Item Water resources systems planning and management problems(BITS, Pilani, 1998-01-01) Devi Prasad, T.Item Multi Criteria Decision Analysis and Modeling for Water Quality Management in a River Basin(BITS Pilani, 2018) Srinivas, RThe present-day problems of rapid and uncontrolled growth in population, inappropriate land development projects such as stock farming, irrigation, urbanization, industrialization, and unsustainable planning and utilization of natural resources are posing a rising threat to the ecosystem of major river basins across the globe. It is an astonishing fact to notice that the situation is worse even in countries like India, where rivers are treated as sacred goddess since time immemorial. River bodies are now receivers of mammoth quantities of hazardous contaminants discharged from industrial, agricultural and domestic sectors. On the other hand, excessive withdrawals and diversions of river water to satisfy the human greed through various multi-purpose projects, barrages, wasteful irrigation, industrial expansion, and inland navigation have vastly languished the natural environmental-flows and self-assimilative capacity of the river systems. The consequences of such negative impacts on the water body are indisputably perceivable in the contemporary society, which are reflected in the form of increasing water-borne diseases such as cholera, cancer, lungs and liver damage, brain hemorrhage etc., extinction of natural habitats and some beautiful species like Royal Bengal tiger and Ganges Dolphins , climatic changes, land infertility, over-dependence on technology even at the cost of disrupting natural environment, and poverty. newlineThere is no doubt that over the last three decades, experts, researchers and governmental bodies have been quite successful in creating an awareness amongst the humans about the acute necessity of understanding the dangers of consequences of such unkind, inconsiderate and hostile over-exploitation of rivers on present as well as future generations. However, a considerable effort remains to be endorsed to develop a single pointed focus on restoration of river bodies by channelizing the academic research, governmental policies and public participation into one single and efficient decision support.Item A Study on the Effect of Carbonation on Properties of Concrete(BITS, Pilani, 2017) Shaik, HussainItem Assessment of Potential of Marble Slurry As a Mineral Admixture in Concrete(BITS, Pilani, 2019) Singh, ManpreetItem Behaviour of Shallow Footings Resting on Waste Tire Chips Reinforced Sand and Copper Mining Wastes(BITS, Pilani, 2020) Gill, Gourav Deep SinghItem Interaction Curves for Design of Hollow Reinforced Concrete Columns(BITS Pilani, 1994-10-27) Kumar, RanjanItem Design and implementation of a generic methodology for scenario development with assessment over water resources(BITS, Pilani, 2019) Kumar, GauravItem Investigation Mapping and Treatment Techniques for Fluoride Nitrate and TDS in Groundwater of Shekhawati Region (Rajasthan India)(BITS, Pilani, 2017-08) Singh, Arun NihalItem Study of Structural Response and Failure Characteristics of Thin Walled Flanged FRP Beams(BITS, Pilani, 2018) Chawla, HimanshuItem Development and Usage of Ductile Composite Materials for Retrofitting and Strengthening of Masonry Structures(BITS, Pilani, 2018) PankajItem Proportioning of Self Compacting Concrete Mixes Based on Plastic Viscosity Approach Experimental and Numerical Investigations(BITS, Pilani, 2018) Kalyana, Sri Rama JItem Development of Integrated Environmental Pollution Index for Industrial Clusters(BITS, Pilani, 2016) Vidyarthi, Ajit KumarItem Study of Postbuckling Response Failure and Strength of Functionally Graded Composite Plates with Cutouts(BITS Pilani, 2021) Vummadisetti, SudhirItem Development of Data-Driven Decision Support Approaches Using Non-Destructive Testing for Enhancing Pavement Management Systems(BITS Pilani, 2020) Vyas, VidhiItem Sustainable Management of Groundwater Resources in the Western Arid Regions of Rajasthan India(BITS Pilani, 2020) Bhakar, PrashantItem Environmental quality assessment of a few selected stretches in a river basin using multi criteria approaches(BITS Pilani, 2015) Chakrabarti, SumantaThe contemporary problems of population explosion, rapid transformation of the newlineobjectives in economic development strategies irrational utilization of finite energy newlineresources and unprecedented instances of rapid urbanization are challenging the very newlineframe work of environmental quality and sustainability. The obvious consequences of newlinesuch unrestrained and uninhibited exploitation of the environmental resources have newlinereflected in a significant increase in the degradation of our immediate and surrounding newlineenvirons, as manifested in poverty, environmental pollution, proliferation of slumps and newlinesquatters, inadequate waste management and impure water supply, vehicular pollution, newlineincrease in traffic jams, road accidents etc. Though, human awareness has been newlineincreasing on the pivotal necessities of understanding and undertaking crucial changes in newlinethe perspective of environmental exploitation to suit our needs, a considerable effort still newlineremains to be endorsed to identify and establish holistic indices of environmental quality newlineand its immediate future remedial policy appropriate to regional preference and newlineacceptance. To this end, the present study involves a conscious effort to establish the newlinedesired indices of environmental quality through a robust analytical and perception