In this report the authors present a unified framework for carrying out safety calculations for the automated highway problem and obtain sufficient conditions for a set of continuous controllers to be safe and use these conditions to design a discrete scheme that switches between them....

Using a two-period model in which income is earned in the first period and saving can be invested in a risky asset, the authors explore the implications of the wealth tax and the consumption tax approaches for both the government and the wage earner. Settings under which decisions are made...

We study the role of crime and money in elections and politics in the context of several recent far reaching judgments of the Supreme Court and the Central Information Commission. Based on publicly available data of over 62,800 candidates who contested National and State Assembly elections from...

Civil society in Independent India has perhaps never been as active as it is today, except in the years before and during the emergency. We explore the role it has played in strengthening and deepening democracy. We focus largely on the work done on introducing transparency, and on raising voter...

Indian software service providers are in an enviable position due to unprecedented market growth, overseas shortage of manpower, and access to high quality, low cost manpower within the country. We describe two alternate models for future growth of top Indian firms: manpower based growth (MBG)...

We discuss the hypothesis that, in addition to the known critical point in water (below which two fluid phases — a lower-density gas and a higher-density liquid — coexist), there exists a “second” critical point at low temperatures (below which two liquid phases — a higher-density...

Traffic data is used to estimate current traffic conditions so that travelers and agencies can make better decisions about how to use and manage the transportation network. This research explores the fusion of probe data (vehicle speed and direction) with loop data (density, speed, and count) in...

According to the duality theory of traffic flow any well-posed kinematic wave (KW) and/or variational theory (VT) problem can be solved with the same methods either on the time-space plane or the time vs vehicle number plane. To achieve this symmetry, the model parameters and the boundary data...
