Supervisory control systems--Security measures; Automatic data collection systems--Security measures
This thesis describes the development of a prototype security hardened field device (such as a remote terminal unit) based on commodity hardware and implementing a previously developed security architecture. This security architecture has not been...
This thesis proposes a network based intrusion detection approach using anomaly detection and achieving low configuration and maintenance costs. A honeypots is an emerging security tool that has several beneficial characteristics, one of which is...
Remote terminal units (RTUs) are perimeter supervisory control and data acquisition (SCADA) devices that measure and control actual physical devices. Cyber security was largely ignored in SCADA for many years, and the cyber security issues that now...
Supervisory control systems--Security measures; Computer security; Security systems
This thesis documents the successful development and testing of a more secure industrial control system field device architecture and software. The implementation of a secure field device has had limitations in the past due to a lack of secure...
Many dedicated-use computer systems sold as complete products require a turn-key design delivered to the customer. This requires a system which is stable, secure, and serviceable. Adaptability of the system to existing software applications is a...
The management of power and the optimization of systems generating and using power are critical technologies. A new architecture is developed to advance the current state of the art by providing an intelligent and autonomous solution for power...
Digital control systems; Computer security; Process control--Computer programs; Supervisory control systems--Security measures
Supervisory control and data acquisition (SCADA) systems are networked control systems used in many critical infrastructure areas such as power water and transportation. Many of these systems continue to use legacy field devices that lack cyber...
Rootkits are stealthy, malicious software that allow an attacker to gain and maintain control of a system, attack other systems, destroy evidence, and decrease the chance of detection. Existing detection methods typically rely on a priori knowledge...
The use of a fluidized bed dryer to dry acrylo-nitrile-
butadiene-styrene terpolymer was studied. Data for
fluidized bed drying were obtained from the Monsanto
Company's fluid bed dryer. Fluid bed theory, drying
phenomena, and fluid bed drying...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
The heat pipe augmented solar wall operates much more efficiently for domestic air heating than alternative passive solar technologies. The thermal diode effect of heat pipes reduces the insulating losses of the unit during nighttime and adverse...
Emergency management--Kentucky; Assistance in emergencies--Kentucky; Disaster relief--Kentucky; Transportation--Planning
Large-scale emergencies caused by earthquake, tornado, pandemic flu, terrorism attacks and so on can wreak havoc to communities. In order to mitigate the impact of the events, emergency stockpiles of food, water, medicine and other materials have...
Existing treatment programs and procedures are incapable of addressing the complications encountered with patients who experience spasticity and hypertonia related joint contractures. Current passive therapy procedures and devices are only capable...
The use of franchise advisory boards, typically composed of franchisees and
franchisor representatives, is common practice in domestic and international franchise
systems. Because effective board collaboration requires teamwork, understanding...
A significant amount of effort has been put in developing tools to interpret Ground Penetrating Radar signals obtained during surveys. Currently, skilled and experienced users do most of GPR image interpretation. They use experience in deciphering...
Phase II clinical trial are generally single arm trial where a homogeneity assumption is placed on the response. In practice, this assumption may be violated resulting in a heterogeneous response. This heterogeneous or overdispersed response can be...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...
Solar energy--Technological innovations; Electric current rectifiers
Solar energy offers a large potential as a source of energy and in light of financial
and ethical reasons, people are looking to harvest it for their energy needs. The
conversion of solar energy to electricity is performed by solar cells. There...
This dissertation is composed of three essays in which I examine the influence of formal institutions on entrepreneurs and new firms. In the first essay, "The Influence of Institutions on the Likelihood of Self-Employment: A Multilevel...
