Simulation and data analysis of peer-to-peer traffic for live video streaming

Evaluating and testing changes or configurations to peer-to-peer systems or even understanding their behaviour can be complicated. One approach is to simulate a large peer-to-peer system and visualise the results. In this master's thesis a study is performed to understand how an actual implementation of a hybrid peer-to-peer live video streaming system behaves and performs under different scen

Integration of a Digital Built-in Self-Test for On-Chip Memories

The ability of testing on-chip circuitry is extremely essential to ASIC implemen- tations today. However, providing functional tests and verification for on-chip (embedded) memories always poses a huge number of challenges to the designer. Therefore, a co-existing automated built-in self-test block with the Design Under Test (DUT) seems crucial to provide comprehensive, efficient and robust testi

American Dream Turns to Nightmare: The Decline of the United States Middle Class

The United States middle class has become a major topic of discussion and debate over the past several years, playing an intricate part in economic and political policies today. The reasoning behind this is due to the acknowledgement of the average American household struggling to maintain their standard of living with rising costs of goods and services along with stagnating wages. Unemployment is

Efterarv och försäkring - Kan ett förmånstagarförordnande skapa ett efterarv?

Då en make ärver en make med släktingar i första eller andra parantelen uppstår arvsrättsligt en efterarvsrätt. Denna efterarvsrätt har tidigare inte förtydligat huruvida en försäkringsersättning som utfaller genom förmånstagarförordnande till efterlevande make ska inräknas i efterarvet. 1975 kom ett rättsfall från högsta domstolen som fastställde just detta, att det faktiskt föreligger rätt till When a spouse inherits another spouse, who has children from a previous marriage, parents, siblings or nephews alive, a right to secondary inheritance occurs according to Swedish law. Before 1975, it was not clarified whether this right to secondary inheritance should include an insurance reimburse-ment due to an insurance with a spouse as beneficiary. In 1975 the Swedish Supreme Court ruled that

Benefits and risks of implementing a dynamic shelf life prediction system

Matsvinn är ett problem med miljömässiga, ekonomiska och sociala konsekvenser. Nära en tredjedel av maten som produceras i världen idag kastas eller förstörs, något som är ohållbart av en mängd anledningar. Ett forskningsprojekt som drivs för att åtgärda detta är DynahMat-projektet på Lunds Universitet. DynahMat föreslår användandet av temperaturindikatorer och andra sensorer för att beräkna en prFood waste is a problem with environmental, economic and societal aspects. Up to a third of global food production is wasted every year, something that is unsustainable in many ways. Much research is currently being done to alleviate the problem. The DynahMat project at Lund University proposes using temperature indicators and sensor technology to improve food supply chains and provide a more accu

Solar Block

A lot of cities today face serious problems. Some of them are not so harmful but they still have a significant impact to our surroundings. Our role as architects must be to create better environment , a better daily life for people. Mostly all of dense cities are currently facing enormous and rapid urban and population growth ,which is hard to follow in the same speed by suitable architecture shap

I denna studie undersöks demokratibistånd och under vilka förutsättningar det kan generera demokratiska och ekonomiska effekter i mottagarlandet genom en deskriptiv litteraturöversikt av moderna forskningsresultat. Förutsättningar hos både givarparten och mottagarlandet tas upp för diskussion. Studien går sedan vidare med en fallstudie av Moçambique. I fallstudien undersöks hur förutsättningarna v

Playa och Prekaritet - En kvalitativ studie om europeiska callcenterarbetare i Barcelona

Syftet med denna studie är att ur ett sociologiskt perspektiv undersöka hur det är att bo i Barcelona och arbeta i ett internationellt callcenter som ung europeisk medborgare. Vad är det som motiverar individer att migrera och arbeta i Barcelona? Hur upplever de förutsättningar i arbetet, social gemenskap och hur uppfattar de sin tillhörighet? Dessa frågeställningar sätts sedan i en bredare kontexThe aim of this study is from a sociological perspective understand how it is to live in Barcelona while working in an international call centre as a young European citizen. What motivates these individuals to migrate to Barcelona? What is their perspective of work, social community and notion of belonging? These questions are later to be examined together with theories of migration, modernization

