Bullerreduktion av hytt på Volvodumprar : Undersökning, mätning och analys

Too high levels of noise lead to various health problems and cost society billions of SEK peryear. In this thesis we have examined a model of the A40E articulated hauler at VolvoConstruction Equipment in Braås. We have tried to reduce cabin noise in an articulated hauler,while also providing a way on how to proceed with a machine when the cabin does not measureup to the sound requirement. The best way to find leaks were with a reference source of model4205 and its speaker HP 1001 from Brüel & Kjaer in the cab and then walk around and listen towhere the reference source was more prominent. In this way, we found that the edges and theplugs were sensitive areas.

Inverkan av föräldrastrategier och föräldrabarnrelation på tonåringens Interneterfarenheter

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.

Undersökning av exponeringsindex för bildplattesystem inför optimeringsarbete

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.

Bulleremissioner från vertikalaxlade vindkraftverk

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

Ungdomars ljudupplevelser i vardagsmiljön

Noise is a growing health problem. People are not always aware of the injuries that noise can cause. The media culture of today has a big influence on teenagers. This is caused by portable music players, computers, concerts etc. The schools are having larg classes and that can cause a lot irrelevant speech during lessons.

Vegetation och ljudmiljö

Landscape architecture is a visual profession, but other senses also affect our interpretation of a place. Sounds can give us a lot of information about an environment, and they are often perceived as positive. Despite this, research about outdoor sounds most often focus on the reduction of unwanted sounds ? noise ? but the absence of noise does not result in a good soundscape. To accomplish this, sounds we appreciate are needed.

Håll ögat på detaljhandeln

This study examines retail atmospherics from a reality perspective. The topic "special exposure" has received research interest in the past but it has not been recognized as a critical consideration in the daily retail business. Too many retailers leave assortment decisions to thumb rules or trial and error. The highest aim of this study is in addressing that gap between theory and practice. To catch the attention of the customer is important in supermarkets because most grocery purchase decisions are made at the point of purchase.

Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology

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.

Med siktet inställt på bragd, hinder och hopp : En granskning av handikappidrottens plats i det mediala rummet

Purpose/Aim: The aim of this study is to (1) analyze the amount of exposure disability sports get in Swedens biggest newspaper (Aftonbladet), (2) look at how Aftonbladet portraits disability sports and it?s athletes, and finally (3)  to see if there has occurred any change over time (during the last eight years). Material/Method: The first method used is a quantitative analysis to measure exposure.The second method is a quantitative content analysis which is used to analyze how disability sports are portrait.The third method is rhetorical and is also used to analyze how disability sports are portrayed. Main results: The study has shown that disability sports get very little exposure in Aftonbladet. The articles in the newspaper that cover disability sports are portrayed from a personal point of view without much focus on the athletes achievements regarding his or her sport.
