparison of single microjet cooling with water, ethanol and HFE7100 as test fluids
PublikacjaThe paper presents the investigation of a single microjet cooling forming an thin liquid film on the impingement surface of specially designed rig. The basis of microjet technology is to produce laminar jets, which when impinging the surface have a very high kinetic energy at the stagnation point. Applied technology of jet production can result with the size of jets ranging from 20 to 500μm in breadth and 20 to 100μm in width....

The Impact of Trade Integration with the European Union on Productivity in a Posttransition Economy: The Case of Polish Manufacturing Sectors
PublikacjaThis paper addresses the relationship between productivity growth in Polish manufacturing sectors and forces stemming from trade integration with the European Union. Empirical analysis (1995-2006) is based on sector-level bilateral data concerning both domestic (Polish) and foreign (partner countries from the enlarged European Union) markets' characteristics and their degree of openness. The main results indicate that, both in...

Global edge alliances in graphs
PublikacjaIn the paper we introduce and study a new problem of finding a minimum global edge alliance in a graph which is related to the global defensive alliance (Haynes et al., 2013; Hedetniemi, 2004) and the global defensive set (Lewoń et al., 2016). We proved the NP-completeness of the global edge alliance problem for subcubic graphs and we constructed polynomial time algorithms for trees. We found the exact values of the size of the...

Optimizing the computation of a parallel 3D finite difference algorithm for graphics processing units
PublikacjaThis paper explores the possibilities of using a graphics processing unit for complex 3D finite difference computation via MUSTA‐FORCE and WENO algorithms. We propose a novel algorithm based on the new properties of CUDA surface memory optimized for 2D spatial locality and compare it with 3D stencil computations carried out via shared memory, which is currently considered to be the best approach. A case study was performed for...
