During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Through extensive research it has shown that today?s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today?s market. Besides rising fuel-costs, environmental awareness is very important in today?s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University.

the most obvious problem at Traction today is the in-between handling that demands much time and resources. The reason is that the packages are not designed with handling in mind. Several of the packages of today also have a poor degree of utilization that means there is room for a fewer number of articles. That in turn means more packages, more transports, more storage space and more staff. On the basis of a specification of demands ? which take quality and environmental influence, as well as transport, handling and economy in account ? we have developed suggestions on new packages that will facilitate handling and lower the total costs, The time of handling will in some cases abbreviate to just a few seconds with the new packages.

The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

Bakgrund: För att bedriva ett framgångsrikt miljöarbete kan företagen använda sig av olika hjälpmedel och verktyg. Ett exempel på ett sådant verktyg är ett miljöledningssystem. Det har diskuterats om miljöledningssystem i sig leder till miljömässig effektivitet. Det som anses vara av större vikt är på vilket sätt företag arbetar med miljöledningssystem.Syfte: Vårt syfte är att beskriva hur miljöarbete bedrivs och förklara om det bedrivs på ett sätt som gör att den miljömässiga effektiviteten i våra fallföretag kan förbättras. Ett delsyfte är också att undersöka om det finns någon skillnad i arbetssätt gällande miljöfrågor beroende på om verksamheten är offentlig eller privat.Metod:.

Syftet med detta examensarbete är att sammanställa maskinkostnader för etableringsmetoderna plöjningsfritt och konventionellt. Vi vill även titta på hur stor kapacitet som behövs på maskinparken för den tänkta gården på 600 ha åker, detta för att hinna etablera grödan inom ett rimligt tidsspektra. Anledningen till att vi valt ett företag på 600 ha är att det är den areal tröskan klarar av att avverka inom rimlig tid. Det medför att vi måste ta en del hänsyn till lägligheten och hur mycket av tiden som är så kallat ?tjänligt väder?.

This study will chart the changeover work, with a standpoint in the SMED-theory, at the company Peter Ernst AB in Värnamo. They are suppliers in plastic moulding industry and delivers to amongst other Saab in Trollhättan and Scania. The company are in a very competitive market, and they have to make manufacturing more efficient and rationalise their costs to be able to compete. A big problem, which the company has identified, is their long changeovers. It brings higher costs, a more stressful work climate and holds back the company from becoming more efficient.Field studies will be conducted on the changeover, which will be observed and filmed.

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.
