1. Low Frequency Impact Sound in Timber Buildings : Simulations and Measurements
Sammanfattning : An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. LÄS MER
2. High Frequency Tyre Vibrations
Sammanfattning : High frequency (above 1 kHz) noise generation from the tyre/road interaction is still not fully understood and accurately modelled.Two noise generation mechanisms previously suggested in the literature are reviewed: air pumping and noise generation cased by adhesive effects between the tyre tread and road surface.

3. Difficulties to Read and Write Under Lateral Vibration Exposure : Contextual Studies Of Train Passengers Ride Comfort
Sammanfattning : Many people use the train both as a daily means of transport as well as a working place to carry out activities such as reading or writing. There are, however, several important factors in this environment that will hamper good performance of such activities. LÄS MER
4. Terahertz radiation as a pump and probe for studying low frequency vibrations in proteins
Sammanfattning : Many functionally important structural changes in proteins proceed along the direction of their lowest frequency vibrations. These vibrations correspond to picosecond collective dynamics. Establishing the fundamental relationship between these vibrations and protein function remains a challenge within biophysics. LÄS MER
5. Vibration of Low-Frequency Floors - Dynamic Forces and Response Prediction
Sammanfattning : This thesis deals with methods for predictive calculations of the vibration response of low-frequency floors, i.e. floors with the lowest natural frequency below 7 to 8 Hz, subjected to pedestrian traffic and other dynamic forces. LÄS MER
