Authors: Arulmurugan P.
Published: February 2023

The conventional concrete is enhanced by the addition of fibers in it. The brittleness in concrete is reduced and the adequate ductility of concrete is ensured by the addition of fibers in concrete. The fibers used are polyvinyl alcohol powders and steel fibers in various volume combinations. The main reason for adding fiber to concrete matrix is to find its compressive strength, split tensile strength, flexural strength and deflection test. The base polyvinyl alcohol is highly resistant to the majority of aggressive agent and will never oxidize when exposed to the condition which causes the steel to rust. The hybrid fibers of various combinations in polyvinyl alcohol powder is 0.1%, 0.25%, 0.5% and steel fibre 0.5%, 0.75%, 1.0% are decided to use in concrete mix. The workability of these fiber reinforced concrete mix will be increased by addition of super plasticizer.

Bio sorbents are commonly used inremoving toxic heavy metal ions from wastewater. Bel leaves are used in temples and immersed in water after offering prayers since ancient times. In the present study, a packed bed continuous column was used to remove lead ions from contaminated water with modified bel leaf powder. The bel leaf powder was polymerised during in-situ polymerisation of aniline in the presence of strong oxidant at low temperature. This modified polyaniline coated bel leaf powder had more capacity to adsorb lead ions. It adsorbed 97.6% lead ion as compared to 90% adsorbed by raw bel leaf powder. Packed column dynamics were also studied for different flow rates (5-25 mL/min) of the adsorbate at different depths along the column. Clogging of the pores and channelization was observed along the column with passage of time, which led to change in lead ion concentration, % removal, adsorption capacity and time of exhaustion along the length of the column. Maximum lead ion removal obtained was 19.1mg, 18.7 mg, 18.36 mg and 18.05 mg at the ends of sections S1, S2, S3 and S4. The exhaustion time was 46 mins, 51 mins, 61 mins and 70 mins respectively for sections S1, S2, S3 and S4. Desorption study showed 96.3% desorption of lead with 0.1 M HCl as eluent.

Authors: Pal Manisha , Chauhan A. K.
Published: February 2023

Solar energy is the most prospective source of energy in recent years. Investigation is going on to utilize the solar energy by various academicians and researchers. The main problem in harnessing and using solar energy is its discontinuous nature. Solar energy is not available continuously for 24 hours. So, there is a need to develop a method to store thermal energy during sunshine and utilise this stored energy as per requirement. Some materials available called phase changing materials (PCMs) which can store large amount of thermal energy in the form of latent heat. This energy can be used to heat the water for domestic purposes during evening hours. In this work, an experiment was carried out on parabolic solar concentrator to check the feasibility of using phase changing material as a solar energy storage medium to heat the water. Two containers were put on the concentrator to heat the same amount of water. One container was with PCM material and the other container was without PCM material. The energy efficiency of the system with pcm storage was greater than the system without pcm storage. It means that the pcm storage system is able to trap more of the incident radiation in the form of thermal energy. The exergy efficiency of the system with pcm storage was also higher than the system without pcm storage.

Java based suggestion model for organizing social events under Corporate Social Responsibility
Authors: Moorjani Gunjali , Jindal Mayank , Guglani Lakshay
Published: February 2023

Currently most of the organizations have their own CSR activities and perform social their events separately. Due to lack of resources and limited budget, their ability to perform these activities on larger scale or in remote areas remains restricted.Also, other corporates may not be aware of such events, so that they can actively participate as well. So the idea is to develop an organized Common Corporate Social Responsibility Portal where different corporate or individuals can come together and collectively provide valuable service to society.Therefore, this model is designed to provide suggestions to the corporate to conduct the events by collaboration and working hand in hand with each other. Once the companies post their event on the portal, our internal algorithm will work on some parameters on the basis of which it will send suggestions to the companies via e-mail to conduct the events together in order to make it much more successful and enable the event to make a positive impact on the society. The parameters of suggestion used here are on the basis of-Location of the event, Date of event, Category of event, Most frequent type of event ( Evaluated for displaying suggestions by the individuals to conduct any particular category of event in their locality). If all of these match for any of the corporate, an automated suggestion e-mail would be sent to both the corporate for collaborating together (The final decision of accepting or rejecting the suggestion depends on the choice of corporates itself). Along with this the companies will be displayed suggestions to conduct any particular category of event in their locality under the suggestions section on the portal based on their previous interests or most frequent category of event. This will aware the corporates and increase their reach in remoter areas as well.

