2. 1. Characterization of factors interacting in CGI machining : machinability - material microstructure - material physical properties

   Author : Anders Berglund; Cornel Mihai Nicolescu; Tero Stjernstoft; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGI; Compacted Graphite Iron; milling; cast iron; machinability; material microstructure; material physical properties; CGI; kompaktgrafitjärn; fräsning; gjutjärn; skärbarhet; mikrostruktur; materialegenskaper; Manufacturing engineering; Produktionsteknik;

   Abstract : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. READ MORE

4. 2. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

   Author : Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. READ MORE

5. 3. Silicon micromachined waveguide components for terahertz systems

   Author : Bernhard Beuerle; Joachim Oberhammer; Umer Shah; Kamal Sarabandi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromachining; waveguide; terahertz; deep reactive ion etching; silicon on insulator; on-wafer characterization; InP; SiGe; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents silicon micromachined waveguide components for sub-terahertz and terahertz (THz) systems fabricated by deep reactive ion etching (DRIE). Historically the main driving force for the development of THz systems has been space-based scientific instruments for astrophysics, planetary and Earth science missions. READ MORE

6. 4. Porcelain veneering of titanium : clinical and technical aspects

   Author : Per Haag; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Guld- och andra legeringar har i många år använts som material vid framställning av kronor och broar för ersättning av skadade eller förlorade tänder. Emellertid har tvivel uppstått kring lämpligheten av att använda guldlegeringar i tandersättningar, då guld har visat sig kunna ge biverkningar i form av allergiska reaktioner. READ MORE

7. 5. Performance-based costing as decision support for development of discrete part production : Linking performance, production costs and sustainability
