The major public health burden of cervical cancer and its associated lesions warrants the development of effective preventive measures and successful therapies. Cervical cancer is the second most common female cancer worldwide, with approximately 493,000 diagnoses and 270,000 deaths annually. The disease can be detected early by cervical cytology in the pre-malignant phase, in the form of high-grade...
A current-fed DC-DC converter with zero-current switching (ZCS) is presented in this paper. The front stage, which is a DC-DC buck converter, is used to regulate the output voltage by utilizing pulse-width modulation. The rear stage, which is a push-pull DC-DC converter by using the current-fed technique, is used to transfer energy from low voltage side to high voltage side for high voltage applications...
This study uses two low-cost and compact CMOS cameras to construct an asynchronous binocular system and proposes an effective real-time front-vehicle detection algorithm with the binocular system. The proposed vehicle detection algorithm uses the edge information to detect the region of each front vehicle, and then computes the disparities of the front vehicles by an adaptive search method. According...
Summary form only given. LT-GaAs, with subpicosecond photoexcited carrier lifetime is currently the premier material for fabricating ultrafast optoelectronic devices. An alternate arsenic-rich material arsenic-ion-implanted (As/sup +/ ion-implanted) GaAs has recently emerged. The structural and electrical characteristics of GaAs:As/sup +/ and low temperature (LT) GaAs are very similar. Photoexcited...
