1. Analysis of Industrial Microwave Ovens
Sammanfattning : This thesis deals with the analysis and design of microwave ovens used in the food industry. Such analysis is desirable in order to optimize the performance of the ovens and to reduce the time and expenses of developing new or improved ovens. LÄS MER
2. Behaviour and stability of shallow underground constructions
Sammanfattning : The growing needs of urbanization, like more transport possibilities, sewers, maintenance tunnels, the need of constructing shallow tunnels increase. By a better understanding of the mechanical properties and state of stress in the shallow parts of the bedrock it may be possible to determine which factors that are of importance at a specific construction site, and thereby increase the cost efficiency of pre-investigations and the tunnel construction.

3. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity
Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER
4. Development of the Wind and Air Temperature Sensor of the ExoMars 2022 HABIT Instrument
Sammanfattning : This work presents the development, validation and calibration of the air temperature sensors (ATS) and the air and wind retrieval method of the HABIT (HabitAbility: Brines, Irradiation and Temperature) instrument. HABIT is one of the two European payloads of the ESA/Roscosmos ExoMars 2022 mission that will land at Oxia Planum (18.20° N, 335. LÄS MER
5. The Applicability of Geoelectrical Methods in Pre-Investigation for Construction in Rock
Sammanfattning : Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. LÄS MER
