This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

På uppdrag av Volvo Lastvagnar har detta examensarbete genomförts under våren 2013 för att undersöka potentialer av energibesparande åtgärder i måleriet. Syftet med uppdraget var att utveckla en energimodell över måleriet i byggnad UD, där användaren kan testa olika driftparametrar för att se måleriets potentiella besparingar ur en ekonomisk och energimässig synvinkel. Energimodellen byggdes i Microsoft Excel och arbetet innefattar tydliga redogörelser över de energikrävande processerna, samt över de data som ligger till grund för modellens beräkningar. Data över 2012 års driftsituation har använts som grunddata i modellen och analyser av dessa tyder på att stora energibesparande åtgärder är möjliga.De lastbilshytter som lackeras i Line 3 är de i särklass dyraste, då Line 3 i dagsläget används väldigt ineffektivt. Av den maximala kapaciteten på 12,9 hytter per timme, använder Line 3 endast mellan 8 % och 15 %. Modelleringar visar att en reduktion av drifttiden på Line 3 från ca 95 timmar per vecka till 40 timmar per vecka skulle medföra en minskad driftkostnad på en dryg miljon kronor per år.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

IKEA HaparandaTornio employ some two-hundred people in its furniture retail store.Keeping track of staff statistics and employee information has previously been achievedthrough the use of a basic Microsoft Office Excel spreadsheet. The store?s human resourcesdepartment requested an upgrade to this system with the hope of speeding up andsimplifying the administrative process, as well as to make it easier to monitor HR-relatedtarget statistics. The following report documents the development process of that upgrade ascarried out by the author. The project draws on research in usability design and cognitivepsychology to develop a user-friendly interface.

My intention with this study is to evaluate, as a singer and a voice teacher, a number of routines for daily vocal practice through practical application. Seven different routines are presented, five of them originating from interviews with Swedish vocal teachers and singers and two chosen from literature. These routines are then tried out and evaluated. Using the results of these evaluations as a basis, I make an attempt at formulating my own personal practice routine, optimal for my own needs. I will also try to address motivational issues related to practice with hints acquired through the interviews.

This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

SharePoint är ett stort content- och managament-system som många företag använder sig av. I detta kan mallar specificeras för olika dokumenttyper (kallade content types), som underlättar skapandet av nya dokument för slutanvändaren. Systemet för mallarna blir dock snabbt omständligt och ohanterligt när antalet mallar företaget använder sig av växer.I detta examensarbete undersöks en lösning till problemet med mallarna, som finns tillgänglig på Microsofts Codeplex-site, där projekt under open-source licens kan laddas upp för allmänheten. Under arbetet undersöktes denna lösning djupare och vidareutvecklades för att i slutet av arbetet kunna levereras i form av en prototyp som HOW Solutions kunde använda sig av i framtida projekt.Slutresultatet blev en prototyp som bygger vidare på den tidigare lösningen och som tillåter användaren att specificera en mall-hubb, i form av en site-samling med bibliotek som kan förse andra bibliotek med mallar. Under projektet blev också en annan vidareutveckling av programmet funnen, som visar stor potential och som bör tittas närmare på..

This final-year project has been performed at Strix production Efterlyst. The task has been to make a page under their homepage, with a game application that?s supposed to be interesting and also have a strong connection to the TV- program. In the first part of the report, the reader will learn about the preparing work that was done before the work with the final game began. It is in these two test versions all the technical problems were tested, to finally be used or thrown away.

When an error occurs in an IT system that is vital for the production of a major industry, the consequences can be great. To quickly identify and correct errors is important as a stop in a system can lead to a break in production, which is costly for the industry. Our task in this thesis has been to develop a system for ÅF that facilitates the debugging process of the system Paperline. The system's target audience is ÅF-call personnel that provides support for Paperline 24 hours a day if something goes wrong. The system consists of a Windows service, a database and a web application and is developed mainly with the techniques C#.NET, MVC 5, Google Charts, Javascript, HTML, CSS, and Entity Framework.

Denna rapport undersöker olika tekniker för att spara data lokalt i webbläsare, föratt möjliggöra att webbapplikationer kan användas i webbläsare närinternetanslutning saknas, och för att minska mängden data som behöver överförasmellan webbserver och webbläsare.Undersökningen genomförs genom att en befintlig webbapplikation först undersöksför att avgöra vilka datamängder som behöver sparas i webbläsare.Sedan jämförs olika teknikers egenskaper och tidsåtgång för att spara data av olikastorlekar.Resultaten från undersökningarna visar att stödet i webbläsare för FileSystem APIoch IndexedDB inte är tillräckligt för att teknikerna ska användas i publikawebbapplikationer, varför HTML5 Application Cache i kombination med WebStorage är det bästa alternativet att använda för att möjliggöra attwebbapplikationer kan användas utan internetanslutning..

For better understanding of how users interact with the video on demand service Netflix a study was conducted in 10 Swedish households. This study is based on the well-established heuristic evaluation method of Jacob Nielsen, which we modified slightly by letting the users to act as ?evaluation experts? and informing them about the heuristic rules of thumb during the evaluation process. The purpose of this study was to identify usability problems when people interact with Netflix? interface.

Det finns många olika typer av affärssystem på marknaden och företagen har investerat i egna unika IT-lösningar, vilket har medfört att man har låst in sig i den egna tekniska plattformen genom bland annat punkt till punkt- implementationer. För att råda bot mot detta är det då önskvärt att olika system och applikationer ska kunna kommunicera med varandra genom att utbyta data på ett standardiserat sätt. För att uppnå dessa integrationsmål har en tjänsteorienterad arkitektur, Service Oriented Architecture (SOA) växt fram. Syftet med denna uppgift är att undersöka möjliga metoder för att utveckla en tjänstebaserad arkitektur för integration mot Avantra AB:s upphandlingssystem, Avantra Upphandling. Detta utifrån krav och direktiv som ställdes av Avantra samt de möjligheter och begränsningar som styrs av deras utvecklingsmiljö, -verktyg och -rutiner.

This project aims to explore fear of violence in public places. Fear of violence reminds us that there is a problem in our urban environment that leads to spatial consequences in using public space. Many groups in our society experience fear in their everyday life but this project has focus on women?s fear.

As the speed and complexity of computers have increased so have software and the expectations of users. Software development follows a straightforward evolution where complicated tasks are made easier by better tools; this repeats itself as those tasks in turn are automated.Software mechanics that were seen as revolutionary a decade ago are seen as obvious requirements that no multimedia application can be without.dotNet is the next step in line and makes it easier and faster to build software.This report focuses on the development of a multimedia platform developed in dotNet. It does this by developing the tools and framework from which a complete game can be built.A game is selected because it combines the most aspects of multimedia development, such as interaction, graphics, sound & music. The report goes further by describing why the game looks like it does as well as the mechanics of the game and the benefits of the dotNet platform..
