BACKGROUND There are several numerical investigations on bone remodelling after total hip arthroplasty (THA) on the basis of the finite element analysis (FEA). For such computations certain boundary conditions have to be defined. The authors chose a maximum of three static load situations, usually taken from the gait cycle because this is the most frequent dynamic activity of a patient after TH...

Bridge management officials have expressed a keen interest in the use of low-cost and easy-to-install wireless sensors to record bridge responses during short-term load testing. To illustrate the suitability of wireless sensors for short-term monitoring of highway bridges, a wireless monitoring system is installed upon the Grove Street Bridge to monitor structural responses during static and dy...

A fundamental issue affecting the performance of a parallel application running on message-passing parallel systems is the assignment of tasks to processors in order to get the minimum completion time. In SEPP and HPCTI, tools for static and dynamic task assignment are considered complementary: static mapping tools compute and initial assignment of tasks on processors while dynamic load balanci...

axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. in spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

Measurement of static electricity is of critical importance in assessing the proper electric properties of car seat covers and their suitability to be used in application to enhance the safety and stability of the driver. The present work aims to measure the static electric charge generated from the contact and separation of materials used as car seat covers and clothes. Different materials of ...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

Scalability becomes the basic need for distributed systems. With the increase of users, load on application servers also keep increasing. This requires a critical action to balance the load on servers. Load balancing is the concept of balancing load on servers using various load balancing techniques. In this paper we discuss various load-balancing techniques that are currently available. We dis...

As for a variable air volume (VAV) system, the air duct static pressure is a typical control variable maintained by modulating supply fan speed. The static pressure equals to the summation of the duct pressure loss downstream of the sensor to the terminal box and box inlet static pressure. Typically, the air duct static pressure is set as a constant set point based on the system design informat...

Computational grid nowadays has become a hotspot in high performance computing environments because it can solve larger scale computing problems. The present load balance strategy in computing grid such as the Globus tools is static. This paper mainly focuses on dynamic load balance in the computational grid. We put forward a new model that solves the dynamic load balance problems on computatio...
