One of the major problems in Optical Burst Switching (OBS) networks is burst contention. Deflection routing is used to resolve the contention problem. Burst Loss ratio (BLR) is the ratio of the lost bursts to the total sent bursts from the transmitter to the receiver. Burst retransmission is used to reduce the BLR by retransmitting dropped bursts. Previous research papers show that combining de...

When the tip of a hair bundle is deflected by a sensory stimulus, the stereocilia pivot as a unit, producing a shearing displacement between adjacent tips. It is not clear how stereocilia can stick together laterally but still shear. We used dissociated hair cells from the bullfrog saccule and high-speed video imaging to characterize this sliding adhesion. Movement of individual stereocilia was...

Considering backlash, time-varying mesh stiffness and radial clearance of bearing, nonlinear dynamic model of gear bearing flexible shaft system is established taking into account breathing crack in shaft and tooth wear. Nonlinear dynamic equations are solved by Runge-Kutta method. Effect of backlash, crack in shaft and tooth wear faults on the nonlinear dynamic behavior of gear-shaft-bearing s...

This paper describes a novel measurement method to accurately measure the rotating shaft tilt angle of rotating machine for alignment or compensation using a dual-axis inclinometer. A model of the rotating shaft tilt angle measurement is established using a dual-axis inclinometer based on the designed mechanical structure, and the calculation equation between the rotating shaft tilt angle and t...

BACKGROUND Femoral stress fractures tend to occur at the neck, medial proximal-shaft, and distal-shaft. The purpose of this study was to determine the internal femoral forces and moments during running. It was expected that larger loads would occur at these common sites of femoral stress fracture. METHODS Ten subjects ran at their preferred running speed over a force platform while motion cap...

A Multivariable Control System is designed for an Electromagnetic Bearing and Rotating Shaft System. The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) methodology is used to design a robust Model Based Compensator (MBC). The electromagnetic bearing consists of an electromagnetic actuator, operated in magnetic "attractive" force mode, with permanent magnet biased coils. The per...

Employing an atomic force microscope (AFM) in conjunction with a quartz crystal microbalance, we have investigated how a high-frequency lateral oscillation of the substrate influences the imaging process of the AFM. It was found that the time-averaged deflection of the cantilever (both vertical and lateral) changed when the oscillation of the quartz resonator was turned on. The vertical-tip-sub...

Automotive drive Shaft is a very important components of vehicle. The present paper focuses on the design of such an automotive drive shat by composite materials. Now a days two pieces steel shaft are used as drive shaft. However, the main advantages of the present design is; only one piece of composite drive shat is possible that fulfil all the requirements of drive shaft. Two different design...

This paper presents a novel real-time crack identification method to determine the position and depth of a transverse open crack on a rotating shaft. A newly developed wireless sensor capable of being mounted directly on the shaft can be employed to monitor acceleration at different points of a shaft in a rotating coordinate system. The vibration parameters obtained from a Finite Element Model ...

In this study, Gene Expression Programming (GEP) is used in modeling the deflection basins measured on the surface of the flexible pavements. Backcalculation of the pavement layer moduli are well-accepted procedures for the evaluation of the structural capacity of pavements. The ultimate aim of the backcalculation process from Nondestructive Testing (NDT) results is to estimate the pavement mat...