Published: February 2023

Tracking multiple persons is a challenging task when persons move in groups and occlude each other. Existing group based methods have extensively investigated how to make group division more accurate in a tracking-by-detection framework. However, few of them quantify the group dynamics or consider the group in a dynamic view. Inspired by the sociological properties of pedestrians, this work proposes a network that tracks the moving persons.This work uses CNN algorithm by extracting the ROI based HOG features to track more accurately without any interference and to obtain a robust free result. It can be done by considering the thresholding values of the person and based on the thresholding bboxes are assigned to the persons to keep the track s of the persons being detected. Implementation of algorithm, creation of user Interface, leads to observe the performance criteria of the persons being tracked which will gives us accurate and robust free results and widely used in video surveillance and generates direct response. As in the case of any accidental decisions taken by a manual observation can be replaced by using this kind of network. CNN based tracking can overcome the problem of manual observation very accurately based on region of Interest.

Published: February 2023

In attempt to examine the relationship between monetary policy and stock market efficiency, two proximate monetary policy regimes were chosen for the study - Sanusi’s administration (2009-2014) and Emefiele’s administration (2015-2019). Employing the multiple regression (OLS) technique reveals that money supply, interest rate, and monetary policy rate, all exert positive and marginal influence on market capitalization under Emefiele’s administration (2015 - 2019), however, under Sanusi’s administration (2009-2014), MS and INT exert significant influence on MCAP, with INT and MPR showing negative relationships, all complying with the a priori expectations. Also, considering the coefficients of determination, 99.9% and 83.0% respectively under Sanusi’s and Emefiele’s regimes, the study therefore conclude that monetary policy instruments under Sanusi’s administration were efficiently managed enough to propel the efficiency of the stock market than that of Emefiele’s administration. The study shows that the government through the monetary authorities should be cautious enough to avoid discretionary policies that might hike the rate of interest; as monetary policy rate through the interest rate channel has a negative relationship with stock market prices. Also, the place of consulting predecessors in policy-making is important especially where macroeconomic growth is conceived as the overall goal to be delivered.

PHEV chargers are known for two types as off board and on-board chargers. In this, 1-phase integrated on-board charger utilizing Fuzzy Logic based PEV 3-phase ac machine (PMSM) with its converter for traction, is proposed. The process for charging enables Power Factor Correction (PFC) in the source end. The 3-phase windings of the machine are used in the place of inductors to act as interleaved boost converter. A circuit utilizing 3-phase PMSM is built in MATLAB SIMULINK as well as verified the execution by using Fuzzy Logic Controller (FLC). An approximately unified power factor (PF) with less amount of THD of input current is obtained.

Agriculture has been the dominant sector of India’s Gross Domestic Product. Contribution by agriculture and other allied sectors is pegged at more than Rs 18 lakh crore in FY19. Crop Residue Management is a challenge for the farmers all across the nation. From the total residue produced in the country, nearly 99.2 MT is burnt at the farm, of which more than 60% is by rice and wheat. Lack of traditional use of residue, clearing the field in short time to sow the next crop in time leads to stubble burning. Stubble burning has become a major pollutant lately. Burning crop residue is a crime under the Air Pollution Control Act of 1981. Although, government’s execution lacks firmness, thus encouraging finding the alternatives. One such process is Torrefaction. This agricultural waste can be efficiently utilized for the purposes which currently are being served by coal based power plants, with additional advantage of residue management. In this work, effect of torrefaction on rice stubble, and the physiochemical properties are discussed. Results so obtained are conducive in designing feasible logistic studies, and more applications of farm based agricultural residue. The torrefaction behaviors of the agricultural residues from plains of North India of rice straw were investigated, and the torrefaction process carried on them resulted in a proof that the torrefied biomass of plant origin has energy potential and calorific value equivalent to that of conventional fossil fuels. This paves way for deploying the process of torrefaction in sustainable energy generation.

