1. 1. Heat Flow in Building Components, Experiment and Analysis

   Författare :Petter Wallentén; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiation exchange; longwave; shortwave; transient; frequency analysis; finite difference; measurements; wall; window; heat transfer coefficient; convective; full scale; natural climate; in situ; counter flow insulation; heat transfer; dynamic insulation; temperature; building; solar radiation; window model; Building construction; Byggnadsteknik;

   Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER

3. 2. Thermal Issues in Testing of Advanced Systems on Chip

   Författare :Nima Aghaee Ghaleshahi; Zebo Peng; Petru Eles; Jaan Raik; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SoC test; test scheduling; Adaptive test; Temperature awareness; Process variation; Thermal simulation; 3D stacked IC 3DSIC test; Burn-in; Temperature gradients; Temperature Cycling Test; Test Ordering;

   Sammanfattning : Many cutting-edge computer and electronic products are powered by advanced Systems-on-Chip (SoC). Advanced SoCs encompass superb performance together with large number of functions. This is achieved by efficient integration of huge number of transistors. LÄS MER

4. 3. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

   Författare :Mattias Nilsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

   Sammanfattning : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. LÄS MER

5. 4. To analyse measurements is to know!

   Författare :Henrik Gadd; Institutionen för energivetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Hourly meter readings; fault detection; Low return temperature; temperature difference.;

   Sammanfattning : Renewable energy sources dominated the world energy supply until the beginning of the 20th century, when fossil energy became the dominant energy source worldwide. Today, fossil fuels contribute to over 80% of world energy supply. But there are two major reasons why fossil energy use has to stop. LÄS MER

7. 5. Measurement and evaluation of body temperature : Implications for clinical practice

   Författare :Märtha Sund-Levander; Lis Karin Wahren; Ewa Grodzinsky; Karin Axelsson; Linköpings universitet; []
   Nyckelord :Assessment; body temperature measurement; elderly; evaluation; infection; nursing home; pneumonia; survival; MEDICINE; MEDICIN;

   Sammanfattning : The general aim was to explore factors influencing the normal variation and measurement of body temperature. Additional aims were to study morbidity, mortality and the clinical presentation of pneumonia and predictors for survival in elderly nursing-home residents. LÄS MER
