We describe the Fourier-Gauss-Laguerre and Fourier cosine series method and test them extensively in four models: Black- Scholes, Black-Scholes with discrete dividends, Heston and Bates. While both methods mostly achieve good accuracy and high computational speed, problems may arise with respect to the optimal choice of the method-specific parameters and the extension of the methods to other model
This essay is about digital addiction as a relevant mass media discourse in today’s information society. The purpose of the essay is to study this alleged digital addiction to see if it is reasonable, and then analyse how it can affect people’s relationships with technology and each other. The essay also strives to highlight the different opinions depending on generation and the discussion of digi
This master thesis is part of the development of a new industrial machine. The machine is a fully automated transplanting machine for the forest industry and will be used by nurseries around the world. Nurseries grow seedlings and sell them when they have grown enough to be planted in the ground. The machine being developed moves plants from a tray with small cells to a tray with bigger cells. Thi
Equal capacity in the activities of a production line is of great importance when a good material flow is desired. This is one of the basic ideas of the Lean philosophy, a mindset every modern company strives to follow. In a production with unequal capacity, the company might have to build up inventory to be able to meet the costumer demand. Inventory is a recognized waste in a production and a co
This thesis explores the experience of being young, Egyptian, supportive of the 2011 revolution, and active in civil society in the post-revolutionary period in Cairo and Alexandria. It draws from 5 in-depth interviews, and aims to understand the reasons behind youth’s engagement in the revolution beyond the framework of youth economic exclusion. It looks into their expectations from the revolutio
This thesis investigates word order patterns in spoken Basque for two dialects, Navarrese-Lapurdian and Gipuzkoan. The data for the analysis was elicited with stimuli pictures in an experiment in dialogue form. The 26 participants were from Hazparne (Lapurdi), Donostia, and Andoain (both Gipuzkoa). The data consists of transitive main clauses, both questions and declaratives with nominal subject a
Internet är ett stort globalt nätverk som fortsätter växa i komplexitet med nya tekniker och protokoll som utvidgar dess användbarhet och sättet vi sprider information. Trender, nyheter, videor och annan information sprider sig snabbt över världen vilket gör Internet till ett fantastiskt redskap för de användare som prenumererar på rätt informationsströmmar eller nyheter. Webläsare är en nödvändInternet is a vast digital network. Evergrowing in its complexity with frequent newly developed protocols extending the technology and changing the way we communicate and share information over the world. Trends, news, videos and other information spread quickly over the world, making web browsers an incredible tool for users who listen to the right feeds or news networks. Web browsers are a nec
Nowadays, with the increasing complexity of System-on-Chip (SoC), traditional debugging approaches are not enough in multi-core architecture systems. Hardware tracing becomes necessary for performance analysis in these systems. The problem is that the size of collected trace data through hardware-based tracing techniques is usually extremely large due to the increasing complexity of System-on-Chip
Samarbete och teamkänsla är vanliga begrepp på många arbetsplatser oavsett bransch. Aktörerna i byggbranschen är inte kända för att vara några pionjärer inom detta område utan branschen har historiskt sett snarare beskrivits som konservativ och konfliktfylld, vilket bidragit till att försämra byggbranschens rykte. En förändring håller på att ske, att olika aktörer kan jobba tillsammans för att nå
Det har visat sig att fysisk aktivitet minskar risken för en rad olika sjukdomar. Studien syftade till att undersöka fysisk aktivitet i olika kontexter och på olika nivåer för att bidra med ny kunskap om eventuella hälsofördelar med fysisk aktivitet. Då det är betydelsefullt för organisationens effektivitet och produktivitet att de anställda mår bra är det också viktigt att organisationen arbetar Physical activity has been shown to reduce the risk of several illnesses. The study aimed to investigate physical activity in different contexts and on different levels to contribute with new knowledge about possible health benefits linked to physical activity. Since the health of the employees is crucial for the organization’s efficiency and productivity it is important that organizations promote
This thesis reconnoiters the involvement of immigrants as owners, producers and organizers of multiethnic business ventures that appeal outside visitors, so called ethnic tourist-based entrepreneurship. The study is informed by the principles underlying an interpretive case study conducted in Rosengård, Malmö, and the data were collected through semi-structured interviews complemented by participa
This report analyses the need of sprinkler protection above suspended ceilings with regard to the fire classification of cables. The question formulation for this report is which ignition hazards can lead to a fire in cable ladders above suspended ceilings as well as how the fire classification of cables effect the need of sprinkler protection above suspended ceilings. The main conclusions that h
An embedded system’s software is often the backbone for a successful prod- uct. To make the system stand out from the other competitors on the mar- ket, your system must be adaptive and ready for quick updates. However, one may never truly know where your system is going to be used and how difficult it can be to access and update it. Here we show a solution that securely updates a system based upo
Sjölunda avloppsreningsverk är ett av de största reningsverken i Sverige och tar hand om avloppsvatten från stora delar av det snabbt växande Malmö. Befolkningsökningen sätter press på verket, där vattenreningen måste förbättras för att reningsverket ska kunna ta hand om ökande volymer avloppsvatten. För att nå detta mål drivs flera förbättringsprojekt på Sjölundaverket, däribland projekt som fokuThe activated sludge process has existed for over a century and despite its age the development of new theories, methods and technologies is ongoing. Despite huge technological breakthroughs in the last decades the activated sludge process is still a very energy demanding process however, and it is possible to make significant energy savings by optimizing the aeration strategy of an activated slud
The steel company SSAB in Borlänge has five plate heat exchangers that they use to cool the process water. The water is used to cool the steel after hot rolling. The exchangers need to be cleaned sometimes because of fouling, that reduces the cooling efficiency. This results in higher energy use and higher costs in the end. The goal of this paper is to create a model of a plate heat exchanger to m
Hem och A1M – ett test på liv och död Hem är en av kroppens viktigaste hjälpar-molekyler. När hem är bundet till proteiner hjälper det cellerna att utvinna energi och rensa ut gifter. Det mesta hemet finns i de röda blodkropparna där hem används till att transportera syre i kroppen. Tyvärr är obundet hem giftigt. Det har visat sig att havandeskapsförgiftning, ett tillstånd som kan drabba gravida,
Water is necessary for all life and one of the most important natural resources. The water resources problems were the reason why the project Development of the Altiplano area in Bolivia: a collaboration between Lund University (Sweden) and San Andres University in La Paz (Bolivia) was started. In the project PhD students are investigating the groundwater aquifer Challapampa that supplies the city
When live theatre is broadcast in real time at cinemas around the world, there is a gap in the current terminology. ’Mediatised live’ is a new expression, established in this thesis, to name the media form which has revolutionised the way of experiencing live theatre by broadcasting theatre live to venues around the world. By asking the question ‘Is the need for liveness dying?’ this thesis invest
