Uttrycket “övervakningssamhälle” är något som det talas om mer och mer. Vilket inte är så konstigt då många allmänna platser ofta är övervakade med antingen film eller ljudupptagning. Att kunna identifiera individer som på något sätt har brutit mot lagen eller förutse oönskade situationer är något som stärker vår säkerhet och ordningen i samhället. I många länder ses detta som helt nödvändigt och This report describes the product development process of a new product series of camera housings, adapted for modular applications. The purpose of the project was to develop a module containing a wiper, adapted for outdoor camera housings. The master thesis was performed at Axis Communications AB, a leading company in the surveillance camera industry. The camera housings of outdoor surveillance ca

När byggnader och broar ska dimensioneras är det viktigt att knutpunkterna för konstruktionen är noggrant beräknade. För att utföra beräkningar som tar hänsyn till knäckning och andra fenomen används ofta datorberäkningar i viss utsträckning. Det tar ofta oerhört lång tid, både för användaren att skapa en modell för konstruktionen i den grad av detalj som behövs, samt för datorprogrammet att beräkWhen designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. For most projects it is not reasonable to analyze a complete structure in exact detail and therefore simplified methods are used

Inventory control is a subject that impacts more or less every section of most businesses, hence companies today view it as a crucial problem of strategic importance (Axsäter, 2015). Managing inventory is a complex task which can be made even more complex by considering multiple items interacting with each other throughout the supply network. This master thesis attempts to show, through a case stu

In wireless communication, resources like bandwidth and energy are scarce and extremely valuable, any system should serve as many users as possible while preserving high Quality of Service (QoS) for the best user experience. Accordingly, the Base Station (BS) has the responsibility to optimally schedule its resources to the users based on the available information. Consequently, the whole process

This project investigates what human interaction is and how we collaborate within the confines of finite resources. The project ex- amines what could be done to minimise the need of ownership and instead reconnect the human to the collective by encourag- ing sharing. The method used to achieve this will be an in-depth design process. The investigation is conducted from the stand point of a Swe

Studiens syfte är att få fram hur FN ser på sexuella övergrepp som utförs av deras egen personal. Jag har utfört en diskursanalys utifrån frågeställningarna om det pågår ett förebyggande arbete inom FN för att stoppa sexuella övergrepp och hur FN talar om övergreppen och förövarna. Teorin jag använder mig av är R. W. Connells teori om maskulinitet som utgår från tre relationstyper och fyra maskuli

Probiotics are living microorganisms which could induce a potential health benefit to the host when consumed in adequate amounts. Among the different probiotics in the market, Lactobacillus reuteri strain DSM 17938 is a microaerophilic and heterofermentative organism that is able to tolerate high oxygen conditions compared with another L. reuteri and lactic acid bacteria strains. This study invest

Antibiotika är en av de viktigaste upptäckterna under 1900-talet. Med antibiotika blev det möjligt att bekämpa och förhindra bakteriella infektioner. Ett växande och svårlöst problem är antibiotikaresistans. Detta projekt syftar till att hitta alternativ till klassisk antibiotika. Vi har arbetat med sialinsyra, en kolhydrat som återfinns på cellytan. De flesta bakterier tillverkar inte själva siaThe development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl

Today, 55 percent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 percent by 2050. The cities are growing, densifying and expanding. On the dark side of urbanization and rapid growth, the city centres work as dense machineries for businesses, commerce, automobiles and computerization. As a result, significant numbers of urban citizens are experienc

The literature suggests that executives still doubt the real contribution of HR, and one reason for this is that it is difficult to measure the Return on Investment in HR activities. In addition to this, earlier studies on the value creation of IT seems to discount the intangible value creation that IT investments bring to organizations. The purpose of this thesis is to investigate and compare how

This thesis is about predicting the average ten minute closing bid price of the USD/SEK exchange rate by applying deep learning methods. First, the time lag method is applied for the vanilla Feedforward Neural Network (FNN) to undertake one-step prediction. Secondly, three univariate Long Short-Term Memory (LSTM) models are used to undertake one-step and multi-step prediction. Each network is theo

Exposure to skin sensitizers on a daily basis has been leading to a high prevalence of allergic contact dermatitis (ACD) among the general population. Single substances have been thoroughly studied for their skin sensitizing potential, yet little is known about the cellular mechanisms of so-called “cocktail effects” of mixtures. It has been suggested that induction of oxidative stress, and more re

Bestämning av värmeledningsförmågan i nano-grafit Kunskap om de termiska egenskaperna hos nano-grafit (väldigt små grafitmaterial) är avgörande för att förverkliga de många lovande tillämpningarna av kolbaserade nanomaterial. För att bestämma värmeledningsförmågan i nano-grafit har tunna grafit filmer undersökts vid MAX IV-laboratoriet. Genom att undersöka hur värme förflyttas i materialet visadKnowledge about thermal properties of nanoscale graphite is essential in order to realize the many promising applications of carbon based nanomaterials. This thesis reports how samples of thin graphite films on nickel substrates were investigated using time-resolved X-ray diffraction (TRXD) at the FemtoMAX beamline at the MAX IV facility. Through these investigations the thermal conductivity of th

What goes into the development and production of a modern backpack for off- piste skiing? How is a backpack made and what is right now requested on the market? A skiers backpack is a project about making a new off-piste skiing backpack for the Swedish brand Fjällräven. It combines the values of the Swedish brand with my own thoughts about how a product like this should be and function. Th

The social and environmental impacts associated with corporate water use and discharge in Kazakhstan is historically high, and in certain watershed pose a significant threat to the health of the local communities and ecosystems. Today the industries are consuming almost a third of freshwater and remain one of the biggest polluters in the country. The situation is aggravated with the changing clima

In recent years, the global problem of plastic waste has received increasing attention. Plastic waste is frequently traded good and is often exported to countries which mismanage large proportions of their waste. By investigating Germany’s imports and exports to a selection of countries this study finds that the German recycling system has flaws in the area of plastic waste. Due to the fact that p

Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
