1. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing
University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskapAbstract : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). READ MORE

2. Towards Sustainable Coffee Packaging: A Comparative Study of Current and Future Materials for Zoégas Coffee
University essay from Lunds universitet/FörpackningslogistikAbstract : An important factor in preventing food waste is the ability to provide a product with a package according to its needs. The packaging material, in turn, needs to be recyclable in order to contribute to a circular use of materials rather than becoming waste. READ MORE

3. Scenario Dose Calculation for Robust Optimization in Proton Therapy Treatment Planning
University essay from Lunds universitet/Matematik LTHAbstract : Robust optimization plays a vital role in proton therapy treatment planning. A monoenergetic beam of protons has a finite range and delivers most of its dose at some specific depth in the patient. This allows the design of treatments that mainly damage the tumor and not any surrounding tissue. READ MORE

4. Monte Carlo simulations of Linear Energy Transfer distributions in radiation therapy
University essay from Uppsala universitet/HögenergifysikAbstract : In radiotherapy, a quantity asked for by clinics when calculating a treatment plan, along withdose, is linear energy transfer. Linear energy transfer is defined as the absorbed energy intissue per particle track length and has been shown to increase with relative biologicaleffectiveness untill the overkilling effect.

5. Millimeter-Wave Pencil Beam Leaky-Wave Antenna
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Moving into higher frequencies, in occurrence withmodern applications, poses the issue of higher attenuation ofelectromagnetic waves, which in turn demand more directiveantennas. This paper proposes a directive antenna designoperating at 30GHz based on leaky-wave technology. Themodel consists of two main components. READ MORE
