Ett träd för ett annat
This project is a collaboration with Ett Klick för Skogen, a foundation that buys and preserves endangered forests in Sweden. There are several ways of helping the foundation, e.g. buy a tree and for this the buyer obtains a symbolic diploma. Many organisations uses this method to collect money and for me the lack of a thorough expressions are consistent. The objective with this project has been to renew these diplomas for Ett Klick för Skogen and in the long run increase the collections and preservation of endangered forests in Sweden.The idea has been to vivify hardwood trees in a new and rather poetic than pedagogic manner.
Vellinge Centrum : Centrumförnyelse
Vellinge är både centralorten i Vellinge kommun och en bostadsförort till Malmö. Orten består till stor del av villabebyggelse. Vellinges expansion kan härledas till två viktiga händelser där den första var järnvägen drogs in till Vellinge. Järnvägen skapade nya förutsättningar för industrier, handel och framförallt nya kommunikationer. Den andra händelsen var bilens starka intåg under 50-talet.
Layoutgenerator för serie/parallell-omvandlare
I digitala kretsar kan både bit-parallella och bit-seriella interface förekomma.T ex kan en integrerad digital krets (IC-krets) internt använda sig av bit-parallella aritmetiska kretsar medan dess kommunikation med andra integrerade kretsar sker bit-seriellt. Genom att använda seriell kommunikation mellan IC-kretsar kan antalet ben på kapslarna effektivt begränsas.Detta examensarbete gick ut på att göra en layoutgenerator för generering av en parametriserbar serie/parallellomvandlare och en parallell/serieomvandlare. När en krets använder sig av både bit-seriell och bit-parallell representation av data behövs dessa för att omvandla mellan formaten..
Överföring av digital video via FireWire
Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.
Barns upplevelser av rörelse : -en intervjustudie med sex- och sjuåringar
In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.
Utveckling av OBD-II-gränssnitt för fjärrdiagnostik av fordon
This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

Vellinge Centrum - Centrumförnyelse
Vellinge är både centralorten i Vellinge kommun och en
bostadsförort till Malmö. Orten består till stor del av villabebyggelse.
Vellinges expansion kan härledas till två viktiga
händelser där den första var järnvägen drogs in till Vellinge.
Järnvägen skapade nya förutsättningar för industrier, handel
och framförallt nya kommunikationer. Den andra händelsen
var bilens starka intåg under 50-talet. Bilen skapade
möjligheten att röra sig över längre sträckor vilket också
resulterade i att utbyggnaden av Vellinge bredde ut sig över
större ytor.
Utbredningen nådde sin topp under 70-talet då Vellinge
fördubblades i storlek. I centrum genomfördes under samma
tid en modernisering där nya centrumbyggnader och stora
parkeringsytor anlades.
Kognitiv träning vid depression
Depression är en vida utbredd sjukdom. Kognitiv träning skulle kunnavara en kostnadseffektiv och lättillgänglig intervention att bemötasjukdomen i ett tidigt skede. Tidigare forskning tyder på att kognitivträning har effekt på depression och kognitiva nedsättningar. Dennastudie ämnade undersöka om träning hemma skulle leda tillförbättringar av depression, och om dessa berodde på träningen i sig.Fyra deltagare med depressionssjukdomar genomförde träning medPaced Auditory Serial Addition Task (PASAT). Studien hade en n=1-design med för- och eftermätningar, och kontroll genompseudointervention.
PPP - Ethernet gateway RS232 - RJ45 network adapter for an Echelon ?Data Concentrator?
För närvarande läses elmätare av en gång per år, detta leder till att kunders elräkning baseras på ett schablonbaserat belopp. Enligt riksdagens proposition 2002/03:85 skall dock alla elkunder, senast fr.o.m. 1 juli 2009, faktureras efter faktisk elförbrukning varje månad. Detta har lett till en stor marknad för fjärravlästa elmätare som nu är ett måste för att kunna utföra den tätare avläsning som krävs. E.ON ES Sverige AB som är beställare av detta examensarbetet har specialiserat sig på att installera, underhålla och läsa av fjärravlästa elmätare åt nätägare.
Analys och förbättringsförslag för riktkopplardesign
Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.
Det offentliga rollspelet : En textanalys av tre kommuners offentliga kommunikation på Facebook
Aim With this study we want to highlight and analyze the media spin of the PR campaign Miss Skinny by clarifying; a diffusion pattern which covers posts published by bloggers and journalists; a framing pattern from the first audited post to the last; how journalists are influenced by user generated content, and what consequences this may have for the news coverage.Method We have conducted a studied of news posts and blog posts about the Swedish PR campaign Miss Skinny through content analysis, diffusion analysis and mapped direct links between blog posts and news posts.Main result We found that a surprisingly large amount of news postings contained direct links to previous blog posts and that the former media serial no longer can be applied on today's modern media where journalists and other players come together on the converged media arena. .
I etikens gränsland: en fallstudie av fyra dagstidningars bevakande av gripandet av den misstänkte Hagamannen
The aim of this research was to describe how daily papers comply with the ethical guidelines of journalism when reporting on the arrest of a criminal suspect. In order to do this we studied how the arrest of a suspected violent serial rapist was covered by four newspapers, Västerbottens Folkblad, Västerbottenskuriren, Dagens Nyheter and Svenska Dagbladet. The theoretical areas of the study were the ethical guidelines, and other ethical perspectives in the media, news value and general interest regarding news. The research strategy was a case study, and a text analysis was used in order to collect empirical data. Several readings of the newspapers resulted in four themes to analyse: Identifying, to judge someone unheard, show consideration for victims and criminal, the use of sources.
Resurseffektivt bussprotokoll o?ver RS-485
This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
