The subject of this research is to investigate the possibilities for reducing the level of noise in the travel area of railway vehicles which is produced from the most dominant source – the swivel base in contact point with rail. Produced noise is presented inside of the passenger compartment and with this research it is made a step tow...

 During the development and exploitation of various technical systems, often encounter the need to we need the data pertaining to predict how these systems behave during their exploitation. This primarily relates to their technical qualities such as reliability indicators (reliability, availability, mean time between failures, failure intensit...

 This paper treats a priori (the reason why) ecological heating systems using boilers with complete combustion, with the main objective function of significant material cost savings and increase the level of effectiveness of the system. Burning modulated and cheapest biomass-wood bark (encrustation), and other wood waste which are directly wit...

 This paper describes the Box and Gaussian model as two of the simplest Euler models for the distribution of air pollutants in the environment. These models are based on the simplicity and they are easily applied mathematical, as well as implemented in computer programs, which greatly simplifies the calculations distribution of air pollution i...

 This paper experimentally demonstrates automatic forming of the 3D models which are convenient for further analytics from paper documentation. The classic 3D models are very convenient for simple visualisation, but this is where their practical implementation ends. The collection of data is different from the actual "brute force" way, it was ...

 In this paper we examine the system reliability and quality in the provision of services in telecommunications, with particular emphasis on SLA Service-level agreements. It is an agreement between two or more parties on the level, quality and responsibilities in the provision of services. It is necessary to define the service that is provided...

 Energy harvesting is rapidly expanding into new applications. The idea of micro-scale energy harvesting, and collecting miniscule amounts of ambient energy to power electronic systems, was still visionary and limited to research proposals and laboratory experiments Ultra-low-power technology is enabling a wide range of new applications that h...

Public administration institutions focus on constant implementation of new technologies trough separated ICT projects. In most cases, these projects consider simple implementation of ICT technology on current business process without consideration if these processes needs modification in order to accept new technology. Because of this, result might...
