In this paper, an innovation based adaptive estimation Kalman filter (IAE-AKF) with double transitive factors is proposed for denoising the fiber optic gyroscope (FOG) signal. In this algorithm, double transitive adaptive factors are described in two stages. The transitive factor is introduced into the predicted state vector equation in stage one, where as in second stage, adaptive factor is scaled with measurement noise covariance matrix (R). These adaptive factors are developed based on the innovation sequence in adaptive Kalman filter. The predicted state error and measurement noise covariance matrix are updated by the double transitive adaptive factor in the process of iteration in stage one and two respectively. This algorithms is applied for denoising FOG signal in both static and dynamic conditions. The performance of proposed algorithm is compared with Conventional Kalman filter (CKF) and AKF with transitive factor. The precision improvement of FOG is calculated by variance and standard deviation, the predicted results revealed that the proposed algorithm is an efficient algorithm in drift denoising of FOG signal. In dynamic condition, the mean squared error (MSE) and root MSE (RMSE) values are calculated before and after denoising of FOG signal using proposed algorithm.

Process, voltage and temperature (PVT) variations in emerging ultra-deep submicron (UDSM) technology nodes critically affect device performances and limit further scaling of such devices based on Moore's law. This paper proposes CNFET-based design of robust Schmitt trigger circuits, which outperform their CMOS counterparts in terms of mean values as well as variabilities of all considered design metrics. Popular Schmitt trigger designs are investigated and a comparative analysis is carried out based on Monte Carlo simulations in an HSPICE environment, using the 16-nm CMOS Predictive Technology Model (PTM), to choose the designs with best performance in terms of variability of design metrics such as power, power-delay product (PDP) and hysteresis width. These are then re-designed with corresponding optimized devices using the experimentally validated Stanford University CNFET model. The proposed CNFET-based circuits provide a 9.9×, 11.8× and 22× improvement in power, PDP and hysteresis width variability respectively, while also providing better noise immunity through increased hysteresis widths, thus demonstrating their superiority to CMOS circuits in all respects at highly scaled technology nodes.

In this paper, a CSD (Current Synchronous Detection) based control of a grid interfaced SPV (Solar Photovoltaic) power generating system is proposed with an improved power quality at ac mains. A two-stage SPV based grid interfaced three-phase four-leg VSC (Voltage Source Converter) based system is designed and modeled in order to achieve the compensation of reactive power for ZVR (Zero Voltage Regulation) or for PFC (Power Factor Correction) along with load balancing, elimination of load harmonics currents and mitigation of neutral current at the PCC in a four-wire distribution system. The performance of SPV generating system is simulated using MATLAB/simulink and sim-power system.

That storage devices like batteries can substantially improve performance of power distribution system is well established. These improvement can include attributes like reduction in line loading, reduction in losses, improved voltage profile, better voltage control by minimizing voltage deviations, reactive power and load leveling. The extent of improvement can provide clue to placement of the batteries. In the literature, the placement are generally based on only considering one of these attributes. This paper attempts to take an integrated approach considering simultaneous effect of all the above attributes. The feasible plans are generated by eliminating infeasible plans. Analytical Hierarchy Process (AHP) is used to assign the weights to different attributes. Data Envelop Analysis (DEA) is used to judge the feasible plans on common platform considering normalized values of the attributes. The plans with high efficiency can help in decision on placement in an integrated manner with proper tradeoff of attributes. The proposed methodology is illustrated on a IEEE 14 and 30 bus distribution system.

Cognitive radio (CR) systems need to detect the presence of licensed primary user (PU) reliably. Cooperation among multiple CRs helps to enhance the reliability of detection of the PU in case of unreliable decision by a single CR due to channel uncertainties. In this paper, we consider cooperative spectrum sensing (CSS) based on energy detection in cognitive radio networks (CRN) which uses soft combination of the observed energy values from different CRs. More precisely, we study the performance of CSS with several soft data fusion schemes namely, (a) Square law selection (SLS) (b) Square law combining (SLC) (c) Maximal ratio combining (MRC) that can be implemented at fusion center (FC). The performance of CSS has been assessed under several cases of sensing (S) channels such as AWGN, log-normal shadowing, Rayleigh and Rician fading channels. Comparative performance of CSS for various soft data fusion schemes under different fading channels has been studied for various values of average S-channel SNRs, time-bandwidth products, different number of CRs. The impact of shadowing and fading parameters on missed detection performance of CSS is indicated. Further, the performance comparison between soft data fusion schemes and hard decision fusion schemes is also highlighted.

In this paper, electron energies of a heterostructure quantum disk with cylindrical geometry is numerically computed considering both parabolic and nonparabolic band structure in presence of electric field applied along the axis. Time-independent Schrödinger equation is solved with appropriate boundary conditions, and first and second-order Bessel functions are considered for computation of energy subbands. Three lowest confinement states are plotted with radius and thickness, independently considering Al0.3Ga0.7As as an example. Results obtained by changing dimensions and applying external electric field have significant effect on optical tailoring of quantum disk.

SCADA (Supervisory Control and Data Acquisition) is a type of industrial control system. In typical industrial automation applications, PLCs are used to communicate between the plant and SCADA. In this paper we are using a low cost microcontroller to understand the various control techniques and capabilities of SCADA and implement them in real time. A simple temperature control scheme is developed using ATMEGA2560 microcontroller and industry standard SCADA software Vijeo Citect v7.2. We make use of MODBUS ASCII protocol which is an industry standard communication protocol to set up a temperature control system which collects real time temperature data, processes the data and performs the desired control action. Major contribution of the paper is in developing MODBUS library for communication between microcontroller and SCADA and implementing control algorithms such as ON/OFF and proportional controller on data obtained in real time. Thus this paper presents a low cost automation scheme which can be easily extended for more complicated control schemes including wireless control. The project has been developed as first step towards a project on pipeline leakage detection scheme using wireless sensor nodes.

Spatial image resolution explains about the pixel density in a digital image. As a result more the number of pixels more detailed visibility of information contained in the image. Hardware limitations restrict the increase in number of sensor elements per unit area in camera. Therefore an imaging system with inadequate sensor array will generate low resolution image which causes pixelization effect in them. This problem is solved in software level using signal processing techniques called super resolution based image reconstruction. In this paper super resolution based image reconstruction problem is addressed, which is used for resolution enhancement. Unlike interpolation, it takes information from multiple number of low resolution images with sub-pixel shifts and contain nonredundant data to generate a high resolution image. In this proposed reconstruction method, a hybrid iterative back projection technique is developed exploiting the notion of cuckoo search optimization algorithm in iterative back projection method. The high resolution solution from iterative back projection method is optimized using Cuckoo optimization algorithm. The performance of the proposed algorithm is found to be outperforming that of existing IBP and other interpolation based reconstruction techniques.
