The paper extends Lindenmayer systems in a manner suitable for simulating the interaction between a developing plant and its environment. The formalism is illustrated by modeling the response of trees to pruning, which yields synthetic images of sculptured plants found in topiary gardens.
Systems with large amounts of computing power and storage are required to simulate very large neural networks capable of tackling complex control problems and real-time emu-lation of the human sensory, language and reasoning systems. General-purpose parallel computers do not have communications, processor and memory architectures optimized for neural… (More)
Through support from the National Institutes of Health's National Center for Research Resources, the Biomedical Informatics Research Network (BIRN) is pioneering the use of advanced cyberinfrastructure for medical research. By synchronizing developments in advanced wide area networking, distributed computing, distributed database federation, and other… (More)
BACKGROUND AND OBJECTIVE The Global initiative for chronic Obstructive Lung Disease (GOLD) Committee has proposed a chronic obstructive pulmonary disease (COPD) assessment framework focused on symptoms and on exacerbation risk. This study will evaluate a symptom and exacerbation risk-based treatment strategy based on GOLD in a real-world setting in Japan.… (More)
On January 2, 2000, The University of Calgary began offering its Games Programming course for the first time. This unique course, which runs as a partnership between the university and the games industry, has run annually since that time. Over the past 15 years the course has evolved with the changing technological and social landscapes of gaming. This… (More)
