Ethernet-baserat interkommunikationssystem för militära fordonssystem
The result of this master thesis report describes the advantages and the drawbacks that will arise when implementing an Ethernet based intercommunication system in military vehicles. The report presents a possible solution and describes how different sound applications will be implemented into the suggested solution. The report show that IP LAN in vehicles leads to more advantages than drawbacks. The main advantages are that all kind of media can share the same LAN and that there is a lot of knowledge of this technique in the civil area. The main drawback is about delay.
Betongbjälklag med limmad matta : olika behandlingars effekt på alkalitet, fukthalt och emissionsbildning
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).

Trafikverket has a range of different rights that are linked to its properties. There are rights that work in favour of Trafikverket?s property as well as against them.
HTML-ramverk i praktiken : En studie av HTML-ramverk från utvecklarens perspektiv
This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..
Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
Utveckling av priset på bostäder i Kina
Under de senaste 30 åren har Kinas ekonomi utvecklats snabbt, vilket hänger väl ihop med landets fastighetsutveckling. Sedan den marknadsinriktade bostadsreformen 1998 har Kinas bostadsmarknad haft en snabb tillväxt med en kraftig prisökning under de senaste fem, sex åren. Denna uppsats har syftet att undersöka de kinesiska bostadsprisernas utveckling och utforska de faktorer som drivit bostädernas prisutveckling. Med insamlade årliga data från Kinas National Bureau of Statistics för perioden 1995-2010 genomfördes grafiska analyser och ekonometriska analyser. Studiens grafiska resultat visar att bostadspriset har en stabil utveckling under perioden 1995-2004.
En jämförelse av hästens tidsbudget och dygnsrytm : frilevande och i stall
Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.
Finansbubblor & babybooms : - en studie av sambandet mellan ekonomiska faktorer och fertilitet i Sverige 1960-2008
Variations in fertility have caused a problematic situation in Sweden among other European countries. According to the Council of Europe we are facing an economic and demographic challenge, when the baby boomers of the 1940?s are retiring. Economists have for a long time studied the connection between economic factors and fertility, and several studies have found a correlation between business cycles and birth rates. This connection is again of current interest 2008, when a financial bubble bursts at the same time as a baby boom occurs.
SMED implementation vid slipoperation
The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.
Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån
WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.
Att mäta effektivitet i utvecklingsarbete : En kartläggning av förutsättningarna på Saab Aerosystems
Ökad kunskap och kännedom om sin organisations prestanda är något som alla företag eftersträvar. Att kunna prediktera vilka resurser ett utvecklingsarbete kräver är en förutsättning för att kunna genomföra ett bra offertarbete. Dessutom krävs prestandakännedom för att kunna sätta mål för det interna målstyrningsarbetet. Kännedomen uppnås genom ett etablerat mätsystem, som innefattar insamlande och användande av mätdata, det är inom detta område som vårat examensarbete har sitt fokus. Närmare bestämt belyses framgångsfaktorer vid implementationen samt hur användandet av mätdata bör gå till.
Framing och epidemier : En studie av framing i relation till fiktiva och reella epidemier
The present study aimed to replicate Tversky & Kahneman's' survey of 1981 The Asian Disease Problem. A survey was conducted on the Internet (N = 200). An identical problem was added, yet with The Swine Flu as the disease. This was done to be able to investigate if there are any order effects, and also if it matters whether the mentioned disease is fictional or real. The results show the same results as Tversky & Kahneman already noted; positively and negatively framed problems generate different responses from the participants.
INVOXICATED. En interaktiv lek med ljud
Invoxicated is an interactive play sculpture where children can explore the wonderful and playful opportunities of sound. Talk into one end of the sculpture, and the sound will travel through the sculpture and come out in the other end. On its way, the sound gets distorted by a number of sound effects. By bending the sculpture?s body, and pressing the sculpture?s buttons, the sound effects gets altered in real time.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.
Hejoppa hejopp! : En musiketnologisk studie av musikrepertoar och dess tradering inom lajvkulturen
The aim of this essay is to study and show the contents of the music repertoire that is used in live action role plays in Sweden and study how this repertoire is spread between participants in the culture of live action role playing.Four informants have been chosen and interviewed, three men and one woman of different ages from different places in Sweden. They have all been practicing live action role playing for some years.Some of the conclusions that can be drawn from this study is that the participants of this hobby culture value music that feels old and contribute to the illusion of another world and time. The music repertoire of the live action role playing culture is filled with this music that gives the participants associations in line with the illusion. That is more important than the real age of the music. Another interesting conclusion is that the participants learn and spread the melodies verbally to each other and only the texts spread on the internet..
