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.

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 ...

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).

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

A 3D Spark Model to Evaluate MRR in ECDM

Journal of Advanced Manufacturing Systems, 2019
Electrochemical discharge machining (ECDM) is an advanced machining process which uses both chemical action and spark discharge method for removal of materials. Till date, most of the applications of ECDM are in machining nonconductive materials, although some authors have also tried machining conductive materials.

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.

Implementation and Evaluation of 79GHz MRR Sensor for Automotive Environments

2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2020
In this paper, we implement and evaluate 79GHz middle range radar for automotive environments. For the purpose, we design and implement antennas, signal processing software and a sensor module. We also evaluate the sensor and analyze the performance in the view of detection range and field of view.

MRR - Material Recovery Right

The building sector accounts for around 37% of global emissions, a doubling of raw material use by 2060, and a projected 70% increase in construction waste by 2050. These challenges highlight the urgency of circular economy solutions in real estate and construction.

Balun and power divider based on multilayer ring resonators (MRR)

2017 IEEE 17th International Conference on Ubiquitous Wireless Broadband (ICUWB), 2017
This paper presents novel super compact microwave power dividers and balun (balanced-to-unbalanced) circuits. The proposed devices are based on multilayer ring resonators (MRR) structure. These new microwave devices are highly compact and flexible in design that can operate within various desirable bandwidths from narrow-band to ultrawideband (UWB ...
