The aging of reinforced concrete structures is one the biggest concerns in civil engineering today since billions dollars are spent annually on deck repairs and replacements. This study focuses rehabilitation box girders used bridge construction. Bridge with a new overlay possesses many challenges that involve cracking debonding caused by restraining effect substrate. leads to development tensi...

Many structured overlay networks rely on a ring invariant as a core network connectivity element. The responsibility ranges of the participating peers and navigability principles (greedy routing) heavily depend on the ring structure. For correctness guarantees, each node needs to eagerly maintain its immediate neighboring links the ring invariant. However, the ring maintenance is an expensive t...

in order to adapt lasota strain of newcastle disease virus (ndv) on chick embryo fibroblast (cef) cells, 0.1 ml from lasota vaccine produced in razi vaccine and serum research institute inoculated to the cef cells and was passaged five times in the cef grown in eagle’s minimum essential medium (mem). first to third passages were blind but in fourth passage cytopathic effect of virus was observe...

We present a transaction processing scheme for structured overlay networks and use it to develop a distributed Wiki application that is based on a relational data model. The Wiki supports rich metadata and additional indexes for navigation purposes. Ensuring consistency and durability requires handling of node failures. We mask such failures by providing high availability of nodes by constructi...

From the idea of using an array of isolated wireless ports called Infostations, we consider the use of existing cellular infrastructure as the location for these Infostations. The coverage area of Infostations, though, will be smaller than the cell area. We determine the worst-case SIR as a function of the coverage-radius-to-cell-radius ratio and the frequency-reuse cluster size. For specific m...

We introduce an architecture for “Intradomain Overlays”, where a subset of routers within a domain is augmented with a dedicated host. These strategically placed hosts form an overlay network, and we describe a number of applications for such overlays. These applications include efficient network monitoring, policyand load-based packet re-routing, and network resource accounting. In this paper,...
