1. Investigation of Tonal Noise Sources from Centrifugal Fan using Detached Eddy Simulation
Sammanfattning : Since we spend the majority of our time indoors, heating, ventilation, and air conditioning (HVAC) systems have become a more and more important part of many people´s life. They provide a sufficient amount of airflow with the correct temperature, quality, and humidity. LÄS MER
2. Numerical investigation of tonal noise sources from centrifugal fan
Sammanfattning : Heating, ventilating, and air conditioning systems (HVAC) are today an important part of many people's life. They provide a sufficient amount of airflow with the correct temperature, quality, and humidity. The negative side is the noise it produces. Many improvements have been made in building development to reduce noise from the environment. LÄS MER
3. Mobile Satellite Broadcast and Multichannel Communications : analysis and design
Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER
