Despite their importance, there is limited evidence on how institutions can be strengthened. Evaluating the effects of specific reforms is complicated by the lack of exogenous variation in institutions, the difficulty of measuring institutional performance, and the temptation to ‘‘cherry pick’’ estimates from among the large number of indicators required to(More)
—We present a novel feedback protocol for wireless broadcast networks that utilize linear network coding. We consider transmission of packets from one source to many receivers over a single-hop broadcast erasure channel. Our method utilizes a predictive model to request feedback only when the probability that all receivers have completed decoding is(More)
—We introduce a novel feedback protocol, called SMART, for wireless broadcast networks that use linear network coding. We consider transmission of packets from a single source to many receivers over a single-hop broadcast erasure channel with heterogeneous links. We propose a predictive model to minimize feedback as well as extraneous data transmissions by(More)

As the fuel price is the 2nd largest costs, in airline industry, it has become a real challenge recently to be decreased. While there are many factors contributing to this, Load & Balance plays an important role in the scene. TRIMA our recently-patented software can uniquely improve the Center of Gravity Management and increase the fuel efficiency(More)

Professor Médard's group works extensively on various areas at the intersection of information theory and networking, in collaboration with other faculty at RLE, as well as at CSAIL, Professor Médard has ongoing research programs and collaborations with Orange/France Telecom, Alcatel/Lucent and Technicolor. Network coding provides cost benefits in a variety(More)
We develop and implement a novel, mobile phone-based information clearinghouse, and experimentally evaluate its ability to overcome information asymmetries and improve public service delivery to farmers in Punjab, Pakistan. Like many crowdsourcing websites, our clear-inghouse collects and disseminates ratings—here, on the success of government veterinarians(More)