newlinestudy endeavour thus help to establish a pro-active platform of decision making to newlineenvision a pragmatic and fruitful recourse to uphold the sanctity of our environment. newlineThis study has made an attempt to identify the major issues of the environmental quality newlinedemanding priority in the selected study areas, subsequent to which unique fuzzy newlinemultiple-attribute decision support platforms have been proposed for an integrated quality newlineassessment of the environmental attributes under study. The decision support system has newlinebeen developed by combining the principles of Multi-Attribute Decision Making newlineAnalysis and fuzzy set theory in order to reflect the spatial distribution characteristic of newlinethe environmental quality and to address the inherent uncertainty associateItem Experimental investigations for curling stress in self compacting concrete pavements(BITS Pilani, 2015) Gandage, Abhijeet SiddappaA highway pavement is a structure consisting of superimposed layers of processed materials newlineabove the natural soil sub-grade. In India, flexible pavements are preferred for road constructiondue to lower construction costs and speedy construction as compared to rigid pavements. newlineHowever, the maintenance costs of the rigid pavements are relatively lower as compared to the newlinemaintenance costs of flexible pavements. The rigid pavements are constructed by casting cement newlineconcrete slabs over dry lean concrete or granular sub-bases. The cement concrete pavements are newlinedesigned to withstand traffic loads and environmental loads during its service life. The newlineenvironmental factors that are considered in the concrete pavement analysis are temperature, newlinehumidity, precipitation and frost/heave. The stresses induced in the concrete pavements on newlineaccount of daily temperature variation are termed as curling stress. The curling stresses are as newlineimportant as axle loads in the concrete pavement analysis as they alone can trigger the failure of newlinethe cement concrete pavements. newlineThe rigid pavements are constructed with normally vibrated concrete. Self-compacting concrete newline(SCC) is preferred over normal concrete mainly due to improved mechanical properties and newlinespeed of construction. Due to environmental regulations and concerns, the use of natural river newlinesand in concrete manufacture is becoming impractical and obsolete. Nowadays crushed sand is newlinewidely used in concrete manufacturing process. Hence, the properties of SCC mix prepared with newlinenatural sand and crushed sand were tested in the present research. SCC is a concrete with high newlinebinder content, which poses a challenge from the point of view of sustainability. Thus, use of newlinepozzolanic materials like fly ash and its effect on the properties of SCC were also investigated. newlineIn the present study, 20% Class C fly ash dosage as a cement replacement material was obtainedthrough experimental trials. newlineThe thermal properties of concrete are influenced by the thermal properties of the matrix and newlineaggregate phase.Item Quantification of rural accessibility and development of a need based approach for Rural road network planning(BITS Pilani, 2015) Shalini, KAccessibility in rural areas may be characterized and quantified at distinctive levels regional and habitational. The regional accessibility gives a wide comprehensive view about overall accessibility in different nations, states, districts and blocks which help in positioning them according to their accessibility levels. Habitational level accessibility gives accessibility levels of each habitation to different sectors. They mirror the issues confronted by the villagers in getting to the essential or social needs. Quantifying accessibility at both the levels are valuable for planners and decision makers. In this study accessibility has been quantified at two different levels. newlineRural Access Index (RAI), one of the indicators developed by the International Development Association (IDA) has been utilized to find accessibility at regional level. The indices were also determined as per Pradhan Mantri Gram Sadak Yojana (PMGSY) definition of accessibility. This method has been used to find out the contribution of the construction of all-weather roads on improving accessibility in rural areas at regional level. As a case study, PMGSY roads viz., all-weather roads have been considered in this study. RAI has been determined with and without the presence of PMGSY roads as the difference will show the improvement in accessibility levels made due to these roads. Considering the fact that the accessibility would vary with the spatial position of the villages, case studies were conducted in five districts namely Alwar, Jhunjhunu, Tonk, Bikaner and Churu of Rajasthan, India, having different population densities. newlineThe outcome of this method is expected to help the policy makers in ranking the districts and blocks in terms of accessibility levels and accordingly allocate funds for the uniform development of the state. From the impact analysis using PMGSY definition, it has been observed that there is a notable improvement in accessibility in all the districts but was higher in densely populated districts.Item Development of cement concrete with non – biodegradable waste products and supplementary materials – an experimental investigation(BITS Pilani, 2014-04-10) Venu, MalagavelliItem Novel 3C Concepts in Isoparametric and Anisoparametric Finite Elements(BITS, Pilani, 2010) Muralikrishna, R
