The demand for data transmission is rising expensively the applications of biomedical sensors data, multimedia technologies, and ultrahigh-definition online video streaming. Such require larger bandwidth with minimum latency seamless service delivery. Radio-over-fiber (RoF), integrated wavelength division multiplexing (WDM) technology, being considered one promising technologies. However, integration optical fiber wireless communication also generates non-linear effects as when number users...
Coping up with the rising bandwidth demands for 5G ultra-high speed applications, utilizing millimeter (MM) wave spectrum data transmission over radio a fiber-based system is ideal approach. In this study, highly conversant and spectrally pure photonic generation of 16-tupled MM signal using series-connected DD-MZM lower modulation index, splitting ratio, wider tunable range presented. A 160-GHz generated through double sideband optical carrier suppression technique having an ratio (OSSR) 69...
Cost and complexity are two important parameters that taken into account while generating transmitting MM waves for 5G network. Generating in optical domain using up-conversion techniques eliminates the requirement of high frequency local oscillator (LO) at central station (CS). This paper reports performance 80 GHz wave signal generated from 5 RF along fiber. However, transmission signals through fiber undergoes dispersion which could be reduced by modulating data on single sideband (SSB)...
A centimeter-scale hybrid plasmonic waveguide (HPW) structure based on a grating is proposed at telecom wavelengths. The high-contrast formed by Si and air placed in an slot created the high-index region for attaining nanoscale optical confinement. High-contrast gratings help enhance propagation length up to 3.6 cm with very low loss of 0.11 dB/mm. Further, extremely large figure merit 1,129,623 (>107) confinement 0.00081/μm2 introduced. In present work, finite-element-method-based COMSOL...
The aim of this paper is to present a UK-based consensus principles and recommendations guide rheumatology US training practice.A Delphi process was conducted involving 19 experts representing each the 14 regions UK. A working group experienced British Society for Rheumatology Ultrasound Special Interest Group (BSRUSSIG) members made seven proposals that were presented whole further discussion. This resulted in minor modifications preliminary recommendations. Members then asked anonymously...
With the evolution of cellular network generations to offer higher data rate users, 5G aims a capacity up 10Gbps. This puts an additional impetus for backbone networks be able carry large volume at aggregation points using optical fiber communication network. The voluminous transportation should achieved longer link length with optimum Quality Service. We have proposed and evaluated Optical Fiber Communication (OFC) based on Polarization Division Multiplexing (PDM) in conjunction Hybrid...
Vehicle identification or classification is one of the application areas that come under real time image processing.Vehicle recognition having significance in various applications including traffic monitoring, load number plate recognition, vehicle theft prevention, violation detection, management etc.As images are captured as primary data source, it can have associated impurities which include background inclusion, object overlapping etc.Because this, detection and always a challenge...
BACKGROUNDObstetric haemorrhage due to uterine atony has been the major complication during elective caesarean section.Oxytocin either bolus and/ or infusion drug of choice reduce incidence peripartum because less side-effects compared other uterotonic drugs like methylergometrine.On literature search, we found that different doses oxytocin ranging from 0.3 20 IU have used by various researchers.Low were associated with inadequate effect, whereas higher be serious haemodynamic side...
Adhoc Wireless Sensor Networks (AWSN’s) have found an increasing utility in various applications. In AWSN, sensor nodes are arranged a topology which is suitable to the requirement of nature task. As sensors not connected fixed manner, their networking, location and functioning keeps on changing based situation due these called networks. The biggest challenge keep working for longer life by conserving energy. Therefore, routing protocol needs be selected meet energy conservation at different...
Engineering education plays a pivotal role in the development of technologies, society, nation, economy and employment.It is well evident that information age, technology developing very fast correspondingly demand for highly skilled qualified professionals also increasing.One most critical issues engineering handling placement young technocrats from an industrial perspective to prepare required workforce 21 st century.The trajectory Electronics (EE) has intersected every walk human life.The...
Vertical cavity surface emitting laser (VCSEL) plays a vital role in optical network. The present investigation reports the performance comparison of modeling single-mode VCSELs at room temperature for continuous wave operation. VCSEL study consists InGaAsP-based or active region sandwiched between GaAs/AlGaAs top mirror and GaAs/AlAs bottom mirrors with aim increasing power conversion efficiency (PCE), lasing power, decreasing threshold current. It is observed that lower diameter are most...
Background: Current Rheumatological training for junior doctors in UK is variable during medical school and limited at SpR level. Aiming to assess students exposure Rheumatology their perception of rheumatology FY1 FY2 level, an online survey was conducted which designed distributed via www.surveymonkey.com all (31) schools through e-mail educational directors. Methods: The questionnaire addressed 4th, 5th 6th (where existed) year had 10 questions; 5 questions were related demographics...
Vertical cavity surface emitting laser (VCSEL) is an important source for their evident plentiful applications in optical communication. The present investigation reports a comparison of the modeling and optimization long wavelengths 1310 nm 1550 high speed short VCSEL continuous wave operation at various temperature (283-3230K) diameters. lasing demonstrated device diameter from 2 to 5 μm with threshold current 1.07-1.33 mA power consumption 1.86-2.57 mW 0.94-1.24 1.67-2.1 VCSEL. results...
