The purpose of this thesis is to investigate the two new phenomena; the pricing model Pay-What-You-Want (PWYW) and the launch of daily newspapers in the iPad. A quantitative study was conducted in order to examine what would happen if the PWYW-model where to be used by a daily newspaper for its iPad product, and what this would signal to consumers about the brand in terms of brand association and brand attitude. Furthermore, we have investigated which of these factors that are affecting willingness to pay in this PWYW-situation. Moreover, a secondary purpose was to test the two possible presentations of the digital newspaper in the iPad; Product and Access ? and how the results differed between these two.

This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.

Företaget Motion Control utvecklar elektronik och inbyggd programvara och de har bland annat tagit fram MultiPos, som är en huvudmus för rörelsehindrade. MultiPos är en MEMS-gyro-baserad datormus. MEMS-gyron används för att känna av huvudrörelser som användaren gör, men det är önskvärt med en bättre signalbehandling, d.v.s.

Norrborns Industri AB in Bollnäs manufactures truck trailers with the brand Parator. One of their trailers is Parator LX 10-20. The trailer is designed to transport hooklift containers with the option to tip loose goods such as gravel, asphalt and seed. The container is mounted on a frame which is placed on the chassis. To reduce weight a redesign of the trailer is needed.

Previous research often includes juridical, political, economical and historical aspects of the Sami population. The research about the Sami women are limited therefore is was important to investigate the living conditions of the Sami women. The purpose with the study was to investigate the living conditions of the Sami women from a culture- and reindeer-herding view in relation to social gender and the majority society. Four individual interviews were performed with women who worked with reindeer-herding in the Sapmi area in north of Sweden. The interview guide was semi-structured and the data were analysed with the phenomenological method Interpretative Phenomenological Analysis, which has a focus on subjective experiences.

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.

Ett program som simulerar signalbehandlingen i ett cochleaimplantat med signalbehandlingsstrategin ACE (Advanced Combined Encoder) har konstruerats. Programmets främsta syfte är att i förväg prova ut inställningar i ett cochleaimplantat och genom detta försöka förutsäga olika användares individuella inställningar. Programmet har validerats med utsignaler bearbetade av Cochlear Limited i deras egenkonstruerade Matlab-modul för forskning inom cochleaimplantat, NMT (Nucleus Matlab Toolbox). Samma insignal som använts av Cochlear Limited har processats av programmet och utsignalerna från detta jämfördes med utsignalerna från NMT. De bägge utsignalerna, producerade med samma inställningar, stämde bra överens. Komprimeringsfunktionen i programmet, som är en vital del av signalbehandlingen, visade sig stämma bra överens med NMT:s komprimeringsfunktion, sånär som på en relativ minskning av värdet vid starka insignaler. Programmet ska nu användas på Cochleaimplantat-sektionen vid Uppsala Akademiska sjukhus för att pröva ut individuella inställningar till användare av cochleaimplantat.

The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.

Varmvalsade HSLA-stål (high strength low alloy) uppvisar normalt en lägre hållfasthet i sista änden av bandet. Denna s.k. ändeffekt har länge varit känd och flera undersökningar har genomförts för att utvärdera hur mycket de sistametrarna minskar i hållfasthet. Materialet som undersökts i detta examensarbete är Domex 700MC. DX 700MC är ett extra höghållfast kallformningsstål och dess typiska egenskaper är: ? Utmärkt formbarhet i förhållande till sin höga hållfasthet.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.

Consumer involvement in the product development process, co-creation, is being practiced by numerous companies. Previous research has investigated how consumer participation in co-creation affects consumer attitude. However, little is known about how co-creation affects the attitudes of the observervers of co-creation. The effect of observed co-creation on consumer attitude should be important when deciding whether to apply co-creation or not, as the observing consumers make up a larger part of the consumer collective than the participating consumers do. The paper at hand aims to investigate how observed co-creation affects consumer attitude and purchase intentions.

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

The purpose with this essay is to study how companies use the repositioning process and identify the risks involved from a business perspective. We have chosen to base our essay on the following research questions:What reasons are there for a company to initiate a repositioning?, What does it mean for companies to implement a repositioning?, What are the risks with a repositioning?We have used a qualitative research method and have chosen to interview six respondents which in various ways are actively working with brand repositioning. Our study has been implemented with and deductive character.The most important conclusion that we observed after implementing our study is that repositioning is a high-risk project. Instead of changing their entire brand image, companies should instead make small changes and revitalize the brand by developing the strength that already exist.
