Abstract

The global and regional systems for managing water resources are thought to be significantly impacted by climate change. Due to the fact that poor nations are most impacted, it has grown to be a significant worldwide problem. Natural disasters like aridity, droughts, floods, cyclones, and severe rainfall are all likely to have an impact on humans. Water scarcity can be brought on by climate change in some countries through persistent droughts. The rising population will result in a greater demand for water. Cities are becoming more vulnerable to water-related problems as a result of increased urbanization, changing rainfall patterns, and industrialization. The supply and demand of water can be balanced through the implementation of sustainable practices. In the event of future climate change, rainwater harvesting systems offer an alternative source of water and specific adaptation strategies for coping with water scarcity. The adoption of rainwater harvesting systems is discussed in this article as a strategy for climate change.

Abstract

This paper aims to establish the effect of Green House Gases (GHGs) emissions on climate change. Greenhouse gas molecules formed due to anthropogenic activities absorb infrared radiations from the sun, and these molecules re-emit the radiations in all directions, causing temperature rise of the Earth's surface. Due to anthropogenic activities in the country, GHG emissions of GHGs are increasing. The motor vehicles running in the Indian cities with the fossil fuels like gasoline, diesel, etc., are emitting Carbon-di-oxide (CO2), Hydrocarbon (HCs), Nitrogen oxides (NOx) and water vapor as greenhouse gases in the form of vehicular exhausts. These emissions are responsible for deteriorating ambient air quality of the cities like Delhi, National Capital Region (NCR), Mumbai, Kolkata, Bangalore, Hyderabad, etc. This paper outlines the necessary technologies and practices to mitigate GHG emissions of GHGs. The paper also discusses some of the strategies for reducing emissions of GHGs to minimize the effect of global warming and climate change. The impacts of implementing energy efficiency and conservation measures, the role of renewable energy, and hydrogen blends in the vehicular fuel Compressed Natural Gas (CNG) are also described in this paper. The emission performance of a passenger car suitable for bi-fuel combustion with 18 Hydrogen Compressed Natural Gas (18HCNG) has been compared with neat CNG fuel. The economic analysis with these two vehicular fuels in respect of reducing CO2 and NOx being greenhouse gases, has also been discussed in this paper.

Abstract

The improvements in the regional precipitation characteristics over the land regions of globe from Coupled Model Intercomparison Project-3 (CMIP3) and Coupled Model Intercomparison Project-5 (CMIP5) model group are examined. This research employed 11 General Circulation Model (GCMs) from both generation of models and combined them from both Multi Model Averaging (MMA) and Bayesian Multi Model Averaging (BMA) to ascertain the upgradation in projections for both seasons. BMA method offer better alternative to MMA as higher weights are assigned to better performing models for more skillful regional projections. Our results elucidate the fact that both combinations of models and methods inform spatially similar non-uniform changes in projections of precipitation across these models. The models do not express much progress in mean simulations for both 20th and 21st century projections. Thus lower uncertainty for CMIP5 group than CMIP3 is observed. Therefore, the findings highlight that mere comparisons based on mean statistics alone may not be sufficient to understand their progress. However, advanced methods of analysis provide better insights in their model development.

Abstract

India is a developing nation and due to emerging new infrastructure in various sectors, the demand of electricity is always higher than generation. Smart Grid is an automated system which includes automation of existing electrical infrastructure into modern and controlled system with the help of IT control, Internet of Things (IoT) systems that enables real-time monitoring and control of bi-directional power flows and information flows from generation to consumption. Electricity demand is a major issue in India and with the help of these technologies the demand of electricity can be managed in reliable and economic mode. Consumers can monitor real-time energy consumption of their energy use, and this can be reflected in supply, demand and generation of energy. State utilities send their billing data to Electricity Regulatory Commission every year where billing data analysis is carried and new tariff of electricity is decided by the Regulatory Commission to all Consumers of Electricity in the State. Web based Geographical Information System (GIS) can help by mapping all electrical infrastructures on a digital map including their complete details and all consumers can be mapped. Web based GIS can help to state utilities as a tool for plan and manage their all assets by logging into the system from anywhere. Web based GIS can help to manage area wise Load Scheduling by integrating Road, Buildings, Lands, Transmission Stations, Transmission Lines, Generation Stations and consumer's detail. This system can help for Load Forecasting, Decision Making and Electricity Demand Management for State Utilities, Regulatory Body and Policy Makers towards making effective approach in Energy Conservation and Efficiency.

Abstract

Additive Manufacturing (AM) is an emerging technology, used to fabricate components in layer by layer fashions. It has several key merits such as part customization, ability to produce complicated shapes etc. that are not possible by traditional machining methods (Lathes, Shapers, Planner, Slotter, Milling etc.). The timeline of the scientific and technological developments survey reported that owing to the attractive properties and growing demand it will be used to fabricate full body origin in 2032. This paper aims to provide an overview of additive manufacturing methods, materials, merits and demerits, cost comparision, future scope, challenges and distinct industrial applications, so that this study helps upcoming researchers working in the field of additive manufacturing.
