This book presents and discusses research in the study of computer science. Topics
discussed include fuzzy logic in molecular computing; mobile database computing; learning
methods for spam filtering; heterogeneous systems; nested relational database systems;
advanced array processing techniques and systems and swarm intelligence.
There exists a worldwide race to make microprocessors of computers as much
powerful as possible by shrinking electronic components and cramming logic gates onto
smaller and smaller wafers of silicon. Over the past few years, some companies and
several academic laboratories have started seriously entertaining the idea of constructing
computers in which computations are performed by individual molecules. If the logic
gates, sculpted from bulk semiconductors, are based exclusively on electrical signals,
those based on single molecules can be extended to chemical, optical and other physical
inputs and outputs. Purpose of the chemist is to find out always-new powerful molecular
systems that can carry out the logic operations required for computer circuitry. If the
compound behaves as a versatile molecular switch, it can be adopted to process Boolean
binary logic. On the other hand, if a chemical species responds to external inputs with a
continuously variable output signal and the relation between inputs and output can be
rationalized in terms of IF-THEN statements, it can be employed to process Fuzzy logic.
Organic compounds exhibiting “Proximity Effect” in their photophysics give an
opportunity to implement Fuzzy logic Engines at the molecular level. For these chemical
species a quantum state, consisting of a superposition of two electronic levels, can be
produced through excitation by UV-Visible radiation. The nature of the quantum state
and its ability to emit light can be varied in a continuous manner by regulating
environmental conditions such as temperature and hydrogen bonding donation ability of
the solvent. This opens up a new avenue to implement Fuzzy logic at the molecular level.
