We present a new iterative mathematical model for calculating the average bandwidth assigned to traffic flows using a Weighted Round Robin with Priority queuing (WRRPQ) scheduler with both strict and rate controlled priority in IP based NGN networks. The bandwidth assignment estimation is based on the average packet length, link speed and the arrival rate. We prove the model outcome with exampl...

Classically, information theorists have understood the tradeoff between delay and system error performance by using block-length as a proxy. Although this turns out to be correct when feedback is absent, it is shown to be very misleading when feedback is available. For symmetric channels, fixed block-length communication systems show no improvements in their error exponents while fixed delay sy...

The Integrated Optics has resulted in miniaturization of optical devices. Bent waveguides have replaced straight waveguides in optical integrated circuits for such reasons. In the proposed work, curved/bent waveguide is basic structure for generating delay and hence the phase shift. A differential phase shift is obtained by the differential length change between the straight waveguide and a S-b...

OBJECTIVES Delayed discharges are a significant problem for the National Health Service. The objectives of this study were to determine the prevalence and impact of delayed discharge at a single specialist vascular surgery ward. DESIGN A cross-sectional observational study. SETTING A single specialist vascular unit in the UK during a 4-month study period (01/09/2014-31/12/2014). PARTICIPA...

introduction: timeliness has been considered as a key domain in quality of emergency department (ed) care and delay in care providing is influential determinants of patient’s outcomes. the present study, aimed to evaluate the determinants of prolonged ed length of stay (los). methods: in this cross-sectional study, using adopted version of the latest form for external evaluation and accreditati...

Abstract Introduction We investigated patients with acute urinary tract obstruction in a DGH to ascertain which factors predispose CKD and mortality. Method Over five months there were 37 nephrostomy/stent cases, 18 female, 3 mortalities. Median age was 55.5 (18-93). Retrospective data used multiple regression analysis. Input variables included the intervention indication, admission Creatinine,...

We propose a segment delay fault model to represent any general delay defect ranging from a spot defect to a distributed defect. The segment length, L, is a parameter that can be chosen based on available statistics about the types of manufacturing defects. Once L is chosen, the fault list contains all segments of length L and paths whose entire lengths are less than L. Both rising and falling ...
