Two-stage ignition and NTC phenomenon in diesel sprays is investigated by performing 3-D two-phase reacting flow simulations in a dual-fuel engine. Spray processes modeled include fuel atomization, droplet distortion, droplet drag, turbulent dispersion, droplet interactions in terms of collision and coalescence, vaporization, and spray–wall interaction. A validated reaction mechanism is impleme...

In this paper, we implement a Steinhart-Hart calibration-factor value measurement system to obtain accurate temperature measurements of a negative-temperature coefficient thermistor. The thermistor is mounted on a micro-polymerase chain reaction (PCR) chip in a micro-PCR systemthat requires accurate temperature measurement and control. When obtaining the calibration-factor value, it is impossib...

I am taking this opportunity to introduce myself the readership of IEEE Nanotechnology Magazine as 2022–2023 president IEEE Council (NTC). humbled and honored by trust that NTC leadership has placed in me for next two years. Moreover, proud past accomplishments look forward continuing growth bo...

We report a wideband and polarization-/wide-angle insensitive metamaterial absorber based on symmetry structure associated with surface mount resistors. The proposed consists of periodic array top metal resonator loading four lumped resistors continuous ground plane separated by dielectric substrate FR-4. A prototype the is fabricated measured, confirming good agreement between measurement simu...
