Документ Результаты сравнения разработанной теоретической модели нижней части области F ионосферы с эмпирической моделью А. Д. Данилова(НТУ "ХПИ", 2004) Живолуп, Т. Г.Comparison of the elaborated theoretical model of the ionosphere F-region lower part with the A. D. Danilov empirical model is considered. Comparison results of the experimental and theoretical height profiles give evidence about good accuracy characteristics of the elaborated theoretical modelДокумент Обоснование характеристик радара для определения скорости дрейфа ионосферной плазмы методом некогерентного рассеяния(НТУ "ХПИ", 2004) Емельянов, Л. Я.The aspects of ensuring of reliable ionospheric plasma drift velocity measurements by incoherent scatter method are considered. The substantiation of some parameters of IS radar is presenteДокумент Гафний - перспективный материал для ядерной энергетики(НТУ "ХПИ", 2004) Ефимов, Александр Вячеславович; Ажажа, В. М.; Пилипенко, Н. Н.; Мухачев, А. П.The basic nuclear-physical properties of hafnium as perspective absorber material for regulatory authority of nuclear reactors are considered. Fluoride calcium thermal technology of obtaining of high pure hafnium, which mastered in Ukraine is analyzed. The basic physical-mechanical properties and chemical composition of not imported hafnium in comparison with metal of foreign production are represented. With the purpose of improvement of the quality of metal was offered and carry out the complex of researches on advancing metallurgical processes of obtaining high pure hafnium and its deformation processingДокумент Универсальный измерительный блок для изучения трех фотоэффектов на монохроматоре УМ-2(НТУ "ХПИ", 2004) Ушаков, В. В.; Корж, Ирина АнатолиевнаBy way of extending of functional mobility and didactic capacity of educational equipment the laboratory device based on monochromator УМ-2 for learning three kinds of photoeffect - external (with vacuume phototube, or photoelectronic multiplyer), internal(with photoresistor) and ventil (with photodiode) is actualized. Alternation brings to effect by adequate commutation of apparatus and elements on the stand. Computation of the optimal duty of ventil photoelement and Plane constant is realized on PCДокумент Регистрация показаний спектрофотометра СФ-46 с использованием ЭВМ(НТУ "ХПИ", 2004) Шкалето, Владимир Иванович; Копач, Галина Ивановна; Харченко, Н. М.; Карасёв, С. Н.The circuit of the interface unit of a computer with a spectrophotometer СФ-46, using the universal voltmeter B7-23 is described. The device is intended to automatic registration results of measurement spectral dependencies of a transmittanceДокумент Анализ ошибок измерений при зондировании ионосферы методом HP в режиме сдвоенных импульсов(НТУ "ХПИ", 2004) Рогожкин, Евгений Васильевич; Белозёров, Д. П.The features of measurements of parameters ionosphere incoherent scatter are analyzed in the article. The capability of account of high-altitude profiles autocorrelation functions transformations measuring during incoherent scatterДокумент Определение ионосферных параметров в методе HP на основе использования искусственных нейронных сетей(НТУ "ХПИ", 2004) Пуляев, Валерий АлександровичQuestions of the using neural networks for the solution of an electrodynamics return problem of an ionospheric parameters definition by an incoherent scatter method. Architecture of neural network is shownДокумент Результаты наблюдения аномальной ионосферной бури 21 марта 2003 года на харьковском радаре некогерентного рассеяния(НТУ "ХПИ", 2004) Пазюра, С. А.The study results of variations of ionosphere parameters, accompanied a magnetic storm with the main phase on March 21,2003 are presented. Data are obtained with the Kharkov incoherent scatter radar. According to time variations of concentration, velocity, ion temperature of solar wind, induction of IMF measured on artificial satellite "ACE" indices the details of magnetic and ionosphere storms are restoredДокумент Расчет мощности лазера и параметров оптических схем ЛДИС(НТУ "ХПИ", 2004) Никитин, А. М.Estimated calculation of the radiation power is adduced, permitting to receive a steady signal of a laser Doppler anemometer (LDA), for the optical systems adapted to measurements of flows characteristics in the composite channel power and heat engineering of the equipment. Efficiency of algorithm at a phase of layout LDA optical schemes is shownДокумент Перспективы применения ионозонда в составе радара некогерентного рассеяния Института ионосферы(НТУ "ХПИ", 2004) Лысенко, В. Н.; Скляров, И. Б.Features of automatic ionospheric stations operation jointly with IS radar are considered. The information obtained after digital processing allows to essentially increasing ionospheric data quality
