This book was released on 2021-04-12 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present-day power grid is basically a complex power transmission network with risks of failure due to unplanned attacks and contingencies, and therefore, assessment of vulnerability of transmission network is important and the process is based on contingency approach. This book deals with the methods of assessment of the grid network vulnerability and addresses the grid collapse problem due to cascaded failures of the transmission network following an attack or an unplanned contingency. Basic mitigation aspects for the network has been explored and the immunity of such a power transmission network against vulnerable collapse has been described using mathematical models.

Available in PDF, EPUB and Kindle. Book excerpt: The subject “Systems sciences and cybernetics” is the outcome of the convergence of a number of trends in a larger current of thought devoted to the growing complexity of (primarily social) objects and arising in response to the need for globalized treatment of such objects. This has been magnified by the proliferation and publication of all manner of quantitative scientific data on such objects, advances in the theories on their inter-relations, the enormous computational capacity provided by IT hardware and software and the critical revisiting of subject-object interaction, not to mention the urgent need to control the efficiency of complex systems, where “efficiency” is understood to mean the ability to find a solution to many social problems, including those posed on a planetary scale. The result has been the forging of a new, academically consolidated scientific trend going by the name of Systems Theory and Cybernetics, with a comprehensive, multi-disciplinary focus and therefore apt for understanding realities still regarded to be inescapably chaotic. This subject entry is subdivided into four sections. The first, an introduction to systemic theories, addresses the historic development of the most commonly used systemic approaches, from new concepts such as the so-called “geometry of thinking” or the systemic treatment of “non-systemic identities” to the taxonomic, entropic, axiological and ethical problems deriving from a general “systemic-cybernetic” conceit. Hence, the focus in this section is on the historic and philosophical aspects of the subject. Moreover, it may be asserted today that, beyond a shadow of a doubt, problems, in particular problems deriving from human interaction but in general any problem regardless of its nature, must be posed from a systemic perspective, for otherwise the obstacles to their solution are insurmountable. Reaching such a perspective requires taking at least the following well-known steps: a) statement of the problem from the determinant variables or phenomena; b) adoption of theoretical models showing the interrelationships among such variables; c) use of the maximum amount of – wherever possible quantitative – information available on each; d) placement of the set of variables in an environment that inevitably pre-determines the problem. That epistemology would explain the substantial development of the systemic-cybernetic approach in recent decades. The articles in the second section deal in particular with the different methodological approaches developed when confronting real problems, from issues that affect humanity as a whole to minor but specific questions arising in human organizations. Certain sub-themes are discussed by the various authors – always from a didactic vantage –, including: problem discovery and diagnosis and development of the respective critical theory; the design of ad hoc strategies and methodologies; the implementation of both qualitative (soft system methodologies) and formal and quantitative (such as the “General System Problem Solver” or the “axiological-operational” perspective) approaches; cross-disciplinary integration; and suitable methods for broaching psychological, cultural and socio-political dynamisms. The third section is devoted to cybernetics in the present dual meaning of the term: on the one hand, control of the effectiveness of communication and actions, and on the other, the processes of self-production of knowledge through reflection and the relationship between the observing subject and the observed object when the latter is also observer and the former observed. Known as “second order cybernetics”, this provides an avenue for rethinking the validity of knowledge, such as for instance when viewed through what is known as “bipolar feedback”: processes through which interactions create novelty, complexity and diversity. Finally, the fourth section centres around artificial and computational intelligence, addressing sub-themes such as “neural networks”, the “simulated annealing” that ranges from statistical thermodynamics to combinatory problem-solving, such as in the explanation of the role of adaptive systems, or when discussing the relationship between biological and computational intelligence.

Available in PDF, EPUB and Kindle. Book excerpt: Why is the question of the di?erence between living and non-living matter - tellectually so attractive to the man of the West? Where are our dreams about our own ability to understand this di?erence and to overcome it using the ?rmly established technologies rooted? Where are, for instance, the cultural roots of the enterprises covered nowadays by the discipline of Arti?cial Life? Cont- plating such questions, one of us has recognized [6] the existence of the eternal dream of the man of the West expressed, for example, in the Old Testament as follows: . . . the Lord God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being (Genesis, 2. 7). This is the dream about the workmanlike act of the creation of Adam from clay, about the creation of life from something non-living, and the con?dence in the magic power of technologies. How has this dream developed and been converted into a reality, and how does it determine our present-day activities in science and technology? What is this con?dence rooted in? Then God said: “Let us make man in our image. . . ” (Genesis, 1. 26). Man believes in his own ability to repeat the Creator’s acts, to change ideas into real things, because he believes he is godlike. This con?dence is – using the trendy Dawkins’ term – perhaps the most important cultural meme of the West.

