We present a novel method to achieve light trapping in thin film silicon solar cells. Unlike the commonly used surface textures, such as Asahi U-type TCO, that rely on light scattering phenomena, we employ embossed periodically arranged micro-pyramidal structures with feature sizes much larger than the …

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 …

Laboratory research was done on flat glass substrates to study the effect that brine salinity has on adhesion mechanisms between oil and clay particles. This is done by evaporating a small clay suspension droplet (6 ul) on a glass slide that leaves a thin layer of clay upon which oil can be attached. …

Validation of a new method for ultrasonic structural health monitoring using advanced signal analysis. This paper presents the results of research on a new method for the monitoring of structural health using ultrasound. Conventional ultrasonic methods use the damping of the first arrival of the echo …

In dit artikel past Bain de principes van „How People Learn‟ toe in het geschiedenisonderwijs. Het boek „How People Learn‟, voor het eerst uitgegeven in 1999, is het resultaat van een onderzoek naar de stand van zaken op het gebied van leren en onderwijzen in de Verenigde Staten door wetenschappers uit …

BACKGROUND: Although many patients with foot complaints receive customized insoles, the choice for an insole design can vary largely among foot experts. To investigate the variety of insole designs used in daily practice, the insole design and its effect on plantar pressure distribution were investigated …

Where does entrepreneurship start? Moreover, what is so different about entrepreneurship in this New Age of innovation? What do entrepreneurs do when the world becomes more ‘flat’? According to The Entrepreneurial Society by David Audretsch something novel is happening, something only Schumpeter (1942) …

In dit afstudeeronderzoek is de volgende onderzoeksvraag onderzocht: "Wat is de behoefte van ACT- cliënten op het gebied van het sociale netwerk?" Dit afstudeeronderzoek is in opdracht van GGNet in Apeldoorn. De onderzoeksvraag is ontstaan vanuit het ACT- team van GGNet. De onderzoekers hebben geprobeerd …

Introduction: To reduce continuously increasing costs in drug development, adverse effects of drugs need to be detected as early as possible in the process. In recent years, compound-induced gene expression profiling methodologies have been developed to assess compound toxicity, including Gene Ontology …

Voor ons afstudeerproject hebben we uitgezocht welk systeem de beste keus is wanneer een nieuw angiostatief zou moeten worden aangeschaft. Er zijn namelijk twee keuzes. De al langer bestaande beeldversterker-TV keten en de, recent geïntroduceerde, flat-panel detector. Voordat we begonnen aan onze proeven …
