A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...
Musical pitch--Data processing; Sound--Recording and reproducing--Digital techniques
Many mathematical formulas and algorithms exist to identify pitches formed by human voices, and this has continued to be popular in the fields of music and signal pro-cessing. Other systems and research perform real time pitch identification...
Outerplanar graphs are planar graphs that have a plane embedding in which each vertex lies on the boundary of the exterior region. An outerplanar graph is maximal outerplanar if the graph obtained by adding an edge is not outerplanar. Maximal...
The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their...
Supervisory control systems--Security measures; Automatic data collection systems--Security measures; Drinking water--Security measures; Computer networks--Security measures
Supervisory control and data acquisition (SCADA) systems are used by many critical infrastructures including electric power production and distribution, water and waste water treatment, rail transportation, and gas and oil distribution. Originally...
Most of the structures in submillimeter-scale engineering are created from thin films, making them essentially two-dimensional (2D). Significant work has been done to fabricate 3D structures using self-folding, a deterministic form of...
Electronic surveillance; Information technology--Social aspects; Computer networks--Design and construction
Because of the anonymity that P2P networks provide, they are an ideal medium for
the exchange of contraband material such as child pornography. Unfortunately, not
much research has been conducted on how to best monitor these types of networks
for...
Given a metric space (K, d), the hyperspace of K is defined by H(K) = {F c K: F is compact, F ≠ 0}. H(K) is itself a metric space under the Hausdorff metric dH. Hyperspaces have been extensively studied by topologists since the 1970's, but the...
A class of RC active filters in which the DC offset of the operational amplifier (op-amp) is completely absent from the filter output [1]. Individual filter configurations (Low Pass, High Pass, Band Pass, Band Stop, All Pass) are discussed and...
Narrative causal understanding is related to a variety of school-related skills such as reading comprehension, and memory. Previous research shows a developmental trend in the ability to use and understand causal connections that begins at age 4...
Background: Infection preventionists (IPs) have a multitude of tasks aimed at the prevention and control of infections in the healthcare setting. These tasks require a great deal of knowledge that has been more challenging to gain over the past...
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...
Supervisory Control and Data Acquisition (SCADA) systems are used in almost
all industrial processes including use in the nation's critical infrastructure. The electric,
water, and gas industries are merely a few that rely heavily on the use of...
Osteoporosis has become a growing health threat with rising social and economic consequences. The understanding of the relationship between bone mechanical strength and bone structural quality is important for the diagnosis of osteoporosis and the...
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...
Data libraries--Security measures; Computer networks--Security measures; Information storage and retrieval systems; Digital preservation
Data centers (DC) are the core of the national cyber infrastructure. With the incredible growth of critical data volumes in financial institutions, government organizations, and global companies, data centers are becoming larger and more...
Cardiology--Research--Methodology; Microfluidics--Equipment and supplies
Cardiovascular disease (CVD) is the leading cause of death in the United States and accounts for nearly 1,372,000 deaths each year. In addition, ~81 million Americans suffer from some form of CVD. Understanding the molecular basis of various...
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...
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...
Due to the overwhelming increase in open source code, off-the-shelf software packages, third party and vendor codes, along with the ease of getting information about hacking network security systems and attacking the well known holes in security...
