Abstract
We report a simple and low-cost technique to prepare a composite comprising of activated carbon and few layers of graphene sheets and fabricated as electrode material for supercapacitor (SC) applications. The composite is characterised by using Raman spectroscopy, powder X-ray diffraction (XRD), scanning electron microscope (SEM) and current-voltage (I-V) measurements. The synthesized composite is investigated by using galvanostatic chargedischarge (GCD) and cyclic voltammetry (CV) measurements in 3M KOH aqueous electrolyte to evaluate its electrochemical performance. The composite results high specific capacitance from 173 to 564 F/g at different scan rates (100-5 mV/s), analysed by CV and the capacitances resulted in GCD measurement were 196 to 587 F/g at various current densities (5-1 A/g). The cycle stability of the as-prepared AC/graphene composite is also tested and observed that 89% of capacitance is retained even after 5000 cycles which reveals the excellent long term chargedischarge stability of the prepared composite. Therefore, the composite performs very well in storage as well as life cycling. The obtained results suggest that AC/graphene composite can be a suitable electrode material for high-performance SC.

Abstract
The need for power is constantly rising, with the current economic growth. In the power distribution system, transmission lines are the most important part as they play an indispensable role in transferring power from the power plant to the load centres. Transmission lines are done to faults which are largely caused by dampness in the paper insulation, weakness of the cable, or defects in splices or other accessories. The presence of these faults cases the power transmission efficiency to become low, giving rise to a huge annual power loss, Finding and designing new methods to identify the type of defect and its location, is the key to increasing the reliability and optimal performance of the system. This paper reviews about various approaches used for determining the location of underground cable faults and determining the faults using thermal imaging.

Published: July 2021

AbstractThis article provides a review on effect of processing parameters on the quality and performance of thin films of rare earth materials deposited through PVD RF sputtering technique. The applications of these thin films include optical, electronics, medical films, defence and renewable energy technologies. A systematic review of the literature revealed that the sputtering parameters such as plasma power and substrate temperature have the most impact on the grain size of the deposited thin films. Larger grain size was observed to be at higher sputtering power and higher substrate temperatures, while lower grain size was obtained when the sputtering power is decreased. The optical property, in particular the band energy gap (Eg) was found to improve with the film thickness. Thin films produced at higher doping concentration and subsequently annealed at higher temperature was found to increase the crystallinity of thin films.
Modeling anisotropic fracture in a metal-fiber reinforced composite system
Authors: Pranavi Dhaladhuli , Rajagopal Amirtham 
Published: July 2021

Abstract
Hybrid structures consisting of metal and composites can be applied to specific requirements of different applications. The computational modeling of composites is quite complex compared to homogeneous and isotropic materials like metals because of the heterogeneity introduced due to the presence of different phases such as matrix, fiber and matrix-fiber interface, and anisotropy due to the fiber alignment. The crack propagation in a composite material depends on a combination of various damage modes, namely, fiber pull-out, matrix cracking, delamination. The strength and stiffness of the composite depend on the mechanical and fracture properties of the individual phases, and the fiber inclination. The metal-composite interface is modeled using the cohesive zone approach. A nonlocal diffused approach is proposed to model the anisotropic failure in composites reinforced with unidirectional and woven fibers and the interaction of the crack with the interface. Parametric studies are conducted to understand the role of fiber orientation and interface fracture properties of the system. The proposed model is illustrated through numerical examples to understand various failure mechanisms in a metal-composite system.

Abstract
In recommender systems, our main task is to predict the rating of a new product from the authorized user and then return the best rating for the particular item and this technique reduced the existing prediction error rate. Our proposed system is user-item rating matrix prediction based on Synergetic filtering techniques and this technique is more efficiency compared to other technique. Proposed System are providing personalized recommendation for help the users accord with information overburden problem. However, the techniques are the data insufficiency of the user-item rating matrix underlying for brand-new items and users are severely affected by Synergetic filtering technique. Since the character of common links and items between more accessible by the users in the Internet and this paper exploits the common links of users and the character of items to overcome the existing problems and to ease the rating insufficient effect. However they may need excessive computational moment, and they often accost the insufficient problem which negatively modify the ability of the system. Specifically, we initially propose a Kernel-based Attribute-aware Self adaptation and multi thresholding model to blend the character information of items into matrix factorization and then introduce self-adaptation and multi thresholding. KASM can find the indefinite interactions among characters, users, and items, which reduce the rating insufficient effect for brand-new items by nature. In this paper we suggest a quick recommendation algorithm based on self-adaptation and multi thresholding. Self-adaptation in its genuine meaning is a state-of-the-art method to alter the setting of control specification. It is called self-adaptive because the algorithm controls the setting of these specification itself sink them into a distinctive genome and emerging them. It is construct to deal with the specified drawbacks and enhance the prediction quality. Extended analysis on two real world data sets establish that our proposed method can attain necessarily improve performance than other state-of the-art-methods. In this method we get the accuracy rate of predicting user rating will be 95%

Components of a formula car experience many forces and have to sustain in various conditions. The design of the components must be keeping in mind the safety and efficiency of the component. In Formula racing, the car has to be as light as possible. Cars with powerful engines are faster in the straights, but cars with lighter weight are faster in the corners. Optimizing the components to be light in weight is a critical task and has to be done meticulously. Several conditions and forces have been considered, and the simulation has to be as close to the real-life conditions as possible for accurate results. This paper records the detailed study, design, and analysis done for the weight reduction of the component. Data from previous years’ performance of the car was also considered during the analysis. Based on the data, the material selection and designing of the component was made in Solidworks. The Structural and Fatigue analysis were done in ANSYS Workbench; based on these results, the component’s optimization was done.

