Authors- M.Tech. Scholar Deepak Mittan
Abstract- With the progressing of age, both texture and shape of the face affected which is causing face recognition is most difficult task. Solution for this is to apply a model to shows the face with its identity and aging variable is probabilistic model. With condition of as the age is processed, few peoples are looking younger or may be older when compare to other person who is of the same age. Therefore, current datasets of face with the real age mark for age invariance face recognition (AIFR) will introduce new learning methods or algorithms. Experimental results suggest that our Quadratic Support Vector Machine- Principal Component Analysis (QSVM-PCA) achieved better results especially when the age range is large than other existing techniques of face-aging datasets of FGNET. The maximum accuracy achieved by demonstrated methodology is 98.87%.

Authors- M.Tech. Scholar Chandan Kumar, Assistant Professor Gyanender Kumar
Abstract- Signature acts as a strong authentication feature of the signer to validate the identity of an individual and used to preserve their valuable assets such as banking, insurance, healthcare, ID security, document management. A person’s signature is never entirely the same. Orientation of signature may varies. The signature can vary substantially over an individual’s lifetime. An Off-line Signature Verification System (OSVS) with a novel feature extraction procedure has been described. Fusion of concentric squares having geometric features, zone-based slope as well as slope angle have been considered as input patterns. The strong feature set thus obtained makes the OSVS accurate. Verification was performed by using Support Vector Machine (SVM) technique with different kernels the developed SVM is successfully tested against 336 signature samples and the classification error rate is less than 9.7% and this is found to be convincing. The accuracy of proposed algorithm is achieved up to 90.30 %.

Authors- Achille PAGUI Déblème, FOUDJET Amos Erick, FOADIENG Emmanuel, Njoh Ekoume T. R. S., TALLA Pierre Kisito
Abstract- The objective of this work is the application of the methodology for analyzing the behavior in bending of the structure of sandwich beams base on the second order of asymptotic method in a three-point structure. The development of this work is based on the application of two models, the model of Foudjet-Metangmo and the model of Guitard. This work includes the knowledge of all the physical elastic constant of the sandwich beams. The curves have been obtained by the software named python. The curve obtained presented to us a very small variation. This result confirms the fact that the second order of asymptotic method doesn’t bring a significative change in the behavior of the solution. This result was predictable because the asymptotic methods deal with small variation due to the presence of the epsilon parameter which is very small.

Authors- Hakki Soy, Sabri Koçer
Abstract- Machine-to-Machine (M2M) communication and Industrial Internet of Things (I-IoT) are key technologies to realizing the vision of smart factory. But, most of the field devices use vendor’s proprietary protocols, and hence interoperability is often not possible entirely. The OPC UA (Object Linking and Embedding for Process Control) standard provides interoperability in industrial automation systems by creating open specifications that allows the real-time communication between field devices of different vendors. This study reviews the relevant and contemporary literature on the industrial communication networks that are shaping current automation applications, as well as the future trends in wireless networking technologies.
A Revire on CUK-ZETA Multi-Input DC-DC Converter
Authors- M.Tech. Scholar Harshil shrivastava, Professor Dr. K.T Chaturvedi
Abstract- This project presents a new transformerless buck-boost converter based on the ZETA converter. The proposed converter has the advantages of ZETA converter, such as buck-boost capability, DC isolation from input to output and DC output current. The voltage gain of the proposed converter is greater than that of the conventional ZETA converter. In the proposed converter, only one main switch is used. The proposed converter can provide a lower AC voltage. Therefore, the low resistance of the main contact can be selected to reduce displacement loss. The proposed converter topology is simple; therefore, controlling the conversion is straightforward. The converter has a continuous output current. The mathematical analysis of the proposed converter is recalled. This project proposes a double input DC-DC converter based on the integration of CUK and Zeta converters, which performs a boost operation suitable for telecommunication supplies. In the proposed converter, the input DC voltage can be interrupted or increased, and the input DC power supply can also supply the load separately or at the same time. This combination causes the output voltage to be negative, but by introducing diodes and capacitors across the bridge the polarity is reversed to a positive voltage at the output. The converter can provide up and down conversion with reasonable duty cycle. The state of stability of the converter is analyzed and introduced in this recommendation.
A Review on Stability Analysis of DC Microgrid with Hybrid Energy Storage System
Authors- M.Tech. Scholar Shubham Sahu, Dr. K.T Chaturvedi
Abstract- The AC and DC power system structures need to be modernized to meet consumer demands. DC microgrids are suitably admired due to their high efficiency, consistency, reliability, and load sharing performance, when interconnected to DC renewable and storage sources. The main control objective for any DC microgrid is providing proper load–power balancing based on the Distributed Generator (DG) sources. Due to the intermittent nature of renewable energy sources, batteries play an important role in load–power balancing in a DC microgrid. The existing energy management strategy may be able to meet the load demand. However, that technique is not suitable for rural communities’ power system structure. This research offers an energy management strategy (EMS) for a DC microgrid to supply power to rural communities with solar, wind, super capacitor and batteries as input sources The conventional design method considers the rated super capacitor voltage in the modelling and design of controllers. The conventional method of controller design can potentially make the system unstable or introduce ringing in the DC link voltage at low super capacitor voltage. In this the sensitivity of DC micro grid stability with respect to super capacitor voltage variation is analyzed and a control design method is proposed to ensure the stability of DC micro grid in all operating modes. The design and stability analysis of a DC micro grid with battery-super capacitor energy storage system under variable super capacitor operating voltage.

