Robust Adaptive Beamforming
Автор: Jian Li
Год издания: 0000
The latest research and developments in robust adaptive beamforming Recent work has made great strides toward devising robust adaptive beamformers that vastly improve signal strength against background noise and directional interference. This dynamic technology has diverse applications, including radar, sonar, acoustics, astronomy, seismology, communications, and medical imaging. There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids. Robust Adaptive Beamforming compiles the theories and work of leading researchers investigating various approaches in one comprehensive volume. Unlike previous efforts, these pioneering studies are based on theories that use an uncertainty set of the array steering vector. The researchers define their theories, explain their methodologies, and present their conclusions. Methods presented include: * Coupling the standard Capon beamformers with a spherical or ellipsoidal uncertainty set of the array steering vector * Diagonal loading for finite sample size beamforming * Mean-squared error beamforming for signal estimation * Constant modulus beamforming * Robust wideband beamforming using a steered adaptive beamformer to adapt the weight vector within a generalized sidelobe canceller formulation Robust Adaptive Beamforming provides a truly up-to-date resource and reference for engineers, researchers, and graduate students in this promising, rapidly expanding field.

Adaptive Asset Allocation. Dynamic Global Portfolios to Profit in Good Times - and Bad
Автор: Adam Butler
Год издания:
Build an agile, responsive portfolio with a new approach to global asset allocation Adaptive Asset Allocation is a no-nonsense how-to guide for dynamic portfolio management. Written by the team behind Gestaltu.com, this book walks you through a uniquely objective and unbiased investment philosophy and provides clear guidelines for execution. From foundational concepts and timing to forecasting and portfolio optimization, this book shares insightful perspective on portfolio adaptation that can improve any investment strategy. Accessible explanations of both classical and contemporary research support the methodologies presented, bolstered by the authors' own capstone case study showing the direct impact of this approach on the individual investor. Financial advisors are competing in an increasingly commoditized environment, with the added burden of two substantial bear markets in the last 15 years. This book presents a framework that addresses the major challenges both advisors and investors face, emphasizing the importance of an agile, globally-diversified portfolio. Drill down to the most important concepts in wealth management Optimize portfolio performance with careful timing of savings and withdrawals Forecast returns 80% more accurately than assuming long-term averages Adopt an investment framework for stability, growth, and maximum income An optimized portfolio must be structured in a way that allows quick response to changes in asset class risks and relationships, and the flexibility to continually adapt to market changes. To execute such an ambitious strategy, it is essential to have a strong grasp of foundational wealth management concepts, a reliable system of forecasting, and a clear understanding of the merits of individual investment methods. Adaptive Asset Allocation provides critical background information alongside a streamlined framework for improving portfolio performance.
Robust Equity Portfolio Management. Formulations, Implementations, and Properties using MATLAB
Автор: Frank J. Fabozzi
Год издания:
A comprehensive portfolio optimization guide, with provided MATLAB code Robust Equity Portfolio Management + Website offers the most comprehensive coverage available in this burgeoning field. Beginning with the fundamentals before moving into advanced techniques, this book provides useful coverage for both beginners and advanced readers. MATLAB code is provided to allow readers of all levels to begin implementing robust models immediately, with detailed explanations and applications in the equity market included to help you grasp the real-world use of each technique. The discussion includes the most up-to-date thinking and cutting-edge methods, including a much-needed alternative to the traditional Markowitz mean-variance model. Unparalleled in depth and breadth, this book is an invaluable reference for all risk managers, portfolio managers, and analysts. Portfolio construction models originating from the standard Markowitz mean-variance model have a high input sensitivity that threatens optimization, spawning a flurry of research into new analytic techniques. This book covers the latest developments along with the basics, to give you a truly comprehensive understanding backed by a robust, practical skill set. Get up to speed on the latest developments in portfolio optimization Implement robust models using provided MATLAB code Learn advanced optimization methods with equity portfolio applications Understand the formulations, performances, and properties of robust portfolios The Markowitz mean-variance model remains the standard framework for portfolio optimization, but the interest in—and need for—an alternative is rapidly increasing. Resolving the sensitivity issue and dramatically reducing portfolio risk is a major focus of today's portfolio manager. Robust Equity Portfolio Management + Website provides a viable alternative framework, and the hard skills to implement any optimization method.
The Leader's Dilemma. How to Build an Empowered and Adaptive Organization Without Losing Control
Автор: Jeremy Hope
Год издания:
Drawing on their work on performance management within the ‘beyond budgeting’ movement over the past ten years, including many interviews and case studies, Jeremy Hope, Peter Bunce and Franz Roosli set out in this book an executive guide to building a new management model based on eight key change management issues: 1. Governance: From rules and budgets to purpose and values 2. Success: From fixed targets to relative improvement 3. Organization: From centralized functions to customer-oriented teams 4. Accountability: From narrow targets to holistic success criteria 5. Trust: From central control to local autonomy 6. Transparency: From closed information to open book management 7. Rewards: From individual incentives to team-based reward 8. Risk: From complying with rules to understanding pressure points This book is about rethinking how we manage organizations in a post-industrial, post credit crunch world where innovative management models represent the only remaining source of sustainable competitive advantage.[i] The changes suggested by the authors will enable and encourage a cultural climate change that will help organizations to attract and keep the best people as well as drive continuous innovation and growth. Above all, The CEO's Dilemma is about learning how to change business – based on best practice and innovation drawn from leaders world-wide who have built and managed successful organizations.
Business Darwinism: Evolve or Dissolve. Adaptive Strategies for the Information Age
Автор: Eric Marks A.
Год издания:
The survival of the fastest Information technology is now essential to business evolution. Companies that invest in IT as a future resource will live to see the future. The rest won't. The hard reality of the new «Information Darwinism,» a term coined by author Eric Marks, is brilliantly and provocatively described in e-Darwinism, a look at the make-or-break impact of IT on accelerating the global struggle for market share. The book offers a compelling look at just how the Internet has transformed business strategy and business strategy creation, IT strategy, and manufacturing strategy for manufacturing and service firms, and made significant inroads in driving revenue enhancement and cost savings as well as reducing a firm's time to market. The book also describes how much the ability to leverage IT has become a requirement for measuring-and selecting-future leaders.
