As everybody is undoubtedly aware, we are living in the midst of rapid information renovation and
innovation. The changing world of information technology (IT) can be challenging or even frightening
to all of us. For any IT engineer who stays out of the technological advancement for even a very short
period of time, he/she will quickly find himself/herself an outsider to the technological transitions,
with difficulty in understanding hundreds and thousands of new terminologies that are invented every
year for newly emerging technologies....
Classical differential geometry is the approach to geometry that takes full
advantage of the introduction of numerical coordinates into a geometric
space. This use of coordinates in geometry was the essential insight of Rene
Descartes that allowed the invention of analytic geometry and paved the way
for modern differential geometry. The basic object in differential geometry
(and differential topology) is the smooth manifold. This is a topological
space on which a sufficiently nice family of coordinate systems or "charts"
Wireless e-business allows people to communicate and transact in business via
wireless technology, without physical connectivity, such as wires or cabling.
Wireless e-business uses many devices, including mobile phones, pagers, palmpowered
personal computers (PCs), pocket PCs, laptop computers, and other mobile
devices or devices connected to the wireless networks
In the last few years, the search for radically new approaches to software engineering has witnessed a great momentum. These efforts are well justified by the troubling state of present day computer science. Software engineering practices based on design-time architectural composition (the only assessed way of doing software engineering so far), lead to brittle and fragile systems, unable to gracefully cope with reconfiguration and faults.
