Complex systems

Complex systems
Complex systems present problems both in mathematical modelling and philosophical foundations. The study of complex systems represents a new approach to science that investigates how relationships between parts give rise to the collective behaviors of a system and how the system interacts and forms relationships with its environment.[1] Such systems are used to model processes in computer science, biology,[2] economics, physics, chemistry,[3] and many other fields. It is also called complex systems theory, complexity science, study of complex systems, sciences of complexity, non-equilibrium physics, and historical physics. A variety of abstract theoretical complex systems is studied as a field of mathematics. The key problems of complex systems are difficulties with their formal modelling and simulation.

Chaos Theory: A Brief Introduction What exactly is chaos? The name "chaos theory" comes from the fact that the systems that the theory describes are apparently disordered, but chaos theory is really about finding the underlying order in apparently random data. When was chaos first discovered? The first true experimenter in chaos was a meteorologist, named Edward Lorenz. In 1960, he was working on the problem of weather prediction. He had a computer set up, with a set of twelve equations to model the weather.

Self-organization Self-organization occurs in a variety of physical, chemical, biological, robotic, social and cognitive systems. Common examples include crystallization, the emergence of convection patterns in a liquid heated from below, chemical oscillators, swarming in groups of animals, and the way neural networks learn to recognize complex patterns. Overview[edit] The most robust and unambiguous examples[1] of self-organizing systems are from the physics of non-equilibrium processes. Self-organization is also relevant in chemistry, where it has often been taken as being synonymous with self-assembly. The concept of self-organization is central to the description of biological systems, from the subcellular to the ecosystem level.

Francis Heylighen Francis Paul Heylighen (born 1960) is a Belgian cyberneticist investigating the emergence and evolution of intelligent organization. He presently works as a research professor at the Vrije Universiteit Brussel, the Dutch-speaking Free University of Brussels, where he directs the transdisciplinary research group on "Evolution, Complexity and Cognition"[1][2] and the Global Brain Institute. He is best known for his work on the Principia Cybernetica Project, his model of the Internet as a Global brain, and his contributions to the theories of memetics and self-organization. Biography[edit] Francis Heylighen was born on September 27, 1960 in Vilvoorde, Belgium. He received his high school education from the "Koninklijk Atheneum Pitzemburg" in Mechelen, in the section Latin-Mathematics.

Carnegie Science Center: 21+ Night 6 – 10 pm All those who have ever wanted to enjoy Carnegie Science Center without having to elbow 8-year-olds out of the way for a chance to compete against the Air Hockeybot or launch a rocket into the air, will not want to miss 21+ Night at Carnegie Science Center. Highmark Sportsworks® and the USS Requin Submarine will not be open for the evening. 21+ Gaming June 19, 2015 Complex adaptive system They are complex in that they are dynamic networks of interactions, and their relationships are not aggregations of the individual static entities. They are adaptive in that the individual and collective behavior mutate and self-organize corresponding to the change-initiating micro-event or collection of events.[1][2] Overview[edit] The term complex adaptive systems, or complexity science, is often used to describe the loosely organized academic field that has grown up around the study of such systems.

Complex Adaptive Systems: 9 Cellular Automaton + Related Videos - Mashpedia In this video we are going to discuss cellular automata, we will firstly talk about what they are before looking at a classical example, we will then discuss individually the different classes of patterns that cellular automata can generate before wrapping-up with a talk about their significance as a new approach to mathematical modeling. For full courses, transcriptions & downloads please see: Twitter: Facebook: Transcription Excerpt: Cellular automata are algorithmic models that use computation to iterate on very simple rules, in so doing these very simple rules can create complex emergent phenomena through the interaction between agents as they evolve over time. To illustrate the functioning of a cellular automaton we will take an example from probably the most famous algorithm called the Game Of Life devised by the mathematician John Conway. The Game Of Life is played on a grid of square cells.

By Katie Booth, Gideon Bradshaw, Sean Collier, Lauren Davidson, Eric Lidji, Kristina Martin, Mike May and Amy Whipple (page 1 of 4) Best Place to Waffle Over Your Breakfast Selection Austrian School The Austrian School is a school of economic thought that is based on methodological individualism.[1][2][3][4] It originated in late-19th and early-20th century Vienna with the work of Carl Menger, Eugen von Böhm-Bawerk, Friedrich von Wieser, and others.[5] Current-day economists working in this tradition are located in many different countries, but their work is referred to as Austrian economics. Among the theoretical contributions of the early years of the Austrian School are the subjective theory of value, marginalism in price theory, and the formulation of the economic calculation problem, each of which has become an accepted part of mainstream economics.[6] Many economists are critical of the current-day Austrian School and consider its rejection of econometrics and aggregate macroeconomic analysis to be outside of mainstream economic theory, or "heterodox.

Audio time-scale/pitch modification - Wikipedia These processes are used, for instance, to match the pitches and tempos of two pre-recorded clips for mixing when the clips cannot be reperformed or resampled. (A drum track containing no pitched instruments could be moderately resampled for tempo without adverse effects, but a pitched track could not). They are also used to create effects such as increasing the range of an instrument (like pitch shifting a guitar down an octave).

Behavioral economics There are three prevalent themes in behavioral finances:[3] Issues in behavioral economics[edit] Behavioral finance[edit] article This article was first published in Software Developer's Journal 4/2006 and SDJ Extra 4/2006 Magazines by Software Wydawnictwo. Article reprinted online by original author in courtesy of Software Developer's Journal. Available also in German as Audio-Zeit-und-Pitch-Skalierung. by Olli Parviainen Introduction Anyone who's used a nowadays obsolete tape recorder or a vinyl disc player is likely familiar with effects of playing the recording back at different speed than it was originally recorded: Playing the recording at double speed reduces the playtime to half, at the same time causing a side-effect of the sound pitch jumping up by an octave which amusingly converts human voices to sound like cartoon figures.
