This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

The state of our society is frequently changing. Due to various factors, the pressure of creating a changeable city is high and necessary to adequately supply the needs for its inhabitants. But making these changes and adapt to the fast shifting state of the city is not always physical possible. Young adults and students is a group that often seeks to move to intensely growing city regions. The reason for this is a more promising job market and more attractive educations, but coincidentally the shortage of housing is extremely high in these areas.

This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e.

Husqvarna AB operates two warehouses located in the area of Jönköping. The most important task is to manage the large volume fluctuations during the peak season. DHL Exel Supply Chain (DESC) run the warehouses and the domestic transportations is outsourced to DHL Express. A number of forwarder agents are responsible for distributing the export gods. In the present situation a bottleneck occurs at the warehouse loading section, and the consequence is fulfill the time of delivery for all customer orders.

Idén till uppsatsen uppstod efter att ha läst Jan Carlsson et al: s avhandling och artiklar inom ämnet logistiskt förändringsarbete. Flera forskare problematiserar avsaknaden av teorier inom ämnesområdet samt lyfter fram bristerna i den existerande logistikforskningen som enligt forskarna inte lyckas fånga logistikförändringarnas komplexa natur.Syftet med uppsatsen var att med utgångspunkt från befintlig forskning inom området för logistiskt förändringsarbete och supply chain management, utvärdera och analysera logistiskt förändringsarbete i två företag. Utifrån befintliga teorier sammanställde vi en övergripande syntes med syfte att visa vår tolkning av hur logistiskt förändringsarbete skulle kunna hanteras. Ur denna syntes extraherade vi variabler som ansågs vara av betydelse för den empiriska studien. Undersökningen genomfördes som en fallstudie i två företag med ostrukturerade intervjuer med personer inblandade i förändringsarbetet.Resultaten vi kom fram till var att medvetenheten finns om att ta hänsyn till flera dimensioner i förändringsarbetet men det förarbete företagens utför underbygger inte alltid denna vetskap..

Share repurchases in Sweden has since legalization in 2000 gained momentum. Similar to other corporate events, there are studies that examine whether this affects the share price performance. With studies in the U.S. that measured excess returns of approximately 3,5 percent on the announcement day; Swedish buybacks, holding a tighter regulation is of interest to study. The Stockholm Stock Exchange regulation regarding reporting is also similar to the Stock Exchange in Hong Kong.

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

The pig industry suffers economical loss due to stillbirths, piglet mortality and low birth weight. This is due to breeding programs that have resulted in larger litters. It has been suggested that these problems are due to the metabolic state of the sow during gestation and the fact that she might not be able to supply her foetuses with enough nutrients for survival and a high and even birth weight. A lot of research has been done to investigate whether body weight and back fat thickness of the sow has any impact on her reproductive traits and if there are any special feed components that improve reproduction. Fibers and unsaturated fatty acids have a positive impact on reproductive traits as long as the sow is fed a sufficient amount of energy and protein during gestation and lactation.

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Fantasy literature has a rather strong position in countries with an English-speaking population but not in Sweden. The supply of fantasy in Sweden is much smaller than that in for example United Kingdom. Does this affect the Swedish readers of this genre? If it does, how does it affect them? The aim of this thesis is to find out how a few fantasy-reading students at the Swedish School of Library and Information Science get hold of the fiction they want to read and who and/or what influence their decision of which book to read. In order to avoid confusion we are also going to try to find out how they define fantasy since it varies from person to person what is included in the genre.

Läkemedelsbranschen är idag hårt konkurrensutsatt vilket skapar incitament till förändring av de interna processerna av vilka inköp utgör en. Läkemedelsbranschen har av tradition ansetts ha en eftersatt inköpsverksamhet för att vara en så mogen bransch. Vår undersökning gick ut på att jämföra en Best Practice modell för inköp med inköpsverksamheten i läkemedelsbranschen. För läkemedelsbranschen finns helt klart utvecklingsområden och utmaningar i förhållande till den gängse inköpsteorin och Best Practice modellerna. Vid en jämförelse med Best Practice modell för inköp och vårt fall identifierade vi ett antal avvikelser beroende på rationella, politiska och ekonomiska orsaker.

The Earth and everything else in the universe was created in the Big Bang around 14 billion years ago. A point with tremendous density and mass began to expand and more and more atoms began to form. From the first and lightest like hydrogen and helium to heavier atoms such as iron and eventually gold. The formation of the Earth occurred about 4.6 billion years ago and so the first gold atoms were concentrated only here. It is however believed that much later in Earth's history an extra supply of gold occurred thanks to massive meteorite bombardments.

Fresh water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.

Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.
