On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(2017-07-07)
We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chi-squared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ...
Study On DC-Link Capacitor Current In A Three-Level Neutral-Point Clamped Inverter
(2017-05-24)
Three-level diode-clamped inverter is being widely used these days. Extensive research has been carried out on pulse width modulation (PWM) strategies for a three-level inverter. The most widely used PWM strategies are ...
Multiview Face Detection And Free Form Face Recognition For Surveillance
(2014-10-15)
The problem of face detection and recognition within a given database has become one of the important problems in computer vision. A simple approach for Face Detection in video is to run a learning based face detector every ...
Motion Estimation From Moments Of Projection Data For Dynamic CT
(2016-09-15)
In X-ray computed tomography, motion of the object (breathing, for example)
while X-ray projections are acquired for tomographic reconstruction leads to mo-
tion artifacts in the reconstructed image. Object motion (such ...
Dimensioning Of Corona Control Rings For EHV/UHV Line Hardware And Substations
(2015-07-13)
High voltage (EHV and UHV) transmission facilitates transfer of large amount of power over long distances. However, due to the inherent geometry, the line and substation hardware of EHV and UHV class generate high electric ...
DeNOx Studies In Diesel Exhaust Under AC/Pulse Energizations
(2015-11-16)
It is the need of the hour to reduce the pollutants which poison our atmosphere and harm our health. The diesel engines are the most efficient IC engines in the world today, but paradoxically, they are also the engines ...
Modular Design Of Microheaters, Signal Conditioning ASIC And ZnO Transducer For Gas Sensor System Platform
(2013-07-16)
With the proliferation of industries world-wide, there is a growing need and interest in sensing and monitoring environmental pollutants and monitoring the concentration of chemicals/gases in industrial process control. ...
Atomistic Study of Carrier Transmission in Hetero-phase MoS2 Structures
(2018-05-25)
In recent years, the use of first-principles based atomistic modeling technique has become extremely popular to gain better insights on the various locally modulated electronic properties of nano materials and structures. ...
Power Efficient Last Level Cache For Chip Multiprocessors
(2015-09-09)
The number of processor cores and on-chip cache size has been increasing on chip multiprocessors (CMPs). As a result, leakage power dissipated in the on-chip cache has become very significant. We explore various techniques ...
Dead-Time Induced Oscillations in Voltage Source Inverter-Fed Induction Motor Drives
(2017-12-07)
The inverter dead-time is integral to the safety of a voltage source inverter (VSI). Dead-time is introduced between the complementary gating signals of the top and bottom switches in each VSI leg to prevent shoot-through ...
