PageRank (PR) is used by web search engine Google in ranking individual web pages. However, it is known that this value is also easily manipulated by methods known as spoofing. Further, the calculation of PR will require iterative cycles of computations to achieve a “steady” value. This would mean t.....

Ultra-precision freeform surfaces are important to the development of complex and micro-optical-electro-mechanical devices used in many photonics and telecommunication products such as F-theta lenses for laser printers. These surfaces are complex and large scale surface topologies with shapes that g.....

A digital communication system based on the use of chaotic carriers is disclosed. For each symbol to be sent, the transmitter sends a reference chaotic signal followed by a transformed version of the reference chaotic signal. For different symbols, different transformations are performed. Also, the .....

Polypyrrole (PPy) is one of the most commonly studied conducting polymers due to its good stability, high conductivity, ease of preparation and non-toxicity. The stability of the conductivity of polypyrrole films depends on the choice of dopant anion, the method of preparation, and the conditions of.....
