The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

The issue of management of the supply chains of electronics in a sustainable manner is becoming more and more important all around the world. There are growing concerns about the amounts of electronic waste, controversial labour practices and the chemical and energy consumption management. These are …

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 …

A new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …

Model calculations and the few data that are available show that over 100 L water condense yearly on each square meter of a greenhouse cover. It is known that the presence of condensate reduces light transmission. This effect is suppressed to some extent by adding film-forming (anti-drop) additives to …

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 …

The scope of this investigation is the development and testing of a new type of greenhouse with an integrated linear Fresnel lens, receiver module and an innovative system for tracking to exploiting all direct radiation in a solar energy system. …

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 …

In an previous research project a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed which has an integrated filter for reflecting the near infrared radiation (NIR) to the greenhouse and exploiting this radiation in a solar energy system. The performance of …

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 …
