There is little doubt that the use of digital images in learning, teaching and research projects is growing. Typical uses include: supporting lectures and other presentations; creating Web-based instruction and creating digital image archives. Another aspect of digital images is that they can be delivered on a variety of supports: PowerPoint, Web, image database, CD-ROM, and print.
It is therefore important to be familiar with image digitisation processes in order to obtain images that will be ‘fit for purpose’. This document shows you how to apply image enhancement techniques using Adobe Photoshop CS2.
The RealCredit advanced payment system is a computer program that has the ability to perform secure credit and debit card transactions. The program communicates over the Internet to a central server operated by RealCredit, which in turn communicates with the acquiring banks.
This document gives a roadmap and specifics for implementing the RealCredit payment system into a Windows based application, from a web application through to a billing platform.
In this article, we analyze the impact of risk aversion on the valuation of defaultable bonds, and a simple multi-name credit derivative. Our approach is to work within intensity-based models, as initiated by, among others, Artzner and Delbaen, Madan and Unal, Lando and Jarrow and Turnbull. However, rather than pricing using no arbitrage arguments, we study the utility-indifference valuation mechanism, which entails analysis of portfolio optimization problems under default risk.
A major limitation of many traditional approaches is the inability to capture and explain high premiums observed in credit derivatives markets for unlikely events, for example the spreads quoted for senior tranches of CDOs written on investment grade firms. The approach explored here, and in our related work [28], aims to explain such phenomena as a consequence of tranche holders’ risk aversion, and to quantify this through the mechanism of utility indifference valuation.
