We study the macroscopic profiles of temperature and angular momentum in stationary state chains rotors under a thermo-mechanical forcing applied at boundaries. These are solutions system diffusive partial differential equations with boundary conditions determined by forcing. Instead expensive Monte Carlo simulations underlying microscopic dynamics, we perform extensive numerical computations b...

OBJECTIVES The purpose of present study was to evaluate the internal adaptation of composite restorations using different adhesive systems. MATERIALS AND METHODS Typical class I cavities were prepared in 32 human third molars. The teeth were divided into the following four groups: 3-step etch-and-rinse, 2-step etch-and-rinse, 2-step self-etch and 1-step self-etch system were used. After the d...

fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). it is well known that the structure and prope...

This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibra...

The Department of Mechanical Engineering is one of four departments within the Thomas J. Watson School of Engineering and Applied Science at the State University of New York (SUNY) at Binghamton. The undergraduate educational experience emphasizes the application of a wide spectrum of engineering fundamentals. Care has been taken to ensure a balanced integration of theory, design and laboratory...

S. Krum, F. Pešlová, Czech Technical University in Prague, Faculty of Mechanical Engineering Prague, Czech Republic, J. Kliber VŠB TU Ostrava, Czech Republic Corrosion resistant steels are used for the prod uction of parts exposed to corrosive environment and also to thermo-mechanical loads. Steel molds in the glass manufacture industry with their functional surfaces simultaneously exposed to t...

Highly environmentally-friendly fibreboards were manufactured by hot-press moulding using Posidonia ocaeanica wastes and a partially biobased epoxy resin as binder. Fibreboards with a constant fibre content of 70 wt % were successfully manufactured by thermo-compression. The effects of a conventional alkali treatment were compared to the synergistic effects that additional silanization with two...

Temperature and thermal stress responses of an improved TTSV structure under the impact of hotspots are numerically analyzed in this paper. A Fin structure is added to the circular TTSV to strengthen the effect of thermo-mechanical mitigation. The nonlinear finite element method (N-FEM) is presented to obtain the coupled thermal and mechanical fields. Running time of the N-FEM algorithm is comp...
