Network cameras has in the recent years become more powerful. Each camera is independent and has its own surveillance task. It is reasonable that network cameras in the future should cooperate together to increase surveillance effectiveness. There is a need to find cameras sharing the same field of view in order for an operator to switch perspective. This thesis investigates how multiple network c
This thesis uses the principal-agent theory to analyse two interconnected problems within the Japan’s renewable energy sector, namely the Feed-in Tariff (FIT) policy, and the energy grid issue. Following the Fukushima accident, while the nuclear power plants remained closed, Japan’s renewable energy sector was able to experience enormous growth. The number of applicants for the FIT was greater tha
In this thesis the WKB-approximation is used to simulate the tunneling current for an Esaki nanowire diode and the result is compared to data from Esaki nanowire diodes grown with MOVPE. The WKB-approximation with triangular potential barrier predicts a strong increase of the tunneling current as a function of the doping densities and at the highest doping levels it gives lower tunneling distances
Kommunernas arbete för att ta hand om dagvattnet är intressant då klimatanpassning har uppmärksammats på en nationell nivå. Parallellt arbetar många skånska kommuner för en förtätning av den bebyggda miljön. Utmaningen med förtätning ligger i att ju mer bebyggelse och infrastruktur det byggs desto mindre ytor för infiltration lämnas kvar och desto större tryck skapas på det befintliga va-nätet närMany municipalities plan for urban infill development to fulfill the housing needs and diminish urban sprawl. Without a good planning approach, urban infill brings more impervious areas and smaller green areas that can take care of stormwater. This creates pressure on the existing drainage system when heavy rains fall. Thus, there is a risk for urban flooding if those aspects are not taken into co
Volvo Construction Equipment are investigating new machine concept that involve fast charging with high power. This should be done automatically and independent on humans. The thesis set out to develop and design a complete system solution for this, including the connector and the automated system for connection. The thesis is based on previous projects presented at LTH in various mechatronics cou
Brain activation mapping using fMRI data has been mostly focused on finding detections in gray matter. Activations in white matter are harder to detect due to anatomical differences between both tissue types, which are rarely acknowledged in experimental design. However, recent publications have started to show evidence for the possibility of detecting meaningful activations in white matter. The s
Current ripple can cause a lot of problems as it spreads in the DC-side of the TVS of electric and electric hybrid vehicles. Fully knowing the properties of the TVS can be used to build a simulation model to determine the spreading of current ripple beforehand, which in turn is useful for calculating component placement, optimal filter sizes, and component lifetime. Being the second in line of an
Idag är det många äldre flerbostadshus som står inför behov av renovering och energieffektivisering. Äldre byggnader har en betydligt högre energianvändning, för uppvärmning och varmvatten, än dagen nybyggda byggnader. Uppvärmningen av lokaler och bostäder svarade år 2014 för ungefär 35 procent av den totala energianvändningen. I kombination av en ökad urbanisering och ett renoveringsbehov av äldr
Cameras mounted on boats and in other similar environments can be hard to use if waves and wind cause unwanted motions of the camera which disturbs the desired image. However, this is a problem that can be fixed by applying mechanical image stabilization which is the goal of this thesis. The mechanical image stabilization is achieved by controlling two stepper motors in a pan-tilt-zoom (PTZ) camer
Background: Capsaicinoids are the compounds responsible for the pungent taste in the chili pepper genus capsicum. They are potent agonists of TRPV-receptors have large potential to be used as pharmaceutical agents for the treatment of various disease conditions associated to the peripheral and central nervous systems. Capsaicinoids are synthesized by the acylation of the aromatic compound vanillyl
Until now we still depend on oil and natural gas to supply us with fuels and other chemicals as a foundation to our economic advance. The global population is expected to reach 9 billion by 2050. With increasing population, the oil resource consumption will also increase, and an alternative source must be found and developed to supply us with chemicals and fuel needed for our economical advances,
Genetics for Manganese Manganese (Mn) is one of the essential minerals for humans and it is mainly present in blood, liver, intestine, and brain. However, at elevated concentrations, for example from occupational or environmental exposure, Mn may be toxic to the nervous system. Despite that Mn concentrations are tightly regulated in the body, concentrations seem to depend on our genetics. The ai
”How to win the war outside of the battlefield in ancient Greece and Rome – the generals explain” The purpose of this thesis is to shed some light on the topic of psychological warfare in two ancient, war-describing texts: The History of the Peloponnesian War, written by Thucydides, and The Commentaries on the Gallic War, written by Julius Caesar. The main reason behind this lays in modern approa
This study aims to give an overview of how nation branding is organised in the Netherlands by analysing the collaboration of individual institutions involved in nation branding and the so called ‘Holland Branding Collective’. Nation branding in the Netherlands is a fragmented field where institutions approach nation branding bottom-up with a combination of public and private actors. There are seve
The use of Electronic Flight Bags (EFBs) have become widespread and common among a majority of commercial airlines in Scandinavia and the United States in recent years. This development was enabled by modernized rules and regulations and the availability of suitable and affordable commercial-off-the-shelf (COTS) devices. This bachelor thesis studied EFB usage and user experience among pilots in com
Threat and Error Management (TEM) har framförts som en modell för att förstå, förklara och utbilda i hur olika flygsäkerhetsrisker uppkommer och kan hanteras för att uppnå en ökad flygsäkerhet. Den bygger till stor del på den tidigare utvecklade modellen för övervakning av operationell flygverksamhet, Line Operations Safety Audit (LOSA). Information har insamlats med hjälp av litteraturstudier, in
Denna uppsats syftar till att undersöka det så kallade parodiundantaget. Det upphovsrättsliga fenomenet innebär att ett bearbetat konstverk, i syfte att vara en parodi, faller utanför den ursprungliga upphovsrätten. Detta eftersom bearbetningen i egenskap av en komedibetonad prägel innehar ett i förhållande till sin förebild främmande innehåll och är därmed att anses som ett nytt och självständigtThis essay aims to investigate the so-called parody exception. The copyright phenomenon means that a processed artwork, in the purpose of being a parody falls outside the original copyright. Because of its form of parody, the processed artwork holds a foreign content in relation to the original and is thus considered a new and independent artwork, regardless of the copyright of the original. For s
The aim of this study is to do a qualitative research on the campaign Stop the Trucks. My methods include visual analysis of the campaign film and website, text analysis of the press release and interviews with three animal welfare organizations that were all part of the campaign. I will use a social constructionist perspective to depict how our moral view of non-human animals is socially construc
Avhandlingen syftar till att undersöka om det är mjöligt att finna billiga approximationer till extremvärdena för kvadratiska former. Dessa extremvärden kan t.ex. användas för feluppskattningar i tidsstegningsmetoder för lösning av differentialekvationer, men då extremvärdena måste uppdateras varje steg måste metoden vara billig. Här undersöks dessutom "stora" matriser och möjligheten atIn this thesis approximations to quadratic forms using Krylov subspaces are presented. These quantities are approximations of the norm and logarithmic norm of a matrix. In order to find these quantities an eigenvalue problem has to be solved, but because of limited storage and time, this is not feasible in practice with large matrices. Instead one can project this problem down to a problem of smal
Att spåra kunder i online-butiker har länge varit en självklarhet för branschen. Det de flesta inte vet är att det även är möjligt att spåra kunder i fysiska butiker, utan att den personliga integriteten går förlorad.Retail intelligence is a big and upcoming thing in the brick and mortar-world of retail. This simply means that the resellers want to gather as much data about their products,and possibly also their customers, as possible. Some stores might want to know different information than others, but the fact of the matter is that gathering off-line data is slowly entering the world of business. There are
