1. 21. Well Testing, Methods and Applicability

   Författare :Jan-Erik Rosberg; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slug tests; well completion; re-injection; Well testing; pumping tests; injection tests; well development; pneumatic initiation; hydro-jetting; coiled tubing; tunnel lining; deep wells;

   Sammanfattning : Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. LÄS MER

3. 22. On Tracing Flicker Sources and Classification of Voltage Disturbances

   Författare :Peter Axelberg; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transmission and distribution; digital signal processing; power quality monitoring; light flicker; power system disturbance; support vector machines; Medicinteknik; voltage dips;

   Sammanfattning : Developments in measurement technology, communication and data storage have resulted in measurement systems that produce large amount of data. Together with the long existing need for characterizing the performance of the power system this has resulted in demand for automatic and efficient information-extraction methods. LÄS MER

4. 23. The importance of body-mass exponent optimization for evaluation of performance capability in cross-country skiing

   Författare :Tomas Carlsson; Michail Tonkonogi; Christer Malm; Klavs Madsen; Högskolan Dalarna; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allometric scaling; power-function modelling; maximal oxygen uptake; body mass; elite skiers; distance skiing; lactate threshold; double poling; sprint skiing; competition; power output; time trial; Hälsa och välfärd; Health and Welfare;

   Sammanfattning : Introduction Performance in cross-country skiing is influenced by the skier’s ability to continuously produce propelling forces and force magnitude in relation to the net external forces. A surrogate indicator of the “power supply” in cross-country skiing would be a physiological variable that reflects an important performance-related capability, whereas the body mass itself is an indicator of the “power demand” experienced by the skier.

5. 24. Applications of decision diagrams for low power synthesis

   Författare :Mikael Kerttu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

   Sammanfattning : Power consumption is an important design constraint for circuits used in portable devices. In this thesis an analytic approach to minimize the power dissipation of Binary Decision Diagram (BDD) mapped digital circuits is presented. LÄS MER

7. 25. Hydrogeophysics of Tropical Africa : Recent advances and perspectives

   Författare :Elónio Muiuane; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Sammanfattning : In the present work an attempt is made to put into perspective the hydrogeophysical investigations for rural water supply carried out over the last two decades in tropical Africa, paying special attention to groundwater targets in the weathered rocks in and above the crystalline basement. The applicability of geophysical techniques in groundwater investigations in tropical Africa, particularly the DC resistivity and electromagnetic techniques is discussed in the light of recent developments in instrumentation, data collection and interpretation procedures.
