For effective communication between two humans, one needs to understand the emotional state of its fellow beings. Predicting human emotion involves several factors, which include, but not limited to, facial expression. Many researches in this direction are based on features extracted from facial expressions. In this paper we are proposing a model, which can predict human emotion by considering facial as well as context information. Our model not only extracts features from facial expressions but also is aware of the background context in the image dataset. We have shown the relevance of contextual information with facial expression and its impact on the predicted results. Our model captures facial expressions and contextual information with the most relevant part boosted up to capture feature and utilize it to predict human expressions. We are using Attention model in our architecture to boost relevant part, and learn what to boost to make relevant prediction. We have performed several experiments and compare the relevance of facial expressions with context and context free environments. Our proposed model is robust, capable of predicting emotions in real time with improved accuracy of 8% over state of the art accuracy to the best of our knowledge. In addition, it is implemented over dataset, which contains mostly spontaneous images and not posed one, leading to improved results.

Depth estimation from a single RGB image has been one of the most important research topics in recent days as it has several important applications in self-supervised driving in autonomous cars, image reconstruction, and scene segmentation. Depth estimation from a single monocular image has been challenging as compared to stereo images due to the lack of spatio-temporal features per frame that makes 3D depth perception easier. Existing models and solutions in monocular depth estimation often resulted in low resolution and blurry depth maps and often fail to identify small object boundaries. In this paper, we propose a simple encoder-decoder based network that can predict high-quality depth images from single RGB images using transfer learning. We have utilized important features extracted from pre-trained networks, and after initializing the encoder with fine-tuning and important augmentation strategies, the network decoder part computes the high-end depth maps. The network has fewer trainable parameters and small iterations, though it outperforms the existing state-of-the-art methods and captures accurate boundaries when evaluated on two standard datasets, KITTI, and NYU Depth V2.

This paper is inspired by the question “how novel quasi six-phase doubly-fed induction generator (QSPDFIG) will behave if it is modelled into multiple reference frames?”. Due to the attractive success of the multiphase system into power transmission, generation and drives, the interest of research fraternity is also shifting toward the wind energy conversion system (WECS) based QSPDFIG. Hence, this paper introduces the concept of novel QSPDFIG through modeling and simulation. To strengthen the concept of QSPDFIG the proposed machine is modelled into multiple reference frames (the rotating reference frame (RRF), stationary reference frame (SRF), synchronous reference frame (SyRF)). Moreover, the performance of this novel machine is verified through simulation results into RRF, SRF, SyRF. In addition to modeling and simulation, this paper also illustrates the advantages, utility, and future scope, for the research fraternity.

Electric supply utilities invest a lot of money every year to improve the quality of power supplied to their customers. With the increase in demand day by day, an oligopoly has been created in the market to maintain a certain level of reliability to attract the customers such that they show the willingness to pay more for a more reliable system. For enhancing the customer contentment and comfort, according to their insistence, improvement of service reliability and simultaneously minimizing the capital costs is an extensive issue for the optimization of the distribution system. The reliability of the distribution system may be improved by the optimal placement of protective devices and switches but the determination of the optimal location and number of switches is a major concern from the reliability and economic outlook. In this paper, manual as well as optimal placement of reclosers have been done in a 13-bus radial distribution system to maximize the net profit to the utility by improving the system reliability. For optimal placement of reclosers, genetic algorithm (GA) technique has been utilized. Reliability indices such as- SAIFI, SAIDI, CAIDI, ASAI, ASUI & AENS before and after the placement of reclosers have been compared. The results thus obtained show that maximum profit to the utility with minimum capital and outage costs can be obtained by the optimal placement of reclosers in a radial distribution system.

Power dissipation becomes an essential criterion in VLSI system in the current ultra-low power applications scenario. Sub-threshold adiabatic logic designing has shown its potential as more efficient logic for ultra low energy-consuming circuits. Parity generator and parity checker are important combination circuit for error-free transmission of data. Both of these circuits are widely used for communication to encode the data. These circuits are realized using sub-threshold adiabatic logic (SAL) by deploying CADENCE 45nm technology. Extensive simulation study has been carried out to validate the mathematical expressions. Our study validates the enhanced circuit performance using sub-threshold adiabatic logic. The present work will facilitate researchers for circuit realization for energy applications.

In this work, we propose a two-stage autoencoder based compressor-decompressor framework for compressing malaria RBC cell image patches. We know that the medical images used for disease diagnosis are around multiple gigabytes size, which is quite huge. The proposed residual-based dual autoencoder network is trained to extract the unique features which are then used to reconstruct the original image through the decompressor module. The two latent space representations (first for the original image and second for the residual image) are used to rebuild the final original image. Color-SSIM has been exclusively used to check the quality of the chrominance part of the cell images after decompression. The empirical results indicate that the proposed work outperformed other neural network related compression technique for medical images by approximately 35%, 10% and 5% in PSNR, Color SSIM and MS-SSIM respectively. The algorithm exhibits a significant improvement in bit savings of 76%, 78%, 75% & 74% over JPEG-LS, JP2K-LM, CALIC and recent neural network approach respectively, making it a good compression-decompression technique.

The conventional overcurrent relay used in the microgrid system is unable to detect high impedance fault. The magnitude of fault current is very less or same as the normal load current during high impedance fault and thus relay finds difficulty in detecting the fault. In the proposed method, the wavelet decomposition approach is applied to extract the order of higher frequency component present in the instantaneous current signal. The db4 mother wavelet is used to decompose the current signal and the third decomposed level is used to estimate the Teager Kaiser Energy Operator. The energy operator is consistently zero for no-fault and normal power system operating conditions, but rise significantly with the initiation of high impedance fault. The proposed is tested for different values of fault resistance, capacitor charging and nonlinear load switching conditions. The modified IEEE 13 bus distribution system integrated with hybrid distributed generators is considered for simulation analysis. The performance of the proposed HIF detection technique is compared with other existing techniques. The results prove the efficacy of the proposed integrated approach.
