This paper describes the escape/intervention concept as it is used in the agent growing environment framework. The Escape and Intervention is used in many multi-disciplinary areas, including agent research, artificial intelligence, groupware and workflow, process support, software engineering, and social sciences. Based on an ontological perspective, this paper explains how an interaction-oriented agent architecture and language (used for modelling, simulation, and development) makes use of an interaction pattern that is inspired from social contexts seen as multi-agent systems.

The Irish poet W. B. Yeats once wrote, with great sapience and perception: Nor dread, nor hope attend A dying animal; A man awaits his end Dreading and hoping all. That death has ever been a problem to man is attested as far back as we can trace our species in the archaeological record—indeed, it seems to have been a problem even for that immediate precursor of homo sapiens, the so-called Neanderthal Man; for he buried his dead.

In this unique work, Professor G.A. Powell Jr. writes: "Thinkers are different from writers—writers are prostitutes. Thinkers desire to be prostitutes." Daily Conversations with My Interloper is first and foremost a celebration of the narrative paradigm, its evolution, latitude of expression, and radical subjectivity in the forms of aphorisms and feuilletons. Following in the literary tradition of Ralph Waldo Emerson, Albert Camus, John Cage, Emile Cioran, and Susan Sontag, et al., the text chronicles Professor Powell's reflections about the ongoing metamorphoses (...) of cultures, influential literary figures, travel, film, history, ennui, quotidian, and the mundane day-to-day existence in which all people participate. Daily Conversations with my Interloper, is a provocative read for the public and private intellectual interested in a panoply of ideas. (shrink)

Before talking about national science as a specific phenomenon we find out the essence of science as a phenomenon in general. We note that science is one of the most complex phenomena of social life. Complex understanding of it complicates the fact that science is structurally extremely complex, polyfunctional, historically variable, with many of its faces included in this or that sphere of social life. It therefore appears as an extremely diverse social phenomenon. This raises some difficulties in developing a (...) general definition of it. As G. Volkov correctly pointed out, "there is nothing simpler than giving a definition to any phenomenon, when the whole thing is only in the formulation, and there is nothing more complicated than when it comes to the concentration in the concentrated form of the very essence of the object under study".

In questo volume sono raccolti gli scritti frutto della ricerca effettuata nell’ambito del Progetto: “Ontologia Formale e Ontologie: uno Strumento per il Dialogo Interdisciplinare e Interculturale”. Scopo del progetto è mostrare al pubblico intellettuale italiano, sia di estrazione scientifica che umanistica, le potenzialità dello strumento dell’ontologia in generale, e dell’ontologia formale in particolare, per il dialogo costruttivo interdisciplinare e interculturale. Dialogo interdisciplinare per il rapporto fra discipline scientifiche e umanistiche, dialogo interculturale per il rapporto fra le diverse culture e religioni (...) in una società globalizzata.

The usual representation of quantum algorithms is limited to the process of solving the problem. We extend it to the process of setting the problem. Bob, the problem setter, selects a problem-setting by the initial measurement. Alice, the problem solver, unitarily computes the corresponding solution and reads it by the final measurement. This simple extension creates a new perspective from which to see the quantum algorithm. First, it highlights the relevance of time-symmetric quantum mechanics to quantum computation: the problem-setting and (...) problem solution, in their quantum version, constitute pre- and post-selection, hence the process as a whole is bound to be affected by both boundary conditions. Second, it forces us to enter into relational quantum mechanics. There must be a representation of the quantum algorithm with respect to Bob, and another one with respect to Alice, from whom the outcome of the initial measurement, specifying the setting and thus the solution of the problem, must be concealed. Time-symmetrizing the quantum algorithm to take into account both boundary conditions leaves the representation to Bob unaltered. It shows that the representation to Alice is a sum over histories in each of which she remains shielded from the information coming to her from the initial measurement, not from that coming to her backwards in time from the final measurement. In retrospect, all is as if she knew in advance, before performing her problem-solving action, half of the information that specifies the solution of the problem she will read in the future and could use this information to reach the solution with fewer computation steps. This elucidates the quantum computational speedup in all the quantum algorithms examined. (shrink)

The aim of this article is to offer what I consider to be necessary substantiati for the view that the description of the walk which acts as a frame for the singing contest in Id. 7 is based on a precise knowledge of the geography of t island of Cos and that the poem thus displays a topographical realism unique Greek pastoral.

Le passage de la Lettre à Hérodote consacré au temps (Hrdt. 72-73) est particulièrement obscur. Épicure y affirme explicitement que le mot temps ne renvoie à aucune préconception (prolepse), en tout cas pas au sens habituel qu’a ce terme pour lui, puisqu’il n’existe aucun contenu commun à toutes nos expériences du temps ; et cependant le mot temps n’est pas vide. Cet article vise à résoudre ce paradoxe. Il éclaircit la nature de la perception du temps épicurien et tente de (...) reconstituer le processus cognitif qui la sous-tend. La perception du temps est idiosyncrasique, car elle porte sur une entité de troisième degré : le temps est en effet, selon la formule attribuée à Épicure par Démétrius Lacon, un « accident d’accidents ». Sa perception implique une combinaison d’intuition et de déduction, d’analogie et d’épilogisme, en deçà de la formation d’une préconception – dont nous expliquons l’impossibilité. Elle concerne toujours les durées en tant que nous les rapportons les unes aux autres, selon un « libre jeu » de l’épilogisme et de l’analogie qui ne donne pas lieu à une préconception, mais rend possible de nommer le temps.

This book offers the first comprehensive introduction to wave scattering in nonstationary materials. G. F. Roach's aim is to provide an accessible, self-contained resource for newcomers to this important field of research that has applications across a broad range of areas, including radar, sonar, diagnostics in engineering and manufacturing, geophysical prospecting, and ultrasonic medicine such as sonograms. New methods in recent years have been developed to assess the structure and properties of materials and surfaces. When light, sound, or some other (...) wave energy is directed at the material in question, "imperfections" in the resulting echo can reveal a tremendous amount of valuable diagnostic information. The mathematics behind such analysis is sophisticated and complex. However, while problems involving stationary materials are quite well understood, there is still much to learn about those in which the material is moving or changes over time. These so-called non-autonomous problems are the subject of this fascinating book. Roach develops practical strategies, techniques, and solutions for mathematicians and applied scientists working in or seeking entry into the field of modern scattering theory and its applications. Wave Scattering by Time-Dependent Perturbations is destined to become a classic in this rapidly evolving area of inquiry. (shrink)
