Observations of spontaneous kicking patterns in infants have presented valuable insights into their development. At times, these kicking patterns can detect potential developmental delays in at-risk infants to help support diagnosis and intervention. However, the prevalence of developmental disabilities has increased and a protocol for early diagnosis is still not widely available outside of direct...
Monitoring the spontaneous kicking patterns of infants can give insight into their development. A computer vision based method for estimating the pose of an infant's leg from range images is presented in this paper. After some manual inputs for initialization, the range data associated with the infant is extracted. The method uses Robust Point Set Registration (RPSR) to fit an articulated model to...
As to digital arrays, amplitude-phase inconsistency between channels has a great influence on the performance of the adaptive antenna. With regard to the imbalance of chirp signal caused by the mismatch of channels, this paper studies the characteristics of the chirp signal and adaptive filter, and proposes a method based on the LMS adaptive filtering algorithm to eliminate the amplitude-phase inconsistency...
estimating the regolith depth from brightness temperature (TB) measured by a multi-channel radiometer at 3GHz, 7.8GHz, 19.35GHz and 37GHz. To establish the accurate microwave radiation or scattering model of lunar surface, firstly we need to determine an accurate model of dielectric constant of lunar regolith. However, until now there is no model of dielectric constant suitable for microwave band...
A fully dynamic flash ADC is attractive for its low-power and low-input capacitance natures. It has minimal static current consumption, and its power and area costs diminish as process advances. However, the comparators thresholds, which are set by the built-in offsets, are sensitive to supply and temperature drifts. This threshold variation may result in up to ±20% ADC gain error with ENOB degradation...
A novel transition between conductor-backed coplanar waveguide (CBCPW) and substrate integrated waveguide (SIW) is presented for microwave and millimeter-wave integrated circuit design. The proposed integrated transition that can provide simultaneous field and impedance matching, exhibits outstanding low-loss performances over an ultra-wideband range (entire Ka-band in our case). In this work, a generalized...