Authors- M.Tech. Scholar Prince Patel Professor Krishna Pal Singh Rajput
Abstract- Nowadays, there are numerous attempts in the utilization of renewable energies such as geothermal heat, wind energy, and solar energy as clean energy sources for electricity production or cooling processes. Also, waste heat can be considered as renewable and clean energy, since it is free energy and there is no direct carbon emission. Waste heat can be rejected at a wide range of temperatures depending on the industrial processes. In this study, the energy and exergy analysis of a combined cycle was carried out. This cycle consists of an organic Rankine cycle and a vapor compression refrigeration cycle for producing the cooling effect. Four organic fluids were used as working fluids such as R600a, R245fa, RC318 and R236fa. The parametric analysis allowed us to characterize the combined system and to study the effect of some parameters that will be used to estimate the thermal and exergy efficiency of the studied system. Due to environmental issues of R600a is recommended as a superior candidate for.
A Review on Thermodynamic Analysis of Triple Effect LiBr-H2O Vapour Absorption Refrigeration System
Authors- M.Tech. Scholar Gagan Pashine, Assistant Professor Roopanshi Tomar
Abstract- The absorption refrigeration system (ARS) is becoming more important because it can produce higher cooling capacity than vapor compression systems, and it can be powered by other sources of energy (like waste heat from gas and steam turbines, sun, geothermal, biomass) other than electricity. In the recent years, the interest in absorption refrigeration system is growing because these systems have environmentally friendly refrigerant and absorbent pairs. From the literature review it seems less work has been done on performance analysis of the reverse flow cycle. Also, optimization of the solution distribution ratio in the parallel flow cycle has not been well defined. None of paper show effect of using precooler on the COP in the vapour absorption system. Therefore Energy analysis of triple effect flow cycles has been done using precooler in the absorption system.

A Review on Different Methods to Prevent Black Hole Attack in MANET
Authors- M. Tech. Student Nitiksha Sharma, Assistant Professor Mr. Sujeet Mishra
Abstract- Mobile ad hoc networks (MANET) are dynamic, decentralized and infrastructure less network, where at any given point of time nodes can join or leave the network. Due to the property of flexibility and simplicity MANET are widely used in military communication, mobile conferencing and emergency communication. As Ad-hoc networks are autonomous mobile nodes, they form a temporary based network which has no fixed infrastructure. Every node in the network is autonomous hence they act as host as well as router. Due to this nature of MANET, where any node can join or leave the network without any permission, security is the main challenge in such networks. One of the major security issues in MANET is Black hole attack. It occurs when a malicious node referred as black hole joins the network. during the process of discovering route this node acts as if it has the route to the destination and takes all the packets into it and does not forward to the desired destination, instead it drops all the packets. In this paper, we have survey on few of the techniques and methodologies for detecting and preventing black hole attack in MANET using AODV routing protocol.

A Review of Friend Recommendation System Using Machine Learning Method
Authors- M.Tech. Student Shweta Soni, Assistant Professor Pratiksha Singhai
Abstract- Friend recommendation is one of the most popular characteristics of social network platforms, which recommends similar or familiar people to users. The concept of friend recommendation originates from social networks such as Twitter and Facebook, which uses friends-of-friends method to recommend people. We can say users do not make friends from random people but end up making friends with their friends’ friends. The existing methods have narrow scope of recommendation and are less efficient. We propose a new friend recommendation model to overcome the shortcomings of existing system. For better friend recommendation system with high accuracy, we will use collaborative filtering method to compare similar, dissimilar data of users and will make a recommendation system which gives user to user recommendation based on their similar choices, activities and preferences. Location based friend recommendation system are becoming popular because it brings physical world to digital platform and gives better insight of user’s preferences or interest This recommendation system will increase the scope of recommendation from one user to other with similar set of interest and their location.

