workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

Many different Parallel kinematic machine architectures have been proposed, but few have actually been used in production environments. The class of machine structures referred to as hybrid parallel kinematic machines have been more successful than most and have been employed in a wide variety of applications. These machines are however still affected by many of the limitations associated with ...

The multicanonical method has been proven powerful for statistical investigations of lattice and offlattice systems throughout the last two decades. We discuss an intuitive but very efficient parallel implementation of this algorithm and analyze its scaling properties for discrete energy systems, namely the Ising model and the 8-state Potts model. The parallelization relies on independent equil...

the early cytokines production in response to live logarithmic and stationary phase promastigotes of leishmania major was examined on the peripheral blood cells of the healthy individuals. whole blood cultures were stimulated by either logarithmic or stationary phase promastigotes. ifn- and il-10 productions were assessed by specific sandwich elisa. the results showed that the logarithmic prom...

objective: as the aqueous extract of capparis spinosa (cs) possess antidiabetic effect, he present study aims to reveal the possible  mechanism of action of cs in diabetic mice.materials and methods: both single and repeated oral administrations of aqueous extract of cs were performed in multi-low dose streptozotocin-induced (mlds) diabetic mice. euglycemic hyperinsulinemic clamp was used in as...

the history of mankind is intertwined with war. what distinguishes man from other creatures is his ability to dominate and capture the nature; he accomplishes this though using his rationale and making tools which set the ground for production and accumulation of capital. to protect his benefits and accomplish his desire for dominance, man creates weapons which become more developed parallel to...

In most database systems with production rule facilities, rules respond to operations on centralized data and rule processing is performed in a centralized, sequential fashion. In parallel and distributed database environments, for maximum autonomy it is desirable for rule processing to occur separately at each site (or node), responding to operations on data at that site. However, since rules ...

The analysis of workload traces from real production parallel machines can aid a wide variety of parallel processing research, providing a realistic basis for experimentation in the management of resources over an entire workload. We analyze a ve-month workload trace of an Intel Paragon machine supporting a production parallel workload at the San Diego Supercomputer Center (SDSC), comparing and...

Writing data in parallel is a common operation in some computing environments and a good proxy for a number of other parallel processing patterns. The duration of time taken to write data in large-scale compute environments can vary considerably. This variation comes from a number of sources, both systematic and transient. The result is a highly complex behavior that is difficult to characteriz...
