Item Determination of Stokes coefficients according to the GOCE satellite(Видавництво Львівської політехніки, 2013) Lopushansky, AlexanderThe last achievements of the satellite geodesy is the project of European Space Agency – the GOCE satellite mission (Gravity of field and steady – state of Ocean Circulation Explorer) which is using the satellite gradientometry method. The gravitational field of the Earth is represented traditionally as a finite series of spherical harmonic functions of the gravitational field model of the finite number of parameters Cnm, Snm. The corresponding coefficients Cnm, Snm were derived based on the second Neumann method including the construction of Gauss-Legandre grid.Item Conditioning and dewatering for sewage sludges from treatment fasilities in the town of Brody in Lviv region(Видавництво Львівської політехніки, 2013) Verbovskiy, Orest; Ivaniv, VasylThe influence of chemicals and their doses on filtration characteristics of sewage sludges in the town of Brody in Lviv region is determind.Item Vibrations of axially compressed sandwich beam due to a moving force(Видавництво Львівської політехніки, 2013) Misiurek, Katarzyna; Śniady, PawełThe dynamic response of a finite, simply supported axially compressed sandwich beam subject to a force moving with a constant velocity is investigated. The classical solution has a form of an infinite series. The main goal of this paper is to present that the aperiodic part of the solution can be presented in a closed form instead of an infinite series. The shown method of finding the solution when the form is closed is based on the observation that the solution of the system of partial differential equations in the form of an infinite series is also a solution of an appropriate system of ordinary differential equations. The closed solutions take different forms depending on the velocity v of the moving force is smaller or bigger than the shear-wave velocity of the beam. The dynamic response of the sandwich beam under moving force is very important solution. It is because that it can be used also in order to find the solution for other types of moving loads.Item Research of opportunities of absolute positioning PPP technologies when dealing with the change of city boundar(Видавництво Львівської політехніки, 2013) Zademlenyuk, Antonina; Avramenko, AnatoliyThe article focuses on researching the accuracy of the method of absolute positioning PPP (Precise Point Positioning). Application results of the method are described.Item Index of authors(Видавництво Львівської політехніки, 2013)Item Late 18th – mid 20th centuries manor houses in Ukraine(Видавництво Львівської політехніки, 2013) Yakubovskyy, IhorThe paper analyzes the main directions of Ukrainian manor house development as well as defines the place of manor housing in Lviv on the Ukrainian historical background. The approaches to urban manor houses preservation are proposed.Item Environmental impact assessment of combustible wastes utilization in rotary cement kilns(Видавництво Львівської політехніки, 2013) Khrunyk, SofiyaThis study focuses on the environmental impact assessment of the coal combustion and its substitution by alternative fuels from combustible wastes during Portland cement clinker sinterization in rotary cement kiln. Environmental impact assessment was carried out based on the fuels chemical composition and operating parameters of a rotary cement kiln in accordance with EURITS and IMPACT 2002+ methods.Item Walkways analysis of “Złote Tarasy” mall in Warsaw(Видавництво Львівської політехніки, 2013) Berezko, OlenaSince their appearance and till today shopping malls have undergone significant transformations. This is reflected in contemporary studies where malls are divided into four generations. In this paper the walkways of “Złote Tarasy” mall in Warsaw are analyzed. The mall belongs to the fourth generation and is a prominent representative of the modern approach to malls construction. Based on our studies certain principles and features of architectural design of fourth generation malls’ walkways where formulated. These results can be used in designing this type of malls.Item Mathematical model of stress and deformation state of glued anchorage of reinforcement bars in cases of exposure short and long term loading(Видавництво Львівської політехніки, 2013) Shyshkin, Eduard; Zolotov, MykhayloThe solution of axisymmetric task of the theory of elasticity for the case of embedment of reinforcement bars into concrete of crescent type by acrylic glues, allowing to determine tensions and deformations both on contacts glueanchor, glue-concrete and in the concrete body has been proposed. It has been taken into account that at long-term loading the behaviour of acrylic glues co-ordinates the linear theory of creep. The results of calculation experiment are presented.Item Use of modern finite element analysis packages in calculations of reinforced concrete bridges(Видавництво Львівської політехніки, 2013) Volotsiuga, Volodymyr; Shynder, YuliyaThis article deals with the use of modern finite element analysis package in calculation of reinforced concrete bridges. The static elastic calculations of reinforced concrete bridge girder was being performed in Femap-Nastran NX.
