Prognozowanie wskaźnika motoryzacji na poziomie województw
PublikacjaWskaźnik motoryzacji jest jedną z najczęściej używanych, unormowanych miar rozwoju motoryzacji. W wielu krajach opracowano i wykorzystuje się krajowe i regionalne modele rozwoju motoryzacji. W Polsce szczegółowe badania nad czynnikami rozwoju motoryzacji dotychczas nie były prowadzone. Autorzy artykułu podjęli wyzwanie uzupełnienia tej luki i opracowali metodę prognozowania liczby pojazdów jako miary ogólnej i wskaźnika motoryzacji...

Comparison of Surface Quality and Tool-Life of Glulam Window Elements after Planing
PublikacjaThe quality of the surface of wooden elements, that have been planed, has a crucial importance in the whole production process, since the obtained effects affect the quality of wooden surface after fi nishing (painting). The occurrence of defects is usually the reason for qualifying a workpiece as scrap or for requiring additional work. This paper presents the selected results of research of the effect of the cutting tool wear...

The methodology for determining of the value of cutting power for cross cutting on optimizing sawing machine
PublikacjaIn the article the methodology of forecasting the energy effects of the cross-cutting process using the classical method, which takes into account the specific cutting resistance, is presented. The values of cutting power for the cross-cutting process of two types of wood (softwood and hardwood) were forecasted for the optimizing sawing machine with using presented methodology. The cross-cutting process with high values of feed...

Assessment of Road Restraint Systems in Polish Conditions
PublikacjaKey to understanding the needs and tools of road infrastructure management is identifying the hazards and their sources involved in having no or faulty road restraint systems. Clarity is also needed on why the systems are wrongly designed, constructed, built and operated. To ensure that the problem is adequately understood, research and site observations were conducted and...

Impact of adverse winter weather on traffic flow
PublikacjaThe paper aims to analyse the impact of adverse weather in winter on traffic flow using data from a dual carriageway section of an express road located in Gdansk. For the purposes of the analysis, traffic and meteorological data were collected for a period of 15 months in 2014-2015 and aggregated to 5 minutes intervals. The impact of winter weather conditions on traffic flow was assessed by comparing aggregated traffic stream parameters...

The effect of road restraint systems on the level of road safety - Polish experience
PublikacjaRoadside accidents happen when a vehicle runs off the road. The majority of these accidents are very severe because leaving the road is usually followed by hitting a solid obstacle (tree, pole, support, culvert front wall, barrier). Roadsides are some of the most important issues of road safety. They have been studied for years to identify roadside hazards and the effectiveness of road safety measures such as restraint systems....

The effect of full-cell impregnation of pine wood (Pinus Sylvestris L.) on the fine dust content during sawing on a frame sawing machine
PublikacjaIn this paper the results of the analysis of the effect of the impregnation treatment of pine wood on the granularity of sawdust from the sawing process on the frame sawing machine PRW 15M are presented. Granulometric analyses of chips from impregnated and unimpregnated pine wood implies that the impregnation of pine wood does not affect the size and structure of the sawdust produced. A major ≈ 95% share of the formed chips is...

Analysis of the impact of socio-economic development on road safety based on the example of Baltic Sea Region countries
PublikacjaBaltic Sea Region (BSR) is a specific region of Europe, bringing together countries with different levels of socio-economic development. The main common point is territorial access to the Baltic Sea and the importance of maritime transport in the transportation of goods. The region consists of 9 countries, including Germany, Poland, Lithuania, Latvia, Estonia, Finland, Sweden, Denmark and Russia (more specifically, Kaliningrad...

The forming and emission of high power electromagnetic pulses
PublikacjaAn impulse energy source, a power conditioning system and an electromagnetic field emitter are essential to generate an electromagnetic field pulse (EMFP) with a specific frequency bandwidth. Selected simulation results for a power conditioning system consisting of a fuse opening switch and a paraboloidal electromagnetic emitter have been presented in this article. The synthetic system examined in the simulation is powered by an...

Analiza właściwości emiterów impulsowych pola elektromagnetycznego
PublikacjaW pracy przedstawiono analizę porównawczą wybranych emiterów pola elektromagnetycznego w oparciu o badania symulacyjne. Badane emitery różnią się kształtem i rozmiarem elementów składowych. Analiza dotyczy właściwości impulsów pola elektromagnetycznego. Porównano właściwości kierunkowe, efektywności emisji oraz częstotliwości własne emiterów. Wskazano na najbardziej korzystną z punktu widzenia tych parametrów konstrukcje emitera.

Zastosowanie wyłącznika bezpiecznikowego do formowania impulsu wielkiej mocy
PublikacjaW wielu układach fizycznych i technicznych konieczne jest wytwarzanie impulsów wielkiej mocy o krótkim czasie trwania (rzędu ułamków µs). Impulsy te uzyskuje się stosując układy formujące zasilane ze źródła impulsowego wielkiej mocy, o długim czasie trwania impulsu, rzędu kilkudziesięciu µs. Jednym z układów formujących jest bezpiecznik wyłącznikowy. W pracy metodą symulacyjną badano wpływ parametrów bezpiecznika wyłącznikowego...

Road safety inspection as a tool for road safety management – the polish experience
PublikacjaIn Poland, road inspections were implemented in June 2014 on all national roads. Previously conducted traffic surveys mainly related to the technical condition of roads, signs and markings; other safety issues were overlooked. The main problem that occurs during inspection is an inspector’s subjective qualitative assessment which affects the classification of the sources of hazard on the road.. The paper presents an analysis of...

Effect of the Road Environment on Road Safety in Poland
PublikacjaRun-off-road accidents tend to be very severe because when a vehicle leaves the road, it will often crash into a solid obstacle (tree, pole, supports, front wall of a culvert, barrier). A statistical analysis of the data shows that Poland's main roadside hazard is trees and the severity of vehicles striking a tree in a run-off-road crash. The risks are particularly high in north-west Poland with many of the roads lined up with...

Development of dynamic method for evaluation of inhibition efficiency on the example of 8-hydroxyquinolin
PublikacjaSelection of a proper inhibitor should be based on the evaluation of its mechanism and effective concentrations. Mechanism of inhibition usually has dynamic character due to changing physicochemical conditions of the environment and corroding metal surface. Most of actually used methods are stationary or contain assumptions which highly influences obtained values. Development of new dynamic method, based on modified EIS, allows...

Assessment of organic coating degradation via local impedance imaging
PublikacjaThe paper presents a new approach to organic coating condition evaluation at micrometer scale using localized impedance measurements. It is based on atomic force microscopy (AFM) in contact mode. Impedance is measured between conductive AFM tip and metal substrate covered with organic coating. A single-frequency voltage perturbation signal is applied between the electrodes and current response signal is registered. As the tip is...
