One of the important aspects of the outcome based Education (OBE) is the assessment of course outcomes (CO). As we have adopted the OBE framework for our programme. we have integrated the theory and laboratory course and conducted activities to achieve the course outcome of Computer Network course. As we know the tollgate courses have multiple prerequisite courses and to attain the course outcome the learning of these prerequisite courses can be applied in this course. The union of the attainment of the outcome sets of all the tollgate courses can be viewed as program outcome attainment. Fundamentally any tollgate course is progressive in the attainment of the outcomes. A Computer Network is one such toll gate course for computer science and engineering programme positioned during the sixth semester. The concepts of basic subjects like data structures, algorithms, object oriented programming, operating system are prerequisites which are used to solve a large problem.
The authors have attempted to measure the outcomes of this tollgate course through theory and laboratory activities. One activity on the client server computational overview was tried to address the issues related to fault tolerant systems. Other activity defined to understand the network behavior for given parameters to apply the statistical techniques for the simulated results.

New directions are brought into teaching-learning process due to the recent advances in technology and change of students learning styles. As there is increasing in tuition costs and need of time management created space for online courses and flipped classrooms in the education system. Main challenge in teaching a course for Final year is, motivating all students to attend classes regularly and participate in the discussion. As they will be busy with placement activities, project development and training in industries, faculty need to use the class time, efficiently and deliver required course contents to the students. A new pedagogical tool flipped classroom is adopted to address these issues, which employs asynchronous video lectures and practice problems as homework, and active, group-based problem solving activities in the classroom. It represents a unique combinations of learning theories to teach a course. In this paper authors present a comprehensive method of using flipped classroom to teach a Distributed Computing System to final year Computer Science and Engineering graduate students. This paper focuses on type of in-class and out-of-class activities, the measures used to evaluate different activities and methodological characteristics for each activity defined for the course. Result of students' feedback talks about the positive aspect of the framework adopted.Keywords

An entrant to engineering has to undergo many fundamental courses in the first year of curriculum. Basic electrical engineering is one amongst these courses. The traditional way of teaching the course was teacher-centric and aid used for teaching was chalk and talk. Less emphasis was given for student interaction. Traditional style of teaching rarely gives students the opportunity to apply their newfound knowledge to actual situations, resulting in a serious time lag between students learning and applying new knowledge. As a result many students have trouble determining the relevance of what they are being taught, and thus lacking any obvious need to learn and fail to engage in the learning process. To provide an opportunity for collaborative experiential learning to reinforce the theoretical concepts imbibed in students we proposed a model on collaborative experiential learning which concentrates on the beginning of instruction referring to Fink's Model containing Knowledge of subject matter, Design of Course, Teacher-student interaction and Course management. In particular, the "Teacher-student interaction" is adopted which is an umbrella term that refers to all the different ways teachers interact with their students. For better interfacing, Kolb's experiential learning theory based on a four-stage learning cycle is applied. In addition to the above interaction in teaching learning process learning style of an individual is important to undergo different learning cycle. The three main types of learning styles are, auditory, visual, and kinesthetic. Whenever the task is given for an individual the above learning styles can be adopted, meanwhile if the task is for a team with different learning style of a student then we need to focus on style of learning. The three styles of learning are active learning, cooperative learning and problem based learning. The proposed model is applied to the course on Fundamentals of Electrical Engineering, Apart from the regular classroom teaching we used principles of instruction to select, plan and develop an activity based on Industry visit to enhance students learning. To realize the impact of learning happened through the industry visit pertaining to topics like actuators and/or sensors, the written examination was conducted and feedback at two intervals, before and after the industry visit was taken. Individual question wise inferential statistical analysis using paired t- test was performed and inferred that the activity improved the knowledge and exposure level of a student.Keywords

