Using the Gini index to measure the inequality in infrastructure services provided within an urban region
In this article, we suggest the use of the Gini Index to measure the inequality in infrastructure services provided within an urban region. We develop a functional form for the Lorenz Curve, the basis of measurement of the Gini Index. The sparse nature of data available to measure the distribution of infrastructure services within an urban region results in a challenge in estimating the Lorenz Curve.
Developing GIS tools for planning, mitigation and preparedness for large scale emergencies and disasters
Emergency and disaster management involves four stages: Mitigation (Planning), Preparedness, Response and Relief. Concerned authorities at different levels (central, state, district, etc.) play different roles and have different responsibilities in each phase of emergency and disaster management. GIS-based tools have been shown to be useful in the response and recovery phases of an emergency. In this paper, we propose how GIS-based simulation tools can be used in the Mitigation and Preparedness phases of emergencies and disasters.
A simple explicit model approximating the relationship between speed and density of vehicular traffic on urban roads
With the increase in simulation of urban environments for the purpose of planning, modelling vehicular traffic has become important. While empirical evidence on traffic flow is relatively sparse, models representing the same are being increasingly used for planning urban roads and environments. In this paper, a simple explicit model is proposed to approximate the speed versus density of vehicular traffic flow.

Improved solar power yield: A silver lining in times of COVID-19
The novel coronavirus pandemic has brought the world to a standstill. It has created a lot of uncertainty for many businesses. The outbreak has affected the Indian solar industry, hampering manufacturing and project development. According to CRISIL, 3 GW-solar projects of ₹160 billion are likely to get affected due to delays. This is a matter of concern for Indian project developers. But, amid this gloom, there is a silver lining. There is a lot to discuss about how India has achieved new records in solar power generation.
How to Handle Locust Swarms
Swarms of locusts are currently on the rampage in Maharashtra, Uttar Pradesh and Punjab, after leaving a trail of destroyed crops in Rajasthan, Gujarat, Madhya Pradesh and Haryana. These are no ordinary hoppers in that they become dangerous when they enter the gregarious phase, by forming swarms that can travel up to 150 km per day and eat as much as about 10 elephants in a day. When millions of locusts descend on a crop, they destroy everything, devastating the agricultural supply chain and livelihoods of farmers.
Planning for Physical Distancing May Be Challenging, but It Could Solve India's Housing Woes
By now, it is evident that India’s current housing conditions make it challenging to practice lockdown and self-quarantining effectively. For starters, our high population density and low open space per capita in urban areas make outdoor social distancing practically impossible.
Lockdown and the power equation
The advent of the novel coronavirus (COVID-19) pandemic had forced India to resort to a lockdown. To contain the spread of COVID-19, nationwide lockdown had been announced in phases since 24 March. This has adversely affected the power sector, hitting the demand and collection, and hence, the financial health of distribution companies (DISCOMs).

Water-reduction potential of air-cooled condensers in coal power plants in India and anticipated trade-offs
Wet cooling towers (WCT) are widely used to reject the unutilized heat in coal thermal power plants (TPPs). But this comes at the cost of excessive water consumption. Adoption of air-cooled condensers (ACC), also known as dry cooling systems, in all proposed Indian TPPs would reduce their water consumption by 26% in 2030. However, power producers are reluctant to install ACC due to technical and economic disadvantages such as high capital investment and land footprint.
