Anläggningsbranschens syn på personcertifiering - ? en byråkratisk pappersprodukt eller ett verktyg för att säkra kompetensen?

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

Optimering av informationsinsamlingvid prototyptillverkning

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Bör Systembolaget visa vägen till hållbarhet? : En aktörsanalys av Systembolaget och deras möjligheter och skyldigheter

 I dagens samhälle är den rådande normen baserad på marknadsekonomi. Systemet bygger på att konsumenten vill ha så mycket för sina pengar som möjligt vilket leder till att produktion med hög effektivitet gynnas. I Sverige har vi antagit vissa riktlinjer och regler för att företagens effektivitet och vinstintresse inte skall gå ut över miljön eller de anställda. Regleringarnas syfte är att ? till så stor utsträckning som möjlig ? bidra till att produkter inte framställs under oetiska förhållanden för vare sig människor eller miljö.

MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Långa skuggor med shadow maps

Skuggor i 3D-miljöer är ett mycket efterforskat område, och detta arbete koncentrerar sig på shadow map-algoritmen. Det finns ett problem med denna algoritm, för då en shadow map projiceras på en yta som är större än sig själv så bildas stora trappstegseffekter, vilket kallas aliasing. Problemet som har undersökts är hur olika shadow map-algoritmer i en miljö med långa skuggor beter sig, där ett minimerat antal artefakter så som brus och aliasing är synligt. För detta undersöktes Percentage-Closer Filtering (PCF), som är en variant av shadow map, med olika samplingstekniker ? och även en vidarebyggnad med Percentage-Closer Soft Shadow (PCSS) implementerades.

Biogasinvesteringar i Linköping : samhällsekonomiskt lönsamt eller inte?

Since some years Linköping has invested in biogas production, mainly from offal's, residuals from food industry and manure. The municipality goes for biogas in the local traffic and in all transportation. It is also possible for private car owners to run their cars on biogas. The purpose of this essay is to perform a cost-benefit analysis and examine if the project has been beneficial from a social point of view. The effects have been identified, measured and monetarily valued. The essay is limited to include the year of 2006 only.

Att känna sina elever : Fem lärares förhållningssätt till att undersöka förkunskaper hos elever med migrationsbakgrund

This study aims to give an account of five teachers? views and understandings of second language (L2) learners? previous knowledge, as well as, their linguistic and cultural backgrounds. This is carried out by the means of qualitative interviews, where the sampling consists of five primary school teachers at various schools. The findings are presented and analyzed using a thematic analysis. Furthermore, the study indicates that teachers in general have a positive attitude to learning more about their L2 learners? prior knowledge and backgrounds, both for the pupils, as well as, their own sake.

Psykosocial arbetsmiljö : kommunikation och trivsel i industriella arbetslag

Relationships and trust between humans create the psychosocial working environment. This is a basic human activity and is communicated in a continually ongoing process. Conciseness about the value of trust and social capital motivates the need for work, with threats to communication, being conflicts and noise. This can create greater trust in the workplace as a whole, as well in the working team. Scientists are increasingly interested in these social relations in the working environment; there are profits, both for production and in terms of individuals2019 well being, in shifting the focus away from a purely production-oriented, economic perspective.

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.

Den militära nyttan med geografiska informationssystem kopplat till eldlednings- och observationsinstrumentet vid precisionsbekämpning.

I takt med Försvarsmaktens ökade engagemang internationellt och det faktum att alla insatsförband inom Försvarsmakten ska kunna verka på alla konfliktnivåer och i en urban miljö kommer nya krav och behov på bekämpningsförmågan att uppstå avseende precisionsbekämpning.Med hjälp av ett GIS kopplat till EOI:et vid en insats i en urban miljö kan en rad vinster erhållas för att stödja artilleriet vad avser precisionsbekämpning. Exempel på sådana områden är: målverifiering, justering av målkoordinater, lägesuppfattning avseende målets närmiljö, redovisning och presentation av verkansområde inför en insats för dimensionering av verkan..

Bostäder vid stränder och järnvägar - risker, attraktivitet och konflikter. Fallstudie: Öbacka strand i Umeå kommun.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

The new law has resulted in that the production goal is equal to the environmental goal within forestry.

Implementering av lean i ett gjuteri med låga volymer och hög variation

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.
