A spline adaptive filter (SAF) based nonlinear active noise control (ANC) system is proposed in this paper. The SAF consists of a linear network of adaptive weights in a cascade with an adaptive nonlinear network. The nonlinear network, in turn consists of an adaptive look-up table followed by a spline interpolation network and forms an adaptive activation function. An update rule has been derived for the proposed ANC system, which not only updates the weights of the linear network, but also updates the nature of the activation function. Linear Network is based on improvement in FxLMS algorithm. FxLMS algorithm is used because it is computationally simple like the most commonly used Least Mean Square (LMS) algorithm. In addition, it includes secondary path effects. To make the FxLMS algorithm more effective, the secondary path estimation should be more precise and accurate. The nonlinear function involved in the adaptation process is based on a spline function that can be modified during learning. The spline control points are adaptively changed using gradient-based techniques. B-splines and Catmull-Rom splines are used, because they allow imposing simple constraints on control parameters. This new kind of adaptive function is then applied to the output of a linear adaptive filter and it is used for the identification of Wiener-type nonlinear systems. In addition, we derive a simple form of the adaptation algorithm and an upper bound on the choice of the step-size. An extensive simulation study has been conducted to evaluate the noise mitigation performance of the proposed scheme and the new method has been shown to provide improved noise cancellation efficiency with a lesser computational load in comparison with other popular ANC systems.

Recent developments such as the invention of powerful turbo-decoding and irregular designs, together with the increase in the number of potential applications to multimedia signal compression, have increased the importance of variable length coding (VLC). Providing insights into the very latest research, the authors examine the design of diverse near-capacity VLC codes in the context of wireless telecommunications. The book commences with an introduction to Information Theory, followed by a discussion of Regular as well as Irregular Variable Length Coding and their applications in joint source and channel coding. Near-capacity designs are created using Extrinsic Information Transfer (EXIT) chart analysis. The latest techniques are discussed, outlining radical concepts such as Genetic Algorithm (GA) aided construction of diverse VLC codes. The book concludes with two chapters on VLC-based space-time transceivers as well as on frequency-hopping assisted schemes, followed by suggestions for future work on the topic. Surveys the historic evolution and development of VLCs Discusses the very latest research into VLC codes Introduces the novel concept of Irregular VLCs and their application in joint-source and channel coding

Maps capture data expressing the economic complexity of countries from Albania to Zimbabwe, offering current economic measures and as well as a guide to achieving prosperity Why do some countries grow and others do not? The authors of The Atlas of Economic Complexity offer readers an explanation based on "Economic Complexity," a measure of a society's productive knowledge. Prosperous societies are those that have the knowledge to make a larger variety of more complex products. The Atlas of Economic Complexity attempts to measure the amount of productive knowledge countries hold and how they can move to accumulate more of it by making more complex products. Through the graphical representation of the "Product Space," the authors are able to identify each country's "adjacent possible," or potential new products, making it easier to find paths to economic diversification and growth. In addition, they argue that a country's economic complexity and its position in the product space are better predictors of economic growth than many other well-known development indicators, including measures of competitiveness, governance, finance, and schooling. Using innovative visualizations, the book locates each country in the product space, provides complexity and growth potential rankings for 128 countries, and offers individual country pages with detailed information about a country's current capabilities and its diversification options. The maps and visualizations included in the Atlas can be used to find more viable paths to greater productive knowledge and prosperity.

In Complexity and Postmodernism, Paul Cilliers explores the idea of complexity in the light of contemporary perspectives from philosophy and science. Cilliers offers us a unique approach to understanding complexity and computational theory by integrating postmodern theory (like that of Derrida and Lyotard) into his discussion. Complexity and Postmodernism is an exciting and an original book that should be read by anyone interested in gaining a fresh understanding of complexity, postmodernism and connectionism.

Sociological Theory and the Capability Approach connects normative strands of sociological theory to the fusion of ethics and economics proposed by Amartya Sen’s and Martha Nussbaum’s capability approach. Spanning classical (Hegel, Marx, Durkheim, Scheler, Weber) and contemporary debates (Parsons, Giddens, Luhmann) it identifies areas that bridge the current gap between sociology and capability approach. It thus builds on explanatory and normative concerns shared by both traditions. Engaging readers from sociology and capability approach, Spiros Gangas suggests that the proposed dialogue should be layered along the main areas of value theory, economy and society, extending this inquiry into the normative meaning attached to being human. To this end, the book reconstructs the notion of agency along the tracks of Nussbaum’s central human capabilities, considering also alienation and the sociology of emotions. It concludes by addressing the capability approach through the lens of social institutions before it takes up the challenge of ideological fundamentalism and how it can be effectively confronted by capability approach. This original book provides a fresh perspective on capability approach as it embeds it in the rich pool of sociological theory’s accomplishments. As an exercise in theoretical and normative convergence, it will be required reading for academics and students in social theory, cultural theory, philosophy and human development studies.

Applying the demand-led growth models framework, this book examines the recent macroeconomic performance of the key Mediterranean economies – Italy, Spain, Portugal and Greece – including the responses to the economic and financial crisis (2008), the debt crisis (2010) and the COVID-19 crisis (2020). As the book explains, the central idea of the growth model approach is that the widespread breakdown of the old labor institutions, such as the existence of strong unions, centralized wage bargaining and the participation of the workforce in corporate governance, has led to a fall in the wage share and a rise in inequality in most advanced economies. Thus, the two main contemporary growth models are usually characterized as debt-led and export-led. In both models, the same processes that cumulatively drive growth, such as over-consumption, also simultaneously undermine the foundations on which this expansion takes hold. The book examines the extent to which these processes hold true for Mediterranean economics and explores the key factors of their economies including productive capacity, growth of aggregate demand components, wage-led or profit-led regimes, personal income distribution, the foreign sector, the financial sector, labor relations, the labor market and welfare states. In particular, the book examines whether policy responses and state interventions in recent years have led to a divergence between the economies. To what extent are these changes transforming the existing growth models? Are we facing a change in the Mediterranean model or the disappearance of the Mediterranean bloc as a whole? This book marks a significant addition to the literature on the economics and politics of Southern Europe and the fields of political economy, comparative economics, and macroeconomics more broadly.
