The Grand Alliance HDTV System has been designed for the needs and requirements of North America. The system has a great deal of flexibility to facilitate inter-operability and is heavily based on international standards. The Grand Alliance and the FCC Advisory Committee on Advanced Television Service have been working together to complete the design of the Grand Alliance HDTV System. When a te...

This dissertation will elaborate on the understanding of intersubjective meaning making by analyzing the traces of collaborative knowledge construction users leave behind in socio-technical systems. Therefore, it will draw upon more theoretical and more formal models of cognitive psychology to describe and explain the underlying process in detail. This is done with the goal to support intersubj...

Software transformation methods are enacted during a migration project to perform the technical transition of a legacy system to a new environment. A critical task of each project is to construct a situation-specific transformation method. In this paper, we categorize current Situational Method Engineering (SME) approaches that support the construction of situation-specific transformation metho...

On August 3, 1968, the Joint Resolution of the Congress established the program and construction of the Lister Hill National Center for Biomedical Communications. The facility dedicated in 1980 contains the latest in computer and communications technologies. The history, program requirements, construction management, and general planning are discussed including technical issues regarding cablin...

We propose a Hodge field theory construction that captures algebraic properties of the reduction of Zwiebach invari-ants to Gromov-Witten invariants. It generalizes the Barannikov-Kontsevich construction to the case of higher genera correlators with gravitational descendants. We prove the main theorem stating that algebraically defined Hodge field theory correlators satisfy all tautological rel...