Book excerpt: En los sistemas complejos, cada problema, debe ser tratado en detalle partiendo de cero, y poco o nada de lo aprendido al resolver un sistema anterior nos puede ayudar a entender uno nuevo. En los sistemas caóticos, de dos condiciones iniciales ligeramente distintas se obtienen, en el tiempo, dos soluciones dramáticamente diferentes. Casi todos los sistemas reales son termodinámicamente abiertos, mientras que los sistemas aislados, fuera de ser considerados sólo teóricamente, son raros en la naturaleza. La naturaleza sigue el principio del orden a partir del caos o desorden, contrario diametralmente al que estipula la física clásica, que va del orden al desorden, La visión del mundo de los sistemas complejos exige una nueva forma de hacer ciencia. La complejidad, un travestista del enfoque ético sistémico, intenta dar solución a problemas considerados como críticos, y crítico es todo lo que desconocemos, y para acceder a lo desconocido, según las reglas actuales, se reclama un episentido.

Book excerpt: En un mundo de extrema saturación, lo que salta a la primera página es algo más que la diferenciación, es la diferenciación radical que tiene que ver con encontrar un espacio de mercado totalmente nuevo del que puedas apropiarte y defenderlo, obteniendo beneficios durante años en lugar de meses. Hacer zag cuando todos hacen zig. Esa es la clave para sobrevivir en una época en la que proliferan los productos de imitación, hay un exceso de oferta y los consumidores y no las empresas son quienes deciden qué marcas sobreviven y cuáles no.

Download or read book El inter s en la vida written by Luis Chiozza and published by Libros del Zorzal. This book was released on 2020 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: El rótulo que define la línea argumental que el autor recorre en este libro, es el que corresponde al subtítulo: Sólo se puede ser, siendo con otros. La suficiencia o el déficit de ese ser con los otros, define la magnitud que alcanza la cualidad fundamental que el título designa: El interés en la vida. Se trata de inter-essere, de ser “entre” otros, y en esa ineludible realidad de la vida, que ocurrirá bien o mal, pero que inevitablemente ocurre, reside la forma buena o mala en que nos alcanzarán la cosas de la vida, aquellas que, sin poderlo evitar, nos importaron, nos importan, y nos importarán, siempre, mucho más de lo que a veces preferimos creer. Los capítulos de este volumen intentan mostrar, casi esquemáticamente, centrándose en las ramas, y dejando el follaje, que escapa a las posibilidades de un libro singular, no sólo las distintas vicisitudes, sino también las circunstancias del mundo en que vivimos, que nos conducen hacia las formas habituales en que la ineludible condición de ser entre otros, conviviendo, ingresa a veces en pesadumbres y carencias que son típicas de las épocas que una vida recorre. Contemplar desde ese ángulo las pesadumbres y carencias que suelen colocarnos “en los umbrales de la enfermedad”, no sólo nos ilumina “desde el alma” lo que muchas veces sucede en el cuerpo, también nos permite comprender cómo el alma se “conforma”, mejor o peor, resonando a su manera con el espíritu que impregna su entorno.

Book excerpt: Aunque la realidad es mucho más profunda. El potencial cuántico es lo que permite la interconexión y forma el sistema en el que se desenvuelve toda la situación conjunta. A partir de experimentos constatados en el subterfugio de las partículas elementales, se concluye tajantemente, que todo se halla interrelacionado con todo, que no hay nada separado de nada, que la filosofía nunca concluirá nada, y que todo lo que percibimos, más allá de lo que nos hagan creer nuestros sentidos y nuestra mente, no es sino la forma o expresión que nos remite a una realidad primordial que algunos no dudan en nombrar como conciencia. Una conciencia que se origina en el único cerebro que la naturaleza nos suministró con carencias, un gigantesco resorte que absorbe y disipa energía, y vibra en su propia frecuencia de ineficiencia, y para su completamiento, precisa con urgencia la intervención de la ciencia, que es la única que puede proveerlo, extranatura, de un episentido.

Available in PDF, EPUB and Kindle. Book excerpt: Desde la perspectiva sociológica, el concepto de tecnología no puede referirse únicamente a los objetos técnicos, sino también a los procesos sociales y culturales que involucra. La sociocibernética y la teoría de sistemas plantean un marco conceptual esencial para el necesario debate sobre el papel de la tecnología en la configuración de la complejidad social. La tecnología permite al sistema social gestionar la complejidad social. La tecnología permite al sistema social gestionar la complejidad de su entorno a la vez que, por otra parte, contribuye a incrementar y diversificar la naturaleza compleja de las interdependencias entre la sociedad y los actores individuales. Simultáneamente, la creciente complejidad social demanda nuevas formas tecnológicas que permitan gestionarla. En suma, la tecnología se halla en la base de cualquier discusión relevante sobre la naturaleza contemporánea de la sociedad, ya sea del lado de los problemas (riesgo, control, y vigilancia global, bioética y bioingeniería, manipulación mediática, ecológica etc.) o del lado de las soluciones (comunicaciones instantáneas, ubicuidad y movilidad, accesibilidad, disponibilidad de conocimiento, etc.).
