Utveckling av en dynamisk Simuleringsmodell av en skotare
The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.
Pedagogiskt arbete på Bror Hjorths Hus : invandrargrupper samt skolklasser.
The house of one of the most prominent Swedish artists of the 20th century, Bror Hjorth (1894-1968), was turned into an artists-museum and opened to the public in 1978. It has since the start held pedagogical activities and during the years developed its own pedagogical approach.I have studied the museums pedagogical work from two perspectives; visiting groups of immigrants and visiting groups of schoolchildren, in search of answers to the questions; can art be used as a way to integrate immigrants into the swedish society, and can artmuseums be a resource for schools?This essay contains my observations, conclusions and theories as well as general facts about Bror Hjorths House..
Byggnadsarbetarens syn på att bli involverad i projekteringen : En intervjustudie i byggprojekt
Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews. The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.
Konstruktion av efterbehandlare
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Chefers identitet och identitetsskapande: en studie av chefer i offentlig verksamhet
The aim of this study was to gain a comprehension of managers experience of their identity and their construction of identity in the work sphere. 14 semi-structured interviews were performed with managers in the public sector. The interviews were analyzed from a hermeneutic approach. The results showed that the managers´ experience of their identity and their construction of identity were full of nuances and was characterized by a being and a becoming. The managers had several social identities at their disposal, which were brought to the fore due to the situation.
Förstudier av kommersiella fastigheter : En analys av arbetssätt ur ett projektledarperspektiv
This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.
Vägen till produktionsanpassade arbetsinstruktioner
The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ?s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned.
Program för lakvattenrening för Lilla Nyby
Byggsektorn står för en stor del av energi- och materialanvändandet i Sverige idag och för att verka mot en mer hållbar byggsektor startades Bygga-bo-dialogen. Ett av dialogens åtaganden har varit att ta fram ett klassningssystem för byggnader; Miljöklassning av byggnader. Andra sätt att åskådliggöra produkters miljöbelastning är miljömärkningar såsom Svanenmärkning. Denna rapport tillämpar båda dessa sätt på ett småhus som kallas för Eco House och ska peka på skillnader och likheter mellan systemen. Svanenmärkning och miljöklassning ska utföras på Eco House för att se hur ekologiskt det egentligen är och förbättringsåtgärder ur synpunkten att göra Eco House mer ekologiskt skall undersökas.
Vinterträdgårdar ur ett byggperspektiv : En undersökning om byggandet av vinterträdgårdar
The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.
Sensorsystem till hinderhanterande robot
The projects goal is to construct and program a robot that is controlled from a computer but also have an obstacle handling function that allows the robot to navigate around the object by itself.The robot is a simple construction and the number of components and functions is kept at a minimum. A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..
Utvärdering av BeWi Byggsystem
The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.
Personsäkerhet vid väderskyddsbyggande : En kartläggning över dagsläget och problematiken med frånvaron av föreskrifter i branschen
This paper, Personal safety when working with weather encapsulation constructions, is focused on weather encapsulation constructions and how the absence of Swedish standards and regulations is affecting the safety for the workers. The usage of weather encapsulation construction is increasing in Sweden therefore the needs for standards and regulations are becoming more and more urgent. The risks involving the rising and the demolition of the weather encapsulation construction and when the construction is transported along its rails are treated in the paper. Since there are no regulations companies have had to solve the safety issues without instructions, the paper regards how the companies have solved this problem without the support of formal institutions..
Klistret i klustret : En undersökande studie av ansamlingen av GIS-relaterad verksamhet i Gävleregionen
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Det desillusionerade sinnets sökande efter kunskap : En berättarteknisk studie av tre noveller av Edgar Allan Poe
En berättarteknisk studie av "Ligeia", "The Tell-Tale Heart" samt "The Fall of the House of Usher". Studien fokuseras till kunskap respektive destruktivitet och dess funktion i de skilda novellerna. Genom att se till de berättartekniska aspekterna skapas en ny ingång till förståelsen för novellerna och en ny grund för en kompletterande motivanalys. De tre novellernas narrativa framställning och strukturella uppbyggnad skiljer sig men delar vissa gemensamma grepp vilket möjliggör för vidgad förståelse av novellerna..
