We consider a two-stage mixed integer stochastic optimization problem and show that a static robust solution is a good approximation to the fully adaptable two-stage solution for the stochastic problem under fairly general assumptions on the uncertainty set and the probability distribution. In particular, we show that if the right-hand side of the constraints is uncertain and belongs to a symme...

In this paper, we consider a two-cell interfering two-user multiple-input multiple-output multiple access channel (MIMO-MAC) with limited feedback. We first investigate the multiplexing gain of such channel when users have perfect channel state information at transmitter (CSIT) by exploiting an interference alignment scheme. In addition, we propose a feedback framework for the interference alig...

The use of virtualization technologies to increase the capacity and utilization of laboratory resources is widely used in classroom environments using several workstation based virtualization products. These virtual networks are often “air gapped” to prevent the inadvertent release of malware. This implementation however requires users to be in the classroom. A novel extension on this concept i...

Genomic alignments of sequenced cellular messenger RNA contain gapped alignments which are interpreted as consequence of intron removal. The resulting gap-sites, genomic locations of alignment gaps, are landmarks representing potential splice-sites. As alignment algorithms report gap-sites with a considerable false discovery rate, validations are required. We describe two quality scores, gap qu...

The Air Force is pursuing several efficiency initiatives designed to reduce support function costs. One such initiative is an effort to reduce the flow days of items being repaired in the Air Force’s organic depots. Many end items are affected by awaiting parts (AWP) delays, which increase total flow days. The first step in reducing AWP delays is to identify which piece parts are causing the de...

In the production function approach, an accurate output gap assessment requires a careful evaluation of the total factor productivity (TFP) cycle. We build a common cycle model that links TFP to capacity utilization and we show that, in almost all of the preenlargement EU countries, using information about capacity utilization reduces both the total estimation error and the revisions in real-ti...

| Substantial interest has developed in recent years in building computer systems that support cooperative work among groups without the need for physical proximity. This paper examines some of the diicult data management issues in designing systems for computer-supported cooperative work (CSCW). Speciically, we consider an example CSCW system to support large-scale team science over the Intern...
