Equilibrium and quasi static dynamics of liquid, partially wetting solid surface

Series in Applied Mathematics and Mechanics, Volume 1, Institute of Mechanics - BAS, Sofia, 2011, 234 pp.


The aim of this book is to acquaint the reader with the variational derivation of the equations, describing the statics and dynamics of the three-phase system liquid/fluid/solid, which takes into account the existence of hysteresis of the equilibrium contact angle and the dissipation of energy when the contact line is moving. The effect of different possible realiza-tions of the heterogeneity and roughness of the solid substrate on the equilibrium shapes of a drop placed on it is studied numerically. The asymptotic and numerical solutions for the liq-uid motion are obtained for different three-phase systems taking into consideration the energy dissipation occurring when the contact line moves. A variational numerical method is devel-oped for the realization of the numerical studies which allows to treat real three-dimensional problems.

The material, presented in the book is based on previous studies of the authors pub-lished in renowned international journals.

Upper bounds on heat transport and energy dissipation in moving fluids

Series in Applied Mathematics and Mechanics, Volume 2, Institute of Mechanics - BAS, Sofia, 2011, 318 pp.


The aim of this book is to present the methods of the optimum theory of turbulence to the reader. The book consists of introductory part (up to chapter 3 inclusive) where the model equations of the hydrodynamics which are the basis for the optimum theory of turbulence are presented. In addition the two methods of the optimum theory of turbulence are discussed. The second part of the book is devoted to the upper bounds on the quantities connected to the thermal convection in a fluid layer without presence of rotation. The influence of rotation on the thermal convection is discussed in the third part of the book. In the same part one of the methods of the optimum theory of turbulence is illustrated on the basis of isothermal flow without presence of thermal convection.

The material presented in the book is based on studies of the author published in renowned international journals.

Nonlinear dynamics for marketing decisions. Part I. Dynamics of global brand values: Concepts and models,

Series in Applied Mathematics and Mechanics, Volume 8, Institute of Mechanics - BAS, Sofia, 2016, 145 pp.

We live in a world where disruptive technologies, rapid structural changes and economic turbulence are impacting the global economy by accelerating the rise of complexity. Complexity turns out to be a major force business must consider when developing and executing marketing strategies. It affects businesses both by delivering challenges and opening new opportunities which means that complexity radically changes the way business is managed. Globalisation is signified the quintessence of the last decade of the 20th century. Its effect on brands and branding strategies is outstanding. New brands are developed and launched as global brands, many traditionally local brands are sold or acquired, numerous rebranding strategies are realised, just to name a few of the subsequent outcomes of the globalisation process. This book presents an investigation of the dynamics of global brands values by applying the Zipf-Pareto law and the index of Sheppard. The research is focused on the top 100 global brands explored as a system of brands. It is assumed that there are variations in the factors which affect the distribution of global brands values as well as that these variations can be modelled by stochastic processes. The selection of a proper stochastic process instead of a model equation of factors affecting brand value serves as a starting point for the research methodology. The basic assumption states that the explanation of the distribution of global brands values needs only an implementation of a mathematical model based on the stochastic process with proper characteristics. The main research goal of the study is twofold. To understand: (1) if the state of equilibrium of the ranked global brands (based on their values) fits the power law, and (2) if the deviations are characterised by the index of Sheppard. Three research hypotheses are defined, based on the main research goal: RH1: The distribution of global brand values satisfies the Zipf-Pareto law. RH2: The identified three classes of global brands satisfy the Zipf-Pareto law. RH3: The system of global brands satisfies the primacy index of Sheppard.
