Routing protocols for wireless sensor networks face two challenges. One is an efficient bandwidth usage which requires minimum delay between transfers of packets. Establishing permanent routes from the source to destination addresses this challenge since the received packet can be immediately transmitted to the next node. However, any disruption on the established path either causes packet loss...

In Opportunistic Networks, information forwarding is involved when nodes are in range. Absence of network topology knowledge of Opportunistic Network makes information forwarding the most compelling challenge. Endto-end communication in Opportunistic Networks is supported naturally through nodes’ mobility. Disconnected peers are opportunistically connected to each other dynamically as informati...

In this paper, we analyze the performance of a new cooperative diversity scheme based on best relay selection with interferences at relay nodes, only relay node can be affected by interference. For the selection scenario, only a best relay that maximizes the end-toend received signal-to-interference and noise ratio (SINR) at the destination is selected to forward the information. Through statis...

This study explores the hotel selection patterns of leisure travellers to understand their loyalty or variety seeking intentions and profile them through key characteristics, factors that influence consumption patterns. While data were collected via focus groups, twenty-two participants purposively sampled based on criteria-Australian who have been same international destination three times mor...

BACKGROUND Discharge destination, either home or skilled care facility, after total knee arthroplasty (TKA) may be associated with significant variation in postacute care outcomes. The purpose of this study was to characterize the 30-day postdischarge outcomes after primary TKA relative to discharge destination. METHODS All primary unilateral TKAs performed for osteoarthritis from 2011-2014 w...

In this paper, the outage performance of automatic repeat request (ARQ) based opportunistic relaying is analyzed when the channel state information (CSI) for relay selection is outdated. The outage probability is derived in terms of correlation between SNR and outdated SNR of the channel from the selected relay to destination. It is shown that simulation results of the outage probability match ...

Network Design problems concern the selection of arcs in a graph in order to satisfy, at minimum cost, some flow requirements, usually expressed in the form of origin-destination pair demands. Benders decomposition methods, based on the idea of partition and delayed constraint generation, have been successfully applied to many of these problems. This article presents a review of these applicati...

F railty is the aggregation of subclinical physiological insults across many organ systems resulting in a syndrome of heightened vulnerability in the face of stress. Measures of frailty are highly predictive of adverse outcomes in many medical and surgical populations but have never been formally applied to patient selection for destination therapy left ventricular assist device (LVAD). Patient...
