The purpose of the thesis is to demonstrate how high frequency trading affects the stock market. The growing high frequency trading is affecting the game plan on the financial markets and concerns have grown about the high frequency users intentions with their business. It is difficult to receive an overall picture of the subject because the lack of previous research and even the research that exist do not show the entire picture. The thesis contributes to the research through a comprehensive picture of the present debate as well as the previous research through a literature study. Our results showed that high frequency trading provides liquidity to the market, there is a statistical connection between high frequency trading and volatility, no price manipulation is being used and there is a need for a supervision of the high frequency trading..

It is important to understand the process of appraisal of a business in order to establish its value. The purpose of our thesis is to establish which methods and models are used when evaluating a business and investigate the factors that may affect the value and price tag of a business. We have used a qualitative approach by conducting both indepth interviews and a survey as well as reading literature within the field. The main conslusion in our findings is that the common practice of discounted cash flow is widely used when bestowing a monetary value for a business, and in order to raise the value a well established customer relationship was the single most important factor. As far as lowering the value, the answers were of such a wide spread that a single factor could not be attributed.

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production. Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy. The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.

Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.

In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..

The theologian Sarah Coakley has developed a theological method, which she calls théologie totale.This essay examines the methodological criteria for this method. To understand how its anthropology, epistemology and theology are shaped, the criteria are analyzed within a theoretical framework, in which mainly David F. Ford's theological typology and Stephen Bevans models of contextual theology play parts. The material consists of Coakleys texts, essentially the first part of Coakley?s projected systematic theological work.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Humor is as interesting as it is hard to define. It has travelled a long way since Hippokratestheory about body fluids and how someone, if lacking one of these, were called a humorist andwere laughed at.In this thesis we developed a new method for categorizing types of humor in Swedish comedyseries on TV. We chose six different shows (Grotesco, KvarteretSkatan, Morgonsoffan, Fredaghelaveckan, Parlamentet and Hjälp!) from the two most popular TV-channels in Sweden(SVT1 & TV4).We based or method on previous researchers? work and came to find some categories that wererepresented in most of the previous work. Our own method came to contain seven categorieswhich we believe is enough to obtain all kinds of humor in Swedish comedy series on TV.In our study we saw that most of the humor fell under the category that we called unnormalityhumor,a category which contained incongruity which many researchers believe is afundamental part of humor.Our opinion is that the unnormality-category became too wide in our study and that we perhapsshould have divided it into two or possibly three categories to see a more distinctive result.Nonetheless, our result offers an interesting starting point for future comparative studiesfocusing on similar subjects..
