Ion beams provided by small accelerators for material synthesis and characterization
Macková, Anna ; Havránek, Vladimír
The compact, multipurpose electrostatic tandem accelerators are extensively used for production of ion beams with energies in the range from 400 keV to 24 MeV of almost all elements of the periodic system for the trace element analysis by means of nuclear analytical methods. The ion beams produced by small accelerators have a broad application, mainly for material characterization (Rutherford Back-Scattering spectrometry, Particle Induced X ray Emission analysis, Nuclear Reaction Analysis and Ion-Microprobe with 1 um lateral resolution among others) and for high-energy implantation. Material research belongs to traditionally progressive fields of technology. Due to the continuous miniaturization, the underlying structures are far beyond the analytical limits of the most conventional methods. Ion Beam Analysis (IBA) techniques provide this possibility as they use probes of similar or much smaller dimensions (particles, radiation). Ion beams can be used for the synthesis of new progressive functional nanomaterials for optics, electronics and other applications. Ion beams are extensively used in studies of the fundamental energetic ion interaction with matter as well as in the novel nanostructure synthesis using ion beam irradiation in various amorphous and crystalline materials in order to get structures with extraordinary functional properties. IBA methods serve for investigation of materials coming from material research, industry, micro- and nano-technology, electronics, optics and laser technology, chemical, biological and environmental investigation in general. Main research directions in laboratories employing small accelerators are also the preparation and characterization of micro- and nano-structured materials which are of interest for basic and oriented research in material science, and various studies of biological, geological, environmental and cultural heritage artefacts are provided too.

Financial analysis of FAST ČR, a.s.
Kubišová, Monika ; Daněk, Stefan Svatopluk (advisor) ; Jiránek, Petr (referee)
The aim of this bachelor thesis is to perform a financial analysis of the company FAST ČR, a.s. for the period of 2012 to 2015 together with a forecast of future development. The thesis is divided into three main sections. The first section contains an introduction to the financial analysis and defines the indicators and models used in the second section, which can also be called as a practical part. In this practical part the company is characterized firstly then the financial analysis itself is performed based on external information. In this sections the computed values are compared with the biggest competitor too. In the last part, the forecast of the future development of revenues is drawn up, it is derived from the market and used for planned income statement for the period from 2016 to 2018.

Measure the level of Leanness of specific company in the electronics industry
Langr, David ; Martínez, Felipe (advisor) ; Moravec, Stanislav (referee)
This thesis brings a view of the Leanness level of company based on ethnographic research. The combination of these two disciplines, the Lean concept and ethnography, is unique and brings new direction to research the level and approach of organizations to Lean philosophy. There is possible to assess the company in areas of value for customers, waste and continuous improvement through the research. Through the analysis, it is possible to find out where the organization has areas for improvement. The aim of the thesis is to propose the step to increase the level of Leanness of the organization. The thesis deals with the analysis and measurement of Leanness level of production and administrative processes in a manufacturing plant in the electronics industry.

Tests of Semiconductor Detectors for ATLAS Upgrade
Sýkora, Martin ; Kodyš, Peter (advisor) ; Mikeštíková, Marcela (referee)
This thesis is focused on beta source tests of prototypes of ITk Strip modules at IPNP in Prague in the framework of the ATLAS Upgrade project. New expe- rimental apparatus will allow comparison of beta source test results with other testing methods including laser or test beam. I participated in the assembly of the whole apparatus, script development for a number of automated measurements using specialized ITSDAQ software and ROOT. Finally, summary of obtained properties of tested end-cap R0 DAQload with mini sensor is provided based on beta source tests and characterization of the readout chip. The resulting collec- ted charge value corresponds to 3.1 fC and together with often referred quantity signal-to-noise ratio, which equals 35, it is one of the most important results of the thesis. The experimental arrangement including overall analysis of results will be usable for the future production phase of the project. 1

Tests of Semiconductor Detectors in Prague Laboratory
Sýkora, Martin ; Kodyš, Peter (advisor) ; Řezníček, Pavel (referee)
This thesis is focused on automatisation and synchronisation of newly installed devices in Prague laboratory. The devices will form an experimental arran- gement not only for laser tests of ITK modules for the ATLAS detector, but also for tests of other types of semiconductor detectors. In addition to ensuring of a central control of the devices the goal of the thesis was to understand the principle of particle detection in high energy physics as well as to get acquainted with the construction of pixel and microstrip detectors. I participated in the development of a script for cont- rolling a laser, 3-axis motorised translation stages, an optical attenuator and a pulse generator via RS-232 and GPIB communication interfaces from an object-oriented program ROOT. Finally, all installed devices were put into operation and a detailed description of their bundled software and internal control commands was included. The apparatus will participate during upcoming years in the research of the new generation of ITK modules for ATLAS upgrade.

Electronic kits in physics education
Hnyk, Michal ; Žilavý, Peter (advisor) ; Dvořák, Leoš (referee)
Title: Electronic kits in physics education Author: Michal Hnyk Department: Department of physics education Supervisor: RNDr. Peter Žilavý, Ph.D., Department of physics education Abstract: This diploma thesis named Electronic kits in physics education contains five main parts. It deals with the use of electronic kits in the physics education and references a research of literature discussing this problem in the first part. Thesis offers a brief overview of types of electronic kits, which are being used in education in schools of the Czech republic in the second part. The third fundamental part then describes the design of the prototype of kit suitable for education and documents the construction including the experience, which author acquired during the work, and technological processes. Fourth part of the work documents the piloting of the kit. The Builder's guide, which is a part of the kit and serves as a source of knowledge and suggestions for the user, is presented in the last part. Keywords: electronics, kit, education

The Evolution of the Global Microchip Market
Srba, Lukáš Martin ; Bolotov, Ilya (advisor) ; Čajka, Radek (referee)
This thesis aims to explain the evolution and transformation of the microchip industry. It focuses on the changes and prediction of the future state including its causes and consequences. The analysis starts on the general description of the market and continues through its subjects ending on relationships between them. This serves as a source of information to the prediction in the final part of the thesis. In the beginning the products, which are taken into consideration in this work (namely CPUs, GPUs and APUs), are described. Following this, there is an analysis of the competition environment that defines a structure of the market upon which further work is based. (Three levels; the manufacturer of photolithographic machines, makers of the chips and their designers and OEM and aftermarket subjects.) The penultimate part defines the barriers to entry to this market and three categories are drawn up: economic, technical and geoeconomic, which are applied to every level of the market. Thus all prerequisites to a successful prediction are satisfied. In the last part of the thesis the prognosis is made and defined, along with its assumptions and limitations. In the concluding part of this work the consequences and results are summarized.
