Opis:
Information and communication technologies have undergone substantial development in recent decades. These changes have been manifested not only in the economy, but also in people’s everyday life, as modern technologies have fundamentally transformed working methods, leisure activities, and administrative processes. The strong influence of advanced trends has also left changes in public administration. The international concept of eGovernment has come to the fore, known in Slovakia due to the development of the Internet public services under the “informatization” of public administration. In Slovakia, as well as throughout the world, the primary objective of electronification is to increase the obligations of the state administration, reduce corruption, improve communication within the public administration itself, increase transparency, save finances, eliminate empty bureaucracy, and simplify the contact of citizens with the authorities. eGovernment allows individual states a range of options for delivering public services electronically, such as interactive collaboration or providing information online. In spite of all the advantages brought by information and communication technologies, the Slovak Republic still lags behind in the implementation of computerization in public administration. In the field of electronic public administration, individual processes are constantly influenced primarily by external changes (political), but also by internal changes (organizational). These are precisely the types of changes that can be described as limiting factors for the development of eGovernment. The objective of the present paper is to analyze how public policy actors in three studied countries influence the development and implementation of electronic public administration. The analysis will then culminate in the proposal of appropriate solutions to remove the identified barriers for the conditions of the Slovak Republic.

Opis:
This paper is focused on the theoretical study of heat conduction in the multi-brake system of the automated guided vehicle (AGV). The study aims to compare the amount of heat generated during braking from 10 m/s until a stop in a brake system based on organic and ceramic friction material. The theoretical study of heat conduction is solved in Matlab computational software using a derived Fourier partial differential equation for nonstationary heat conduction. The results of the simulation of the heat conduction are shown in the diagrams and indicate not only the temperature dependence in the period during braking from a speed of 10 m/s to a stop but also the amount of heat accumulated in the steel disc during braking. The simulation results show that braking in both brake systems generates approximately the same amount of heat. The difference occurs in the period of thermal activity, which was influenced by the length of the braking distance. This is caused by a coefficient of friction that significantly affects the final braking result. Finally, it can be stated that the brake system based on organic material must be equipped with a steel disc with a minimum thickness of 8 mm. This is because the brake system based on organic friction material has a set temperature limit of 160 degrees Celsius. The results presented in this study will help an engineer constructor to choose the right procedures and parameters of geometry for designing the mentioned braking system for the considered AGV.
