This book highlights the estimate of epidemic characteristics for
different countries/regions in the world with the use of known SIR
(susceptible-infected-removed) model for the dynamics of the
epidemic, the known exact solution of the linear differential
equations and statistical approach developed before. The COVID-19
pandemic is of great interest to researchers due to its high
mortality and a negative impact to the world economy. Correct
simulation of the pandemic dynamics needs complicated mathematical
models and many efforts for unknown parameters identification. The
simple method of detection of the new pandemic wave is proposed and
SIR model generalized. The hidden periods, epidemic durations,
final numbers of cases, the effective reproduction numbers and
probabilities of meeting an infected person are presented for
countries like USA, Germany, UK, the Republic of Korea, Italy,
Spain, France, the Republic of Moldova, Ukraine, and for the world.
The presented information is useful to regulate the quarantine
activities and to predict the medical and economic consequences of
different/future pandemics.

This collection is dedicated to the 70th jubilee of Yu. N.
Savchenko, and presents experimental, theoretical, and numerical
investigations written by an international group of well-known
authors. The contributions solve very important problems of the
high-speed hydrodynamics, such as supersonic motion in water, drag
diminishing, dynamics and stability of supercavitating vehicles,
water entry and hydrodynamic performances of hydrofoils, ventilated
cavities after a disc and under the ship bottom.
The book is written for researches, scientists, engineers, and
students interested in problems of hydromechanics."
