Background For a long time, Axis has mainly focused on network cameras. But lately Axis is turning its focus towards a different kind of approach, looking more at the customers and their needs, which has given end-to-end solutions and customer segments increased attention in different departments within Axis. A sustainable portion of Axis’ offering is its accessories, but this branch of products h
Bakgrund: Den industriella eran har kommit till sitt slut och med en ny epok kommer nya förändringar. Nya generationer växer upp i en allt mer digitaliserad värld och deras digitala kunskap, tillförlitlighet och sätt att leva påverkar hur vi kommer att arbeta och leva i framtiden. Digitalisering håller på att skriva om spelreglerna för hela branscher och organisationer. Företag med ledare som välj
The aim of this thesis was to investigate methods for artifact removal in PPG signals and to implement and evaluate a few existing algorithms claiming that the amplitude information is recovered when removing motion artifacts from photoplethysmographic signals (PPG) captured from pulse oximeters. We developed a new proposed method that uses a two-stage based approach with singular value decomposit
This paper seeks to develop an understanding of how configurations of masculinity were shaped and represented by the Swedish Ballet in the 1920s through the use of a symbolic language of signs. With in-depth analysis of storylines, roles and scenography I aim to show how certain symbols, signs and metaphors where tied together to display masculinity. Further, by applying theory on space/place, thi
Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m
In this thesis two methods are investigated to solve a multi-objective optimization problem for voyage planning. The first method, grid search, is a brute force search in a three-dimensional graph while the other uses the Lipschitzian algorithm DIRECT to do a continuous search along a nominal route. The grid search method gives a computation time of 7.6 minutes for a route from Gothenburg to New
Models of physical systems are often expressed as a system of mathematical expressions derived from first principles. However some of the relationships present in a model are more conveniently expressed as a table, i.e. for certain values of independent variables the values of dependent variables are known. This imposes a limitation on the optimization software to be used, since optimization softw
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
