In recent years, the Q-factor of [Formula: see text] nanomechanical resonators has significantly been increased by soft-clamping techniques using large and complex support structures. To date, however, obtaining similar performance with smaller supports remained a challenge. Here, we make use torsion beam to tune string resonators. By design optimization supports, obtain 50% enhancement compare...

A resonance based micro pressure sensor is designed and simulated an analytical overview of its working presented. The resonator used electrostatically actuated clamped-clamped (cc) beam supported over docks. correlation between stress in micro-resonator width docs the support structure evaluated. It compared to a without it found that with provides better sensitivity. Performance device evalua...

in order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. the shore power supply which needs transferring 380v/50hz to 450v/60hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...

This paper reports on the fabrication and characterization of high-quality factor (Q) single crystal silicon (SCS) in-plane capacitive beam resonators with sub-100 nm to submicron transduction gaps using the HARPSS process. The resonating element is made of single crystal silicon while the drive and sense electrodes are made of trench-refilled polysilicon, yielding an allsilicon capacitive micr...

A Bäcklund transformation(BT) and a recurrence formula are derived by the homogeneous balance(HB) method. A initial problem of Burgers equations is reduced to a initial problem of heat equation by the BT, the initial problem of heat equation is resolved by the Fourier transformation method, substituting various solutions of the initial problem of the heat equation will yield solutions of the in...

Discrete waves in the voltage-clamped photoreceptor of Limulus are remarkably similar in all essential properties to those found in an unclamped cell. The latency distribution of discrete waves is not affected by considerable changes in the holding potential in a voltage-clamped cell. Both large and small waves occur in voltage-clamped and unclamped cells and in approximately the same proportio...

This study presents the effect of vertical and horizontal oriented cracks on free vibration response for circular annular thin plates. To investigate dynamic behavior damaged structures are modeled separately considering horizontal/vertical orientations, ten different locations, four crack sizes. For plates, placed in middle between outer inner edges to directions. The first five resonant frequ...

In this paper, the 14-equations of pipeline system were written as matrix forms in frequency domain with Laplace transformation and further solved by transfer method (TMM). Moreover, added mass damping models established combined TMM for decoupling investigated Turbulence-Induced Vibration (TIV) clamped-clamped pipe system. Firstly, feasibility analyzing responses water-filled pipelines free su...

This study aims to investigate the elastic–plastic response of a clamped-clamped beam struck by rigid heavy mass with low velocity at any point on span. The impact system is simplified as single-degree-of-freedom (SDoF) mass-spring model formulate beam’s equations motion during loading and unloading. With consideration material elasticity large deflection, analytical solutions are derived predi...
