A network transparent, retained mode multimedia processing framework for the Linux operating system environment

Die Arbeit präsentiert ein Multimedia-Framework für Linux, das im Unterschied zu früheren Arbeiten auf den Ideen "retained-mode processing" und "lazy evaluation" basiert: Statt Transformationen unmittelbar auszuführen, wird eine abstrakte Repräsentation aller Medienelemente aufgebaut. "renderer"-Treiber fungieren als Übersetzer, die diese Darstellung zur Laufzeit in konkrete Operationen umsetzen, wobei das Datenmodell zahlreiche Optimierungen zur Reduktion der Anzahl der Schritte oder der Minimierung von Kommunikation erlaubt. Dies erlaubt ein stark vereinfachtes Programmiermodell bei gleichzeitiger Effizienzsteigerung. "renderer"-Treiber können zur Ausführung von Transformationen den lokalen Prozessor verwenden, oder können die Operationen delegieren. In der Arbeit wird eine Erweiterung des X Window Systems um Mechanismen zur Medienverarbeitung vorgestellt, sowie ein "renderer"-Treiber, der diese zur Delegation der Verarbeitung nutzt

Scalable Sort Automation

The Scalable Sort Automation MQP evaluates the effectiveness of a system level design for an automated sortation system that is scalable to high class count and high volume. Subsystems underwent low level design, prototyping, and evaluation of criteria such as cycle time, cost, and volume. The system architecture couples traditional sorting techniques such as linear grating and serialization with novel machine learning technology. The LEGO catalog is used as a base case in testing the subsystems, the catalog carries a high-class count of close to 70,000 with many of the classes being distinct in size, shape, weight and other mechanical properties and features. The system is then evaluated in an economic model centered around conducting LEGO aftermarket sales through bricklink.com
