The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested. The latter are b
Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. The goal of this work is to asses the water quality dynamics t
LARO is a treatment method with strong scientific support, among things it is included in being considered "best practice" according to the EU's EMCDDA. However, despite the scientific support, the treatment is perceived as controversial and has received much criticism. The aim of this study was to research what professionals within LARO themselves consider to be the strengths and we
Downstream processing is an essential part in the production of biomolecules and the optimization of these processes are of great value, since they can be both time consuming and expensive. One common type of enzyme used in different biotechnical approaches is proteases and in this study Protease X was investigated. In order to use the enzyme in a process, a purification procedure needs to be esta
Structural transformation is a broad concept that has been widely argued to be of great importance for long-run economic growth. A common historical pattern highlights the labour shift out of agriculture towards manufacturing and industry sectors as the main characteristic of structural transformation. Today, large parts of the world are industrialized, as a result of a successful structural chang
Due to accidental external explosions ,which is not handle in the Eurocodes, are structural designers looking for other ways to design loads for external loads due to explosions. This combined with lighter building structures is a reason to address the issues of analysing the dynamic behavior of buildings subjected to air blasts from these extreme situations. The structural designers analyze the
At its core, language is multimodal (Kendon, 1986; McNeill, 1994), and information presented through different channels of information, such as visually, in the shape of gestures, or verbally, in the shape of speech or signs, together facilitate online language processing (Kelly, Healey, Özyürek, & Holler, 2015; Kelly, Özyürek, & Maris, 2010). This thesis extends previous studies on multim
Bioenergy derived from agricultural biomass has potential to phase out fossil energy sources while strengthening the bioeconomy. To estimate the agricultural sector's potential to meet the rising demand for renewable energy sources, it is crucial to understand what motivate farmers to sustainably increasing agricultural feedstock production. Through eight semi-structured interviews, and online
Kerguelenöarna är en vulkanisk ögrupp belägen i det södra Indiska oceanen. Öarna ligger på polarfronten samt inom den cirkumpolära Antarktiska strömmen och södra halvklotets västvindsbälte. Detta gör Kerguelenöarna till en intressant plats för klimatstudier. Av denna anledning erhölls en tre meter lång sekvens av sediment från en sjö på ögruppen 2013. Kol-14 datering av sjösedimenten gav ett gåtfuThe Kerguelen archipelago is a volcanic island group in the southern Indian Ocean. It is located on the polar front as well as within the Circumpolar Antarctic Current and the Southern Hemisphere Westerly Wind Belt. This makes it an interesting location for paleoclimate studies. For this reason, a three meter long sediment sequence from a lake on the archipelago was retrieved in 2013. Radiocarbon
Idén till det här examensarbetet föddes när vi tillsammans tillbringade en termin i London för snart tre år sedan. Vi bodde nära Hackney City Farm, en stadsbondgård i östra London. Ett stenkast från bullrande vägar och röda dubbeldäckare fanns får, kor, getter, åsnor, höns och grisar mitt i stan. Vi blev berörda och fascinerade av närheten mellan djur och människa i en urban miljö. I vårt examensInitially the idea for this thesis was born when we spent a semester together in London about three years ago. We lived close to Hackney City Farm, in the heart of eastern London. Within a stone’s throw from noisy roads and red double-deckers there were sheep, cows, goats, hens and pigs right in the middle of the city. We were fascinated and inspired by the closeness of animals and humans in a ver
To reduce the use of resources, as well as to minimize the effluents of carbon dioxide; we need to use our products for a longer time. Repairs makes that possible and is considered a key strategy to move towards a more circular economy (CE). Sweden recently presented its CE action plan, which includes few direct initiatives that would foster repairs. Therefore, through a literature review, policy
In nuclear physics, spontaneous fission halflives are central in many areas, such as the study of superheavy nuclei and astrophysical nucleosynthesis. In this thesis, a new method for obtaining spontaneous fission halflives from collective coordinate energy landscapes is proposed, tested, and compared to experimental results. The new method uses the Rayleigh quotient iteration to find the time de
Population decline in rural areas is observed in almost every European country. In Croatia, there are no meaningful strategies to mitigate the consequences of depopulation. As a result, many rural communities have already disappeared, while more are becoming unsustainable. Krapina-Zagorje is a region severely impacted by the shrinking and aging of its population. This thesis approaches depopulatio
Purpose: The purpose of this research is to empirically estimate the divestiture announcement effect on the shareholder’s wealth for metal-producing companies using the event study methodology and to analyze firm and industry-specific factors that can affect/cause these announcement effects by implying the cross-sectional analysis. Data Selection: Research sample contains information regarding d

The aim of this master’s thesis is to increase knowledge about how Swedish research libraries work with special collections, in aspects of preservation and user availability. Currently there is no general regulation in Swedish law regarding special collections, which may cause inconsistency in the management of collections. In order to illustrate this problem, and investigate what commission resea
Arbetsmiljöverket (2015) uppmärksammar i sin rapport problematik gällande bland annat återhämtning och att ständigt vara tillgänglig. Denna studie ämnade att undersöka om intern återhämtning kunde predicera arbetstillfredsställelse, för individer inom sälj- och serviceyrken. Vi undersökte också upplevelsen till möjligheter till intern återhämtning. En mixad metod användes och 130 stycken individerIn a report from 2015, Arbetsmiljöverket draws attention to issues concerning recovery and being constantly available. This study aimed to investigate whether internal recovery could predict job satisfaction, for individuals in the sales- and service professions. We also examined the experience of opportunities for internal recovery. A mixed method was used and 130 individuals answered an internet
Despite that transports contribute to around a quarter of all global energy-related CO2 emissions, the question of how the sector’s emissions are best reduced remains unclear. To fill this gap, this thesis investigates what both academia and the Swedish Climate Policy Council recommend to be the best ways of reducing transport emissions. These findings are then compared with the mobility strategie
Proteoglycans are important macromolecules located on the human cell surfaces. They have many different and important roles in communication between cells. These roles are especially important for cancer development and the survival of tumor cells and these proteoglycans are, therefore, interesting to study. The proteoglycans are made up of a protein core to which glycosaminoglycan chains are boun

Can Construction Management (CM) achieve the right price and quality in a time and cost-effective way? Construction Management is a form of a project delivery method that may occur under different types of construction contracts. The purpose of this survey is to identify the strengths and weaknesses
