W artykule przedstawiono model diody zastosowany w programie PSpice. Podano podstawowe zależności opisujące charakterystykę statyczną oraz przełączania diody. W oparciu o program PARTS zaprezentowano charakterystyki pomiarowe na podstawie, których program oblicza parametry opisujące model. Wyniki pomiarów charakterystyk rzeczywistej diody, porównano z danymi znajdującymi się w bibliotece elementów PSpice. .

The article presents structure model of diodę used in program PSpice. There were delivered basic dependences describing statical and switching characterization of diode. On base of program PARTS were presented measuring - characterizations on the ground of which program calculates parameters model. Results of measurements - characterizations of real diode was compared with data from elements library of program PSpice.

Clinical investigations yield huge amount of experimental data which need appropriate processing. High degree of their variability decreases quality of prognostic and classification results. Frequently problem of strong redundancy of variables incorporated into model occurs, produces computational instabilities and in multifactorial models makes the appropriate interpretation of obtained results hindered. In this paper we present the set of mathematical procedures used in comparative analysis of two treatment methods for patients with advanced cervical cancer: radiotherapy and combined treatment of ionizing irradiation and chemotherapy.

The prevalence of clusters with the increased morbidity rate is the area of interest among epidemiologists. Not only does the identification of clusters require collecting precise epidemiological data but it also requires the application of reliable spatial statistics techniques. The identification of atypical clusters in this article is performed using data from the Polish Registry of Congenital Malformations (PRWWR) on children with isolated cleft lip with or without cleft palate; the study was carried out in the Wielkopolska Region (Greater Poland). For this purpose, Kulldorff Scan Statistics and the LISA method were used. Since each technique used in the study focuses on a slightly different aspect of spatial structure, the obtained clusters do not always completely overlap. This study presents and compares the efficiency and accuracy of these two non-standard methods of geo-static analysis in children living in the Greater Poland counties. The study has identified 5 agglomerations with an increased prevalence rate of the examined malformation, no statistically significant cluster has been detected. On the basis of the agglomerations, it was possible to compare the applicability of two statistical methods used in the study. Despite the fact that the located clusters do not always completely overlap, the study has proved similarity in qualifying particular counties for given clusters and areas outside the clusters. Taking into account its applicability and monitoring the process of spatial scanning, the Kulldorff method has occurred more universal and accurate in examining the children with congenital malformations.
