Abstract

Fractal analysis has entered a new era. The applications to different areas of knowledge have been surprising. Let us begin with the fractional calculus-fractal geometry relationship, which allows for modeling with extreme precision of phenomena such as diffusion in porous media with fractional partial differential equations in fractal objects. Where the order of the equation is the same as the fractal dimension, this allows us to make calculations with enormous precision in diffusion phenomena-particularly in the oil industry, for new spillage prevention. Main applications to industry, design of fractal antennas to receive all frequencies and that is used in all cell phones, spacecraft, radars, image processing, measure, porosity, turbulence, scattering theory. Benoit Mandelbrot, creator of fractal geometry, would have been surprised by the use of fractal analysis presented in this book: ""Part I: Petroleum Industry and Numerical Analysis""; ""Part II: Fractal Antennas, Spacecraft, Radars, Image Processing, and Measure""; and ""Part III: Scattering Theory, Porosity, and Turbulence."" It's impossible to picture today's research without fractal analysis.

Abstract

Modeling and simulating biological and physical systems are nowadays active branches of science. The diversity and complexity of behaviors and patterns present in the natural world have their reciprocity in life systems. Bifurcations, solitons and fractals are some of these ubiquitous structures that can be indistinctively identified in many models with the most diverse applications, from microtubules with an essential role in the maintenance and the shaping of cells, to the nano/microscale structure in disordered systems determined with small-angle scattering techniques. This book collects several works in this direction, giving an overview of some models and theories, which are useful for the study and analysis of complex biological and physical systems. It can provide a good guidance for physicists with interest in biology, applied research scientists and postgraduate students.

Abstract

The aim of this book is to show some applications of fractal analysis in the fields of sciences. The first chapter introduces the readers to the book, while the second chapter shows the methods and challenges of fractal analysis of time-series data sets. The third chapter demonstrates fractal geometry as an attractive choice for miniaturized planar microwave filter design. The fourth chapter presents fractal antennas for wearable applications. The objective of the fifth chapter is to show some Parrondian games in discrete dynamic systems, while the last chapter reveals fractal structures of carbon nanotube system arrays.

Abstract

Diese Studie wirft die Frage auf, inwieweit eine Pädagogik jenseits der Erstarrung in systemischen Strukturen beweglich und systematisch zu denken ist. Dieser paradoxen Ausgangskonstellation kann mit der späten Systemtheorie Luhmanns begegnet werden, die den Versuch unternimmt, eine differentialistische Wende jenseits des klassischen Differenzbegriffes voranzutreiben. Die bislang offenen Enden dieses Projekts werden mit Deleuze weiterentwickelt. In einer topologischen Lesart - insbesondere aus dem Blickwinkel einer Topologie der Differenz - kann Pädagogik so als Ausdruckssystem refiguriert werden.

Abstract

An important amount of research effort in psychology and neuroscience over the past decades has focused on the problem of social cognition. This problem is understood as how we figure out other minds, relying only on indirect manifestations of other people's intentional states, which are assumed to be hidden, private and internal. Research on this question has mostly investigated how individual cognitive mechanisms achieve this task. A shift in the internalist assumptions regarding intentional states has expanded the research focus with hypotheses that explore the role of interactive phenomena and interpersonal histories and their implications for understanding individual cognitive processes. This interactive expansion of the conceptual and methodological toolkit for investigating social cognition, we now propose, can be followed by an expansion into wider and deeply-related research questions, beyond (but including) that of social cognition narrowly construed. Our social lives are populated by different kinds of cognitive and affective phenomena that are related to but not exhausted by the question of how we figure out other minds. These phenomena include acting and perceiving together, verbal and non-verbal engagement, experiences of (dis-)connection, management of relations in a group, joint meaning-making, intimacy, trust, conflict, negotiation, asymmetric relations, material mediation of social interaction, collective action, contextual engagement with socio-cultural norms, structures and roles, etc. These phenomena are often characterized by a strong participation by the cognitive agent in contrast with the spectatorial stance typical of social cognition research. We use the broader notion of embodied intersubjectivity to refer to this wider set of phenomena. This Research Topic aims to investigate relations between these different issues, to help lay strong foundations for a science of intersubjectivity – the social mind writ large. To contribute to this goal, we encouraged contributions in psychology, neuroscience, psychopathology, philosophy, and cognitive science that address this wider scope of intersubjectivity by extending the range of explanatory factors from purely individual to interactive, from observational to participatory.

