Bøger af Robert Siegfried

Seeking to enlarge an understanding of the nature of chemical science & explain how the concepts being taught in the classroom came to be, Siegfried presents a simple, readable account of how in the 18th cent. chemical composition slowly abandoned the centuries- long tradition of metaphysical elements of earth, air, fire, & water. Through the work of such scientist as Lavoisier, Dalton, & Davy, chemical theory moved from metaphysical elements to operationally functional atoms. The book is based on chemical writings of 17th- & 18th-cent. chemists; references to recently published secondary works are intended for the benefit of readers who wish to enlarge their perspectives on the development of early chemical thinking.

Robert Siegfried presents a framework for efficient agent-based modeling and simulation of complex systems. He compares different approaches for describing structure and dynamics of agent-based models in detail. Based on this evaluation the author introduces the "e;General Reference Model for Agent-based Modeling and Simulation"e; (GRAMS). Furthermore he presents parallel and distributed simulation approaches for execution of agent-based models -from small scale to very large scale. The author shows how agent-based models may be executed by different simulation engines that utilize underlying hardware resources in an optimized fashion.
