To research the internal load transfer behavior and failure mechanism of a bird’s nest anchor cable anchoring structure based on pull-out test, bond-slip model is established basis statistical damage theory, distribution formula shear stress at anchorage agent–rock interface deduced. Combined with theoretical analysis, pulling out test particle flow code (PFC) numerical simulation as well axial...

The doubly-fed induction generator (DFIG) is widely used in variable speed wind energy conversion systems (WECS). This paper presents a review on various topologies, configuration, power converters and control schemes used with the operation of the DFIG. The operation of DFIG based on both slip ring and brushless arrangement has been discussed. The grid integration of DFIG and its influence on ...

This paper describes an experiment eliciting spoonerisms by using the so-called SLIP technique. The purpose of the experiment was to provide a further test of the hypothesis that self-monitoring of inner speech is a major source of lexical bias ([1; 10; 11; 14]. This is a follow-up on an earlier experiment in which subjects were explicitly prompted after each response to make a correction in ca...

In recent years, there has been considerable interest in investigating the effects of fretting, a common problem of significant practical importance that can affect a wide range of electrical equipment incurring costly component replacement and expensive equipment downtime. Fretting is defined as accelerated surface damage occurring at the interface of contacting materials subjected to small os...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...
