ABSTRACT We propose in this letter an analytical method for realizing bandpass filters with N reflection zeros (RZs) but more than transmission (TZs) that are flexibly (symmetrically or asymmetrically) positioned outside the passband. The approach relies on development of asymmetric dual‐behavior resonators at lowpass domain, accommodating one zero (RZ) and two TZs. These DBRs then properly adopted into in‐line prototype, allowing them to be cascaded conventional via constant...
Abstract In this study, the on‐chip generation of microwave signals are proposed for controlling nearby quantum bits in a low‐temperature environment, utilizing superconducting logical and RF components. To achieve enhanced amplitude microwave, single flux (SFQ) pulse pairs employed, which can have either same or reversal polarity, serving as basic elements generator. The SFQ then combined wave‐shaped by using combining filter, finally outputs desired with narrow line‐width. signal...
Abstract Bird strike prevention is an important part of airport safety production management. For bird identification technology in business, this paper summarizes various research results using artificial intelligence for recognition, and analyses the pros cons different types application actual control business. Also, current prospected.
Video-based bus passenger collection is considered to have a greater potential for counting passengers, but the difficulty lies in how solve problem of accurately tracking and determining direction moving target under complex state motion. The traditional detection algorithm, like frame subtraction edge detection, very difficult deal with situation immediate multi-objective. Based on image preprocessing, an algorithm about intelligent video multi-target traffic statistics designed aiming at...
This paper studies a class of gradient-descent heuristic algorithms for the bi-level demand adjustment problem (DAP), which seeks to adjust origin-destination (OD) matrices based on observed link flows in congested transportation networks. We first present general solution framework DAP and then examine further develop its two building blocks, namely, gradient approximation stepsize calculation. presents four calculation methods, methods are newly developed. Similarities differences between...
