Fracture characterization of thin bonded asphalt concrete overlay systems
Asphalt overlays provide an economical means for treating deteriorated pavements. Thin bonded overlay (TBO) systems have become popular options for pavement rehabilitation. In addition to functional improvements, these systems ensure a high degree of waterproofing benefits. Conventional asphalt …

Service life determination of concrete bridge decks and bridge deck overlay systems
… decks. Numerous bridge deck protection and overlay systems have been developed to reduce the deterioration rate caused by chloride-induced corrosion. This study investigated the service life of untreated concrete bridge decks and four bridge deck overlay systems: low-slump-dense concrete …

Asphalt Pavement Aging and Temperature Dependent Properties Using Functionally Graded Viscoelastic Model
… and accuracy of simulations for asphalt pavement systems. Some of the practical implications of this work include the new technique's capability for accurate analysis and design of asphalt pavements and overlay systems and for the determination of pavement performance with varying climatic …

Application of Fracture Mechanics to Assess Reflective Cracking Potential in Airfield Pavements
… When temperature gradients were present in overlay systems, the critical overlay responses were raised dramatically. As the friction coefficients between slabs and CTB increased, the calculated J-value and mode I SIFs were reduced gradually. Since the center of Boeing 777 gear loads was away …

Cognitive radios : fundamental limits and applications to cellular and wireless local networks
… the information-theoretic capacity of such systems is of great interest. Also, the design of cognitive radio is necessary to achieve those capacities in real applications. In this dissertation, we formulate different problems that relate to the performance of such systems and methods to …

NATRON : overlay routing to oblivious destinations
This thesis presents NATRON, a system in which an overlay network of nodes cooperates to improve unicast routing to non-participating hosts. Previous overlay systems have used overlay routing to improve communication between participating hosts; they were unable to exploit overlay routing to …

Evaluation of concrete bridge deck overlays
Overlay systems have been used by many states for the protection of bridge decks, but the premature delaminations and failures have been observed in many cases. A comprehensive study was recently defined to investigate overlay performance in collaboration with the West Virginia Department of …

Generic Adaptive Handoff Algorithms Using Fuzzy Logic and Neural Networks
… and Quality of Service (QoS) of cellular systems. This research presents novel approaches for the design of high performance handoff algorithms that exploit attractive features of several existing algorithms, provide adaptation to dynamic cellular environment, and allow systematic …

IMPROVEMENT OF CONCRETE OVERLAY DESIGN PROCEDURES
… research was to improve the current concrete overlay design procedures. As of 2016, TxDOT manages a total of 16,327 lane miles of Portland cement concrete (PCC) pavement, which represents an important asset to TxDOT. As PCC pavements in Texas built in the 1960s through 1980s have already …

Stress Transfer and Structural Failure of Bilayered Material Systems
Bilayered material systems are common in naturally formed or artificially engineered structures. Understanding how loads transfer within these structural systems is necessary to predict failure and develop effective designs. Existing methods for evaluating the stress transfer in bilayered materials …

Spectrum-Aware Orthogonal Frequency Division Multiplexing
Reconfigurable computing architectures are well suited for the dynamic data flow processing requirements of software-defined radio. The software radio concept has quickly evolved to include spectrum sensing, awareness, and cognitive algorithms for machine learning resulting in the cognitive radio …
