1. 16. Thermal response test : numerical simulations and analyses

   Författare :Anna-Maria Gustafsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

   Sammanfattning : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. LÄS MER

3. 17. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

   Författare :Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

   Sammanfattning : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

4. 18. Dynamic response reconstruction using passive components

   Författare :Anders Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

   Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER

5. 19. Real-Time Communication over Switched Ethernet with Resource Reservation

   Författare :Mohammad Ashjaei; Thomas Nolte; Moris Behnam; Luis Almeida; Thilo Sauter; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time communication; Response time analysis; Computer Science; datavetenskap;

   Sammanfattning : Due to the need for advanced computer-controlled functionality in distributed embedded systems the requirements on network communication are becoming overly intricate. This dissertation targets the requirements that are concerned with real-time guarantees, run-time adaptation, resource utilization and flexibility during the development. LÄS MER

7. 20. Quantitative analysis of tumor growth and response to therapy

   Författare :Esmaeil Mehrara; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tumor; growth; response; therapy; modeling; clinical;

   Sammanfattning : Modeling the natural growth of tumors is of value for evaluation of tumor progression and optimization of treatment strategies. However, modeling tumor growth based on clinical data is hampered by the limited data available, since therapy is in general initiated as early as possible after diagnosis. LÄS MER
