1. 1. Ultra-Wideband Time Domain Measurement Systems for Microwave Tomography

   Författare :Xuezhi Zeng; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time DomainMeasurement; Ultra-Wideband; EquivalentTime Sampling; Real Time Sampling; Microwave Tomography; Measurement Error; Frequency Domain Measurement;

   Sammanfattning : As a potential imaging modality for biomedical applications, microwave tomography has attracted a lot of interests in recent years. With microwave tomography, microwave signals are transmitted into the biological tissues and the scattered fields are recorded. LÄS MER

3. 2. Studies in Glacier Mass Balance : Measurement and its errors

   Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

   Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

5. 4. Rapid measurements of the moisture content in biofuel

   Författare :Jenny Nyström; Erik Dahlquist; Stefan Backa; Eva Thorin; Bo Franzon; Clarke Topp; Mälardalens högskola; []
   Nyckelord :radiofrequency measurement; moisture content measurement; fuel characterization; biofuel; time domain measurement; Bulk measurement; Multivariate data analysis;

   Sammanfattning : An increasing number of power plants in Scandinavia are beginning to use biofuel instead of coal or oil. The material in the new fuel is a mixture of woodchips, mostly Pine, Spruce and Salix, bark, GROT (tops and branches from felling waste) and sawdust from sawmills. It is heterogeneous, having a moisture content varying from 15% up to 65%. LÄS MER
