Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
Integration av konstruktionsdatabas och styrsystem
The Mission at ÅF Industry in Norrkoping was about optimizing bulk data handling while importing process tag types from their construction database into the Process Controlled System of type Siemens PCS7.I found three different methods to solve the task. Two of them were using different software from Siemens under the premise that the report from the database was corrected as needed. The third variant was manually creating the circuits. All methods worked out fine but there were times when one was better than another.To solve this task I had access to all software presented in chapter 2 ?Programvara? (=Software).
Intellectual Property Rights in Software : A Critical Investigation from an Ethical Perspective
The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.
Software keystroke logging : Automatisering av skydd mot software keystroke logging
This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

The study alsoshows the importance of being able to share information, on how the program will beconstituted, to someone outside the organization..
Programmering av mikrokontroller för styrning av komponenter i ett biokemiskt analysinstrument
The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.
Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012
This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks
Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.
Mjukvaruverktyg för loggning och analys avindustriella processer
This report discusses developing a software log tool for analysis of industrial processes. The target was to develop software that can help electro Engineers for monitor and fault finding in industrial processes. The tool is called PLS (Process log server), and is developed in Visual Studio.NET Framework 2005. PLS works as a client with Beijer Electronics OPC Server. The program is able to read data from PLC (Programmable Logic Controller), trough the OPC Server.

Tillämpning av lättrörliga systemutvecklingsmetoder - en studie av systemutvecklingsprocessen i en ad hoc-krati
Due to fast growing and rapid changes in markets today, most of the organizationsthat are trying keep up with these changes have a high demand for software that areof high quality and comes with a low price. To meet these goals software companieshave to implement new methods to develop software that are suited for rapidchanges. The concept of agile methods can fulfill this need. Our purpose with thisthesis was to investigate how well agile methods could be applied in organizationsthat could be identified as adhocracies. A case study was conducted in anorganization which we could identify as an adhocracy.
Preflight utvärdering
PDF-files are to become a native file format in all prepress supplier workflows during 2006. This will give an opportunity to automate and develop a more stream lined prepress workflow. It is desirable to secure digital files by preflight the files early in the process. The objective with this project is therefore to find software that can automate parts of the preflight process and also to build up a well-functioning preflight workflow for preflighting both PDF-files and native files.Meetings have been held with preflight suppliers to find a solution for how to automate parts of the preflight in the prepress workflow. Seven preflight software companies demonstrated the possibilities with their products and four of these were chosen for continuing working with.
Mjukvaruföretagens strategiska agerande
Background: In recent research literature, some researchers mean that companies in fast changing markets have to act proactively while others find that companies have to adapt to conditions and to react. This makes it interesting to study how software companies act strategically and also to study to what extent a flexible organisation is required by companies who proact and by those who react. Purpose: The purpose of this thesis is the study how different types of software companies act strategically and what this requires of the company in terms of flexibility. Delimitation: The study treats only Swedish software companies with more than ten employees. Proceed of the Study: Representatives from four case companies as well as a consultant have been interviewed.
Migration av distribuerad relationsdatabas för lagring i webbläsare
An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers? browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess.
