Abstract:
Prolonged school closures due to COVID-19 pushed the education system at all levels of India to the limits where structural weaknesses and other loopholes can be clearly visible. The significant challenges like lack of ICT infrastructure and digital competence of teachers, played an important role in the acceptance of new modes of teaching. Creating and delivering the educational content by using digital tools still remains a daunting task for many teachers. At the same time parents are overwhelmed with the burden to teach children at home and help them with online learning and bearing extra expenses of digital devices and internet services. Students, on the other hand, are struggling continually to adapt to a new learning environment that offers some flexibility along with some challenges. This study aims to present the challenges faced in instant migration of offline to online mode of teaching-learning by the stakeholders.

Abstract:
Many of the private universities of Bangladesh have decided to continue their academic activities through online off-campus learning amid concerns that traditional classes could spread the COVID-19 virus. Teaching is moving online, on an untested and unprecedented scale. There are challenges and possibilities unveiling in the technical tertiary level education like Architecture. A Bachelor of Architecture (B.Arch) programme need to be comprising of both theory and sessional studio courses. The learning modes are not same for these two areas. Modification and new invention of teaching methods need to be introduced to coping of off-campus class. In this study, the first-hand experience of on-line teaching in B.Arch program of the author and the similar experience of faculties of the different universities of Bangladesh are triangulated to come up with a model of off-campus class. This article finds out the systematic process of teaching method to coping of off-campus class during the COVID-19 crisis for the Architecture pedagogy. The process has three domains and four major areas. The teacher’s domain and the student’s domain are connected through the domain of virtual classroom. The four major areas are live streaming, live discourse, prerecorded lecture and assignment and feedback.

Abstract:
An increase in the risk of COVID-19 spread led people, industries and the government to adopt various approaches for controlling the transmission rate of COVID-19 viruses. Although each approach has its advantages, but in terms of cost-effectiveness and flexibility, one approach i.e. Arduino based sanitizing systems have played an important role to prevent the coronavirus from spreading. In the direction of this research field, a lot of researchers have exerted great efforts to control the COVID-19 outbreak. However, an automatic door handle and knob sanitizer based on IR sensor and servo motor has not been reported till date as per our knowledge. Therefore, In this paper, we have demonstrated an automatic door handle sanitizer to sanitize the handle or knob of a door that is generally used by many people in houses, hospitals, and industries, etc. The reported work has been done to prevent people from getting infected by the coronavirus. If anyone gets infected by touching the contaminated door knob of any institution, house, hospital, etc., then it will have a severe effect on the person as well as on his country. In this regard, the reported system sanitizes the door handle to remove the virus from it as the person touches the door knob. The demonstrated system contains Arduino-Nano, Servo motor, Bread-board and an IR Sensor. It can be implemented in public places such as hospitals, companies where the doors are used frequently to break the chain of COVID-19 infection.

Abstract:
Mobile Learning: An Approach to Improve the Quantity of Educational Attainment in Conflict Hit Areas Like J&K The days are gone when mobile was considered a big distraction in the study. We can make best use of mobile in achieving educational attributes by improving both quantity and quality of education and this approach is simply called mobile learning. This paper presents an outlook of making best use of mobile learning to increase the educational attainment, especially in conflict hit areas, where strikes, curfew and processions, demonstrations become the hurdle in the normal working hours in the educational system. Here we have taken an example of Jammu and Kashmir, where the security climate is vulnerable from last more than thirty years and peace is a major concern at present. In this situation a fear among the student community to go schools has risen to a level, which ultimately affects the education system badly. In most of the cases, the syllabus is not completed in the schools due to shortage of effective class hours. To tackle this situation, the mobile learning could be the best remedial measure to address this issue.

