there are different studies in urban literature on the determinants of urban growth, from the theoretical and empirical points of view. the most completed theoretical model is henderson model (1988, 1997, and 1999), which is tested by some empirical studies. as henderson model shows, the set of national product, specialization and technological progress are the determinants of urban growth. usi...

In 2 earlier sets of experiments, the author reported that shape discrimination in an otherwise empty visual field is facilitated when the target shape is preceded by a valid spatial precue (J. M. Henderson, 1991; J. M. Henderson & A. D. Macquistan, 1993). L. Shiu and H. Pashler (1994) recently suggested that these earlier results were due to the presence of multiple posttarget pattern masks. T...

As an air pollutant is transported from a source to a potential receptor the pollutant disperses into the surrounding air so that it arrives at a much lower concentration than it was on leaving the source. Strict environmental regulations worldwide resulted in an ever growing concern about the validity and reliability of air quality dispersion models. The present work is a try to evaluate the a...

Techniques for object-oriented software development range from well established (such CRC cards, scenario analysis and object/class modeling) to newer developments. In this tutorial will be included some of the more recent developments within OPEN (Henderson-Sellers and Graham, 1997). These are likely to be selected from, for example, distributed computing, roles, rule modeling, project managem...
