Framgångsfaktorer för rundvirkesåkerier i Mellansverige :

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

Värdepapperisering av fastigheters hyresflöden

En stor del av fastighetskrediterna på den svenska fastighetsmarknaden kommer under de närmsta åren att refinansieras. Detta i kombination med striktare kapital- och likviditetskrav samt riskkontroll, innebär att fastighetsinvesterare kommer att söka sig till kapitalmarknaden för alternativa finansieringskällor. Detta öppnar upp för värdepapperisering av fastigheters hyresflöden som ett intressant finansieringsalternativ. Värdepapperisering är ett förfarande som innebär att relativt homogena tillgångar eller fordringar med förutsägbara betalningsflöden överlåtes till ett Special Purpose Vehicle (SPV) vars enda uppgift är att äga tillgångarna eller fordringarna. Förvärvet finansieras genom att SPV:n emitterar obligationer eller andra lätt omsättningsbara värdepapper som placeras hos investerare.

Konceptstudie av drivmodul till bandskotare med hybriddrift

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

SammanfattningDetta examensarbete behandlar ett ämne det forskats mycket på de senaste åren, positioneringinomhus. Utomhus är GPS standard men för positionering inomhus finns det än så länge ingenstandard. Syftet med lokaliseringssystemet som utvecklats i detta projekt är att lokaliserapersoner och andra föremål i rörelse i kontorsliknande miljöer. För ett sådant system finns mångamöjliga användningsområden. Ett av dessa är styrning av belysning.Inledningsvis gjordes en litteraturstudie vars syfte var att undersöka vilka teknologier samtmetoder som finns tillgängliga för positionering av personer och objekt inomhus.

Produktionsanpassad tvärkraftsarmering för betongplattor

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Unmanned Combat Aerial Vehicles: Teknik och etik : Ett självständigt arbete om obemannade flygande farkoster och deras militära nytta och moraliska dilemman

Obemannade flygfarkoster har varit omtalat sedan kriget mot terrorn startade 11 september 2001 och det förekommer fortfarande frågor kring hur systemet nyttjas och om det är moraliskt korrekt. Det finns många användningsområden för farkosterna som exempelvis lägesuppfattning, sökandet av försvunna personer, attackuppdrag med flera. Studien undersöker hur farkosterna används inom attackföretag samt den militära nyttan av systemet. Eftersom det finns olika uppfattningar kring hur systemet används i krig och konflikt så kommer studien att redogöra för olika uppfattningar samt att konkretisera dessa.Det moraliska synsättet på Unmanned Combat Aerial Vehicle, UCAV, i konflikt och krig skiljer sig åt. De som talar emot systemet menar att detta i sig är hotet och inte hur det nyttjas.

Flygbilder och fotogrammetriprogramvaran PI-3000 som alternativ vid 3D-modellering för volymberäkning

Projektet har med uppdrag av WSP utförts i syfte att testa och utvärdera ett nytt tillvägagångssätt för volymbestämning av vanligtvis terrestert inmätta objekt. Det nya konceptet innebär att med hjälp av fotogrammetriprogramvaran PI-3000 och, på lämpligt sätt, insamlat digitalt flygbildsmaterial utföra volymbestämningar på objekt av intresse. Detta i syfte att ersätta den normalt terrestert utförda metoden för att göra framförallt tids- och kostnadsbesparingar. I syftet ingick även att jämföra skillnader i resultat av framtagna 3D-modeller och dess beräknade volymer vid användandet av två olika flygburna system. Dessa utgjordes dels av en traditionell variant i form av ett vanligt Cessnaflygplan och dels av en UAV (Unmanned Aerial Vehicle) vid namn Microdrone md4-200.För att kunna utföra jämförelserna genomfördes ett mätprojekt där två stenhögar i en bergtäkt utgjorde testobjekt.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Vägparametrar och deras inverkan på trafiksäkerheten : Fallstudie på länsväg 360 Lycksele - Vilhelmina

The interaction between the driver, the car and the road is essential for the road safety. This case study focuses on the road condition and its effect regarding road safety issues. By studying and isolating the road condition aspect and its contributing role to the accident occurrence, the aim is to explore their relationship, as well as highlight the road parameters that are commonly associated with accident occurrence. This result will be used to develop and increase awareness of the impact of poor road alignment and poor road surface conditions on traffic safety, in order to prevent these accidents from occurring. The road parameters chosen for this study include side friction, cross slope and rut bottom cross slope, road texture, curvature, drainage gradient and rutting.The case study was limited to lv 360 in Va?sterbotten, where all accidents with an unclear cause of the accident were studied, between 2003 and 2012 were carefully studied and assessed based on the condition of the road at the time of the accident.

Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Framtidens energieffektiva flerbostadshus

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

Effektivisering av produkionsflödet för stora cylinderrör på Företaget AB

 This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.

Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia

Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity. Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.
