We have implemented a parallel graph reducer on a commercially available shared memory multiprocessor (a Sequent Symmetry TM ), that achieves real speedup compared to a a fast compiled implementation of the conventional Gmachine. Using 15 processors, this speedup ranges between 5 and 11, depending on the program. Underlying the implementation is an abstract machine called the h ; Gi-machine. We...

The planetary reducer is a common type of transmission mechanism, which can provide high accuracy and has been widely used, it usually required with reliability characteristics in practice. During the manufacturing usage stages reducers, uncertainties are ubiquitous wear inevitable, affect reducers. In this paper, belief modeling analysis considering multi-uncertainties proposed for Firstly, ba...

In aero-engines, a secondary air system is used to cool the rotor discs and seal cavities between stator parts. The pressure loss caused by bleed can be effectively reduced setting finned vortex reducer. Thus, design optimized researching flow structure of each section in cavity with this study, influence different installation positions reducer on characteristics was investigated through exper...

Abstract Anti-mud agents could improve the efficiency of action water reducers in concrete by preferentially. The anti-mud agent was preferentially adsorbed on clay surface, which reduces ineffective adsorption reducing to paste, thereby improving reduction efficiency. However, its application high-sediment content coal gangue gypsum backfill materials had not been reported. In this paper, comp...

This paper presents the design process and driving performance test results of a power-assist module to which cycloidal reducer is applied in order convert manual wheelchair into an electric wheelchair. The types electrification modules currently used electrify wheelchairs include front-mounted, rear-mounted, powered wheels. These assist devices are either difficult carry transport independentl...

MapReduce has become a popular model for large-scale data processing in recent years. Many works on MapReduce scheduling (e.g., load balancing and deadline-aware scheduling) have emphasized the importance of predicting workload received by individual reducers. However, because the input characteristics and user-specified map function of a given job are unknown to the MapReduce framework before ...

A novel method, for solving satisfiability (SAT) instances is presented. It is based on two components: a) An Epistasis Reducer Algorithm (ERA) that produces a more suited representation (with lower epistasis) for a Genetic Algorithm (GA) by preprocessing the original SAT problem; and b) A Genetic Algorithm that solves the preprocessed instances. ERA is implemented by a simulated annealing algo...

The GRIP architecture allows eecient execution of functional programs on a multi-processor built from standard hardware components. State-of-the-art compilation techniques are combined with sophisticated runtime resource-control to give good parallel performance. This paper reports the results of running GRIP on an application which is apparently unsuited to the basic functional model: a databa...