Abstract

Der Zerfall der sowjetischen Organisationsgesellschaft hat vielfältige Veränderungen in Gang gesetzt. Evelyn Moser perspektiviert diese Veränderungen mithilfe der Differenzierungstheorie und der Theorie der Weltgesellschaft. Auf der Grundlage ethnographischer Feldforschung untersucht sie die Umstellungen und Neuordnungen, die sich im Kontext von politischer Dezentralisierung und landwirtschaftlicher Privatisierung vollziehen und die Transformationsgesellschaft im ländlichen Russland kennzeichnen. Zu beobachten ist lokale Kontingenz im Horizont der Weltgesellschaft: Änderungsabsichten müssen Engpässe passieren, Normalitätserwartungen verschieben sich und neue Anschlussmöglichkeiten entstehen.

Abstract

Alle reden von Netzen und Netzwerken. Was bislang in der Medienwissenschaft fehlt, ist eine empirisch belastbare und theoretisch hinreichend komplexe Theorie der Fäden, Knoten, Netze und Netzwerke. Der Medienepistemologe Stefan Weber stellt sich mit diesem Buch dieser Aufgabe. Ist das Internet ein Medium oder bloß technische Infrastruktur? Ist das World-Wide-Web ein autopoietisches System? Sind Netzwerke Systeme? - Fragen dieser Art beherrschen die netzwissenschaftliche Debatte und zeugen von begrifflichen Konfusionen angesichts der neuen Medien. Webers Text ist der Versuch einer Flurbereinigung. Empirisch führt der Theorievorschlag zu einer strukturierten Beobachtung von Mikro- bis Makro-Trends der Netzmedialisierung: 'Viralisierung', Selbstreferenzialisierung, Mensch/Maschine-Entdifferenzierung, Entdualisierung klassischer Kommunikationsverhältnisse und Redualisierung binärer Sozialstrukturen.

Abstract

Es ist kein Geheimnis, daß das, was wir so alltäglich Person, Bewußtsein, Psyche, Individuum etc. nennen, in den avancierten Theorien der Soziologie und der Philosophie zu verdunsten scheint. Immer deutlicher wird, daß das Bewußtsein, dem die Tradition einen Eigenwert zugeschrieben hatte, überformt wird durch soziale Prozesse. Es kann sich nicht selbst beobachten, ohne sich als individuelle Allgemeinheit zu entdecken. Der instruktive Essay von Peter Fuchs setzt sich mit diesem Problem auseinander. Er erkundet das Terrain der Bewußtseinsfrage - im Zusammenhang mit wichtigen Anrainerbegriffen wie eben Person, Psyche, Individuum - auf dem Niveau und mit den Mitteln der Systemtheorie, also einer der Theorien, die den Eigenwert des Bewußtseins massiv zu bedrohen scheinen. Der Begriff der individuellen Signatur und ihrer Gegenzeichnung wird in aller Vorläufigkeit herangezogen, um den Raum der Diskussion des Problems zu öffnen.

Abstract

Modern science is defined on one hand as an autotelic pursuit of truth. On the other hand, it also keeps the practical benefit of new knowledge in its sights. David Kaldewey reconstructs the origin and significance of this dual goal by means of historical-sociological semantic analysis. He shows how both objectives condense among a variety of autonomy and practice discourses. The tension between these discourses reveals itself from a differentiation theoretical perspective as constitutive of the dynamics of modern science.
