Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Kraftindustrin arbetar oavbrutet med att försöka höja och upprätthålla dammsäkerheten i Sverige. Erosionsskydd för fyllningsdammar skall dimensioneras och utformas så att de medverkar till en god dammsäkerhet. Vid dimensionering och projektering av erosionskydd måste vågberäkningar utföras för att bedöma angripande våglast. I Sverige genomförs dessa beräkningar utifrån kraftföretagens riktlinjer för dammsäkerhet, RIDAS. Uträkningarna och bedömningar av våglasterna är ur dammsäkerhetssynpunkt viktiga eftersom de ofta avgör erforderligt fribord.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by Spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

Förhöjda halter av endotoxin i blodet förekommer ofta vid sjukdomen pyometra hos tik och kan orsaka många av de allmänna symtom som ses vid sjukdomen. Endotoxin Activity Assay (EAA) är en ny, snabb metod för mätning av endotoxinaktivitet i helblod. EAA-metoden är anpassad för humanpatienter, men har testats i forskningsstudier och visats fungera även för hundar och efter viss modifiering också för hästar. Två olika apparaturer från finns att tillgå för EAA (från Spectral Diagnostics Incorporated). Den apparatur som utvärderas i den här studien har aldrig tidigare testats på djurslaget hund.

The goal with our research has been to describe how often and in what way female athletes are represented in the sport section in Sweden?s biggest evening newspaper Aftonbladet. The material we?ve used are the newspapers that we collected during two weeks in 2008, the 3rd of November to the 9th of November and the 11th of November to the 17th of November. We?ve conduced two qualitative researches ? a text analysis and an image analysis ? and one quantitative analysis on our material.

The aim of this study is to analyse and investigate a rather new field of LIS studies, i.e. link analysis which is a part of webometrics. Webometrics has been described as the quantitative study of web based phenomena drawing on bibliometric or informetric methods. Link analysis has its counterpart in citation analysis within the field of bibliometrics. The questions the study investigates are if webometrics can provide LIS with new knowledge and if there is a place for webometric studies in LIS research.

I framtiden kommer multiplexad detektion att spela en central roll inom kliniskt bruk. Detta för att utvecklingen av riktad molekylär medicin är på uppgång och kräver studier av interaktioner mellan makromolekyler. Inom forskning används fluorescensmikroskopi för multiplexad detektion men inom kliniskt bruk föredras det att studera preparat med ljusfältsmikroskopi. Dagens problem med ljusfältsmikroskopi ligger i att det är svårt att detektera flera olika markörer samtidigt, multiplexning. Olink har lämnat en förfrågan på en ny testbar metod för multiplexad ljusfältsavläsning (bilaga 3).Bland dagens metoder för multiplexad analys har NuanceTM som baseras på liquid crystal tunable filter (LCTF) och SpectraLamp som baseras på agile spectral light source (ASLS) studerats och utvärderats.

English title: "Motivated system technician wanted" A study of the relationship between two parts in job advertisements". The purpose of this study is to describe the linguistics of job advertisements. The focus is on discursive practice and how the relation between employer and the proposed employee is created through the process of communication in job advertisements. The method concists of two parts: A critical discourse analysis using the three dimensional model for critical discourse analysis by Fairclough and a text analysis inspired by Hellspong & Ledin. 40 job advertisements were examined and the analysis revealed that the majority belongs to the category traditional job advertisement and a minority uses more than one discourse.

The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.

In this thesis I based on Fowler?s method of syntax analysis construct a flow scheme which I then use to make a syntax analysis of former State Secretary Lars Danielsson?s statements, in his autobiography, regarding his responsibility in the Swedish government?s management of the 2004 Indian Ocean tsunami disaster. The focus of the flow scheme is how grammatical constructions can be used in the interest of rhetoric?s to on the syntax (non-explicit) level of the text indicate and place responsibility with or outside of involved individuals. The main conclusion of the syntax analysis performed is that Danielsson in his autobiography in fact does not use very many of the constructions described in the flow scheme, whereby it can be concluded that the syntax analysis in this case wasn?t so ?revealing?.

This essay contains a comparative analysis of Erik Olin Wrights Marxist class analysis and Michael Hardt and Antonio Negris post-Marxist class analysis as presented in their books ?Empire? and ?Multitude: War and democracy in the age of Empire?. I discuss the shift in analytical focus from state level to global level that Hardt and Negri's analysis represent and the ensuing relevance of this for contemporary class analysis. The essay also address the challenge and implications posed to class analysis by the ever increasing economic globalization, from a material production to an ever growing immaterial service economy and the decrease in state power in controlling capital and labor movement. I propose that analytical understanding of class conflict help us to a better understanding of the mechanisms and dynamics that generate social and economical inequalities and that an updated Marxist class analysis still have much to contribute to our understanding to how these issues not only shape our society but also our capacity to counteract them..
