Numerical Methods for Controlled Stochastic Delay Systems
The Markov chain approximation methods are widely used for the numerical solution of nonlinear stochastic control problems in continuous time. This book extends the methods to stochastic systems with delays. Because such problems are infinite-dimensional, many new issues arise in getting good numerical approximations and in the convergence proofs. Useful forms of numerical algorithms and system approximations are developed in this work, and the convergence proofs are given. All of the usual cost functions are treated as well as singular and impulsive controls. A major concern is on representations and approximations that use minimal memory.
Nonlinear Optimization with Financial Applications
The book introduces the key ideas behind practical nonlinear optimization. Computational finance—an increasingly popular area of mathematics degree programmes—is combined here with the study of an important class of numerical techniques. The essentials of most currently popular algorithms are described and their performance is demonstrated on a range of optimization problems arising in financial mathematics. Theoretical convergence properties of methods are stated and formal proofs are provided in enough cases to be instructive rather than overwhelming. Practical behaviour of methods is illustrated by computational examples and discussions of efficiency, accuracy and computational costs. Supporting software for the examples and exercises is available
New Political Economy of Exchange Rate Policies and the Enlargement of the Eurozone
This work examines the political economy of exchange-rate policies in the context of the eastward enlargement of the eurozone. The analysis shows that prospective members of the EMU are likely to pass on some of the incurred Maastricht costs of convergence to the current EMU-members. The transmission mechanism is an altered exchange-rate policy that is carried out utilizing a "threaten-thy-neighbour"-strategy. The nature of the arising conflict between current and prospective EMU-members originates from both parties' admitted inclination to complete the enlargement process, complicated by their disinclination to bear the costs. The ensuing moral-hazard behaviour of the CEECs proves to be one of brinkmanship.
Natural Language Processing and Information Systems ; Vol. 3513 ; 10th International Conference on Applications of Natural Language to Information Systems, NLDB 2005, Alicante, Spain, June 15-17, Proceedings
The development and convergence of computing, telecommunications and information systems has already led to a revolution in the way that we work, communicate with each other, buy goods and use services, and even in the way that we entertain and educate ourselves.The revolution continues, and one of its results is that large volumes of information will increasingly be held in a form which is more natural for users than the data presentation formats typical of computer systems of the past. Natural language processing (NLP) is crucial in solving these problems, and language technologies will make an indispensable contribution to the success of information systems. We hope that NLDB 2005 was a modest contribution to this goal. NLDB 2005 contributed to advancing the goals and the high international standing of these conferences, largely due to its Program Committee, composed of renowned researchers in the field of natural language processing and inf- mation system engineering. Papers were reviewed by three reviewers from the Program Committee. This clearly contributed to the significant number of - pers submitted (95). Twenty-nine were accepted as regular papers, while 18 were accepted as short papers.
Nanoscience : Nanotechnologies and Nanophysics
Nanotechnologies and nanosciences are a fast-developing field of research, which sit at the point of convergence of several disciplines (physics, chemistry, biology, mechanics, etc.). This practically-oriented overview is designed to provide students and researchers with essential information on both the tools of manufacture and specific features of the nanometric scale, as well as applications within the most active fields (electronics, magnetism, information storage, biology).
Multinational Enterprises, Foreign Direct Investment and Growth in Africa : South African Perspectives
How can Africa, the world’s most lagging region, benefit from globalisation and achieve sustained economic growth? Africa needs greater investment by Multinational Enterprises (MNEs) to improve competitiveness and generate more growth through positive spill-over effects. Despite the fact that Africa’s returns on investment averaged 29% since 1990, Africa has gained merely 1% of global Foreign Direct Investment (FDI) flows. The challenge for African countries is how to be a more desirable destination for FDI. The study integrates three currents of economic research, namely from the literature on (endogenous) economic growth, convergence and regional integration, the explanations for Africa’s poor growth and the growing understanding of the role of MNEs in a global economy. The empirical side of the book is based on an econometric study of the determinants of FDI in Africa as well as a detailed firm-level survey conducted in 2000.
