Objectives: To mine significant subgraphs with user specified objective functions from a set of graphs that are useful for understanding the intrinsic characteristics of data in a scalable approach. Methods/Statistical Analysis: A large number of candidate subgraphs generated during mining process causes both computational and statistical problem. In this paper, Significant SubGraph Mining-SSGM proposes an algorithm to find significant subgraphs by using a small set of representative patterns - coreset that overcomes these problems. Furthermore, an edge graph notation is used to represent a graph that enables to mine patterns directly without using separate mining algorithm. Findings: The number of possible candidates is generally exponential in search space and techniques employed are mostly focussed on monotonic property. The proposed algorithm offers simple, yet efficient optimizations to significantly improve performance by pruning the search space and exploring representative graphs. It avoids enumeration of all frequent subgraphs which cause redundancy and extreme mining time. The identified coreset elements are extended that provide optimal solution patterns and adopted edge graph notation mine subgraphs directly. Application/Improvements: Experimental results shows that the proposed algorithm is effective and efficient for mining significant subgraphs in terms of computational cost, scalability and time over existing methods. The algorithm can be applied to find different types of significant patterns in a scalable manner by using any objective function according to the problem domain including support, correlation measure and feature set.Keywords

The need for systematic follow up of medicines for adverse drug reactions once they are introduced into general use has been widely recognised today. Even in developing countries like India, national pharmacovigilance programme has been started for monitoring adverse drug reactions. In its first year this program mainly aimed to foster the culture of ADR notification among health care professionals. As a part of health care team every pharmacist must have knowledge about adverse drug reaction monitoring systems and pharmacovigilance.Keywords

In this paper, series compensator is proposed to reduce the harmonic distortion in the sensitive load due to the presence of non linear loads in the power system network. The series compensation method is best suited to protect such load against this disturbance. The use of a series compensator (SC) to improve power quality is an isolated power system is investigated. In this paper, a series compensator is proposed and a method of harmonic compensation is described using PI controller and Fuzzy controller. The proposed series compensator consists of Energy Storage System (ESS) and Voltage Source Inverter (VSI), Injection Transformer. The ESS can be a capacitor of suitable capacity. ESS would act as a buffer. Injection Transformer is used to inject the voltage in transmission line in appropriate level. In this way the terminal voltage of the protected sensitive load can be regulated to maintain a constant level. The modeling and simulation of the proposed series compensator was implemented in Matlab Simulink work space. Simulation results showed that the proposed series compensator was efficient in mitigating harmonics and compare with the both controllers and thus improve the power quality of the isolated power system. This approach is different from conventional methods and provides effective solution. If this method is enhanced in future it could provide much more improved power quality.Keywords

In this paper, exponential wave fitting algorithm is proposed for the estimation of harmonics and interharmonics in power system. A appropriate control approach must be provided to ease the harmonics. To obtain suitable control parameter, the harmonics present in the system is to be estimated. In this work, the estimation of interharmonics was done with and without noise. Interharmonics can be thought of as the inter-modulation of the fundamental and harmonic components of the system with any other frequency components and can be perceived in an increasing number of loads. These loads include static frequency converters, cycloconverters, sub-synchronous converter cascades, induction motors, arc furnaces and all loads not pulsating synchronously with the fundamental power system frequency. International Electro technical Commission (IEC) which is the international body recognized as the curator of electric power quality standards (IEC-1000-2-1) officially defined this terminology as ‘Between the harmonics of the power frequency voltage and current, further frequencies can be observed which are not an integer of the fundamental, They can appear as discrete frequencies or as a wide- band spectrum’. A recent IEC-61000-2-2 draft redefines interharmonic as ‘Any frequency which is not an integer multiple of the fundamental frequency’. IEEE Interharmonic Task Force adopted this definition. As harmonics and interharmonics have much adverse effects on the equipment, a proper control strategy must be provided to alleviate the harmonics.Keywords

Outcome Based Education (OBE) came into practice in India in 2014. Earlier the priority of most of the faculty is just to complete the syllabus and for students to score better grade. One of the biggest challenges for faculty members in implementing OBE is to change the focus of students from scoring marks to learning the content particularly at the beginning of the programme while teaching fundamental courses. In this paper, the authors made an attempt to compare two strategies of teaching and learning; the Broiler Chicken Nourishing (BCN) verses the Desi Chicken Nourishing (DCN) in an Indian perspective. The BCN strategy shows only a short term and narrow goal though productive, it was in DCN strategy there is effective knowledge transfer which promotes more of self learning and self realization. A case study was done on Electric Circuit Analysis for second semester Electrical Engineering students. The analysis shows that DCN is more learner centered and yields fruitful results when compared to BCN. The DCN approach promotes original thinking of the students and develops good interpersonal skill.Keywords

Based on recent case studies, the faculties in engineering college are facing more struggle because how to make students to understand the concept clearly. So many faculties are failed to reach the students as facilitator. In some studies, students understand the concept which was taught by faculties, but fail to reproduce or remember the fundamentals during assessment period. In this paper, the improved teaching method for students to understand the concepts and remember the fundamentals through Active learning techniques (ALT).
Here the techniques which explain the student's entertainments like games, puzzles, quiz, peer-to-peer learning and demonstration that are converted into education methods. Also few innovative ideas are implemented and examined on students. The active learning questionnaires, activities of students and experience over the activities are explained with the help of case studies, by taking two batch (2014&2016 – electrical machine course) of students and their performance are compared with and without the activities using active learning techniques. The comparison will be based on Blooms taxonomy assessment pattern results. However, the improvement of student's communications, selfconfidence level, interest towards the course, perspective thinking, team work, knowledge over the concept and course fundamentals are explained through these results.

