1. 21. The European Union’s Technological and Economic Development : A Study on Production of Renewable Energy

   University essay from Umeå universitet/Nationalekonomi

   Author : Ali Abbas; [2018]
   Keywords : ;

   Abstract : This thesis answer the two main questions, firstly, the role of technological development in the production of RE with special reference to investment subsidy in supporting schemes and research and development (R&D). Investment subsidies in supporting schemes and R&D are widely used to promote RE technology and considered economical, efficient instruments than regulation approach. READ MORE

3. 22. Deep Learning to Predict Hip Fracture Risk from Clinical DXA-images

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Karin Yip; Meral Husein; [2018]
   Keywords : hip fracture; osteoporosis; deep learning; neural network; DXA; Technology and Engineering;

   Abstract : Osteoporosis is a bone disease that is defined as low bone mineral density (BMD) and results in an increased risk of bone fracture. It is a serious public health problem that causes excess mortality and major economical and social impact. Today there are more than 8.9 million fractures connected to low bone mineral density worldwide. READ MORE

4. 23. Estimation of Noise and Contrast for CTA of the Brain

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Johannes Loberg; Miranda Gisudden; [2018]
   Keywords : CT - Computed Tomography - CTA- Computed Tomography Angiography - Photon Counting - CNR - Contrast to noise;

   Abstract : Computed tomography angiography (CTA) of the brain poses challenges on the imaging system; the contrast between blood vessels and surrounding soft tissue is very low, and to render small intricate vessel structures high spatial resolution is needed. Higher precision angiography would facilitate more accurate diagnosis of pathological conditions. READ MORE

5. 24. Design, Construction and Characterization of a Portable Fast-Neutron Detector

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Author : Nicholai Mauritzsson; [2017]
   Keywords : fast-neutrons; detector; plastic scintillator; NE110; neutron tracking; scintillation; spallation; european spallation source; sonnig; Physics and Astronomy;

   Abstract : At European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering instrument.

6. 25. Exploring the Use of Graphene as a Target Material for Laser Plasma Ion Acceleration

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

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

   Abstract : 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.
