A basic statistical analysis of the standard cross-validation procedure is not always conclusive. In the case of the investigated data set (which is inconsistent with normal distribution), three interpolation methods have been selected as the most reliable (according to standard cross-validation). However, maps resulting from the aforementioned methods clearly diff er from each other. This is the reason why a comprehensive statistical analysis of the studied data is a necessity. We propose an alternative approach that evaluates a broadened scope of parameters describing the data distribution. The general idea of the methodology is to compare not only the standard deviation of the estimator but also three additional parameters to make the final assessment much more accurate. The analysis has been carried out with the use of Golden Software Surfer. It provides a wide range of interpolation methods and numerous adjustable parameters.Item type:Thesis, Access status: Restricted , Badania podatności magnetycznej gleb na terenie Ciśniańsko-Wetlińskiego Parku Krajobrazowego(Data obrony: 2015-01-26) Gonet, Tomasz

The whole collection of the samples represents typical Carpathian soils – brown and sour. Magnetic susceptibility, frequency, dependence of magnetic susceptibility, temperature dependence of magnetic susceptibility, thermal decay of saturation, isothermal remanent magnetization, parameters of hysteresis loop and anhysteretic remanent magnetization of the samples were measured in a laboratory. Mass magnetic susceptibility of topsoil specimens is below 40 $\cdot$ 10$^{-8}$ m$^{3} \cdot$ kg$^{-1}$, which indicates that the investigated area is probably not polluted currently. The study of the samples from two soil profiles reveals a slight enhancement of magnetic susceptibility in the upper horizons, presumably related to natural processes. The temperature dependence of magnetic susceptibility and saturation isothermal remanence of four soil samples show that the presence of iron sulphide minerals (pyrrhotite) and maghemite is associated with hematite. The occurrence of other iron sulphide minerals in the soil is also possible. The saturation isothermal remanence curves do not confirm the presence of magnetite. Studies of the hysteresis loop reveal a significant role of paramagnetics among magnetic minerals occurring in the samples. Hysteresis parameters (coercive force, coercivity of remanence, saturation magnetization, isothermal remanent magnetization) and anhysteretic remanent susceptibility allowed the authors to evaluate the grain size distribution and reveal the presence of pseudo-single domain (PSD) grains.Item type:Thesis, Access status: Restricted , Systemy ogrzewania kombi – współpraca różnych źródeł grzewczych(Data obrony: 2014-10-22) Gonet, Tomasz
