The Chebyshev or L∞ estimator minimizes the maximum absolute residual and is useful in situations where the error distribution has bounded support. In this paper, we derive the asymptotic distribution of this estimator in cases where the error distribution has bounded and unbounded support. We also consider the asymptotics of set-membership estimators such as the Chebyshev centre and maximum in...

Losing information when a storage device or data center fails can bring a company to its knees—or put it out of business altogether. Such catastrophic outcomes can readily be prevented with today’s storage technology, albeit with some difficulty: the design space of solutions is surprisingly large, the configuration choices are myriad, and the alternatives interact in complicated ways. Thus, so...

Every year, two million people become infected with the HIV virus in Africa, disproportionally affecting under 25 year olds and women. To address these challenges, governments and development partners have scaled up HIV behavior change campaigns (BCC) targeting youth. In many African countries, young women are twice as likely to be infected as young men, with transactional sex and gender-based ...

Controlled and efficient power consumption is a challenge faced daily by small, medium, and large data center (DC) administrators. Specialized and technical literature defines several guides, equipment, and mechanisms for this purpose. However, the combined application of these solutions is a complex task, which in several cases implies on high financial investment. In this context, we present ...

Shaping America’s Youth (SAY) took a model of civic engagement, the town hall meeting, applied it to a critical national health issue, and then went a step further by scientifically analyzing the results. Because of my 30-year experience with the civic-engagement field as a practitioner, a foundation program officer, and a director of an academic research center, I was invited by the SAY leader...

Traditional datacenters are designed as a collection of servers, each of which tightly couples the resources required for computing tasks. Recent industry trends suggest a paradigm shift to a disaggregated datacenter (DDC) architecture containing a pool of resources, each built as a standalone resource blade and interconnected using a network fabric. A key enabling (or blocking) factor for disa...