Published: July 2021

Abstract
This research details the deposition and characterization of adding zinc (Zn) impurities with different doping concentrations (1%, 3%, and 5%) into copper oxide (CuO:Zn) by using a jet nebulizer spray pyrolysis system. The impact of zinc doping on the different copper oxide properties was investigated. The structural studies confirm that pure copper oxide and zinc doped copper oxide thin films are matched with monoclinic structure. High resolution schottky field emission scanning electron microscopy and Energy dispersive spectrum analysis identifies the surface structure and chemical composition of pure CuO and CuO: Zn thin films. EDS spectra reveal the occupancy of Cu, O, and Zn elements in the pure CuO and CuO:Zn thin films. The highest transmittance was observed as 66.91% for 5% Zn concentration. The absorption studies clearly indicated that the absorbance of the films was decreased when Zn doping concentration increase. The energy band gap value (Eg) is calculated as 2.01eV for pure CuO and the value of Eg for CuO:Zn thin films are varied from 2.07 to 2.26 eV. Keithley high resistance and low current electrometer was used to measure direct current conductivity of both pure CuO and CuO: Zn thin films and maximum conductivity value was observed for CuO: Zn (5%) thin film.
Lossless Compression of Satellite Images using a Versatile Hybrid Algorithm
Authors: Swetha V , Premjyoti Patil G , Shantakumar Patil B 
Published: July 2021

Abstract
The remote sensing images taken from various satellites have high resolution and occupy a lot of storage space. It, therefore, becomes difficult to send a greater number of images to the base station. Image compression becomes inevitable in such cases. Satellite image compression decreases repetition in representation of data so that the storage cost and transmission reduces and compensates for the limited on-board resources, in terms of large-scale memory and downlink bandwidth. The aim of this paper is to perform lossless image compression on satellite imagery using a hybrid (DWT-RLE) algorithm to obtain higher compression ratios. This compression is implemented using the software tool MATLAB.

Published: July 2021

Abstract
A data acquisition method to obtain force measurement on an end effector of a serial manipulator is carried out using LabVIEW Data Dashboard to obtain results wirelessly developing an integrated, system between the serial manipulator, a computer and a remote device. A strut array was manufactured with a 4x4 grid and 8 strain gauges were attached on the parallel sides of the 4 rectangular struts based on strain analysis run theoretically using ANSYS to locate position of maximum strain. Two full bridge circuits from the array were then connected to a NI 9219 analog I/O module set up on a NI cDAQ 9174 chassis to measure the force on the struts whenever a load is applied. Tabular results of strain were obtained which varied linearly with uniformly appreciating loads, graphically displayed using LabVIEW GUI. LabVIEW is further connected wirelessly to the NI Data Dashboard app on a mobile via a shared variable engine which generates the results as a shared variable which can then be displayed on other remote devices. Therefore we can say that an integrated wireless system to remote monitor force applied on an end effector of the serial manipulator IRB1410 has been developed successfully.

Published: July 2021

Abstract
Lemongrass (Cymbopogon citratus) essential oil (raw oil) is a natural product with many biological activities and is commonly used in the food and cosmetic industries. In this study, fractions of lemongrass essential oil were segregated from raw oil by vacuum fractionation. These fractions were then examined for their constitution, antioxidant and antimicrobial activities. Gas chromatography-mass spectrometry results indicated a difference in constitution and content of compounds among the fractions and raw oil. β -myrcene was the main ingredient in two fractions, F1and F2, with content 2-4 times higher than the original content in raw oil. At the same time, F4 was the primary fraction for citral recovery, with the highest citral content of 83.53%. Fractions F3, F4, and undistilled oil (Unoil) showed better antioxidation than raw essential oil. On the other hand, the antimicrobial experiments indicated that F1, F2, and F4 had the highest activity in both cases against Staphylococcus aureus and Escherichia coli bacteria. These outcomes could increase the applicability of lemongrass essential oil in many fields, especially in medical and food applications.
Influence of Ni addition on Abrasive wear behaviour of plasma-sprayed Duplex stainless steel coatings
Authors: Edward Anand E , Balasubramanian K 
Published: July 2021

Abstract
Many austenitic and ferritic stainless steels have a higher yield and ultimate tensile strength than duplex steels. The extent to which this is true is determined not only by the alloy’s composition but also by how it is treated. This increased strength is usually accomplished without sacrificing the alloy’s hardness, as long as the alloy does not contain any of the harmful phasing elements. Thus an attempt is made to study the duplex stainless steel being plasma sprayed on a substrate and study its microstructure, hardness, and abrasive wear resistance. The primary objective is to study the abrasive wear resistance of duplex stainless steel coatings on 316 stainless steel. Ni percentage in coatings is varied at the coating stage in weight percentages of 7.0, 7.5, and 8 % and to study its effect on the wear rate of the coatings. The composition of the coatings is confirmed using XRD. A two-body abrasive wear test is carried out to determine the wear rate of the coatings with varying percentages of Ni and varying loads. Besides, the coatings are characterized by optical microscopy. Weight loss measurements of the tested samples are carried out and the data obtained is analyzed through weight loss plots. Also, weight loss data is used to further calculate the wear rate which is analyzed using wear rate plots. Finally, the microhardness of the coatings is determined.
