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..

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Farmed mink often perform stereotypic behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages. In the present study the behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Abstract:Title: The popular blog ? on updating and its effects on vistor statisticsNumber of pages: 35Author: Wilhelm von SydowTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Autumn 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: To examine to which, if any, extent the update frequency of blogs affects their visitor statistics.Material/Method: Quantitative method, Swedish blogs, visitor statistics and updating frequency.Main results: No results could prove the causal effects of the relation between visitor statistics and updating frequency. A noticeable connection between the two variables could, however, be identified.Keywords: Blog, update frequency, visitor statistics, quantitative, Habermas, public sphere, Else Nygren, intranet, Matt Haig, business websites.

This thesis deals with the field of warehouse management, focusing on frequency control of stock. The purpose of the thesis is to reduce the warehouse staff mileage by placing an article based on its number of picks, i.e. how frequently it gets picked. In order to achieve relevant results the following four questions have been answered in the thesis: How should the articles be placed with regard to the picking frequency?Which factors, if any, needs to be addressed beyond the picking frequency when articles are placed based on frequency?Can the present picking system be improved?Is frequency placement with regard to the picking frequency profitable to implement for the company?The thesis is based on literature studies and on the data that has been collected from the company?s business system.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.
