Kickstarting a Kickstarter : Kommunikativa komponenter i lyckade & misslyckade crowdfundingkampanjer
Crowdfunding is described as a facilitator for creative entrepreneurs in their gathering of funds for projects. This bachelor?s thesis aims at finding differences in communication components found between successful and unsuccessful crowdfunding campaigns on one of the most popular platforms, Kickstarter. Through a quantitative content analysis and a rhetorical analysis of literary topoi this study suggests that there are apparent differences in usage of titles, text, visual expressions, rewards and in themes of preparation, humility as well as quality. The findings we present conclude that a campaign with a title consisting of eight words and one punctuation are more likely to succeed than other.
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.
En övervikt av kvinnor : En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv
We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.
Användbara CASE-verktyg : Utformning av CASE-verktyg med fokus på användbarhet
CASE är en förkortning för Computer Aided Software Engineering. Syftet med CASE-verktyg är att öka produktiviteten för dem som utvecklar mjukvarusystem genom att datorisera processer i deras arbete.Det finns dock problem med CASE-verktyg. Tidigare forskning pekar på att dessa ofta är komplexa i sitt utförande, att de lätt ifrågasätts om de visar sig ha buggar och att inlärnings-tröskeln är ofta hög till följd av den höga komplexiteten. Man frågar sig också hur komponenter ska vara utformade i verktygen för att fler ska använda dem. Vidare saknas nyare undersökningar med fokusering på användbarhet för CASE-verktyg och framförallt där man utgår från användaren.Vad gäller CASE-verktyg har det skett en del begreppsbyten inom området.
Automatiserad Konstruktion av Varmkanalsystem
The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.
Visuell planering enligt Lean : Optimering av samordning i syfte att höjakvaliteten i grundläggningsprojekt
Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.
Känslan i bilden : Sociala taggars användbarhet vid bildsökning i Flickr
Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.
Webbportal för flygbolag
Examensarbetet handlar om utvecklandet av en webbportal för ett litet flygbolag. De behövde en plattform för att kunna hantera och digitalisera olika dokument. Den viktigaste funktionen som implementerades var flygloggen som fylls i efter varje flygning. När den är digital kan flertalet uträkningar ske automatiskt och exportering av statistik kan ske mycket enkelt. Resultatet blev en webbapplikation i ASP.NET och MVC med Visual Studio som också lades upp på molnet med Microsoft Azure..
Framväxten av den icke-euklidiska geometrin
The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..
Förekomst av PFAS i micropopcorn : Migration och hälsorisker
PFAS är en grupp poly- och perfluorerade ämnen som framställs industriellt och förekommer i ett flertal produkter såsom impregnerade papper och textilier, brandskum och rengöringsmedel, detta på grund av dess smuts, vatten- och fettavstötande egenskaper. Ämnena klassas som PBT ämnen, persistenta, bioackumulerande och toxiska, vilket gör dem till ett hälsoproblem för människor och djur. Denna studie undersökte förekomsten av PFCA, PFSA och PAPS i micropopcorn, samt om migration från förpackning till majskorn innan tillagning förekom och om PFAS i popcornen kunde utgöra en hälsorisk för människor. Proverna bereddes genom att tillaga ett prov i mikrovågsugn, ett i kastrull innehållande majskärnor samt fettet från micropopcornpåsen och ett där majskärnorna tvättades rena från fett från påsen och därefter tillagades med rapsolja i kastrull. Proven extraherades bland annat med en SPE Wax + HLB, separerades i en Acuity UPLC och identifierades med hjälp av en Xevo TQ-S-quadrupole masspektrometer med atmosfäriskt elektrospraygränssnitt i negativt läge samt analyserades i mjukvaran Masslynx.
CE-ma?rkning av produkter under byggproduktfo?rordningen
The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.
Så gör vi gott för Norrland - : En kvalitativ studie av Norrmejeriers visuella kommunikation
In a time where information overload is a fact, well formulated messages is required and communication is a big contributing element for building strong brands. In the north of Sweden, Norrmejerier is one of the big actors with dominance on the dairy factor market. Through making milk products that lands in the consumers refridgerators, they are not only working for economical interest but also for improving the nature of the north of Sweden. Through visual communication, Norrmejerier shows the consumers a beneficial view of the north of Sweden which corresponds to the populations own impression of their part of the country. This contributes to a feeling of belonging that makes strong and loyal consuments. The feeling of belonging is also reflected in Norrmejeriers commercial movies, that uses the consumers conscience to make costumers. By two group interviews and a semiotic analysis of Norrmejeriers commercial movies, this study aims to examine how Norrmejerier uses qualities of the north of Sweden when building their brand.
Att kommunicera idéer och visualisera information i 3D :
In order to respond to a more complex community planning with increased
cooperation and public participation, a common language and a common
model to be used as a base for the communication process is needed. The
thesis behind this dissertation for a master's degree is that a virtual 3D
planning portal would respond to this need. Why and how are explained and
described through studies of communication- and perception theory as well
as technology and recent research.
The introduction concludes that a broad participation and a transparence
towards underlying information are important foundations for the coming
work with the model. The first four chapters of the theory part show the
benefits of using natural signs in our mixed cultural society, instead of the
more arbitrary symbols. Using visual landscapes for storing information is
motivated by the flexibility of our visual memory and its ability to
understand complex connections.

Uppbyggnaden av ett foderstatsprogram för dikor :
The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic.
I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout.
Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.
