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.

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.

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.

The paper highlight characteristics of no fine concrete (NFC) by evaluating and interpreting the research work undertaken by research scholars around world in past. It explains the approach for better performances. It helps to understand and identify the difference between knowledge and actual performance on ground which stops it from wide and acceptable application throughout the globe. A comprehensive investigation of proportioning of no fine Concrete has been discussed. Identification of relationship between mechanical properties with its design and pore structure of NFC will help us in studying ways of its better utilization. The specific reference has been made for India to understand level of research & development in laboratories and status of different applications at different levels.

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.

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.

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.

Extensive study is carried out to ascertain the effects of various construction practices on the bond strength between different layers of the pavement. In this study various construction practices refers to curing time of the pavement, various equipments used during construction of pavement, surface treatment provided. In this study a review is also carried out of the research work carried out by various researchers for estimating the bond strength between the existing old hot mix asphalt (HMA) layer and the new hot mix asphalt (HMA) layer overlaid. Also a review is taken in study regarding various experiments conducted by the researchers on the bond strength of different layers. Normally milling provides a good strength and good bond at the interface between the old layer and new layer overlaid on it. It is also observed that curing time has least effect on the bond strength.

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.