Ultra-low Power Small Size RF Transceiver Module for 5G/LTE Applications
Authors- M.Tech. Scholar Shiju Koshy, Dr. Uday Singh Panwar
Abstract- The signal processing is advancing day by day as its needs and in wireline/wireless communication technology from 2G to 4G cellular communication technology with CMOS scaling process. In this context the high-performance ADCs, analog to digital converters have snatched the attention in the field of digital signal processing. The primary emphasis is on low power approaches to circuits, algorithms and architectures that apply to wireless systems. Different techniques are used for reducing power consumption by using low power supply, Successive Approximation Register (SAR) ADCs are one of the most popular ADC architectures used nowadays. SAR ADCs are well suited to CMOS integration, as they use mostly digital components. They offer a good compromise between sampling rate, power, and dynamic range and area. Their performance is however limited by mismatch in their internal components, and their conversion speed is not very high among the different ADC architectures due to their iterative nature. A Proposed a technique to enhance the speed of low resolution SAR ADC. In capacitive DAC based SAR ADCs, the capacitance will be increases with resolution. As the settling time will be increases, the conversions speed decreases. The scheme is applied in a 14-bit SAR ADC to determine MSBs much faster before main DAC settles. The scheme is also applicable for improved resolution of 14-bits with unit capacitance 500fF. Thus speed of a SAR ADC can be improved without reducing the total capacitance in the circuit. Scheme is designed will be developed on LT Spice. To this end, we are proposing an improved time-efficient transceiver module which includes the 14-bit SAR ADC, The operating voltage of SAR-ADC is 1.2 V0.65nm CMOS technology will be used for the implementation of the proposed solution.
Optimal Visual Cryptography Scheme for Color Image
Authors- Assistant Professor Ancil John M., Assistant Professor Sujithra B.S.
Abstract- Visual cryptography is a powerful technique that combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares that can be stacked together to approximately recover the original image. Unfortunately, it has not been used much primarily because the decryption process entails a severe degradation in image quality in terms of loss of resolution and contrast. In this project introduces the concept of optimal visual information pixel (VIP) synchronization using genetic algorithm and error diffusion to attain a color visual cryptography encryption method that produces meaningful color shares with high visual quality. VIP synchronization retains the positions of pixels carrying visual information of original images throughout the color channels and error diffusion generates shares pleasant to human eyes. For more efficient secret image extraction we use genetic algorithm along with contourlet image denoising method, feature preservation and noise suppression.
A Study of Structure and Properties of Black Hole
Authors- Neeraj Kumar Mishra, Priyanka Vaidya
Abstract- The structure of a black hole consists of Event horizon, Singularity, Photon sphere, Ergo sphere and ISCO. Event horizon is a boundary in spacetime through which matter and light can pass only inward towards the mass of the black hole. Gravitational singularity is a region where the spacetime curvature becomes infinite. The photon sphere is a spherical boundary of zero thickness in which photons that move on tangents to that sphere would be trapped in a circular orbit about the black hole. Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere. In general relativity there exist an innermost stable circular orbit (often called the ISCO) inside of which any infinitesimal perturbations to a circular orbit will lead to inspiral into the black hole. As far as properties of the black hole are concerned, a black hole has only three independent physical properties: mass, charge, and angular momentum, the black hole is otherwise featureless.

A Study of Formation and Evolution of Black Hole
Authors- Neeraj Kumar Mishra, Priyanka Vaidya
Abstract- Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away.

Numerical Analysis of an Un-Orthodox Stiffened Double Hull Oil Tanker Upon Impact by a Rigid Bulbous Bow
Authors- Abdillahi Bakari, Professor Emeritus Moustafa El-Gammal
Abstract- This paper presents the design of hull structures with unorthodox light stiffeners as compared to the standard available steel sections with the aim of increasing the overall hull strength. The Y stiffeners as referred to as herein be designed, analyzed and compared to the standard Flat, L, Angle sections, Unequal angle sections and Offset bulb sections. The energy absorption capacity of the hulls strengthened by these light stiffening members and the extent of the damage on the hull plates with possible penetration and piercing of the bulbous bows are investigated. The amount of deformation on side shell plates, stringers, web frames are each studied as an indicator of the amount of distortion that can be induced as a result of the impact from the side collision. Six models of a double hull oil tanker mid-ship sections are modelled in Abaqus 6.144. They are then collided with rigid bulbous bows whose probabilistic dimensions are obtained from statistical formulas. Their results are compared to that of the Y stiffened hull. Outer hull plate rupture latest in the Y stiffened hull than all the other hulls, at a distortion of 0.2m, a total resistance force of 1518900N with a total energy dissipation of 152587J. The nearest in resistance of the other standard stiffened hulls, to the Y stiffened one are; the L and Unequal angle sections with 56% and 55% force, 45% and 44% energy of the Unequal and T3 sections to the Y hull. These results show that the Y stiffened hull possess the highest resistance to damage upon impact and the most energy absorption capacity than all the other standard stiffened hulls. The results of the FEA in Abaqus 6.144 are compared with an analytical method adopted from other researches with good agreement between the results.

