Social Equivalent of Free Energy

Characterisation of unbounded resources of a social system within the sociological interpretation has resulted in a large number of different notions, which are relevant in different situations. From the view point of statistical mechanics, these notions resemble free energy. In this paper the concept of social free energy is introduced and first steps toward its development presented. The social free energy is a function equal to physical free energy appropriately determined for the social system, with intrinsically sociological interpretation as a measure of social action obtainable in a given social system without changes in its structure. Its construction is a consequence of response of a social system to recognised parts of environment dynamics. It is argued that development of a social system response resembles exciting the normal modes of a general, physical system

Contribution to Quantification of Communication

Communication among humans is one of crucial human activities. Yet, its importance is not accompanied with the accurate and precise formal measure. Two starting points of this article are: (i) treating the communication among humans as a means to convene diverse individual and collective stimuli and needs; (ii) partitioning human environment into available, well-characterised communication modes, most of which makes possible mediated communication. Based on these starting points, a generic model of human communication between individuals and their environment is formulated and discussed. It is argued that there is a definite relation between the utilised communication modes and intensity of convened matter

Nanometarski kapacitori

Molecular-dynamics computer simulations which employ the embedded-atom potential show that nanowires of gold exist as multishelled structures. We simulate double-walled gold nanowires and calculate the capacitance of a finite nanometer-size cylindrical capacitor. For the sizes for which multishelled nanowires appear in simulations we find the capacitances below one attofarad.Računalne simulacije molekulskom dinamikom, koje primjenjuju višečestični potencijal, pokazuju da postoje višeslojne nanožice od zlata. Simulirali smo dvoslojne zlatne nanožice i izračunali kapacitet takvog konačnog cilindričnog kapacitora. Za veličine kapacitora koje se nalaze u simulacijama višeslojnih nanožica dobivamo kapacitete ispod jednog atofarada

Concept of Modular, Self-Supporting Cable for Powering the Hovering Unmanned Aerial Vehicle

Hovering unmanned aerial vehicles or drones can function as distant platforms for mounted sensors, as signal transceivers, or for other purposes. However, they must be tethered. The tether functions as a power cable that connects a tethered drone with a ground power unit. In this article, we developed a concept in which a power cable is of modular structure, consisting of mutually identical modules. Each module has motorised propellers and is capable of preserving itself in a given, hovering position. We formulated an equation for electric current that, for a given set of parameters, makes hovering of a drone with such a modular cable possible. The developed concept does not show significant improvement in maximum height reached by the drone. The underlying causes are extracted from a set of assumptions that define the concept

Toward Parameterisation of E-mail Mediated Communication

E-mail mediated communication rapidly intensifies, both in quantity and quality and so does the need to understand its psycho-social context. In this article we formulated a model of psycho-social elements of the process of receiving an e-mail. The corresponding technique starts by recognising the relevant states of a human receiver and a received e-mail. The states are parameterised, paying special attention to the description of receiver’s emotional states, as the event of receiving is more localised in time than that of sending an e-mail. Possible changes are collected into a vertex, a structure expressing the probability that a received e-mail induces the receiver from initial state into a given final state. We conducted a preliminary study that included 87 e-mail messages. 97 attributes were determined for each of the considered e-mails. The analysis shows that acceptance and total receiver’s change of state induced by e-mails depend on the combination of several e-mail characteristics. These are interpreted as projections of the sender’s states. In this view the e-mail arises as a discrete unit with a finite spectrum of transferable qualities, mediating complex human interaction

Modeling Organizational Design - Applying A Formalism Model From Theoretical Physics

Modern organizations are exposed to diverse external environment influences. Currently accepted concepts of organizational design take into account structure, its interaction with strategy, processes, people, etc. Organization design and planning aims to align this key organizational design variables. At the higher conceptual level, however, completely satisfactory formulation for this alignment doesn’t exist. We develop an approach originating from the application of concepts of theoretical physics to social systems. Under this approach, the allocation of organizational resources is analyzed in terms of social entropy, social free energy and social temperature. This allows us to formalize the dynamic relationship between organizational design variables. In this paper we relate this model to Galbraith\u27s Star Model and we also suggest improvements in the procedure of the complex analytical method in organizational design

Notion of Mediators in Human Interaction

Many types of human interaction are mediated processes. However, regarding the details of human description, the mediating unit structure and dynamics is not developed appropriately. The explicit concentration on mediators contributes to understanding of interplay between value sets governing interaction, interaction roles in regular activities and interaction design for purpose. This article is a contribution to development of a concept of mediated human interaction through structuring of mediated elements. The origin of mediators is the environment, here interpreted as a collection of excitations. Among the excitations, the extracted subgroups are elementary environment excitations (EEE) - which have recognised functions in a local value set, and exchangeable EEEs or mediators - which are used regularly in human interaction. The collection of relations of a human and an EEE is called a vertex. The vertex combines initial and final human states with the EEE. The vertex formally expresses probability that a particular combination of a human state and an EEE brings about a given final human state. Combination of vertices brings about general human-environment and human-human interaction
