SV-TAD: Native Sparse Convs for Efficient Temporal Action Detection
Ricardo Pizarro, Roberto Valle, José M. Buenaposada +2
To adapt billion-parameter Vision Transformers for long-video understanding, recent methods freeze the backbone and train lightweight convolutional modules. While effective for par…
Variable Dimension IMM and GPB2 Filters for Tracking in Multiple Model Systems
Roberto Pérez-Pérez, Ángel F. García-Fernández
This paper presents mathematically principled filters for multiple-model systems with states of different dimensionality, specifically the variable-dimension interacting multiple m…
Stability of Droop-Controlled Low-Frequency Transmission Lines
Rafael Castillo-Sierra, Giri Venkataramanan, Dionisio Ramirez
Low-Frequency AC (LFAC) transmission systems employing power converters are being considered for a varity of applications. This work studies the small-signal stability of an LFAC t…
Equivalent DQ Sequence-Domain Model of Unbalanced Three-Phase Passive Elements for Power Converter Controllers
Air\án Franc\és, Luis Saz, Rafael Castillo +2
Equivalent dq0 models of three-phase passive impedances are widely used for the design of three-phase inverter and rectifier controllers in the synchronous frame. However, these eq…
Impact of perturbative tensor interactions on the spontaneous fission half-lives of superheavy nuclei
R. Rodriguez-Guzman, A. Rakhmankulov, L. M. Robledo +1
The standard microscopic description of fission, based on the mean-field Hartree-Fock-Bogoliubov approximation and a semi-classical description of tunneling through the fission bar…
An implicit locking-free B-spline Material Point Method for large strain geotechnical modelling
Mian Xie, Pedro Navas, Susana López-Querol
The Material Point Method (MPM) has drawn great attention in the numerical modelling of large deformation, geotechnical problems. The popularity of MPM is mainly because its formul…
