Integrated Urban Sanitation Decision Support Tool

This report is a prelude to the development of a Proof-of-Concept (PoC) decision support tool that will aid cities in providing cost-effective, inclusive and sustainable sanitation options for all with a particular emphasis on the urban poor This is proposed to be achieved through an integrated assessment framework of alternative sanitation technologiesA PoC decision support tool is planned to be developed, with an aim to facilitate an integrated approach to the sanitation investment planning process for ULB in India The PoC tool is envisioned to provide stakeholders the information and kno

The Pugh Controlled Convergence Method: Model-based evaluation and implications for design theory

This paper evaluates the Pugh Controlled Convergence method and its relationship to recent developments in design theory. Computer executable models are proposed simulating a team of people involved in iterated cycles of evaluation, ideation, and investigation.

Electrochemical Properties and First-Principle Analysis of Na x [M y Mn1-y ]O2 (M = Fe, Ni) Cathode

Sodium-ion batteries are the commercially and environmentally viable next-generation candidates for automobiles. Structural and electrochemical aspects are greater concerns towards the development of a stable cathode material. Selecting transition metals and their composition greatly influences charge order, superstructures, and different voltage plateaus. This, in turn, influences transport properties and cyclic performance. This article aims to study the electrochemical performance, diffusivity, and structural stability of Na x [M y Mn1−y ]O2 (M = Fe, Ni) as cathode.

Correlation Between Central Receiver Size and Solar Field Using Flat Heliostats

In Central Receiver Systems (CRSs), thousands of heliostats track the sunrays and reflect beam radiation on to a receiver surface. The size of the reflected image and the extent of reflection from the heliostats are one of the important criteria that need to be taken into account while designing a receiver, since spillage losses may vary from 2 to 16% of the total losses. The present study aims to determine the size of an external cylindrical receiver, such that the rays reflected from all the heliostats in the field are intercepted. 

24 x 7 Power for all : Strategies for Karnataka

This study was commissioned by Karnataka Electricity Regulatory Commission (KERC) to identify key implementable strategies for the state of Karnataka for achieving the objectives of 24x7 Power for All The study describes the power supply scenario in the State including estimates for future energy demand The status of 24x7 power supply is analysed along the dimensions of access (electrification), adequacy (per capita consumption), affordability (cost of supply), availability (duration of supply), and reliability Future plans for generation capacity are analysed to determine the range of fore

Transition Metal Oxides as Cathodes for Li-ion battery: Structure, stability and substitution effects

First–principles DFT simulations are computationally demanding but are reasonably accurate in predicting properties of battery cathode materials. Properties relevant to selection of cathode
material include electrochemical potential, structural stability, energy/power density and cycle life etc. Computational screening of materials speeds up the process of material discovery by
saving on costs of experiments and time. In addition, it helps in developing correlation between properties and structural and chemical aspects. Here we analyze some of these aspects for the

A Sustainable Development Framework for India's Climate Policy: An Interim Report

As a large developing country, India’s challenge is to meet its development aspirations in a carbon-constrained world This study, undertaken by the Centre for Study of Science Technology and Policy (CSTEP) uses Sustainable Development (SD) as the overarching framework and aims at equitable access to energy, clean air and water, food, health and livelihoods and economic growth The study connects elements of SD in an integrated bottom-up approach to understand the implications for economy, energy trajectories, emissions and costs
