Figure 11. The result comparison of the lossy line circuit by SPICE3e2 and the 4th order approximation with non-time-of-flight (nonTOF) Figure 12. The comparison of the lossy line circuit by SPICE3e2 and the 4th order approximation with time-of-flight (TOF). 11 flight can be accurately extracted for computing the propagation delay. The accuracy of(More)
— The linearization of RF power amplifiers (PA) can benefit from the availability of the generalized Volterra coefficients characterizing its non-linear response. In this work a large-signal network analyzer is used to acquire the amplitude and phase of the 3 rd intermodulation terms Y m3-and Y m3+ of an LDMOSFET PA. The frequency dependence and difference(More)
Feature extraction from images, which are typical of high dimensionality, is crucial to the recognition performance. To explore the discriminative information while depressing the intra-class variations due to variable illumination and view conditions, we propose a factor analysis framework for separate “content” from “style,” identifying a familiar face(More)
Previous study and our laboratory have reported that short-wavelength (blue and green) light and combination stimulate broiler growth. However, short-wavelength stimuli could have negative effects on poultry husbandry workers. The present study was conducted to evaluate the effects of human-friendly yellow LED light, which is acceptable to humans and close(More)
