Fuel cell hybrid vehicles are believed to provide a solution to cut down emissions in the long term. They provide local zero-emission propulsion and when the hydrogen as fuel is derived from renewable energy sources, fuel cell hybrids enable well-to-wheel zero-emission transportation, …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

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 …

Fuel cell hybrid power trains comprise an energy storage to supply peaks in the power demand and to facilitate regenerative braking. In terms of control systems, the presence of storage provides additional freedom to minimize the vehicle’s fuel consumption. In a previous paper [1] an analytical solution …

News media in The Netherlands show great variety in the extent and ways, in which they realize media accountability online in terms of actor transparency, product transparency and feedback opportunities online. It is suggested that even those news rooms that seem to adhere to transparency and public …

The airline industry is a subject that is often reported in the media these days. Especially in the last years, a lot of mergers and accessions to alliance have taken place. What is more, a strong competition of low-cost carriers is going on in which cheaper fares are offered with less service on board. …

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 …

This paper focuses on the concept climate refugees in the 21st Century and mainly concerns environmentally displaced persons from developing countries. It seeks to answer the following question: 'Should the concept of climate refugees best be approached from a juridical or an environmental point of view?' …
