In this paper we discuss mixed-method research in HCI. We report on an empirical literature study of the NordiCHI 2012 proceedings which aimed to uncover and describe common mixed-method approaches, and to identify good practices for mixed-methods research in HCI. We present our results as mixed-method …

There are several greenhouses built with solar panels integrated into the roof. In summer time this will operate very well, although broad shadow stripes can result in growth and yield differences. In winter the amount of sunlight is further limited by the solar panels and will result in further reduction …

In psychiatric care professionals perceive some patients as ‘difficult’, especially patients with long-term non-psychotic disorders. For these patients few evidence-based treatments exist. An intervention program, Interpersonal Community Psychiatric Treatment (ICPT), was developed by the authors. It …

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, …

Tijdens de conferentie Trends in Welding Research van juni jl. in Chicago was een speciale sessie gewijd aan de microstructuurontwikkeling tijdens het lassen. Eén van de bijdragen was een presentatie van de onderzoeksresultaten van een M2i-onderzoek (Materials Innovation Institute), waarbij Tata Steel …

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, …

De voordelen van modelgebaseerde ontwikkeling van regelsystemen gelden voor het mkb net zo goed als voor grote bedrijven, maar de bijbehorende investeringen zijn lastiger te dragen door kleine en middelgrote bedrijven. De Han ontwikkelt daarom samen met een aantal mkb’ers een betaalbaarder ontwikkelplatform. …

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 …

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 …
