In the essential area of Network Management we have dealt with the subject of the scheduler reaction and adjustment in a dynamic resource environment. Different scheduling models from various areas of Computer Networks (wired and wireless) are presented. Better performance for all the cases via simulation is provided. Many methods of packets? service have been developed, associated with the bor...

Fair Queuing was invented to ensure that every flow gets its fair share of the total bandwidth. Efficient Fair Queuing Using Deficit Round-Robin, DRR, proposed by Shreedhar and Varghese [1], reduces the work to process each packet from O(log(n)) to O(1). DRR was also extended to accommodate latency-critical flows. DRR+ uses a timer to police each latency-critical flow, and was shown to have a l...

Major natural disasters in recent years have had high human and economic costs, and triggered record high postdisaster relief from governments and international donors. Given the current economic situation worldwide, selecting the most effective disaster risk reduction (DRR) measures is critical. This is especially the case for low- and middle-income countries, which have suffered disproportion...

BACKGROUND At least 14 stratifiers exist to assess recurrence risk, chemotherapy response, and overall survival (OS) in women with early-stage breast cancer (ESBC). These stratifiers have not been compared using a recently developed rigorous framework. We performed a systematic review of the literature on clinical validity/utility, change in clinical practice, and economic implications of ESBC ...

In multi-service packet networks the packet scheduling algorithm plays a key role in delivering guaranteed service to different flows. In this article we evaluate surplus round robin (SRR) scheduling algorithm. We apply the Latency-Rate (LR) servers theory in order to obtain bounds on the latency and delay provided by the algorithm. We compare the performance characteristics of SRR with the pop...

The gene for human involucrin (hINV) is selectively expressed in stratifying epithelial cells lining external body surfaces. Previously, we characterized the hINV promoter 5' distal regulatory region (DRR) located between nt -2473 and -2088 upstream of the transcription start site. This region is required for optimal hINV gene expression. The DRR contains weak and strong activator elements. The...

Both physicians and consultant pharmacists have a longstanding role in nursing home care. The physician role was emphasized in 1974, when medical directors were required in all skilled nursing facilities. It was intensified in 1987, when the Omnibus Budget Reconciliation Act of 1987 (OBRA '87) regulations required all nursing facilities to have a medical director and reinforced that each reside...

The emerging high-speed broadband packetswitched networks are expected to simultaneously support a variety of services with different Quality-of-Service (QoS) requirements over the same physical infrastructure. Fair packet scheduling algorithms used in switches and routers play a critical role in providing these QoS guarantees. Deficit Round Robin (DRR), a popular fair scheduling discipline, is...

We evaluate the accuracy of direct-to-reverberation energy ratio (DRR) estimation that uses the direct sound to reverberation spatial correlation matrix model (DRSC model). The DRSC model, which expresses the spatial correlation matrix with two different matrices of direct sound and reverberation, assumes that the direct sound propagates only from the direction of the sound source but that the ...

BACKGROUND The Third UN World Conference on Disaster Risk Reduction recommended the implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030, which aims to achieve substantial risk reduction and to avoid various disaster-associated losses, including human lives and livelihoods, based on the lessons from the implementation of the Hyogo framework. However, the recommendations ...
