Optimization of iterative calculus over large arrays in multiprocessor systems

Autor: Cristian Abrudean

Publikováno v: AIP Conference Proceedings.

Many numerical simulation problems involve processing of large arrays of numbers or data structures, usually representing a discretization mesh. Each iteration over the large array is equivalent to a time step, which is then repeated until the entire

Modeling and experimental investigations of a reactive homo-heteropolar brushless synchronous machine

Autor: Gabriel Nicolae Popa, Lucian Nicolae Tutelea, Cristian Abrudean, Sorin Ioan Deaconu, Marcel Topor

Publikováno v: 2009 35th Annual Conference of IEEE Industrial Electronics.

In this work is presenting a reactive homo-heteropolar brushless synchronous machine (RHHBSM), with stator excitation destined to operate as low power generator in hydroelectric, or wind power stations, or as servomotor with reduced inertia. We propo

A Case Study of ESP Electrical Characteristics from a Thermal Power Station

Autor: Iosif Popa, Cristian Abrudean, Gabriel Nicolae Popa, Sorin Ioan Deaconu, Victor Vaida

Publikováno v: IAS

For a thermoelectric power plant was made an analysis upon plate-type electrostatic precipitators (ESPs) for an energetic group depending on the group's load, in different operation regimes of the high-voltage units. Knowing the ESP's real I-V charac
