Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.

Inom utvecklingen av de flesta typer av datorsystem används datormodeller för att strukturera lagringen och användningen av data. Likaså finns det flera olika datamodelleringsmetoder att välja bland för detta ändamål. I samarbete med ett företag har en fallstudie genomförts med syfte att undersöka hur agiliteten i två av dessa metoder påverkar utvecklingen av ett Data Warehouse (DW).  De två datamodelleringsmetoder som undersökts är Data Vaulting och Hyper Agility och arbetet har fokuserat på att undersöka skillnaderna mellan dessa när det gäller mängden ETL-kod som måste skrivas, funktionaliteten i datatransformationerna, möjligheten till att uppdatera systemstrukturen samt den totala kostnaden för utvecklingen av DW-lösningen. Inom ramen för fallstudien har en litteraturstudie genomförts och kombinerats med material från sex intervjuer, där respondenterna varit konsulter såväl som företagsrepresentanter.

I am a glassblower and I am a woman. In this project I've been working with alternative representations of the female body, muscles and technology. Mouthblown objects contains traces of body and form representations.I've been using muscle sensors to collect data from my arms while I blow glass. A special has made 3D-models from the collected data and I've blown these viritual objects in glass.My work is based around issues like: What happens when I measure my muscles? Am I (and my process) affected by the data gathering? How can I create alternative representations of the female body? What is the relation between glassblowing, the objects, body and gender?.

The purpose of this study was to examine the routines of performance related pay systems in two Swedish municipal upper secondary schools. A second purpose was to examine what data was included for evaluation of a co-worker?s performance and how a principal collects data. The purpose was also to examine a principal and teachers´ view of performance related pay systems and if it was possible to note an agreement. Principals have been interviewed and teachers have answered a questionnaire to fulfil the purposes of this study.The study shows that the municipality had a good routine that included individual discussions with co-workers about their salary and had fixed municipal criteria.

Bakgrund: Produktutvecklingsprocessen har på senare tid kommit att ses som en strategisk aktivitet som är avgörande för företagets överlevnad eftersom produktens utförande och kostnader till stor del fastställs innan tillverkning påbörjas. ?Target Costing? har sitt ursprung från Toyota i Japan och är en metod för strategisk kostnadsstyrning som har vuxit fram för att tidigt styra kostnader. Metoden används för att integrera kostnadsstyrning i produktutvecklingsprocessen i samstämmighet med kundkrav och företagets egna vinstkrav.Syfte: Syftet med studien är att beskriva och analysera hur ?Target Costing? används i produktutvecklingsprocessen på Volvo Construction Equipment i Braås för att ge kunskap till nya potentiella användare.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Idag väljer många företag och kommuner att placera data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig data då de ställer sig tveksamma till molnleverantörernas hantering av data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Det här examensarbetet undersöker hur en databaslösning kan utformas för simuleringsbaserad ruttoptimering. Då det finns få relaterade arbeten inom ämnet syftar detta arbete till att undersöka hur en lämplig databaslösning kan utformas och ge riktlinjer för detta. Databaslösningen innefattar både lagring av data samt åtkomst och hantering av data. Då simuleringsbaserad optimering ofta är avancerad innebär detta att en stor och komplex mängd data måste hanteras. Simulator och optimerare använder denna data under själva optimeringsprocessen, vilket ställer krav på effektivitet och snabb åtkomst. Arbetet är inriktat på ett praktiskt problem där sophantering av containrar simuleras och optimeras.

Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.

Background: Once upon a time the most important resources in an economy were tangible goods. Historically, Swedish company culture has been dominated by engineering and techni-cal innovation has been the focal point. Today, Intangible values drive product development and form a company?s differentiation. Intangibles have therefore become the most prominent resources in a company.

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.
