Charge Exchange processes involved in projectile-target interaction at low energy range studied by HS-LEIS
Bábík, Pavel ; Král, Jaroslav (referee) ; Průša, Stanislav (advisor)
This diploma thesis is focused on the charge exchange processes between projectile and target studied by the Low Energy Ion Scattering (LEIS) technique. Basic premise to investigate charge exchange processes is correct cleaning processes and proper settings of experimental instrument Qtac 100 placed in the Central European Institute of Technology (CEITEC) in Brno. Ion fraction expresses neutralization rate of the projectile. The parametr is investigated for clean and oxidized polycrystalline copper. Oxygen presence performs a significant part of reionization of backscattered neutralized projectiles.

Analysis of Nanostructures by ToF-LEIS
Duda, Radek ; Král, Jaroslav (referee) ; Mašek, Karel (referee) ; Dub, Petr (advisor)
The presented thesis deals with the utilization of TOF-LEIS analytical method in the area of nanostructure analysis. A new procedure for depth profiling of the elemental composition of the sample, based on the alternate measurement with the DSIMS method, was established. The TOF-LEIS method is able to detect the interface between the layers before its mixing by the ion beam of the DSIMS method. Furthermore, a procedure of TOF-LEIS spektra modification was established to obtain the actual concentration of elements in the sample by reduction of a multiple collision contribution. By comparison of TOF-LEIS spectra with the results received by the DSIMS method the ratio of molybdenum and silicon ion yields was obtained. In the next section advantages of the TOF-LEIS method in combination with XPS during analysis of thermal stability of gold nanoparticles are presented. The mutual complementarity of both methods is shown and final conclusions are supported by electron microscopy images. The final section deals with a newly assembled apparatus for the TOF-SARS analytical method and shows its possibilities regarding the detection of hydrogen on the graphene.

Complex ion beam based depth profiling of anticorrosive layers
Holeňák, Radek ; Král, Jaroslav (referee) ; Bábor, Petr (advisor)
Předložená diplomová práce se zabývá implementací metody rentgenové emisne indukované částicemi do experimentálního uspořádání za účelem doplnění rodiny metod založených na iontových technikách, tj. Rutherfordovy zpětné rozptylové spektrometrie, spektrometrie elastického zpětného rozptylu a analýzy detekce doby letu/energie elastického odrazu. Výhoda více-metodického přístupu je demonstrována na vrstvách ze slitin přechodných kovů obsahujících lehké prvky, kde samo-konzistentní analýza poskytuje výrazně zlepšené a přesné informace o stechiometrii, hloubkovém rozložení a tloušťce slitiny. Hmotnostní spektrometrie sekundárních iontů je použita pro porovnání a doplnění získaných výsledků.

The standard SOAP and its applications in small and middle enterprises.
Lupták, Boris ; Král, Jaroslav (advisor) ; Bulej, Lubomír (referee)
SOAP standard is core protocol used in web services. Web services open new possibilities in application interaction over the network. In connection with web services there has been much discussion of service oriented architecture. The main goal of this thesis is to show possibilities of SOAP in the context of small and medium businesses. To achieve this goal SOAP and accompanying nonns are described as well as the mechanism through which SOAP can be and is extended. Several standard extensions are shown. Furthennore this thesis points out the pros and cons of such usage as well as similar alternative approaches. The usage of SOAP is docmnented on several real life exainples. Part of this thesis concerns with fundamental principles of service oriented architecture and the connection between web services and service oriented architecture. The need of web services alignment with business processes and coarse grained interfaces are discussed as well. Powered by TCPDF (www.tcpdf.org)

Bussiness intelligence means in modern information systems
Vojtek, Martin ; Král, Jaroslav (advisor) ; Richta, Karel (referee)
Business intelligence (BI) is the ability to find and understand complex relations in business, to effectively adapt to changes of environment (competition, market, trends), to learn from data. Integration of BI applications with existing enterprise information systems leads to complex process. This process can comprise information, process, portal and service oriented integration. For this type of integration, it is also possible to use ESB technology. When integrating such complex systems, usage of standards gains great importance and significantly contributes to the architecture of result solution. Implementation of integration of BI applications with enterprise information systems represents the EPA application, which is built on Java EE integration platform with usage of JBosss, open source application server, Oracle database, data mining tools and ETL. Data warehouse implemented on the top of Oracle database is used for the integration of data sources. Part of the application presenting graphs and interactive cross tables is built on JBoss Seam, modern integration framework, which integrates technologies like JBoss Rules, JSF, EJB3 and jBPM.

Factors influencing customer profitability: an empirical examination in noncontractual settings
Hanuska, Norbert ; Kyjonka, Vladimír (advisor) ; Král, Jaroslav (referee)
Understanding of how to manage relationships with customers has become an important topic for both academic and practitioners in recent years. The effectiveness of business can be greatly improved by identifying the drivers of the most profitable customers and using them to target the right customers. In this study we identify exchange characteristics such as amount of money spent per purchase, customer relationship duration with firm, ratio of cross-buying and demographic characteristics such as age and gender as important drivers of the most profitable customers. The results of the study have important implications for academicians in understanding what drives the most profitable customers in noncotractual settings as well as practitioners to help design more effective marketing strategies. Moreover, the results of knowledge discovery about customers by different data mining techniques also contribute to help researchers identifying feasibility of these methods.

Tools for experiments with grammar and languages
Krejsa, Jiří ; Bednárek, David (advisor) ; Král, Jaroslav (referee)
The main goal of the thesis is the design and implementation environment that provides tools for working with grammars and languages. The environment is implemented by the library to which the user is working through the API. The library enables manipulation with languages represented as grammars or automata, transfer language between its various representations and to test whether the grammar is regular, linear or LR(k). The library found counterexamples in case that condition is violated. The thesis also highlights the future library expansion. Part of this work is a sample implementation of library usage. The library and samples are written in C++.
