In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
This study has sought to propose didactical approaches to find a balance between the teaching of classic and contemporary literature in the Swedish EFL classroom by exploring and comparing the attitudes of Swedish upper secondary school teachers and students towards both forms of literature. The study was conducted through two quantitative questionnaires, one researching the attitudes of 44 EFL st
As more and more In Vitro Fertilizaiton (IVF) treatments are performed each year, there is a need to better predict the outcomes of different stages of the treatment and hence get a better understanding of which hormonal and physical parameters affect the treatment outcome and in what way. In this study, the effect of interaction between baseline AMH (anti-mullerian hormone) and DFI (DNA fragmenta
Det får anses vedertaget att barn är en särskilt utsatt grupp världen över. Gifta barn, som dessutom är asylsökande, är alldeles särskilt sårbara. Insikten om detta bör genomsyra all lagstiftning som avser barn, där barnets bästa ska sättas i främsta rummet. Uppsatsens övergripande syfte har varit att undersöka ett i utlandet gift barns rätt att i Sverige återförenas med sina föräldrar. Syftet ha
Barnkonventionens artikel 3 och 12 ger uttryck för två centrala principer inom barnrätten, vilka även är fastställda i andra svenska lagar som föräldrabalken och lagen med särskilda bestämmelser om vård av unga. Principen om barnets bästa innebär att vid samtliga åtgärder som rör barn ska barnets bästa vara avgörande. Vid denna bedömning ska varje barn få chansen att uttrycka sina åsikter, vilka s
Entrepreneurship education has grown rapidly and there is a steady increase in entrepreneurship courses and programs worldwide. For the past decade, research topics in entrepreneurship education have mainly been related to the entrepreneurial intentions, actions, and learning process of students. However, not much research related to entrepreneurship educators has been conducted. Specifically, the
Kraftringens geotermianläggning i Lund har varit i drift sen 1984. Det är den enda stora geoter-miska anläggningen i Sverige. Efter mer än 30 års drift är det dags att utvärdera hur det har fungerat. Arbetet be-skriver de geologiska förutsättningarna som stratigrafi (formation), formationstemperatur, typ av akvifer, porositet, permeabilitet och vattenkemi, samt driftdata, systemuppbyggnad, funktioThe geothermal heat plant in Lund has been running since 1984. It is the only one of its kind in Sweden. After running for more than 30 years it’s now time to evaluate the experiences from the long operational period of the heat plant. This report describes the geological conditions like the formation, temperature of the geothermal water, aquifer, porosity, permeability, and chemistry of the forma
Today’s human population is continuously increasing and this also increases the need of exploiting natural habitats. Increased exploitation results in loss of important habitats for different organisms, which in turn leads to biodiversity loss. The loss of biodiversity endangers the supply of ecosystem services, which is fundamental for human well-being. To mitigate the loss of biodiversity and ec
As computer systems grow larger and more complex, the task of maintaining the system and finding potential security threats or other malfunctions become increasingly hard. Traditionally, this has had to be done by manually examining the logs. In modern systems, this can become infeasible due to either the large amount of logs or the complexity of the system. By using machine learning based anomaly
Data is a crucial resource for machine learning. But in many settings, such as in healthcare or on mobile devices, there are obstacles that make it difficult to utilize the available data. This data is often distributed between many clients and private, meaning that central storage of the data is inadvisable. Further, image data is often unlabeled and external labelling is impossible due to its pr
Continuous production control is important for the production using Tetra Pak equipment, as problems that are found early in the chain of production can minimize the need for waste greatly. In production of paper straws, a possible production control could be to photograph straws during production, analyse these and predict how good the straw is, using the image. If the predicted performance of th
This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults). The sample with a pu
Our thesis aimed to investigate how the Swedish district courts and appellate courts present arguments for visitation rights while safeguarding children's rights in custody cases involving instances of violence. The analysis and concluding discussion focused on three research questions: How do the district courts and appellate courts argue on visitation rights in custody cases involving instan
The building sector uses about 40% of the total global energy use. Sweden aims to reach its new goal to reduce the energy use in their residential sector as well as commercial sector by 20%, which should be reached by year 2020 and 50% by year 2050. To find a solution to this problem European Union (EU) collaborated with IVL (Swedish environmental Research Institute) and LKF (lunds Kommuns Fastigh
Ensuring close control of critical quality attributes (CQAs), such as post-translational modifications (PTMs), in therapeutic monoclonal antibodies (mAbs) is essential for maintaining function and batch homogeneity in large-scale production. Common PTMs include deamidation, fragmentation, oxidation, charge variants, and glycosylations. This study aimed to evaluate CQA variations and correlate the
To properly understand regions of space behind interstellar dust, like the Galactic bulge, infrared (IR) observations are needed, as it passes through the dust with minimal absorption. In the past few decades, the development of IR telescopes has allowed for a much deeper understanding of our Galaxy’s stellar populations and history. To properly use the data which these IR telescopes produce howev
The Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
This thesis explores the Swedish EdTech sector, specifically investigating the commercialization of Virtual Reality (VR) technology as an innovation. Conducted as a case study in collaboration with Edda Knowledge, it aims to address a research gap identified by several scholars who note that the research field of commercialization process and stakeholder theory has predominantly focused on expert
Prior to the adoption of Article 17 of the Directive (EU) 2019/790 on Copyright and Related Rights in the Digital Single Market, the e-Commerce Directive provided hosting liability exemptions for intermediary service providers. In addition, copyright exceptions and limitations were previously optional and their implementation was at liberty of the Member States. Under the new Article 17 Member Sta
