Programmatic/Technical Accomplishment

Landmark International Standardization for 3DModel-based Engineering

EL On Dec. 1, 2014, the International Organization for Standardization released "STEP AP 242"; more formally, the international standard, 10303-242, Industrial automation systems and integration—Product data representation and exchange—Part 242: Application protocol: Managed model-based 3D-engineering. For more than five years from concept to international standard, EL provided technical leadership and facilitated the verification and validation of the specification with software implementers and stakeholders. The intent of STEP AP 242 is to support a manufacturing enterprise with a range of standardized three dimensional information models that flow through a long and wide digital thread that makes the manufacturing systems in the enterprise "smart." International Standard AP 242 will serve as an enabler of 3D model-based engineering, using computable models both within a factory and across a manufacturer's supply network.

EL Joins Data Mining Group

NIST is a new member of the Data Mining Group(DMG). DMG is an independent, vendor-led consortium that develops data mining standards such as the Predictive Model Markup Language (PMML). PMML is the leading standard for statistical and data mining models and supported by over 20 vendors and organizations. With PMML, it is easy to develop a model on one system using one application and deploy the model to another system using another application. PMML has reached a significant stage of maturity and has obtained broad industry support, allowing users to develop predictive solutions within one application and use another to execute them. Converting data into insights for manufacturing decision making for sustainability, agility, and asset utilization require advanced predictive modeling. The EL's Smart Manufacturing Programs will be working closely with DMG and its members to expand the PMML standard for smart manufacturing applications. The potential standards that will interface with PMML include STEP-NC (process information), MT Connect(machine data), and AMPL (optimization language).

EL Participates in Meeting to Align Green Building Standards and Codes

The American Institute of Architects; American Society of Heating, Refrigerating and Air-Conditioning Engineers(ASHRAE); the International Code Council (ICC); the Illuminating Engineering Society (IES); and the U.S. Green Building Council (USGBC) recently agreed to develop a coordinated set of requirements for high performance buildings in order to better coordinate existing green building standards, codes, and rating systems. The kickoff meeting for this effort was held at ASHRAE headquarters in December 2014 to discuss how to implement this agreement. EL's Andrew Persily participated in his role as the chair of ASHRAE Standard 189.1-Standard for the Design of High-Performance Green Buildings. Standard 189.1, co-sponsored by ASHRAE, IES and USGBC, is the only industry consensus standard covering sustainable design in commercial, institutional and high-rise residential buildings. The scope of the standard includes site sustainability, water-use efficiency, energy efficiency, indoor environmental quality, and the building's impact on the atmosphere, materials, and resources.

It is currently a compliance option under ICC's International Green Construction Code (IgCC), and the recent agreement is intended to achieve better coordination between Standard 189.1 and the IgCC. In combination with the USGBC LEED rating system, the new approach to standards and code development discussed at this meeting is intended to result in a single green code that supports the building community's effort to achieve high-performance, sustainable buildings.

EL Hosts Workshop on Wildland-Urban Interface Fires

Fire in the wildland-urban interface (WUI) is a rapidly growing national problem. A national workshop on this topic was hosted by EL on Jan. 6, 2015, at NIST Gaithersburg in an effort to exchange information on some of the latest WUI fire research, to see how the NIST research program's pieces fit together, and to help develop new ideas on how best to address this national problem. The stakeholder community was invited to participate, and the workshop was broadcast over the Internet. About 30 people participated online and another30 attended in person, some travelling from various corners of the USA. This was a valuable workshop, with the discussion informing ongoing strategic planning and research efforts. A webcast of the all-day seminar has been archived and will be available online for playback for one year:

EL and ITL Researchers Receive 2014Government Computer News Award for Information Technology Excellence

NIST researchers from EL and ITL received the 2014Government Computer News (GCN) Award for Information Technology Excellence for speeding development and delivery of secure, battlefield-handy—and sometimes life-saving—smartphone apps to U.S. troops in Afghanistan. The NIST team of engineers and computer scientists was funded by the Defense Advanced Research Projects Agency (DARPA) under its Transformative Apps (TransApps) program. NIST contributed two brands of expertise—cybersecurity and software performance evaluation—and organized outside collaborators to accomplish DARPA's objective: "Develop a diverse array of militarily-relevant software applications using an innovative new development and acquisition process. "Now concluding, the four-year NIST effort included distilling soldiers' needs into app requirements, evaluating app performance, and designing a unique smartphone security architecture. This effort is among 10 (out of 170nominated) GCN-recognized public-sector projects "showing the power of mobile technology to transform the government IT enterprise. "During 2010, its first year, the partnership delivered a batch of secure smartphones and an initial set of soldier-defined apps to an Army brigade in Afghanistan. By 2013, about 4,000 mobile devices (modified commercial smartphones and tablets) were deployed in Afghanistan. The capability now features about 60apps—from map displays to a calculator for estimating blast distances to language games—and offers regular upgrades. The NIST team included Craig Schlenoff, Anthony Downs, Lisa Fronczek, and Brian Weiss from the EL,and Brian Antonishek, Tom Karygiannis, Steve Quirolgico, Brian Schulte, Angelos Stavrou, and Jeff Voas from ITL.

EL Authors Win Outstanding Paper Award at42nd North American Manufacturing Research Conference

Vis Madhavan, Brandon Lane, and Eric Whitenton from the EL Intelligent Systems Division, and Gary Lipczynski from Boeing Research and Technology in Huntington Beach, Fla., received the "Outstanding Paper Award" for their collaborative research on machining of composites as presented at the 42nd North American Manufacturing Research Conference in Detroit, Mich. Their paper was titled "Fiber Orientation Angle (FOA)Effects in Machining of Unidirectional CFRP Laminated Composites." Research goals were to observe, measure, and qualify chip and particulate flow at varying cutting conditions and fiber orientation angles while machining carbon fiber reinforced plastic (CFRP) disks. High-speed video synchronized with tool force measurements showed a range of interesting and unique chip formation mechanisms and work piece surface features. Tool measurements after machining also showed distinct wear patterns that depended on the CFRP layer thickness, and could be related to observations in the tool forces and video. In late 2013, Boeing approached NIST for collaboration in use of NIST's unique experimental facilities, developed for use in metal cutting research, to test machining of CFRP work pieces for validation of their physics-based machining models. CFRP work pieces and cutting tools were provided by Boeing. Experiments were planned and carried out jointly by NIST and Boeing. The Outstanding Paper Award was presented to Madhavan and Lane in attendance at the awards banquet held at the University of Michigan Jack Roth Stadium Club. The conference paper was selected and preapproved for publication in the Journal of Manufacturing Processes. This work was also highlighted in the July issue of Manufacturing Engineering magazine in its "Top-Flight Research Papers" section.
