Implementation analysis of ERP system Infor M3 in international company
Hoffmann, Jakub ; Basl, Josef (advisor) ; Černoch, Pavel (referee)
This thesis analyzes the implementation of the ERP system Infor M3 in international company. The main objective is to analyze the current implementation causes of delay and to recommend measures for future implementation stages to prevent them. The main objective of theoretical part is to analyze global ERP market and summarize available implementation methodologies of ERP systems. Second objective of theoretical part is to analyze the frequent causes of delays in implementation's projects in general and to summarize the basic methods for searching the causes of problems. Practical part is based on knowledge from theoretical part and through a survey identifies the most serious causes of delay in implementation in particular international company. The outcome of this thesis are recommendations for the rest of this implementation project to avoid and prevent the same causes and problems and allow to finish project implementation in time.

Optimalizace detekce sekundárních elektronů segmentovým ionizačním detektorem v environmentálním REM
Černoch, P. ; Jirák, Josef
The article deals with a prezentation of results of optimization of secondary electron detection by an ionization detector in the environmental scanning electron microscope. The ionization detectors consisting of a varied electrode geometry and varied voltages on these electrodes, named segmental ionization detectors, are presented as a possibility to reach desired contrasts in a specimen image. In this work, images acquired by several detectors demonstrate detection of different types of signal electrons utilizing a specimen containing thin surface layers and a specimen made for a material contrast measurement.

Detekce signálu segmentovým ionizačním detektorem
Černoch, P. ; Jirák, Josef
This article deals with signal detection by a segmental ionization detector. Changes of image contrasts in a dependency on different potentials on electrodes of the segmental ionization detector are studied. Electron trajectories in an electrostatic field in a vacuum simulated via program Simion 3D 7.0 are considered during the experiment.

Detekce signálu použitím segmantového ionizačního detektoru
Jirák, Josef ; Černoch, P. ; Autrata, Rudolf
For signal electrons detection at environmental conditions, it is often used a detector that utilizes impact ionization in the gaseous environment of a specimen chamber for a signal amplification. An electrostatic field created in a space between a grounded specimen and a detector electrode provides the energy needed for efficient ionization of secondary electrons. A voltage of several hundred volts is attached to the detector electrode. It was proposed an electrode system of a ionization detector, with several concentric electrodes divided into two halves - right and left. It was shown that the higher diameter of the electrodes brings an increased contribution of backscattered electrons to the detected signal. Different contrast mechanisms were studied
