  • U.S. Army Corps of Engineers preliminary results show no areas of concern

    The U.S. Army Corps of Engineers St. Louis District completed sampling for radioactive materials at the Jana Elementary School in Florissant, Missouri, this week as part of the Formerly Utilized Sites Remedial Action Program. Preliminary results show no presence of radioactive material above the expected range of background levels (the level of radioactivity Mother Nature already provides).
  • Corps Announces Pause in Drawdown of Some Lakes Due to Drought Conditions

    HUNTINGTON, W.Va. - The Huntington District of the U.S. Army Corps of Engineers announces a pause in the normal drawdown at Alum Creek, Deer Creek, Paint Creek, East Lynn, Beech Fork, Grayson, North Fork of Pound, John W. Flannagan, Fishtrap, Dewey, and Yatesville Lakes as we evaluate the impacts of the drought/abnormally dry conditions in the area.
  • Network Development and Autonomous Vehicles: A Smart Transportation Testbed at Fort Carson

    Abstract: In this work, a smart transportation testbed was utilized at Fort Carson to demonstrate three use cases for the primary purpose to plan, develop, demonstrate, and employ autonomous vehicle technologies at military installations and within the surrounding communities to evaluate commercially available Connected and Automated Vehicles and the potential to reduce base operating costs, improve safety and quality of life for military service members and their families, and deliver services more efficiently and effectively. To meet this purpose, an automated vehicle shuttle, an unmanned aerial system, and a wireless network were used and tested during the project. Results for the automated shuttle indicated that de-spite the quantity of data generated by operations, the contractors may not be ready to share information in a readily usable format. Additionally, successful use by the public is predicated on both knowing their mobility patterns and staff members promoting trust in the technology to prospective riders. Results for the unmanned aerial system showed successful identification of foreign object debris and runway cracks at the airfield. The wireless network is now operational and is used for additional work which utilizes the installed traffic cameras.

  • A 𝘬-Means Analysis of the Voltage Response of a Soil-Based Microbial Fuel Cell to an Injected Military-Relevant Compound (Urea)

    Abstract: Biotechnology offers new ways to use biological processes as environmental sensors. For example, in soil microbial fuel cells (MFCs), soil electro-genic microorganisms are recruited to electrodes embedded in soil and produce electricity (measured by voltage) through the breakdown of substrate. Because the voltage produced by the electrogenic microbes is a function of their environment, we hypothesize that the voltage may change in a characteristic manner given environmental disturbances, such as the contamination by exogenous material, in a way that can be modelled and serve as a diagnostic. In this study, we aimed to statistically analyze voltage from soil MFCs injected with urea as a proxy for gross contamination. Specifically, we used 𝘬-means clustering to discern between voltage output before and after the injection of urea. Our results showed that the 𝘬-means algorithm recognized 4–6 distinctive voltage regions, defining unique periods of the MFC voltage that clearly identify pre- and postinjection and other phases of the MFC lifecycle. This demonstrates that 𝘬-means can identify voltage patterns temporally, which could be further improve the sensing capabilities of MFCs by identifying specific regions of dissimilarity in voltage, indicating changes in the environment.
