  • It was in late 1995 to early 1996 (shortly after the birth of his first daughter Claire) that the author first began to read the currently available finance books in order to write C/Cþþ financial software. However, apart fromthe book Options Futures and Other Derivatives by John Hull, he found very little information of practical help and had to trawl through the original journal articles in the Bodleian library for more information. Even then much information on how to implement and test various models was not included.

  • Due to the enormous progress in computer technology and numerical methods that have been achieved in recent years, the use of numerical simulation methods in industry gains more and more importance. In particular, this applies to all engineering disciplines. Numerical computations in many cases offer a cost effective and, therefore, very attractive possibility for the investigation and optimization of products and processes.

  • We examine the problem of choosing word order for a set of dependency trees so as to minimize total dependency length. We present an algorithm for computing the optimal layout of a single tree as well as a numerical method for optimizing a grammar of orderings over a set of dependency types. A grammar generated by minimizing dependency length in unordered trees from the Penn Treebank is found to agree surprisingly well with English word order, suggesting that dependency length minimization has influenced the evolution of English. ...

  • A better understanding of the influence of tobacco smoke on the host response to periodontal infection has been the major concern in numerous studies whereas, limited research has been published aiming to identify the influence of tobacco smoke on the dental biofilm. Tobacco smoke has been shown to cause shifts in the microbial species that comprise dental plaque (Haffajee & Socransky 2001, Kamma et al. 1999, Shiloah et al. 2000, Umeda et al. 1998, van Winkelhoff et al. 2001, Zambon et al. 1996). In a recent study by our group (Buduneli et al.

  • n view of the growing importance of product liability and the demand for fulfillment of extreme specifications for new products, this book provides the basic tools for establishing model equations in structural mechanics. Additionally, it illustrates the transition and interrelation between structural mechanics and structural optimization. Nowadays, this new direction is extremely important for more efficiency in the design process. The book is divided into four parts covering the fundamentals of elasticity, plane and curved load-bearing structures and structural optimization.

  • This book presents and develops major numerical methods currently used for solving problems arising in quantitative finance. Our presentation splits into two parts. Part I is methodological, and offers a comprehensive toolkit on numerical methods and algorithms. This includes Monte Carlo simulation, numerical schemes for partial differential equations, stochastic optimization in discrete time, copula functions, transform-based methods and quadrature techniques. Part II is practical, and features a number of self-contained cases.

  • This book, based on intensive research I have conducted since the late 1970s, is my attempt to cover in one monograph the modern theory of surface generation with a focus on kinematic geometry of surfacemachining on amultiaxis numerical control (NC) machine. Although the orientation of this book is toward computer-aided design (CAD) and computer-aidedmanufacturing (CAM), it is also useful for solving problems that relate to the generation of surfaces on machine tools of conventional design (for example, gear generators, and so forth)....

  • Evolutionary computation has been widely used in computer science for decades. Even though it started as far back as the 1960s with simulated evolution, the subject is still evolving. During this time, new metaheuristic optimization approaches, like evolutionary algorithms, genetic algorithms, swarm intelligence, etc., were being developed and new fields of usage in artificial intelligence, machine learning, combinatorial and numerical optimization, etc., were being explored.

  • Numerous U.S. REITs and other institutions have invested in real property connected to maquiladoras, retail development and tourism. This trend should persist because Mexico is ripe for continued investment. With respect to retail development, for example, there are fewer than 1,000 malls and shopping centers in Mexico, which has a population of approximately 110 million people. In comparison, there are more than 102,000 malls and shopping centers in the U.S., which has a population of approximately 306 million people.

  • Given the spatial relationships extracted as described above, our goal is to integrate this information into an optimization framework with a properly defined cost function quantifying the quality of the furniture arrangement. Given an arbitrary room layout populated by furniture objects, the synthesized arrangement should be useful for virtual environment modeling in games and movies, interior design software, and other applications. The search space of our problem is highly complex as objects are interdependent in the optimization process.

  • The rest of the paper is organized as follows. Section 2 evaluates the situation of German banks in terms of capitalization. In section 3, bad bank solutions of the past are studied and prerequisites for success are examined. Section 4 develops a classification scheme for existing and planned bad bank solutions. We develop in Section 5 the efficient design for a public bad bank. Section 6 evaluates the German Government’s bad bank proposal. Section 7 concludes. Two simple numeric examples illustrate the working of both bad bank plans in the Appendices. ...

  • Medical imaging has been transformed over the past 30 years by the advent of computerized tomography (CT), magnetic resonance imaging (MRI), and various advances in x-ray and ultrasonic techniques. An enabling force behind this progress has been the (so far) exponentially increasing power of computers, which has made it practical to explore fundamentally new approaches.

  • Numerous reports, including some from the National Research Council, have examined the relationship of diet to cancer. It is generally accepted that diet is a contributing factor to the onset or progression of some types of cancer and that a prudent selection of foods, including fruits and vegetables, and avoidance or decreased consumption of other foods might influence the risk to an individual of contracting cancer.

  • This proposition can be illustrated with an analysis of discrimination in South Africa, where blacks are four to five times as numerous as whites. Discrimination against blacks has also significantly hurt whites, although some white groups have benefitted (see Becker [1971, pages 30 - 31], and Hutt [1964]). Its sizable cost to whites suggests why apartheid and other blatant forms of Afrikaaner discrimination eventually broke down.
