Miniaturization of Broadband Stub Bandpass Filters Using Bridged-T Coils
IEEE Access, 2018 In this paper, broadband stub bandpass filters (BPFs) with very compact circuit sizes are proposed. Specifically, the circuit size of the conventional broadband stub BPF is largely reduced by replacing all transmission line sections with bridged-T coils.

Journal of Adolescence, EarlyView.ABSTRACT Introduction Resting heart rate (HR) measures reflect autonomic processes that could predict health risk behavior (HRB) in emerging adulthood when risky behavior is prominent. However, prior studies and extant theories are inconsistent, such that the relationships between HR measures and HRB could be positive or negative in direction.

Time Encoding Sampling of Bandpass Signals
, 2023 This paper investigates the problem of sampling and reconstructing bandpass signals using time encoding machine(TEM). It is shown that the sampling in principle is equivalent to periodic non-uniform sampling (PNS).

Inertial‐Based LQG Control: A New Look at Inverted‐Pendulum Stabilization
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Linear‐quadratic Gaussian (LQG) control is a well‐established method for optimal control through state estimation, particularly in stabilizing an inverted pendulum on a cart. In standard laboratory setups, sensor redundancy enables direct measurement of configuration variables using displacement sensors and rotary encoders. However, in outdoor

An Adaptive Contourlet HMM–PCNN Model of Sparse Representation for Image Denoising
IEEE Access, 2019 In this paper, we propose a novel model of sparse representation for image denoising that we call an adaptive contourlet hidden Markov model (HMM)-pulse-coupled neural network (PCNN).
