It is reported in the published literature that the resonant frequency of a silicon micromachined gyroscope decreases linearly with increasing temperature. However, when the axial force is considerable, the resonant frequency might increase as the temperature increases. The axial force is mainly induced by thermal stress due to the mismatch between the thermal expansion coefficients of the stru...
Recent interest in high-speed scanning probe microscopy for high-throughput applications including video-rate atomic force microscopy and probe-based nanofabrication has sparked attention on the development of high-bandwidth flexure-guided nanopositioning systems (nanopositioners). Such nanopositioners are designed to move samples with sub-nanometer resolution with positioning bandwidth in the ...
Background and study aims A 70-year-old-man underwent an esophagectomy and posterior mediastinal reconstruction for esophageal cancer that was curatively resected. Although the patient was allowed to eat after surgery, he repeatedly vomited after drinking water or eating meals and required continuous hospitalization. An upper gastrointestinal series and endoscopic examination revealed an obstr...
abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
Abstract The analyzed electrohydraulic servo valve is jet pipe type, is one of the mechatronics component used for precision flow control application. It consists of several precision and delicate components. For the analysis the jet pipe assembly of servovalve is identified and conducted a direct-solution steady-state dynamic analysis to study the response of the system for harmonic excitation...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
Although bamboo has been used structurally for millennia, there is currently increasing interest in the development of renewable and sustainable structural bamboo products (SBPs). These SBPs are analogous to wood products such as plywood, oriented strand board and glue-laminated wood. In this study, the properties of natural Moso bamboo (Phyllostachys pubescens) are investigated to further enab...
In the past, a beam constraint model (BCM) that captures pertinent geometric nonlinearities associated with large displacements has been proposed for slender spatial beams with uniform and symmetric cross-sections. By providing closedform parametric relations between the end-loads and enddisplacements of the beam, the BCM quantifies the constraint characteristics of the beam in terms of stiffne...
