...systems-wise, networks of neurons have been the focus of simulation for over 25 years, starting with John Joseph Hopfield’s artificial neural networks (ANNs) in 1982. From that basis, and with many technological revisions, papers in Expert Systems currently present excellent results with ANNs based on a few hundred neurons. But it is still a long way from getting a...

...system responds. Although tiny, viruses are complex, diverse entities that have the capacity to infect hosts, replicate themselves and then spread to additional hosts. In addition, viruses can sometimes transfer between host species, or they can mutate and re-infect the original host species. What is a virus? Viruses are microscopic packages of genetic information (DNA or...

...system is organised, the device in the case of a software controller, or the internet for a web application. The recognised need in Rogers’ definition relates to the problems the software is meant to solve – what we commonly capture as requirements in software development. These problems are the reason why the software should exist, and express how software should...
