Broyles Special Activities and Innovation Operations Evaluation Group Copyright © 2017 CNA Abstract The military is on the cusp of a major technological revolution, in which warfare is conducted by unmanned and increasingly autonomous weapon systems. However, unlike the last “sea change,” during the Cold War, when advanced technologies were developed primarily by the Department of Defense (DoD), the key technology enablers today are being developed mostly in the commercial world. This study looks at the state-of-the-art of AI, machine-learning, and robot technologies, and their potential future military implications for autonomous (and semi-autonomous) weapon systems. While no one can predict how AI will evolve or predict its impact on the development of military autonomous systems, it is possible to anticipate many of the conceptual, technical, and operational challenges that DoD will face as it increasingly turns to AI-based technologies.

  • Advancing Federal Capacities for the Early Detection of and Rapid Response to Invasive Species Through Technology Innovation
    As an output of NISC Secretariat contract number D16PX00293, this manuscript fulfills action item 5.1.6 of the 2016–2018 NISC Management Plan. Contact Jason Kirkey, NISC Secretariat Director of Communications, if questions arise: [email protected]. Advancing federal capacities for the early detection of and rapid response to invasive species through technology innovation Authors Barbara Martinez, Alex Dehgan, Brad Zamft, David Baisch, Colin McCormick, Anthony J. Giordano, Rebecca Aicher, Shah Selbe, Cassie Hoffman Abstract Invasive species early detection and rapid response (EDRR) actions could integrate technologies, innovation, and other outside expertise into invasive species management. From early detection by forecasting the next invasion and improved surveillance through automation, to tools to improve rapid response, the next generation of management tools for a national EDRR program could integrate advances in technologies including the small size and ubiquity of sensors, satellites, drones, and bundles of sensors (like smartphones); advances in synthetic, molecular, and micro-biology; improved algorithms for artificial intelligence, machine vision and machine learning; and open innovation and citizen science. This paper reviews current and emerging technologies that the federal government and resource managers could utilize as part of a national EDRR program, and makes a number of recommendations for integrating technological solutions and innovation into the overall Federal Government response.

The McGraw-Hill of a division © Glencoe/McGraw-Hill, Copyright A big problem in launching an object into space is overcoming the force of Earth’s gravity. This is done with rockets. A rocket is a vehicle designed to propel itself by ejecting exhaust gas from one end. Fuel burned inside the rocket builds up pressure. Exhaust gases ejected from the end of a rocket push it forward. Rocket engines do not draw in oxygen from the surrounding air to burn their fuel, like jet engines.
