Alternative Mission Concepts For The Exploration Of Outer Planets Using Small Satellite Swarms, Andrew Gene Blocher

Master's Theses

Interplanetary space exploration has thus far consisted of single, expensive spacecraft missions. Mission costs are particularly high on missions to the outer planets and while invaluable, finite budgets limit our ability to perform extensive and frequent investigations of the planets. Planetary systems such as Jupiter and Saturn provide extremely complex exploration environments with numerous targets of interest. Exploring these targets in addition to the main planet requires multiple fly-bys and long mission timelines. In LEO, CubeSats have changed the exploration paradigm, offering a fast and low cost alternative to traditional space vehicles. This new mission development philosophy has the potential …

Embedded Processors On Fpga: Hard-Core Vs Soft-Core, Vivek J. Vazhoth Kanhiroth

Masters Theses

Field Programmable Gate Arrays (FPGAs) are integrated circuits (ICs) that can be reprogrammed by the consumer after manufacturing. They are based on a matrix of configurable logic blocks connected via programmable interconnects that enables the designer to quickly recreate hardware circuits. In the past, FPGAs were primarily used for prototyping and debugging purposes. However, with their increased popularity, many commercial products now incorporate FPGAs.

In the late 1990s, FPGA vendors introduced System-on-chip (SoC) devices that housed one or more hard-core processors and an FPGA fabric on a single IC to allow for more complex designs that involved hardware and software …

Speculations On A City For Mars, Edouard Terzis

School of Architecture - Theses

This thesis proposes the reinterpretation of architectural forms as the index of the constitution of the idea of the city. “Speculations on a City on Mars” is paradoxical in a sense as it superposes both the managerial representation of a city, that is Zoning, along with the speculative aspect of an extra-terrestrial city.

High-Speed Programmable Fpga Configuration Memory Access Using Jtag, Ammon Bradley Gruwell

Theses and Dissertations

Over the past couple of decades Field Programmable Gate Arrays (FPGAs) have become increasingly useful in a variety of domains. This is due to their low cost and flexibility compared to custom ASICs. This increasing interest in FPGAs has driven the need for tools that both qualify and improve the reliability of FPGAs for applications where the reconfigurability of FPGAs makes them vulnerable to radiation upsets such as in aerospace environments. Such tools ideally work with a wide variety of devices, are highly programmable but simple to use, and perform tasks at relatively high speeds. Of the various FPGA configuration …
