The implementation of peer-to-peer in flash crowds: A case study of bandwidth and cost reduction for over-the-air updates

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

Does policy adoption influence the association between socio-economic differences and smoking prevalence? A longitudinal analysis 2008-2015

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:

The User Experience Perspective of Internet of Things Development

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

The thesis is b

The Relationship between Fiscal Federalism and CO2 emissions in China

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

Niche management of Autonomous Vehicles for positive environmental outcomes in Copenhagen

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

Balansen mellan integritet och kontraterrorism - Svensk tillämpning av Dataskyddsdirektivet utifrån ett realistiskt perspektiv

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

De gåendes värde i den moderna staden - kunskapsöversikt och empiri

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.

Detecting Impersonation Attacks in a Static WSN

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

Intellectual property rights in purchasing and sourcing - Overview of current best practices

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
