A First Course of Chemistry (Heuristic)

Heuristic Approach to Organic Chemistry

An important question in organic chemistry is how does a chemist synthesize chemicals in the most efficient way beginning with chemicals readily available. These problems are known as synthesis problems. Currently, methods based on databases (Chen, 2006) and methods related to quantum mechanics (Jorgensen, 1998) are used frequently to solve this problem. When solving synthesis problems by hand,...

effects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english

to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...

Breadth-First Heuristic Search

Recent work shows that the memory requirements of bestfirst heuristic search can be reduced substantially by using a divide-and-conquer method of solution reconstruction. We show that memory requirements can be reduced even further by using a breadth-first instead of a best-first search strategy. We describe optimal and approximate breadth-first heuristic search algorithms that use divide-and-c...

A First Course in Hydraulics

This course of lectures is an introduction to hydraulics, the traditional name for fluid mechanics in civil and environmental engineering where sensible and convenient approximations to apparentlycomplex situations are made. An attempt is made to obtain physical understanding and insight into the subject by emphasising that we are following a modelling process, where simplicity, insight, and ad...
