STATEMENT OF PROBLEM Currently no data comparing the denture base adaptation of CAD-CAM and conventional denture processing techniques have been reported. PURPOSE The purpose of this in vitro study was to compare the denture base adaptation of pack and press, pour, injection, and CAD-CAM techniques for fabricating dentures to determine which process produces the most accurate and reproducible...

Abstract The establishment of perovskite solar cells (PSCs) in terms their power-conversion efficiency (PCE) over silicon-based is undeniable. state-of-art easy device fabrications PSCs has enabled them to rapidly gain a place third-generation photovoltaic technology. Numerous obstacles remain be addressed and stability. Low performance owing easily degraded surface deterioration film quality r...

Differential interference contrast is a potentially powerful technique for contrast enhancement in soft X-ray microscopy. We describe the design and fabrication of single-element diffractive optical elements suitable as objectives for high-resolution differential interference contrast microscopy in the water-window spectral range. A one-dimensional pattern calculation followed by an extension t...

Abstract: In this paper, we propose a temperature-aware DFS (Dynamic Frequency Scaling) technique using the performance counters that is already embedded in the commercial microprocessors. By using performance counters and simple regression analysis, we can predict the localized temperature and efficiently schedule the tasks considering the temperature. The proposed technique is especially bene...

In this paper, we report a simple technique for the fabrication of planar valveless micropumps. The technique utilizes MEMS fabrication methods by using a double sided etch technique. Instead of using several masks and process steps, an anisotropic wet etch technique at both sides of a silicon substrate is implemented at the same time for creating the pump membrane and the diffuser/ nozzle elem...