Abstract:
Construction on locally available clayey soil is often problematic due to its swelling and shrinkage nature. Pavements are most affected as the upthrust due to regional swelling of clayey soil during monsoon season and shrinking during dry season causes unwanted cracks in the pavement. As a consequence, the pavement gets damaged. In places having extensive deposit of clayey soil, soil replacement becomes time-consuming and uneconomical. Hence the clayey soil to be considered as subgrade needs to be pre-treated. Fly ash, an industrial waste can be used for such treatment. To improve the engineering properties of on-site available clayey soil and sandy soil with lime and fly ash was studied. Based on the results obtained from experiments the suitability of fly ash and lime to be considered as additives to improve local clayey and sandy soil properties has been analyzed. It was observed that the on the addition of fly ash within 40-60% range can be satisfactorily used to replace the local clayey soil and fly ash percentage within 20-40% can be used to replace the local sand. Lime content in the range of 4-8% can be satisfactorily used in both in situ available soil and local sand with fly ash mixtures for the improvement of strength in terms of shear strength as well as CBR value.

Abstract:
In a traditional software development process such as the Waterfall Model, works best in a stable environment. But, it is not flexible when it comes to change. There is a gap in the interaction between the users and the development team which leads to incomplete and misunderstood specification. Because of this, the end product is sometimes a surprise to users and this gap accelerates incorrect development of the software product. Once requirements are frozen there is no scope of accepting changes. There is a need for a framework which holds the solution for all these situations. With this premise, the agile development methodology came into existence. Scrum, an agile approach supports continuous collaboration among the customer, team members, and other stakeholders. Its time-boxed approach and continuous feedback from the product owner ensures the development of working product with essential features at all the time. This paper explains the agile software development approach, its proclamation and different frameworks of agile approach. Further illustrate most widely used framework: Scrum. This research paper covers the implementation and application of Scrum. It focuses on why Scrum is preferred over the Waterfall Model with the help of some survey results and later a discussion on some Scrum Metrics which will be helpful and accounting for the best Scrum Practices in achieving goals set by the software development team, the product owner and the customers. The outcome of this study shows that Scrum Metrics is critical and highly valuable for successful product development. The quantitative insight that these metrics provide for the Scrum Team, Product Owner and Stakeholders is necessary for achieving strong project dynamics and optimal results.

Abstract:
The concept of steel-concrete composite shear wall is introduced due to the benefits achieved by integrating both the materials. These are structural walls, where steel profiles are encased at the boundary elements. Due to their higher lateral strength and stiffness, they offer a good alternative to improve earthquake resistance over conventional reinforced concrete shear walls in medium and high-rise buildings. Current literature shows that, design procedure of such composite shear walls is not addressed in developing country codes. Hence, a design of steel-concrete composite shear wall is proposed in the present paper on the basis of existing theory and with the help of standard codes. The web portion of shear wall has to be designed as per provisions of Eurocode 8. For the design of composite boundary elements, design norms of composite columns are followed. Also the design of shear stud connectors is adopted according to Eurocode 4.

Abstract:
In this study, building-equipment system with Modified Variable Friction Pendulum System (MVFPS) is investigated under different earthquake ground excitations. Earthquake response of building-equipment system isolated with MVFPS is compared with Variable Friction Pendulum System (VFPS) and Friction Pendulum System (FPS) in order to find efficiency of MVFPS. Newmark’s linear acceleration method is used for solving governing equation of motion for building-equipment system. In this investigation, different storey buildings are considered. It is observed that MVFPS is more efficient in reducing the recoverable energy than FPS, but less efficient than VFPS. From the comparative study, it is found that FPS shows robust performance in comparison to MVFPS and VFPS in reducing equipment acceleration and displacement.

