same initial elements. For the case of m= 12 this results in a reduction by a factor of about 80 in the number ofcases examined. Samples at m = 13 and 14 indicate that this pruning method will yield an additional improvement factor of about 2.5 to 3 for each increase in m. Using a characteristic vector representation, the test for a repeated spacing is improved by a factor of m2/8 over the stra...

Handheld Computers as Cognitive Tools: Technology-Enhanced Environmental Learning

This design-based research uses handheld computers as cognitive tools to facilitate students’ inquiry-based learning on environmental issues — 3Rs (Reduce, Reuse and Recycle) in a Singapore primary school. Using handheld computers throughout a field trip, 79 Primary grade 4 students investigated how wastes are produced and what impact 3Rs can have on protecting the environment. The handheld com...

Chemical Process Simulation on Parallel Computers

We have developed a core code to model the cylindrical polar and Cartesian incompressible turbulent Navier-Stokes equations with application to chemical reactor problems. A conventional co-located finite volume method is used to discretise the conservative form of the partial differential equations. The pressure velocity coupling is solved using the SIMPLE algorithm with the resulting sets of e...

Microreactors as tools for chemical research

The unique operational characteristics of microreactors are described in this article, with particular reference to their use as tools for chemical synthesis. With reference to the future automation, an example is presented to illustrate how microreactors can be readily integrated into current HPLC systems, to enable fully integrated chemical synthesis and product analysis to be performed.
