1. 6. Rip off and characterization of nanowire ensembles for photovoltaic applications

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Seyed Alireza Abrand Abadizadeh; [2014]
   Keywords : nanowire; solar cell; PDMS; flexible film; Physics and Astronomy;

   Abstract : The main aim of this project was to peel off the epitaxially grown nanowires (NWs) from their native substrate and transfer them to the cheaper carrier substrate in order to make solar cell device from transferred NWs. Potentially the peeling and transferring idea is about to decrease the cost of NWs growth by reusing the native substrate especially for expensive material such as InP and GaAs which are suitable materials for single junction solar cell.

3. 7. Fatigue Analysis of Threaded Holes : A project performed at ÅF using static structural analysis in ANSYS

   University essay from Institutionen för informationsteknologi

   Author : Andreas Olsson; Joel Sundström; [2013]
   Keywords : ;

   Abstract : The effect of a plain hole on the fatigue properties of a body undergoing uniaxial loading is a well-studied area. However, for the case of threaded holes that are not being used together with a bolt, little can be found in the literature. READ MORE

4. 8. Design and development of a testing device for a new invented Doctor Blade

   University essay from Avdelningen för maskin- och materialteknik

   Author : Mohamed Sadek; [2013]
   Keywords : Doctor Blade; testing device; design; FMEA-analysis; FEM-analysis; Kräppningsblad; testrigg; design; FMEA-analys; FEM-analys;

   Abstract : This thesis project is about designing and developing an already existing testing device for a new invented Doctor Blade. A doctor blade is a blade used for creping tissue paper of a rotating cylinder, Yankee Cylinder. The old testing device was incomplete in a way that a rotating cylinder was missing, hence the tested blade is not loaded properly. READ MORE

5. 9. Stabilizing a missile radar antenna Using Axiomatic Design

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Malin Kjellberg; [2007]
   Keywords : ;

   Abstract : This thesis work describes a brand new concept of how to, from a mechanical perspective, stabilize/mount a radar antenna. The antenna must be able to rotate ±60 degrees around pitch and yaw without disturbing the radar characteristics. At the same time the antenna diameter must be as large as possible to enhance radar quality. READ MORE
