Busshållplatsers kapacitet : Utvärdering av tillämpbarhet av modell från Highway Capacity Manual 2000 med uinderlag från busstrafik i Stockholms innerstad
Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.
Manligt och kvinnligt missbruk : Livshistorier om vägen in, tiden under och vägen ut ur missbruk.
Alcohol and drug abuse is something that undoubtedly exists in our society today. Our interest in this area was inspired by an earlier study of the influence of socialization on these dependencies. From this we developed new hypotheses concerning men and women?s drug and alcohol abuse. The main purpose of this study was to highlight the experiences and reflections of six women and seven men on their own alcohol or drug abuse.
Utveckling Ulricehamn- om stora förändringar i en liten stad :
The purpose of this thesis is to inquire how a small town can be affected by some planned changes in the physical structure of the town, and how its inhabitants can benefit from those major changes. The town in question is Ulricehamn, and of the four projects considered, two concerns infrastructure. A new railway and a new locality for the major road, today passing through Ulricehamn. The other two projects are run by the local authorities, that is the planning of a modern town park by the lake, and a new public building for cultural purposes. There are no guarantees that any of the four projects will ever be realized, but in the process with this work, they have been considered as already a fact.
Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper
At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.
Dubbskador på Alvestakubb
Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.
En jämförelse mellan fyra olika energisystemlösningar : För ett hus byggt efter passivhusstandard i Karlstad
AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes. The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.
Köpares syn vid förvärv av lantbruksfastighet i Dalarnas och Gävleborgs län
Today's real estate buyers value the purchase different today compared to a decade back. Previously it was the return value that ruled the market. This has created problems when the broker must allocate the purchase price of the property's various elements, because non-monetary values such as forest for leisure, recreation, and the feeling of owing has increased in recent years and an increasingly important part in the valuation process.
The assessed value can be a guide, but is perceived today to be stereotyped to put a fair value at the individual item.
The purpose of this study was to provide the real estate agent decision support and a guide to the likely value of accounting for the purchase price.
The report is written on behalf of LRF Konsult. The result is based on a questionnaire survey which was conducted in June 2014 among all those who had bought a farming property in Dalarna and Gävleborg province mediated by LRF Konsult in 2013.
The report was made with a split to see if the valuation and motives differ between new and previous owners. It was possible to see a big difference in the reason for the purchase, where a large share of new owner bought the land for capital investment, in contrast to previous owners whose biggest group bought for an active use.
At several points it was possible to identify a higher non-monetary value of the new owner from the previous landowner.
Elementkoncentrationer i gran utmed en markfuktighetsgradient :
One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.
SÖDRAs Gröna Skogsbruksplaner : en uppföljning relaterad till SÖDRAs miljömål, FCS's kriterier och svensk skogspolitik
SÖDRA beslutade 1995 att starta ett projekt för att förse föreningens medlemmar med
naturvårdsanpassade skogsbruksplaner. Projekt "Gröna skogsbruksplaner" har som mål att
fram till år 2002 täcka halva medlemsarealen med gröna planer, och har för att nå detta givits
en budget på 50 miljoner kronor. Konceptet med grön plan är ursprungligen skapat av
skogsvårdsorganisationen, men SÖDRA är först med att producera gröna planer i stor skala.
De gröna planerna skall enligt projektets syfte "ge SÖDRAs medlemmar ett verkningsfullt
redskap for virkesproduktion med hänsyn till de miljömål som finns formulerade i SÖDRAs
miljöpolicy". Detta är ett led i det miljöengagemang som på senare år ökat i Sverige.
Kapsprickor och avverkningsaggregat
This study was made for the Swedish forest company Sveaskog because the sawmills they delivered timber to had noticed a high frequency of bucking splits in their products. Coworker Jim Edström at Sveaskog also wanted to know if there was a big difference between different felling heads. The purpose with this study has been to find out the amount of bucking splits and if there is any felling head brand that did a bigger damage that the others.
The study was made in two steps, where the first part was a literary review to find out results and conclusions in earlier studies. The best measuring method to check bucking splits was the known ?trissmetoden?.
Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost
This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.
Etanol : ett hållbart tankande eller ett kortsiktig tänkande?
Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.
Jämförelse mellan renskötsel och betesbaserad fårskötsel
This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.
Teknikutvecklingens påverkan på energianvändning i byggnader under 100 år
Detta examensarbete i energiteknik har utförts på uppdrag av företaget ABB och avdelningen Energy Efficiency under våren 2013. Syftet med arbetet är att ta fram ett underlag för energianalyser där åtgärder kan föreslås och prioriteras efter ålder på byggnader. De typer av byggnader som undersöks är flerbostadshus och kontorslokaler. En road map har tagits fram för att skapa en översikt över de senaste 100 årens fastighetsteknik. Därefter har en analys gjorts över teknikutvecklingens påverkan på energianvändning med fokus på byggnadens ingående komponenter i ventilations- och värmesystem, inom belysning och i klimatskärmens uppbyggnad. Förslag på åtgärder med energibesparingspotential föreslås och prioritering av dessa görs för olika tidsepoker.
Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes
A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.