Abstract:
This paper depicts the study of seismic analysis of reinforced concrete bridge piers as per provisions of Indian Road Congress (IRC) guidelines. Bridges are designed having two main structural elements named – “Superstructure” and “Substructure”. Superstructure consists of deck and supporting girder/truss system below deck. Substructure includes Abutments, Piers, Portals and Foundations. Amongst these, Abutments/Piers are crucial part of bridge. Therefore, as per the seismic design philosophy, it is necessary to study the seismic behaviour of bridge piers. With the advancements in technology and subsequent researches in Infrastructure fields, IRC guidelines are updated and revised time-to-time. Introduction of IRC SP:114-2018 guideline for earthquake forces in bridges is an example of such developments. In this research, seismic analysis of Reinforced Cement Concrete (RCC) bridge pier is carried out as per provisions of prevailing guideline IRC:6-2017. Base shear value of IRC:6-2017 is compared with IRC SP:114-2018 which now supersedes seismic provisions of IRC:6-2017. For analysis, different span lengths of 25 m, 30 m and 36 m are used. To assess the impact of height of piers in earthquake analysis, various pier heights such as 10 m, 20 m and 30 m are assumed. The analysis is carried out as per Elastic Seismic Acceleration Method with consideration of different zones and importance of the bridge as per IRC guidelines. Effect of vertical ground motion is also considered in analysis. From analysis, it is observed that base shear and vertical forces have been increased remarkably as per IRC SP:114-2018 compared to IRC:6-2017.

Abstract:
Natural building materials are diminishing day by day. Hence economical alternatives of natural building materials are necessary for sustainable development. Hollow concrete block was developed to reduce the use of natural building materials. Agricultural waste products like coconut shells from coconut industry have disposal problems causing environmental concerns. Various studies were done in the past, replacing a portion of the natural aggregates with broken coconut shells for manufacturing the hollow concrete blocks. In this study, we have developed a new method of forming the holes of hollow concrete blocks by placing stacks of half portion of coconut shells at the bottom with convex surface upwards to reinforce the holes by arch action. The results show that the coconut shell reinforced hollow concrete blocks have better strength as compared to open-graded hollow concrete blocks available in the market.

Abstract:
In today’s world, the technology has been embedded in all aspects of human life. The education sector has been at the forefront of technology adoption. Technology-enhanced learning (TEL) is a system of education that promotes the application of information and communication technology for teaching and learning and the concept of “bring your own device” (BYOD) supports this. BYOD is particularly beneficial for the education sector due to cost saving and comfort of using personal devices. Researchers believe that inclusion of technology must be supported by the user acceptance and the most popular framework to predict user acceptance of technology is the Technology Acceptance Model (TAM) proposed by Davis. The paper describes the study conducted for the purpose of predicting the acceptance and utilization of BYOD by the college students based on TAM variables of perceived ease of use, perceived usefulness, attitude towards using, and behavioral intention to use. Additional external variables of teachers’ influence, facilitating conditions and peer influence are adopted to study the user acceptance of BYOD. A questionnaire based on the TAM variables was developed and used to gather information from students of a post graduate course in information technology of an Indian university. The results of analysis suggest that the considered variables have an impact on the overall behavioral intention to use BYOD and thus support the original findings of TAM.

Abstract:
A paradigm shift has been observed from ‘moving of vehicles’ to ‘moving of persons’ while planning for transportation facilities in cities. Provision of integrated and barrier free pedestrian facilities is essential to ensure inclusive mobility. Pedestrian facilities are a critical component in producing a pedestrianfriendly environment. In India, the present facilities provided for the pedestrians are not efficient in general and crosswalks (zebra crossings) in particular. The pedestrian casualties in India have registered an increase of 11.7 percent in the year 2017, of which 31 percent have occurred on crosswalks. Therefore, an attempt has been made to overview the level of safety provided on the crosswalks. It has been found that majority of crosswalks are not fulfilling their intended purposes due to improper signage and markings, inadequate maintenance and bad surface condition. Another significant reason hampering the safety of pedestrians at crosswalks has been found to be inappropriate provision of guardrails and pedestrian refuge islands. Hence, some measures have been suggested to augment the pedestrian safety on the crosswalks.

Abstract:
This work proposes an algorithm that uses paths based on tile segmentation to build complex clusters. After allocating data items (points) to geometric shapes in tile format, the complexity of our algorithm is related to the number of tiles instead of the number of points. The main novelty is the way our algorithm goes through the grids, saving time and providing good results. It does not demand any configuration parameters from users, making easier to use than other strategies. Besides, the algorithm does not create overlapping clusters, which simplifies the interpretation of results.

