1. 1. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Pablo Martinez Cano; [2019]
   Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

   Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

   Abstract : En atom består av en kärna och en eller flera elektroner. Den positivt laddade kärnan utgör atomens centrum och större delen av dess massa. Elektronerna är små, negativt laddade, partiklar i omloppsbana kring kärnan. READ MORE

4. 3. Surface Roughness Measurment: Multi-bandFrequency Shift Interferometer based onPolarization Measurement

   University essay from Högskolan i Halmstad/Tillämpad matematik och fysik (MPE-lab)

   Author : Amir Arashlouzadeh; [2014]
   Keywords : ;

   Abstract : Optical measurement techniques have been gaining ground for their vast applications in industry and scientific purposes. These techniques are beneficial comparing to the mechanical methods. Non-intrusive, robust, high accuracy and small measurement volume are some of the advantages of the optical metrology. However, these approaches are expensive. READ MORE

5. 4. Precision Amplifier for Applications in Electrical Metrology

   University essay from Elektroniksystem; Institutionen för systemteknik

   Author : Stefan Johanssson; [2009]
   Keywords : Electrical; Metrology; Precision; Buffer; Amplifier; CMRR;

   Abstract : This master's thesis addresses two main problems. The first is how to suppress a common mode voltage that appears for current shunts, and the second how to let a voltage divider work under an unloaded condition to prevent loading errors and thereby a decreased measurement accuracy.