Flipped Classroom (FC) or Inverted Classroom is now an important area of focus in educational studies which is supposed to promote critical thinking inside classroom providing time for learner-centered activities such as active and problem-based learning. There is a lack of skills and awareness in implementing FC in Engineering Education. This paper illustrates an effort in implementing FC based teaching - learning process and assessment methodologies using Information and Communications Technology (ICT) tools to achieve the course outcomes for an elective course 'Soft Computing'. The outcomes are obtained for two different set of students, where one set undergoes FC with ICT tools, second set undergoes traditional classroom. The student outcomes are discussed in terms of their exam and assignment marks and their satisfactory index towards the course. It is obvious from the case study that satisfactory index is high for the students who were taught based on FC where there is proper planning which is implemented using ICT tools.Keywords

In this paper, a problem of allocation and sizing of multiple active power-line conditioners (aplcs) in power systems is handled with novel formulation. The utilized objective function comprises two main factors such as reduction of total harmonic distortion and the total cost of active power-line conditioners (aplcs). The formulated problem is solved by optimization technique Shuffle Frog Leap Algorithm (SHFLA) using MATLABTM. To evaluate the competence of the proposed formulation, the IEEE 18-bus distorted distribution test system is employed and investigated with various number of aplcs placement. These cases are based on the discrete and limited size for aplcs, requiring the optimization method to solve the constrained and discrete nonlinear problems. The comparison of results in this paper showed that the proposed SHFLA is the most effective result among others in determining optimum location and size of APLC in distribution systems.Keywords

Vehicles running on oil have to change over in next few decades to alternatives which could be hydrogen, electricity. World over, almost all the major players in the automobile industry have introduced electric vehicles (EV) or Plug-in Hybrid Electric vehicle (PHEV) in the market. This is rather in response to their commitment to a green environment, reducing carbon footprints and reducing the emission rates. With the unveiling of the National Electric Mobility Mission Plan 2020, by the government of India manufacturers are urged to adopt electric vehicles in an attempt to reduce our dependence on imported oil. The ambitious plan aims to produce 6–7 million electric vehicles by 2020 with an estimated fuel saving of 2.2–2.5 million tonnes of oil. Electric vehicles when utilized for feeding back the energy to the grid play a very important role in Demand response in Smart grid environment. This will play a major role in the Power sector scenario. Though this technology is yet to pick up in India, it has become popular in the western countries. Lot of Research work has been carried out and research work has been published, which is reviewed in this paper.Keywords

This study examines the use of internet as a tool for corporate reporting and the extent to which Indian firms disclose financial information through the internet. The disclosure of information on the internet is examined through a disclosure index. A sample of 136 listed firms, from different sectors was examined for the purpose of the study. The results of the study indicate that industry sector had a significant relationship to the extent of financial disclosures on the websites. The study also found that only few firms had used websites to disclose extensive financial information. The most reported information was the quarterly results, whereas information about performance was the least disclosed. The paper suggests that Indian firms can improve disclosures in the websites to improve transparency.Keywords

Online teaching, an inevitable part of education in 2020, has its own advantages and disadvantages with respect to the perspectives of student and teachers. Every teacher has been in a situation to transform suddenly to the fluctuating needs of education in the COVID 19 crisis. Is this transformation quick and easy for all the teachers? This is an important question that may depend on number of factors including teachers’ teaching experience, economic and social background, and skills in teaching tools, motivation and attitude. This research study looks into the parameter “Teaching experience” and attempts to find whether teaching experience stands as an influencing factor in the transformation process. As learning new is always easier than unlearning, this parameter is critically important in analysing whether the long-time experience affects the rate of transformation to online teaching. The research is conducted as a qualitative research with surveys obtained from students and faculty of the host institution after the first cycle of online teaching (after May 2020). 66 teachers and 215 students from various engineering disciplines participated in the survey. Observations from the survey are analysed in different elements of online learning. This study compares the expectations of students and the preference of teachers in these elements. From the study, it has been inferred that teaching experience has a significant impact on the transformation of teachers to meet the students’ expectations in the perspective of online teaching. The study also enables suitable recommendations for need based training programs.Keywords

Assessment of collaborative activities comprises two important elements: group assessment and individual assessment. This research study explores specific methods for assessing the individual students in online collaborative/cooperative activity and analyzes the efficiency in terms of student learning. An online collaborative activity based on the Student Groups Achievement Division (STAD) method has been planned and implemented for the undergraduate third semester Engineering students (n=71). The activity has been designed in such a way that the students perform the activity through the collaborative features of the Learning Management Systems (LMS) such as group projects and discussions. Group assessment is measured with discussions and group report writing while the individual assessment is measured through quizzes, tests and activity journals. The scores for the quiz and activity journal are taken into account to measure the student learning. These scores are compared against their performance scores in the summative examination. From the observations by comparing the scores, it is found that these strategies measure the individual learning effectively such that they fall in linear with the formal examination marks. Also, feedback is obtained from the students to ensure their satisfaction in individual assessment. Success index for the activity based on students' feedback is calculated using weighted likert scale and found to be 0.811 (Ideal index =1) which is an appreciable score.Keywords
