Download or read book Nouveaux estimateurs pour l optimisation des syst mes automatis s de n gociation d options written by Gabriel Laprise and published by . This book was released on 2018 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les options sont des produits financiers modernes permettant une approche stratégique à l'investissement. Les possibilités qui s'offrent à l'investisseur avec l'utilisation de ces produits sont vastes. Certains investisseurs les utilisent de manière subjective pour prendre position dans le marché et d'autres développent des stratégies plus systématiques afin d'enrichir leur portefeuille. L'objectif de ce mémoire est d'améliorer le rendement composé annuellement, ajusté au risque, des systèmes automatisés de négociation d'options comparativement aux méthodes usuelles. Deux contributions principales ont été faites pour y arriver. Premièrement, nous avons développé un estimateur de la moyenne de gain, conditionnelle à un ensemble d'information, d'une stratégie quelconque d'options. Deuxièmement, nous avons formulé un nouveau problème d'optimisation à variables discrètes pour la sélection des paramètres des stratégies. De plus, nous avons utilisé un algorithme de résolution avec des propriétés de convergence. Une contribution secondaire a été le développement d'un algorithme pour la liquidation des stratégies exploitant un ensemble d'information. Les performances de notre système ont été simulées en utilisant des données historiques et un ensemble d'information standard. Les résultats de ces simulations montrent que notre système mène à des rendements supérieurs aux systèmes usuels avec un niveau de risque comparable, dans certains cas. Les meilleurs résultats sont obtenus lorsque l'on utilise seulement des options sur indice. Les simulations utilisant des options sur action et indice mènent à des rendements moins élevés. De plus, notre algorithme de liquidation permet de réduire le risque du système en gardant un rendement relativement stable. Le mémoire se déroulera comme suit. Nous allons débuter en introduisant tous les concepts importants reliés à la négociation d'options et aux marchés financiers. Ensuite, nous ferons une revue de littérature exhaustive des systèmes de négociation automatiques d'options existants. Nous discuterons des lacunes de ces systèmes ainsi que des liens avec le nôtre. Puis, nous effectuerons le développement théorique des éléments de notre système de négociation. Finalement, nous expliquerons comment nous avons mis en place et simulé notre système et nous présenterons les résultats.

Download or read book The Global Forest Products Model written by Joseph Buongiorno and published by Academic Press. This book was released on 2003-02-24 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Global Forest Products Model (GFPM) book provides a complete introduction to this widely applied computer model. The GFPM is a dynamic economic equilibrium model that is used to predict production, consumption, trade, and prices of 14 major forest products in 180 interacting countries. The book thoroughly documents the methods, data, and computer software of the model, and demonstrates the model's usefulness in addressing international economic and environmental issues. The Global Forest Products Model is written by an international multi-disciplinary team and is ideal for graduate students and professionals in forestry, natural resource economics, and related fields. It explains trends in world forest industries in the simplest terms by explaining the economic theory underlying the model. It describes six applications of the GFPM, three of which were commissioned by the Food Agriculture of the United Nations, the USDA Forest Service, and New Zealand Research. The authors show how to apply the model to real issues such as the effects of the Asian economic crisis on the forest sector, the effects of eliminating tariffs on international trade and production, and the international effects of national environmental policies. They provide complete explanations on how to use the GFPM software, prepare the data, make the forecasts, and summarize the results with tables and graphs. Comprehensive, and rigorous description of the world forestry sector Written by an international multi-disciplinary team Thorough description of data and methods In-depth applications to modern economic and policy issues Detailed documentation of the computer software Suitable for students, researchers, and decision makers

Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Available in PDF, EPUB and Kindle. Book excerpt: During the last two decades actuarial research has developed in a more applied direction. Although the original risk models generally served as convenient and sometimes tractable mathematical examples of general probabilistic and/or statistical theories, nowadays models and techniques are encountered that can be considered to be typically actuarial. Examples include ordering of risks by dangerousness, credibility theory and techniques based on IBNR models. Not only does this book present the underlying mathematics of these subjects, but it also deals with the practical application of the techniques. In order to provide results based on real insurance portfolios, use is made of three software packages, namely SLIC performing stop-loss insurance calculations for individual and collective risk models, CRAC dealing with actuarial applications of credibility theory, and LORE giving IBNR-based estimates for loss reserves. Worked-out examples illustrate the theoretical results. This book is intended for use in preparing university actuarial exams, and contains many exercises with varying levels of complexity. It is valuable as a textbook for students in actuarial sciences during their last year of study. Due to the emphasis on applications and because of the worked-out examples on real portfolio data, it is also useful for practising actuaries to guide them in interpreting their own results.
