Fast reconstruction of the elementary particle tracks for the cosy-tof experiment

Borodina E.I.

Abstract

Self-sufficient software package TOF-ONLINE for online visualization and preliminary data processing for experiments at COSY-TOF particle detector at COSY accelerator was developed. It automatically controls the detector elements functionality during data acquisition at the experiment, visualizes the detectors key parameters and creates geometrical reconstruction of the tracks of produced elementary particles in the context of the detector geometry. This work describes in details the algorithms of the final stage - the track reconstruction.

Polarization of samples of the paint and varnish covering

Hodjakov A.A., Aby-Nidzdim R.K.

Abstract

The mechanism of polarization of a lacquer coating is studied. It is established that polarization is caused by localization of charges, both in a thin blanket, and in covering volume. Electric resistance of samples has made 5.6 ⋅ 1017-5.6 ⋅ 1018 Ohm ⋅ cm, energy of activation responsible for a charge relaxation электрически active defects - 1.2 eV.

The influence of the substrate temperature change character during the growth on the topology of the Ge/Si(100) film surface

Lunin L.S., Bavizhev M.D., Sysoev I.A., Lapin V.A., Kuleshov D.S., Malyavin F.F.

Abstract

The possibility of roughness reducing of the Ge/Si (100) film using low-temperature layer of Ge (LT-Ge) has been investigated. It was shown that the substrate temperature change character during the growth process influences on the surface morphology of the grown Ge/LT-Ge/Si films. Samples were obtained by the method of molecular-beam epitaxy.

A new integrated power plant with a small scale turbine for the Organic Rankine Cycle

Belozerov A., Kley M., Leschber Y., Rieger R., Shatalov I.K., Wiedmann M.

Abstract

Combined heat and power (CHP or cogeneration) describes the simultaneous generation of electrical power and heat. CHP has been well established for medium and high power ranges (> 100 kW el. power). The Kompakte Dampf Turbine (KDT, meaning compact steam turbine) addresses the low-end of power generation (~2 kW el. power). The KDT is a highly integrated power plant of small dimensions able to use various heat sources. Its simple design promises a low-cost CHP for residential homes.

The large deflections of the previously intense ideal plastic beams with the regional moments

Basov U.K., Monakhov I.A.

Abstract

In the work up the technique of the decision of problems about the large deflections of beams from ideal hard-plastic material, with various kinds of fastening, for want of action of the asymmetrically distributed loads with allowance for of preliminary stretching-compression is developed. The developed technique is applied for research of the strained-deformed condition of beams, and also for calculation of a deflection of beams with allowance for of geometrical nonlinearity.
