Denna rapport har sitt ursprung i det kodefaktoriseringsarbete som utfärdats våren 2013 som examensarbete i dataingenjörsprogrammet vid Örebro Universitet. Arbetet utfärdades på Nethouse i Örebro, och hade stort fokus på koddesign och kodkvalitet.I rapporten diskuteras vilka faktorer som påverkar hur underhållbar och läsbar en kod är, men också hur man på ett rimligt sätt kan utvärdera och mäta kodkvalitet.Den teoretiska biten blandas med den praktiska, där läsaren introduceras för ett flertal metoder, och hur dessa sedan implementerades i det faktiska projektet som Nethouse tillhandahöll..

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error. .

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

With the increase in IT related crimes the IT forensics has more work ahead of them and it is constantly rising. The analysis software called EnCase is widely used by IT forensics all around the globe and with it comes an internal programming language called EnScript.This paper is designed to examine whether a manual for the programming language EnScript can make a difference in how efficiently the work is.A study between two groups has been made and an evaluation of the results between the two groups.The manual provided aims to introduce the reader to EnScript as a programming language and also to provide a solid foundation to build on in further work with EnScript.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system. Based on documentation obtained through interviews a demo system was created based on Bluetooth Low Energy (BLE) communication between an embedded system and an Android device.This report intends to describe the tools and methods used in the design of the demo system and the result of an analysis of the BLE communication.Bluetooth Low Energy is an exciting protocol with wide applicability within the industrial field. This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

Abstract (in English)The work that lead to a CE- marking and the creation of a total drawing foundation on an existing machine carried out on the company Polytec Composites Sweden AB in Ljungby. The company have design an machine that exist in six example that runs in the production. To be able to use the machine the company have to work out a CE-marking. The process that summed up all the document that needs for the machine to make a CE-marking. The documentation includes a total drawing over the machine and a risk analysis performed by a group employers on the company.

Music production software has a strong tradition of two-dimensional graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

Syftet med detta examensarbete är att med avseende på Snow Softwares databas försöka att effektivisera samt omstrukturera de procedurer som hanterar deras regelverk. Den är ej inriktad på att utvärdera eller förändra de algoritmer som redan finns i Microsoft SQL Server.Ett flertal olika prototyper framställdes och utvärderades. Dessa var ej specifika för just denna databas och kan därför vara intressanta även i andra sammanhang. Den prototyp som visade sig vara mest effektiv implementerades så att den enkelt skulle kunna tas i bruk i det nuvarande systemet. Prototypen gav en ungefärlig förbättring i söktid på 18,8 %.

With recent technical development computer aided design and manufacturing has taken amore important role in the product life cycle. New business segments such as Product/ServiceSystems and remanufacturing is emerging. This development demands better control of theproduct data throughout the entire product life cycle. Computer aided design is widelyrecognized and used within the manufacturing industries and in recent years the importance ofDigital manufacturing has increased. One part of Digital manufacturing is paperlessproduction which involves all orders and working instruction shown for example on a screenrather than on a piece of paper.

SammanfattningStudiens syfte var att undersöka förskolans dokumentation utifrån relationen till barnet, verksamheten och det systematiska kvalitetsarbetet, samt hur detta relateras till utvärderingsarbetet. Syftet preciserade med följande frågeställningar: I vilken grad används olika underlag i förskolans systematiska kvalitetsarbete för att dokumentera? I vilken grad uppfattar förskolans lärare att det systematiska kvalitetsarbetet i dokumentation, utvärdering och analys utförs? Finns det några samband av förskolans lärares syn mellan utvärderingens analys till det konkreta utvecklingsarbetet?  Enkätundersökningen genomfördes genom att 14 förskolor besöktes och totalt 100 enkäter delades personligen ut till förskolans lärare, varav 78 besvarades. Enkäten bestod av olika påståenden utifrån syfte och frågeställningar, som förskolans lärare skulle ta ställning till. De statistiska analyser som används var univariat deskriptiv analys, ANOVA, multivariat variationsanalys faktoranalys.Studien utgår från ett postmodernt synsätt, där det förstås att det inte finns någon absolut kunskap i pedagogiska sammanhang, och där vår värld och kunskap kan ses som en socialt konstruerad process, där alla aktivt deltar.Resultatet visade att det underlag som förskolans lärare använder för dokumentation är verktyget ?foto? och att pedagogisk dokumentation ses som ett arbetsredskap, som synliggör förskolans verksamhet, och kunskapsområden.

I detta arbete har vi undersökt vilka faktorer som är viktiga för ett lyckat införande av CASE verktyg i en organisation. I arbetet har vi utgått ifrån de faktorer som teorin förespråkat och jämfört dessa med den empiri som vi har undersökt. De faktorer som vi har funnit i litteraturen har vi delat in i grupperna organisatoriska faktorer, utvecklingsfaktorer och stödjande faktorer. Vi har funnit att hanteringen av dessa faktorer i många fall skiljer sig mellan teori och empiri. Utifrån undersökningen har vi dragit slutsatsen att utvecklingsfaktorer har varit den grupp av faktorer som har påverkat införande mest i de undersökta företagen..

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.
