Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

The communication with government and municipality through Internet has in-creased during the last couple of years. Therefore we have chosen to focus our bachelor thesis in this particularly area and the needs for usable web services for the citizens. In this bachelor thesis we are studying a increasing group users, namely elderly citizens. During the study we have analysed E-governments ser-vices usability through usability tests. The combination of conversations and meetings with individuals, observations of interactions and literature studies give us the opportunity to explore the users needs.

MindMe is an aid for people with cognitive memory impairments.

Globaliseringen innebär ökad konkurrens för företag vilket gör det viktigare för företag att snabbt kunna utföra sina kostnadsuppskattningar. I detta arbete undersöks förutsättningarna för att använda moderna teorier inom cost engineering för att kunna förkorta ledtiderna vid förkalkylsarbetet för företag inom custom made-tillverkning. Inom cost engineering har teorier för kostnadsuppskattning används för att beräkna tillverkningstider för tre olika produkter hos ett fallföretag. För att få en bra beskrivning av problematiken med kostnadsuppskattning inom custom made-tillverkning har design science-metodologi använts under arbetets gång.  Resultatet av arbetet visar att förutsättningarna för att använda moderna teorier inom cost engineering för kostnadsuppskattning hos custom made-tillverkande företag är att historisk data avseende för- och efterkalkylsarbete finns tillgänglig.

Denna uppsats har som syfte att klargöra hur långt det är tillåtet att med reverse engineering experimentera med en patentskyddad uppfinning innan patentintrång föreligger. Främst förs en diskussion om hur långt det är tillåtet att experimenteramed en patentskyddad uppfinning, utifrån patentlagens experimentundantag, utan att kränka ensamrätten som patentet ger. För att svara på denna fråga börjar diskussionen ur ett svenskt perspektiv i den svenska patentlagen, med ett instick ilagen om skydd för företagshemligheter. Diskussionen förs sedan ut i Europa för att se hur bedömningen av reverse engineering och experimentundantaget gjorts där och till sist vänds blicken mot USA. Bedömningen som görs är att reverse engineering ges ganska fria händer så länge målet för processen är att finna ny kunskap utöver den kunskap som finns inbäddat i patentet.

This bachelor thesis portray a project where the main task were to develop a computer based system prototype for handling of absence report at the upper secondary school af Chapman in Karlskrona. The project has been conducted in cooperation with students from the university programs software engineering and information economy at Blekinge Institute of Technology. Our task as MDA-students have been to survey the process of absence report of today through field studies and give a proposal of a graphical user interface which later were developed by the software engineers. The thesis also handles the cooperation with other students from other university programs..

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

This bachelor thesis looks at developers knowledge about web security both regarding their own view on their knowledge and their actual knowledge about vulnerabilities and how you mitigate against them. Web developers knowledge regarding web security are becoming more and more important as more applications and services moves to the web and more and more items become connected to the internet. We are doing this by conducting a survey among developers that are currently studying in the field or are working in the field to get a grip on how the knowledge is regarding the most common security concepts. What we saw was that the result varies between the different concepts and many lack much of the knowledge in web security that is getting increasingly more important to have..

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

This paper discusses sound education within school subjects such as music, science, engineering, computer science, and Swedish to classes at the intermediate stage..

Abstrakt Social Engineering är konsten att manipulera människor, för att på så sätt vinna deras förtroende. Med hjälp av detta förtroende kan attackeraren sedan kringgå säkerhetssystem och få tillgång till organisationers information. Vi har i denna uppsats genomfört elva intervjuer på tre stora organisationer med både IT-chefer och övrig personal. Med dessa intervjuer har vi sedan försökt få en bild av hur medvetenheten ser ut samt vilka åtgärder organisationerna tar för att förhindra Social Engineering. Med denna uppsats vill vi belysa den ovisshet som råder kring Social Engineering, men även farorna och hur effektiv en attack av denna typ kan vara.

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant. By also documenting how much time we spent involving users we will show to which degree user involvement is effective. We found out that a couple of fast techniques could get very much result in the form of usability enhancing suggestions to the developers.
