Product quality is a major concern for all companies. Predicting the lifetime return rate allows for identification of products with atypically high return rates. Such products might otherwise not have been detected before it is too late to take any action to reduce the return rate. Furthermore, predicting a product’s return rate allows for estimation of the company’s expected cost of handling ret

This thesis will examine the plausibility of exchanging protocol from a normal server-client to a peer-to-peer solution for over-the-air updates, using a single case study for Sony Mobile Communications AB in Lund, Sweden. It will examine the effort, the risks, and what the actual gain may be comparing to a client-server approach for over-the-air software updates. Sony Mobile today uses a content

Abstract Introduction: Smoking is a major public health concern, accounting for nearly 700,000 deaths on an annual basis, globally. The socio-economic differences within smoking are well established, reflected in a social gradient that is estimated to account for half of the socio- economic differences in mortality for men aged 35-69 years in developed settings, such as the European region. Aim:

Inom nuvarande forskning om Internet of Things (IoT) finns det inte många studier som har tittat på användarperspektivet eller på hur företag som är verksamma inom IoT avväger användarupplevelse när de utvecklar IoT-produkter. Syftet med denna studie är att undersöka hur användarupplevelsen tas hänsyn till under utvecklingsprocessen för IoT. Den syftar också till att undersöka i vilken utsträckninIn current research of Internet of Things (IoT), there is limited research on the user perspective and even less on how companies operating in the field consider User Experience (UX) when developing for IoT. The aim of this thesis is to investigate how UX is considered during the development process of IoT. It also includes exploring to which extent this is done with a data-driven approach. The st

This paper focuses on description and analysis of the management control systems (MCSs) in different startup companies. The qualitative study with an exploratory approach was chosen. In order to identify factors that affect MCSs in the startups, and examine actual impact on the design of MCS in these companies, interviews have been conducted with three Swedish firms, selected from the group of com

In this master thesis the consistent initialization problem is studied and three different algorithms were developed regarding the subject area - a graph algorithm used for solving the initialization problem, a parallel algorithm to enable parallel computations when solving the initialization problem and lastly a genetic algorithm used as a preprocessing stage for parallelization. The thesis is b

The decentralization of fiscal responsibilities in China has strengthened economic development and enhanced local public management. However, due to fiscal competition, local governments that are fiscally constrained tend to neglect environmental standards in favour of economic growth. This study researches how outcomes of fiscal federalism in China, measured by budgetary ratios of gross regional

Cities around the world are leading the race toward an environmentally sustainable future, but one of their major obstacles have been the personal automobile. The movement of people using public transportation often has a far lower impact than the personal automobile, but these systems are often rigid and expensive to build and operator. Now, with the emergence of intelligent transport systems – a

Det europeiska Dataskyddsdirektivet avser bland annat att skydda enskilda individers integritet vid brottsbekämpande och behöriga myndigheters behandling av personuppgifter. Genom att uppmärksamma svensk tillämpning av Dataskyddsdirektivet vill jag belysa balansen mellan integritet och kontraterrorism. Jag har valt realism som teoretisk utgångspunkt då realism kan förklara staters intressen. Det i

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
