Assessing the Effects of the Road Surface and Weather Conditions on Road Safety
PublicationWhen transport is analysed for its safe delivery the focus is mainly on assessing the safety of roads and the risk of undesired events. These include road accidents, an occurrence which is relatively rare and random. Randomness means that accidents depend on several factors which are partly deterministic (can be controlled) and partly stochastic (random and unpredictable). The set of crash contributing factors can be classified...

System of protection against electric shock for circuits with power electronics converters
PublicationModern low voltage circuits are very often equipped with power electronics converters, therefore in these circuits non-sinusoidal earth currents (touch currents) may occur. For non-sinusoidal currents safety criteria should be modified. This paper presents these modified criteria and a computer system of protection against electric shock which can be implemented in circuits with power electronics converters. The system is based...

Exploratory analysis - extraction of dispersed information
PublicationWiększość analityków środowiska uważa, że ich praca kończy sie z chwilą uzyskania wiarygodnych danych o zawartości w próbce poszukiwanego analitu. Jest to jednak przestarzały punkt widzenia. W typowej próbce środowiskowej oznacza się zwykle kilkanaście lub więcej analitów. ''Ręczna'' analiza wyników uzyskanych dla zestawu takich próbek jest praktycznie niemożliwa. Ponadto w takich wielowymiarowych danych najbardziej użyteczne informacje...

Proposed method for estimating the costs of safety barrier life cycle
PublicationToday barrier types are frequently selected for their price with little regard for the total costs the structure will incur over its lifetime. One of the basic tools designed to manage road infrastructure is the life cycle cost method (LCC, Life cycle cost). It sums up the costs to plan, design, build, operate (use and maintain) and decommission a road structure. Having developed dynamically at the turn of the century the method...

Extraction of information from born-digital PDF documents for reproducible research
PublicationBorn-digital PDF electronic documents might reasonably be expected to preserve useful data units of their source originals that suffice to produce executable papers for reproducible research. Unfortunately, developers of authoring tools may adopt arbitrary PDF generation strategies, producing a plethora of internal data representations. Such common information units as text paragraphs, tables, function graphs and flow diagrams,...
