Preconcentration of biomolecules by electrokinetic trapping at the nano/microfluidic interface has been extensively studied due to its significant efficiency. Conventionally, sample preconcentration takes place in continuous flow and therefore suffers from diffusion and dispersion. Encapsulation of the preconcentrated sample into isolated droplets offers a superior way to preserve the sample co...

Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...

A passive solar tracker and concentrator device must be able to effectively concentrate solar radiation into a constant area throughout the day, without any mobile mechanism. The objective is to achieve 1000 °C on the receptor area with concentrated solar energy, and to accomplish this target a compound Fresnel lens has been designed. Utilizing multidisciplinary CAE software, an integrated mult...

Measuring and charging heat consumption are not often worked out in the prevalent warm-water heating systems. The developed modern heat-meter device, which includes microcontroller, is self-calibrating and self-testing, it uses several correctional algorithms in order to increase accuracy after authentication. Consumption data and information about the work-state events are logged and stored by...

The characterisation of 85 rear-line-contacted silicon concentrator solar cells on one single wafer requires a fast, automated measurement system. In this paper an easy to use needle array measurement system is presented, which allows an automated sequential measurement of dark and light IV curves of all cells on one wafer. For acquiring IV curves under high illumination levels (up to 500 suns)...
