The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Idag finns det 5200 mjölkföretag i Sverige varav 69 procent tillämpar ett uppbundet system. Regeringen föreslår att Jordbruksverket bestämmer ett slutdatum för mjölkproduktion i uppbundet system. Målet är att förbättra djurvälfärden för nötkreatur. För den enskilde lantbrukaren innebär ett förbud mot uppbundet system ett vägval mellan att avveckla eller investera i mjölkproduktionen. Vid ett stoppdatum för uppbundet system kan det uppstå kapitalförluster för de mjölkproducenter som tvingas avveckla i form av en minskad arbets- och kapitalinkomst.

 AbstractSystem methodology is in the very heart of system development, it is a crucial part of how you define your work, how you choose to approach the actual problem at hand and how to solve it. Researchers in the system development field has shown that not all methods in theory are in compliance with how it is practiced by the companies who use them. In our thesis we have studied a larger international IT- company and one of their local offices in Sweden, who some years back changed their system development method from a more traditional to an agile one. Our aim of this study has been to establish whether both of these methods has differed between theory and in actual use, and if so, why this has occurred and what the underlying rationality might have been to promote this change. Our questions that we sought to answer were; 1.

One of our reasons is that we think the subject usability is interesting, is that we think it is an important. Usability is maybe the most important element when you develop or choose a system because it can save money for the companies and give the users a more delightful and better work environment. The aim of the investigation is to find out if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. The objective of our investigation is to show if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. In our case we will try to see if Karlshamns AB:s recently implemented web portal is more useful than their previous application (Movex with interacting programs) One thought with the report is to give the system developers a perspective of how the usability can be in-house made applications versus standard applications.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

For a long time economic tax equalization system in Sweden has been creating dispute between Swedish communities. Despite the main purpose of the system - to reduce disparities and create equal economic opportunities for all communities ? some regions were not satisfied.The main purpose of this study is to determine what extant has equalization tax on investment spending of Danderyd municipality during 2000-2010 year period. The study is based on annual reports and personal interviews. The theoretical frame of the investigation is founded on Fjertorp's classification of investments and public choice theory.The investigation shows that there were no significant changes neither in investment spending or equalization tax during 2000-2010 period, even after the last changes of economic tax equalizations system in 2005.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

Organisationer och personer runt om i världen blir alltmer beroende av olika former av IT-stöd. För att effektivisera arbetet skaffa sig organisationen nya system eller försöker förbättra det redan befintligt systemet. En användare kan reagera på olika sätt vid införandet av ett nytt system beroende på olika faktorer hos systemet eller personen. Jag studerade ett komplett Care-system som används inom äldreomsorgen. Ett Care-system kan bestå av en webbapplikation inklusive digitala och mobila verktyg.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

The purpose of this study was to try to understand the Swedish population regarding the perceptions of the Swedish welfare system, based on the reactions that occurred after Sweden's Prime Minister Fredrik Reinfeldt's statement about raising the retirement age. Our results demonstrate that the reactions on changes in the pension system in fact rooted in a safety factor and not the change in the pension system itself, through which the Swedish welfare system acts as a safety net for the population. Further the results shows that these safety factors create a form of egoism. With an interaction between empiricism and theory, where the starting point of the material was of an inductive approach, the material abstracted into different levels from which the result emerged. The focus of this study lies in the understanding of how human beings act according to one's need for security in major changes, which may be of importance to a comprehensive understanding of changes in social structures..
