Influence of Artificial Intelligence on Communication Systems

Influence of Artificial Intelligence on Communication Systems

An invited talk at Snow & Avalanche Study Establishment Research & Development Center (SASE RDC), Chandigarh, on April 16, 2008, by R C Chakraborty, Visiting Prof. JIET, Guna & Former Dir. DTRL & ISSA (DRDO). The Highlights of my talk :

(a) Timeline of Telecommunication related technology – Telegraph, Morse code, Telephone Exchange, Wireless telegraphy, Iconoscope, Television system, Radio networks;

(b) Timeline of Artificial Intelligence related technology – Roman Abacus, Pascaline, Diff. Engine, Boolean algebra, Turing machines, Von Neumann architecture, ENIAC;

(c) Timeline of AI events – Turing test, intelligent behavior, Logic Theorist, Birth of AI, General Problem Solver, LISP language, DoD’s Advanced Research projects, Micro-world program SHRDLU, Expert systems, Computer vision, Prolog ;

(d) Modern digital communications – geosynchronous communication satellites, packet switching theory, wide-area computer network, Optical fiber, Internet era, ARPANET, Birth of login – ‘log’ ‘in’, Protocol – TCP/IP, Internet;

(e) AI vocabulary – Intelligence, Intelligent behavior, knowledge is collection of facts, Learning is what facts or behaviors represent, Knowledge Model – a degree of connectedness & understanding that increase, we progress from data to information to knowledge and to wisdom;

(f) Building Intelligent Communication Systems – Seamless global network, Intelligent mobile platform, Voice-recognition across Mobile-phone, and Knowledge base Networking;

(g) Conclusion – We live in an era of rapid change, moving from information to knowledge based seamless global intelligent network of society.  The creation of intelligence in machine has been a long cherished desire to replicate the functionality of the human mind. Intelligent information and communications technology (IICT), emulates and employ some aspect of human intelligence in performing a task. The IICT based systems, include sensors, computers, knowledge-based software, human-machine interfaces and other devices. Today, intelligent systems applications exists virtually in all sectors where they deliver social as well as economic benefits.

Electromagnetic Pollution Causing Health Hazards

Electromagnetic Pollution Causing Health Hazards. How do you campaign to resolve issues?

Information about health is fundamental to saving lives. Electromagnetic fields (EMFs) emanate from radar, broadcast transmission towers, microwave ovens, cellular phones, wireless local area networks (WLANs), power lines (50/60 Hz) and many other sources. Information about environmental influences of Electromagnetic fields are causing anxiety among general populations. All populations, where ever they are, now exposed to varying degrees of EMF. The exposure to EMF will continue to increase as technology advances. During the past 20 years the general public has become increasingly concerned about adverse health effects of exposure to electric and magnetic fields. They are unable to get any satisfying answer about the EM fields causing health hazards. The potential health effects of exposure to static and time varying electric and magnetic fields need unambiguous scientific clarification. Even a small health consequence from EMF exposure could have a major public health impact. To protect public health and to answer the public perception of risk, the World Health Organization (WHO) established “International EMF Project” in 1996 (Ref. The EMF Project encourages focused research to evaluate health issues raised because of exposure to electromagnetic fields (EMF) in the frequency range from 0 to 300 GHz. However, the research results are often contradictory, creating confusion, breaking confidence and building more public concern. So the question remains How do you campaign to resolve issues ? “.
