As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

This project concentrates on musicians who work in a professional music studio.The task of this project was to design a new headphone system called Foldback system.The advantage of this system is that all involved in a music project could influence their ownlistening during the project. With a couple of adjustments should each and everyone get theirown individual listening from their headphone station.This report shows different methods, theories and results that came along in development ofFoldback system. The project has resulted in a finished product that will be in use atStudiomega..

The author of this report has created a Web-based invoice system and CRM at therequest of the company Webhouse.se. The purpose of the System is to makeeveryday tasks in the company easier. The system also needed to prevent mistakesand errors by managing orders and invoices.The system has been created with the company?s requests in focus. During thedevelopment of the system information security and interaction design have beenimportant aspects that have been taken into consideration.The system has been created using techniques such as PHP and MYSQL.

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..

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

F?rorter, omr?den som pr?glas av konsekvenserna av ekonomisk oj?mlikhet och utanf?rskap. Socioekonomiskt utsatta omr?den d?r inv?narna lever i ?r en milj? med f?ruts?ttningar och m?jligheter som ?r f? och emellan en milj? d?r bristf?lliga resurser och f?ruts?ttningar ger kriminaliteten utrymme att trivas i. Alla tycks ha n?got att s?ga om f?rorten, f?rutom m?nniskorna som ?r bosatta d?r.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Bakgrund och problem: H?llbarhet och milj? har de senaste ?ren kommit att bli en alltmer aktuell och central del av f?retagens strategi och aff?rsid?. Det har blivit mer relevant i takt med att f?rst?elsen kring hur konsumtion och produktion p?verkar milj?n har ?kat. Som en f?ljd av det har cirkul?r ekonomi kommit att bli en process som f?retag till?mpar f?r att f?rb?ttra sitt klimatavtryck.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

Bakgrund: F?r?ldrars delaktighet i v?rden av sitt sv?rt sjuka barn ?r en h?rnsten inom familjecentrerad v?rd. Tidigare forskning visar att f?r?ldrar ?nskar vara delaktiga, men upplever att m?jligheten ofta begr?nsas av organisatoriska faktorer och barri?rer skapade av sjuksk?terskor inom intensivv?rden. Syfte: Att unders?ka sjuksk?terskors upplevelser av f?r?ldrars delaktighet i v?rden av deras sv?rt sjuka barn p? en intensivv?rdsavdelning.

This paper discuss the possibilities to improve the Swedish political nomination system. It brings up some of the values and norms that can be used to change the existing system. Values as openness, the demand of responsibility and also if there is values from the American spoils system that can be used in the Swedish system. A minor purpose is to discuss the part of the parliament within the nomination process. To investigate this I have some theoretical starting points and a self constructed analysis tool.

Climate change is a phenomenon that know no boundaries. While focus on environment and climate change has become highly prioritized, nationalism has spread across Europe. Nationalism is by many considered to refuse action to combat climate change although some argue that nationalism could combat global climate change. Previous research on how nationalism is implemented in environment and climate politics has mainly focused on single parties. The thesis therefore aims to give a broad approach and compare how nationalism is used in environment and climate politics by analyzing 4 European parties with either ethnic or civic nationalism and different roles in their party system. With a qualitative content analysis on party programs and election manifestos the findings imply that parties use nationalism in the climate and environment discourse in a variety of ways.

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

Studiens syfte ?r att unders?ka hur grundl?rare med inriktning fritidshem talar om m?jligheter och utmaningar med att implementera utomhuspedagogik i fritidshemsverksamheten. Det r?der idag brist p? forskning om utomhuspedagogik som riktar sig specifikt mot fritidshemmet. Trots att utomhuspedagogik ?r en del av grundl?rarutbildningen med inriktning mot fritidshem, s? verkar utomhuspedagogisk verksamhet ofta sakna syfte och m?l.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.
