In this paper, effects of the structural parameters on the optical characteristics of an add-drop filter, consisting of two straight waveguides and a micro-ring resonator (MRR), have been investigated. In this research, effects of MRR radius, the width of MRR and waveguide and the gap between MRR and waveguide, on free spectral range (FSR) and coupling coefficient have been studied. It is found...

Purpose: The current study aims to provide normative data for the maximum repetition rate (MRR) development of Dutch-speaking children based on a large cross-sectional using standardised protocol.Method: A group 1014 typically developing aged 3;0 6;11 years performed MRR task Computer Articulation Instrument (CAI). number syllables per second was calculated mono-, bi-, and trisyllabic sequences...

BACKGROUND Although excessive alcohol-related mortality in the post-Soviet countries remains the major public health threat, determinants of this phenomenon are still poorly understood. AIMS We assess simultaneously individual- and area-level factors associated with an elevated risk of alcohol-related mortality among Lithuanian males aged 30-64. METHODS Our analysis is based on a census-lin...

Modulating retro-reflectors (MRR) couple passive optical retro-reflectors with electro-optic modulators to allow free-space optical communication with a laser and pointing/acquisition/tracking system required on only one end of the link. In operation a conventional free space optical communications terminal, the interrogator, is used on one end of the link to illuminate the MRR on the other end...

The operating control parameters of injection flushing type of electrical discharge machining process on stainless steel 304 workpiece with copper tools are being optimized according to its individual machining characteristic i.e. material removal rate (MRR). Lower MRR during EDM machining process may decrease its’ machining productivity. Hence, the quality characteristic for MRR is set to high...

In chemical mechanical planarization, abrasive particles are pushed onto a wafer by a deformable pad. In addition to the pad–particle contact force, surface forces also act between the wafer and the particles. Experimental studies indicate the significance of slurry pH and particle size on the material removal rate MRR . In this work, a model for MRR, including the contact mechanics of multiple...

Background Three randomized trials (RCTs) in low-weight (<2.5 kg) infants have shown that Bacille Calmette-Guérin (BCG) vaccine nonspecifically reduces all-cause mortality in the neonatal period. Methods Using data from 3 RCTs of early BCG (n = 6583) we examined potential sex differences in the timing of the mortality reduction in the neonatal period, presenting metaestimates of the main outc...

OBJECTIVE The purpose of this study was to evaluate split renal function, estimate single-kidney renal function, and identify cause of obstruction in patients with ureteropelvic junction (UPJ) obstruction by using contrast-enhanced dynamic MR renography (MRR). MATERIALS AND METHODS Seventeen patients with UPJ obstruction underwent MRR and diuresis nuclear renography. Nuclear renography assess...

Job scheduling in data grids must consider not only computation loads at each grid node but also the distributions of data required by each job. Furthermore, recent trends in grid applications emphasize high throughput more than high performance. In this paper, we propose a centralized scheduling scheme, which uses a scheduling heuristic called Maximum Residual Resource (MRR) that targets high ...
