A Pécsi Tudományegyetem informatikai fejlesztésének története

A számítástechnika alkalmazása a pécsi felsőoktatásban 1971-ben kezdődött a Pollack Mihály Műszaki Főiskolán, egy évvel később a Jogtudományi Karon, majd a Pécsi Orvostudományi Egyetemen. A Pécsi Tanárképző Főiskolán az 1980-as évek elején jelentek meg az első számítógépek. Mivel korábban az egyetemi karok többsége önálló intézmény volt, az informatika fejlődésének története mindegyik karnál máskor, másképp indult és más pályát követett. A kötet célja, hogy betekintést adjunk egyetemünk informatikai fejlődésébe, amely a mai napig hatással van az oktatásra és a kutatásra egyaránt

Energetic model of an elementary pipe-segment of a steam-water network

The aim of the research is to develop a computer-based decision-supporting control system for a regional steam-water network in order to decrease the energy loss. In the starting phase of the applied research several investigations is needed about the two-phase flow and phase changing. This a priori information has to be collected in various circumstances, for example changing energy consumption and distribution. Furthermore, info-communication technology is required to manage the collecting of operational data and performing the identification of the energy network. In this article an a-priori data collection and an introductory model with numerical simulation is discussed

Energetic model for an elementary unit of a steam network

The main aim of the applied research work is the comprehensive examination of the elementary units of a regional energy-flow network (a steam network for providing steam energy for various industrial units from secondary steam of a power plant) in order to fulfill the consumers' energy requirements for heating and technological purposes. Further goal is the determination of the mass-flow and temperature distributions and the hydro-dynamical and thermal analysis of the elements of the network, which are connected to each other and to the environment by means of heat transfer. After this phase, in view of models of the elementary units, the conservation equations of the whole network have to be posed. The aim of the subsequent synthesis-tasks is to ensure the proper distribution of steam-energy according to the technological and economical demands of the consumers. This model-simulation activity, assuming varying energy distribution and energy consumption conditions, examines the possibilities of control and intervention of the operation with the aid of an info-communication technology installed on the network. Thus the simulation is the preliminary step for the establishment of a decision-supporting expert system
