Cities and Complexity: Understanding Cities with Cellular Automata, Agent-Based Models, and Fractals
Author: Michael Batty
As urban planning moves from a centralized, top-down approach to a decentralized, bottom-up perspective, our conception of urban systems is changing. In Cities and Complexity, Michael Batty offers a comprehensive view of urban dynamics in the context of complexity theory, presenting models that demonstrate how complexity theory can embrace a myriad of processes and elements that combine into organic wholes. He argues that bottom-up processes -- in which the outcomes are always uncertain -- can combine with new forms of geometry associated with fractal patterns and chaotic dynamics to provide theories that are applicable to highly complex systems such as cities.
Batty begins with models based on cellular automata (CA), simulating urban dynamics through the local actions of automata. He then introduces agent-based models (ABM), in which agents are mobile and move between locations. These models relate to many scales, from the scale of the street to patterns and structure at the scale of the urban region. Finally, Batty develops applications of all these models to specific urban situations, discussing concepts of criticality, threshold, surprise, novelty, and phase transition in the context of spatial developments. Every theory and model presented in the book is developed through examples that range from the simplified and hypothetical to the actual. Deploying extensive visual, mathematical, and textual material, Cities and Complexity will be read both by urban researchers and by complexity theorists with an interest in new kinds of computational models.

Computer Forensics: Computer Crime Scene Investigation
Author: John R Vacca
The Most Comprehensive, Up-to-Date, Reference on Computer Forensics!
Using personal computers as their weapons, hackers and criminals (some only 11 years old) have attacked the Internet, government agencies, financial companies, small businesses, and the credit card accounts of unsuspecting individuals. This completely updated book/CD package provides a complete overview of computer forensics from information security issues to "crime scene investigation," seizure of data, determining the "fingerprints" of the crime, and tracking down the criminals. The book's companion CD-ROM contains demos of the latest computer forensics software. Numerous exercises, case studies, and vignettes of actual crimes enhance the topics under discussion, and provide the reader with solutions to computer crime in the real world.
