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.

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

The development in electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Women experience, in a vaster extent than men, unsafety in urbanpublic spaces. This is a structural phenomenon, based on unequalpower relations. The theoretical starting-point for my thesis is that howwe choose to express ourselves shape the ways we can think about andunderstand society. In my thesis I study depictions of safety in six ofMalmö city?s action plans and guidelines towards increased safety.

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

Stroke is caused by a bleeding or infarct in the brain and is one of the most common diseases in Sweden today. The purpose of the study was to evaluate if Ronnie Gardiner?s Rhythm Therapy (RGR-therapy) has any effect, regarding motor control and the subjective experienced health related quality of life, on people who have been affected by stroke. The examination group consisted of eight people. The intervention consisted of RGR-therapy once a week during a period of nine weeks.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

ABSTRACTPurpose/aim: To clarify what information is communicated through the PR-firm JKL:s blog, how it is communicated, how it relates to and diverges from the communication theories in point, and what the strategies behind the blogging are. By doing this I hope to contribute to the knowledge on corporate blogging and how it can be used.Material/method: Qualitative textual analysis of ten blog posts published on the JKL Blog and process seeking interview with the person in charge of the same blog.Main results: JKLs? blogging coincides to the most part with business intelligence, with the exception that the information doesn?t relate directly to the company?s? main activities. This is mainly due to that they can?t publish information about their customers or competitors.

The aim of this study is to discuss the diagnosis ADHD as a meaning-making discourse that is something more than just a diagnosis with a set of symptoms. I aim to discuss that the diagnosis is productive and can be seen as a means to control and to comfort individuals. The research was based on a method consisting of an idea analysis and a discourse analysis. I am using both a discourse analysis and a critical ideology analysis as perspectives. These perspectives are also based on a general theory of late modernity.

The purpose of this study is to find out, explore and see how children with neuropsychiatric problems like ADHD/DAMP are portrayed and treated in five fictional children?s books written by writers who all are related to ADHD issues, except for one writer.I have done a text analysis performed on five children?s books which can be found in libraries in most of the libraries in Sweden. The analysis shows varying results between the five books followed by a general conclusion about how children with concentration problems are being presented in these chosen children's literature. The main problematic of this study is to examine how these characters are being represented and treated within the scopes of school, family relations and how ADHD/DAMP symptoms are portrayed. This study focuses on analysing how the actual ADHD/DAMP behaviour is being reflected and better understanding for the reader to understand the symptoms of ADHD.Another fact is what kind of relations these children with neuropsychiatric dysfunctions are portrayed when facing with other persons, such as family and friends and how ADHD/DAMP is affecting them daily basis.
