MESA-DER Specification (the Bluetooth of Energy Storage) Testing and Certification Program

Wheeles D., MESA Standards Alliance, US

The Modular Energy System Architecture (MESA) Standards Alliance is an industry association of electric utilities and technology suppliers. MESA’s mission is to accelerate the interoperability of distributed energy resources, in particular utility-scale energy storage systems, [...]

Accurate Pole Testing Can Increase Resilience of Power Supply Grid and Save Billions of Dollars at the Same Time

Deuar K., Kris Deuar & Associates, Inc., US

Resilience of power supply grid can be increased substantially by more accurate pole inspection and testing. Electric utilities are unnecessarily replacing or re-enforcing electrical poles that still have many years of useful life. Our proof [...]

Cost Effective Mitigation of Wildfire Risk Generated by Power Lines

Deuar K., Kris Deuar & Associates, Inc., US

The recently developed extremely accurate Micro- Stress Pole Testing (MSPT) technology can save a lot of money by elimination of costly replacements of poles which are prematurely rejected by presently used inaccurate pole inspection methods. [...]

Health Monitoring of Carbon/Carbon Composites Monitored by Ultrasonic TOF Technique

Won S., Korea Institute of Materials Science, KR

Carbon/carbon (C/C) composites reinforced with carbon nanotube are tested for their application to primary aircraft structures using ultrasonic testing. Ultrasonic testing is the most widely used and most powerful procedure for inspecting composites. Composites are [...]

Technologies for Deep Reductions in Military Operational Energy Use

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Mechanical Characterization of Metallic Nanowires by Combining Atomic Force Microscope (AFM) and Scanning Electron Microscope (SEM)

Celik E., Madenci E., The University of Arizona, US

Mechanical characterization of nanowires still poses challenges due to their small length scale. Existing nanowire mechanical characterization techniques in literature can be grouped as: 1) resonation of nanowires in an electron microscope, 2) mechanical characterization [...]

Assessment of the Impacts of Packaging, Long-Term Storage, and Transportation on the Military MEMS

Zunino III J.L., Skelton D.R., US Army ARDEC, US

The Army is transforming into a more lethal, lighter and agile force. Enabling technologies that support this transition must decrease in size while increasing in intelligence. Micro-electromechanical systems (MEMS) are one such technology that the [...]

Thermo-Mechanical Characterization and Integrity Checking of Packages and Movable-Structures

Szabo P., Perlaky G., Bognar Gy., Horvath Gy., Ress S., Poppe A., Rencz M., Courtois B., Budapest University of Technology and Economics, HU

The paper will present a variety of possibilities for the thermal characterization of different movable MEMS devices and packaging. It will discuss the major difficulties in these methodologies and the ways to overcome them. Comparison [...]

Adaption of the 3w-Method for Testing of MEMS

Raudzis C., Schatz F., Wharam D., Corporate Research, Robert Bosch GmbH, DE

Automated wafer level testing of MEMS requires methods to measure geometry and material related parameters by purely electrical means. The three omega method to measure the thermal conductivity seems to be appropriate for this task. [...]
