16. Energy Usage in Supermarkets - Modelling and Field Measurements
Sammanfattning : This thesis investigates a special type of energy system, namely energy use in supermarkets through modelling, simulations and field studies. A user-friendly computer program, CyberMart, which calculates the total energy performance of a supermarket, is presented. LÄS MER
17. Adding usability : Methods for modelling, user interface design and evaluation
Sammanfattning : Many system development projects fail to provide information systems with high usability. This thesis focuses on how to solve this problem by introducing methods for modelling, user interface design and evaluation. These methods are primarily designed to serve as complements to existing methods for systems development. LÄS MER
18. Modelling and simulation of turbulence subject to system rotation
Sammanfattning : Simulation and modelling of turbulent flows under influence of streamline curvature and system rotation have been considered. Direct numerical simulations have been performed for fully developed rotating turbulent channel flow using a pseudo-spectral code. The rotation numbers considered are larger than unity. LÄS MER
19. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications
Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER
20. Towards a learning system for process and energy industry : Enabling optimal control, diagnostics and decision support
Sammanfattning : Driven by intense competition, increasing operational cost and strict environmental regulations, the modern process and energy industry needs to find the best possible way to adapt to maintain profitability. Optimization of control and operation of the industrial systems is essential to satisfy the contradicting objectives of improving product quality and process efficiency while reducing production cost and plant downtime.
