Parity filter automata are a class of two-st a te cellular aut omata on the intege r grid po ints of t he real line in which cells are updated serially from left to right in each time period ra.ther than 5YOchronously in parallel. Parity filter auto mata support large numbers of "par ticles," or persistent repeating configurations, and the collision of these particles is frequently a. "soliton"...

The mental decline of King Henry VIII from being a jovial, charismatic and athletic young man into an increasingly paranoid, brutal tyrant in later life, ever more concerned at his lack of one or more male heirs, has attracted many medical diagnostic theories. Previous hypotheses have included diabetes, syphilis and hypothyroidism, among others. However, these inadequately explain Henry's failu...

Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to heir thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed periodic temperature changes up to 00 K with a frequency of 0.05 Hz. However, a broad temperature gradient of 80 K developed inside the reactor. A...

E ngineering students in '.:heir senior year are anxious to translate theory into application. Most engineering curricula require a design course that accords senior students this practical experience, and design course faculty strive to offer a variety of projects to their students. Most of these projects, however, are not directly related to human needs; therefore, suggestions for projects th...

This article uses Bourdieu’s analysis of peasant life in the Bearn to illuminate a changing but resilient rural culture in mid-twentieth century Wales. Rather than finding their culture and language eroded by economic and social change, Welsh speaking participants in this biographical study used the education system to build upon their existing cultural capital previously cultivated through rel...

bstract. Image thresholding is a very common image processing peration, since almost all image processing schemes need some ort of separation of the pixels into different classes. In order to etermine the thresholds, most methods analyze the histogram of he image. The optimal thresholds are often found by either minimizng or maximizing an objective function with respect to the values of he thre...

This research was conducted to evaluate the effectiveness of a distraction technique in reducing young children’s negative responses to dental care. Fifty-five dentally naive children, ranging in age from two to six years, were studied over a sedes of four dental visits. Patients in the distraction condition viewed familiar ch3"ldren’s television programs throughout heir dental visits; patients...
