Document similarity measurement techniques overview

Author(s): Vladimír HANUŠNIAK

Abstract:
Examine data for similar items is one of the fundamental data-mining problem. Application of methods for similarity search could be useful for plagiarism or near-duplicate web page detection. The basis to measure similarity are distance measurement methods. The paper describes several distance measure methods and document representation suitable for document similarity analysis. Conclusion of the paper state the recommendation to measure document similarity.

Advanced technology possibilities of 3D scanning

Author(s): Pavol KUDELA

Abstract:
The object digitalization creation or more precisely relevant areas, pass through progressive periods, and the technological equipment development is rapidly progressing. Nowadays, we have the possibility to use devices that can scan small products in detail. These products are usually of various and hardly accessible sizes. This form of digitalization is used as a base for modelling or so-called post processing. The advantage is mainly the shortened period, the possibility of further model configuration etc. The article presents one particular technology and various others that are disposable and their reciprocal potential will be a contribution not only for the research purposes, but also to for practical purposes.

Different ways of system integration

Author(s): Michal JOŠTIAK, Michal ZÁBOVSKÝ, Boris BUČKO

Abstract:
Digitizing of knowledge of mankind and his activities leads to a massive increase of the recorded data. Rapid technological development of storage media leads into inexpensive data storage. It is obvious that currently we are storing any information without the need for an analysis of its importance. In many areas of science and research is need to store every generated information; in advance it is not possible to determine the significance of potential information. With this amount of data it is increasing demand for their efficient processing. This paper deals with different ways of system integration, from data level to UI level. In the conclusion we propose a new way to data integration – ontology.

Laser radar – LIDAR utilization for 3D data acquisition

Author(s): Pavol BUKOVAN, Pavol KUDELA

Abstract:
This article aims at 3D data acquisition by scanning. It describes a device located in a unique workplace of the University of Zilina – University Science Park. It is a mobile laser LIDAR designed for 3D data acquisition. First part of the article reveals information about the history of LIDAR device utilization, as well as its first commercial use. Nowadays, there are many kinds of LIDAR on the market, depending on a type. The potential of the equipment is mainly in its very precise output that can be used in different branches. Transport is certainly one of the most interesting ones, but also terrain surfaces mapping both inside and outside municipalities. That is why its utility potential is huge in these areas.

Progressive materials and technologies

Author(s): Barbora LUHOVÁ

Abstract:
In modern materials science the main trends are represented by fabrication, characterization and application of materials and structures with dimensions in or near the nanometer range. In this frame, inorganic nanomaterials have been increasingly attracting the attention of scientists owing to their interesting electronic, optical, magnetic, thermal, mechanical and chemical properties, which are highly dependent on their size and shape. Such geometry-dependent characteristics are essential for their high impact on fundamental aspects as well as for the high potential in technology applications.

Advanced technology possibilities of 3D scanning

Author(s): Andrej ČERŇAVA, Pavol KUDELA

Abstract:
The perspective of using modern technologies in production processes is more and more promoted in 3D scanning technologies. These technologies are mostly used to control products, reverse engineering, control of quality etc. Therefore, this paper describes 3D laser scanners that are located in University Science Park of the University of Zilina. Laser 3D scanners are now considered to be the most accurate devices due to product verification and prediction of adverse effects. In this paper, possibilities of digitalization by the 3D laser scanners will be described.

Specialized simulator oriented towards road traffic cargo vehicles

Author(s): Daniel BEŇADIK, Pavol KUDELA

Abstract:
This article is focused on USP UNIZA technological equipment. Treating the specialized simulator oriented towards road traffic cargo vehicles, suitable for research with full featured output in frame of examination of loaded material conduct as well as recreation periods of the user in given critical driving conditions. Simulation is a powerful tool for analysis, design and operation of complicated systems. Simulation provides ideal mechanism for research examination, unable to implement, too expensive or dangerous in real world, including the cognitive or physical abilities consideration, acquired knowledge concerning the drivers´ behavior, vehicles construction testing in virtual testing road and the drivers´ training.
