In this book the authors investigate, from the numerical perspective, the 18D core dynamics of a theoretical 39D representation of an applied Keynesian disequilibrium model of monetary growth of a small open economy. After considering the model from the viewpoint of national accounting, the authors provide a compact description of the intensive form of the model, its laws of motion and accompanying algebraic expressions and its unique interior steady state solution. The authors then give a survey of various types of subsystems that can be isolated from the integrated 18D dynamics by means of suitable assumptions. These subsystems and the full 18D dynamics are investigated and compared in the remainder of the paper from the perspective of bifurcation diagrams that separate situations of asymptotic stability from stable cyclical behaviour as well as pure explosiveness. In this way the authors lay the foundations for an analysis of business cycle fluctuations in applicable high order macrosystems, which will show, in contrast to what is generally believed to characterise such structural macroeconometric models, that applied integrated macrodynamical systems can have a variety of interesting more or less complex attractors which are surrounded by more or less long-phase transient behaviour. Such attractors are obtained in particular when locally explosive situations are turned into bounded dynamics by the addition of specifically tailored extrinsic behavioural non-linearities. The authors establish a Keynesian theory of endogenously generated business cycles where turning points are caused by globally non-linear behaviour, rather than by complex eigenvalues, around the steady state position of the economy.

Multibeam Phased Array Antennas as Satellite Constellation Ground Station (Modern Antenna)


Free Download Multibeam Phased Array Antennas as Satellite Constellation Ground Station (Modern Antenna) by Guolong He, Xin Gao, Rentian Zhang
English | November 22, 2023 | ISBN: 9819979099 | 113 pages | MOBI | 16 Mb
This book focuses on the multi-beam phased array antenna as a satellite ground station. As there are already many excellent books on phased array antennas in the literature, this book focuses mainly on some engineering practices and fills the gap between principles and practices, such as array excitation error impact analysis and calibration methods, array geometry design for hemispherical coverage, multiple beam resource management, etc. This book is particularly suitable for readers interested in satellite constellation design or satellite ground station design. This book also benefits researchers and engineers in the fields of phased array antennas, aerospace engineering, telecommunications, etc.
