A reliable multilevel inverter with fault tolerance is proposed. It consists of two sources and six switches. The unipolarity voltage level produced by the proposed inverter is transformed to dual polarity with the help of H-bridge. The proposed inverter produces maximum 9 levels output voltage with asymmetrical source and 5 levels output voltage with symmetrical source in healthy condition. During...
We demonstrate index and temperature microsensing at picoliter liquid sample volume using hundreds-micron-scale fiber Michelson interferometer with multiple small foci in space. The index and temperature sensitivity can reach 59.4 nm/RIU and 23 pm/°, respectively.
We present deterministic fabrication of a two-dimensional lattice of quantum emitters in an atomically thin semiconductor. Resonant laser spectroscopy of these emitters reveals localized exciton states that exhibit stable, bright and high-purity single photon emission.
This paper presents a Cylindrical GAA TFET based on germanium source for low power applications. The proposed device used the merits of low band gap material such as germanium, which is used as a material in the source region. Device investigations have been made in terms of DC characteristics like ION, IOFF, SS, ION/IOFF. The proposed device increases ON-current as high as 1.9 × 10−5 A/μm, which...
In this paper, we study the source drain Gaussian doping profile of strained In0.53Ga0.47AS based high electron mobility FinFET transistor (HEMT). The Gaussian doping profile is created using Pearson distribution model by setting the values of the gamma and beta parameters (the function characterizing the amorphous part of the profile). The ON current increases exponentially and the step doping also...
This paper presents a novel subthreshold Darlington pair based negative bias temperature instability (NBTI) monitoring sensor under the stress conditions. The Darlington pair used in the circuit provides the stability of the circuit and the high input impedance of the circuit makes it less affected by the PVT variations. The proposed sensor provides the high degree of linearity and sensitivity under...
Uninterruptible Power Supplies (UPS) have several closed loop control topologies for control of Voltage Source Inverter (VSI). The topologies vary mainly due to choice of control/feedback variable. This paper attempts to categorize different control topologies and highlights the similarities/differences between them. Further, an analytical study on the basis of steady-state and transient performance,...
Vehicle to Grid (V2G) is the concept of connecting a group of electric vehicles (EV) to the grid for power transaction. EVs can be connected to the grid through the home interface or through the chargers available at charging stations. In this paper, a single phase on-board charger with low complexity control scheme is proposed for EV power transaction. The power flow from and to the grid is processed...
Support Vector Machines (SVM) are considered as one of the most commonly used pattern recognition techniques for various applications. In this paper, a novel attempt is made to design and implement SVM classifier using Reconfigurable architecture on a Xilinx Virtex-5 FPGA. The performance of proposed reconfigurable system is compared with its conventional non-reconfigurable architecture and the results...
The indirect B'lood pressure measurement includes devices like Sphygmomanometer, pressure Cuff and hand pump. The Sphygmomanometer is shown in the Fig.-1. The Physicians is used to measure the blood Pressure by using Pneumatic Cuff encircling the upper arm of the patient usually. An inflatable section of this Cuff is inflated by a small hand pump and the pressure in the system is indicated by a mechanical...
The study in this article focuses on chattering free higher order sliding mode control (HOSMC) and continuous time event triggered higher order sliding mode control (ET-HOSMC) for nonlinear uncertain systems. Conventional sliding mode control is affected by high-frequency oscillation in the control signal known as chattering. Chattering in the control signal overshadows the main advantages of sliding...
Smoking is one of the most challenging behavioral health problems. In the past, failed quit attempts have been attributed to factors including stress, presence of smoking cues, and negative affect – most of which were self-reported and prone to recall-bias. The first step in designing effective smoking cessation systems is to objectively identify factors that contribute to lapse. In our research,...
Component-based software development is one of the proficient models of constructing eminent-quality software products. Reusability is the basic concept behind the component-based software. Reusability suggests re-use of existing software artifacts rather than developing them from the beginning. Components interact to share services and information in component-based software environment. In this...
Development of depth sensors paves way for implementation of touch-less biometric authentication systems using 3D gestures or signatures. No keys or passwords are required in such systems to prove identities. Moreover, the systems do not suffer from various security risks such as stolen passwords or loss of passwords. In this paper, we propose such a security system that is robust in nature by allowing...
A sign language is generally composed of three main parts, namely manual signas that are gestures made by hand or fingers movements, non-manual signs such as facial expressions or body postures, and finger-spelling where words are spelt out using gestures by the signers to convey the meaning. In literature, researchers have proposed various Sign Language Recognition (SLR) systems by focusing only...
In this paper, analytical and simulation based analysis to verify the inherent properties of SiGe HBT is done. The major performance parameters of SiGe HBT are cut-off freuency fT, maximum oscillation frequency fmax, base transit time τb, current gain β and electron mobility μn of SiGe base. These performance parameters are responsible for the reliability of SiGe HBT. Temperature is one of the major...
Leakage power is a major issue of concern in Deep Sub-Micron (DSM) and Ultra Deep Sub-micron technology (UDSM) in CMOS circuit design. LECTOR-EP (LECTOR technique with extra PMOS), LECTOR-EN (LECTOR technique with extra NMOS) and Double LECTOR techniques have been proposed in this paper to reduce the leakage. Due to increase in resistance for the path from Vdd to ground, substantial reduction in leakage...
The performance of a conventional machine learning the model trained on a source domain degrades poorly when they are tested on a different data distribution (target domain). These traditional models deal with this problem by training a new paradigm for the particular different data distribution (target domain). Therefore, training of a new paradigm forthe individual data distribution is computationally...
Volume estimates of metric balls in manifolds find diverse applications in various applied sciences including information theory and coding theory. In this paper, the focus is on the exact volume of metric balls in real Grassmann manifold, extending recent results of the complex case. Firstly, we formulate the exact volume as a multi-dimensional integral, which is then represented as an inverse Laplace...
The design of hybrid boosting converter has gained significant advantage of voltage regulation from its boost structure by the gain enhancement from its voltage multiplier structure. Many works are reported for the design of hybrid boost converter which consists of single switch, single inductor by employing bipolar voltage multiplier.
