Zachman Framework The Zachman Framework of enterprise architecture The Zachman Framework is not a methodology in that it does not imply any specific method or process for collecting, managing, or using the information that it describes.; rather, it is an Ontology whereby a schema for organizing architectural artifacts (in other words, design documents, specifications, and models) is used to take into account both whom the artifact targets (for example, business owner and builder) and what particular issue (for example, data and functionality) is being addressed. The framework is named after its creator John Zachman, who first developed the concept in the 1980s at IBM. It has been updated several times since. Overview The term "Zachman Framework" has multiple meanings. Collage of Zachman Frameworks as presented in several books on Enterprise Architecture from 1997 to 2005. The framework is a logical structure for classifying and organizing the descriptive representations of an enterprise.
What is Emergent Thinking? | David Brooks With rendition switcher David Brooks: Carl Popper, the great philosopher said, “All problems are either clouds or clocks.” A clock is a… to understand a clock, you can take it apart, it’s individual pieces and you study the pieces and then you can understand how a clock works. So an emergent system is something you only can study as a whole. So we’re surrounded by these patterns of interaction, these emergent systems. And so when you talk about a corporate culture or a marketplace or anything, it’s about the complex interplay of all these different things.
Introduction to Complex Systems by David Kirshbaum I. Introduction: Complex Systems Theory : Basic Definition II. Four Important Characteristics of Complexity: III. I. A Complex System is any system which involves a number of elements, arranged in structure(s) which can exist on many scales. Previously, when studying a subject, researchers tended to use a reductionist approach which attempted to summarize the dynamics, processes, and change that occurred in terms of lowest common denominators and the simplest, yet most widely provable and applicable elegant explanations. But since the advent of powerful computers which can handle huge amounts of data, researchers can now study the complexity of factors involved in a subject and see what insights that complexity yields without simplification or reduction. Scientists are finding that complexity itself is often characterized by a number of important characteristics: (II.1) Self-Organization(II.2) Non-Linearity(II.3) Order/Chaos Dynamic(II.4) Emergent Properties.

Lynn Margulis and Dorion Sagan - Microbial Microcosm Just how interconnected are we? The work of biologist Lynn Margulis and writer Dorion Sagan indicates we’re interconnected in ways few of us have probably ever considered. In fact, instead of viewing ourselves as the pinnacle of evolution, it may be more accurate to think of ourselves as a colony of closely associated bacteria. Carla Cole based the following on the work of Lynn Margulis and Dorion Sagan, including an article of theirs, The Parts: Power to the Protoctists, which appeared in the September/October 1992 issue of Earthwatch. All life on Earth today derived from common ancestors. Far from leaving microorganisms behind on an evolutionary ladder, we more complex creatures are both surrounded by them and composed of them. In the first two billion years of life on Earth, bacteria – the only inhabitants – continuously transformed the planet’s surface and atmosphere and invented all life’s essential, miniaturized chemical systems.
Underground ant city in Brazil that 'rivals the Great Wall of China' with a labyrinth of highways By Julian Gavaghan Updated: 16:51 GMT, 2 February 2012 A sophisticated underground ant city once populated by millions of insects has been discovered by a team of scientists. The abandoned megalopolis, which features vast subterranean highways, paths and gardens, was found buried beneath the earth in Brazil. It is thought to have housed one of the biggest ant colonies in the world. But no one is sure when the leafcutter species left and what caused their demise. Scroll down to watch the amazing video Underground city: The network of tunnels and dens built by millions of Leaf Cutter ants in Brazil Experts poured ten tonnes of concrete into holes on the surface – which served as air conditioning ducts for the ants – to expose the tunnels by solidifying in the space. It took ten days to pour the material down the labyrinth of channels, which covered an area of 500sq ft and extended to 26ft below the surface.. Vast: The Leaf Cutters are said to form the second most complex society after our own
Pattern recognition Pattern recognition algorithms generally aim to provide a reasonable answer for all possible inputs and to perform "most likely" matching of the inputs, taking into account their statistical variation. This is opposed to pattern matching algorithms, which look for exact matches in the input with pre-existing patterns. A common example of a pattern-matching algorithm is regular expression matching, which looks for patterns of a given sort in textual data and is included in the search capabilities of many text editors and word processors. Pattern recognition is studied in many fields, including psychology, psychiatry, ethology, cognitive science, traffic flow and computer science. Overview Pattern recognition is generally categorized according to the type of learning procedure used to generate the output value. Note that sometimes different terms are used to describe the corresponding supervised and unsupervised learning procedures for the same type of output. . to output labels . .
Mimivirus Mimivirus is a viral genus containing a single identified species named Acanthamoeba polyphaga mimivirus (APMV). It also refers to a group of phylogenetically related large viruses, designated usually "MimiN." In colloquial speech, APMV is more commonly referred to as just "mimivirus." Mimivirus has a large and complex genome compared with most other viruses. Discovery The same team that discovered the mimivirus later discovered a slightly larger virus, dubbed the mamavirus, and the Sputnik virophage that infects it. Classification Mimivirus has been placed into a viral family by the International Committee on Taxonomy of Viruses as a member of the Mimiviridae, and has been placed into Group I of the Baltimore classification system. Although not strictly a method of classification, Mimivirus joins a group of large viruses known as nucleocytoplasmic large DNA viruses (NCLDV).

iecps Institute of Studies of Complexity and Systems Thinking Vladimir Dimitrov IntroductionChaos and Complexity theory studies nonlinear processes: Chaos explores how complexly interwoven patterns of behaviour can emerge out of relatively simply-to-describe nonlinear dynamics, while Complexity tries to understand how relatively simply-to-describe patterns can emerge out of complexly interwoven dynamics. Both Chaos and Complexity build the core of Complexity Science actively promoted in the research publications of the Santa Fe Institute in USA established in 1984. A Historical OutlookChaos and Complexity emerge from non-linear mathematics. With their pioneering works on local stability (instability) of dynamical systems in the last decade of the 19 century, the Russian mathematicians Andrey Lyapunov and Sophia Kovalevskaya are viewed as the founders of the single and most creative and prolific stand of thought in the analysis of dynamic discontinuities and non-linearities up to the present day, the Russian School.

untitled Thanks for your interest in Copycat! Copycat is written in Common Lisp. The system is unfortunately rather outdated: it will not run as is without some updates for modern versions of Common Lisp, and some platform-specific modifications to the graphics files. I am hoping that it will be rewritten in a more platform independent way sometime soon. I am still making the source files available. To get the source files, go to : and at your home machine, untar the file to get the source files. If your system can't deal with tar files, then go to and individually get each source file. To get Jim Marshall's Metacat project, go to: Scott Bolland of the University of Queensland wrote a Java version of Copycat and a tutorial; the web site is
