Friction is the result of complex interactions between contacting surfaces in a nanoscale perspective. Depending on the application, the di erent models available are more or less suitable. Available static friction models are typically considered to be dependent only on relative speed of interacting surfaces. However, it is known that friction can be a ected by other factors than speed. In thi...

Flexible barriers undergo large deformation to extend the impact duration, and thereby reduce the impact load of geophysical flows. The performance of flexible barriers remains a crucial challenge because there currently lacks a comprehensive criterion for estimating impact load. In this study, a series of centrifuge tests were carried out to investigate different geophysical flow types impacti...

In this paper we propose a new scheduling policy namely IRD (Intelligence Request Dispatcher) for web switches operating at layer-7 of OSI protocol stack in a web server farm .we classify dynamic and static requests. A hybrid Neuro-Fuzzy and LARD like approach is used to make route decision of dynamic and static requests separately. IRD select server with lower response time in an adaptive disp...

This study presents a steel container crane movement analysis and assessment based on structural health monitoring (SHM). The accelerometers are used to monitor the dynamic crane behavior and a 3-D finite element model (FEM) was designed to express the static displacement of the crane under the different load cases. The multi-input single-output nonlinear autoregressive neural network with exte...

Cloud computing provides on-demand hosted computing resources and services over the Internet on a pay-per-use basis. It is currently becoming the favored method of communication and computation over scalable networks due to numerous attractive attributes such as high availability, scalability, fault tolerance, simplicity of management and low cost of ownership. Due to the huge demand of cloud c...

During the last decade power system have been equipped with complex components such as Distribution Static Var Compensators (D-SVCs). These components have introduced new possibilities to control power systems, D-SVCs can almost continuously change the amount of reactive power from capacitor banks. The behavior of these new components is different from 'old' technologies since they contain powe...

Abstract—In this paper, the results of experimental tests performed on a Helical Wire Rope Isolator (HWRI) are presented in order to describe the dynamic and static behavior of the selected metal device in three different displacements ranges, namely small, relatively large, and large displacements ranges, without and under the effect of a vertical load. A testing machine, allowing to apply hor...

Occupations requiring frequent periods of static lumbar flexion are known epidemiologically to be risk factors for the development of cumulative low back disorder. The impact of the load magnitude sustained during a series of short static lumbar flexions followed by an equally long rest period on the development of a cumulative low back disorder was addressed in an in vivo feline model. Static ...

In order to evaluate the mechanical condition and working performance of a rigid frame bridge after reconstruction extension, was analyzed by static load test. Static test is stress at each section main beam under action partial medium load. The results show that, load, check coefficient strain deflection measuring point box girder does not exceed standard limit value 1, relative residual or de...

A small-scale biomechanical disc culture system was designed to stimulate intervertebral disc (IVD) 'motion segment' in culture environment with load-controlled compression and combined load (compression+shear). After 7 days of diurnal mechanical loading, cell viability of discs stimulated with static compression load (0.25 MPa) and static combined load (compression (0.25 MPa)+shear (1.5N)) wer...
