Streaming video over the internet can face issues when met with poor and varying network conditions, which can be especially noticeable when streaming live video such as security footage or video calling. To handle this, there exists congestion control algorithms that monitor network conditions based on feedback from the receiver and adapt the video output. This thesis aims to implement and compar

Voice impersonation is a technique that has often been used by criminals whose goal is to avoid being identified while committing a crime. There are, however, other interesting cases where the police confronts a suspect with an incriminating recording, and the suspect would deny being the true speaker in that recording, and claim that it belonged to an expert impersonator. In both of these cases,

In the framework of this thesis, the optimization of the etching process of GaN for FinFET applications has been investigated. FinFETs are transistors with a vertical architecture in the shape of fins. These fins are fabricated by etching a pattern into a GaN substrate. The etching is carried out in two steps, a dry etch and a wet etch. In this thesis, these etching steps have been carried out whi

The demand for alternative sources of protein has increased; the so-called “protein shift” is an inevitability. Mycoprotein, a foodstuff produced from the mycelium of filamentous fungi, has gained popularity among consumers. Mycoprotein is grown in submerged culture, in either a simple or a complex, undefined medium. Strategies for yield increase in either medium were studied in this paper. For s

Proteases are a group of enzymes that are involved in breaking down larger proteins into smaller polypeptides or single amino acids, and they are used in various applications. In this project, the potential of budding yeast Saccharomyces cerevisiae as host for the construction of protease libraries is evaluated. Three model proteases of bacterial origin are used to evaluate transformation efficien

Despite developments in economic growth theory, the importance of savings and investment has remained consistent. It intrinsically connects to the importance of functioning financial intermediation and high levels of financial inclusion. While Sub-Saharan Africa still lags, Tanzania has during the last decade seen a rapid rise in mobile money services. This paper attempts to answer the potential o

Denna framställning redogör för beskattningen av derivatinstrument i inkomstslaget näringsverksamhet. I inkomstskattelagen delas derivatinstrument upp i lagertillgångar eller kapitaltillgångar baserat på vilken typ av aktiebolag som äger tillgången. I bolag som huvudsakligen bedriver handel med värdepapper anses sådana tillgångar vara lagertillgångar. I alla andra bolag är derivat kapitaltillgånThis thesis describes the taxation of derivatives in the business income tax act (“Inkomstslaget näringsverksamhet”). The Income Tax Act divides derivative instruments into inventory assets or capital assets based on the type of company that owns the asset. Assets held by companies engaged primarily in the trading of securities and derivatives are considered to be inventory assets. In other compa

Bakgrund: Dörröppningar till operationssalen under pågående operation påverkar ventilationen, vilket kan öka risken för postoperativ sårinfektion. Vid ortopedisk implantat- och allmän ortopedisk kirurgi ska ultraren luft uppnås för att förebygga vårdrelaterade infektioner. Syfte: Syftet med studien var att undersöka frekvensen av dörröppningar till operationssalen vid ortopedisk implantatkirurgi i

Vid en klinisk utredning av en patient med en ätstörning utförs en så kallad kroppsuppfattningsbedömning där patienten får utföra skattningar på olika kroppsmått. Dessa jämförs med de faktiska måtten och genom beräkningar fås ett mått på patientens kroppsuppfattning. Skattningarna görs med hjälpverktyget, EGON, vilket utvecklades 1985. Då systemet är i ständigt reparationsbehov samt är väldigt sv

This paper deals with the problem regarding the temporality of the future residence permits in relation to recruiters’ reflections on their recruitment process. The study is based on interviews with recruiters from two municipal organizations. The material from the interviews are analysed with a critical approach to neo-liberalism and with the help of theories about racialization processes, migrat

Att utbilda och fortbilda sina anställda är en viktig process för företag. Det krävs mer och mer för att företag ska hålla kvar sina anställda och möjligheten att utvecklas och fortbildas är något anställda ser positivt på. När samhället har digitaliserats så har processerna förändrats och digitala systemstöd har blivit en vanlig del av HR-avdelningens arbetsuppgifter. Ett systemstöd som används f

The building industry, like many others, are currently experiencing the effects of the digitalization, and the increased spread of smart buildings is a result of this. Much research has been done on smart buildings and their predecessors intelligent buildings, but there is limited research available on how entrance systems should be designed for smart buildings, especially regarding their connecte

The framework for isogeometric analysis (IGA) is presented, especially the construction and use of non-uniform rational B-splines (NURBS) to represent geometry, and a method utilizing IGA for structural optimization both for linear elastic and non-linear elastic deformations is implemented. Topology optimization of a linear elastic cantilever is performed, showing that IGA is inecient for topology

Climate change is a long-term challenge that requires urgent actions. An increased amount of greenhouse gases in the atmosphere, causing changes in the climate system such as melting glaciers and extreme weather conditions, are correlated to economic growth. To mitigate climate change, there is a need to evolve efficient strategies to reduce greenhouse gas emissions from companies within all branc

A system for affective touch has been constructed, in a study of humanoid and social robotics. The system detects, processes and analyses signals from touch, identifies touch types, and provides a corresponding emotional response and expression. Touch is detected on an Epi humanoid robot head through the use of conductive paint on the inside on the head shell, and the electrical signal produced is

Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. Topological relationships are for instance relations

The Hanson Larson evolution model assumes that wave height grows or decays from an initial condition towards an equilibrium wave height through a simple exponential growth. The model uses wind input data, fetch length and depth measurements. Using this input parameters, it both determines the wave height and period values, thus predicts wave climate. The model is developed using deep water conditi

This thesis highlight why the goals of increased cycling are not achieved, despite the fact that many municipalities establish policies and strategies to increase the use. Malmö and Mölndal have been reviewed based on how they work with bicycle planning, how cycling has developed over the past years and how the bicycle infrastructure is today. A culture of benefit to cyclist’s identity must be cr

This thesis aimed to develop and create a tool for 3D-artists at Sony Mobile Communications to improve and simplify the work when rendering new materials for their new products. The tool consists of a new product that would capture images for a panorama, where the images would contain a lot of light information, resulting in high dynamic range (HDR) files. This would be done by using the camera of
