Previous works in IEEE 802.16e power saving mainly focused on standard Type I or Type II power saving class. The limitation of adopting Type I or Type II was discussed in our previous work, and the idea of applying traffic modeling and measurement called Load-Based Power Saving (LBPS) was proposed. The base station in LBPS measures the traffic load and estimates the sleep window size for mobile...

This memo contains various protocol identifier examples, which can be used to produce valid protocolDirTable INDEX encodings, as defined by the Remote Network Monitoring MIB (Management Information Base) Version 2 [RFC2021] and the RMON Protocol Identifier Reference [RFC2895]. This document contains protocol identifier macros for well-known protocols. A conformant implementation of the RMON-2 M...

Medium access control (MAC) protocols in a cognitive radio network (CRN) are required to increase spectral efficiency and achieve high data rate for secondary users (SUs). Many MAC protocols use a single control channel with a bottleneck problem. In this paper, we propose a multichannel MAC protocol using dicontiguous orthogonal frequency division multiplexing (D-OFDM) in a CRN. Since D-OFDM te...

background: recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (gnrha) at beginning of ovarian stimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (ivf) cycles. objective:the efficacy of gnrha stop protocol in poor responder patients in ivf cycles was assessed...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

Information about objects that split or merge is often generated dynamically as a by-product of computation or in the observation of real-world behavior. Visualization tools for such processes must not only reveal temporal patterns and spatial organization but should also accommodate on-the-fly generation of split-merge information. This paper develops a formal structure for split-merge process...

The proposed Loop-free Distance Vector Routing (LFDVR) is a distributed dynamic routing, derived from the famous Bellman Ford’s Distance Vector Routing Algorithm (BFDVRA) which is widely used in the Internet and private intranets. Several routing protocols based on distance-vector algorithms have been proposed like Routing Information Protocol (RIP), Gateway-to-Gateway Protocol (GGP) and Exteri...

We investigate the impossibility of solving certain problems in an unreliable distributed system where multiple processes may fail. We assume undetectable crash failures which means that a process may become faulty at any time during an execution and that no event can happen on a process after it fails. A sufficient condition is provided for the unsolvability of problems in the presence of mult...

SPLIT is a simple prototype Lawful Interception software system which is used to evaluate the viability of using both standard network cards and specialised monitoring hardware for the purpose. Lawful Interception requires reliable packet capture, filtering and protocol analysis on high bandwidth links. While standard NICs can take on these various roles, their performance is only adequate in c...

Background Diffuse myocardial fibrosis may be quantified with cardiovascular magnetic resonance (CMR) by calculating extra-cellular volume (ECV) from native and post-contrast T1 values. Previous studies have used either infusion or single bolus contrast administration. In clinical practice however split dose contrast injection is used as part of a stress/rest protocol in stress perfusion studie...
