Maneuver Models Tracking Filter Of Nonballistic Near Space Targets, Qin Lei, Junlong Li

Journal of System Simulation

Abstract: Because hypersonic vehicles in the near space often adopt the way of nonballistic maneuver flight with characteristics of high speed and lift-to-drag ratio, flying in atmosphere for a long time, whose motion trajectories are sometimes characterized by “hopping”, their flight altitudes, flight velocities and flight accelerations change. Targets maneuver are characterized by long period maneuver, which has brought great difficulties with ground defense system for maneuvering target localization and tracking. Traditional filtering algorithms obviously cannot give accurate target state estimation, tracking performance has declined. The overview of tracking filter ways was given, introducing four typical nonballistic maneuver models of …

Restoring Humanity To Those Dying Below: An Inquiry Concerning The Ethics Of Autonomous Weapons Systems, Juliette A. Pouchol

Dartmouth College Undergraduate Theses

Today, autonomous weapons systems promise to make war more precise and effective while removing the human component from the battlefield. With the improvement of deep learning and computer vision, machines will soon be able to navigate and search through contested environments, discriminate between targets, and engage appropriately. The memoirs of drone pilots point to the evolving psychological impact of killing caused by the increase in the amount of empathy and emotional connectedness that drone pilots develop towards their target during the intimate surveillance period.

Honors Program Contracts

Adversaries launch cyberattacks or cyber-exploits with contrasting intentions and desired outcomes. A cyberattack is a malicious attempt by a state, third party, or individual to disrupt a computer’s network; whereas, a cyber-exploit is an action that uncovers and steals “confidential” information from a computer’s data. 1 Within this research paper, the main adversary of such cyberattacks and/or exploits will be the nation-state. The victims of these cyberattacks will range from multinational corporations, such as Sony, to nuclear programs in Iran. This essay will focus on four motivations behind such cyberattacks: (1) private sector hacking (the theft of intellectual property) (2) …
