Development of a Two-Temperature Mathematical Model of Plasma Processes in a Discharge Chamber of a Multi-chamber Arrester Operating in Conditions of Mountain Areas

This article is devoted to a development of a mathematical model of plasma processes in a discharge chamber of a multi-chamber arrester operating under reduced pressure. The results obtained using this model will make it possible to develop recommendations on modifying the design of multi-chamber arresters for operation in conditions of mountain areas.A composition, thermodynamic and transport properties of plasma for the two-temperature model were calculated on the basis of the data on the materials of the discharge chamber and on the basis of the experiments performed earlier.The paper presents the results of calculations i.e. distributions of discharge voltage and electrical conductivity on time at various pressures. A comparison of obtained results was carried out

Parallel search for signals with specified cross- and autocorrelation properties on multiprocessor platforms

The article introduces the program application for seeking binary signals of specified bit length that have specified correlative properties. The application seeks these codes using parallel (multithreaded) permutation of the possible values from all of the range specified by a bit length. The article contains the results of researches of speed parameters of the permutator working in single–threaded and multithreaded modes. Analysis was made for multithreaded specific conditions of speed reductions. The researches are made according to the priority national project "Education" in the centre of high performance computations of the Far Eastern National Technical University. The centre allows parallel computations in remote access
