Kapacitetsberäkningsmodell för materialhanteringsflödet på Ericsson i Kumla
Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.
Strategier vid generationsskifte : ekonomiska implikationer för olika intressenter
A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation. The grantor can choose between totally 8 different strategies to transfer the farm, of which purchase, gift and a mixed form of these are the most common. During 2007 almost 10 000 transfers of agricultural estates occurred in Sweden and the expectation for the coming years is that about 15 000 estates will be transferred each year. By the time a transfer is about to materialize there are usually several stakeholders that in one way or another is trying to influence the outcome of the transfer. The choice of transfer method affects the conditions and possibilities for compensating the siblings.
Safe retrieval of nutrients to improve food security
Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites.
The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.
Metod att mäta vakansgraden inom handeln - En fältstudie

Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?
The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
"Utan språket blir man både döv och stum" : En studie av avbrottsorsaker på grundläggande vuxenutbildning
The aim of this paper was to investigate how many students studying Swesdish as a foreign language, at secondary school level, in Tierps kommun, that have dropped out and their reasons for doing so. The reason for this is the report from Skolverket, stating that the rate of drop outs at this level is very high. To investigate this, a quantitative method was used. A questionnaire was sent out to all the students that dropped out 2005-2008. The result showed that the two main reasons for leaving their studies were that the individuals had found a job or thought the studies were too hard. The research also showed that the majority of the students had not been in contact with Career counseller prior to ending their studies. We came to the conclusion that there might be a need for developing the teaching and to work out routines for guidance at drop out situations.
Quality of Service i IP-nätverk
The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.
Varumärkets betydelse - en jämförelse mellan hur unga och äldre påverkas i köpprocessen
The thesis strives to answer the question whether there are any differences between how young customers, in comparison with older, are affected by brands when buying different products. The purpose is to get a clearer idea about the brands' importance in the future and in that way also to give guidance to companies about how to best market themselves and there products.To answer the question, an experiment was conducted with 480 respondents taking a survey where they had to rate a product after reading a short text about it. Some of the texts stated that a specific brand was behind the product while some said the product was produced by an unknown brand.The result of the study was that young people showed a greater propensity of rating products with a brand higher than products without brands, in comparison with the older respondents. This gives reason to believe that brands progressively will become an even more important tool for marketers and an unmatched asset for companies in the future..
Spolmaskangrepp är ett ökande problem hos värphöns
This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.
Strategiska påverkansmetoder i en livsmedelsbutik : en kvalitativ företagsundersökning på vad en butik gör för att påverka kundens inköpsbeteende
Corporate governance intensified due to the corporate scandals in the USA which led to a new law the so called Sarbanes-Oxley Act (SOX).In 2005 the "Svensk kod för bolagsstyrning" (The Code) was introduced. The main purpose of The Code is to strengthen the confidence in Swedish companies quoted on the Stockholm Stock Exchange. The Code focuses on the working process of boards. The rules set by The Code places higher demands on the board. Among many other duties the board has to establish long term operational goals and strategy.
Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster
The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
"Och så levde de lyckliga i alla sina dagar" : En analys av den borgerliga diskursen i den östgötska folksagan
Fairy tales are commonly considered to be both timeless and classless. Since the 17th century, when most of the tales we have access to today were first collected and published, the idea that fairy tales are part of an oral tradition, and therefore more or less uninfluenced by academic and literary trends, have been dominant amongst researchers, critics and readers. This idea needs to be revaluated. Even if the tales might have their roots in an oral tradition the history of the fairy tale ?is not primarily a history of oral transmission, but rather a history of print?, as Elizabeth Wanning Harries puts it (Wanning Harries, 2001:4).
Kringtjänster för fastighetsmäklare
The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market. To do so requires that the company chooses an appropriate range of peripheral services that are profitable. The problem is to choose the ?right? services to convey. The purpose of this paper is to describe the services that are in demand for transmission and how the agents can work to meet the demand of this new market.
Utvärdering av traktplanering på Holmen Skog
This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region.
For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn.
It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams.
The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient.
One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..
