Arbete över företagets gränser : En studie av organisationstillhörighet för konsulter i bemanningsföretag
Since the late 1900s, the consultancy has taken a firm grip on the labor market. The consultants' work profile has been secured through agreements such as guaranteed wages. The collective has been shattered as well as higher demands are required of the employee. This results in higher work demands, workload, a reduced staffing resource and hopeless wages which can lead to health problems and depressions. Previous research shows that consultants find it stressful to be associated with two companies and some clients can also point out consultant through different attributes.
Barn med lässvårigheter och bibliotek en användarstudie om några barns erfarenheter och upplevelser av bibliotek.
The purpose of this study was to examine how some children with reading problems experience and use libraries. The main problem was: How do dyslectic children experience and use libraries and how do they handle their reading difficulties when using libraries? The questions at issue were: 1. Do children with reading problems use libraries, and if so how? - in which purposes do they use libraries? - which materials and services do they use? - why dont some children use libraries? 2.
Full duplex Konferenstelefon
Denna rapport analyserar ekosläckning för en full duplex högtalartelefon. Systemet bygger på en LMS-algoritm som har implementerats på en TMS320C3 1 signalprocessor. Arbetet har gått ut på att undertrycka ekon genom utnyttja så mycket som möjligt av processoms kapacitet. Möjligheterna för att två eller fler personer skall kunna tala med varandra på att ledigt sätt genom en högtalartelefon påverkas mycket av de ekon som finns i systemet. Högtalartelefonens mikrofon fångar upp ljudet ifrån sin egen högtalare och skickar detta ljud tillbaka genom telefonnätet.
Bonden i Graven Bredvid - En osteologisk studie av den medeltida befolkningen i Norra Nöbbelöv och deras skador på skeletten
This paper is the result of an osteological study of the skeletal remains uncovered during an archaeological excavation of the medieval cemetery in Norra Nöbbelöv. The purpose of the study is to compare the material from the rural site (Norra Nöbbelöv) with materials excavated from the old medieval graveyards in the city of Lund. The aim is to try and shedsome light on the question of whether there is any difference in the occurrence and frequency of fractures and osteoarthritis in the materials compared. The first section of the paper consists of a short historical background of Norra Nöbbelöv and Lund, a chapter on ethics, general results of the analysis and the methods used. Thissection was co-authored by Ulla Zagal-Mach and Åsa Strandh.
Scenerier i glas - ett projekt om mönstermoduler
The present project was initiated with the aim to create pattern modules for use in public environments. My intention was to let the properties, of the specific materials used, have a marked influence on the realisation of the final form. I also wanted to find a material, which is suitable from the perspective of sustainabilityand possibilities to create modules from it. The work was initiated with a study of some candidate materials and many sketches before I finally made my choice. My decision was clear after a visit to the company Glasfabriken inKalmar.

Denna rapport analyserar ekosläckning för en full duplex högtalartelefon.
Systemet bygger på en LMS-algoritm som har implementerats på en TMS320C3 1
signalprocessor. Arbetet har gått ut på att undertrycka ekon genom utnyttja så
mycket som möjligt av processoms kapacitet.
Möjligheterna för att två eller fler personer skall kunna tala med varandra på
att
ledigt sätt genom en högtalartelefon påverkas mycket av de ekon som finns i
systemet. Högtalartelefonens mikrofon fångar upp ljudet ifrån sin egen högtalare
och skickar detta ljud tillbaka genom telefonnätet. Utan någon form av
ekokontroll uppstår ett irriterande eko av sin egen röst i telefonen. Ju längre
fardröjning som telefonnätet tillför, ju mer irriterande blir ekot.
Konventionella högtalartelefoner använder röstaktivering av mikrofonen för att
bli av med ekot.
Effektivisering och produktivitetsökning i produktionsflödet av Hammarhäftare på Isaberg Rapid AB
AbstractThe market?s demand to purchase more cost effective products is continuously increasing. The producers are forced to become more efficient and flexible with resources to produce high quality products at a low cost in order to maintain or increase market shares. With this in mind Isaberg Rapid AB is requesting a project to increase efficiency in the assembly cell of hammertackers. The company has found in Kaizen-events that there is a potential of efficiency improvements in the assembly group that has not been achieved.The objective with this paper is to identify the major factors that influence the efficiency in the assembly cell for hammertackers.
Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation
The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas
digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards
to relevant system parameters. The purpose was to evaluate if the technology is a possible solution
to reduce deforestation and support Malawi in climate change mitigation and adaptation.
The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine
which one was best suited to utilise as a digester substrate. After the installation, measurements of
temperature, pH, biogas production, biogas composition and system functionality were made.
The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Världen som vi ser den : En undersökning om hur vi läser trovärdighet i andefotografier
Denna undersökning handlar om olika sätt att titta på och uppfatta fotografier. Frågeställningen tar upp hur vi läser av trovärdighet i ett fotografi. Undersökningen tar upp olika synsätt och faktorer som kan påverka fotografiers trovärdighets som till exempel hur fotografiets teknik och dess koppling till det avbildade påverkar hur vi ser på fotografier. Eller till exempel hur möjligheten att bearbeta fotografier påverkar trovärdigheten. Temat i undersökningen är fotografier på spöken och andar.
FRISTADS ? Supply Chains, från tråd till arbetsbyxa
The Swedish Textile industry has since the beginning of the 70-ties moved their production to countries with cheap labour further and further away. The production in the Baltic countries and Asia has become reality for many Swedish manufacturing companies. With today?s technology the communication with remote countries has ceased to be a problem. The difficulties have instead turned out to be more focused on transportation of goods and just in time deliveries to Sweden.
Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012
This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme
In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.
3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser
The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).