One of the common difficulties faced by an entrant of an undergraduate course studying Electrical Engineering is in understanding the fundamentals of Alternating circuits (a.c.). In order to address the identified difficulty, modern engineering tool was introduced to enhance the learning in a.c. circuits as simulation tool plays an important role within the frame of teaching and learning in education across the world. With the performance of students in continuous internal examination (CIE) being less, there was a need to improvise their understanding the concepts of a.c. circuit, hence this activity was planned and implemented. The activity was initiated with the introduction to Personal computer Simulation Program with Integrated Circuit Emphasis (PSPICE) simulation tool. Simulation tool was applied in designing structured learning experiences and it was targeted to enhance teamwork competencies and understand the fundamentals of a.c. circuits. Students were trained to simulate complete and well-formed circuits which helped their learning environment suitable for supplementing traditional method of chalk and talk instruction. The activity was concluded by a feedback survey to measure the effectiveness of learning through simulation assignment on teaching&learning process in regular curriculum. The response from the students' feedback showed that they were more satisfied with simulation assignment compared to conventional one; it helped them to understand theoretical concepts better. It also showed increased involvement in learning during the activity. The performance in CIE was compared with semester end examination (SEE), and it was found that the students' performance in SEE showed significant improvements in understanding the concepts of a.c. circuits. The work presented in this paper summarizes the effectiveness of simulation package used in enhancing teaching and learning in fundamental course of electrical engineering.Keywords

Background/Objectives: To have a sustainable and low carbon living, efficient use of renewable energy is necessary hence, a power converter with less switching loss is proposed for the improvement of efficiency of proposed system. Methods/Statistical Analysis: In this work a dc boost converter is considered using an auxiliary resonant circuit for implementation of soft switching technology to reduce switching loss in the converter. The proposed dc resonant boost converter is designed for a required dc output based on the gate duty cycle. The soft switching is made possible by suitably designing the values of the inductor and capacitor of the dc resonant circuit. This circuit is simulated with MATLAB software. Findings: The resonant dc boost converter was simulated using MATLAB software with hard switching, the results of the simulation is discussed with waveforms and numerical values. The soft switched converter was able to provide an improved output voltage of 2Volts, current of 0.4 A, compared to the conventionally designed converter. Suitable design of the resonant components namely the inductor and capacitor, the efficiency of the soft-switched resonant boost converter improved by 2% compared to hard switched converter. Both the hard switching and soft-switched converters were simulated in open loop. It is evident from the output voltage and current waveforms, the settling time taken by the soft-switched converter is more compared to hard switched converter, but the improvement in voltage profile, current profile and efficiency overcomes the drawback of increased settling time. The resonant soft-switched converter when compared with the other converters reported provides an improved performance hence very much suitable for solar photovoltaic application. Applications/Improvements: The performance of the soft-switched converter can be improved further through closed loop control with simple controllers or using fuzzy logic controllers. This converter can also be used for other sources in any distributed generation.Keywords

Wound healing is a complex dynamic process that results in the restoration of anatomic continuity and function. The present study has proved that the wound healing potential of ethanolic extract obtained from ischolar_mains of Phyllanthus simplex Retz showed a significant effect than the same extract obtained from other parts of the plant. That extract showed a facilitatory epithelisation and wound contraction than other parts extracts. The ischolar_main extract animal groups showed a high collagen content than other extracts and the control groups. Hexosamine content and ascorbic acid levels showed an increased level of the extract. Ascorbic acid is reported to have scavenging activity and inhibition of lipid peroxidation, which helps to show a better healing effect for the test groups.

