1. 1. Optical Fiber sensing of acoustic waves using overlapping FBGs

   Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

   Författare :Erik Lillebø Hole; [2019]
   Nyckelord :Ultrasonic; Optical Fiber Sensing; Fiber Bragg Grating;

   Sammanfattning : The objective of this thesis was to investigate if an optical fiber sensing method with the use of two overlapping fiber Bragg gratings to measure Lamb wave $S_0$ modes in a steel plate, and how it would compare to traditional PZT transducers. A solution was proposed where the use of an optical fiber sensing system was built and took advantage of the strain dependence of a fiber Bragg grating mounted to a steel plate. LÄS MER

3. 2. Development and validation of a scanned proton beam model for dose distribution verification using Monte Carlo

   Master-uppsats, Stockholms universitet/Fysikum

   Författare :Erik Almhagen; [2015]
   Nyckelord :;

   Sammanfattning : Background and purpose: Although proton therapy is becoming increasingly common as a radiotherapy modality, facilities offering proton therapy are still scarce in comparison to photon therapy. Sweden's new proton therapy facility, Skandionkliniken, is scheduled to being operation during August 2015, employing the pencil beam scanning technique. LÄS MER

4. 3. Balanserade styrmått på en värdekedja

   Magister-uppsats, Ekonomiska institutionen

   Författare :Erik Bragg; Fredrik Skiöld; [1999]
   Nyckelord :Business and economics; Management Control System; Balanced Scorecard; Supply Chain; värdekedja; Svedala; Ekonomi;

   Sammanfattning : Bakgrund: Utvecklingen inom redovisningssystem går mot att använda alltfler kompletterande icke finansiella styrmått. Genom att koppla ihop det tankar som finns inom Balanced Scorecard konceptet med ett värdekedjetänkande som finns inom Supply Chain Management kan en horisontell styrning skapas. LÄS MER
