In a renewable energy system (RES), maintaining the balance of power between supply and demand with minimum cost in homes connected to these systems present one of the most important challenges to consider. Generally, a large capacity of batteries is usually used to store the energy and reused in absence or insufficient power supply in order to maintain the required energy balance. Thus, a hybrid proposed controller is proposed to analyze the stability of Micro Grid system (MG) using Particle Swarm optimisation (PSO) technique. Two modes of controllers are utilised to attain the stability of the MG system. The first PV / WT method works by using the voltage modulated direct power control (VMDPC) to achieve maximum grid power and also used to enhance the maximum power and the steady-state performances. The second mode of battery storage is operating to maintain the voltage and frequency in the MG through the utilization of the conventional controller. The key objective function is to achieve the maximum power and stability of the system with the implementation of the proposed controller. Simulink/MATLAB environment is used to examine the performance of the proposed system.

Nowadays with the increase in advancement of traffic network methodology we have potentials to control traffic congestion and hindrance using huge range of traffic management strategies. Feasibly there are two most promising techniques proffered are chaos theory and reinforcement leaning techniques, the goal of this research technique is to make up a model that self-sufficiently learns by itself the optimal policy. In this paper, we use V-2-V based fuzzy node mechanism and chaos theory that notifies where the traffic could get clustered. On other hand, our reinforcement learning agent makes up discretions (signal status) for the proffered environment.

Deep learning has revolutionised the field of machine learning in near years, particularly for computer vision. Two methods are used to view supervised learning, SNN networks with the handwritten Digit Recognition Problem (NOD) and Normalized Normalized Approximate Descent (NORMAD). Experiments show that the identification accuracy of the prototype SNN does not deteriorate by more than 1% relative to the floating-point baseline, even with synaptic weights of 3-bit. In addition, the proposed SNN, which is trained on the basis of accurate spike timing data, outperforms the equivalent non-spiking artificial neural network (ANN) trained with back propagation, especially at low bit precision, and is in line with the convolutionary neural network that is normally used to train these system. Recent work shows the potential to use Spike-Based Data Encoding and learning for applications of the real world for positive neuromorphism.

By applying machine learning algorithms, patterns are identified or recognized in the process of Pattern Recognition. On the grounds of prior knowledge, the data is collected and sorted. In this method, the raw data is transformed into a susceptible form which can be used by the machine. Electrocardiogram (ECG) Pattern Recognition is the main focus of this paper. ECG keeps a track of heart’s electrical activity. In the field of biometric it is used as a robust biometric. On the person, off the person and in the person, are the three categories for tracking and capturing signals. Only Off-the-person category in which there is no or minimal skin contact, is included in this paper. To analyze and implement data, six baseline methods are utilized. These baseline methods are applied two publicly available databases-CYBHi and UofT. Raw signals and spectrogram of heartbeat are used for studying about representing features. Various machine learning algorithms are also discussed. Implementation for predicting heartbeat as normal or abnormal and heart diseases, is performed.

Nature inspires engineers to build robots with soft and flexible materials. Advancements in technology have opened doors for designing compliant and soft robots. Such robots find applications in designing soft surgical tools, soft wearable, implantable devices, etc. which can be used in collaboration with humans to execute a variety of non-conventional tasks. These robots have the ability to achieve any kinematic configurations through deformations. Unlike conventional robots, soft robots interact with an unknown environment with improved dexterity. However, this comes at the cost of increased complexity within existing modeling frameworks which motivated researchers to come up with specialized modeling techniques for soft robots. When a reasonable model is available, the next challenge for soft robots is to design a suitable control law to achieve some desired performance. This article gives some insights into soft robots with a focus on existing control methodologies. It also discusses the state of the art: biological inspirations, modeling, simulation, actuation methods, control and applications in human-robot interaction.

Among the ranking of the largest road network in the world, India stood at third position. According to a survey held in 2016 the total number of vehicles in India were 260 million. Therefore, there is a necessity to develop Expert Automatic Number Plate Recognition (ANPR) systems in India because of the tremendous rise in the number of automobiles flying on the roads. It would help in proper tracking of the vehicles,expert traffic examining, tracing stolen vehicles, supervising parking toll and imposing strict actions against red light breaching. Implementing an ANPR expert system in real life seems to be a challenging task because of the variety of number plate (NP) formats,designs, shapes, color, scales, angles and non-uniform lightning situations during image accession. So, we implemented an ANPR system which acts more robustly in different challenging scenarios then the previous proposed ANPR systems.The goal of this paper,is to design a robust technique forLicense Plate Detection(LPD) in the images using deep neural networks, Pre-process the detected license platesand performLicense Plate Recognition (LPR) usingLSTMTesseract OCR Engine. According to our experimentalresults, we have successfully achieved robust results withLPD accuracy of 99% and LPR accuracy of 95%just like commercial ANPR systemsi.e., Open-ALPRand Plate Recognizer.

In today modern digital world, there is huge need of security in medical field also. Among all modern data transfer techniques, Blockchain is a fast growing technology which provide a cryptodata through which we can transfer data between peer-to –peer node. Blockchain provide security which depends on highly cryptographic schemes. We can integrate blockchain with wireless body area network. Because WBAN is also a very emerging field of medical department. All the data of patient is maintained in a electronic health record (EHR). So Maintaining a EHR is very challenging face of medical field. In WBAN we transfer the patients data among different entities like healthcare server, medical staff, health insurer over the network. So we can provide security in this field through blockchain. In this paper we propose an architectural model of block chain with WBAN. We also mention some challenges which are faced in the field of medical health care applications.
