Pneumatiska artificiella muskler : med hjälp av en robotarm

According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

Testsystem för utredning av integrerad styrning för RC-helikopter

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

Informationsdesign + omvärldsanalys = sant? : En studie i hur informationsdesign behandlas som en aspekt av omvärldsanalys

Access to correct and updated intelligence about our environment is in an increasingly degree considered important in the private as well as in the public sector. At Mälardalens University, competitive intelligence as an area of research is closely related to Information Design - a multidisciplinary consideration which goal is to improve the Receiver´s understanding of intended messages. This study was conducted in order to find out how Information Design was representedin different kinds of literature regarding Competitive Intelligence. Also, it describes the main focus areas concerning Competitive Intelligence in the same literature. Through an explorative "pearl-growing" method combined with searches through referrals, 60 different sources provide a broad basis for analysis.

Public Hear Aid

This project started when LIC Audio AB wanted help with development of a hearing aid for public rooms. The problem is that a lot of people suffer from some sort of hearing impairment. In places with a lot of people and background noise the problem becomes bigger and the sound seems to flow together. During the project we found the solution for the problem in the shape of a headphone. The headphone receives a signal from a preinstalled hearing loop.

Musikens betydelse i TV-reklam : En analys av jingel, bekant och obekant musik

This essay examines the communication value of music in television advertising. It studies different forms of music and whether these forms contribute positively or negatively to how television advertising is perceived and remembered. The forms are jingle, familiar song and unfamiliar song. 100 high school students participated in the study through a questionnaire.                      The study shows that music is an important tool that complements television advertisings visual aspects. Music creates feelings, emphasizes aspects of the image and clarifies the advertised message.

Sensorfusion av GPS och IMU för en racingtillämpning

AIMS AB is a Swedish company that develops and sells inertial sensor systems. A new product is under research which basically is an aided inertial navigation system where unwanted drift is eliminated. This can be done by integrating a GPS reciever into the system and fuse measurement data from GPS and IMU. Such a product is useful in racing, where engineers always are searching for the optimal performance and the shortest lap times. Today the only feedback the engineers and mechanics get from their work is the driver?s comments and lap times.

Fattigvården i Kristdala socken 1881-1890 : en studie av en småländsk landsbygdssocken

The aim of this study is to learn about the nineteenth century poor relief system, how itoperated in the rural parish Kristdala during the period 1881-1890, and not least, who was thesupported person? The poor are defined as the individuals that received public poor relief, but in onechapter this definition of poverty is contrasted with a definition based upon tax exemption:inability to pay taxes. Two villages have been selected for intensive study, namely Kroxhult and Calerum, and Calerum is the smaller one. The connection between age and the poverty ratio is clear, and tobe a lodger was especially disadvantageous with respect to poverty. Further the position ofwidow was the most unfavourable among the female poor people.

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark

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).

?Dissociation av igenkänningsminnet med ortogonala variationer av egenskaperna frekvens och celebritet hos personnamn?

Tidigare studier har gett stöd för att igenkänningsminnet understöds av minst två processer: erinring (recollection) och familjaritet. Detta testades i två beteendeexperiment, inom ett Remember/Know paradigm (experiment 1) och ett Ja/Nej paradigm där Receiver - Operating Characteristics (ROC) beräknades (2). I ett påföljande Event - related potentials (ERP) experiment undersöktes vidare distinktionen mellan minnesprocesserna under återvinning. Deltagarna studerade namn med två former av pre - experimentell familjaritet, namnfrekvens och celebritet, vilka kombinerades till ortogonala variationer av dimensionerna. Frekvens operationaliserades som antalet träffar i den nationella telefonkatalogen och celebritet som antalet träffar i massmediala webbsidor.

Kommunikationens betydelse : fallstudie på införandet av balanserade styrkort i Gotlands kommun

This study raises the question how the implementation of the balanced scorecard in the municipality of Gotland has been influenced by the way of communication. A case study is made in the administration of Social-and care management on Gotland. We have been focusing on two different ways of communication. The first one is Shannon and Weavers model where communication is explained as a transmission of a message through a channel to a Receiver. The other one is sensemaking where it is focal to give the information meaning.

Modelering av Wideband : Code Division Multiple Access

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

Automatiskt Nödstopp

In today?s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user.The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.

Kommunikation vid återkoppling : Vad sändaren upplever att den ger och vad mottagaren upplever att den får vid kommunicerade återkopplingssituationer

Syftet med föreliggande kvalitativa studie var att undersöka hur sändares kommunikation av återkoppling till mottagare upplevdes av sändare respektive mottagare. Undersökningsgruppen bestod av åtta deltagare tillhörande två undergrupper, fyra sändare och fyra mottagare där varje sändare hade en arbetsmässig koppling till en av mottagarna. Fokus låg på deltagarnas subjektiva upplevelser av återkopplingssituationer i arbetet och utgick från tre teoretiska teman; kanal, innehåll och tydlighet. Det insamlade materialet analyserades genom en hybrid av deduktiv och induktiv tematisk analys. Resultatet visade att både sändare och mottagare av återkopplingen upplevde den fysiskt närvarande kanalen som den starkaste, effektivaste och mest förekommande.

Gränsland : var går gränsen mellan mig och en fysisk plats?

I have investigated the interaction between man and environment, between my inner reality and a physical place, using a camera as my primary tool. What conceptions do I have and how do they affect how I relate to the outer world? I am not a passive Receiver of the surrounding world. Instead I actively (but usually unconsciously) choose what to take in and how I experience it. If we as landscape architects do not reflect upon our conceptions, they will unconsciously affect our decisions. Only when we accept our experiences as subjective, can honest communication take place. By means of literature studies I have connected my own conceptions with different definitions of place: place as enclosure (location, space), place as inner meaning (genius loci) and place as action (the place-creating process).
