A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

The Internet has developed into a marketplace for national and international companies. With relatively small means, a company can reach out to millions of people on a daily basis by placing itself on the Internet. With this report, we wish to suggest how e-businesses can change its strategy to adapt to the new market. Focus is on the Swedish Internet market where Swedes, resident in Sweden, trades with Swedish e-companies active within the Swedish borders. To be able to make suggestions, we will first paint a picture of the Swedish e-commerce market from statistics collected from public sources.

Due to the highly competitive and busy marketplace of today, companies are forced to take unforeseen measures in defending and developing their brands. Key elements like opinion leadership and lifestyle marketing are commonplace and aim to deliver values that are more difficult to define compared to quality, price, looks and usability. This paper aims to develop what should be considered most fundamental to all commercial branding. By investigating the ideologies that are the core of many successful companies, we hope to clarify the importance of communicating these ideologies. The topic is examined by method of quantitative analysis and the main purpose is to determine; what do the companies think of their ideologies, and how do their consumers recieve them? A secondary purpose is also to investigate whether different kinds of consumers recieve the ideologies in different ways..

AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated.  It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

Hur bör resebranschens förhållningssätt gentemot All-inclusiveturism gestaltas ur ett CSR-perspektiv?Syfte: Huvudsyftet är att beskriva hur resebranschen kan justera sitt förhållningssätt gentemot All-inclusiveturism för att bättre gagna en långsiktig hållbar samhällsutveckling i de länder där verksamhet bedrivs. Delsyftet bottnar i att undersöka och analysera hur den rådande All-inclusiveturismen påverkar samhället ur ett långsiktigt hållbart samhällsperspektiv.Metod: Studien är av kvalitativ karaktär och baseras på sekundärdata i form artiklar, rapporter och böcker för ämnet relevant litteratur samt primärdata i form av personliga intervjuer med profiler som förespråkar hållbar turism. En fallstudie av den svenska resebranschens förhållningssätt till en långsiktig hållbar samhällsutveckling genomfördes med en deduktiv ansats. Vidare tolkades referensramen och empirins insamlade material för att skapa en analys och slutsats.Slutsats: Givet att nedanstående förslag implementeras kan resebranschen justera sitt förhållningssätt gentemot All-inclusiveturism för att bättre gagna en långsiktig hållbar samhällsutveckling i de länder där verksamhet bedrivs.1.

The competition policy in the EU should guarantee that the competition is not distorted in the way that would prevent or create difficulties for the free mobility of goods and services between Member states. It is prohibited for companies to abuse their dominant position according to Article 82, if it affects trade. The essence of Article 82 is control of market power. The perfect competition results when supply and demand appoint the price and quantity of a product. Firms are encouraged to compete then it results in efficiency, quality products and lower prices.

The price trend on rapeseed the latest years has led to an increasing interest to grow the crop among many farmers in Sweden. The price trend has resulted in more than a doubling of the oilseed area since the early 2000s. For many farmers it is an advantage to increase cultivation of rapeseed because of the high proportion of cereals in the crop rotation on many farms, but it is not just benefits. The risk of the fields being infected by clubroot increases within frequent rapeseed cultivation and it often leads to subtantial economic losses. Clubroot is caused by Plasmodiophora brassicae that is a soilborne pathogen in genus Protozoa and its resting spores can be found in the soil for up to 18 years.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

Rental rates and land prices have gone through substantial changes the last two decades. The prices have both gone up and down since 1990 but from 1995 to 2008 land prices increased with 272 percent and rental rates with 61 percent. What factors that have the largest impact on rental rates and land prices are hard to determine but factors that may affect the price are the desire to live in the countryside and the expected profitability in agriculture. Prices of products and inputs are factors that affect the profitability in agriculture, but the profitability is also affected by agricultural policies. The economic for Swedish agriculture have changed several times over the last 20 years as a result of changing agricultural policies.The agricultural policies largely affect farmers behavior and decisions.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

The essay initially intends to find adequate models to describe and forecast monthly data for the Swedish Consumer Price Index sub group Clothes and Shoes 1986-2005. The time series observations during 2006 are considered ?out of sample period? which is used to evaluate the forecasts. The purpose is to perform time series decomposition and to investigate and analyzethe seasonal pattern. The Box-Jenkins approach is used to find adequate ARIMA models.

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
