Det gör ont när stockar spricker!

The aim of this study was to provide SCA Forest Norrbotten District with material to assist in their work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs. The purpose of this study was to find an available method to measure the occurrence of splits directly on incoming timber. The ambition was also to gain some knowledge about possible variations between different logging crews in terms of split frequency. If possible, this information could be used to investigate if certain crews produced more splits than others, and thereby making it possible to provide feedback to the logging Machine operators. The study consisted of two major parts, a literature review, and a practical sawmill study.

Vem styr bostadsbyggandet i Nacka och Södertälje? : Vilka aktörer påverkar slutresultatet?

Who runs the development? A comparative study of the construction of residential buildings in Nacka and Södertälje.The aim of this study is to identify actors involved in the initiation and implementation of residential house construction in two Swedish municipalities. This means who is taking initiative for new residential buildings, who affects the planning process, who finances these new buildings and who builds them. By exploring empiric material from the municipalities of Nacka and Södertälje, the above questions will be answered and by referring to pluralism, growth machine theory and regime theory a link to general theories of political science is made. The results found show that the analysed municipalities have quite different possibilities for acting and that these backgrounds are also important for which actors will take initiative for new residential buildings and which actors will be allowed to state their opinion during the planning process.

Utveckling av tjänster för ett mobilt medium

The mobile revolution is here to stay, and today most people have (at least) one cell phone at home. Some even a PDA (Personal Digital Assistant)as a complement for the simpler tasks at the office, e.g sending e-mail, word processing, browsing the Internet etc. Many business have also given the employees the opportunity to do some of the business tasks inbetweeen customer visits with the help from a cell phone or PDA.Despite all this, the so called Internet connected mobile revolution is often mentioned as a big failure. Maybe because the people in general tended not to use the new technology as much as the companies predicted. This could be because they still haven't learned how it works, or just don't seem to have the need for services provided.After a couple of failures in the development process, almost every cell phone has support for mobile Internet today.

Design och konstruktion av Splitmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Samverkansprocessen : Att skapa värden genom kunskapsbildning

Abstract; Finding needs of knowledge are important for universities but also for operation in the surrounding area. Teacher, student and other organization have to make efforts to create opportunities to develop knowledge. Without cooperate/ cooperation they can loose possibilities to develop valuable knowledge. How do the organization see upon meanings of the procedures of cooperation? How do they work with and for cooperation? What role should the universities play in the development of knowledge in todays community of change? The aim of this study is to create an understanding for the meaning of cooperation procedure by developing knowledge and how it might bring value.My interest in this is to find the means of procedure of cooperation and to create understanding.

Konstruktion av specialmaskin för orientering och positionering av nyckelämnen

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

Sönderdelning av plogtilta med skärknivar :

During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.

Grönområde kontra bebyggelse : grönområdenas förändring i Älta, Nacka kommun

This essay shows how natural areas in Älta, a part of Nacka municipality southeast from Stockholm, been changed quantitatively and qualitative as a result of the increased housing construction in the area. Three issues are discussed. Namely: how has Ältas green areas been changed in sizes and quality in line with the settlement's expansion, what is the reason or the reasons to building of different types of accommodations, what has been and is the operators in connection with building of the different types of accommodations?The essay shows that the green areas has been decreased with over 2 km from 1901 to 2000 and in addition to these areas of approximately 1,1km been converted to a planned green structure. Älta has during the years gone through four eras of building types an era of small family houses ? an era of building one million houses on a national scale ? an era of terrace houses ? an era of sporadic building of different housing types (one family houses, pair houses, terrace houses and small blocks of flats).

Volymsrapportering vid terrängtransport av virke

This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

Mekaniserad ungskogsbehandling för röjning och skörd :

Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees of success. Most attempts have been based on techniques where residual stems are straddled. Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.

Typer av sökfrågor på webben: En effektivitetsstudie

The purpose of this thesis is to examine the performance of different types of queries in the AltaVista query-based search engine. Thirty information needs have been collected from an ask-a-question service on the World Wide Web, which means that they are based on real users information needs. This is done to avoid partiality in the study. The author has invented different types of queries for each and every one of the information needs in accordance with the search syntax available for AltaVista. The types used are Boolean expressions, queries including proximity operators, phrases and queries directed towards a specific field.

Jämförande studie av LEM2 och Dynamiska Redukter

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.
