The consumer today is affected by a considerably larger number of world surrounding factors than she used to be, borders between different cultures and other consumer differences are being erased to a growing extent. The consumer can easily get its inspiration from many different directions which become clear in the common life. We eat sushi for lunch, we?re driving German cars and we?re having dinner with international business partners. The community also exposes the consumer for a more intense noise from offers, impact and marketing.

Detta är en kvalitativ undersökning om icke diagnostiserad ljudkänslighet. Syftet är att skildra den subjektiva upplevelsen av ljudkänslighet hos ljudkänsliga personer. Tolv informanter har svarat på ett frågeformulär rörande sin upplevelse som ljudkänslig och hur detta påverkar vardagen. Studiens resultat visar att faktorer som stress, sömnproblem och starka ljud bidrar till ökad känslighet. Strategier för att hantera ljudkänsligheten i vardagen presenteras.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Den finansiella teorin om effektiva marknader och rationella investerare har allt oftare blivitifrågasatt i takt med att marknaden utvecklats. Realtidskurser, rekommendationer och ryktenpräglar många investerares beslutsfattande och tvingar kanske fram ogenomtänkta beslut.Genom att diskutera och analysera hur riskbenägenhet påverkar investerarnasavkastningsmöjligheter ville jag se om detta öppnar upp möjligheter för så kallade noisetraders och arbitrage traders. Vidare diskuterar jag om marknadspsykologiska effekter kantänkas påverka börskurser över tiden eller om arbitrage traders fungerar som försvarare av deneffektiva marknaden och handlar bort anomalier som de psykologiska effekterna ger upphovtill. Slutsatsen av min diskussion är att investerare inte alltid handlar rationellt och attriskbeteendet hos investerare varierar med deras förväntningar, då riskbenägenheten kan ökavid förlust och minska vid vinst..

Isolation against noise and fire? DurabilityThese are important parameters in the planning and design phase.

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.

Ett digitalt vågfilter av Richardstyp har implementerats i en FPGA på ett utvecklingskort. Sampel kan skickas till filtret och mottas från filtret via serieporten på en dator. Metoden som användes är att en modell av filtret konstruerades i Simulink. Filtret har modifierats med avseende på skalning, brus och stabilitet. VHDL-koden till filtret genererades i Simulink genom att bygga modellen av Xilinx Blockset.

It is always more demanding and the risk for misunderstanding increases when communicating in noisy environments. The confusions and the mistakes that occur when speech is disturbed are very interesting and happens constantly. The purpose of this study was to examine speech recognition results from the test PB S/N +4 and find out which confusions that are made by the normal hearing and by the hearing impaired persons in the speech lists 3 and 4, and also analyse the mistakes from a phonetic perspective. Ten normal hearing and 50 persons with impaired hearing participated in the study. The people with impaired hearing were divided into two groups; DTMV 40 dB HL.The results were compared between the normal hearing and those with impaired hearing.

The purpose of this thesis is to examine the performance of queries that is expanded before translation in comparison with only translation of the queries using a bilingual dictionary, and also to see if the number of terms that was used to expand the queries was of any importance i. e. if many terms from a thesaurus helped or destroyed a query. To answer these questions i used two online thesauri, Rogets thesaurus and Merriam-Webster Online and one printed bilingual dictionary, Norstedts English-Swedish dictionary. Even though the number of examined queries is too small to draw any definite conclusions, the results suggest that expanding using a general thesaurus may have a negative effect on the queries.

Vi lever i en värld där teknikutvecklingen går allt snabbare och till synes exponentiellt och oförtröttligt kommer att fortsätta öka. Hur detta påverkar Försvarsmaktens val av tekniknivå för framtida sensorförmåga för artillerilokalisering kopplat mot operativa krav, interoperabilitet och ekonomi blir extra intressant när radartekniken befinner sig i ett generationsskifte. Beprövad teknik, internationella och militära krav på en artillerilokaliseringsradar ställs mot ny radarantennteknik, svensk forskning och utveckling av Aktiva Elektroniskt Styrda Antenner (AESA).Syftet med denna uppsats är att undersöka huruvida ny teknik är ett nödvändigt tekniksteg för artillerilokalisering eller är "gårdagens" teknik lika bra eller kanske till och med bättre i vissa användningsområden och situationer? Är AESA ett nödvändigt tekniksteg för artillerilokalisering?Metoden för uppsatsen är en jämförande litteraturstudie d.v.s. en kvalitativ textanalys utifrån en given teoriram.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

The study has got three aims. The first purpose is to implement the Newman et al.s rampage theory (2004) in a more dominant European context. In this way, the theory?s strengths and weaknesses can be exposed. The second objective is to look at the motive.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

Syftet med uppsatsen är att förklara vilka kulturella skillnader som finns mellan teammedlemmarna i ett av Saabs interkulturella arbetsteam med utgångspunkt från Hofstedes och Trompenaars kulturella dimensioner.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
