Computer Memories 1
Storage, the computer’s second function, has become progressively more complex to meet growing needs in terms of capacity, speed, security and energy efficiency. It takes the form of a component or system, such as a memory subset or a mass storage device. With examples drawn from both current and older technologies, Computer Memories 1 begins by presenting the basics of the memory function, including the main characteristics of a generic memory, a technological and historical overview, and a definition of the concept of memory hierarchy. This book then details the internal functional organization of a random-access solid-state memory and the external aspects of a memory system. Complementary notions such as framing, information ordering and error detection/correction, as well as an introduction to error detection and correction codes, conclude the book. Philippe Darche is Lecturer in Computer Science at the University Institute of Technology (IUT) of Paris – Rives de Seine and Researcher in the Distributed Algorithms and Systems (DeLyS) team at LIP6, Sorbonne University, France. He is also the author of fifteen books on computer architecture.

Optimierung und Applikation des Lenkungs-Feedbacks in der Fahrsimulation unter Anwendung von künstlicher Intelligenz
In Fahrsimulatoren kommen zur generischen Erzeugung des Lenkradmoments voranging physikalische Modelle zum Einsatz, die nur mit großem Aufwand parametriert werden können und zudem eine hohe Rechenleistung benötigen. Mit Hilfe der hybriden Modellierung werden die Vorteile von physikalischer und Black-Box-Modellierung vereint, so dass künftig Lenksysteme von virtuellen oder existenten Fahrzeugen schnell und einfach erstellt werden können. Vor allem im für das Lenkgefühl relevanten On-Center-Bereich kann ein latenzarmes hybrides Open-Loop-Lenkungsmodell ein authentisches Lenkgefühl für Fahrsimulatoren mit Force-Feedback-System generieren.