Feedforward neural networks with ReLU activation functions are linear splines

In this thesis the approximation properties of feedforward articial neural networks with one hidden layer and ReLU activation functions are examined. It is shown that functions of these kind are linear splines and the number of spline knots depend on the number of nodes in the network. In fact an upper bound can be derived for the number of knots. Furthermore, the positioning of the knots depend o

Electrical Characterization of GaN Device Structures and Coalesced Films

Wide band gap semiconductors such as gallium nitride (GaN) are attractive candidates for short wavelength optoelectronic devices and high-power/high-temperature electronics. Widespread commercial adoption has been hindered by great difficulties encountered in obtaining high-quality materials. No suitable substrate material is available, making lattice matching unattainable and resulting in high th

Does repetition make perfect? Comparing scanpaths over repeated visual search to investigate how scanpath similarity evolves with experience

Visual search efficiency improves with repeated exposure to the same search problem, yet the mechanisms behind these search efficiency gains remain unclear. Investigating how eye-movement sequences evolve over repeated viewings is fundamental for understanding how skilful search develops over time and its role in learning and gaining expertise. Scanpath theory holds that repeated displays are inve

Internationella kvinnodagen…med mannen i fokus? En kvantitativ och kvalitativ studie om porträttering av kvinnan och mannen i svensk dagspress.

The purpose of this thesis is to study how femininity and masculinity are portraited in three Swedish national newspapers (Aftonbladet, Svenska Dagbladet and Dagens Nyheter), which all represent different points on the Swedish ideological spectrum. The focus of the studie was to answer how women and men are portraited with stereotypical traits, if there is similarities and differences and how the

”Men i mitt hemland blir jag kallad för svensk … Sån ironi …” - en kvalitativ studie om hur kosovoalbaner förhåller sig till sin identitet

Inom identitetsforskning finns det olika definitioner av identitet. För att få en djupare förståelse för begreppet identitet, har jag valt att undersöka hur kosovoalbaner förhåller sig till sin identitet i ett svenskt samhälle. De empiriska uppgifterna samlades in genom kvalitativa semi-strukturerade intervjuer. Min analys baserades på begreppen identitet, tillhörighet och kultur. Baserat på det e

Is the medium really the message?

Den digitala utvecklingens framfart, liksom globaliseringens många påföljder, banar inte bara väg för otroliga möjligheter utan sätter även en ständig press på moderna och internationellt etablerade företag. Inre såväl som yttre slitningar kan dock lätt uppstå när en ständigt accelererande utveckling forcerar fram förändringar. I samband med förändring väcks frågan om det råder en övertro till tek

Future offshore wind farm construction and maintenance strategies

With the wind farms moving further from shore, new challenges arise. Technicians must visit the turbines almost daily because of the constant need for maintenance. But when the transport time from shore to the wind farm turns into hours is some kind of permanent accommodation required at the farm for the technicians to live on. Apart fromaccommodation the deep water is a big challenge. This paper

Urban flood modelling : a GIS based approach in Lomma, Skåne region

Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. However, the implementation of these models require high-level proficiency in GIS and hydrology. Thus, man

Introduction and Proof of the Goodstein Sequence and Hydra Game

This thesis will introduce and prove the theorem of the Hydra Game as well as the theorem surrounding the Goodstein sequence. The two problems which are clearly intertwined will be introduced and solved with the assumption that the reader has no previous knowledge of them and little to no knowledge of ordinal numbers. All results have previusly been reached and presented, most notably by Kirby and

Self-modelling organizer for interior storage

Today's urbanization creates big cities. More and more people are facing the problem with the increasing housing prices, and they had often to live in small or shared apartments. Most of the kitchens in those apartments are often small, which leads to a increasing need to use the available space in a more efficient way. An investigation conducted for the existing solutions in the market, has r
