In surveillance it is important that the recordings are accurate and in as high quality as possible. The surveillance surroundings and equipment can alter and change the audio and needs to be compensated for. This master thesis project investigates whether using multiple microphones could improve the audio quality. The project was limited to only use analog electronics and constricted itself to th
Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. The purpose of this thesis was to implement a material decomposition method, from the image acquisition
Background and aim: There is a high interest in determining the absorbed dose in tumors and organs for various radiotherapy cancer treatments. Due to limitations in today's methods of determining the patient specific absorbed dose it is usually not proceeded clinically. The methods are time consuming but also trying for patients, since it depends on several imaging procedures at different time
Software models can simulate hardware components to varying degrees of ac- curacy. On the extreme ends, there are purely functional models which have no concept of time and execute requests right away, and cycle-accurate models which capture all the implementation details and clock the time they take. In this thesis we study a model of an Arm Mali GPU which is a cycle-approximate model, meaning it
Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health conseq
This essay concerns the complementation of the English emotive verbs like, love, hate and prefer. In English, gerund-participial and infinitival complements often receive semi-synonymous semantic interpretations when complementing emotive verbs. All the while, both complement types supposedly convey separate semantic interpretations, resulting in that they commonly appear in contexts expressing ha
SkyTEM-mätningar, även känt som helikopterburna TEM-mätningar (transient elektromagnetisk metod) har utförts vid grundvattenmagasinet Ilstorp i vombsänkan. Resultatet från mätningarna har analyserats i syfte att förbättra kunskapen kring geologiska och hydrogeologiska förhållanden i magasinet. Grundvattenmagasinet Ilstorp är en jordakvifer där de vattenförande avlagringarna består av isälvs- och iSkyTEM, an airborne TEM (transient electromagnetic method), has been used to measure the resistivity of ground in and around the groundwater reservoir Ilstorp in Sjöbo municipality, Skåne, Sweden. The results of the measurements have been analysed in an effort to increase the knowledge about the geological and hydrogeological conditions of the reservoir. Ilstorp is a an aquifer that consists of fl
names, template names, and variables. Macros was used as a quick fix to create complex components. The result was five subprojects where each project explored different ways of designing the prototype. One way was to use macros to create cylinders and connect them to input and output signals in SIMIT. The second was to create templates and then use an Excel sheet to assign the signals. The templat
Theory is still inconclusive to what level income inequality affects economic growth, with little research accounting for the effects of human development. The paper aimed to analyze both the effects of income inequality on growth while controlling for the underlying effects of different human development indicators. This was done by using data of 55 countries for the period 1990-2019, with result
Molten salt applications are challenging from a material perspective. This degree project was carried out at Alfa Laval to give them a better understanding of the corrosion of solar salt on the standard heat exchanger material stainless steel 321. Similar tests have previously been performed externally. By developing test methods for in-house corrosion testing time and money can be saved. In thi
Ett av Sveriges hållbarhetsmål är att senast 2045 inte generera några nettoutsläpp av växthusgaser. För att uppnå detta mål krävs kraftiga åtgärder inom alla sektorer. En av dessa är bygg- och fastighetssektorn som 2018 stod för ca 22 % av Sveriges territoriella utsläpp av växthusgaser. Enbart cementindustrin står för ca 5–7 %. Cirka hälften av klimatpåverkan från moderna flerbostadshus uppkommer One of the main sustainability goals in Sweden is to reduce the nations greenhouse gas emissions to a net-zero level by 2045. This is a national implementation of the Paris- Agreement. To achieve this goal measures need to be taken in all industrial sectors. The construction and real-estate sectors are responsible for about 22 % of Sweden’s yearly territorial greenhouse gas emissions. The cement i
Visualisering är läran om hur man representerar information med visuella element. Datastrukturer kan tjäna på att visualiseras, då det kan öka folks förståelse för strukturen. Ju mer komplex en datastruktur är, desto svårare är det att hålla reda på de olika relationerna mellan olika objekt i strukturen utan en bra visualisering. Målet med detta examensarbete var att skapa ett verktyg för visualisVisualization is the discipline of representing information with visual elements. Data structures can benefit from visualization, enabling people deeper understanding of the structures. The more complex the data structure, the harder it can be to keep track of different relations between different objects in the structure without a good visual representation. The aim of this thesis was to create a
Syfte: Syftet med studien är att ge en översikt över hållbarhetsrapporter som är upprättade av organisationer med en indirekt påverkan på hållbarhet. Vidare ska det undersökas hur valda organisationer valt att redovisa sitt ansvarstagande i sina hållbarhetsrapporter. Teoretiska perspektiv: Studiens teoretiska ramverk utgörs av legitimitetsteorin, intressentteorin och Carrolls CSR pyramid. Teoriern
The aim of this paper is to analyze Peter Linde’s sculpture the Statue of Zlatan as a work of art in a public space and what kind of meaning is produced through its different kinds of expressions. Based on theories concerning public art, ancient Greek and Roman sculptural traditions and iconoclasm, this paper explains how the sculpture is drawing on older sculptural traditions to narrate the obser
Cancer Testis (CT) genes are restrictedly expressed in immune-privileged germ tissues and recognised as non-self antigens if aberrantly reactivated in tumours. Beyond their immunotherapeutic potential, certain CT genes have known oncogenic roles, reflecting highly specialised physiological functions in the germline. Meiosis-associated CT genes have been implicated as drivers of genomic instability
Pritam Kumarsingh A Case Study to develop and test GIS/SDSS methods to assess the production capacity of a Cocoa Site in Trinidad and Tobago Trinidad and Tobago has achieved world-wide affirmation for its unique fine and flavour cocoa (Theobroma cacao). This classification of cocoa commands price premiums on the global market. However, the industry has declined over years. Investors and farmers
