Heart disease are very common in humans because of their life style. It become life threatening when do not treated on time. So the early detection of heart disease has become very important. Many researchers have done a lot of research on the prediction of the heart disease. To minimize the risk of loosing life, we have proposed a Artificial neural network based method that can predict the heart disease in the early stages. The proposed method is tested over the publicly available UCI dataset. We have achieved 96.09% accuracy with the proposed method.

A charger topology using a bridgeless coupled switched inductor configuration is demonstrated in this paper for battery charging of low voltage electric vehicles (LVEVs). In an attempt to obtain wide voltage gain (high step-down gain) between high AC input and low DC output (EVs battery packs), a bridgeless SEPIC topology, with reduced switch and a coupled switched inductor structure is designed, which is able to give good grid side as well as battery side performance. Unlike existing bridgeless configurations, the circulating current through anti-parallel diode of the switch during its non-conduction period is completely eliminated in the presented topology. The coupled switched inductor along with the operation of the inductors in discontinuous inductor current mode (DICM), further helps in decreasing the size of the magnetic components and hence the size of the charger as a whole. In contrary to many of the existing SEPIC high power factor (HPF) AC-DC converter based battery chargers, the topology presented in this work has continuous flow of current both at the input side and output side, thus reducing the need of large filters, as the ripple content is considerably low. The operation of the inductors in DICM, helps in implementing inherent power factor correction, and soft switching for the switches and diodes. Lastly, the design, operating modes, and performance of the charging circuitry are verified through simulation and corresponding results are discussed here for performance verification.

In recent years, compared to traditional supply chain systems Blockchain technology provides countless opportunities and potential to improve and develop the framework in a supply chain management model. We developed a client-side application which acts as a supply chain management platform built using Blockchain technology and Web3-net that provides access to cutting-edge services which include inventory tracking, order placement and product attribute information log. Cryptocurrency transactions are stored on a shared, digital ledger called a blockchain. This decentralized technology is spread across many computers and records every transaction. The platform provides secure and authentic information to its users at all stages using a decentralized app or DAPP which we have developed to ensure a seamless experience for verifying and maintaining data regarding all inventory parts and orders. This paper gives a model demonstration of the implementation of Blockchain Technology at the industry level. However, additional functionalities can be added in the future with enhanced compatibility.

The present investigation shows the application of a modified Johnson converter for battery charging. The modified Johnson converter can provide the voltage gain of either polarity for different duty ratio ranges. Another advantage of this converter is that it can be used for both stepped up and stepped down output voltage. After analyzing the converter in non-ideal modes of operation, the design aspects for the inductor and capacitor were looked into details. A closed-loop controller is developed using various transfer functions. The hardware results of the converter are shown using a DC voltage source and resistive load. The integration of photovoltaic and batteries using a modified Johnson converter is the highlight of the present investigation. For this integration, a PI controller for current reference control is designed. The step up and step down profile of output voltage is used for charging the batteries in series or parallel. Simulation studies show the charging of the batteries of 96V and 12V, while PV is sourcing power at the maximum power point. The hardware result of the studies is in progress.

Deregulation of cyclin-dependent kinase-5 is a hallmark of different neurodegenerative disorders, including Alzheimer's and Parkinson's disease. Herein, we have screened different natural compounds with anticancer properties against cyclin-dependent kinase-5 enzyme. The blood-brain barrier permeability and pharmacokinetic analysis, including various descriptors, screened 27 natural compounds. The docking of candidate compounds identified 3 compounds with good docking energies and stable interactions when compared to the reference drug roscovitine. Further, molecular dynamics simulation analysis including root mean square deviation, root mean square fluctuation, the radius of gyration and binding energies for 50ns revealed two compounds. Overall, we recommend two natural products apigenin and salvianolic acid as candidate inhibitors to target cyclin-dependent kinase-5 for treating Alzheimer's and Parkinson's disease.

Rural development is one of the primary goals in developing nations like India since more than 70 percent of the population lives in rural villages. This paper aims to develop and implement an effective energy management strategy for a stand-alone Amrita Micro-Hydro Power Plant(AMHPP) set up in a remote tribal community in Kerala. The Energy management strategy is implemented by the development of regression-based machine learning models for the prediction of rainfall, thereby deriving the water flow rate and power generation at AMHPP. Five regression-based machine learning models were compared to find the optimal model to increase the asset utilization of the hydro-micro grid system. The performance of prediction models based on daily and monthly data is assessed using the correlation coefficient (R), mean absolute error (MAE), and root mean square error (RMSE). In terms of the various types of regression, including linear, lasso, ridge, XGBoost, and elastic net, the machine learning technique XGBoost regression produced a comparably accurate prediction model. The proposed energy management strategy based on the XGBoost regression model can increase the micro-hydro system's real-time power utilization efficiency w $mathbf{h}$ ile balancing the available hyd $mathbf{r}$ oenergy and load management for the micro-grid system.

The design of an isolated gate driver for a Medium Voltage (MV) Cascaded H-bridge (CHB) converter is proposed in this paper. Isolation with proper electrical insulation and a low common-mode coupling capacitance are considered as the primary design criteria while designing the gate driver. A detailed circuit analysis has been carried out to find the isolation issues in the MV CHB converters, which necessitates a 2ndstage of isolation in the gate driver circuit. Apart from improving the isolation voltage level, the additional isolation stage helps to reduce the coupling capacitance in the common mode path. As the device count for an MV CHB converter is significantly high, the complementary pulses have been generated locally in a CPLD-based delay card, which reduces the count of the optical cables and the associated components. It helps to make the system simple and cost effective. Finally, the design of the proposed gate drivers and associated delay cards are verified in a hardware prototype of 1.65kV/300V, 10kVA Solid State Transformer (SST).

In order to explore peptides for future electronics applications, we have elucidated two different dipeptides consisting of positively charged and negatively charged amino acids namely Histidine-Aspartic and Histidine-Glutamic using NEGF-DFT approach. These two different molecules are bridged within three distinct but symmetrical electrodes of Au, Ag and Cu thereby forming six molecular devices. The Au-His-Glu-Au and Au-His-Asp-Au molecular devices offer the highest rectification ratio of 13.53 and 8.38, respectively. Similarly, Ag-His-Glu-Ag and Au-His-Asp-Au molecular devices offer the most significant negative differential resistance regime with peak to valley current ratio of 1.66 and 1.34, respectively.

PCB Rogowski Coils (PCBRCs) are becoming increasingly popular as a switch current sensor for SiC Power modules in applications such as overcurrent protection, peak current mode control, and junction temperature estimation. In order to increase the PCBRC's noise immunity in the presence of electromagnetic interference, a compensation structure is necessary. This paper compares a screen-return and a trace-return PCBRC compensation structure. Trade-offs in sensitivity and bandwidth are discussed when fabricating both designs on a four-layer PCB stack-up. The noise immunity of both the compensation structures is evaluated with the aid of theoretical models and experimental data.
