MRR

Proceedings of the International Conference on Web Intelligence, 2017
The automatic detection of relevant reviews plays a major role in tasks such as opinion summarization, opinion-based recommendation, and opinion retrieval. Supervised approaches for ranking reviews by relevance rely on the existence of a significant, domain-dependent training data set.

FM-MRR Analog Audio System

SPIE Proceedings, 2005
In this work, we describe a hybrid free-space infrared communications link that supports audio transmission. The technique combines conventional frequency modulation (FM) techniques with optical amplitude modulation (AM) with a Multiple Quantum Well (MQW) Modulating Retroreflector (MRR) technology.

Activation of the Salmonella Typhimurium Mrr protein

Biochemical and Biophysical Research Communications, 2008
The Mrr protein of Escherichia coli K12 is a cryptic type IV restriction endonuclease with specificity for methylated DNA. Recently it was discovered that endogenous activation of E. coli Mrr could be triggered by high pressure stress, resulting in the generation of double strand breaks in the host chromosome and concomitant induction of the SOS ...

Modified Round Robin algorithm (MRR)

2017 IEEE International Conference on Power, Control, Signals and Instrumentation Engineering (ICPCSI), 2017
CPU Scheduling Algorithms form the basic and fundamental concepts of Operating Systems. A scheduling algorithm is used to produce effective switches between the processes present in the ready queue. Round Robin algorithm is one among the many CPU scheduling algorithms where every process executes for a given time quantum (TQ).

Photonic Vector Modulator Based on MRR Weight Banks

Conference on Lasers and Electro-Optics, 2022
A microwave photonic phase shifter is presented based on a complex Cartesian weighting approach using microring resonators. The proposed architecture realizes simultaneous phase shifting and combining of RF signals using wavelength-division-multiplexed optical signals.

MRR Systems and Soliton Communication

2015
The nonlinear Schrodinger equation (NLSE) is an appropriate equation for describing the propagation of light in optical fibers. The optical solitons are very stable against perturbations, where it is property of a fundamental soliton makes it an ideal candidate for optical communications. To have the secured communication, the performance of resonators

Solitonic Signals Generation and Transmission Using MRR

2015
The advantage of the study is that nonlinear behavior of light inside ring resonators system can be controlled and managed by using appropriate parameters of the microring resonator (MRR) system. The effects of the coupling coefficients on the bifurcation and chaos behaviors, in terms of roundtrip and output powers are presented.

THz frequency generation using MRRs for THz imaging

2012 International Conference on Enabling Science and Nanotechnology, 2012
We propose a new design of THz frequency carrier generation for medical applications. The dense wavelength division multiplexing can be generated by using a Gaussian pulse propagating within a modified PANDA ring resonator and Add/drop filter. Results obtained have shown that region of frequency can be obtained between 30–100 THz.

Design of ROADM based on CWDM and MRRs

2017 IEEE 2nd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2017
In metro-access optical network, reconfigurable optical add/drop multiplexers (ROADMs) are required. A ROADM based on coarse wavelength division multiplexer (CWDM) and microring resonators (MRRs) has been proposed and demonstrated. The simulation and performance analysis of ROADM system are carried out by using beam propagation method (BPM) and finite ...

Suggesting a Sonographic Index to Measure Ultrasound Diaphragmatic MRR

2016
Measurements of ultrasound diaphragmatic motion may provide important and essential information about diaphragmatic fatigue. In this work, we propose a semi-automated analysis system for measuring the diaphragmatic motion and estimation of the maximum relaxation rate (MRR) from ultrasound M-mode images of the diaphragmatic muscle.