Monetary Policy and the German Unemployment Problem in Macroeconomic Models : Theory and Evidence
Having the high unemployment in Germany in mind, this book discusses how macroeconomic theory has evolved over the past forty years. It shows that in recent years a convergence has taken place, with modern models embodying a Keynesian transmission mechanism, monetarist policy implication, and modeling techniques inspired by new classical economics and real business cycle theory. It also probes in which direction models may be extended from here. Empirically, the book uses different econometric techniques to investigate the relevance and implications of different macroeconomic theories for German data. A key question this book investigates is the role of demand and supply side conditions for the increase in the German unemployment rate. On a policy level, the book relates the implications of the different theories to the ongoing debate on the appropriate roles of demand and supply side policies for curing the German unemployment problem.
Mobility Aware Technologies and Applications ; 2nd International Workshop, MATA 2005, Montreal, Canada, October 17 -- 19, 2005, Proceedings
The beginning of the twenty-first century is characterized by global markets, and the mobility of people is becoming an important fact of life. Consequently, the mobile user is demanding appropriate technical solutions to make use of customized information and communication services. In this context the notion of next-generation networks (NGNs), which are driven by the convergence of the entertainment sector, the mobile Internet, and fixed/mobile telecommunications, is emerging. Such NGNs are aggregating a variety of different access networks and supporting the seamless connection of an open set of end-user devices, and due to the adoption of an all-IP network paradigm they enable a much better integration of voice and data services. Coincidently the buzzword ‘fixed mobile convergence’ (FMC) describes the current trend towards providing common services across fixed and mobile networks resulting in the medium term in the full integration of fixed and mobile telecommunication networks. The adoption of appropriate middleware technologies and the provision of - called service delivery platforms driven by the ongoing innovation in the field of information technologies provides today the technical foundation for supporting terminal, personal and service mobility and thus the implementation of real seamless information and communication services. Furthermore, users are nowadays looking, in light of an omnipresent service environment, for a much higher degree of customization and context awareness in the services they use. The papers in this volume look at these enabling mobility-aware technologies and their use for implementing mobility-aware and context-aware applications.
Microfinance, EU structural funds and capacity building for managing authorities : A comparative analysis of European convergence regions
Presents a study of capacity building and structural funds in public managing authorities for the microcredit sector. It presents two surveys to highlight the strengths and weaknesses of the managing authorities' capacity building. The first survey investigates the authorities' need for and interests in capacity building activities, assessing the areas in which capacity building support is needed, and explores the different types of support offered. The second survey analyses the results of the microcredit and microfinance programming activity, investigating its target groups and other operational features. It examines the key monitoring and reporting issues involved in this activity, before analysing the regulatory framework of the microcredit and microfinance sector.
Metric Spaces
The abstract concepts of metric ces are often perceived as difficult. This book offers a unique approach to the subject which gives readers the advantage of a new perspective familiar from the analysis of a real line. Rather than passing quickly from the definition of a metric to the more abstract concepts of convergence and continuity, the author takes the concrete notion of distance as far as possible, illustrating the text with examples and naturally arising questions. Attention to detail at this stage is designed to prepare the reader to understand the more abstract ideas with relative ease.
Measure Theory and Probability Theory
The book can be used as a text for a two semester sequence of courses in measure theory and probability theory, with an option to include supplemental material on stochastic processes and special topics.Prerequisites are kept to the minimal level of an understanding of basic real analysis concepts such as limits, continuity, differentiability, Riemann integration, and convergence of sequences and series. A review of this material is included in the appendix. The book starts with an informal introduction that provides some heuristics into the abstract concepts of measure and integration theory, which are then rigorously developed. The first part of the book can be used for a standard real analysis course for both mathematics and statistics Ph.D. students as it provides full coverage of topics such as the construction of Lebesgue-Stieltjes measures on real line and Euclidean spaces, the basic convergence theorems, L^p spaces, signed measures, Radon-Nikodym theorem, Lebesgue's decomposition theorem and the fundamental theorem of Lebesgue integration on R, product spaces and product measures, and Fubini-Tonelli theorems. It also provides an elementary introduction to Banach and Hilbert spaces, convolutions, Fourier series and Fourier and Plancherel transforms.
