The Space Plug-And-Play Architecture Services Manager And Its Relevance In Diverse Plug-And-Play Software Systems, Brandon Holdaway

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Space Plug-and-Play Archichecture System Manager (SSM) is a system of Space Plug-and-Play Architecture (SPA) hardware, software components, and services for rapid integration of satellite systems. It was originally designed to help decrease the amount of time and money required to integrate payloads onto a satellite. The features of the SSM make it useful in non-satellite systems. In this report, I demonstrate diverse uses of the SSM in a multi-use payload manage- ment and underwater vehicle software solution which was designed and implemented using the SSM. Further I give a detailed explanation of the successes and failures of the software …

Re-Engineering Of A Black Box For The Purpose Of Upgrade And Maintenance, Nathanael R. Weidler

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

There existed an aging electrical system that needed to be upgraded. An upgrade was necessary for this system because the cost to maintain the aging technology was becoming too great. There were, however, no available schematics or technical papers describing this system. In order to upgrade the system, it first needed to be reverse engineered. The system to be upgraded was a device that would pass data back and forth from a personal computer to a proprietary storage device. The device to be upgraded communicated with the personal computer over a standard Small Computer System Interface (SCSI) interface and with …

Real-Time Scheduling Algorithm Design On Stochastic Processors, Anushka Pakrashi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent studies have shown that significant power savings are possible with the use of in-exact processors, which may contain a small percentage of errors in computation. However, use of such processors in time-sensitive systems is challenging as these processors significantly hamper the system performance. In this thesis, a design framework is developed for real-time applications running on stochastic processors. To identify hardware error pat- terns, two methods are proposed to predict the occurrence of hardware errors. In addition, an algorithm is designed that uses knowledge of the hardware error patterns to judiciously schedule real-time jobs in order to maximize real-time …

Physical Layer Detection Of Hardware Keyloggers, Saptarshi Mallick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This work addresses the problem of detecting devices which are stealthily attached to the computer for logging keystrokes from keyboards. These devices are known as hardware keyloggers (HKL). When an HKL is attached to the keyboard, certain electrical characteristics of the keyboard signal are altered. Based on these characteristics (features), differences have been identified in an accurate assertion was made about the presence of HKL.

The characteristics from which the differences were obtained were used to make distributions and compared with distance-measuring methods. An experiment was done to collect data from a number of keyboards and form two distributions (training …
