DOE/EFCOG Electrical Safety Workshop

Doug Coffland, Gary Dreifuerst, Bill DeHope, and Ed Chesney from Engineering attended the DOE/Energy Facility Contractor's Operating Group (EFCOG) Electrical Safety Workshop, which was held July 14–18 at the National Renewable Energy Laboratory (NREL) in Golden, CO. The workshop included tours of NREL followed by presentations on standards updates, DC arc flash information, personal protective equipment for arc flash, subsurface investigations, and electrical safety in the DOD. There were also breakout sessions dedicated to studying problems commonly encountered across DOE and recommending best-practice solutions to those problems. Doug Coffland led a breakout group discussing Authority Having Jurisdiction (AHJ) policy issues, while Gary Dreifuerst led a group addressing DC electrical hazards and controls

EFCOG is a self-directed group of contractors of DOE facilities whose purpose is to promote excellence in all aspects of operation and management in a safe, environmentally sound, secure, efficient, and cost-effective manner through the ongoing exchange of information and corresponding improvement initiatives. LLNL will host the next Electrical Safety Workshop, which is scheduled for July13–17, 2015.

LLNL Hosts 18th Annual Signal and Image Sciences Workshop

The 18th annual Signal and Image Science Workshop was held May 21, 2014, at the Livermore Valley Open Campus' High Performance Computing Innovation Center. A signature event of the Engineering Directorate's Center for Advanced Signal and Image Sciences (CASIS), the annual gathering serves as a showcase for R&D in signal and image sciences at Lawrence Livermore and Sandia national laboratories. Approximately 100 attendees visited this year's workshop to hear presentations and view posters, with topics that included signal and image processing, pattern analysis and machine learning, controls and communications, as well as application areas such as geophysics, astronomy, and the biosciences. The keynote speaker was Pietro Perona, an electrical engineering professor at Caltech and internationally recognized expert on computational vision. His address, "Visipedia – A Distributed Visual System Composed of Machines and People," explored the idea of a visual interface for Wikipedia that could answer visual queries and enable experts to contribute and organize visual knowledge.

This year's CASIS workshop was cosponsored by the Oakland/East Bay chapter of the Institute of Electrical and Electronics Engineers (IEEE) Signal Processing Society. You can learn more about CASIS by visiting https://casis.llnl.gov.


LLNL Hosts Argus User Group Technical Interchange Meeting

More than 25 security organization managers and technical representatives of the Argus User's Group (AUG) met April 29–30 at the Livermore Valley Open Campus to conduct business and exchange technical information related to the Argus security system. The Argus system—designed, engineered, and first installed at LLNL in 1988—consists of an extensive set of hardware and software components that are integrated to provide the physical security functionality required for protecting high-consequence Department of Energy (DOE) and Department of Defense (DOD) assets. Topics of discussion at the meeting included program management, budgets, technical updates from user sites, and the work strategy for the latest Argus system release, which offers Homeland Security Presidential Directive 12 (HSPD-12) compliance. The AUG includes members from LLNL, LANL, Y-12, Pantex, Idaho National Laboratory, Savannah River Site, and the Missile Defense Integration and Operations Center (MDIOC).


First Use of 3D Printing to Create Flexible, Stretchable Structures with Tailored Mechanical Properties

In an online article to appear in an upcoming issue of the journal Advanced Functional Materials, lead author Eric Duoss and other LLNL additive manufacturing (AM) researchers describe their results in employing direct ink writing (DIW) to create porous, elastomeric architectures with mechanical properties governed by the ordered arrangement of their submillimeter struts. According to the authors, this work represents the first time that 3D printing has been harnessed to pattern highly flexible and stretchable 3D periodic structures with tailored mechanical properties, including negative stiffness. The article describes how two layouts were patterned using DIW, one resembling a "simple cubic" (SC)-like structure and another akin to a "face-centered tetragonal" (FCT) configuration. These structures exhibited markedly distinct load response with directionally dependent behavior, including negative stiffness. These findings suggest the ability to independently tailor mechanical response in cellular solids via microarchitected design. According to the authors, such ordered materials may one day replace random foams in mechanical energy absorption applications. This work continues to build on foundational efforts enabled by the AM Laboratory Directed Research and Development Strategic Initiative.

Bond elected to LBNL Molecular Foundry User Executive Committee

Tiziana Bond was recently elected to serve a three-year term as a member of the Users Executive Committee for Lawrence Berkeley National Laboratory's Molecular Foundry. Members of the committee provide a channel of communication between Molecular Foundry users and management and represent users when the DOE solicits feedback from members of its National User Facilities. The Molecular Foundry is part of the DOE's National Nanotechnology Initiative, supporting broad nanoscience research efforts in both "hard" nanomaterials (nanocrystals, tubes and lithographically patterned structures) and "soft" nanomaterials (polymers, dendrimers, DNA, proteins and whole cells), as well as in the design, fabrication and study of multicomponent, complex, functional assemblies of such materials.
