1. 21. Exploring the Use of Graphene as a Target Material for Laser Plasma Ion Acceleration

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Hannes Pahl; [2017]
   Nyckelord :Laser Plasma Acceleration; Target Material; Graphene; Physics and Astronomy;

   Sammanfattning : The interaction of a solid target with an ultra-high intensity laser pulse can result in the laser plasma acceleration of ions. The recent proposal of a new laser plasma ion acceleration scheme, named chirped standing wave acceleration, has created interest in a new class of ultra-thin solid target materials, either freestanding or as a part of novel compound targets.

3. 22. Multi-objective optimisation algorithms for GIS-based multi-criteria decision analysis : an application for evacuation planning

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Jose Ignacio Diaz Gonzalez; [2016]
   Nyckelord :decision-making; decision analysis; optimisation algorithm; multi-objective; multi-criteria; GIS; geography; physical geography; SPSO; NSGA-II; AMOSA; MOGWO; GEM; Earth and Environmental Sciences;

   Sammanfattning : Geographic Information Systems (GIS) have acquired greater relevance as tools to support decision-making processes, and during the last decades they have been used in conjunction with Multi-Criteria Decision Analysis techniques (GIS-MCDA) to solve real-world spatial problems. GIS-MCDA can be generally divided in Multi-Attribute and Multi-Objective techniques. LÄS MER

4. 23. Sensitivity Study of Semisubmersible Motions to Hull Form Parameters and Their Optimisation

   Master-uppsats, KTH/Marina system

   Författare :Elin Ogeman; [2014]
   Nyckelord :;

   Sammanfattning : An optimisation routine is developed to find the optimal size of a semisubmersible regarding the seven geometrical variables, column radius, column draught, pontoon height, pontoon beam, horizontal column distance and total underwater beam. Depending on the user’s input, the objective function consists of both heave, roll and pitch motions in several different wave directions. LÄS MER

5. 24. RFID Tag : RFID tag positioning and identification by using infrared and visual wavelength

   Kandidat-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Författare :Ender Gülerman; [2012]
   Nyckelord :RFID; Positioning; Image analysis; video processing; PCB; EMC; Balun;

   Sammanfattning : This thesis project aims to develop an active Radio Frequency Identification tag (RFID) which uses an interesting method for positioning and ID detection. In this project, rather than classical ways of positioning methods such as triangulation or radio maps, infrared light and a camera with an infrared filter was used for the positioning. LÄS MER

7. 25. Optimization of activity level in rCBF SPECT using the observer study Visual Grading Regression

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Sofia Kvernby; [2012]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : The purpose of this work is to assess the activity level needed to achieve satisfactory diagnostic information in regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) by introducing a new evaluation method to be used for and hopefully facilitate optimization studies in nuclear medicine in the future. The purpose is further to perform a visual grading study and investigate the use of this new evaluation method, Visual Grading Regression (VGR). LÄS MER
