1. Hörselscreening av en population med utvecklingsstörning : Utvärdering av psykoakustisk testmetod och av OAE-registrering som komplementär metod
Sammanfattning : Populationer med utvecklingsstörning behöver kontinuerlig hörseltestning, men konsensus om lämplig testmetod saknas.Syfte: Syftet med Studie I var att utvärdera psykoakustisk testmetod och med Studie II att utvärdera OAE-registrering som komplementär metod.Studie I. LÄS MER
2. On the quantification of healing in asphalt materials
Sammanfattning : Asphalt materials exhibit self-healing characteristics. In order to evaluate the healing capabilities of these materials, numerous investigations are carried out by researchers. These investigations include various definitions of healing and mechanical test methods to quantify the extent of healing. LÄS MER
3. Numerical predictions of heat-transfer applied to electrical machines
Sammanfattning : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. LÄS MER
4. Modelling and control of turbulent and transitional flows
Sammanfattning : The dynamics of fluid motion can accurately be described by the Navier– Stokes equations. Manipulating these equations to reduce their complexity but preserving their main characteristics has always been a key research activity in the field of fluid mechanics. LÄS MER
5. Road surface characterization using near infrared spectroscopy
Sammanfattning : This thesis presents a technology and method for classifying and characterizing different road conditions such as dry asphalt and asphalt covered with water, ice and snow. The method uses light sources of different wavelengths to illuminate the road surface and a detector to measure the reflected light from the road surfaces, dependent on how the surface have absorbed, scattered and polarized the light it is possible to classify the road condition.
