AI för Hive

Strategies for the board game Hive was implemented and evaluated in this project. The report covers the rules as well as the system that was implemented in order to build strategies. The strategies are evaluated based on how they perform against each other. Two search algorithms were implemented: Minmax and Alpha-beta pruning. Alpha-Beta with depth 4 had the best performance against other strategies as well as in individual tests..

Prediktion av beta för fonder

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Vitamin A och E i relation till hästutfodring :

The purpose of this study was to examine vitamin A and E in equine nutrition and especially in relation to forages. A literature review was conducted to examine factors that influence the level of vitamins present in forage, the vitamin A and E requirement of horses, and the absorption of vitamin A and E in horses. The influence of DM level on alpha-tocopherol and beta-carotene content in ensiled forage was investigated in a controlled ensiling study using baled silage and haylage. The results from the ensiling study were combined with data of vitamin A and E concentrations collected from literature. Calculations were done to theoretically establish how well the vitamin content in ensiled forage can cover the maintenance requirements of vitamin A and E in horses.

AI TILL BRÄDSPEL : En jämförelse mellan två olika sökalgoritmer vid implementation av AI tillbrädspelet Pentago.

I det här arbetet undersöks och jämförs två olika sökalgoritmer när de används för implementation av AI-spelare till brädspelet Pentago. De två algoritmerna som användes var alfa-betabeskärning och en nyare algoritm som kombinerar genetiska algoritmer och minimax, kallad genetisk minimax. Utvärderingen av resultaten visar att alfa-betabeskärning passar bättre vid implementation av en AI till Pentago än genetisk minimax. Alfa-betabeskärning med ytterligare optimeringar har potential att lämpa sig väldigt väl för implementation av spelare till Pentago. Ytterligare visar resultaten att genetisk minimax inte är en passande algoritm för AI till Pentago.

En jämförelsestudie av AP-fonderna och bankernas Sverigefonder 2003-2010

Background: In 1999 the Swedish pension system was reformed with an aim to create a stable and high return on pension assets. First, Second, Third and Fourth general pension funds, hereby referred to as AP1-AP4, had an important part in the reform. AP1-AP4, also called the buffer funds, was assigned to secure long-term, big parts of the pension capital. The funds objective is by law, to manage the fund's assets in a manner that provides maximum benefit for the state pension. The funds will also invest pension assets with an overall low level of risk while achieving a sustainable high return.Aim: The purpose of this study is to investigate whether the First-Fourth AP-Funds is meeting its objectives regarding risk and return according to Swedish law.

Betavärdet som mått på systematisk risk inom aktievärdering

The beta value is frequently described in theory and is a well known factor to quantify the systematic risk in shares through the CAPM model. Initially, this study describes the advantages and difficulties with the estimating process and the problematic nature of the assumptions and descisons included in published beta values.An alternative method, Bottom-up beta, to estimate the beta value that probably has not been tested under Swedish circumstances is applied. The problems and decisions that have to be made to derive an alternative value are studied in detail through six separate steps. I have chosen nine companies at the Stockholm Stock Exchange where this method is used. The result showed that the systematic risk were higher at five shares and lower at four, compared to the published values.Finally there is a discussion about the practise, usefulness and opinions concerning how to estimate and interpret the beta value to determine the expected return..

Betavärdet som riskestimat

As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.

Nyutveckling av hopfällbar kvistsåg

This Master Thesis has been carried out as a new product development project in collaborationwith G-Man Tools AB located in Edsbyn. The purpose of the project was to construct a newpruning saw there the blade is integrateble in the handle, thus a foldable pruning saw.The work has been performed on the occasion of G-Man Tools AB wanted to improve theirproduct range by creating a saw that complement their range of quality saws. They have a similarproduct today, but they do not manufacture this product by them selves and it is not directlytargeted against garden use, which is a disadvantage when it is one of their major markets.Even though almost the entire chain from the requirements of the users to drawings has beentaken into consideration, emphasizes has been put on generating ideas. However the first thingthat was carried out was to establish a productspecifikation from interviews with users and thecompany?s experience.

Downside Risk - En studie av riskkompensation på den svenska aktiemarknaden

This paper investigates the compensation for risk in the context of the Swedish stock market with a special focus on downside risk. Using daily market data collected from the A-list of the Stockholm Stock Exchange between the years 1983 and 2005 the purpose is to answer the question whether Swedish investors are compensated for holding stocks with high downside risk, measured as downside beta. Using panel data analysis it is shown, in accordance with most previous evidence in international research, firstly that stocks with high beta values on average experience higher returns than stocks with low beta values, and secondly that stocks with high downside beta values experience higher returns than stocks with high beta values in general. On the other hand, cross-sectional regression methodology using a bivariate regression approach shows that downside beta does not explain excess returns very well. Instead, regression analysis suggest that high upside beta does a much better job in explaining excess return over this time period compared to downside beta.

Beta : En studie om sambandet mellan systematisk risk och avkastning

Tester av CAPM och Beta av bland andra Eugene Fama och Kenneth French (1992) har visat att det inte existerar något samband mellan systematisk risk (beta) och avkastning för aktier på den amerikanska aktiemarknaden. Andra forskare hävdar att det kan finnas ett samband mellan beta och avkastning om den studerade tiden fokuserar på isolerade perioder med antingen positiva eller negativa marknader. Kritik har även riktats av bland annat Richard Roll för att olika index som approximation för aktiemarknaden vid beräkningen av beta kan generera helt skilda värden och således betyda att investerare kan ha olika förväntade avkastningar för samma aktie.I denna studie försöker författarna besvara frågan om det existerar ett signifikant samband mellan beta och avkastning på den svenska aktiemarknaden. I studien undersöks sambandet på en aggregerad nivå under den totala studieperioden mellan 2003-2011 och även under isolerade positiva samt negativa marknader under samma period. Författarna använder sig av två olika index som approximation för den svenska aktiemarknaden, OMX Stockholm PI och OMX Stockholm 30, vid beräkningen av beta. För att kunna undersöka sambandet delas aktierna in i portföljer där snittvärden på beta och avkastning beräknas och studeras sedan i regressionsberäkningar.Resultatet av studien visar att det existerar ett signifikant samband mellan risk, symboliserat av beta, och avkastning på den svenska aktiemarknaden vid positiva marknader under den studerade tidsperioden.