Construction industry relies heavily on conventional material such as cement, sand and gravel for the production of concrete The river sand and gravels which are most commonly used as fine aggregates and coarse aggregates respectively in the production of concrete, poses the problem of acute shortage in many areas, whose continued use has started posing serious problem with respect to its availability, cost and environmental impact. Attempt is being made in this project to use the locally available waste materials to replace the river sand and gravels to produce light weight and low cost concrete. Sawdust and Brick ballast are easily affordable at low costs, which are partially replaces with river sand and gravels respectively for making concrete. Natural sand and Gravels have been partially replaced (4% SD 8% BB, 4% SD 16% BB, 4% SD 24% BB, 8% SD 8% BB, 8% SD 16% BB, 8% SD 24% BB, 12% SD 8% BB, 12% SD 16% BB and 12% SD 24% BB. by using M30 grade of concrete) with sawdust and broken brick ballast respectively. For this, thirty concrete cubes of size 150mm X 150mm X 150mm have been casted and water cement ratio of 0.42 has been used. Water reducing admixture is used to increase the workability. Slump test, Compacting factor test and compressive strength at (28 days) of specimens having above combinations have been compared with control specimens. The workability and compressive strength gradually decreases for the increasing the replacement percentages. The optimum mix found to produce M30 grade of concrete is 8% of sawdust and 16% of Brick ballast.

Abstract:
Wave energy is the most available energy associated in deep water seas and oceans. Therefore, many attempts have been applied to capture these energies. This paper describes the design, construction and testing of water wave flume. The water wave flume contains an electromechanically driven rotor type wave maker to generate water wave powers. The waves are constructed by different sizes and arrangements of blades which are connected to the rotor. The rotor is driven by an ac motor to generate wave. At the end of the tank a force measuring device is attached opposite to the rotor to measure the thrust of the wave. Experimental results are validated with available literature and wave theory. The results also show that the width of the blade play major role in generating wave sizes including frequency, amplitude and the power. Wider blade displaces much water to generate wave but reduces the blade speed.

Abstract:
Investigations were carried out on the changes in properties of concrete when steel slag is used in concrete in its normal form and after modifying its properties by infusing it with nano-silica. The sand is replaced by steel slag and modified steel slag by 10%, 20% and 30% in M30 grade concrete. Tests results on compressive strength and workability of concrete revealed that compressive strength of concrete cubes after 28 days increased by 25.4%, 26.4% and 45.2% for 10%, 20% and 30% respectively after replacing sand by steel slag. After modification of steel slag properties by infusing it with nano silica, the 28 days compressive strength was observed to be increased by 38.19%, 35.80% and 27.89% for 10%, 20% and 30% as compared to traditional concrete mix respectively after replacement. Infusing steel slag with nano silica increased the compressive strength of concrete mix by 20.17%, 25.74% and 49.64% for 10%, 20% and 30% respectively when compared to normal steel slag concrete mix. It was also observed that using steel slag in concrete mix also influences on water consumption in concrete mix. Workability tests conducted using 0.45 and 0.5 w/c ratio and the inference was that the workability increased with the increase in percentage of steel slag but workability decreases with the increase in percentage of modified steel slag.

Abstract:
Educational data mining is the procedure of converting raw data collected from educational databases into some useful information. It can be helpful in designing and answering research questions like performance prediction of students in academics, factors that affect the students’ performance, help the teachers in understanding the problems faced by the students to understand the course content and complexity of the subject taken so that the teachers can take timely action to control the dropout rate. This also includes improving the teaching learning process so that the interventions can be taken at the right time to improve the performance of the student. This paper is the review of the research work done in the field of educational data mining for the prediction of students’ performance. The factors that influence the performance of the students i.e. the type of classrooms they attend such as traditional or on-line, socio-economic, educational background of the family, attitude toward studies and challenges faced by the students during course progress. These factors leads to the categorization of the students into three groups “Low-Risk”: who have High probability of succeeding, “Medium-Risk”: who may succeed in their examination, “High-Risk”: who have High probability of failing or drop-out. It elaborates the different ways to improve the teaching learning process by providing the students personal assistance, notes, class-assignments and special class tests. The most efficient techniques that are used in educational data mining are also reviewed such as; classification, regression, clustering and and prediction.

