Sammanfogning av videosekvenser från flygburna kameror
The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..
Processutveckling av borstgradning

The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.
Den krokiga vägen till läsning : En kvalitativ studie om lärares arbete med elevernas tidiga läsinlärning
The purpose of this study is to contribute to our knowledge about what methods? teachers say they use in the work with pupils? early reading acquisition, and how they evaluate the pupils´ reading development. I also like to find out what educational interventions teachers believe that pupils with reading difficulties need, and how they say they work to meet the needs of these pupils. The project is based on the following questions: What methods do teachers say they use in the work with pupils early reading acquisition? What extra resources do teachers consider that pupils with reading difficulties need? How do teachers evaluate children's reading development? In order to answer my questions, I've done qualitative interviews with three teachers, at two schools, in two medium-sized municipalities.
Hållbarhetsredovisning i svenska företag: - en kvalitativ studie om drivkrafter och redovisningsmetod
Sustainability reporting in Sweden is a voluntary disclosure action for non-governmental companies. Since 2009 all state-owned companies must however publish a sustainability report according to GRI guidelines and with independent assurance statement. Three different sustainability reporting methods are primarily used: (1) Separate Sustainability Report, (2) Sustainability Report included in the Directors? Report, and (3) Sustainability Report forming part of the Printed Annual Report. The aim of this paper is to explore why some companies choose to publish a sustainability report and identify the motivational factors behind this decision, as well as attain an understanding for companies? choice of reporting method.
Hur fungerar egentligen ko?pbeslutsprocessen inom e-handel? : En kvalitativ studie om konsumenternas beteende vid konsumtion pa? Internet.
Title: How does the buying decision process really function within e-commerce? - A qualitative study of consumer behavior when they consume on Internet.Institution: School of Economics, Linnaeus University, Va?xjo?.Course code: 2FE16E.Authors: Sara Hja?rne, Mathilda Perem, Ewelina Wallin.Tutor: Dan Halvarsson.Examiner: A?sa Devine.Key words: Buying decision process, purchase decision process need recognition, information search, evaluation, purchase decision, postpurchase behavior, consumer decision making, E-commerce, E- commerce channels, online shopping, online purchase, e-retail, internet shopping, electronic shopping, consumer behavior, online appereal shopping, social media, decision making, online retailing, website design, customer satisfaction, webshopping, perceived risk, convinience, price, online consumption behavior.Background: Buying decision process is a model that marketers use to get a better understanding of their customers and their behavior when purchasing a product. This process consists of five different steps; need recognition, information search, evaluation of alternatives, purchase decision and evaluation. Buying decision process has for a long time been an accepted model but scientists argue that the introduction of Internet as a channel for consumption has changed this process. The Internet has also led to a change of power in which customers today have greater influence, which greatly affects the buying decision process in e-commercePurpose: The purpose is to explore how consumers perceive their behavior when they consume through e-commerce.Research questions:How do consumers perceive the buying decision process they experience when they consume through e-commerce?How do consumers perceive different factors that are important to them when they consume through e-commerce?Methodology: Qualitative study, cross-sectional design, semi-structured interviews.Conclusion: This thesis shows that the traditional model of the buying decision process is not consistent with consumers' perception of how they are undergoing the process when applied to an e-commerce context.

Massundanträngning i samband med pålning i lera
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Utvärdering av öppna dikens status och funktion : en förstudie i Västmanlands län
Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative.
To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating
problems.
This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality.
The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles.
The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations
and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

Hur förselektion av hästar till bedömning och tävling kan hanteras i avelsvärderingen
The Swedish Warmblood riding horse is a popular horse for sport in Sweden, and the breeding goal is to produce competitive horses in both show jumping and dressage. The breed has its origin in native Swedish cavalry horses but has been highly influenced by foreign stallions throughout the years. Breeding values are estimated based on the results from young horse field test, which are held for 3- or 4-year old horses, and competition data. The young horse field tests are highly correlated with later performances in competition. The total proportion of horses with own observations to include in the genetic evaluation are slightly under 50 %, and in most cases their pedigrees are known.

Grundvattenpåverkan kring järnvägstunnlar i berg
Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.

Konsten att dansa tango En studie om relationen mellan förvaltningschefer och politiker i Bromölla kommun
This essay studies the relationship between politicians and municipal chief officers from the point of view of the bureaucracy and its role in democracy and the substance of the chief position. I conducted interviews and observations with politicians and senior officials from the local public administration in Bromölla. The roles of the chief officer and politicians have certain common characteristics which makes it difficult to separate them. Senior officials working full time in contrast to part time politicians give them an advantage in the political process. Budget cut backs both enhance the role of politicians and chief officers in the administrative organisation.
