2. 1. Embedded Measurement Systems

   Author : Lars Bengtsson; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

   Abstract : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. READ MORE

4. 2. Reconstructing force from harmonic motion

   Author : Daniel Platz; David B. Haviland; John E. Sader; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator; force spectroscopy; atomic force microscopy; intermodulation; multifrequency; inverse problem; high quality factor;

   Abstract : High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. READ MORE

5. 3. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

   Author : Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
   Keywords : Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

   Abstract : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. READ MORE

6. 4. Experimental Measurement of Lateral Force in a Submerged Single Heaving Buoy Wave Energy Converter

   Author : Andrej Savin; Mats Leijon; Magnus Karlberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; Tight mooring system; Offshore measurement; Strain gauge; Estimation of stress; Lateral force; Inclination angle; Snatch load; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : The search for new solutions for the generation of energy is becoming more and more important for our future. Big arguments and disagreements on e.g. the questions of gas transport or the dependence on energy supplied by other countries raise demands on the development of new forms of alternative energy resources.

7. 5. Force measurements using scanning probe microscopy : Applications to advanced powder processing

   Author : Anders Meurk; KTH; []
   Keywords : atomic force microscope; AFM; SPM; van der Waals interaction; DLVO-theory; surface forces; colloidal probe; force curve; friction; adhesion; stick-slip; cantilever; calibration; spring constant; silicon nitride; iron; silica;

   Abstract : The object of this thesis is to apply scanning probemicroscopy (SPM) to the field of advanced powder processing.Measurement of interparticle surface forces at conditionsrelevant to ceramic processing has been performed together withthorough studies of powder friction. READ MORE
