Storing large amounts of data in an efficient way from the point of view of very fast retrieval is animportant requirement for many industries like KEMA, a company offering consulting, testing andcertification in the energy business. Because their relational database could not cope fast enough with thelarge …

Nederland beschikt over 350 serviceflats, met opgeteld circa 40.000 appartementen5). Ooit vormden ze een breed gewaardeerd alternatief voor wonen in een verzorgingshuis. Op dit ogenblik worden nogal wat complexen met leegstand geconfronteerd. Dat is opmerkelijk: enerzijds neemt het aantal ouderen als …

De lectoraten Wijkzorg (Hogeschool Rotterdam) en Langdurige Zorg (Hogeschool van Arnhem en Nijmegen) deden begin 2012 onderzoek naar het opleidingsaanbod voor wijkverpleging op de Nederlandse opleidingen hbo-v. De meest in het oog springende conclusie: het vak wijkverpleging is niet herkenbaar in het …

To increase knowledge on haem biosynthesis in filamentous fungi like Aspergillus niger, pathway-specific gene expression in response to haem and haem intermediates was analysed. This analysis showed that iron, 5-aminolevulinic acid (ALA) and possibly haem control haem biosynthesis mostly via modulating …

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 …

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, …

In this paper we discuss the use and challenges of identifying communities with shared semantics in Enterprise Modeling. People tend to understand modeling meta-concepts (i.e., a modeling language’s constructs or types) in a certain way and can be grouped by this understanding. Having an insight into …

In this paper we explore the subject of question asking as an inherent driver of enterprise modelling sessions, within the narrower context of the ‘dialogue game’ approach to collaborative modelling. We explain the context, but mostly report on matters directly concerning question asking and answer pre-structuring …

In this study, we present a new light absorption enhancement method for p-i-n thin film silicon solar cells using pyramidal surface structures, larger than the wavelength of visible light. Calculations show a maximum possible current enhancement of 45% compared with cells on a flat substrate. We deposited …
