Given the large number of medical specialties in the AMEDD, determining the appropriate number of hires and promotions for each medical specialty is a complex task. Griffin and Bastian developed an objective force model to project the number of hires, promotions, and personnel inventory for each medical specialty across the AMEDD to support a 30-year life cycle.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EPh.D. student \u003Cstrong\u003ESimon Mak\u003C\/strong\u003E and Professor \u003Cstrong\u003ERoshan Vengazhiyil\u003C\/strong\u003E won the Quality, Statistics, and Reliability section\u0026rsquo;s Best Student Paper Competition for \u0026ldquo;Support Points.\u0026rdquo; In this paper, Mak and Vengazhiyil discuss how support points are a new way to compact a probability distribution into optimal sampling points.

It removes the computation shackles and leaves it on us to keep as much long-term patterns as required for the data analysis. SGT is a paradigm shift in sequence mining\u0026mdash;flat computation and higher accuracy.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EJosh Reed\u003C\/strong\u003E, an alumnus of the ISyE Ph.D. program (2007), was awarded the Erlang Prize of the Applied Probability Society of INFORMS. The prize was awarded for his many outstanding contributions to the analysis of stochastic systems, but most notably for his resolution of a long-standing conjecture regarding the scaling of a fundamental model which arises in the study of queues. In particular, Reed showed that under very general assumptions, the number waiting in queue scales like the square root of the number of servers for a family of stochastic models which arises frequently in the study of service systems such as large-scale call centers. This answered a long-standing conjecture of one of the leaders in the field, Ward Whitt, who (along with Shlomo Halfin) proved in 1981 that this scaling is correct for the special case of exponentially distributed service times.\u0026nbsp; To prove this result, Reed developed many new tools in the theory of stochastic processes, especially so-called measure valued processes, which are required to deal with the complex mathematics of general service time distributions in many-server systems. He now joins the ranks of many associated with Georgia Tech who have won this prize in the past, including Ton Dieker, Bert Zwart, and Jim Dai.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ETuo Zhao\u003C\/strong\u003E, who will join ISyE as an assistant professor in January 2017, received the SAS Data Mining Best Paper Award for \u0026ldquo;Calibrated Multivariate Regression with Application to Neural Semantic Basis Discovery.\u0026rdquo; Zhao\u0026rsquo;s paper proposes a novel sparse learning method for adaptively estimating high-dimensional multivariate regression models in a neural semantic basis discovery experiment.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003E\u003Cstrong\u003ESecond Place\u003C\/strong\u003E\u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWilliam W.
