چکیده
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 facilitate heterogeneous thread operations, we have added three keywords to the C++ language. The Arachne preprocessor takes as input code written in that language, and outputs C++ code, suitable for compilation with a conventional C++ compiler. The Arachne runtime system manages all threads during program execution. We present some performance measurements on the costs of basic thread operations and thread migration in Arachne, and compare these to costs in other threads systems.

Thread Pitch Variant in Orthodontic Mini-screws: A 3-D Finite Element Analysis
Orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. Miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. Macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. In this study, a 3-D finite element analysis wa...

Evaluating the impact of length and thread pitch on the stress distribution in dental implants and surrounding bone using finite element method
longevity of osseointegrated implants are intensely influenced by biomechanical factors. Control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. In this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum Von Mises stress in implant-abutment complex and ja...
متن کاملSeismic behavior of semi-dry precast concrete connections using tapered thread couplers
The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...
