Evaluation of concrete bridge deck overlays
… slag modified concrete. With these four selected overlays, statistical design of experiments were conducted for the evaluation of the influences on bond strength of four factors: aggregate types, surface preparations, use of bonding slurry, and substrate age using a recently developed direct shear …

Tensile relaxation of bonded concrete overlays
Restrained shrinkage in bonded concrete overlays can cause stress build up, cracking and even debonding. Tensile relaxation is the main mechanism of stress relief in concrete overlays. This results in less possibility of cracking and debonding. The research described in this study presents an …

Diffusion problems and degradation of bearing overlays
The corrosion and degradation of Pb-Sn bearing overlays Is a bilateral process . During service, the lubricant becomes corrosive due to the breakdown of inhibitors with subsequent oxidation occurring at operating temperatures (120-170[degrees]). ...

Electrical design of structurally tunable skin overlays
Current on-skin interfaces focus on enabling electronic circuitry and display-like output on top of the skin, but to the best of our knowledge interfaces for tuning the texture or stiffness of the skin itself are unexplored. We present SkinMorph, a second skin layer that alters its texture and …

Robustness of bus overlays in optical networks
Local area networks (LANs) nowadays use optical fiber as the medium of communication. This fiber is used to connect a collection of electro-optic nodes which form network clouds. A network cloud is a distribution network that connects several external nodes to the backbone, and often takes the form …

Evaluations of concrete overlays for bridge deck applications
Protective concrete deck overlays have been successfully used by WVDOH in a number of old and new concrete bridge decks to extend their service life, but in several cases delamination and failures have been observed. A comprehensive study has been recently defined to investigate overlays …

Evaluation of bonded concrete overlays on asphalt pavements
A field performance study of 19 bonded concrete overlays on asphalt pavements (BCOA) projects in 9 states were completed in this research study. BCOA pavements ranged in age from 7 to 26-years old and average thickness per project of 3.8 to 9.3 inches. The panel size varied from 4 ft x 4ft to 12 ft …

A programming environment for on-demand service overlays
Recent years have seen a growing interest in overlay networks. Overlay networks simplify the complications of creating and connecting distributed applications on the network by optimizing the underlying IP routing architecture. This thesis presents a programming environment (PEON) for automatically …

Zoning – Neighborhood Character and Historic Overlays in Lexington, KY
… district (H-1) and neighborhood character (ND-1) overlays have on home sale prices in Lexington, KY. Results suggests that overlays have a significant positive impact on home values. Results also suggest that that overlays exhibit spatial impacts that extend further than the homes included in the …

Mechanistic characterization of thin asphalt overlays for pavement preservation
Thin asphalt concrete (AC) overlays are generally used as a preservation treatment for rigid and flexible pavements to improve ride quality, extend service life, and reduce noise levels on pavements. However, compared to the conventional methods of mechanistic analysis, analyzing thin AC overlay is …

Long-term performance of bonded concrete overlays subjected to differential shrinkage
The performance of bonded concrete overlays relates mainly to the resistance against cracking and debonding. The associated failure mechanisms are largely a result of differential volume changes between substrate and overlay. The objective of this research was to develop analytical tools to …

The Use of Colored Overlays in Reading with Sixth Grade Learning Disabled Students
The use of clear, colored overlays has been proposed to improve reading skills by filtering out portions of the visible light spectrum with which learning disabled individuals may experience difficulty while reading. This study investigates whether a significant relationship exists between the use …

Topology overlays for dedicated protection Ethernet LAN services in advanced SONET/SDH networks
… groups using bus and minimum spanning tree (MST) overlays. Next, advanced multi-path routing schemes are used to provision and protect these individual overlay connections using the inverse-multiplexing capabilities of NGS. Finally, post-fault restoration features are also added to handle expanded …
