This master thesis is about improvement, optimization and further development of the sensory feedback in a prosthetic hand previously investigated at the department of Biomedical Engineering in Lund. The first approach will be to investigate and further see into the need of a sensory feedback in hand prostheses. There were several reports that showed that the lack of sensory feedback in hand prost
The chemical resistance is an important property for elastomers, especially for gaskets used in industrial applications related to food processing and packaging. Three common elastomers, namely silicone, FKM (fluorocarbon) and EPDM (hydrocarbon with carbon-carbon double bonds), were aged in harsh chemicals used in specific applications in Tetra Pak filling machines. Gaskets of these materials were
The complement system is a link between adaptive and innate immunity, which is a first line protection against pathogens. It can be activated through three different pathways which all lead to formation of C3 and C5 convertases and final complement-mediated lysis of cells. The system contains regulatory mechanisms at different steps of activation to avoid lysing of own cells. Recent years, have sh
Cardiac magnetic resonance is widely used to non-invasive image the heart, for both clinical and research purposes. Segmenting different parts of the heart provides important diagnostic information. Performing this task manually is time-consuming and operator dependent, hence it would be beneficial to automate this process. The aim of this thesis is to implement an algorithm to segment the right v
Choosing the correct database for an application can be a daunting task for an application owner. There is a vast plethora of different options to choose from, where choosing a NoSQL database or a relational database management system built on SQL is the most defining decision. With the ever-increasing amounts of data that is produced, more and more databases are emerging. In this report we comp
Research on the implementation of EU policies at national level are well studied, while the implementation of EU policies at the local level are underrepresented in the research. In Swedish municipalities there are municipalities that have implemented the circular to a greater extent than other municipalities. This thesis therefore, seeks the answer to how implementation of the Circular Economy in
This thesis explores the information-related needs and practices of Syrian refugees in Sweden as represented by six Syrians living in Scania County, Sweden, both during their journeys and after arrival in Sweden. The research adopts a qualitative approach through conducting semi-structured interviews in informal Arabic with Syrian refugees. The interviews were then thematically analyzed from the t
In Sweden, both house prices and household debt have more than doubled over the last two decades. This rapid surge has generated concerns about a housing bubble and the economic consequences that may follow, resulting in a considerable body of research analysing the fundamentals of Swedish house prices. To assess how a bubble or a crisis would ripple over the housing market, it is key to also unde
“Dzud” is a unique winter weather phenomenon with devastating effects on livestock and the people of Mongolia. As climate change continues to intensify, the social-ecological impacts of dzud worsens. This qualitative case study analyses the Mongolian government’s response to dzud and its following social-ecological impacts from second-hand material. A measuring instrument based on social-ecologica
Proteins are made up by amino acids linked through peptide bonds. They carry out many important tasks in our bodies and the folding of proteins is a crucial process. The folding of proteins determines the function of it and sometimes proteins get misfolded. The misfolded protein can get degraded, refold back or form protein aggregates. These aggregating proteins are related to several diseases for
For a drone to be able to navigate in an indoor environment, it needs to understand its surroundings and locate itself to be able to plan a trajectory to its final destination. This thesis aims to solve the global localization problem, i.e. estimate a drone’s position and orientation in a previously mapped indoor environment by using a monocular camera and computer vision, which is an important fi
In the age of ever-growing technological advancements, delegating some of the inherently human tasks to smart machines is becoming more and more common. The possibly new wave of industrialization – Industry 4.0 – is comprised of interconnected smart technologies that could automate parts of the production and decentralize the decision-making process. The associated efficiency has prompted business
Uppsatsen behandlar asymmetrisk kryptering över ändliga kropper och elliptiska kurver. Elliptiska kurver införs med hjälp av affint och projektivt rum. Uppsaten också ger en introduction till algoritmer som kan knäcka diskret logaritm problemet över kropper och elliptiska kurver.In this thesis, an introduction to public key cryptography over finite fields and elliptic curves is given. Elliptic curves are introduced using affine and projective spaces. The thesis also gives an introduction to algorithms that are able to break the discrete logarithm problem over finite fields and elliptic curves faster than an exhaustive search.
The movement of a rock glacier located at the bottom of the Foxfonna glacier, Svalbard, Norway, was studied through the use of photogrammetry and feature tracking software, between the years of 2017-2019, as well as elevation changes between 2009 and 2019. This could aid in further knowledge about the rapid velocity changes of rock glaciers in a continuous permafrost environment. It was found that
Oat starch, like starch from other plants, is composed of amylose and amylopectin. The arrangement and abundance of these polysaccharides offers distinct properties to the formed starch. Starch with an elevated amount of amylose is of commercial interest and amount of amylose present in oats differs within cultivars. In this study, a mutant oat population developed by CropTailor was screened usin
Throughout history it has always been crucial to accurately measure, track, and predict precipitation. This has been done using various methods with varying degrees of precision. As the world evolves and as urban areas expand, it has become more apparent that there is a need for a more efficient way to observe and record precipitation. During the summer of 2018, an X-band weather radar located in
