This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground Target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a vehicle in the group can be updated.

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

Denna rapport har jämfört olika path tracking-algoritmer för att se vilken som presterar bäst för spelagenter som färdas i konstant hastighet. Tre vanliga path tracking algoritmer som ofta används inom robotik har valts ut för undersökningen, Follow The Carrot, Pure Pursuit och Vector Pursuit. Algoritmerna har implementerats i C# och simuleringarna har genomförts i Unity 4.0. Path tracking-algoritmerna har testats på ett antal olika vägar för att se hur de lyckas följa vägen. Av simuleringarna så visar det sig att Pure Pursuit och Vector Pursuit presterade likvärdigt för spelagenter i konstant hastighet samt att de presterade bättre än Follow The Carrot..

Informationsskärmar återfinns idag på en mängd olika platser: i butiker, bibliotek, buss- och tågterminaler och liknande. Informationsskärmar är på frammarsch och spås bli en ännu vanligare syn framöver. Oftast är dessa skärmar helt statiska, det vill säga det går inte att interagera med dem och i de fall de tillåter interaktion handlar det främst om pekskärmar. Pekskärmstekniken har dock vissa tillkortakommanden och det finns ett behov av att undersöka nya sätt att interagera med datorer och informationsskärmar. En teknik som funnits länge i olika former men fram tills nyligen varit relativt otillgänglig för vanliga konsumenter är eye tracking (ögonspårning), en teknik för att spåra ögonrörelser hos människor.Syftet med denna uppsats är att undersöka hur eye tracking kan kombineras med en informationsskärm.

The subject of this essay is the target audience consisting of males in the ages of 25-40 living inStockholm with academic background. The main subject is to describe the target audience in awider perspective and to look at their social media habits and see if there are any differencesbetween the younger and older half of the target audience and to compare the results with theoryabout generation x and y.

There are no guidelines regarding how companies should design status updates on Facebook which attain good readability and engage the readers. Half the Swedish population are Facebook-users, but companies have yet to publish comprehensible messages on Facebook which effectively include the recipients. Inclusion is not just a matter of accessibility, but also of readability.Therefore, I studied how status updates should be designed on Facebook in order to increase the readability and to engage the readers. My target group is 22-32 year olds, since the company I worked with wanted to target this group. I conducted my research through literature studies, interviews with the client, analysis of past status updates, questioned an expert in social media, and organized a group interview with the target group.My research shows that status updates should contain information that is topical, informative and relevant to the target group.

Kostnaderna i ett företag har blivit allt viktigare på grund av att marknaden ständigt förändras. Target Costing är en av de kostnadsreduceringstekniker som därför tillkomit. Den hjälper företag att sänka sina kostnader i utvecklandet av nya och även befintliga produkter. Fokuseringen ligger främst på produktens idé-, planerings- och designfas. Target Costing används idag främst av tillverkande företag medan tjänsteföretag inte uppmärksammat denna teknik på samma sätt.

Titel: Användningen av Target Costing - En kvantitativ studie om vad som påverkar användningen av Target Costing.Bakgrund och problem: Ekonomistyrningslitteratur publicerar frekvent studier om adoption av styrverktyg och vad som påverkar adoptionen. Dock är betydligt mindre känt om användningen av styrverktyg och forskare menar att det därför vore intressant att studera vad som påverkar användningen av styrverktyget Target Costing.Syfte: Studiens syfte är att förklara vad som påverkar användningen av Target Costing. Detta ämnar vi göra genom att undersöka sju variablers påverkan på användningen av Target Costing.Metod: Studien har ett kvantitativt angreppssätt med en deduktiv ansats. Datainsamlingen har skett med hjälp av en webbaserad enkätundersökning, vilken besvarades av 19 företag. Det empiriska materialet har sedan analyserats utifrån studiens hypotesformulering och teoretiska referensram om vad som påverkar användningen av Target Costing.Resultat och slutsatser: Kundernas sofistikeringsgrad och leverantörsbaseringsgrad påverkar svagt användningen av Target Costing.

The purpose of this study is to investigate the effect of using more promotion material to enhance the in-store communication of sales promotion. In the retail industry today the research regarding the benefits from using various in-store promotion materials is limited, thus this study was carried out to bring clarity to this subject. The study is carried out in two pharmacies and the design of the study was to add more promotion materials to one store, while keeping the other store in its normal condition and then let the stores change conditions after one week e.g. latin-square design. The data collection of this study consists of four different methods: sales data, a questionnaire with 182 customers, an observation study of 300 consumers and an eye-tracking experiment with 41 participants.

This study has researched how user click heatmaps and eye tracking can be utilized in usability testing. We have used the tools SessionCam and Tobii. We designed a website for a small clothing store and conducted usability tests, in order to evaluate the users clicks and eye movements in relation to design choices on the website. The aim of this study was to research how these tools can be integrated in usability testing and how results from the tests can be used to improve usability. We were able to use the recordings of clicks and eye movements and make design changes based on the findings.

AbstractThe purpose and vision for the municipality of Torsby are to connect with a younger population in the municipality by the year of 2012.This study is a qualitative survey of the target group ?the young ones? within the municipality of Torsby, which is the population between 17?35 years old.Because of the size and the different intrests between the individuals in this group it has been divided into three smaller groups.? High school students, 17-19 years old.? Returning seasonal workers, 20-26 years old.? People who has moved to Torsby and are now living in the municipality, 27-35 years old.The results of the study show that all the respondents believes that with the right communication channels a positive and strong communication between the municipality and the target groups can be reached. The message and the significance of the message are as important as the communication channels and all the target groups together would like to see a wider range of leisure pursuits that will suit the respective target group.The analysis and the results also show that the communication with the target groups should come about in different ways to be successful, both when it comes to fundemental reasons and choices of communication channels.The two youngest target groups has an adjacent and a similar need of well-founded and entertaining communication and information to rach a long-term result.The older group needs communication that will give them opportunity to reflect and concider the message, which means that the municipality of Torsby needs to adjust both the message and the communication channel for a quicker respons. This target group is also in need of further studies so the municipality of Torsby succesfully can plan a more detailed communication, this because the target group is a less homogeneous group than the two other target groups..

För att överleva på dagens konkurrensutsatta marknad måste företag tillägna betydande resurser till produktutveckling. Det gäller för företagen att tillverka produkter som marknaden efterfrågar till rätt pris och rätt kvalitet. Beslut som fattas under produktutvecklingen påverkar de framtida tillverkningskostnaderna för produkten och blir på så vis väldigt betydelsefulla. Target Costing är en metod för att bearbeta kostnader vid utveckling av produkter i enlighet med marknadens preferenser. Syftet med uppsatsen är att undersöka huruvida Target Costing kan leda till minskad osäkerhet vad gäller beslutsfattande vid produktutvecklingar.

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.

We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.
