Orthorectification and geometric verification of high resolution TerraSAR-X images
(2011) Badurska, Monika
TerraSAR-X is a German radar satellite, which was launched in June 2007. The satellite is equipped with a modern SAR system using the X band microwave radiation frequency and is capable of acquiring very high resolution SAR images independent of weather conditions and illumination. The paper presents the results of geometrical correction of high resolution TerraSAR-X images. The research was based on images acquired in HighResolution SpotLight mode in single polarisation HH with spatial resolution about 1 m. In orthorectification process the data supplied by the distributor in the SSC format was used. The results of orthorectification using various amount of ground control points was checked. The influence of the digital terrain model used in orthorectification process was also analysed. The last part of the work presents verification of geometric precision of geocoded product (EEC) generated by the distributor.
The problem of the energy efficiency and renewability in applying heat pumps, referring to the European Union Directive
(2011) Barbacki, Antoni
The article presents the requirements contained in the European Union Directive 2009/28/WE for the systems such as heat pumps to be able to classify their effect as the management of renewable energy. The Directive also introduces a legal requirement that the installations with heat pumps are energy efficient. Only pumps fulfilling the mentioned above conditions shall be regarded as using energy from renewable resources the value of which will be considered at calculating the contribution of renewable energy in the total gross energy production. In this context also the speculations concerning the issues of renewability, emission and economics during the exploitation of heat pumps were presented. The general conclusion form the presented speculations is that both the level of renewability, emission and economics of the application of heat pumps are strictly connected with the high value of the coefficient of performance (COP), depending on climatic conditions and the applied low temperature source.
Analysis of dynamic strains of suspension bridge on the example of pedestrian footbridge
(2011) Ćwiąkała, Paweł; Kuras, Przemysław; Kuras, Olga Magdalena
Artykuł omawia podstawowe zasady działania nowoczesnego naziemnego radaru interferometrycznego, wchodzącego w skład systemu IBIS-S, oraz możliwości zastosowania go w pomiarach konstrukcji. System ten zapewnia wysoką dokładność, ciągłą rejestrację oraz jednoczesną obserwację wielu punktów, dzięki czemu znajduje zastosowanie do badania dynamiki obiektów. Artykuł prezentuje i omawia wyniki pomiarów drgań pionowych i skrętnych przeprowadzonych na kładce dla pieszych o konstrukcji wiszącej. Wykonane badania potwierdziły dokładność i przydatność naziemnego radaru interferometrycznego do pomiarów drgań.
Application of difference analysis perception in comparison of calculation of the effects of floods
(2011) Dąbrowski, Janusz
The article presents the application of difference analysis perception in comparison of calculation of the effects of floods. The year 2010 was for Poland particularly acute in terms of flooding, which resulted in damage to the infrastructure of many communities. In the case of damage to the state property, a local government authority may apply for grants to remove these effects. The data contained in the work makes up a collection of 142 pairs of independent calculations of the effects of flooding on the Podkarpackie province. The first calculation was made by specialists in a municipality, and the second verification by the committee representing the interests of the State in the person of the Governor. The basis of calculations was the data from the Secocenbud. The difference analysis is usually applied while comparing two independent perceptions describing the same value. Surveyors often use the difference analysis perception in measurement of angles, length and height differences. While property estimating, the difference analysis perception is hardly used due to lack of relevant data. The data compiled and presented by the author concerns calculations made in late May and June 2010, with dozens of municipalities of the Podkarpackie province. With so little time-interval we have completely ignored in the analysis the impact of the economic and environmental impact on the value of real estate valuation. An additional advantage of the analysis is the fact that all the valuation estimates mainly the effects of flooding in relation to road infrastructure. With such a selection of data it was possible to carry out a thorough analysis of differences in perceptions. The article shows a certain regularity associated with the valuation of the effects of floods being so far in the field of speculations and assumptions due to lack of data. Based on the data and its interpretation, the article contains practical proposals for local and state government.
Screening study of life cycle assessment (LCA) of the electric kettle with SimaPro software
(2011) Grzesik, Katarzyna; Guca, Kinga
Life cycle assessment is an important tool to evaluate possible impacts associated with products. LCA is a 'cradle-to-grave' approach, it addresses the environmental aspects and potential impacts throughout a product's life cycle from raw material acquisition through production, use, end of life treatment, recycling and final disposal. The goal of this paper is conducting the screening LCA of the popular electric kettle, Zelmer model 17013, manufactured, used and disposed in Poland. Data on the kettle structure and its components was obtained from service manual and from the technical data on this model published by the manufacturer. The screening LCA was conducted with SimaPro software, a professional tool to collect, analyze and monitor the environmental performance of products, in which life cycles could be modeled in a systematic way, following the ISO 14040 standards. The LCA results show that 99% of the total environmental impact during the entire life cycle of the electric kettle has the use stage of the product, that is consumption of electricity produced in Poland. All efforts to improve the environmental performance of this product should be put in optimising the use phase that is to minimize the electric energy consumption. The presented LCA is a screening study using already available data in SimaPro databases. Conducting the extensive study was not possible due to the lack of exact and detailed data. The study results have some limitations and definitely cannot be used to compare products.
