We study the model selection property of the Elastic Net. In the classical settings when p (the number of predictors) and q (the number of predictors with non-zero coefficients in the true linear model) are fixed, Yuan and Lin (2007) give a necessary and sufficient condition for the Elastic Net to consistently select the true model. They showed that it consistently selects the true model if and...

We analyze the photon-initiated processes for production of ${e}^{+}{e}^{\ensuremath{-}}$ pairs in proton-nucleus collisions at LHC energy, taking into account both elastic and proton dissociations low-mass region (LMR) intermediate-mass (IMR) as defined by ALICE collaboration. The calculations are performed within ${k}_{\mathrm{T}}$-factorization approach, including transverse momenta intermed...

Piezoelectric wafer active sensors (PWAS) at high temperature with reliable operation are desired for structural health monitoring. The PWAS may be generalized as an electromechanical system because of the incorporation of electromechanical coupling. The basic principle of SHM method by PWAS is to monitor variation in the electro-mechanical (E/M) impedance/ admittance signature. The operational...

in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...

This article offers a new insight to the achievable stiffness limitation of impedance control series elastic actuators (SEAs) by suggesting comparative analysis energy ports and passivity framework at port enhance maximum rendered SEAs. To this end, it is explored that SEAs have two different definitions assess system - spring load port; conservatisms for evaluation are investigated compared ut...

Successful wavelet estimation is an essential step for seismic methods like impedance inversion, analysis of amplitude variations with offset and full waveform inversion. Homomorphic deconvolution has long intrigued as a potentially elegant solution to the wavelet estimation problem. Yet a successful implementation has proven difficult. Associated disadvantages like phase unwrapping and restric...
