21. Estimation of Thermal and Hydraulic Characteristics of Compact Brazed Plate Heat Exchangers
Sammanfattning : This thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. LÄS MER
22. Verification of dose calculations in radiotherapy
Sammanfattning : External radiotherapy is a common treatment technique for cancer. It has been shown that radiation therapy is a both clinically and economically effective treatment for many types of cancer, even though the equipment is expensive. The technology is in constant evolution and more and more sophisticated and complex techniques are introduced. LÄS MER
23. Compartment Fire Temperature Calculations and Measurements
Sammanfattning : This thesis is devoted to heat transfer and fire dynamics in enclosures. It consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy, fire dynamics and specific fire scenarios that have been studied. LÄS MER
24. Physics of Strong Correlations in Electronic Structure and Model Calculations
Sammanfattning : Using field theoretical methods models of strongly correlated electrons have been investigated. Application to electronic structure calculations has been made. LÄS MER
25. Materials Design from ab initio Calculations
Sammanfattning : This thesis presents a theoretical study of bulk materials using ab initio methods based on the density functional theory (DFT).Crystallographic structural phase transformations and phase stability for 5f-dioxides, ABO3 perovskites, and ABO4 compounds have been extensively studied.
