ANALYSIS OF POSSIBILITIES FOR THE USE OF VOLUME-DELAY FUNCTIONS IN THE PLANNING MODULE OF THE TRISTAR SYSTEM
PublikacjaTravel time is a measure commonly used for traffic flow modelling and traffic control. It also helps to evaluate the quality of traffic control systems in urban areas. Traffic control systems that use traffic models to predict changes and disruptions in vehicle flows have to use vehicle speed-prediction models. Travel time estimation studies the effects of traffic volumes on a street section at an average speed. The TRISTAR Integrated...

Influence of service ageing on polyester-reinforced polyvinyl chloride-coated fabrics reported through mathematical material models
PublikacjaIn this paper the coupled service (constructional tension) and environmental (sunlight, rainfalls, temperature variations) ageing influence on the polyester-reinforced polyvinyl chloride (PVC)-coated fabric VALMEX is studied. Two cases of the same fabric have been analyzed: one USED for 20 years on the real construction of the Forest Opera in Sopot (Poland), and one kept as a spare material (NOT USED). The following tests have...

Determination of atmospheric pollutants in wet deposition
PublikacjaTransport wody z atmosfery do podłoża zachodzi głównie za pośrednictwem opadów atmosferycznych takich jak deszcz, mżawka, śnieg, grad i inne. Ich wspólną cechą jest znacząca prędkość opadania grawitacyjnego. Uzupełniającym sposobem depozycji zanieczyszczeń w fazie mokrej są osady atmosferyczne, które tworzą się bądź przez kondensację/sublimację pary wodnej pod wpływem radiacyjnego wychłodzenia podłoża (rosa,szron), bądź w wyniku...

„Space, architecture and infrastructure “in-between cities”.
PublikacjaThe article presents contemporary city problems, like division of the city, infrastructural barriers, empty spaces, chaotic development, cuting-off areas, threatening the city image and functioning. These problems can be best observed in the areas in-between cities. One of the main questions for urban planners and architects seems thus to be: how to connect the city spaces instead of creating the barriers, how to create the areas...

Impact resistance of plain and twill fabric in GFRP measured by active thermography
PublikacjaThis paper discusses the impact resistance of glass-fibre reinforced polymer (GFRP) composites depending on the type of reinforcement – plain or twill weave. The values of impact energy were: 3J, 10J and 15J. Specimens featuring twill weave transferred higher force during the impact as compared with plain weave specimens. It was observed that an increase of impact energy was accompanied by an increase of the disproportion in...

"Kaszuby". Obraz olejny
PublikacjaJednym z ulubionych tematów malarskich Kazimierza Ostrowskiego były jego ukochane Kaszuby. Pejzaż kaszubski ma w sobie szczególną surowość. Może to efekt kamienia, który stale wyłania się z uprawnych pól czy może szaro-cementowych zabudowań gospodarczych wyzutych z koloru i pozbawionych jakichkolwiek zdobień? Szczególnie odczuwam to wczesną wiosną, chwilę przed „wybuchem zieleni” a także jesienią wśród zapachu kartoflisk i porannej...
