Analys av sprickdetektion vid automatisk avsyning av granvirke : med avseende på sprickors bredd, längd och djup

Examensarbetet syftar till att hitta samband mellan ytliga sprickor hos virke, i form av dimensioner och karaktärer, som dagens maskinella avsyningssystem inte klarar av. Tyngdpunkten i projektet har legat på att identifiera eventuella samband mellan verkligt djup hos sprickor och de ytliga sprickmått som kan uppmätas med automatisk avsyning av WoodEye. I huvudsak har projektets praktiska undersökningar gått ut på att bestämma sprickors ytliga dimensioner, djup, typ och position med hjälp av automatisk avsyningsutrustning (WoodEye) samt genom manuell uppmätning i ett antal itusågade sprickzoner. Det provmaterial som använts i utförda försök och som legat till grund för efterföljande sprickanalyser har varit av sådan karaktär att det kunnat jämställas med konstruktionsvirke som normalt sett hållfasthetssorteras enligt europasstandard SS-EN 14081-1.I projektet har 568 sprickor, fördelade över 8 olika spricktyper, analyserats. Av erhållna resultat har det konstaterats att störst respektive minst medelbredd uppvisades hos kådlåpor respektive kantsprickor, störst respektive minst medellängd uppvisades hos splintsidesprickor respektive kådlåpor, samt att störst medeldjup uppvisades hos fäll-, kap- och stormsprickor.

En jämförelse av energiåtgång och emissioner för olika persontransportslösningar i Stockholm stad

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Snabbt, säkert eller skönt? : Cyklisters preferenser i trafiken

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

DV01 / Ett cykelkoncept

DV01 is a bicycle concept aimed towards a contemporary target group, that considers the bicycle to be both a convenient means of transportation and a product with a high aesthetical value. A bicycle is for many people something that you attach to your own personal style, were not only the bicycles function but also its appearance plays a crucial role. It is also a product that consists of many different components and parts, which all affect the overall impression. The focus of the project has therefore been about finding a balance in the design. When form and function interact in a successful symbiosis, the result is often that the product may last longer and are more loved by its users..

Tätortsnära skogsrekreation : fallet Mösseberg i Falköpings kommun

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

Modeflugor inom transportsektorn

During the time I've attended the programme to become a Transportation manager, I've been presented with quite a large number of different words. My purpose with this paper is to take a closer look at them, and see if they're sustainable concepts. This paper will be a literary study, and be on a wholly theoretical level. After a thorough examination of the various words, I've come to the conclusion that these words that I've chosen aren't just fad-words. They're going to be around for quite a while, this due to the fact that they're based on good ideas from the get-go.

Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

Ett delsyfte är också att undersöka om det finns någon skillnad i arbetssätt gällande miljöfrågor beroende på om verksamheten är offentlig eller privat.Metod:.

Trädetaljer i exteriör arkitektur : En rapport om hur arkitekturen kan tillåtas framhäva trä som byggnadsmaterial i utvalda exteriöra detaljer för ett äldreboende med massiv trästomme

Arkitektfirman Kolman X Boye Architects har fått uppdraget att upprätta bygglovshandlingar för ett äldreboende. Det är ännu ej bestämt i detalj hur byggnaden skall uppföras men beställaren önskar att byggnaden uppförs i träbyggnadsteknik. Äldreboendet projekteras för 54 stycken lägenheter fördelat på sex stycken våningsplan och en total bruttoarea på strax under 6000m2. Ingen lika hög träbyggnad med denna verksamhetsklass avseende brand har tidigare uppförts i Sverige.Vår uppgift och utmaning i detta arbete har varit att reda ut problematiken kring projekteringen av exteriöra detaljer för höga hus i trä. Utifrån kända problem avseende brand, akustik och fukt har sedan ett antal detaljer som påverkar det estetiska uttrycket projekterats.
