Contraction-Expansion Protocols.
<p>An approach to a new class of compounds known as bridgehead dienone is described. The route is based on a tandem contraction-expansion event in which the contraction triggers the expansion. The two steps involved are a palladium-catalyzed Favorskii contraction and a <em>cis</em>-divinyl …

Self-stabilizing routing protocols
In systems made up of processors and links connecting the processors, the global state of the system is defined by the local variables of the individual processors. The set of global states can be defined as being either legal or illegal. A self-stabilizing system is one that forces a system from …

Self-stabilizing network protocols
… protocol, and the RFMDS system. These modified protocols are shown to be more fault tolerant and robust than their corresponding existing protocols. (Abstract shortened by UMI.).

PROTOCOLS FOR QUANTUM NETWORKS
… involved, the architecture of these networks and protocols to operate them are completely different from the classical networks. Therefore, many building blocks of the classical networks do not translate to the quantum networks and require novel solutions of their own. Moreover, since the field is …

Per-hop Internet Measurement Protocols
Accurately measuring per-hop packet dynamics on an Internet path is difficult. Currently available techniques have many well-known limitations that can make it difficult to accurately measure per-hop packet dynamics. Much of the difficulty of per-hop measurement is due to the lack of protocol …

Multiparty Protocols for Tree Classifiers
… designing and analyzing encryption schemes and protocols that protect data from unauthorized reading. However, in our modern information-driven society with highly complex and interconnected information systems, encryption alone is no longer enough as it makes the data unintelligible, preventing …

Meta-standardisation of interoperability protocols
The current medley of interoperability protocols is potentially problematic. Each protocol is designed by a different group, each provides a single service, and has its own syntax and vocabulary. Popular protocols such as RSS are designed with simple and easy to understand documentation, which is a …

Games, protocols, and quantum entanglement
… analyzing complexity-theoretic or cryptographic protocols in a quantum world: the soundness or security of the protocol may no longer hold in the presence of entangled adversaries. This thesis presents several results involving games and protocols with entangled parties; in each result, we …

Improving Performance of Consensus Protocols
… it is long known that there exist randomized protocols that can achieve BB in expected constant rounds, regardless of the number of nodes n. However, whether we can match the expected constant round complexity in the corrupt majority setting — or more precisely, when f ≥ n/2 + ω(1) — was …

Formally modeling, analyzing, and designing network protocols : a case study on retransmission-based reliable multicast protocols
… retransmission-based reliable multicast protocols. We first present an abstract model of the communication service that several reliable multicast protocols [12, 13, 32-34] strive to provide. This model precisely specifies i) what it means to be a member of the reliable multicast group, …

Fingerprint testing protocols for optical sensors
… variety of conflicting and contradictory testing protocols for biometric technologies. There is currently no biometrics testing standard, which allows vendors to skew their test results in their favor. The research discussed in this thesis aims to address these issues by developing and validating …

Lightweight cryptographic protocols for mobile devices
… lightweight polynomial-based cryptographic protocols in three environments that encompass resource-constrained devices which are Wireless Sensor Network (WSN), Fog Computing, and Blockchain Network. With polynomial-based schemes, we guarantee high network connectivity due to the existence of …

Alternate Routing Protocols for Bridged Networks
… networks by introducing two alternate routing protocols. We design a novel bridge protocol that can forward frames on paths that are provably shorter than the paths that the standard provides. This protocol is called the Spanning Tree Alternate Routing (STAR) Bridge Protocol. STAR bridge …

Multichannel Wireless Networks: Capacity and Protocols
… Detailed simulation-based evaluations of the protocols have shown that multiple channels can be used to significantly enhance network capacity, even if only a few interfaces per node are available. We have implemented the protocols in a testbed to demonstrate the feasibility of using the …