Measure Theory
This book gives a systematic presentation of modern measure theory as it has developed over the past century and offers three levels of presentation: a standard university graduate course, an advanced study containing some complements to the basic course (the material of this level corresponds to a variety of special courses), and, finally, more specialized topics partly covered by more than 850 exercises. Bibliographical and historical comments and an extensive bibliography with 2000 works covering more than a century are provided.
Introduction to Calculus and Classical Analysis
This text is intended for an honors calculus course or for an introduction to analysis. Involving rigorous analysis, computational dexterity, and a breadth of applications, it is ideal for undergraduate majors. This second edition includes corrections as well as some additional material.The text is completely self-contained and starts with the real number axioms; the integral is defined as the area under the graph, while the area is defined for every subset of the plane; there is a heavy emphasis on computational problems.
Interior Point Methods for Linear Optimization
Linear Optimization (LO) is one of the most widely applied and taught techniques in mathematics, with applications in many areas of science, commerce and industry. The dramatically increased interest in the subject is due mainly to advances in computer technology and the development of Interior Point Methods (IPMs) for LO. This book provides a unified presentation of the field. The authors present a self-contained comprehensive interior point approach to both the theory of LO and algorithms for LO (design, convergence, complexity, asymptotic behaviour and computational issues). A common thread throughout the book is the role of strictly complementary solutions, which play a crucial role in the interior point approach and distinguishes the new approach from the classical Simplex-based approach
Integration, Growth, and Cohesion in an Enlarged European Union
This book’s thirteen contributions bring together the results of recent research on determinants of regional specialization, growth, and convergence in the context of European integration. They offer fresh theoretical and empirical evidence on patterns of regional production structures, specialization, regional disparities, convergence and divergence processes, and evaluation of cohesion policies on both current and future European Union (EU) member states in the context of increased integration. These subjects are addressed in both individual and cross-country analysis using innovative methodologies. They examine structural changes and economic performance differentials across regions and countries in an enlarged EU as well as on evaluating existing policies aimed at reducing economic imbalances.
Institutional Context of Education Systems in Europe : A Cross-Country Comparison on Quality and Equity
In this volume, the authors take up the challenge of considering what a European ‘settlement’ might look like. In doing so, they take into account worldwide trends and the increasing evidence of convergence across educational systems. The outcomes of comparative analyses seem to suggest that strong education systems in terms of finance, governance and choice could be preferable. To a greater or lesser extent, therefore, all the systems of education currently in use in Europe face some common challenges. The way in which these challenges are addressed will determine the future of these systems.
Information theory and machine learning
The recent successes of machine learning, especially regarding systems based on deep neural networks, have encouraged further research activities and raised a new set of challenges in understanding and designing complex machine learning algorithms. New applications require learning algorithms to be distributed, have transferable learning results, use computation resources efficiently, convergence quickly on online settings, have performance guarantees, satisfy fairness or privacy constraints, incorporate domain knowledge on model structures, etc. A new wave of developments in statistical learning theory and information theory has set out to address these challenges.

Information networking : Convergence in broadband and mobile networking ; International conference, ICOIN 2005, Jeju Island, Korea, January 31 - February 2, 2005, Proceedings
Welcome to ICOIN 2005,the International Conference on Information Netwo- ing, held at Ramada Plaza Jeju Hotel, Jeju Island, Korea during January 31– February2,2005.ICOIN2005followedthesuccessofpreviousconferences.Since 1986, the conference has provided a technical forum for various issues in inf- mation networking. The theme of each conference re?ects the historic events in the computer communication industry. (Please refer to www.icoin2005.or.kr for details.) The theme of ICOIN 2004, “Convergence in Broadband and Mobile Networking,” was used again for ICOIN 2005 since we believed it was ongoing. This year we received 427 submissions in total, which came from 22 co- tries. Upon submission, authors were asked to select one of the categories listed in the Call for Papers. The most popular category chosen was network se- rity, followed by mobile networks and wireless LANs. Other areas with strong showings included QoS and resource management, ad hoc and sensor networks, and wireless multimedia systems. From the outset, we could see where recent research interest lay and could make sure that the theme was still going in the right direction.
