This thesis is a general overlook on the societal benefits of walking infrastructure. It is divided between a literature review; concerning what makes people walk, what benefits this might give and how to place a value on these factors, and an empirical part; researching how evaluating value, and by other means quantifying effects, is used and can be used in the planning of walking infrastructure.

The current state of security found in the IoT domain is highly flawed, a major problem being that the cryptographic keys used for authentication can be easily extracted and thus enable a myriad of impersonation attacks. In this MSc thesis a study is done of an authentication mechanism called device fingerprinting. It is a mechanism which can derive the identity of a device without relying on device

In purchasing and sourcing situations not all companies have a guideline or policy on the handling of intellectual property (IP) rights in these. This thesis covers a literature study on the area followed by interviews with high ranking positions in the industry and technology sector. The aim of the thesis is to create an overview of current best practices in said situations. By consulting relevan

Kalibreringsananlys​ ​av​ ​akustofores​ ​i​ ​mikrokanal Varje år blir miljontals människor diagnostiserade med cancer och det arbetas intensivt med att hitta behandlingar och mediciner för detta genom att undersöka hur cancer fungerar. Då är det även viktigt att man vid forskningen kan lita på sina resultat. I ett av forskningsområdena används ljud för att flytta celler i en kanal, kallat akustofAcoustophoresis has proven to be a promising technique when it comes to separation of particles or cells in a microchip. One of the main areas of interest is the separation of so called circulating tumor cells (CTCs) from whole blood - which could serve as an indication of early stage cancer or in general be studied in order to obtain more information about these cells. However, one issue with th

In this study it is examined whether the amount of Foreign Direct Investments (FDI) is affected by terrorism in three developed countries in Europe from a time series approach. The countries that are examined are France, Spain and the United Kingdom. The time period is 1975-2016 and the observations are annual. In previous literature there is evidence that terrorism should have an impact on FDI. F

Iceland is an island located in the North Atlantic Ocean where the climate is cold and the weather can be unpredictable. The sun angle is low during winter, which gives minimum daylight. This darkness and strong winds affect the urban life in the capital city Reykjavík and controls how people commute and spend their free time. One of the main goals in the regional plan for the capital area is to

At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater p

The telecommunication industry contributes to environmental impacts through energy usage and material resource use. The incorporation of Circular Economy strategies has the potential to restructure and re-engineer systems like those in the telecommunication industry to capture more value for the business while decreasing environmental impacts of business. The objective of the research in this pape

Uppsatsen har sin utgångspunkt i e pågående debatt om hedersvåld. Studiens syfte är utifrån kvalitativ innehållsanalys undersöka förebyggande metoder mot hedersrelaterat våld och förtryck. Uppsats har sin utgångspunkt i: Genusteori, Bourdieu´s teori om manlig dominans, hedersbegreppet och om kulturbegreppet. Det empiriska materialet har samlats in från Länsstyrelsen Östergötland i form av handböck

In the following years we will experience a transition towards Internet Protocol version 6 (IPv6). The reason is the depletion of IPv4 address space due to the rapid increasing numbers of Internet of Things (IoT) devices connection. This transition however poses a problem, since the majority of these devices mostly are mobile and not connected to power source. Neighbor Discovery Protocol (NDP) def

In 1964, a theory was presented on how an invisible field is acting in nature, which causes mass to arise. The theory gives an explanation of how something can come from nothing and thus takes humanity one step closer to understanding how the universe works. Proving the theory was problematized by the fact that no experiments could be conducted since particle accelerators at the time weren't p

Metacognition is necessary for learning. Without know-ing what you know, what you don’t know and what you are about to learn, seeking new knowledge becomes both hard and inefficient. At the same time, keeping old facts (as well as old skills) in mind at a meta-level when striv-ing for new insights is not always an easy task. Conse-quently, external visible cues and representations are essential, r

Översvämningar och vattenföroreningar är kopplade till försummelse av vattenhantering vid hastig urban utveckling. Om tre decennier förväntas 66% av jordens befolkning bo i städer. Hur löser vi detta? Idag bor nästan hälften av jordens befolkning i städer – en siffra som förväntas öka till mer än fem miljarder personer fram till 2030. Urbanisering anses ha stor positiv påverkan på ekonomisk tillvDue to internal conflicts and an economical conversion in the mid 1900’s, the Colombian society has seen a great social transition from rural to urbanised in the last 50 years. Apart from positive impacts of urbanisation on social factors, there are hydrological issues coupled to it. With the aim to assess the impact of urbanisation on runoff peak flows in Bogota, the historical change in impervio

Tidigare studier indikerar att ooider har förutsättningar att användas som naturliga arkiv för att undersöka variationer i oceankemin samt klimatförändringar som sträcker sig hundratals år tillbaks. Ooider är sfäriska eller ellipsoidformade karbonatkorn med en medelstorlek mellan 0.25 och 2 millimeter. Ooidens struktur kan variera, men gemensamt för dem är att de utgörs av en kärna som kan vara en

Bakgrund: På grund av den höga invandringen av immigranter till Sverige från Mellanöstern och Västasien har antalet migrerade kvinnor blivit allt flera. Kvinnor som både lider av fysiska och psykiska funktionsnedsättningar har ofta svårt att anpassa sig till den nya kulturen där kulturella värderingar skapar problem i vardagen. Idag finns det ganska få studier som handlar om första-generationens i

Background: Colorectal cancer constitutes a major malignancy and the fourth major cause of deaths associated with cancer. Chronic inflammatory bowel diseases like Crohn´s disease and ulcerative colitis are one of the risk factors for the development of CRC. Cysteinyl leukotrienes (CysLTs) regulate both acute and chronic inflammation through lipophilic signaling. Upregulation of the expression of C

Today, one of the main economic engines is construction field. A few periods of history showed that in Lithuania, the main goal for the companies were to build fast, cheap dwellings on the empty lots. The capital of Lithuania, Vilnius city is not an exception. City is built ineffectively. Functions, neighbourhoods are far apart from each other and the transportation ineffectiveness leads to the lo

The Differentiated Services (DiffServ) Architecture, a Quality of Service (QoS) solution being worked on by an IETF work group, is aimed to solve the increasing problems with no service guarantees in the current Internet. New services such as video-on-demand and IP-telephony will be unusable without some sort of service guarantees on which to build applications on. A replacement architecture for t

The aim of this report was to study possibilities of making the process of extracting lignin from black liquor at pulp and paper mills more efficient in the form of a literature study. Lignin is a commodity that is likely to become more valuable in the future due to work being done by a number of companies in utilizing it as for example a base for the production of renewable fuels and carbon fibre
