2. 1. Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators : Fabrication and Characterization of Superconductive Coplanar Waveguide Resonators

   Author : Adem Ergül; David B. Haviland; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coplanar; Waveguide; Resonator; Superconductive; Fabrication; Characterization; Superconductivity; Supraledning;

   Abstract : The objective of this thesis is to evaluate a generic process for fabrication and characterization of the Superconductive coplanar waveguide (CPW) resonators. Superconductive CPW resonators with various lengths and shapes are designed to investigate their electrical and magnetic properties as well as resonance properties and sensitivities. READ MORE

   Abstract : Tungsten (W) is listed among the European Union (EU) critical raw materials (CRMs) for its supply risk and economic importance. Primarily, tungsten is produced from scheelite and wolframite mineral ores with 0.08-1.5% tungsten trioxide (WO3) grade. READ MORE

5. 3. Manufacturing and Characterization of Cellulose Nanofibers

   Author : Carl Moser; Mikael Lindström; Gunnar Henriksson; Kristin Syverud; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Nanofibers; Characterization; Homogenization; Endoglucanase; TEMPO; Specific surface area; Atomic force microscopy; Cellulosa; Nanofibrer; Karakterisering; Homogenisering; Endoglukanas; TEMPO; Specifik ytarea; Atomkraftmikroskopi; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. READ MORE

6. 4. Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes

   Author : Janne Paavilainen; Chris Bales; Jan-Olof Dalenbäck; Lennart Gustavsson; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flue gas; measurement; characterization; averaging Pitot tube; SolNET;

   Abstract : Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. READ MORE

7. 5. Upconversion in Er doped silica : - characterization and modeling

   Author : Dmitry Khoptyar; Bozena Jaskorszynska; Anders Bjarklev; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Abstract : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. READ MORE
