Archives of Advanced Engineering Science, 2023 In this paper, the homing-phase guidance law is proposed against a stationary target in the planar engagement scenario. In this problem, two technical criteria that the guidance law must achieve are: first, zero terminal miss distance, and second ...

$\mathcal N=2$ Supersymmetry Deformations, Electromagnetic Duality and Dirac-Born-Infeld Actions [PDF]
, 2019 We study the general deformation of $\mathcal N=2$ supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the $SU(2)$ R-symmetry corresponding to the magnetic dual of the triplet of the Fayet-Iliopoulos (FI) parameters.

Opaque Branes in Warped Backgrounds [PDF]
, 2002 We examine localized kinetic terms for gauge fields which can propagate into compact, warped extra dimensions. We show that these terms can have a relevant impact on the values of the Kaluza-Klein (KK) gauge field masses, wave functions, and couplings to

Guidance law with impact time and impact angle constraints
Chinese Journal of Aeronautics, 2013 AbstractA novel closed-form guidance law with impact time and impact angle constraints is proposed for salvo attack of anti-ship missiles, which employs missile’s normal acceleration (not jerk) as the control command directly. Firstly, the impact time control problem is formulated as tracking the designated time-to-go (the difference between the ...

Direct Feedback Alignment with Sparse Connections for Local Learning [PDF]
, 2019 Recent advances in deep neural networks (DNNs) owe their success to training algorithms that use backpropagation and gradient-descent. Backpropagation, while highly effective on von Neumann architectures, becomes inefficient when scaling to large ...

Research on Cooperative Guidance Law of Multi-Missile Based on Trajectory Super-Real Time Simulation [PDF]
Hangkong bingqi, 2021 It is very difficult to conduct time cooperation guidance of multi-missile when the velocity of missile is uncontrollable. Based on the trajectory super real-time simulation method, which can gives out time-to-go exactly as well as future trajectory ...
