Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart). From:…
When we make decisions or when we think our brain does not use any equations or math models. Our behaviour is fruit of certain hard-wired instincts and experience that is acquired during our lives and stored as patterns (or attractors). We sort of “feel the answer” to problems no matter how complex they may seem…
Models are simplified representations or emulators of reality. They are typically based on empirical data collected conducting experiments. There exist numerous techniques for establishing models based on data. An example of a linear model, built based on 2-dimensional data is illustrated below. The model in this simple case is a straight line. It may be…
Anomaly detection, especially their early detection, is a crucial capability when it comes to operating large complex systems, processes or critical infrastructures. Because it is difficult to make highly complex systems resilient in the face of a multitude of potential often unknown hazards, it is desirable to be able to identify anomalies, malfunctions and attacks…
Comment to our previous blog: Ontonix is launching a huge change and I love changes. Things that do not change scare me, because they look too much like death. However, for years we have been looking for resilience, we have been defining resilience, we have been measuring resilience, we have been preaching resilience. Are we…
Resilience is a fancy, fashionable à la mode word. Being able to withstand the slings and arrows of outrageous fortune is something everyone wants. The ability to recover quickly, to spring back into the original shape is certainly desireable in any field. Nature builds resilient things. Engineers are sometimes able to create resilient designs. This…
OntoView™ is a real-time monitoring system which processes live video images. The program analyzes the complexity of the captured live image content and alerts of traffic problems in real time. The revolutionary aspect of OntoView™ is that it doesn’t analyze images based on conventional image-processing techniques. Instead, it emulates the way the brain perceives images,…
Every year the World Bank publishes its Development Indicators data, which we analyze in order to measure and track the resilience (fragility) and complexity of countries, macro regions and of the world as a system. The goal is to produce strategic systemic information for governments and government agencies especially in the context of management of disasters,…
Each year the World Bank publishes its Development Indicators data, which we analyze in order to measure and track the resilience and complexity of countries, macro regions and of the world as a system. The goal is to extract strategic and systemic information which may be useful to governments and government agencies especially in the…
In highly complex contexts, or when one runs out of arguments in a debate, it is customary to resort to elaborate conspiratory theories. Theories are constructed based on a set of data points. When many data points are available, one can construct many theories. The problem is that all these theories will agree in the…
