Simulation of water supply networks using modern means of information technology

We present in turn the development of computer technology from the beginning of its creation on our planet. Then we discuss the development of information technology at our university. At the end, we present a selected technical problem which is the task of simulation of the water supply network. We present mathematical models of these issues and algorithms for their solutions requiring the use of a computer

Green computing and energy storage systems

Because of growing amount of the data(known as „big data”) needed to be store and process there is a rapid growth of usage electricity and emission. In this paper we present the IT solution of this problem: green computing, solutions to storage and manage the energy and IT support needed to manage and control those systems. The article presents the main idea and already implemented solutions

Patient with constrictive pericarditis

Constrictive pericarditis is a rare pericardial disease in which the pericardial sac is losing its elasticity, cardiac filling becomes impaired by the stiffness of pericardial walls. We discuss patient management

Sustainable Services to Enhance Flexibility in the Upcoming Smart Grids

Global efforts are already focusing on future targets for even more increases in renewable energy sources contribution, greater efficiency improvements and further greenhouse gas emission reductions. With the fast-paced changing technologies in the context of sustainable development, new approaches and concepts are needed to cope with the variability and uncertainty affecting generation, transmission and load demand. The main challenge remains in developing technologies that can efficiently make use of the available renewable resources. Alternatives in the form of microgrids or virtual power plants along with electricity storage are potential candidates for enhancing flexibility. However, intelligence must be added at all levels in the grid and among all the equipment comprising each subsystem, in order to achieve two-way communications and bidirectional flow of power. Then, the concept of smart grid can be realized and, relying upon software systems, it can remotely and automatically dispatch and optimize generation or storage resources in a single, secure and Web-connected way. Deploying smart configurations and metering promises new possibilities for self-managed energy consumption, improved energy efficiency among final consumers and transition to more consumer-centric energy systems via demand response and demand-side management mechanisms
