This thesis explores how transaction costs affect the optimality of hedging when using Black-Scholes option pricing model. Further, a number of models developed to improve the hedging results of Black-Scholes, when accounting for transaction costs, are analysed and compared. To numerically evaluate these strategies, extensive Monte-Carlo simulations are generated and the results of the strategies

This is a qualitative study of the children's home Onesimus' Brothers. In 1992 pastor Dugulescu decided to start a program to meet the streetchildrens needs. The purpose of this paper was to explore how the children's orphanage is organised and what the purpose and the methods of the work are. The question asked were: * How has the institutional care on the orphanage developed and chan

There is today an ongoing debate about Fair Trade and its consequences. The way to reach an understanding about the producers lives is important if the future will be liberated from the uneven access to the market. Today the free market is dominated by a few multinational companies and for poor producers there is no chance to compete at the same level. If industrial countries continue to exploit d

The urbanization term is widely used in contexts, when discussing urban emergence. However, the term linked to processes multidimensional which requires a wide perspective on what forms the basis for changes in the landscape. It is not only the origin that is essential in urban development matters, but also how the multi-dimensional processes vary with different factors in the landscape over time,

The effect that organic solvents have on the environment and the intrinsic risk that come with using them should be limited. By replacing organic solvents with less harmful solvents, such as water, and with more effective catalysts can risks intrinsic to organic solvents be minimized or eliminated. The focus of this project is testing if Michael addition using transition metal salt catalysts with

This paper focuses on pricing of basket Credit Default Swaps. The credit market instruments such as CDSs and CDOs are introduced. The concepts of trading these derivatives in basket CDSs divided into tranches is also of big importance. Dierent pricing models are presented and compared. Those are Semi-Analytic Valuation model with a Copula approach used together with the methods compound and base c

This paper presents an investigation on the compressive behavior of plain concrete columns confined with steel-reinforced grout (SRG) composites. The test parameters include size and crosssectional shape (square or circular) of the columns, and number of layers (one or two) and density (low or medium density) of the steel fiber sheet. Out of 46 specimens herein presented, 33 were confined with SRG

The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the Blum-Kalai-Wasserman (BKW) algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For the Regev parameters $q=n^2$

The European Spallation Source (ESS), presently under construction in Lund, Sweden, is designed to be the world's brightest neutron source. When it will be in operation, ESS will deliver an instantaneous neutron flux on detectors that will be without precedent. A down side of the high brightness will be the increase of background, especially from gamma-rays and fast-neutrons.Considering that scatt

The latest version of the Swiss standard for building acoustics (SIA181) introduced a new measurement method, based on a balanced- Arm hammer, for evaluating the decoupling performance of service equipment. This method was developed for reproducing in a standard manner the manipulation of service equipment in bathrooms and kitchens. In this study, we are investigating the relevance of such method

Fear of large carnivores such as brown bears may restrict people’s outdoor activities regardless of experts’ estimated risk of attack. This research study empirically examined three exposure interventions in the form of guided walks intended to give people living in brown bear areas tools for coping with their fear. All interventions significantly reduced fear, decreased people’s perceived vulnera

An in-house-made alignment system for deep X-ray lithography is presented that features low costs, low weight and little demand in space. Synchrotron radiation illuminates alignment marks on mask and substrate. The radiation transmitted through these alignment marks is detected by X-ray-sensitive diodes. The mask is fixed to the vacuum chamber, whereas the substrate is mounted on a six-axis kinema
