International entrepreneurship is an important vehicle for firms to reap benefits from their high productivity levels and from economies of scale by reaching new customers. International enterprises tend to be larger and more innovative, but a key question of causality remains disputed in the international …

Path tracking driver models assume the observed path deviation ahead of the vehicle to be proportionally transferred to a corrective steering input. The most simple version of such a model includes three parameters, a single preview distance, a steering gain and a delay time, being examined in this paper, …

An existing fuel cell hybrid distribution truck, built for demonstration purposes, is used as a case study to investigate the effect of stack (kW) and battery (kW, kWh) sizes on the hydrogen consumption of the vehicle. Three driving cycles, the NEDC for Low Power vehicles, CSC and JE05 cycle, define …

One way to reduce the fuel consumption to payload ratio of heavy vehicle combinations is to reduce the empty trailer weight. This requires an understanding of the vehicle structure, assembly techniques and production process, and of special materials (e.g. high strength steel) with emphasis on strength …

The paper discusses the derivation of test data for three tractor-semitrailer combinations, to be used for strength and durability analysis of semi-trailers with the ultimate goal to reduce the semitrailer mass. Mathematical relationships have been used to transfer these data to representative loading …

Veel ruimtelijke vraagstukken, zoals volkshuisvesting en wateropslag, worden steeds vaker op regionaal niveau aangepakt. Planning en beleidsontwikkeling nemen echter veel tijd in beslag. Dit komt deels door gebrek aan ervaring, maar ook door het toenemend aantal partijen waarmee rekening moet worden …

At HAN University research has been started into the development of a PEM fuel cell hybrid power train to be used in an automated guided vehicle. For this purpose a test facility is used with the possibility to test all important functional aspects of a PEM fuel cell hybrid power train. In this paper …

Optimization routines for battery, supercap and fuel cell stack in a fuel cell based propulsion system face two problems: the tendency to cycle beating and the necessity to maintain identical amounts of stored energy in battery and supercap at the start and end of the driving cycle used in the simulation. …

Society and (higher) education have changed rapidly in recent decades. For example, since knowledge has become more volatile, life-long learning has become increasingly important. Higher education itself has been subject of change in the last decade as well. Particularly in the wake of social-constructivist …
