An Interview with Philip Piqueira, Global Standards Leader for GE’s Industrial Solutions Business

General Electric participates in standards development through its work on numerous committees and organizations. Philip Piqueira discusses why this business strategy and its continuance is crucial for GE.

From your perspective as the global standards leader for General Electric’s Industrial Solutions business, would you discus

Providing Statistical Confidence to Pass

Q. Lots are released based on comparing test results from a sample to lot acceptance procedure criteria. If a set of test results meets the lot acceptance procedure criterion, how can I be assured that another sample from the lot would also pass the criterion?

A: Companies use lot acceptance procedures to release a lot. Test results from a sample are evaluated against lot acceptance procedure criteria,

My standards education began in 1990 when I became the chairman of an ASTM International task group. I was the group leader of R&D for a medical device manufacturer, recognized the need for a specific industry standard and felt that taking a leadership role in developing this standard would be a good professional development activity. The standard was eventually approved and I continue to serve as a subcommittee chairman.

The main thermodynamic forces active in the near field of a nuclear fuel waste multiple barrier system during the unsaturated stage are the gradients of temperature, fluid pressure, and chemical potentials. The processes that have a direct impact on the transport mechanism of heat and moisture within the clay-based compacted buffer material are coupled. The major problems in describing coupled heat and moisture flow (CHMF) in unsaturated swelling clay barriers are the lack of experimental data a

Many interface and sand-to-sand direct shear tests have been performed with a constant normal stiffness to investigate the effects of interface roughness, normal stiffness, soil relative density, initial normal stress, and cyclic displacement amplitude on the soilinterface response. It is demonstrated that the patterns of behavior in these tests are similar to those observed in model pile tests and that the constant normal stiffness (CNS) condition is required to account for the effects of the v
