Covid PDS Plus: An E-PDS & Healthcare Platform Towards Pandemic Restoration
Get PDFDuring the COVID-19 crisis, millions of migrants daily-wage workers and homeless people around the world are facing food insecurity. This has forced migrants to travel to their hometowns during the pandemic thereby exposing them to greater health risks and also accelerating the risk of spread of virus. Anecdotal evidence demonstrates the importance of enforcing food security and distribution policies to tide the crisis. However, the effects of these policies on containing mobility during the crisis remain unknown. This paper presents a prototype of technology enabled e-PDS (pubic distribution system) and healthcare platform to connect different stakeholders i.e. people, government, NGOs
Design of Composite Shear Wall Encased with Vertical Steel Profiles
Get PDFThe 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
Seismic Isolation of Building-Equipment System Using Modified Variable Friction Pendulum System
Get PDFIn 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
Comparative Study of Seismic Analysis of Pier Supported on Pile as per IRC:6-2017 and IRC SP:114-2018
Get PDFThis 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
Mobile Learning: An Approach to Improve the Quantity of Educational Attainment in Conflict Hit Areas Like J&K
Get PDFMobile 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
An Experimental Study on Ground Improvement by Application of Fly Ash and Lime on Clayey and Sandy Soil
Get PDFConstruction 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

Scrum: An Agile Software Development Process and Metrics
Get PDFIn 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

Using the Technology Acceptance Model to Understand the Use of Bring Your Own Device (BYOD) to Classroom
Get PDFIn 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
