Thwarting Electromagnetic Fault Injection Attack Utilizing Timing Attack Countermeasure
… to properly model EMFI and develop effective countermeasures, a deeper understanding of the EM effect on a chip is needed. In this thesis, we present a bottom-up analysis of EMFI effects on a RISC microprocessor. We study these effects at three levels: at the wire-level, at the chip-network …

An investigation of network countermeasure against fast self-propagating malware
… a cross-layer architecture to provide a combined countermeasure solution against fast self-propagating malware, i.e., a detection technique at network layer and a containment technique at data link layer. Furthermore, an improved testing environment, termed V-Network, has been developed for high …

The Variable Vector Countermeasure Suit for space habitation and exploration
The Variable Vector Countermeasure Suit (V2Suit) is a countermeasure suit for sensorimotor adaptation and musculoskeletal deconditioning in microgravity. The V2suit will consist of modules containing arrays of control moment gyroscopes (CMGs) which will be controlled to provide viscous resistance …

Adaptive power control as a fade countermeasure on satellite links
Satellite systems in the 20/30 GHz band are very susceptible to outages due to rain-induced fades. In order to reduce the impact of these fades, it has been proposed that the power of the uplink station transmitter be adjusted during the fade to compensate. This dissertation will explore some of …

A critical benefit analysis of artificial gravity as a microgravity countermeasure
… to decondition during spaceflight. Several countermeasures that are in use today have been rigorously developed over the decades to combat this deconditioning. However, these countermeasures are system specific and have proven to be only partially effective. Artificial gravity has been …

Logistical Models For Planning And Operating Medical Countermeasure Distribution Networks During Public Health Emergencies
Public health emergencies require rapid responses from federal, state, and local authorities to prevent widespread mortality and morbidity. However, existing response plans seldom account for the variety of risks and uncertainties inherent in emergency scenarios. Our goal is to construct models …

Quantifying the Cognitive, Symptomatic and Neuroendocrine Impact of the Coriolis Illusion; A Countermeasure for Motion Sickness
… the effectiveness of a mild, ground-based countermeasure, similar to the Coriolis illusion, in reducing the occurrence and severity of symptoms. In the early stages of data analysis, there appeared to be a significant impact of the Coriolis illusion on cognitive performance and subjective …
