Automatisk plastlisthanterare
Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.
Sammanvägda avrinningskoefficienter i rationella metoden : en jämförelse mellan idag och 1970-talet
Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.
Brännkammare för träpulver : Teoretisk analys och praktisk försök
The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..
Skogsentreprenör 2007 : en kvantitativ studie av organiserade skogsentreprenörer i Sverige
SMF Skogsentreprenörerna is a nationwide organisation for Swedish forestry contractors. It has about 750 organised companies with somewhere around 1500 logging machines. These machines perform well over 50% of all yearly landed wood in Sweden. The members of SMF also performs more and more of other functions in Swedish professional forestry, such as soil scarification, planting and pre-commercial thinning of younger stands.
In order to determine what major priorities SMF should focus on in the future a member survey was initialised and carried out by SMF together with Daniel Larsson-Snygg, student at the swedish university of agricultural sciences SLU.
This report presents the result of this survey sent out to all members of SMF. It is intended to answer a number of questions about their entrepreneurship such as:
What different kinds of work do these companies perform? How many machines and employees do they have? How old are the company owners and their employees? What are their thoughts about the future of their business? How well does SMF serve their members needs?.
Bil- och järnvägstrafikens inverkan på inomhusmiljön med avseende på ljud och luft : - I planerade bostäder på Haga
NCC has given us a commission to investigate a planned housing area in Haga, Karlstad, situated close to the traffic route Hagaleden and the railway. The housing area consists of one hundred apartments in five different houses. The houses are linked to each other by balconies with glass panels. A long carport is situated between Hagaleden and the housing area to absorb part of the noise from the road. The design of the housing area is creating a silent backyard.
Lönsam smågrisproduktion : en fallstudie
The purpose with this work is to investigate the cost to produce piglet in a case study
company. The starting point is going to be the agriwise (www.agriwise.org) calculation which
I am going to change and adapt to the case study company. To day the pig market is bad but
we have probably reached the bottom. The market has started to rise. It is no business to
produce piglets today.
Arenabygget, ris eller ros? : en hedonisk prisstudie av kommuninvånarnas värdering av den nya arenan.
This study is an examination of the stadium fever prevailing in Sweden. It is built stadiums in Sweden as never before. The high cost of these constructions end up in the end at the Swedish taxpayers. The study examines through the hedonic pricing of real estate how local residents value the new stadiums. The result indicates that local residents put a positive value in the costly and sumptuous buildings.

Möjliga alternativ för att ersätta direktverkande el i flerbostadshus
I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.
Energikartläggning av Fridhemsskolan 16:2
Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.
Polstjärnan. Ett fastighetsutvecklingsprojekt
Efter att ha ägt fastigheterna benämnda som Polstjärnan, belägna i stadsdelen Lindholmen på Norra Älvstranden i Göteborg, under många år ställs Wallenstam nu vid ett vägskäl. Med byggnader som åldrats och ett område som utvecklas ifrån dem växte fastighetsutvecklingsprojektet Polstjärnan fram.Syftet med arbetet är således att utreda en framtida utvecklingsplan för fastigheterna som är väl förankrad i området Lindholmen och kvarteret Polstjärnegatan-Karlavagnsgatan. Till att börja med ville jag få en bild av Lindholmen ser ut och vad det finns för planer för fortsatt utveckling i området. Därför kontaktade jag Johan Altenius, planarkitekt på stadsbyggnadskontoret i Göteborg och Anna Eckerstig, byggprojekt och verksamhetsansvarig på Chalmers Fastigheter.För att sedan skapa en gällande utgångspunkt för arbetet har flera personer på Wallenstam intervjuats. I dessa intervjuer har de fått ge sin bild av fastigheterna, dess historik och tidigare tankar på vidare utveckling.
Fastighetsutveckling i Farsta. Ekonomisk analys av TeliaSonera-områdets framtid
Stockholm is one of the fastest growing cities in the world. Its population is growing every day and the housing needs are becoming higher. Despite the growth and the need for more houses only a few new housing units are being built every year. Critics argue that if the building rate stays as it is today the development of the city will be very limited since there is no capacity for the city to embrace new incomers.The decision makers in the municipality of Stockholm are planning for large investments in housing units for the coming years up until 2030. There are plans of building approximately 140 000 new apartments to mend the ascending need for new houses.Farsta County is part of Stockholm and lies a few kilometers to the south of the city center.
"Anders Andersson hade eld i sin tjärdal" : en analys av Jonas Åströms dagböcker 1868-1891
"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891
Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.
ANALYS AV FLERBOSTADSHUS : Med inriktning på ytfördelningen över tiden
Currently, there are no clear statistics on how the floor plan and room size in apartment buildings has changed over time since the postwar period. The statistics available is average area per apartment which can be found on Statistics Sweden's website. This report has the aim to increase knowledge about how the Swedish home have changed over time.The questions that the report will answer are:For apartment buildings, how has the living area been distributed since the postwar period?Why has the area distribution changed over time?A survey of the houses built during 1950-2014 was made before questions could be answered. A case study was also made which a total of 90 apartments were analyzed and divided into three eras, the people´s home, the million programme and the neomodernism.
Sekundärnät för lågtempererad fjärrvärme
Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.
