THE RESULT’S PROCESSING Of THE OBSERvATIONS Of THE CRUSTAL BLOCKS’ RELATIvE DISPLACEMENTS WITH THE AID Of THE CRACK GAUGE TM -71
crack gauge TM-71, relative observations, control-measurement system, computer programm
Abstract.Geodynamic investigations concerning the registration of the displacements of the geological structures are arranged in the Sudety Mts. and the Fore-Sudetic Block by research workers. These investigations are conducted in the appropriate measurement and control system. One of the segments of this system applies to the observations of the relative displacements of the adjoining geological structures. For this purpose, there is used a special gauge mounted permanently in situ. In objective researches there is used the crack gauge TM-71. This device is used for his periodical readings the phenomenon of light interference(Moiré effect). The objective researches have been conducted since the 70s of the 20th century. As far as processing of the results is concerned, it was based on manual calculations of the registered changes in the three dimensional local space x, y, z. In this paper, there is presented the algorithm of calculations together with the own computer application for processing the results of periodical observations made with the aid of the crack gauge TM 71.
The valuation of real property and its components is within the interest of many scientific disciplines. Property valuers are mainly lawyers, economists and land surveyors. The science they create engages, however, all these so different and remote areas, in a natural way, for the common benefit, and the property valuers’ knowledge is interdisciplinary. On the other hand, one can advance a thesis that no one can substitute land surveyors in numerical calculations connected with elaboration of observations. That is why real property valuation has permanently integrated with the broadly defined geodesy. In the time of economic recession, the economic development downturn results in the reduction of demand for the real property as well as lower interest in services of people qualified in the field of real property market. The community of real property valuers needs new areas of activity. Since there is no such a situation in the market that no financial statement would be necessary to be drawn up, the author, in her considerations, attempts to present the issue of valuation for accounting purposes, basing on both the domestic and international legal regulations. The latter should be strictly taken into account by valuers when engaging in the valuation for accounting purposes. The paper discussed the source of national (accounting act, NVS) and international (IVS, IAS) law from which the knowledge in the valuation of assets benefited the appraiser should take. Analysis supports the earlier publications.
Real eState market DynamicS anD Determination of creDit risk
key words: real estate market, real estate value, mortgage loan
Abstract . The purpose of this paper is to focus attention on the question of safety of banks that finance actions in the real estate market. Negative effects of recession in the real estate sector are reflected in the banking sector. The intensity of the problem depends greatly on the level of risk at which credits were managed just before the turning point. Apart from complying with the standard regulations governing the banking sector, the activity within the market in question spawns the necessity for creditors to identify a given environment and the related risk. Therefore, it can be concluded that one of the options of securing oneself against the loss of assets is to conduct a reliable market tendencies analysis and to continuously monitor information coming from this market. It should be noticed that mortgage loans are a great source of significant information on the issue of repayment efficiency. Based on this information one can formulate conclusions concerning the validity of crediting terms and coditions. One can also estimate the probability of non-payment of loans. The credit risk associated with secured mortgage claims determined by banks strictly depends on capabilities of potential debtors, but also on the value of a property. It is therefore important that creditworthiness should be determined correctly in the current economic circumstances, and the market value of a mortgaged property should be accurately estimated.
ACCURACY EVALUATION OF QUASI-GEOID FROM EGM08 MODEL FOR AREA OF POLAND
EGM08, quasigeoid heights, ellipsoidal heights, normal heights
The paper presents the evaluation results for the new Earth Gravitational Model EGM08 that was recently released by the US National Geospatiat Intelligence Agency. Tests were carried out using GPS network POLREF covering in uniform way the territory of Poland and precise traverse established by Institute of Geodesy and Cartography in 2005. Sites of POLREF network and sites of traverse were tied to the Polish vertical reference frame. Our results reveal that EGM08 offers a major improvement (more than 80%) in the agreement level among quasigeoidal, ellipsoidal and normal heights over the area of Poland, compared to the performance of previous combined GGMs for the same area.
