A new and finite family of solutions of hydrodynamics: Part II: Advanced estimate of initial energy densities

We derive a new, exact formula for the estimate of the initial energy densities from a new family of finite and exact solution of relativistic perfect fluid hydrodynamics. The new formula depends non-trivially on the speed of sound and on the shape or width parameter of the measured (pseudo)rapidity distribution.Comment: Invited talk of G.

A new and finite family of solutions of hydrodynamics: Part III: Advanced estimate of the life-time parameter

We derive a new formula for the longitudinal HBT-radius of the two particle Bose-Einstein correlation function from a new family of finite and exact, accelerating solution of relativistic perfect fluid hydrodynamics for a temperature independent speed of sound. The new result generalizes the Makhlin-Sinyukov and Herrmann-Bertsch formulae and leads to an advanced life-time estimate of high energy heavy ion and proton-proton collisions

Scaling properties of spectra in new exact solutions of rotating, multi-component fireball hydrodynamics

We describe fireballs that rehadronize from a perfect fluid of quark matter, characterized by the lattice QCD equation of state, to a chemically frozen, multi-component mixture, that contains various kinds of observable hadrons. For simplicity and clarity, we apply a non-relativistic approximation to describe the kinematics of this expansion. Unexpectedly, we identify a secondary explosion that may characterize fireball hydrodynamics at the QCD critical point. After rehadronization, the multi-component mixture of hadrons keeps on rotating and expanding together, similarly to a single component fluid. After kinetic freeze-out, the effective temperature $T_{i}$ of the single-particle spectra of hadron type $h_i$ is found to be a sum of the kinetic freeze-out temperature $T_f$ (that is independent of the hadron type $h_i$) and a term proportional to the mass $m_i$ of hadron type $h_i$. The coefficient of proportionality to $m_i$ is also found to be independent of the hadron type $h_i$ but be dependent on the radial flow and vorticity of collective dynamics.Comment: 12 pages, 2 figures, 6 tables, invited talk of G.

Sensitivity Analysis for Condominium Lightning Protection Risk Analysis

Today we live in an accelerated world. In our environment there are more facilities to serve our needs than ever before, and today’s devices have multiple functions, and probably they will gain new functions as well. They are called smart devices. Smartphones, tablets, smart TV-s and potential smart vehicles will create a new environment. As a result of the continuous development of human living communities (villages, towns and settlements), the dominant usage of smart tools and technologies already represents a new quality level (Smart City). These new devices require a new level of lightning protection. Natural forces endanger buildings as well as human lives. The protection of artificially created objects and of the built environment has always played a prominent role, and nowadays, one of its main areas is the lightning protection of structures. The calculation of the lightning protection is based on the MSZ EN 62305 [1] standard. In the past, several changes were made in the standards and decrees [2], and now the current standard is the MSZ EN 62305. It contains the exact mathematical methods of risk assessment using the parameters of buildings and their installations (e.g. lightning protection installations, cables, flooring etc.). The present research aims to identify the relationships between output parameters determined by the input parameters based on the current standards, and the identification of risks by their analysis in different types of buildings

Post modern identity : "in between" real and virtual

The article focus on the phenomena of the "radical change" (transformation) brought by new ICT technologies, associated with the information and communication revolution, both on the level of the collective: bringing disruptive changes within economic, social and cultural sphere, and on the level of the individual, evoking fundamental, yet subtle, changes within our psyche impacting our identity (ies). The multiple scientific discourses, when analyzing the impact of new technologies, usually focus on changes in the economic, social or cultural sphere, defining them within the context of its semantic field (resulting different explanatory models built around different theoretical concepts, together with the accompanying different methodology). The main hypothesis of the "radical change" (transformation) brought by new technologies, usually described in reference to new paradigm change, refers to constantly increasing impact (direct mediation) of ICT technologies in almost all spheres of our lives: social, economical and cultural, but hardly ever discuss the extremely subtle reconfiguration of our psychological space made under the influence of new technologies. As such the article focuses mainly the impact of new technologies upon the psyche and post-modern identity, trying to fully grasp and understand both the visible (direct) and the invisible (subtle) changes, from the perspective of psychological approach, with special reference to Jung’s analytical psychology. The core element (novelty) is the attempt to fully grasp (understand) the phenomena of moving (living) ‘in between’ real and virtual (identity/ environment), mainly from the point view (implications) of psychological as well as philosophical (ontological), not as in majority of cases (discourses) from the technological, economical, sociological perspective. Cultural anthropology evokes the concept of liminality to denominate the boundaries between two different states : functioning within the existing normative (institutional) governance and stepping outside or aside of it, meaning suspension of the existing norms and standards (and break in or pause within the existing culture). The post-modern individual is somehow forced to move ‘in between’ and experience two different environments simultaneously - the physical environment, embedded in real space and time continuum, where we live at the very moment and digital environment created by new technologies (virtual and/or digital space). As such this continuous transition from reality to virtuality evokes the characteristics (attributes) of the liminal experience. Critical analysis of the defined phenomena implies the need of interdisciplinary approach based on the comparative methodology, both from the point view of theoretical discourses as well as more empirical approach, based mainly on the interdisciplinary approach of Jungian Analytical Psychology, as the outlined theme moves ‘in between’ new technologies, culture (as well as economy or social science) and psychology
