The current field of object detection and image recognition is huge but not without complications. Processing large amounts of high resolution videos needs powerful hardware and also risks breaching the privacy of those who are recorded. In times of increasing demand for decentralized solutions and stricter privacy protection regulations being put in place a new approach is needed. We present an
Bananpiren means the Banana pier and the name is a remnant from when ships full of bananas unloaded by the docks. The last banana ship left the wharf in the year of 2000 and since then the pier has mainly been used for different types of temporary events. Apart from when those are held, the pier is abandon with only one sheet shed still standing, as a glimpse of the piers former past as a freeport
I denna uppsats ser vi vad som händer när en statlig myndighet som ansvarar för utformning av offentlig miljö implementerar en så kallad liberal demokratiteori. Statens konstråd, som är en myndighet med stor inverkan på den offentliga konsten i Sverige, inledde 2012 ett nytt arbetssätt att föra ut konceptuell och samtida konst från institutioner och gallerier till det offentliga rummet. Deras syn
Climate change is a problem. The power sector will bear the brunt of decarbonisation. The most cost effective pathways of achieving deep decarbonisation involve a diverse portfolio of energy technologies. A considerable body of theory suggests that the composition of finance can influence not only the rate but the direction of technical change by selecting technologies with certain economic charac
Plastics play a central role in todays society and its use will only increase. When certain plastics are broken down to a nanometre size they become toxic to some aquatic life. Such plastic particles often undergo aggregation, especially in the aquatic environment. It is therefore of interest to study how different types of aggregation affects the physical characteristics as well as the toxicity o
This study examines minimally altered catchments in Europe and North America in order to determine whether any changes to the dynamics of flooding have occurred due to changes in the climate. By examining the parameters of the Generalized Extreme Value (GEV) distributions of individual catchments it is possible to determine not just if changes in flood patterns have occurred, but also the nature o
Eukaryotic cells employ the RNA interference (RNAi) machinery in the cytosol to downregulate gene expression. Short 21-nucleotide microRNAs (miRNAs) associate with the so-called RNA induced silencing complex (RISC) and hybridize with the target gene’s mRNA, preventing it from being translated into protein. Employing the RNAi machinery with synthetic small interfering RNAs (siRNAs) that mimics the
The last few years have seen a rapid expansion within the area of the Internet ofThings (IoT). For many IoT applications, such as asset tracking and distributedsensor networks, the problem of localization (i.e. determining the physical loca-tion of nodes in the network) is fundamental. For such applications, constraintson size, cost, and power consumption often prohibit the use of GPS. This thesis
With the ongoing climate collapse, there is a need for a capital switch, rerouting investments into low carbon infrastructure. Green bonds are a new financial vehicle aimed to facilitate this transition. Through signaling the issuers’ intent to use the proceeds of the bonds towards environmentally beneficial activities, they increase transparency and allow investors to better calculate risks while
Att studera språket och dess metaforer kan säga mycket om hur vi tänker kring en företeelse. I min undersökning tittar jag, dels genom en metaforanalys, dels genom en enkätundersökning, på hur resemetaforen framställer den som är sjuk i cancer, och hur den sjuke reagerar på denna framställning. Syftet med studien är att undersöka vilka konceptualiseringar av cancern som kommer till uttryck i infor
Natural killer cells are part of the immune system and one of their main functions is to dispose of cancer cells and virus-infected cells. In order to avoid detection by T cells, cancer cells can decrease the expression of MHC I proteins which instead can make them a target for NK cells, making NK cells a suitable for use in therapy. This study sought to investigate the cytotoxic ability of NK cel
Syftet med studien var att undersöka anorektiska patienters upplevelse av tvångsvård enligt LPT (Lagen om psykiatrisk tvångsvård) utifrån en psykologisk ram, för att nå fördjupad förståelse för deras erfarenheter. Semistrukturerade intervjuer genomfördes med elva deltagare. Det insamlade materialet analyserades med en tematisk analys och nio teman gick att urskilja. Studiens centrala slutsatser vaThe aim of this study was to explore anorexic patients' experiences of compulsory treatment within a psychological frame, to gain a deeper understanding of their experience. Semistructured interviews were applied with eleven persons. Thematic analysis was implemented to analyse the collected data, which allowed the authors to distinguish nine different themes. The main results of the study ind
Metaforer är ett viktigt inslag i det psykoterapeutiska samtalet och en språklig och mellanmänsklig egenhet som är av stor betydelse för det psykoterapeutiska arbetet. Syftet med denna studie är att undersöka hur psykoterapeuter förstår och använder metaforer som ett verktyg i sitt dagliga arbete. Undersökningen bygger på intervjuer med fem psykodynamiska psykoterapeuter med olika lång erfarenhet Metaphors are an important part of the psychotherapeutic conversation. They represent an interpersonal linguistic element that are of major importance for the psychotherapeutic work. The purpose of this study is to investigate how psychotherapists understand and use metaphors as a tool in their daily work. The survey is based on interviews with five psychodynamic psychotherapists with different de
Food production accounts for some of the most significant social and environmental impacts at global scale. Reliable information on who produced a product where and under what conditions is a critical enabler for meaningful action on some of the most pressing challenges. Third party certification and labelling remain widely used tools to identify sustainably produced commodities. Fragmented auditi
Artificial Neural Networks (ANNs) are widely used information processing algorithms based roughly on biological neural networks. These networks can be trained to find complex patterns in datasets and to produce certain output signals given a set of input signals. A key element of ANNs are their so-called activation functions, which control the signal strengths between the artificial neurons in a n
In Ecuador, more than 85% of electricity production relies on hydropower and consequently the supply of electricity relies on water availability. During the dry season (October-March) hydropower capacity could diminish up to one-third of its installed capacity or more under a severe drought causing a substantial augmentation of thermoelectric power output to offset the lack of hydropower to cover
FORMOX™ is a formaldehyde production process, utilizing a metal oxide catalysts. The new generation of plants is pressurized, therefore the turbo charger concept has been developed. This concept deploys a turbine coupled to a compressor, where the turbine recovers a substantial part of the electric power needed to run the compressor, from the outlet of the emission control system unit (ECS) in the
The purpose of this project was to investigate how the interior of a future autonomous truck can be designed with a user friendly focus. The solution should be suitable for a future scenario in 2030 where a Volvo FH with automation level 4 on the SAE scale will drive the route from Gothenburg to Umeå. This means that the truck is fully autonomous but there has to be a driver in the cab that can dr
In this thesis a robot-held platform is developed. The final goal of the platform is to follow a potential surgeon’s head during operation while cameras mounted on the platform film the ongoing operation from the perspective of the surgeon. In this thesis the original concept developed by Emma Andersson and Anna Wikström is developed further by extending the design to allow placement of sensors an
