Global navigation satellite systems (GNSS), along with geographic information systems (GIS), are currently one of the most growing geo-information technologies. However, there is very little of projects which use mutual support of these technologies. The projects are mainly aimed at solving particular problems (signal propagation in a given area, coverage of GNSS signal, solutions of influence of barriers on the accuracy of measurement, etc.). This paper describes a global view on the interaction GNSS and GIS from standpoint of planning of measurement. The main benefit of GIS technology with support of spatial analyses consists in simulating the real environment and determining of effective deployment of GNSS methods in this locality. GIS thus partially replaces a reconnaissance of the terrain and it allows increasing the entire measurement process about a hierarchical level above, that is, into field of planning and management. The essence of method is the division of the area into subareas according to the conditions for GNSS measurements, and an optimal surveying method is assigned for each area. The paper describes a mathematical model and technique of implementation of the method into ArcGIS environment. Fuzzy logic is used due to the uncertainty of the conditions for the deployment of GNSS methods. The project also includes an expert system in which existing experience with GNSS measurements are stored. It is assumed that this expert system will be continuously updated and it will contribute to a gradual increase in the quality of the whole planning process. The proposed system is described by a form of block scheme and by a form of the state diagram in UML. © 2014 WIT Press.

The design of man-machine interface for devices that determine possible positions using Global Navigation Satellite Systems (GNSS) is the topic of this paper. The aim of this work is to simplify the existing complicated mechanism of setting of these devices and to allow their full utilization for naive users as well. The mathematical model of surveying process was developed using fuzzy logic within an analysis. The design of interface is based on the theory of state machine with hierarchical states. The proposal is implemented by a system topdown analysis and links between the functional sub-components are described using a sequential scheme. The communication of the user with interface is expressed a hierarchical state machine in UML 2.0. The core of solution is an expert system which is based on geographic information system (GIS) that simulates the measurement conditions in the given locality. The design of interface will be verified on the specific GNSS device, GRS-1 by Topcon Company. © 2014 American Scientific Publishers All rights reserved.

The article deals with the negative consequences of the Bologna process in practice. There is a mathematical model of education introduced. The theoretical model program is to demonstrate how the system of university education has changed after the introduction of the Bologna process. Also the causes of the decline of university education are discussed and measures to improve the situation are proposed. The findings are presented on the basis of the experience of the author and supported by research in the Czech Republic (CR) during the period of fifteen years from the Bologna process. The main cause of the negative consequences of this process include: commercialization of university education, the introduction of credit system without any continuity to the previous content of the curriculum three-tier system of studies (bachelor, master and doctoral). Finally, this paper includes recommendations for improving the current state of education. © 2015 Taylor & Francis Group, London.

The 3D MEMS optical switches are able to build dynamically reconfigurable, highly-scalable physical layer and to provide a required growing network bandwidth and agility for various service providers, datacenters, cloud computing networks, etc. The switch utilizes highly reflective miniature mirrors to manipulate an optical signal inside the switch directly without any conversions. Nevertheless, as indicated by the simulation results of this paper, many of developed mirrors are not optimized in the sense of dynamic behavior well. The coupling nature of mirror rotation makes its control difficult. In this paper, we present a simple optimization technique leading to decoupled rotation of the mirror about two perpendicular axes. © 2015 IEEE.

The 3D MEMS optical switch utilizes highly reflective micromirrors to manipulate an optical signal inside the switch directly without any conversions, offering bit rate and data protocol independency. As indicated by the simulation results of this paper, many of developed micromirrors (by various companies) are not optimized well in the sense of dynamic behavior and can be further improved. This non-optimal design negatively limits the switching speed of the optical switch. The switching mechanism is in a fact the two-way coupling between the mechanical structure (micromirror) and electrostatic field (electrodes) - see e.g. Ananthasuresh [1, Sec. 11.4]. This introduces additional effects resulting in coupled rotation of the micromirror about its axes - the cross-axis coupling effect. Existing solutions are mainly focused on the optimization of the control strategy of the micromirror aiming to suppress its oscillations and to minimize the switching time. Our approach is foremost focused on the optimization of dynamic characteristics of the micromirror. This suppress negative effects of cross-axis coupling and thus allows further reduction of the switching time of the switch. Our results are supported by simulation experiments, which consider the switching element as multiphysics system described by partial differential equations. © 2016 Elsevier B.V.

Material requirements planning (MRP) is a production planning and inventory management system used to manage logistics processes and designed to assist production managers in scheduling and placing orders for items of dependent demand. If it is implemented and used properly, it can be helpful for production managers to plan capacity needs and allocate production time. The article provides characteristics of the mentioned method; it describes the possible areas of application in manufacturing, purchasing and delivering activities. The paper considers the analysis of the production logistics in the chosen industrial company, focusing on information MRP system and the bottlenecks in the production.

This chapter is an attempt to attain a new and profound model of the nature's structure using a vortex-ring-fractal theory (VRFT). Scientists have been trying to explain some phenomena in Nature that have not been explained so far. The aim of this paper is the vortex-ring-fractal modeling of elements in the Mendeleev's periodic table, which is not in contradiction to the known laws of nature. We would like to find some acceptable structure model of the hydrogen as a vortex-fractal-coil structure of the proton and a vortex-fractal-ring structure of the electron. It is known that planetary model of the hydrogen atom is not right, the classical quantum model is too abstract. Our imagination is that the hydrogen is a levitation system of the proton and the electron. Structures of helium, oxygen, and carbon atoms and a hydrogen molecule are presented too. © 2010 American Institute of Physics.

The aim of this paper is the vortex-ring-fractal modeling of the hydrogen atom, which is not in contradiction to the known laws of nature. We would like to find some acceptable quantum model of the hydrogen atom as levitating model with a ring structure of the proton and a ring structure of the electron. It is known that planetary model of hydrogen is not right. The quantum model is too abstract. Our imagination is that the hydrogen atom is a levitation system of the ring proton and the ring electron.

This paper focuses on the fundamental aspects of the small series printed-circuit board (PCB) manufacturing process related to the space electronics flight hardware. The main emphasis is laid especially on presenting the selected own in-house expert solutions that have been proposed and finally implemented to resolve all the specific technological problems. The space electronics PCB production where manual soldering is applied can be considered as an exemplary technological area where correct and precise implementation of the specific PCB assembly procedures conforming to the ESA approved standards, called ECSS-Q-ST-xx, is the key important issue. © 2011 IEEE.
