When writing can change your life, when writing can enrich you by offering much money, why don't you try it? Are you still very confused of where getting the ideas? Do you still have no idea with what you are going to write? Now, you will need reading. A good writer is a good reader at once. You can define how you write depending on what books to read. This optics of light scattering media prob...

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers

This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...

Modelling Scale in Geographical Information Science. Edited by Nicholas J. Tate and Peter M. Atkinson (Chichester: John Wiley and Sons, 2002). [Pp xv+277]. ISBN 0-471-98546-5. Hardback

The way we perceive, measure, and construct geographic reality is inextricably linked to the spatial and temporal scale at which we observe that reality. This has led many to search for a better understanding and description of the influences of scale on geographic processes, with the ultimate goal of obtaining a scale-independent description of reality. It is in this context that Modelling Sca...
