QCM Hardware Technology for Edge Computing

For applications requiring ultra-fast on-board monitoring of critical components, systems or infrastructures, Ontonix offers a Complexity And Health Monitoring System (CAHMS) – a device that can be mounted on cars, aircraft, submarines, helicopters or missiles or on any mission-critical equipment and deliver early warning signals of imminent systemic malfunctions. The CAHMS can be interfaced to a

A Survey of “Complexity Measures”,,,,, Without Measures

We report verbatim a 1998 article A Survey of “Complexity Measures” by David P. Feldman and Jim Crutchfield.

A more adequate title for this evasive article would be “A Survey of How Science Avoids to Measure Complexity”. Once you’ve read it, ask yourself this: can I use any of these measures to actually measure the complexity of, say,

a piece of equipment, e.g. an electromechanical system

an…

Cellular Automatons and Complexity

From the Wikipedia: A cellular automaton is a discrete model studied in computability theory, mathematics, physics, complexity science, theoretical biology and microstructure modelling. It consists of a regular grid of cells, each in one of a finite number of states, such as “On” and “Off” (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions.

For each…

Complexity and How Serious Science Starts When You Begin to Measure

Network with growing number of nodes, edges and complexity. Contemporary “complexity science” is unable to measure its complexity. Surprisingly it doesn’t even try.

Not everything that counts can be measured and not everything that can be measured counts. This variation of a quote by Einstein is often used as an excuse in order to confine things that may be quantified into the realm…

QCM – What it is NOT

Quantitative Complexity Management (QCM) technology has been around since 2005. It is a very unusual piece of technology and offers a radically innovative approach to dealing with data, anomalies and risk. As it happens with innovative technologies, they are often years ahead of mainstream thought, sometimes even ahead of predominant and accepted philosophies. And herein lies the problem. If you…

What are the Units of Complexity?

Complexity is a fundamental physical characteristic of every system that may be found in Nature. Its importance is similar to that of energy. There have been numerous attempts of measuring complexity. However, most are limited either to very simple systems, character strings or to computer code and have very little practical use. In many cases, measures of complexity have been equated to…
