Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Outnyttjad kreativitet och kompetens inom produktion : - Ett arbete som fokuserar på att fånga upp och ta tillvara på medarbetares kreativitet och kompetens

AbstractResource efficient manufacturing is a term that has been increasingly applied within manufacturing, where one of the key points is to reduce waste of such forms that do not add value for the end customer. By the Lean principles, there are seven plus one types of waste, in which the definition of the eighth point varies among sources. In this study, the eighth type of waste has been interpreted as the untapped creativity and competence among employees that has not been put to use. From this, our question was incubated; How can you make the most of the employees? untapped creativity and potential within manufacturing? The case study will be developed with empirical data obtained from Dometic Group by conducting interviews.From the gathered literature, it was concluded that the communication between employees contributed to an increased understanding of one another as well as it allowed for improvement in work.

Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

Förekommer nedskrivningar av goodwill på Stockholmsbörsen i större utsträckning vid sämre redovisade resultat?

Background: Goodwill has always been frequently discussed and a lot of scientific research has been done regarding factors that affect companies? impairment of goodwill. Previous research has concluded that companies reporting low results are more prone to do impairments of goodwill than companies reporting better results which possibly can be seen as a form of earnings management.Purpose: The purpose of this essay is to examine if goodwill impairments occur to a greater extent among Swedish listed companies when the companies are reporting lower earnings. A subsidiary purpose is to see if there has been an improvement since 2008 regarding the size of reported goodwill in comparison to equity in the years 2009-2011. And to analyze the development of the companies goodwill impairments in relation to reported goodwill.Methodology: Three quantitative studies have been performed for the years 2009-2011 where all the listed companies on NASDAQ OMX Stockholm have been included.

Effektivisering av ventilationsprojekt : Bravida Filial Uppsala

In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.

LAURA: Kognitiv beteendeterapi för kvinnor med psykisk ohälsa till följd av en traumatisk förlossning : En randomiserad kontrollerad studie av internetadministrerad vägledd självhjälpsbehandling

The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Implementering av Lean genom TAK och SMED

This graduation work is a result of implementing Lean Production using OEE and SMED at Enics Sweden AB in Malmö. Enics doesn?t have an established improvement concept and therefore should this work serve as an introduction to possibly start with Lean Production. A result in this report is that an OEE value has been identified within a common order at Enics. Other results are that an implementation of a Lean-board has been implemented and furthermore, within SMED, a flag that indicates changeover..
