Addsessing On-Demand Assembly and Adaptation Using a Runtime Intentional Versioning Engine
Gergič, Jaroslav ; Tůma, Petr (advisor) ; Brada, Přemysl (referee) ; Bešta, Miloslav (referee)
The World Wide Web has been changing rapidly in the past few years due to the emergence and fast adoption of large variety of new internet-enabled devices: starting with web-enabled phones through converged appliances, combining a PDA and a cell phone, to specialized internet tablets and business productivity tools. This change is bringing many challenges into the process of designing and developing both the thin-client (web-based) and thick-client (device-hosted) applications and related services. The application and service providers are facing a trade-off between the number of platforms and devices they are able to support, representing the size of the potential market, and mounting costs tied to developing and supporting multiple variants of their applications. There are several ongoing efforts taking place at various standardization organizations and industry associations to address these issues. Some of the essential standards for specifying and transporting device capabilities have been available for several years now, but so far they have had only a limited impact on the way the actual applications and services are being designed and developed. This work is trying to identify and explain the shortcomings of the existing approaches and as a reaction proposes an application-centric framework designed...

Source Code Similarity Detection
Lano, Radek ; Tůma, Petr (advisor) ; Parízek, Pavel (referee)
The objective of this thesis is to design and implement a tool usable for detecting similar code in different projects. The tool should be able to locate code pasted from one project to another and should be able to cope with average attempts to thwart the detection such as symbol renaming, changing the order of unrelated entities, moving entities to different files, adding or removing comments, etc. The tool is implemented in language C++ and is ready to compare source files written in languages C and C++. The tool also enables the comparison of source code written in different languages, which can be compiled by the GNU C Compiler. To obtain good results in these cases, new modules should be added (this is necessitated due to different representations of the GNU C Compiler inner form for different languages). The first part of this thesis focuses on describing the problem domain, the architecture design and the tools usable for implementation. The second part centers on the implemented solution, a description of data structures and possibilities for application expansion using additional modules. The last part of the thesis sums up the results and outlines future possibilities of implementation.

Determination of proteinogenic amino acids by high-performance separation techniques
Hodek, Ondřej ; Křížek, Tomáš (advisor) ; Pacáková, Věra (referee) ; Tůma, Petr (referee)
(EN) Proteinogenic amino acids are key components of living organisms. Thus, the latest metabolomics research has focused on developing fast and sensitive methods for the determination of amino acids. In this context, this thesis contains two studies describing development of high-performance separation techniques for the quantification of amino acids. In the first study, a capillary electrophoresis method was developed for the determination of free amino acids in tobacco plants, particularly focusing on optimizing the extraction of amino acids from solid plant materials. The extraction procedure was optimized using design of experiments (DoE) to obtain the highest possible extraction yield of amino acids. Factors such as volume and concentration of the extraction solvent (hydrochloric acid) were assessed as the most significant. Subsequently, the optimal values of these factors were determined using response surface methodology (RSM). Lastly, proteinogenic amino acids were quantified using capillary electrophoresis with contactless conductivity detection and calibration with internal standard, which improved the precision of the method. The second study aimed at developing a supercritical fluid chromatography method for the determination of free proteinogenic amino acids in human plasma. The most...

Network Repository for Performance Evaluation Results
Ondroušek, Pavel ; Tůma, Petr (advisor) ; Kalibera, Tomáš (referee)
For performance evaluation of software systems, benchmarking is used. Benchmarking generates a large amount of output data, which is necessary to store, process and evaluate it. Network Repository serves as a repository of benchmark results. The goal of the master thesis is to design and implement the data storage with a support of various result types with the possibility of the format configuration. Stored results can be processed, evaluated, or used as a source for plotting. As part of the master thesis, the design and implementation of a general framework for benchmark storage and evaluation is developed and a sample configuration for the selected benchmark result data format is established.

Distribution for Open Modeling Interface and Environment
Čurn, Jan ; Tůma, Petr (advisor) ; Bureš, Tomáš (referee)
OpenMI is a standard used to link water and environmental models. However, the standard and the currently available supporting software only support single-computer single-threaded simulations. The thesis delivers a system capable of linking OpenMI models across computers using their network subsystem. The system consists of hub servers that provide access to models registered by clients. The clients make local models accessible to the servers and also provide the legacy OpenMI software with a transparent access to remote models registered by other clients.

Performance in Software Development Cycle: Regression Benchmarking
Kalibera, Tomáš ; Tůma, Petr (advisor) ; Hauswirth, Matthias (referee) ; Eeckhout, Lieven (referee)
The development cycle of large software is necessarily prone to introducing software errors that are hard to find and fix. Automated regular testing (regression testing) is a popular method used to reduce the cost of finding and fixing functionality errors, but it neglects software performance. The thesis focuses on performance errors, enabling automated detection of performance changes during software development (regression benchmarking). The key investigated problem is non-determinism in computer systems, which causes performance fluctuations. The problem is addressed by a novel benchmarking methodology based on statistical methods. The methodology is evaluated on a large open-source project Mono, detecting daily performance changes since August 2004, and on open-source CORBA implementations omniORB and TAO. The benchmark automation is a complex task in itself. As suggested by experience with compilation of weather forecast model Arpege/Aladin and implementation of component model SOFA, large systems place distinguishing demands on tasks such as automated compilation or execution. Complemented by experience from Mono benchmarking, the thesis proposes an architecture of a generic environment for automated regression benchmarking. The environment is being implemented by master students under supervision of...

Vojta, Jiří ; Coufal, Pavel (advisor) ; Tůma, Petr (referee) ; Jelínek, Ivan (referee)
(EN) In the first part of this work, analytical methods for determination of impurities of active pharmaceutical ingredients (API) in combined pharmaceutical dosage forms were developed and validated. Development of the methods covered both the optimization of sample preparation procedure and chromatographic conditions. The methods were validated according to International Conference on Harmonization guideline and both of them were confirmed to be able to analyze stability samples. Impurities in paracetamol, codeine phosphate hemihydrate and pitophenone hydrochloride in the presence of fourth API fenpiverinium bromide were separated by using ion-pair reversed phase chromatography with gradient elution. Symmetry C18, 250 x 4,6 mm, 5 µm heated to 35 řC was used as a separation column. A diode array detector was used. The detection wavelengths were set as follows: 220 nm for paracetamol impurity K, 245 nm for paracetamol and its other impurities and 285 nm for codeine, pitophenone and their impurities. Impurities in valsartan, amlodipine besylate and hydrochlorothiazide were separated by reversed phase UHPLC method with gradient elution. Chromatographic column Zorbax Eclipse C8 RRHD, 100 x 3,0 mm, 1,8 µm heated to 30 řC and spectrophotometric detection were used. The detection wavelengths were set as...

Linux kernel userspace modules
Lipavský, Lukáš ; Děcký, Martin (advisor) ; Tůma, Petr (referee)
This thesis proposes and implements a new method of implementing Linux kernel drivers in userspace applications - userspace drivers. Instead of proposing fixed interface for accessing kernel functionality from userspace application and using dedicated kernel module to implement functionality not accessible via the interface, proposed method allows applications to define custom interfaces to the kernel. The interface is defined in special bytecode that is loaded into the kernel. The bytecode also provides functions that can be called from the kernel and that work even in atomic context (interrupt handlers, etc.). The bytecode is architecture and kernel configuration independent. The proposed method makes it possible to develop kernel drivers implemented in userspace applications without the need of dedicated kernel module.