Abstract:
One of the key educational notions measured in the National Student Survey (NSS) is intellectual stimulation. This study aimed to find out Higher Education (HE) engineering students’ views of intellectual stimulation with a focus on its measurement and supporting its increase within the classroom environment. A quantitative questionnaire acted as a data gathering instrument. The sample comprised 128 students from Edinburgh Napier University (ENU), Scotland. The survey findings showed a positive correlation and positive agreement between the intellectual stimulation (IS), intrinsic motivation (IM) and deep learning approach (DLA) scales. The students’ feedback suggests that implementation of the new intellectual scale based teaching and learning strategy is useful in intellectually stimulated the students and encouraged them to adopt deep learning approach. The findings suggest the design of an intellectually stimulating environment in HE classroom, should consider students’ learning styles, challenge students, allow the provision of timely feedback and provide opportunities to encourage independent thought. Further, the research suggests, the studied institution should encourage staff to consider the intellectual stimulation scale when constructively aligning learning and teaching with an assessment.

Abstract:
The paper provides insight into various swarm intelligence based routing protocols for Internet of Things (IoT), which are currently available for the Mobile Ad-hoc networks (MANETs) and wireless sensor networks (WSNs). There are several issues which are limiting the growth of Internet of Things. These include the reliability, link failures, routing, heterogeneity etc. The MANETs and WSNs routing issues impose almost same requirements for IoT routing mechanism. The recent work of the worldwide researchers is focused on this area. protocols are based on the principles of swarm intelligence. The swarm intelligence is applied to achieve the optimality and the efficiency in solving the complex, multi-hop and dynamic requirements of the wireless networks. The application of the ACO technique tries to provide answers to many routing issues. Using the swarm intelligence and ant colony optimization principles, it has been seen that, the protocols’ efficiency definitely increases and also provides more scope for the development of more robust, reliable and efficient routing protocols for the IoT. As the various standard protocols available for MANETs and WSNs are not reliable enough, the paper finds the need of some efficient routing algorithms for IoT.

Abstract:
Cloud computing is the concern of computer hardware and software resources above the internet so that anyone who is connected to the internet can access it as a service or provision in a seamless way. As we are moving more and more towards the application of this newly emerging technology, it is essential to study, evaluate and analyze the performance, security and other related problems that might be encountered in cloud computing. Since, it is not a practicable way to directly examine the behavior of cloud on such problems using the real hardware and software resources due to its high costs, modeling and simulation has become an essential tool to withstand with these issues. In this paper, we retrospect, analyse and compare features of the existing cloud computing simulators and various location based authentication and simulation tools.

Abstract:
In a last few decades there has been tremendous growth and a drastic rise in wireless communication technologies. The major issue that the world is facing today with the advent of so many sophisticated wireless communication devices is efficient utilization of the spectrum. Spectrum efficiency comes together with a tradeoff factor of energy consumption. Thus, the need of the hour is an energy and bandwidth efficient technique. DS-CDMA is one of the competitive and most investigated technique in wireless communication which caters the large demand at the same time with limited bandwidth. Existing modulation techniques does not promise to provide better performance in case of higher noise. Therefore, one looks for a better BER stipulated modulation format to improve and enhance the performance of the system. This article revisits conventional Binary phase shift keying method and compares its performance in terms of BER with a special Extended Binary Phase Shift Keying (EBPSK) modulation format for a DS- CDMA system. EBPSK scheme is flexible and simple which is easily integrated in a network and assures improved and enhanced performance.
