During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

Vi har genomfört en kvalitativ studie på en lagerverksamhet som till stor del använder sig av bemanningsföretag för att möta marknadens behov av olika toppar och dalar. Företaget som vi har gjort vår studie på vågar gå mot strömmen och satsa på sin verksamhet, då de har genomfört en stor omorganisation, jämfört med många andra företag på dagens marknad.Vi har genomfört intervjuer på sex personer som är anställda av företaget och som jobbar som lageranställda, dessutom har vi genomfört två intervjuer med personer som jobbar högre upp i hierarkin och som är anställda via bemanningsföretag. Till en början hade vi ett deduktivt förhållningssätt baserad på Lean Production. Men då empirin gav oss intressanta infallsviklar lät vi denna styra vår studie vilket innebar att vi fick andra teoretiska utgångspunkter och dessutom en blandning av deduktiv och induktivt förhållningssätt. Bland annat valde vi Foucaults teori kring övervakning som huvudfokus i vår studie då det var kring detta ämne vi fick fram intressant empiri.

My main purpose with this paper of John Steinbecks Of mice and men is to both analyze the long-lived structures and the unique individual destinies of the novel. I employ the method of the historical Annales-movement and use three divided levels in my analysis to try to capture these high structures and low moments of humanity in Structure, Konjuncture and the Individuality. The first level, Structure, is used to see how long-lived almost invisible geographic structures set the human act of condition. The second level, Konjuncture, is easier to grasp in understanding of time and embraces for example economic structures as the industrialism. The last level of Individuality is the fastest in time and easiest to understand but in the long run also the least important.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

Titel: Value stream mapping in practice ? A case study at Light MyFireAuthors: David Rydman and Tomas ÖnnemarMentor: Veronica Ülgen SvenssonExaminer: Åsa GustafssonBackground: Companies push their prices in today's markets to be competitive, which means that companies need to find ways to reduce costs while maintaining profits. (Cudney, 2009) According to Bergman and Klefsjö 2007, the basic rule of quality improvement says "there is always a way to achieve higher quality at a lower cost". One way is to improve a company's processes to get a more efficient flow and improvements that may cut costs. (Bergman & Klefsjö, 2007) Why it's important to look at the processes are that they often contain waste that can be eliminated.

Detta examensarbete har genomförts på Aven Rabbalshede AB i syfte att kartlägga företagets dåvarande situation i dess interna logistikflöde, för att sedan lägga fram förbättringsförslag som kan implementeras för att förbättra detta flöde. Målet var att reducera trucktrafiken i fabriken med minst tio procent.Aven Rabbalshede AB är ett tillverkningsföretag av lastpallar, träemballage, transportstöd och lådor. Företaget är en del av Avenkoncernen som är en av Skandinaviens ledande tillverkare av lastpallar och träemballage. Aven Rabbalshede AB är den största enheten inom koncernen med cirka 55 anställda och en produktion på cirka 1,3 miljoner lastpallar per år. Företaget hade en bristande struktur och systematik över truckflödet och materialhanteringen vilket har inneburit stora och många mellanlager samt andra svårigheter.Examensarbetet innebar att först och främst kartlägga vad respektive truck gjorde under en arbetsdag för att kunna analysera hur dåvarande situation såg ut.

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Abstract A phenomenon that has been noticed more and more in media and the public space in recent years is what is called guerrilla gardening. It means the illicit cultivation of someone else?s land. This report's intention is to analyze what impact guerrilla gardening could have on today's urban space in terms of stable changes in norms and physical design. I have also focused on guerrilla gardener?s choice to carry out these actions illegally, without asking for permission, and what impact that could have on the issue of appropriating public space.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

The existence for companies today consists of constant challenges with customers that want more individual products with high quality as quickly as possible. For a company to be able to have a short delivery time, it must also have a short production time. This makes streamlining and improvement of processes a big part of a company?s workThis thesis has been carried out together with the company Lasermax Roll Systems AB, a world-leading manufacturer of feeding, finishing and monitoring systems for high-speed digital printers. They manufacture their products according to the assembling for costumer order principle.The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB.

A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.
