This work focuses on vector field visualization and approximation or interpolation. We summarize the knowledge about vector fields and its critical points as they are the most important property of all vector fields. Next, we present the interpolation and approximation techniques together&#x...

A surface reconstruction of large scattered datasets using interpolation or approximation methods is often a task in many engineering problems. Several techniques have been developed for the surface reconstruction, but they mostly require the conversion of a scattered dataset to ...

During recent years, neural networks show crucial improvement in catching semantics of words or sentences. They also show improves in Language modeling, which is crucial for many tasks among Natural Language Processing (NLP). One of the most used architectures of Artificia...

This text summarizes my work in the field of computer generated display holography. It tries to explain what motivated me to explore certain aspects of its fundamental principles and briefly explains the results. The reader interested in details finds them in my resear...

Wireless sensor networks gained a huge popularity in the last two decades. Espe- cially networks with mobile nodes are being intensively researched. This Ph.D. thesis concept addresses a special case of sparse and disconnected mobile wireless networks { opportunistic networks. T...

This paper describes an early version J-Serializer, a Java tool for serialization of concurrent programs written in the Java language. It shows some basic concepts it is based on as well as some details of internal functioning and the conversion process.

This paper describes a component decomposition of a CHAMP control system for flexible manufacturing. A new active database approach is introduced to simplify relations and messages within the system. The system is described in terms of SOFA software components and takes advantage...

This paper describes J-Sim v. 0.1.1, an object-oriented library using the method of pseudoparallel execution for simulation of discrete processes. Being written in Java, J-Sim is a fully portable successor to C-Sim, an already existing C-based library. The concepts used in both&#...

The paper provides an overview of current state of technology in the field of log file analysis and stands for basics of ongoing PhD thesis.The first part covers some fundamental theory and summarizes basic goals and techniques of log file analysis. It reveals that log&#...

Several approaches for software fault tolerance in component oriented systems have been proposed, with varying level of reliability. This paper gives a proposal to enhance SOFA framework with replication based fault tolerance. With added fault tolerance support, SOFA framework allows ...

This technical report report describes current stage of an experimental SOFA implementation created at the Department of Computer Scienence and Engineering, University of West Bohemia. The information hereafter is intended mainly for new SOFA team members and students of master degree ...

Text of the report presents an example technical report for KIV/DCSE. It does so by introducing two simple verses that can be used for filling in sample text in technical reports.

Software modules and components have always played a key role in software engineering, primarily as key abstractions that embody the principle of information hiding, using separation of interface and implementation. In most module- and component-based systems, the specification of the inter...

Many heuristic algorithms searching for triangulations by a given criterion exist. The main problem of these algorithms is that the found solution is only an approximation with some error. The size of the error cannot be known without exact solution, which can be found&...

This paper describes the developing and testing of a new method for processing and modeling implicitly defined objects. The base idea started from the popular system HyperFun. The HyperFun is a system, which develops at the University of Hosei. It is the system for ...

This paper presents state-machine approach that was used to create a discrete-time process-oriented simulation model based on the C-Sim simulation library. The method is demonstrated on a model of the Pilsen town traffic node, where we have a dynamic set of vehicles which are ...

The Delaunay triangulation is one of the most popular and most often used methods in problems related to the generation of meshes. A lot of the optimal properties of Delaunay triangulation are known in 2D, where it has been intensively studied during the last twenty years...

For twenty years, it has been clear that many datasets are excessively complex for applications such as real-time display, and that techniques for controlling the level of detail of models are crucial. Many applications in computer graphics and related fields can benefit from autom...
