The thesis is composed of three essays on auction theory. The focus is mainly on the English auction, which is probably the format most commonly used. In the English auction, a bidder can see his opponents’ activity as the price is gradually raised starting from a very low price. When only one bidder is left, such bidder is declared the winner and pays the price at which the last but one bidder...

futures contract is one of the most important derivatives that is used in financial markets in all over the world to buy or sell an asset or commodity in the future. pricing of this tool depends on expected price of asset or commodity at the maturity date. according to this, theoretical futures pricing models try to find this expected price in order to use in the futures contract. so in this ar...

we derive closed formulas for the prices of european options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by s. kou in 2002. this author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...

Many years ago, as a cadet hoping some day to be an officer, I was pouring over ‘Principles of War,’ listed in the old Field Service Regulations, when the Sergeant-Major came up to me. He surveyed me with kindly amusement. ‘Don’t bother your head about all them things, me lad,’ he said. ‘There’s only one principle of war and that’s this. Hit the other fellow, as quick as you can, and as hard as...

R oanoke, Virginia is a city with a population of approximately 99,000 and a police force of 248 sworn officers at full staffing. In 1991, the Roanoke Police Department began its community policing effort with a small specialized unit, COPE (Community Oriented Policing Effort). This program began with eight officers and one sergeant and was partially funded by the Roanoke Redevelopment and Hous...

The purpose of this study is to compare the gelling behavior of two molecules: a chiral compound and its achiral counterpart. The chiral partner is characterized by a rigid, chiral pyrrolidine nucleus, while the achiral one contains a flexible diethanolamine moiety. The chiral compound is an already known good organogelator, but also the achiral compound shows remarkable gelling properties. Ver...

Let M be a manifold equipped (locally) with a pair of complementary foliations. In Catuogno, da Silva and Ruffino [4], it is shown that, up to a stopping time τ , a stochastic flow of local diffeomorphisms φt in M can be decomposed in diffeomorphisms that preserves this foliations. In this article we present techniques which allow us to extend the time of this decomposition. For this extension,...
