    The Environmental Imperative of Nuclear Disarmament

    Get PDF
    The world is threatened as never before by an insane buildup of nuclear weapons some five hundred times as strong in their explosive capacity as the latest estimate of all the chemical explosives that have ever been used throughout history. Leaders in major countries probably know the awful consequences of a nuclear war too well to start one, but the world has still to reckon with possible acts of aggression by other nations or flaring-up through technological failure, mechanical or other accident, malfunctioning or faulty feeding of computers, misinformation, neglect of machines or of constructional faults, terrorist or lunatic action, organized banditry, or the outcome of mere ‘acts of God'

    Strategic Missile Forces in Ukraine: Brief Survey of Past and Present Environmental Problems

    Get PDF
    Various environmental problems related to the former strategic missile forces located in Ukraine are outlined and analyzed. As the combat units and equipment have been disarmed and mostly utilized according to international agreements, various axiliary units, equipment, parts, stockpiles of the rocket fuel and oxidizer remained in Ukraine outside the agreements

    Trying to end the war on the world: the campaign to proscribe military ecocide

    Get PDF
    Military ecocide, the destruction of the natural environment in the course of fighting or preparing for war, has a long history and remains a regular feature of contemporary conflicts. Efforts to prohibit this in international law were initiated after the US’ notorious defoliation campaign in the Vietnam War in the 1960s and have advanced since then. Legal ambiguities and the defence of military necessity have limited the application of this body of law but the proscription of ecocide has, nonetheless, progressed and looks set to develop further. Normative change driven by scientists, environmentalists and legal experts has raised awareness of and stigmatised such practises to the extent that recourse to the worst excesses of ecocide now appears to have lessened and some recompense for past crimes has been made. Military activities, though, still inflict a heavy cost on the environment

    Two contemporary sociologists, Allan Bloom (The Closing of the American Mind) and Robert Bellah (Habits of the Heart: Individualism and Commitment in American Life), focus our attention to the growing problems in America brought about by our often individualistic and uncommitted values. Christian leadership struggles to find ways to bring Christians to a serious commitment to Christ

    Physics-constrained Hyperspectral Data Exploitation Across Diverse Atmospheric Scenarios

    Get PDF
    Hyperspectral target detection promises new operational advantages, with increasing instrument spectral resolution and robust material discrimination. Resolving surface materials requires a fast and accurate accounting of atmospheric effects to increase detection accuracy while minimizing false alarms. This dissertation investigates deep learning methods constrained by the processes governing radiative transfer to efficiently perform atmospheric compensation on data collected by long-wave infrared (LWIR) hyperspectral sensors. These compensation methods depend on generative modeling techniques and permutation invariant neural network architectures to predict LWIR spectral radiometric quantities. The compensation algorithms developed in this work were examined from the perspective of target detection performance using collected data. These deep learning-based compensation algorithms resulted in comparable detection performance to established methods while accelerating the image processing chain by 8X