Explosive growth of Computer network technologies and use of these technologies have led a new thinking for researcher. In recent days the research focus in network domain is on areas like, Performance measurement of broadband and mobile access networks, Censorship measurement and circumvention, Software-defined networking (SDN), Internet of Things (IoT) security. This has created a challenge to the academicians to make students think towards these research fields and to adopt activity based teaching learning techniques to deliver the basics as well as the advanced concepts of computer network. As most of the students are visual learner teaching computer networking principles can be enhanced using simulation through the use of interactive simulation. With networking simulation tools, students can construct, tune, and analyze network performance while reinforcing their understanding of networking theory.
The course expects the students should have an ability to understand the concepts, design and analyze the performance of the network. Experience of authors says that have an ability to understand the network concepts but they lack in analysis. So authors have put effort to address the lacunae. The activity has been designed by integrating theory and laboratory course on computer network which focuses on network traffic analysis by applying the concepts learnt. Wire Shark traffic analysis tool is used by students to capture the real time data and analyze the data for the selected network protocol. The paper discusses the design, conduction of activity, in computer network course focusing on analysis on network traffic which in turn created a space to think on research related to the network domain. Through this activity we could attain course outcome 3 and Program outcome (PO) 4 and 5 which is more than 80%.

Modified 9Cr-1Mo steel is extensively used for high temperature applications due to its good thermo-physical, weldability, fabricability and high temperature properties. While Type IV cracking is of concern during service of weld joints, toughness of its weldmetal is an important consideration during qualification of weld joints, especially for those made by SMAW process. The weldmetal toughness is significantly influenced by deposition process and sequence, and temperature and duration of PWHT. For a special-purpose mod.9Cr-1Mo steel weldmetal, containing intentional addition of 2.4wt% of nickel and manganese, the A and A transformation temperatures, calculated using ThermoCalc software, was found as 945 and 1065K, respectively. To understand its tempering behavior, the weldmetal was subjected to PWHT at 1013, 1033 and 1053K for different durations. The weldmetal hardness decreased significantly on PWHT at 1013K compared to that at 1033 and 1053K. The weldmetal toughness increased monotonically with PWHT temperature; from 27J for 923K PWHT to 32J and 132J for 973K and 1023K PWHTs, respectively, and then decreased marginally to 113J on PWHT at 1153K. These results suggested formation of fresh martensite during PWHT at 1053K. Bright-field transmission electron microscopic examination revealed formation of lath martensite in the weldmetal, with the lath sizes being finer than those reported in other mod. 9Cr-1Mo steel weldmetal prepared using similar process. Hence, detailed microstructural analyses was carried out to investigate this anomalous variation in mechanical properties, as also to study the effect of temperature and duration of PWHT on the microstructure and toughness of this modified 9Cr-1Mo steel weldmetal.- Effect of Heat Treatment on the Microstructure and Microchemistry of Explosive Welded Joints of Ti-5Ta-1.8Nb and 304L SS

Explosive welding process was used for joining Ti-5Ta-1.8Nb alloy to 304L austenitic stainless steel to avoid the formation of intermetallic phases at the interface which otherwise form in fusion welding processes. Both X-ray diffraction and electron microprobe based analysis showed the absence of intermetallic phases at the weld interface within their detection limits. Strain induced phase transformation due to the deformation induced by explosive welding was observed in both the base materials. The 'as received' explosive joints were further heat treated at 873 and 1073 K for durations in the range of 1 to 20 h to select appropriate temperature for further processing subsequent to welding. Detailed analysis using electron microprobe showed considerable microstructural and micro chemical modification at the weld interface due to inter-diffusion of Fe, Ti, Cr and Ni. The width and number of reaction zones varied as a function of heat treatment temperature and time. From the experiments, it was inferred that even the lowest temperature-time combination, i.e. 873 K-1h, is not suitable for heat treatment of explosive joints of Ti-5Ta-1.8Nb/SS 304L, and further lowering of the process temperature is required.Keywords

Software process standards and models provide best set of practices and guidelines to improve the quality of the software process and products resulting from that process. These software models however, do not advise following a particular software development methodology, and consequently, software development teams face problems with respect to compliance between the selected process development strategy and the one actually pursued. In this report, the current software process models used in academia and their transition to newer, more advanced models are studied. The main focus although, is on transition from the hugely popular process model followed in academia, Waterfall model to Agile model.Keywords
