Computed tomography (CT) segmentation models are frequently used within radiotherapy treatment planning, but similar models are not available to the related imaging modality cone beam computed tomography (CBCT) due to the scarcity of labeled data from this domain. Such models could have multiple clinical applications whereby it is of interest to study whether the CT segmentation models can be adap
With the increase in computational power, deep learning algorithms have become an active field of research over the last 7 years. These data-driven machine learning algorithms have produced good results in many applications, image analysis being one of them. Today, many image analysis tasks in the medical field are done manually, taking valuable time and effort from professionals. Automating some
Raman spectroscopy is well known as a method that can be used to study the structural characteristics of carbon materials such as soot and carbon black. In this work, a Raman spectroscopy setup was used to record spectra of various carbonaceous samples under different experimental conditions. The wave-number range of interest was from 900 to 3300 cm-1, which includes the first and second order Ram
Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. The interaction between light and biological tissue is mainly
In peritoneal dialysis ultrapure water used is produced from tap water by using several filter cartridges in series. One of the cartridges is an ion exchange filter removing cations and anions by either reverse osmosis membrane or chemical ion exchange resin. The ion exchange filter that is investigated in this thesis is a chemical ion exchange filter. The current chemical ion exchange system has
The core objective of this project was to design a controller for a drone (or quadcopter) that would allow the drone to keep a target in the center of a video filmed by a camera mounted on the drone. This was done by controlling the pitch of the gimbal, on which the camera was placed, and the yaw of the entire drone combined with using an image recognition program that could identify the target. F
Det finns många olika utformningar av lyfthjälpmedel och hjälpmedel för att gå, så som patient lyftar och rullatorer, men det finns inte många lösningar som kan göra båda. Detta examensarbete är baserat på en person med fysisk funktionsnedsättning som har specifika behov för vilka det inte fanns någon anpassad lösning. Målet var att utveckla en produkt som kan lyfta användaren från sittandes till There exist many different designs of lifting aids and walking aids, but barely any solutions that can do both. This thesis is based on a person with mobility impairment with specific needs for which there were yet no adapted solution. The goal was to design a product that can lift the user from sitting to standing position and then be a walking aid by supporting the user by the armpits, all this
Den svenska missbruks- och narkotikamodellen bygger på en restriktiv straffrättslig kontroll med ett narkotikafritt samhälle som mål. Trots detta har Sverige idag högst narkotikarelaterad dödlighet i Europa. Portugal använder istället en modell där skademinimering är centralt och förvärv och innehav avsett för eget bruk samt eget bruk är avkriminaliserat. I dagsläget verkar också Norge ta in på etThe Swedish drug control strategy is based on restrictive criminal law where the goal is a society free from illicit drugs. However, today Sweden has the highest drug-related mortality in Europe. Countries like Portugal use a different model where harm reduction is central and acquisitions, personal possession and consumption are decriminalized. Norway is also taking an interest in switching to a
Training Generative Adversial Networks (GANs) for image synthesis problems is a largely heuristical process that is known to be fickle and difficult to set up reliably. To avoid common failure modes and succeed with GAN training, one needs to find very specific hyperparameter settings carefully tuned to the model architectures and datasets at hand. Standard GAN training optimization methods such a
Power reduction is becoming a critical design requirement for ASIC/SOC designers. Reducing both dynamic and leakage power is essential to meet power budgets for portable devices as well as to ensure that these ASICs meet their packaging and cooling costs. In addition, the power of an ASIC has a significant impact on its reliability and manufacturing yield. Also, low-power has become a leading des
Multi-storey buildings constructed in timber have become more common in recent years. A reason for this lies in the growing interest for sustainable building, where timber is seen as a particularly interesting alternative. As efforts have been made to improve the heat insulation in buildings, the energy consumption from manufacturing materials and from constructing buildings, referred to as embodi
Title: Identification and suggestions of emerging technologies for a smart warehouse Authors: Xinchuan Li, Monish Ashok Kumar Background description: The warehouse is a crucial point and one of the most vital logistics and supply chain management links. Warehouses are built to smooth the supply chain and can be divided into different classifications. The importance of warehouses has increased a lo
During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance
This thesis seeks to explain constraining effects of distance to markets on agricultural smallholder’s ability to commercialise, using Zambia as a case. Despite a growing consensus that inaccessible markets constrain the development of broad-based agricultural growth, creating socio-economic regional disparities, the exact nature by which distance and market access interact with agricultural produ
In an age of increasing usage of heavily interconnected platforms, graph databases have increased in popularity due to their ease of modelling these systems. This thesis will evaluate if the graph database Neo4j can be used to model Lime's CRM System efficiently by comparing the performance of Neo4j and MS SQL on queries similar to those existing in Lime CRM. To benchmark the databases, they w
Detta project utfördes i samarbete med svenska förpackningsföretaget Tetra Pak Packaging Solutions AB. Deras huvuduppgift är att utveckla förpacknngsmaterial, processer och maskinlinjer som krävs för att producera laminatet, vilket är att flerskiktsmaterial som vanligtvis består av papper, plast och aluminium för att skapa en stark och skyddande barriär för flytande livsmedel. För att skapa laminaThis project was carried out in cooperation with Swedish packaging company Tetra Pak Packaging Solutions AB. Their main purpose is to develop the packaging material, process, and machine lines needed to produce the laminate, which is a multi-layered material typically made by combining paper, plastic, and aluminum to create a strong, protective barrier for liquid food packaging. In order to create
Menstrual health is essential for people who menstruate to fully participate in daily life and social activities. It is also a fundamental human right that closely impacts the realization of other rights such as right to non-discrimination and education. In recent years, there has been increasing attention to menstrual health on both the international and national levels. However, significant barr
NMDA receptors are ligand-gated ion channels assembled as heterotetramers composed of glycine-binding GluN1 and GluN3 subunits (GluN3A-B), and glutamate-binding GluN2 subunits (GluN2A-D). Their involvement in various psychiatric and neurological disorders makes them potential therapeutic targets. However, compared to the extensively studied GluN1/2 NMDARs, the functional, physiological, and pharma
An optical system for digital light processing car headlamps was designed and optimized in this project. The specifications include five lens elements and a field of view of 15 degrees horizontally and 7.5 degrees vertically. The system consists of an illumination module and a projection lens assembly. A high-brightness LED source and a rectangular light integrator ensure uniform illumination on t
