This thesis theoretically investigates electronic transport in different low dimensional nanostructures. The miniaturization of electronics means that we reach a limit where quantum effects play a role in electronic devices. To understand and improve electronics at this level it is important to understand the transport properties. Excellent control over the nanostructures also makes them a great p
The characteristics of an Elekta amorphous silicon (a-Si) electronic portal imaging device (EPID) in response to a 6 MV photon beam generated without a flattening filter, an unflattened beam, have been determined. The characteristics were then compared to those for a conventional photon beam generated with a flattening filter in the beam, a flattened beam, in order to determine the suitability of
Context.Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these allow us to derive orbital and stellar parameters that are key to understanding the stellar populations of the Milky Way and to perform Galactic archaeology. Aims. We used the calibrate
Tailoring the activity of an organometallic catalyst usually requires a targeted ligand design. Tuning the ligand bulkiness and tuning the electronic properties are popular approaches, which are somehow interdependent because substituents of different sizes within ligands can determine inter alia the occurrence of different degrees of inductive effects. Ligand basicity, in particular, turned o
This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty. One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the s
Context: Scope management is a core part of software release management and often a key factor in releasing successful software products to the market. In a market-driven case, when only a few requirements are known a priori, the risk of overscoping may increase. Objective: This paper reports on findings from a case study aimed at understanding overscoping in large-scale, market-driven software dev
Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the
Objective: To investigate the influence of cardiovascular risk factors, including fasting plasma glucose (FPG), on the association between electrocardiographic (ECG) and echocardiographic left ventricular hypertrophy (LVH) in an elderly population. Methods: We tested cross-sectional associations between electrocardiographic and echocardiographic LVH, defining LVH according to the Sokolow-Lyon volt
Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. To support this, more flexible network solutions have merged in 4G, introducing new technical problems to the mobile terminal. New techniqu
Genom att utvärdera Skochparametern och skapa tre konceptkompressorer har examensarbetet försökt komma till en slutsats om hur bladens längdförhållande påverkar en kompressors verkningsgrad och stabilitet. Skochparametern visade sig fungera mindre bra som ett verktyg och det visade sig att ett lägre längdförhållande innebar en liten minsking i verkningsgrad, men en betydande ökning i stabilitet. The design of an axial compressor is mainly the trade-off between efficiency, stability and cost. A parameter that affects all of these three aspects is the blade aspect ratio. Due to the intricacy and complexity of the flow in a compressor, solely the effect of the blade aspect ratio variation is difficult to obtain. A parameter that supposedly is a gauge of the combined airfoil and end wall loa
Solcellsparker blir både allt vanligare och allt större. I denna studie undersöks hur storleken och antalet transformatorer i en solcellspark påverkar dennas förmåga att leverera el. De rådande klimatförändringarna är en av de största utmaningar mänskligheten ställts inför. Fossil elproduktion är en stor bidragande faktor till utsläpp av växthusgaser globalt. Solceller ser ut att spela en avgöranThe main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated
The rapid development of generative AI systems such as large language models (LLMs) and image generators have revealed critical tensions between technological innovation and existing data protection frameworks. This thesis examines the practical challenges related to the right to erasure established in Article 17 of the GDPR, commonly known as the "right to be forgotten" in the context o
Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter. Plotting these stars as [C/O] vs [O/H], it is revealed
Hur bra förser de urbana träden i Malmö pollinerare med mat? Antalet pollinerande insekter minskar. En av de främsta anledningarna till detta är förlust av blomresurser till följd av ett ändrat användande av landskap. I jämförelse med allt mer homogena jordbrukslandskap kan städer potentiellt bidra med mer födoresurser för vilda bin och andra pollinerare. Träd, som utgör en stor komponent av urbPollinating insects are declining due to several threats, one being a loss of flower resources because of a change of land use. With rural agricultural areas becoming more homogenous, urban areas might provide refuge for pollinating insects. The main aim of this study was to investigate how the trees in the city of Malmö, Sweden, contribute with food resources, i.e. nectar and pollen, both spatial
The term bibliotherapy is well known in several scientific fields as well as among practitioners in the US and in the UK, but in Sweden there seems to be a more modest use of the term as well as presence of practical bibliotherapeutic activity. On the other hand, some of the effects of reading that are commonly associated with bibliotherapy in the scientific literature seems to be similar to the e
Detta arbete handlar om en behandlingsteknik för hudterapi där lågenergetiska elektroner utnyttjas för strålbehandling där patienten står eller sitter på en roterande plattform. För att behandlingen skall få ett lyckat resultat krävs en viss stråldos (den absorberade energin per massenhet) till patientens hud. För att kontrollera att dosen är rätt används normalt mätningar med olika detektorer. DeBackground and purpose: This study refers to a rotational radiotherapy technique for the treatment of mycosis fungoides. Patients are irradiated by a high dose-rate low-energy electron beam while they stand on a rotating platform. This report presents a first effort to use the Geant4 simulation program to calculate the relation between the stationary and rotational depth dose distributions in an e
Formulating and implementing agricultural policies are important for the development of the agricultural sector and the rural population. The process of policy making is a political bargain between politicians and citizens. The outcome of this process, the policies, cannot be expected to be Pareto efficient resource allocations since altruistic behaviour is not very likely. All participants in the
