Book Synopsis A Closed Form Multivariate Linear Filter by : Mr.Francis Vitek
Download or read book A Closed Form Multivariate Linear Filter written by Mr.Francis Vitek and published by International Monetary Fund. This book was released on 2018-12-10 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper considers the problem of jointly decomposing a set of time series variables into cyclical and trend components, subject to sets of stochastic linear restrictions among these cyclical and trend components. We derive a closed form solution to an ordinary problem featuring homogeneous penalty term difference orders and static restrictions, as well as to a generalized problem featuring heterogeneous penalty term difference orders and dynamic restrictions. We use our Generalized Multivariate Linear Filter to jointly estimate potential output, the natural rate of unemployment and the natural rate of interest, conditional on selected equilibrium conditions from a calibrated New Keynesian model.

Book Synopsis Measuring the Stances of Monetary and Fiscal Policy by : Mr. Francis Vitek
Download or read book Measuring the Stances of Monetary and Fiscal Policy written by Mr. Francis Vitek and published by International Monetary Fund. This book was released on 2023-05-12 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: We derive measures of the stances of monetary and fiscal policy within the framework of an empirically plausible extension of the basic New Keynesian model, and jointly estimate them for the United States using a closed form multivariate linear filter. Our theoretical analysis reveals that the neutral stance of monetary policy — as measured by the real natural rate of interest — depends on the stance of fiscal policy, which in turn depends on the composition and expected timing of structural changes in the fiscal instruments. Our empirical application finds that accounting for fiscal policy significantly alters the estimated stance of monetary policy, and that the so-called fiscal impulse is a poor proxy for the stance of fiscal policy.
Book Synopsis New Trends in Optimal Filtering and Control for Polynomial and Time-Delay Systems by : Michael Basin
Download or read book New Trends in Optimal Filtering and Control for Polynomial and Time-Delay Systems written by Michael Basin and published by Springer. This book was released on 2008-09-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 0. 1 Introduction Although the general optimal solution of the ?ltering problem for nonlinear state and observation equations confused with white Gaussian noises is given by the Kushner equation for the conditional density of an unobserved state with respect to obser- tions (see [48] or [41], Theorem 6. 5, formula (6. 79) or [70], Subsection 5. 10. 5, formula (5. 10. 23)), there are a very few known examples of nonlinear systems where the Ku- ner equation can be reduced to a ?nite-dimensional closed system of ?ltering eq- tions for a certain number of lower conditional moments. The most famous result, the Kalman-Bucy ?lter [42], is related to the case of linear state and observation equations, where only two moments, the estimate itself and its variance, form a closed system of ?ltering equations. However, the optimal nonlinear ?nite-dimensional ?lter can be - tained in some other cases, if, for example, the state vector can take only a ?nite number of admissible states [91] or if the observation equation is linear and the drift term in the 2 2 state equation satis?es the Riccati equation df /dx + f = x (see [15]). The complete classi?cation of the “general situation” cases (this means that there are no special - sumptions on the structure of state and observation equations and the initial conditions), where the optimal nonlinear ?nite-dimensional ?lter exists, is given in [95].

Book Synopsis Multiple Muscle Systems by : Jack M. Winters
Download or read book Multiple Muscle Systems written by Jack M. Winters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable pertur bations, has a long history. However, despite a history of magnificent sculptures and drawings of the human body which vividly depict muscle ac tivity and interaction, until more recent times our state of knowledge of human movement was rather primitive. During the past century this has changed; we now have developed a considerable database regarding the com position and basic properties of muscle and nerve tissue and the basic causal relations between neural function and biomechanical movement. Over the last few decades we have also seen an increased appreciation of the impor tance of musculoskeletal biomechanics: the neuromotor system must control movement within a world governed by mechanical laws. We have now col lected quantitative data for a wealth of human movements. Our capacity to understand the data we collect has been enhanced by our continually evolving modeling capabilities and by the availability of computational power. What have we learned? This book is designed to help synthesize our current knowledge regarding the role of muscles in human movement. The study of human movement is not a mature discipline.

