This document specifies how the level 3 multihoming shim protocol (SHIM6) detects failures between two communicating hosts. It also specifies an exploration protocol for switching to another pair of interfaces and/or addresses between the same hosts if a failure occurs and an operational pair can be found.

p-Cycles can attain high capacity efficiency and fast protection switching times in WDM networks. The number of deployed p-cycles and the ability to survive dual fiber duct failures are further important characteristics which are considered in a pan-European network case study. We show that the dual failure restorability and the protection capacity can vary significantly for cycle-configuration...

a unique high frequency transient overvoltage surge suppressor for the protection of motors and transformers from steep wave-front, short rise-time, high magnitude, spikes, surges and other transient voltages, generated by switching, lightning and other sources. The protective characteristics of ZORC: Eliminates inter-turn insulation failures Extends the life of machine insulation Eliminates mu...

The expectation of a random variable is its average value, where each value is weighted according to the probability that it comes up. The expectation is also called the expected value or the mean of the random variable. For example, suppose we select a student uniformly at random from the class, and let R be the student’s quiz score. Then E [R] is just the class average —the first thing everyo...

Today in the electric power industry of Ukraine issue assessing risk EPS operation due to failures electrical equipment is particularly important. Failures are associated with significant level aging and low replacement rates equipment, also possible simultaneous emergency decommissioning several elements as a result terrorist attacks.
 Based on analysis operating conditions high-voltage s...

This paper proposes a novel dataflow architecture called DFNET (DataFlow architecture on the interNET), which realizes a scalable dynamic dataflow computer on a packet switching network. A vast amount of research on dataflow computers has been extensively performed during, in particular, 1970s and 1980s as a promising approach for realizing very high-speed computers. In spite of the large amoun...

This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). We unify various forms of segment protection into generalized segment protection (GSP). In GSP, the working path of a lightpath is divided into multiple overlapping working segments, each of which is protect...

INTRODUCTION Rilpivirine (RPV) has a better lipid profile than efavirenz (EFV) in naïve patients (1). Switching to RPV may be convenient for many patients, while maintaining a good immunovirological control (2). The aim of this study was to analyze lipid changes in HIV-patients at 24 weeks after switching to Eviplera® (emtricitabine/RPV/tenofovir disoproxil fumarate [FTC/RPV/TDF]). MATERIALS ...
