1. Tire/road noise : Studies of the mechanisms of noise generation, methods of measurement and road surface characterization
Sammanfattning : .... LÄS MER
2. Development and Application of Reactor Noise Diagnostics
Sammanfattning : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

3. Noise from wind turbines
Sammanfattning : A rapid growth of installed wind power capacity is expectedin the next few years. However, the siting of wind turbines ona large scale raises concerns about their environmental impact,notably with respect to noise. LÄS MER
4. Classroom noise : exposure and subjective response among pupils
Sammanfattning : In Sweden, all children must have access to education of equal value and the curriculum points out the importance of a good environment for development and learning. Modern working methods differ a lot from the traditional. Teaching nowadays is focused on problem-solving. Students are more interactive, working in groups and projects. LÄS MER
5. Flow Pulsations in Fluid Power Machines - a Measurement and Simulation Study
Sammanfattning : Stricter requirements for better working environment involve noise and vibration control of hydraulic machines. The operational conditions for hydraulic machines, such as pressure and rotational speed, are also increasing and this makes it even more difficult to develop a quiet, vibration-free machine due to the interdependence between noise and escalating operational conditions.