A People Counting Method Based on Machine Learning
Authors- M. Tech. Student Vinay Kaithwas, Assistant Professor Lokesh Parashar
Abstract- In this Paper proposes for a people counting method based on head detection and tracking, according to the People counting method based on head detection and tracking to evaluate the number of people who move under an over-head camera. There are four main parts in the proposed method: foreground extraction, head detection, head tracking, and crossing-line judgment. The proposed method first utilizes an effective foreground extraction method to obtain foreground regions of moving people, and some morphological operations are employed to optimize the foreground regions. Then it exploits an LBP feature based Adaboost classifier for head detection in the optimized foreground regions. After head detection is performed, the candidate head object is tracked by a local head tracking method based on Mean shift algorithm. Based on head tracking, the method finally uses crossing-line judgment to determine whether the candidate head object will be counted or not. Experiments show that our method can obtain promising people counting accuracy about 96% and acceptable computation speed under different circumstances.

Authors- M. Tech.Student Deepak Chouhan, Assistant Professor Lokesh Parashar
Abstract- The expected advent of the Internet of Things (IoT) has triggered a large demand of embedded devices, which envaisions the autonomous interaction of sensors and actuators while offering all sort of smart services. However, these IoT devices are limited in computation, storage, and network capacity, which makes them easy to hack and compromise. To achieve secure development of IoT, it is necessary to engineer scalable security solutions optimized for the IoT ecosystem. To this end, Software Defined Networking (SDN) is a promising paradigm that serves as a pillar in the fifth generation of mobile systems (5G) that could help to detect and mitigate Denial of Service (DoS) and Distributed DoS (DDoS) threats. In this work, we propose to experimentally evaluate an entropy-based solution to detect and mitigate DoS and DDoS attacks in IoT scenarios using a stateful SDN data plane.

Fast Unsupervised Bayesian Image Segmentation with Adaptive Spatial Regularization
Authors- Ajit Kumar, Hod Vimal Kumar
Abstract- Image segmentation is a process of dividing the image in to some distinct regions. These region shave specially coherent in nature and have similar attributes. This technique is widely used for image analyses and to interpret the desired feature. In this present paper we will study about the hidden Markov random fields and find its expectation maximization algorithm. The main idea behind developing HMRF is to adjoin the “data faithfulness” and “model smoothness”, that show very similar nature with the active contours, GVF, graph cuts, and random walks. Here we also uses the HMRF-EM along with the Gaussian mixture models, and then we use it on color image segmentation process. These algorithms are implemented in MATLAB. In color image segmentation experiments, we observe that the result obtain from HMRF segmentation are much smoother then the direct k-means clustering. The segmented object is much closer to the original shape than clustering. The segmentation time for Bacteria 1, Bacteria 2, SAR & brain images are 0.35, 0.43, 0.12 and 0.12 respectively. The accuracy for Bacteria, Bacteria 2, SAR & brain images are 97.70 %, 98.06%, 98.89% and 97.35 % respectively.

, Asst.Prof. Bharti Chourasia
Abstract- – The aim of data compression is to reduce the memory space or the transmission time, especially for wireless sensor networks (WSNs) because of the energy constraints. In the past, data compression and cryptography were kept separated because any data can be compressed if necessary and then encrypted. Anyway because of the rapid progress in computing technology, the encrypted data could be secure no longer in a few years. A way to increase security is joining compression and encryption, using one of the existing cryptography techniques. This scheme has been adopted especially for images. In this paper different approaches for image compression are discussed.

Authors- Associate Prof. Ashish Kumar Jain, Asst. Prof.C.P. Patidar, PG Student Alka Patidar, PG Student Ritubala Patidar
Abstract- – Agriculture is the primary type of revenue for a dominant part of people in India and the fundamental need of human existence. Agriculture plays an important role in many country’s growths. Because of different weather and local circumstances, the yields get contaminated by various types of disorders. The majority of disease can be noticed on plant leaf at the initial phase and gradually impact the entire plant can result in less crop cultivation. Identification of illness in plants is a significant factor to limit the loss in the agricultural sector and increasing the quality of agricultural products. As there are countless plants on the fields, it is quite challenging during natural eye observation to identify the illness and to identify individual plant breakdowns in agricultural areas. It is necessary to assess all crops to avoid the expansion of infection in a wide area. To guarantee great quality with high product output, it is important to have precise disease determination and control activities to prevent disease in the early stage. This suggested model will be an AI-based program for the crop leaf infection identification to make it fast and simple diagnosis and later analyzing this and producing predictable resolutions toward the prevention of huge crop cultivation loss. This system is aimed at improving the profitability of yields in farming. In this model, we need to follow some steps namely, image data set collection, pre-preparation, feature selection from leaf image, evaluation, and classification of diseases.
