Self-stabilizing wormhole routing
… must cooperate to ensure proper routing; Wormhole routing is most common in parallel architectures in which messages are sent in small fragments called flits. We assume that each processor will contain a single fixed-size flit buffer for each incoming link. A processor must forward the …

Self-stabilizing wormhole routing in hypercubes
Wormhole routing is an efficient technique used to communicate message packets between processors when they are not completely connected. To the best of our knowledge, this is the first attempt at designing a self-stabilizing wormhole routing algorithm for hypercubes. Our first algorithm handles …

A Unified Wormhole Attack Detection Framework for Mobile Ad hoc Networks
… nodes are trustworthy for multi-hop routing. Wormhole attacks belong to most severe routing threats because they are able to disrupt a major part of the network traffic, while concomitantly being extremely difficult to detect. <br></br><br></br> This thesis presents a new unified wormhole …

The projective to Einstein correspondence and a kink on a wormhole
… is concerned with $\phi^4$ field theory on a wormhole spacetime in 3 + 1 dimensions. This spacetime has two asymptotically flat ends connected by a spherical throat of radius $a$. We show that the theory possesses a kink solution which is linearly stable, and compare its discrete spectrum to …

Near-optimal broadcast in all-port wormhole-routed hypercubes using error-correcting codes
… method is presented for hypercubes with wormhole routing mechanism. The communication model assumed allows an n-dimensional hypercube to have at most n concurrent I/O communication along its ports. It assumes a distance insensitivity of (n + 1) with no intermediate reception capability …

Wormhole Run-Time Reconfiguration: Conceptualization and VLSI Design of a High Performance Computing System
… a distributed reconfiguration mechanism called Wormhole Run-Time Reconfiguration (RTR) that allows multiple data ports to simultaneously program different sections of the chip independently. Used as the primary example of Wormhole RTR in the patent application, Colt is the first system to employ …

Quantum Effects of the Massless Spin One-Half Field in Static Spherically Symmetric Black Hole and Wormhole Spacetimes
… of three static spherically symmetric Lorentzian wormhole spacetimes. The field and all spacetimes studied are in a zero temperature vacuum state. We treat the field quantum mechanically on a classical background spacetime governed by general relativity. The full stress-energy tensor is found to …

Integrated optimization of hybrid steam-solvent injection in post-CHOPS reservoirs with wormhole networks and foamy oil behaviour under uncertainty
… both its in-situ generated open channels (i.e., wormholes) and induced foamy oil lead to a higher oil recovery than expected. Hybrid steam-solvent injection has been considered as the most effective recovery method for heavy oil reservoirs; however, the existence of wormhole networks makes it …

Traversable Wormholes in Kerr Black Holes
Wormholes have long been a source of interest in general relativity, having been first coined by John Wheeler in 1957. More recently, wormholes have proven instrumental to our understanding of quantum gravity, with particular interest being given to Euclidean wormholes and their relevance to the …
