High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

Fall accidents are a big problem in the construction industry today and stand forapproximately 23% of all accidents. Skanska is a construction company that has avision toachieve zero accidents. Eliminating fall accidents is one step on the way towards theirvision. The state of Skanskas fall safety has been analyzed in this thesis to show whichimprovements are possible in fall safety.A literature study has been performed in which Arbetsmiljöverkets (The Swedishwork environment authority?s) laws and rules, together with Skanskas own rules havebeen studied.

Spannmål med varierande fuktighetsgrad kan lagras i kvadratiska silor med väggelement bestående av korrugerad plåt. Då det lagrade spannmålet ska tömmas har det fuktiga spannmålet en tendens att fastna på väggarna, vilket medför att spannmålet i efterhand måste avlägsnas manuellt. För att slippa denna tidskrävande process monteras en slät plåt på den korrugerade plåten, för att på så vis hindra det fuktiga spannmålet från att fastna. Om samma plåtdimensioner för den korrugerade plåten används då den släta plåten är och inte är monterad kan väggelementen utsättas för buckling. Det här examensarbetet handlar således om hur väggelementen ska dimensioneras för att strukturen inte ska utsättas för buckling.

The aim of this study is to analyse and investigate a rather new field of LIS studies, i.e. link analysis which is a part of webometrics. Webometrics has been described as the quantitative study of web based phenomena drawing on bibliometric or informetric methods. Link analysis has its counterpart in citation analysis within the field of bibliometrics. The questions the study investigates are if webometrics can provide LIS with new knowledge and if there is a place for webometric studies in LIS research.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

The purpose of this study was to compare less experienced veterinarians? subjective assessments of lameness in horses on the lunge. Previous studies on subjective lameness evaluation have mainly focused on horses trotting in a straight line and the results have shown generally low compliance. With a web-based questionnaire, 43 veterinarians assessed 60 recordings that showed both fore- and hindlimb lameness, interspersed with sound horses that were trotting on the lunge in one direction. The horses showed mild to moderate lameness.

The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.

Syftet med denna studie är att undersöka hur musiker ser på begrepp som ljudnivå, musikupplevelse och relationen mellan dessa. Underlaget för studien är sex intervjuer med musiker och ljudtekniker, med och utan hörselskador. Studien byggs på sex kvalitativa intervjuer och är avgränsad till att i första hand behandla detta inom musikstilar vilka är baserade på trummor och bas ? pop/rock, jazz/blues.Studiens resultat visar att parametrar som t.ex. genre, lokal, ljudteknik, ljudtekniker och arrangör har inverkan på det ljud och den ljudnivå som uppnås vid en konsert.Vidare redovisas respondenternas syn på relationen mellan ljudnivåer och musikupplevelse.

Denna uppsats behandlar fenomenet organisationskultur, och undersöker hur organisationskulturen kan ha kommit att förändrats på ett företag i samband med en organisationsförändring i form av ett uppköp. Detta undersöks genom att två valda teoretiska ramverk används, och att aspekter som tid och förändring inkluderas i studien. Studien genomförs i form av en kvalitativ fallstudie på ett enskilt företag, där semistrukturerade intervjuer av anställda gjorts.Uppsatsen syftar till att undersöka hur bättre förståelse av organisationskultur kan erhållas när en kombination av två teoretiska modeller appliceras i samband med att en organisationsförändring har skett, där det både tas hänsyn till interna nivåer och externa faktorer.Studien visade att en rad olika förändringar gällande organisationskulturen har skett efter det att organisationsförändringen har ägt rum. Studien kan sägas ha bidragit till en djupare förståelse för organisationskultur som enskilt fenomen, och hur fenomenet på olika sätt kan påverkas. .

Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.
