We present an advanced and comprehensive semiconductor optical amplifier model to analyze the propagation and amplification of 10 to, in principle, 1280 Gb/s ultra-short optical pulse sequences. Through appropriate transformation, the partial differential propagation-rate equation problem is numerically solved in a two-dimensional grid of fine resolution. The corresponding simulator, entirely programmed in the graphicallanguage LabVIEW, is compared to an identical simulator implemented in the popular high-level text-based language Matlab. Special care has been taken to implement the same set of algorithms using equivalent codes for each language, such that a fair and objective one-to-one comparison can be carried out. In terms of computational time the LabVIEW Simulator shows a tenfold outperformance, compared to its text-based identical counterpart implemented in Matlab, when typical bit sequences at 40 Gb/s with a length of 8 to 1024 bits are tested. The performance results presented here apply to a broader set of device modeling scenarios. (c) 2005 Elsevier B.V. All rights reserved.

To provide high-level graphical support for PVM (Parallel Virtual Machine) based program development, a complex programming environment (GRADE) is being developed. GRADE currently provides tools to construct, execute, debug, monitor and visualize message-passing parallel programs, It offers a high-level graphicalprogramming abstraction mechanism to construct parallel applications by introducing a new graphicallanguage called GRAPNEL. GRADE also provides the programmer with the same graphical user interface during the program design and debugging stages. A distributed debugging engine (DDBG) assists the user in debugging GRAPNEL programs on distributed memory computer architectures. Tape/PVM and PROVE support the performance monitoring and visualization of parallel programs developed in the GRADE environment.

This thesis describes the development of personal computer interfaces for the Digital Control Subsystem (DCS) and Electrical Power System (EPS) of the Naval Postgraduate School's Petite Amateur Navy Satellite Simulator project. The work includes a brief description of related PANSAT and PANSAT simulator subsystems. The laboratory activity that provided the information for this work, namely, programming in the Lab VIEW software programs G graphical programming language, involved the generation of programming code for controlling and reading data from the simulators component subsystems. Where appropriate, there is limited discussion of key satellite and simulator component designs and installations. Through the use of documentation and illustrative figures, the programming and display components of the interfaces are shown to be functional in the simulator environment. Instructions for making anticipated design accomodations are included.
