NUT FOR THREAD STOP

چکیده
Abstract. In engineering products, a significant part of the connections are formed using threaded connections, functioning which largely determines reliability mechanisms and assemblies. To preserve invariability tightening during operation vehicles, nut is presented, in internal thread divided into two parts with different geometric parameters. Nut profiles made profile heights described. The first height equal to initial contour sharp vertices, other one standardized rounded vertices. When assembling connection between increased working diameter bolt thread, necessary tightness provided. zone upper section outer nut, metal elastically deformed, therefore, when connected, an interference increase coefficient friction, operational connection. optimal ratio lengths sections has been determined ensure locking properties depending on specific operating conditions vehicles. Conducted laboratory studies specially stand showed scientific hypothesis, suggesting that stability depends changes physical parameters associated distortion crystal lattice density dislocations occur process formation particular technology its operation. . A technique for accelerated testing based creation additional unscrewing torque developed, can significantly reduce amount predict time after it re-tighten designed repeated use reassembly retention repair various technical devices, including cars. production proposed simple economical involves universal screw-cutting equipment available at any company. further studies, planned conduct long-term tests vehicles order confirm same as achieving simplicity product high manufacturability.

We present the design and implementation of Arachne, a threads system that can be interfaced with a communications library for multi-threaded distributed computations. In particular, Arachne supports thread migration between heterogeneous platforms, with dynamic stack size management and recursive thread functions. Arachne is eecient, exible and portable | it is based entirely on C and C++. To ...

In this paper we classify simultaneous multithreaded architectures based on how they select instructions issued in a single cycle. This classiication allows us to study the present trend of technology as well as to explore the new avenues for improvements in simultaneous multithreaded architectures. Based on our classi-cation, we study the impact of various parameters of simultaneous multithrea...

With the current trend toward multicore architectures, improved execution performance can no longer be obtained via traditional single-thread instruction level parallelism (ILP), but, instead, via multithreaded execution. Generating thread-parallel programs is hard and thread-level speculation (TLS) has been suggested as an execution model that can speculatively exploit thread-level parallelism...

In 1994, we presented extensions to MPI and offered an early paper on potential thread extensions to MPI, as well as non-blocking collective extensions to MPI [14]. The present paper is a thorough review of thread issues in MPI, including alternative models, their computational uses, and the impact on implementations. A number of issues are addressed: barriers to thread safety in MPI implementa...
