Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län
Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden.
This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation.
The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.
Mobilt internet för skogsbruket med CDMA2000 i450 MHz - bandet :
Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.
Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning
The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.
Cellulosa : en alternativ isolering med hänsyn till brand och fukt?
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Vattenjärnhaltens betydelse för mjölkkors hälsa och produktion :
Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.
Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning
The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.
Vägen mot flexibilitet : En studie av Sex Sigma och lean production inom industrin
This paper is about the new methods and metrics used in industry and business today striving for better revenues and larger market shares. It investigates the relations between the old fordistic and tayloristic way of manufacturing and compares it to the models used in industry today for being competitive, seeking to please customers and becoming more flexible. More specific the paper is about if Six Sigma and lean production are the key for succeeding these days. SKF:s factory in Gothenburg and other companies will make an example for how these methods are used in practice.The aim is to try to answer if these systems with inherited tools and methods are the right way to get the flexibility that is needed for being able to deliver the right goods to customers and market. For a company to be flexible decisions must be made fast and needed changes must be able to be done easy and without too large costs and investments.
Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter
The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

growforgold.org : a design proposal for creating productive green space in cities
The aim of our master thesis is first and foremost to win the competition One Prize
- mowing to Growing: Reinventing the American Lawn, announced in USA by the organization Terreform 1, the first of December 2009. Apart from winning the competition we have also tried to reach a deeper understanding of food production today and its future possibilities. Our ambition to present a winning design proposal has to a large extent decided the structure of the entire thesis.
Our completed and submitted design proposal - growforgold.org - is a way of addressing urban food production in a creative way, keeping the sovereignty of
the individual in mind. Instead of presenting a place-specific design solution our proposal aims to create incentives and possibilities for urban farming to take place
anywhere and anytime. Our submission to the competition represents both a tool and a platform which, put in practice, could make landscape architecture happen through the hands of the individual.

This report describes the process of outlining a design proposal for a resource planning tool for TV post-production. A feasibility study in form of a participant observation has been carried out on-site, which has resulted in a requirement specification. Based on the requirement specification, mockups have been created to illustrate the functions and features that a final planning tool should have. In addition to developing a design proposal, an evaluation of the existing resource planning tool Ganttic has been conducted. Ganttic has been reviewed based on how well it meets the list of requirements.
BIM förändrar produktionen
Because society?s demand for quality, efficiency at low cost is constantly increasing, companies are increasingly choosing to invest new methods to achieve these points. Those who manage to find ways to improve their processes are often the companies that have the greatest chance of becoming a winning player in the market. BIM is a new method that can reduce the internal costs while increasing communications between different parties. However there is disagreement about what BIM is and its purpose.
Ansvarsfull produktion ? vägen till kundens hjärta?
Responsible production is a subject of increasing importance for companies toadopt and communicate to their environment and many companies choose to implementenvironmental ? and ethic considerations into their brand strategy. There is, however, adividing line between companies according to what extent they choose to implementresponsible production into their brand strategy and to which extent they choose tocommunicate it to their stakeholders and surroundings. It is the hypothesis about a dividingline that is the foundation for this essay and something we believed could be interesting forfurther analysis.The purpose of our essay is to find out how the brand strategy of a company is affected by theresponsible production and in what extent they communicate it to their environment. Byanswering those questions we hope to find out why some companies communicateresponsible production more actively than others.We have conducted in-depth interviews with the Swedish clothing companies; MariaWesterlind, Zion and Dem Collective and we have through our analysis reached interestingconclusions.
