Distribution of wild boar (Sus scrofa) damage and harvest loss in crop fields
The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.
ENERGI- OCH KOSTNADSEFFEKTIVAMATERIALVAL I VÄRMESYSTEM : En jämförelse av rörmaterial i vattenburna värmesystem
The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.
Utveckling av nytt koncept för positioneringsslid
A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

Flexible working conditions is used extensively in organizations today as a way tocreate flexibility for the employer. Recently we?ve been reading in the newspapersthat this approach is a growing problem and the EU has warned Sweden twice thatabuse of these forms of employment must be stopped. The Government has recentlysubmitted a proposed rule change to reduce the possibility of stacking one temporarycontract after another. Borlänge kommun makes themselves more flexible with theintermittent employments.
Kostnadsvärdering av ökade trafikmängder vid utebliven exploatering: en studie av utvecklingsmöjligheterna i EVA.
Då stora vägprojekt ska utredas genomförs en samhällsekonomisk kalkyl för
att ta reda på hur stor nyttan av projektet blir för samhället. Det kan
vara komplicerat att ekonomiskt värdera de olika ingående delarna samt att
veta vilka parametrar som verkligen ger effekt i projektet. I storstäderna
gör den högre tätheten att andra konsekvenser för ekonomin, miljön,
kapacitetsutnyttjande med mera blir annorlunda än på landsbygden, andra
brister uppkommer i beräkningsverktygen. Utifrån en belysning av de problem
som finns i dagens beräkningsmetod ges förslag till utveckling av
beräkningsverktyget EVA (Effektberäkning vid väganalyser) och Effektsamband
2000 genom att ta fram förslag för hur kostnader eventuellt skulle kunna
hanteras i beräkningarna.
De brister i beräkningsmodellerna som har framkommit gäller bland annat
deras enkelhet i storstadsanalyser och att de inte är flexibla. I
beräkningarna tas inte heller de ökade samhällsekonomiska kostnaderna upp
som uppstår då innerstadsnära bostads- och kontorsbyggen inte blir av.

?Pengarna finns i systemet? : Digitalt bevarande i Sveriges nationella strategi för arbetet med digitalisering och elektroniskt bevarande av kulturarvet
The aim of this two year master thesis is to analyze how digital preservation is presented as a problem in the Swedish national strategy for the digitization and digital preservation of the Swedish cultural heritage. In order to study which assumptions about digital preservation exists within the strategy I apply the discourse oriented methodological tools presented by Carol Lee Bacchi, which focuses on discerning what problem or, rather, representation of a problem exists within a specific policy. This study is a post-structuralist discourse analysis. The main focus of the study is on what assumptions and prerequisites the dominating representation of the problem is based upon and how the representation has evolved. The main material of the study consists of public investigations conducted by the Swedish state, governmental propositions and replies as well as other public documents upon which Bacci's methodological tools are applied.Results show that digital preservation is primarily interpreted as a financial problem as the national strategy and its surrounding documents stress the need of cost-efficient solutions.
Analys och produktionsförbättring på monteringslinan Vensafe
This study is preformed at Westbaltic Components placed in Töcksfors Sweden. Themain target in this study is to make one of the company?s assembly lines better andmore effective.

A good way to do this job easier was toconstruct a visualizing board.
GMO Food Products - The issue of marketing and selling them in Europe.
Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.
Volymmätare för tall- och grankott
This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.

Potentialen av värmebesparing i ett avlopps luftningsledning
This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.
Ekonomiska konsekvenser för skogsbruket vid avsättning av mark för viltvårds- och jaktändamål : en fallstudie på Svenska Jägareförbundets fastighet Öster Malma
The value of game for hunting from a social economic viewpoint is an interesting topic
that is currently being investigated in a Swedish research program. The amount of
damages that the game stocks cause to the forestry is, and has been in focus for a longer
period of time. Something that I saw as missing was an investigation of how much an
active game keeping measure might cost in lost incomes for forestry in terms of reduced
acreage for forest production.
This question was the foundation for this investigation, which purpose is to give
interested persons with decent knowledge of forestry an example of how cost estimation
for forestry resembling the example that is studied can look like.
The measures that has been taken is a felling of forest in different ages on both sides of
a forest dirt road to create increased asset of forage for the game, and at the same time
give hunters that have their post along the dirt road a better chance of seeing passing
animals early and increasing the possibility to shoot good shots. The area, which is a
part of The Swedish Association for Hunting and Wildlife Management estate Öster
Malma, is also used as an example for guests who wish to learn more about managing
ungulates. These guests have now got the opportunity to get information on how big the
costs are for the measures that have been taken.
The main conclusions of this work is that changed timber prices and foremost a change
of interest rate makes big differences on the result of the calculations.
Byggnads- och investeringskostnader : Robotmjölkning eller konventionell mjölkning?
This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south
of Eslöv in Skåne.
While my family for some time have thought about building a new milkingstable with
AMS(Automatic milking system) I decided to compare the AMS with a conventional
milkingstable. We are abit concerned about how many cows we should have in the new
stable. Because of that I calculated with two different number of cows.
I have compared three different types of milking stables:
One alternative is 180 cows milked in a double eigth hearing bone milking stable.
The second alternative is 128 cows milked with two DeLaval VMS-robots.
The third alternative is 171 cows milked with three DeLaval VMS-robots.
One salesman from DeLaval and one salesman from A-betong helped me to get marketprices
on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs
labour is included.
The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program
with predicted costs. The calulations from the program showed that the price in the milkingpit
system was 51 000 sek per cow.
