A promising method for low cost production of efficient silicon thin film solar cells is the electron beam physical vapor deposition (EB-PVD) of high purity amorphous silicon (a-Si) layers with high deposition rates up to 300 nm/s [1] followed by crystallization. This study focuses on EB ... Per saperne di più
At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), ...

At present, a great deal of research effort has been directed to find eco-friendly and renewable sources of energy. With the rising costs of crude oil and petroleum, along with the derogatory effects that they pose to the environment, this sort of approach is of utmost importance. This ... Per saperne di più
In the paper we examine the accuracy of various meshes for different model regions and simple differential equations in 2D and in 3D. We study the potential equation for a single irregular domain (2D testcase 1), for a simple domain with irregular sub-domains (2D testcase 2) and a 3D ... Per saperne di più
INTRODUCTION: Active cooling systems represent a possible solution to the electronics overheating that occurs in downhole tools operating on wireline, a cabling technology used to remotely control the downhole devices during oil and gas well interventions, in high temperature wells (150 ...
