The StarTech massively parallel chess program, running on a 512-processor Connection Machine CM-5 supercomputer, tied for third place at the 1993 ACM International Computer Chess Championship. StarTech employs the Jamboree search algorithm, a natural extension of J. Pearl’s Scout search algorithm, to find parallelism in game-tree searches. StarTech’s work-stealing scheduler distributes the work...

Pulse Width Modulated (PWM) voltage source inverters (VSIs) are extensively used in industrial and domestic applications. The versatile natural sampled sinusoidal PWM (SPWM) method can perform output voltage control with acceptable indices. In these PWM-VSI, the coarse voltage regulation is done with change in modulation depth while fine voltage regulations have not been addressed by other auth...

Several research effort has been devoted to increase the performance of the relational database systems. Various types of database machines were so far proposed. Among them, shared nothing parallel database system such as Teradata, GAMMA, TANDEM are actually implemented and detail performance evaluation is undergoing. On the other hand, recently massively parallel processor like the Connection ...

The paper deals with the modeling of processes charge-discharge battery assemblies taking into account their degradation. results simulating cyclic operation in Electronics Workbench electronic laboratory are presented, possible schemes inclusion given, and options for re-switching batteries during considered as well connecting additional elements to extend life connection. simulation took pres...

In an electrical energy storage and delivery system, a parallel connection of battery modules can be used to increase the storage capability and power delivery demands. Parallel connection of batteries requires a robust battery management system as batteries may have different operating parameters such as state-of-charge (SoC), open-circuit voltage (OCV), internal resistance or battery chemistr...

We classify 7-dimensional cocalibrated G2-manifolds with parallel characteristic torsion and non-abelian holonomy. All these spaces admit a metric connection ∇ with totally skew-symmetric torsion and a spinor field Ψ1 solving the equations in the common sector of type II superstring theory. There exist G2-structures with parallel characteristic torsion that are not naturally reductive. 1. Metri...

A parallel algorithm for solving the multinephron model of the renal inner medulla is developed. The intrinsic nature of this problem supplies suucient symmetry for a high-level parallelism on distributed-memory parallel machines such as the iPSC/860, Paragon, and CM-5. Parallelization makes it feasible to study interesting models such as the rat kidney with 30; 000 nephrons. On a high-end work...

Most existing inductive learning systems form concept descriptions in propositional languages from vectors of basic features. However, many concepts are characterized by the relationships of individual examples to general domain knowledge. We describe a system that constructs re-lational terms eeciently to augment the description language of standard inductive systems. In our approach, examples...

The rotation precision of rotors determines the efficiency and quality overall aero-engine, as well its long-term reliable operation ability. As terminal link aero-engine manufacturing, assembly is last guarantee control. Rotor relates to accurate expression connection form design optimization scheme. existing variation model cannot adequately handle partial parallel chain problem, ignoring bay...