Book Synopsis Analysis and Synthesis of Delta Operator Systems by : Hongjiu Yang
Download or read book Analysis and Synthesis of Delta Operator Systems written by Hongjiu Yang and published by Springer. This book was released on 2012-04-23 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to analysis and design on delta operator systems. When sampling is fast, a dynamical system will become difficult to control, which can be seen in wide real world applications. Delta operator approach is very effective to deal with fast sampling systems. Moreover, it is easy to observe and analyze the control effect with different sampling periods in delta operator systems. The framework of this book has been carefully constructed for delta operator systems to handle sliding mode control, time delays, filter design, finite frequency and networked control. These problems indeed are especially important and significant in automation and control systems design. Through the clear framework of the book, readers can easily go through the learning process on delta operator systems via a precise and comfortable learning sequence. Following this enjoyable trail, readers will come out knowing how to use delta operator approach to deal with control problems under fast sampling case. This book should be a good reference for academies, post-graduates scientists and engineers working in the field of control science and control engineering.
Book Synopsis Influence of Inter- and Intra-Synaptic Factors on Information Processing in the Brain by : Vito Di Maio
Download or read book Influence of Inter- and Intra-Synaptic Factors on Information Processing in the Brain written by Vito Di Maio and published by Frontiers Media SA. This book was released on 2019-10-14 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any brain activity relies on the interaction of thousands of neurons, each of which integrating signals from thousands of synapses. While neurons are undoubtedly the building blocks of the brain, synapses constitute the main loci of information transfer that lead to the emergence of neuronal code. Investigating synaptic transmission constitutes a multi-faceted challenge that brings together a large number of techniques and expertise ranging from experimental to computational approaches, bringing together paradigms spanning from molecular to neural network level. In this book, we have collected a series of articles that present foundational work aimed at shedding much-needed light on brain information processing, synaptic transmission and neural code formation. Some articles present analyses of regulatory mechanisms underlying neural code formation and its elaboration at the molecular level, while others use computational and modelling approaches to investigate, at synaptic, neuronal and inter-neuronal level, how the different mechanisms involved in information processing interact to generate effects like long-term potentiation (LTP), which constitutes the cellular basis of learning and memory. This collection, although not exhaustive, aims to present a framework of the most used investigational paradigms and showcase results that may, in turn, generate novel hypotheses and ideas for further studies and investigations.
Book Synopsis Hierarchical Voronoi Graphs by : Jan Oliver Wallgrün
Download or read book Hierarchical Voronoi Graphs written by Jan Oliver Wallgrün and published by Springer Science & Business Media. This book was released on 2009-11-28 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is space? Is there space when there are objects to occupy it or is there space only when there are no objects to occupy it? Can there be space without objects? These are old philosophical questions that concern the ontology of space in the philosophical sense of ‘ontology’ – what is the nature of space? Cognitive science in general and arti?cial intelligence in particular are less c- cerned with the nature of things than with their mental conceptualizations. In spatial cognition research we address questions like What do we know about space? How is space represented? What are the representational entities? What are the rep- sentational structures? Answers to these questions are described in what is called ontologies in arti?cial intelligence. Different tasks require different knowledge, and different representations of knowledge facilitate different ways of solving problems. In this book, Jan Oliver Wallgrün develops and investigates representational structures to support tasks of autonomous mobile robots, from the acquisition of knowledge to the use of this knowledge for navigation. The research presented is concerned with the robot mapping problem, the pr- lem of building a spatial representation of an environment that is perceived by s- sors that only provide incomplete and uncertain information; this information usually needs to be related to other imprecise or uncertain information. The routes a robot can take can be abstractly described in terms of graphs where alternative routes are represented by alternative branches in these route graphs.
