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 …

Poland's veto against the Low Carbon Roadmap 2050 of 9 March 2012 represents the point of departure for this research. The aim was determine the extent to which the Council of Ministers retains veto powers on legislation pertaining to their national energy mix, or whether energy policy is governed by …

Background: Although the general assumption is that patients with rheumatoid arthritis (RA) have decreased levels of physical activity, no review has addressed whether this assumption is correct. Methods: Our objective was to systematically review the literature for physical activity levels and aerobic …

De opdracht achter dit project is het ontwerpen van een sampletransportsysteem voor FOM Rijnhuizen. De samples waar het om gaat zijn opgedampte spiegels, die extreem ultraviolet licht reflecteren. Het transport loopt van de Advanced Development Coater (ADC), waar de samples geproduceerd worden, naar …

Ymere and the city Almere will in the next ten years develop the residential area Almere Hout Noord. The ambitious targets of this area is a CO2 neutral and energy independent neighborhood with an EPC demand of 0,4. Because of the area's limitations an investigation into air source heat pumps was needed …

This research is done in order to create the best strategy for Philips Lighting in the changing markets of recently. The goal is to create opportunities while the European legislation concerning the incandescent light bulbs forces the company to gradually remove all its incandescent lamps. The legislation …

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 …

from the article: The demand for a wireless CO2 solution is ever increasing. One of the biggest problems with the majority of commercial available CO2 sensors is the high energy consumption which makes them unsuitable for battery operation. Possible candidates for CO2 sensing …

Throughout the world greenhouse horticulture is expanding and intensifying. The expansion is driven by the much higher production levels that are achieved in greenhouses compared to open fields. This provides increased income for farmers and a positive effect on rural development. Intensification is …

Introduction: It has been suggested that physical education (PE) can make a meaningful contribution to children's physical activity (PA) levels. The amount of moderate-to-vigorous physical activity (MVPA) in PE has been quantified in various manners, including heart rate monitoring and direct observation …
