100BASE-T has enhanced the performance of Ethernet networks from 10 to 100 Mbps. However, an Ethernet network under high offered load can produce unpredictable and excessive packet delays due to the capture effect introduced by the Binary Exponential Backoff (BEB) algorithm. A solution that efficiently overcomes this problem is the PACE algorithm. This paper presents a performance analysis of s...

An all digital QAM system is studied here for high-speed data transmission on digital subscriber loops. All elements of the system have been fully investigated and their effects on the overall system performance documented. In particular the following issues have been explicitly addressed: utility of an adaptive error-prediction (noise-prediction) filter; equalizer size and convergence; blind e...

Abstract Power system faults can often result in excessively high currents. If sustained for a long time, such currents damage equipment. Thus, it is desirable to operate the relays minimum possible time. In this paper, busbar splitting approach used adaptive relay setting and co-ordination purposes integrity protection scheme (SIPS). Whenever fault occurs, splits bus convert loop into radial s...

Standardization of 3 Generation (3G) mobile communication systems has produced the first specification releases and the commercial deployment of the 3G systems has started. Whereas 1G and 2G focused on efficiently providing voice services, in 3G a lot of attention has been devoted to solutions that support both Circuit Switched (CS) and Packet Switched (PS) communication. That has called for ve...

We have examined the fine specificity of a panel of cloned T cell hybridomas generated from Lewis rats immunized with guinea pig (GP) or Lewis rat myelin basic protein (MBP) to determine the autoimmune T cell repertoire that develops in experimental allergic encephalomyelitis (EAE). This analysis has demonstrated that GP MBP, which was approximately 10-fold more potent for EAE induction than th...

The myelin basic proteins (MBPs) mediate the cytoplasmic apposition of the oligodendrocyte plasma membrane to form the major dense line of central nervous system myelin. Four major isoforms of murine MBP, obtained by alternative splicing of seven exons from a single primary transcript, display distinct developmental profiles. We expressed these major MBPs individually in HeLa cells and mapped t...

One interesting problem regarding wireless local area network (WLAN) ad-hoc networks is the effective mitigation of hidden nodes. The WLAN standard IEEE 802.11 provides request to send/clear to send (RTS/CTS) as mitigation for the hidden node problem; however, this causes the exposed node problem. The first 802.11 standard provided only two transmission rates, 1 and 2 Mbps, and control frames, ...
