1. Dryout and Power Distribution Effects in Boiling Water Reactors
Sammanfattning : Film flow measurements at several axial positions in round pipes with variousaxial power distributions are presented for conditions corresponding to normaloperation of a BWR. It is confirmed that the film flow rate approaches zero atthe onset of dryout. LÄS MER
2. On drops and turbulence in nuclear fuel assemblies of Boiling Water Reactors
Sammanfattning : The study aims to develop the understanding of the mechanistic-type approach to quantify drop deposition in nuclear fuel assemblies of Boiling Water Reactors. This includes the effect of spacers. LÄS MER
3. Estimation of synchronization parameters
Sammanfattning : This thesis deals with the estimation of synchronization parameters in {Orthogonal Frequency Division Multiplexing} (OFDM) communication systems and in active ultrasonic measuring systems. Estimation methods for the timing and frequency offset and for the attenuation taps of the frequency selective channel are presented and investigated. LÄS MER
4. On 60GHz Wireless Communication Systems
Sammanfattning : The consumer of the telecommunication services of tomorrow will expectto receive the same services in a wireless fashion as he today receivesfrom a fixed network. These services require reliable high data rate. LÄS MER
5. Experimental Study and Modelling of Spacer Grid Influence on Flow in Nuclear Fuel Assemblies
Sammanfattning : The work is focused on experimental study and modelling of spacer grid influence on single- and two-phase flow. In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated. A special pressure measuring technique was used to measure pressure distribution inside the spacer. LÄS MER
