    Models for Embedded Repairing Logic Blocks
    (EWDTS, 2012) Hahanov, V. I.; Frolov, A.; Litvinova, E. I.; Tiecoura Yves
    The models of combinational circuits, focused on solving practical problems of embedded repairing components of the logic units are proposed. The logical circuit is complemented by operational and control automata for modeling digital devices, which increases processing time and hardware costs for creating a wrap of addressable elements. The structures can also be used for hardware modeling functionalities of digital projects by using PLD, which allows improving the performance of software model verification. The proposed solution of embedded gate repair for combinational circuits makes it possible to comprehensively solve the problem of autonomous repairing digital systems on chips due to the time and hardware project redundancy.

    Solar Simulator for Photovoltaic Devices Based on the Electrodeless Sulfur Lamp
    (2018) Frolova, T. I.; Frolov, A.
    At the present time, there has been an active growth in the use of solar energy, which is the most affordable renewable energy source for us. In this regard, there is a need for testing of photovoltaic cells and solar panels used to collect solar energy. In laboratory conditions, when testing photovoltaic panels, it is necessary to use solar simulators, which have very close parameters to solar radiation. The most important components of solar imitators are artificial light sources. Within this work, the reference spectral distribution of sunlight in the visible optical range at the level of AM 1.5G was shown, as defined in ASTM Gl73-03. The goal of this work is to determine the output characteristics (spectral match and spatial non-uniformity of irradiance) of the solar simulator based on ASTM E927-10 standard in the interval of 400 nm - 700 nm. As a light source of the solar simulator, a powerful electrodeless sulfur lamp with microwave excitation is used which has a continuous quasi-solar spectrum of optical radiation with a maximum at 510 nm and is very close to the solar spectrum in the visible range.