DMAIC methodology of Six Sigma is a quality improvement and problem solving technique for an organisation. Majorly manufacturing and production industries implement this technique for betterment of the process. The study in this paper is based on implementing DMAIC technique of Six Sigma in vocational education and training for improving the quality of vocational education while considering the student’s perspective. Variety of quality control tools are used in this study to identify the factors affecting the quality education and to solve the issues for the same. During study some key factors like unsatisfactory internship during industrial semester, less time devoted to the practical and lack of interpersonal skills among students are identified. The solutions for the same are found out in a systematic way by using quality control tools (Pareto chart, check sheets, Fish bone diagram). After implementing these solutions for respective issues the Sigma level increased so the overall percentage of satisfied students also increased by 20% for three vital variables. Though still there is a scope of improvement in the mentioned issues but this study will help academician to understand the quality concept in vocational educational and training.

Published: February 2023

Solar liquid collectors are good candidate of heat transfer enhancement. The efficiency of a solar liquid collector can be improved by augmenting tube side heat transfer using enhanced techniques used in heat exchangers. Various types of heat transfer enhancement techniques has been used in heat exchangers which are mainly classified in two types, active and passive techniques. Solar liquid collectors can also be enhanced by these active and passive devices. Passive techniques, mainly swirl flow devices are more popular enhancement techniques in solar liquid collectors as they do not require any external source of power and also they do not affect the mechanical strength of tube material. Initially twisted tape inserts and conical inserts were popular passive devices used in enhanced solar liquid collectors mainly because of availability of established correlations. Wire coil inserts are relatively less experimented passive technique. This study is focused on tube side heat transfer augmentation of a solar flat plate liquid collector by wire coil inserts and effect of various dimensionless parameters on thermal efficiency of solar collector.

In this paper, a new version of the new Hybrid Boost DC-DC ready to draw power from two different DC sources for standard DC-bus feeds is presented. An important feature of the proposed converter is that both sources provide simultaneous power to a lower load than the reduced current rate. This feature is very attractive for DC grid applications. With the analysis of the time zone, steadystate performance is established and the transformational power correction parameters are obtained. In this paper, a powerful converter is introduced, with its operating principles based on charging pumps and converters of reinforcement series. In addition, although three switches are used, no separate gate driver is required instead of one bridge gate driver and one gate driver on the lower side. As such, the proposed converter is easy to analyze and easy to operate. In addition, additional test results are provided to confirm the effectiveness of the proposed converter.

Different researches are conducted in studying the manufacturing process in different industries like Food Processing, Rolling mill, Grinding process, Distillation unit etc. The applications of 6 sigma has been successful in achieving increased output and better finished products apart from increasing profit margin but none of these researches were conducted in Indian textile industry and application of 6 sigma in improving overall productivity is yet to be implemented. This research is intended to study manufacturing process of Indian textile company Dewan textile located in Meerut and apply 6 sigma tool to improve processes in various departments and also achieve good finished products apart from improving profit margin of company.For any company to have financial gains it is imperative to reduce defect rate and improve yield of product manufactured. Higher defect rates reduce Profit margins therefore companies strive to decrease defect rate of the product during manufacturing to maximum possible extent. This is accomplished by various inspection methods during production cycle and implementing changes as and where necessary. Yarn is manufactured in textile industry by going through number of processes carried out at various departments which raises defect rate to a huge extent. This project studies manufacturing processes involved in various departments of yarn manufacturing process and DMAIC tool of 6 sigma is implemented in winding department to reduce defect rates before finished product goes to customer. Final package is made in winding department from where end product is directly sent to customers and arises possibility of customer complaint.
