Seit über 50 Jahren beschäftigt sich die Wissenschaft ernsthaft mit dem Thema ”Stau”. Ob Fahrzeuge, Menschen, Tiere oder Mikroben, überall wo sich viele ähnliche Objekte zur selben Zeit am selben Ort in dieselbe Richtung bewegen wollen, tritt er auf. Oft ohne erkennbaren Grund und plötzlich (”Stau aus dem Nichts”). In der Zwischenzeit sind manche Rätsel geklärt, einiges aber bleibt auch weiterh...

Considerable eeorts have been undertaken to construct environments supporting dynamic software processes. The road to success neither takes us into the runtime stack of the process engine (rule-based approaches), nor may we tolerate the straight-jacket of a static Petri net. We propose an environment centered around dynamic task nets, which provide project managers with all details required to ...

The paper introduces three patterns for use by university managers and lecturers for creating of Master of Science (MSc) program in engineering and science faculties, developing entrepreneurial skills: TECHNOLOGY ENTREPRENEURSHIP AND INNOVATION (TEI) CURRICULA – provide a valuable and computational set of courses to guarantee the competence of graduate students in the turbulent environment; TEI...

The research asked whether Mobile GIS that incorporated speech recognition was a viable tool for locating defects in pavement, curbs and footpaths. A Xybernaut MA IV wearable computer and Dragon NaturallySpeaking’s speech recognition software were tested, and the Geography Markup Language, GML 2.0, was used to implement an application schema for street condition surveys. Both technical and over...

Annually, more than 1 million people were killed in road traffic accidents worldwide every year and an uncounted number were severe injured. In 2012 fatal injuries caused by road traffic accidents are under the top ten lists of causes of death in the world. It´s expected that in the near future road traffic accidents become one of the main causes of death in the world. Most of these fatal injur...

information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of caspian forests. skidding and road construction costs are expensive forest operations. determining the optimum forest road network density is one of the most important factors in sustainable forest management. logging me...

When data are limited it is difficult for conservation managers to assess alternative management scenarios and make decisions. The natterjack toad (Bufo calamita) is declining at the edges of its distribution range in Europe and little is known about its current distribution and abundance in Poland. Although different landscape management plans for central Poland exist, it is unclear to what ex...

Thousands of mammals are killed annually from vehicle collisions, making the issue an important one for conservation biologists and environmental managers. We recorded all readily identifiable kills on or immediately adjacent to roads in the southern Great Plains from March 2004-March 2007. We also recorded distance traveled, whether a road was paved or divided, the number of lanes, and prevail...

Effects of fragmentation on the ecology of organisms occupying dendritic ecological networks (DENs) have recently been described through both conceptual and mathematical models, but few hypotheses have been tested in complex, real-world ecosystems. Stream fishes provide a model system for assessing effects of fragmentation on the structure of communities occurring within DENs, including how fra...
