In this article, we study a first order irreversible exothermic reaction under nonisothermal condition. It is one of the simplest systems capable of showing complex behaviour like multistability, oscillations and hysteresis. We have investigated this system in the presence of external drive and noise in the region where the system shows bistability. We demonstrate the phenomenon of stochastic resonance...
A wideband low noise amplifier is suitable for an emerging architecture such as a SDR and Digital RF. The gallium arsenide process has an advantage of very low noise figure at very high frequency. In this article we have taken efforts to propose a new concept for a wideband highly linear low noise amplifier. The simulations are carried out using Agilent Advanced Design System ADS to analyze the behavior...
The growth of kidney disease has gradually increased over the coming years. Ultrasound imaging is an incontestable vital tool for diagnosis, it provides the internal structure of the body to detect eventually diseases or abnormal tissues non-invasively. This paper presents analysis of Ultrasonography (USG) images for detection of Chronic Kidney Disease(CKD) stages. The methodology of image processing...
In this article, we present an overview of theory and technique for optimal control of molecular dynamics using tailored light fields. The goal of this research is to design an optical field, which can drive a system to a desired target state with a fairly high probability and low power expenditure. For the laboratory implementation of the designed field, it is desirable that it has simple frequency...
In a spacecraft, the Electro Explosive Devices (EED) are used for the appendages deployment activities like Antennas Deployment, Solar arrays deployment etc. EED electronics package provides the required excitation to fire the SQUIB. During the launch phase, the spacecraft experiences a high level of Electromagnetic (EM) radiation. The EEDs should not get enabled due to the EM radiation. EMC analysis...
Experimental and simulation results of high-frequency channel noise in MOSFETs with 40-, 80-, and 110- nm gate lengths are presented. The measured dc – characteristics can be matched using the drift–diffusion (DD) and hydrodynamic (HD) transport models, both incorporating velocity saturation. The DD model grossly underestimates the measured noise, demonstrating the inadequacy of channel-length modulation...
License plate recognition (LPR) is a technology that enables computer systems to read automatically the registration number (license number) of vehicles from digital pictures. This paper deals with the recognition of Indian car license plate recognition. The LPR system consists of four steps Plate Localization, Preprocessing, Segmentation and Normalization and Optical Character Recognition (OCR)....
