Skew-Elliptical Distributions and Their Applications - - Bog - Taylor & Francis Ltd - Plusbog.dk

Skew-Elliptical Distributions and Their Applications - - Bog - Taylor & Francis Ltd - Plusbog.dk

This book reviews the state-of-the-art advances in skew-elliptical distributions and provides many new developments in a single volume, collecting theoretical results and applications previously scattered throughout the literature. The main goal of this research area is to develop flexible parametric classes of distributions beyond the classical normal distribution. The book is divided into two parts. The first part discusses theory and inference for skew-elliptical distribution. The second part examines applications and case studies, including areas such as economics, finance, oceanography, climatology, environmetrics, engineering, image processing, astronomy, and biomedical science.

Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers - Akhilesh Mimani - Bog - Springer Verlag, Singapore - Plusbog.dk

Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers - Akhilesh Mimani - Bog - Springer Verlag, Singapore - Plusbog.dk

This book presents a three-dimensional analysis of acoustic wave propagation in an elliptical waveguide, and applies the equations and concepts to design axially short elliptical end-chamber muffler configurations which are an important component of a complex multi-pass muffler used in a modern-day automotive exhaust system. A general solution of the Helmholtz equation in elliptical cylindrical co-ordinates is presented in terms of the Mathieu and modified Mathieu modal functions. This is followed by the tabulation and analysis, for the first time, of the non-dimensional resonance frequencies of the transverse modes of a rigid-wall elliptical waveguide for a complete range of aspect ratio. The modal shape patterns of the first few circumferential, radial and cross-modes are examined with particular attention to the pressure nodal ellipses and hyperbolae. An analytical formulation is then outlined for characterizing a single-inlet and single-outlet elliptical muffler with the inlet located on the end face and the outlet located either on the end face or side-surface. The ensuing chapter is devoted toward analyzing the Transmission Loss (TL) performance of different short end-chamber mufflers, namely (a) the straight-flow configuration having ports located on the opposite face, (b) the flow-reversal configuration with ports located on the same end face and (c) configuration with inlet port on the end face and outlet on the side surface. Design guidelines are formulated in terms of the optimal location of inlet and outlet ports which suppresses the deteriorating influence of certain higher-order modes, thereby delivering a broadband TL performance. Directions for future work are discussed toward the end. In summary, this book is a one-stop solution for a practicing automotive engineer designing mufflers, for an applied mathematician studying wave propagation in elliptical geometries, and also as a niche area within noise control engineering.

Kant's Elliptical Path - Karl (university Of Notre Dame) Ameriks - Bog - Oxford University Press - Plusbog.dk

Kant's Elliptical Path - Karl (university Of Notre Dame) Ameriks - Bog - Oxford University Press - Plusbog.dk

Kant''s Elliptical Path explores the main stages and key concepts in the development of Kant''s Critical philosophy, from the early 1760s to the 1790s. Karl Ameriks provides a detailed and concise account of the main ways in which the later Critical works provide a plausible defence of the conception of humanity''s fundamental end that Kant turned to after reading Rousseau in the 1760s. Separate essays are devoted to each of the three Critiques, as well as to earlier notes and lectures and several of Kant''s later writings on history and religion. A final section devotes three chapters to post-Kantian developments in German Romanticism, accounts of tragedy up through Nietzsche, and contemporary philosophy. The theme of an elliptical path is shown to be relevant to these writers as well as to many aspects of Kant''s own life and work.The topics of the book include fundamental issues in epistemology and metaphysics, with a new defense of the Amerik''s ''moderate'' interpretation of transcendental idealism. Other essays evaluate Kant''s concept of will and reliance on a ''fact of reason'' in his practical philosophy, as well as his critique of traditional theodicies, and the historical character of his defense of religion and the concepts of creation and hope within ''the boundaries of mere reason''. Kant''s Elliptical Path will be of value to historians of modern philosophy and Kant scholars, while its treatment of several literary figures and issues in aesthetics, politics, history, and theology make it relevant to readers outside of philosophy.
