Abstract:

Teorie odpovědi na položku (Item Response Theory, IRT) je souhrnné označení pro moderní psychometrické postupy, které již nejsou výhradní doménou tzv. výkonových testů. Ačkoliv v zahraničí jde o značně rozšířený přístup, v České republice jsou zatím metody standardizované prostřednictvím IRT jen ojedinělými pokusy. Přitom využití IRT neklade zvláštní nároky ani na psychometrika při tvorbě testu, ani na psychologa interpretujícího výsledky – spíše naopak. Za touto situaci možná stojí nedostatek domácích textů, které by v krátkosti představily základní výhody a možnosti IRT v podobě srozumitelné

Abstract:

The aim of this diploma thesis is to continue in prototype realization and a final proposition of three-phase frequency transformer pilot projected in scope of my bachelor work. This transformer is outlined for a small unsynchronized engine to 100 watt output and is designed to supply the fan motor. This suggestion was optimalized from the standpoint of bargain low price and technical feasibility. Powerful part of transformer is solved with help of circuit FSB50450 which is fed from compact source MYRRA 47155. Steering system is guaranteed with circuit MC3PHAC. This device is possible to use i

Abstract:

The conventional way of cryptanalysis is based on the cryptographic algorithms weak points examine. The attack model of conventional cryptanalysis covers mathematical description of the cryptographic algorithm used. This model is not with the relation to the physical model implementation and the real environment. Cryptographic algorithms currently used in the combination with strong cipher keys are almost unbreakable and the conventional cryptanalysis is ineffective. The new way of cryptanalysis employs the side channels. The model of cryptanalysis using side channels is enhanced with physical

This thesis is focused on dynamics of soft factors influencing workers during projects. These factors include motivation, workplace atmosphere, team synergy of workers and their emotions, and attribute of project manager who manages the project. Identification of soft factors and their relationships was achieved by examination of scientific literature in psychology and system dynamics. Description of managing project matters was achieved by examination of scientific literature dealing with project management. The main objective of this thesis is to create a dynamic model which simulates behavi
