Uppföljning av planerat skotningsavstånd med hjälp av geografisk informationsteknologi (GIT)
The cost of forwarding corresponds to about one tenth of the forestry industries raw material cost. This gives a motive to do good follow-ups to get a good overview of the forwarding distance and, thus, enable improvements. Follow-ups are also justified by the possibility to make more accurate calculations of the harvesting costs, if better estimations of forwarding distance are achieved. Today (2009) Stora Enso has GPS and vehicle-computers in most of their forwarders. These are used mainly for the forwarder to follow the tracks of the harvester and for the planning leader to see how the forwarder has been driving within the stand.
Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus
This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.
Lyftredskap för KL-trä - Hantering av horisontella och vertikala element i massivträ
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
Planering av vägupprustning med hjälp av GIS och optimering : en fallstudie på Holmen Skog
The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district.
The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.
E-learning ? en utbildningsmetod och dess nytta
Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing.
Jordbrukets påverkan på Östersjön : en jämförelse av indikatorer för att beskriva näringsbelastningen
The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms.
One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses
from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Tidsstudier i kalvuppfödning :
Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf.
To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Hur kan kostnaden minskas för dörrmiljöer utan att försumma funktionen?
The door and its surrounding, is an important part of all buildings. It often amount to a significant part of buildings total costs. The more demands of functions the largerdoes the costs grow.The purpose of this report is to analyze those demands and how to fulfill them.Another purpose is to examine of which reasons the cost grow and how to avoid it inthe best possible way. The study will be performed in collaboration with Bjerking AB. To define the demands a literature study will also be performed.
Balanserat styrkort : En fallstudie om vilka problem som kan uppstå vid implementeringen av Balanserat styrkort i ett sjukhus.
The Swedish healthcare systems have over the past decades experienced a major reorganization that involves reduction of costs and cuts due to the financial problems that the public health system faced. Healthcare was criticized because it was considered to be bureaucratic and inefficient (Funck, 2007). The solution to this problem was to focus on other measures rather than the economic measures, such as modernizing the healthcare instead of cutting down. Implementing a balanced scorecard in a public sector as a hospital, perceived as failures. This is due to several factors such as communication, knowledge and expected time are not taken into consideration when implementing the scorecard.
Mekanisk integration av en IR-detektor i en Stirlingkylare
The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.
Svält vid akut diarré hos hund, beprövad forskning eller gammal vana?
The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.
