Software Product-lines (SPLs) are software architectures that use modular software components that can be reconfigured into different variants for different requirements sets. Feature modeling is a common method used to capture the configuration rules for an SPL architecture. A key challenge developers face when maintaining an SPL is determining how to select a set of architectural features for...

This study integrates association rules analysis, a methodology for selecting potential interactions, with Poisson regression modeling. Though typically ignored in conventional Poisson regression, interactions are very common in practice. However, selecting a Poisson regression model when many main effects and interactions are involved is problematic. In this study, we develop a model selection...

To improve the scalability of the Web it is common practice to apply caching and replication techniques. Numerous strategies for placing and maintaining multiple copies of Web documents at several sites have been proposed. These approaches essentially apply a global strategy by which a single family of protocols is used to choose replication sites and keep copies mutually consistent. We propose...

In this paper, we discuss the concept of the expected opportunity cost of a potentially incorrect selection as a measure of selection quality on a new selection procedure that is used to selecting the top m systems for large scale problems. This procedure is used the ordinal optimization method to reduce the size of the search space, and then it is used the idea of computing budget allocation O...

Stroke is a feared complication of atrial fibrillation and leads to substantial morbidity and mortality (1). Atrial fibrillation not only increases the risk for ischemic stroke by approximately 5-fold, but atrial fibrillation–related strokes result in more deaths and disability than strokes of other causes (2). Anticoagulant therapy with vitamin K antagonists, such as warfarin, effectively redu...

Incentives in Core-Selecting Auctions Paul Milgrom October 18, 2006 A “core-selecting auction mechanism” is a direct mechanism for a multi-item allocation problem that selects a core allocation with respect to the bidders’ reported values and the auctioneer’s exogenously given preferences. For every profile of others’ reports, a bidder has a best reply that is a truncation report. For every “bi...
