Deployment of SOFA-HI applications on the nxtOSEK platform
Kaščák, Kamil ; Bureš, Tomáš (advisor) ; Pop, Tomáš (referee)
SOFA-HI is an extension of the SOFA 2 component system,which is developed at Department of distributed and dependable systems. SOFA-HI focuses on support for development of real-time embedded applications using component-based approach. This thesis extends existing SOFA-HI implementation with support for development and deployment of SOFA-HI application to nxtOSEK platform which is a small-footprint real-time operating system and board support package for LEGO Mindstorms NXT. In particular, existing tools for application development and deployment are extended to support nxtOSEK platform. The thesis further provides pre-made components to allow communication with standard NXT sensors and actuators. Powered by TCPDF (www.tcpdf.org)

Support for enterprise applications in SOFA 2
Blénessy, Tibor ; Bureš, Tomáš (advisor) ; Hnětynka, Petr (referee)
Title: Support for Enterprise Applications in SOFA 2 Author: Tibor Blénessy Department: Department of Distributed and Dependable Systems Supervisor of the master thesis: RNDr. Tomáš Bureš, Ph.D. Abstract: Industry standards defining various aspects of enterprise systems were developed in order to make development of such systems faster and to increase interoperability. For systems created with Java platform, these standards are contained under Java Enterprise Edition. SOFA 2 component system provides a solid base for development of ex- tensive component oriented systems. Goal of this work is to propose and empirically verify the possibility of integration of existing industry standards for enterprise applications in SOFA 2. Proposed solution extends SOFA 2 with components for web user in- terfaces based on Java Servlet API standard and with components for persisting data into relational databases based on Java Peristence API. In addition, it integrates core technologies from the Java Enterprise Edition platform, which should make integration of further standards easier. Keywords: enteprise applications, component system, SOFA 2, Java EE

Variability of Execution Environments for Component-based Systems
Malohlava, Michal ; Bureš, Tomáš (advisor) ; Racek, Stanislav (referee) ; Duchien, Laurence (referee)
Reuse is considered as one of the most crucial software engineering concerns. It allows for delivering software systems faster with less effort. Therefore, the thesis explores limits of reuse in the context of component systems. It analyzes in depth contemporary component systems, finds their commonalities and variation points, and introduces a meta-component system -- a software product line which allows for producing a tailored component system based on a set of requirements. The thesis addresses the meta-component system definition and focuses on its crucial aspects which play the key role in component systems preparation- (1) a configurable execution environment and (2) generation of implementation artifacts. To address the first aspect, the thesis proposes a model-driven method for creating configurable execution environments. Motivated by creating execution environments, the thesis contributes to (2) by introducing a notion of domain-specific languages interoperability in the context of the code generation. Furthermore, the thesis elaborates the proposed notion resulting into a family of interoperable domain-specific languages which is parametrized by a general purpose language.

L-systems online
Fišer, Marek ; Pelikán, Josef (advisor) ; Mráz, František (referee)
An L-system in its simplest form is a variant of a context-free grammar. Originally, L-systems were developed and are still mainly used for modeling plant growth, though with L-systems it is possible to create general fractals, models of towns or even music. However, anyone interested in L-systems and wanting to experiment with them may have difficulty finding an appropriate application. The goal of this work was to create an online system, suitable for a wide range of users, for working and experimenting with L-systems. The resulting solution consists of two parts. The first part is a universal, easily-expandable library for processing L-sys- tems. Expandability is achieved thanks to its modularity. All input is processed through interconnected components that are specialized in particular activities. The specialization of the components also contributes to the clarity and reliability of the whole processing system. The library is independent and multiplatform and can thus be readily used in other applications. The second part consists of a modern web interface designed to be under- standable for beginners and yet also capable of providing advanced features for more advanced users. Part of the site is a gallery of L-systems to which each user can contribute and which thus helps to create a user-community. The...

Component Interconnection Inference
Olšarová, Nela ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
The Master Thesis deals with the design of hardware component interconnection inference algorithm that is supposed to be used in the FPGA schema editor that was integrated into educational integrated development environment VLAM IDE. The aim of the algorithm is to support user by finding an optimal interconnection of two given components. The editor and the development environment are implemented as an Eclipse plugin using GMF framework. A brief description of this technologies and the embedded systems design are followed by the design of the inference algorithm. This problem is a topic of combinatorial optimization, related to the bipartite matching and assignment problem. After this, the implementation of the algorithm is described, followed by tests and a summary of achieved results.
