The bridge of Shanghai Metro Line 10 over 6 is a U-shaped concrete single-box double-cell box beam continuous bridge. A novel method applied to construct the asymmetric cantilever prefabricated and assembled due limited construction space complex environment. Four mechanical state control methods are during T-shape structure process: tensioning pre-stressed steel strand, jacking by axial force ...

Natural and artificial superhydrophobic surfaces are a rapidly growing topic in both academia industry due to their unique properties applications. Numerous techniques have been developed characterize the wetting of such surfaces, as optical contact angle goniometer, force-based methods, microscopic for visualizing interface. However, method that combines nN resolution force measurement with di...

Cantilevers fabricated by means of micromachining techniques are usually used for atomic force microscopy. In this paper, the spring constant of an atomic force microscope (AFM) cantilever is determined by using a large-scale cantilever. Since the spring constant of the large-scale cantilever is calibrated accurately, the spring constant of the AFM cantilever is determined precisely by measurin...

The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

Although dental implants have been successfully used for the rehabilitation of fully edentulous and partially edentulous patients, patient’s various conditions constrict the application of implant, or make dental treatment using dental implants very complex and difficult. Implantsupported cantilever prostheses represent that conditions. Becker and Kaiser insisted that alignment problems, extens...

This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...

Due to their small size, low weight, low cost and low energy consumption, MEMS (Micro Electro-Mechanical Systems) accelerometers have achieved great commercial success in recent decades. The objective of this paper is to find the optimum design for a typical MEMS accelerometer, which satisfies a set of given constraints. Due to the complex nature of the problem, a gravitational search algorithm...
