Superamphiphobic surfaces, exhibiting high contact angles and low contact angle hysteresis to both water and low surface tension liquids, have attracted a great deal of attention in recent years due to the importance in many practical applications. In this
Combinatorial testing has been shown to be a very effective testing strategy. After a failure is detected, the next task is to identify the actual fault that causes the failure. In this paper, we present an approach to fault localization that leverages the

In this paper we present a method to combine measurement techniques that reduce uncertainties and improve measurement throughput. The approach has immediate utility when performing model-based optical critical dimension measurements. When modeling optical
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-39, Integrated Enterprise-Wide Risk Management: Organization, Mission and Information System View. This publication was developed by the Joint Task Force Transformation
Global resource degradation, climate change, and environmental pollution are worsening due to increasing globalized industrialization. The manufacturing industry has thus been put under pressure to cope with these problems while maintaining competiveness

Trace detection is a primary strategy for thwarting terrorism activities in the US and abroad. The development of effective reference materials and methods for this purpose relies on fundamental knowledge regarding the size, mass, morphologies, and
Representatives of the Nuclear Utilities Industry and the laboratory accreditation community met to discuss Nuclear Regulatory Commission (NRC) recognition of the use of accredited commercial calibration laboratories as suppliers of commercial grade
Finding shortest feasible paths in a weighted graph has numerous applications including admission and routing in communication networks. This paper discusses a game theoretic framework intended to incorporate a concept of path stability into the process of
A critical step in selecting the most appropriate repair strategy for a distressed concrete structure is to determine the corrosion status of reinforcing bars. Because of the complexity of the corrosion process, it is prudent to involve personnel who are
