With the improvement of security requirements of individuals, businesses and countries, the identity authentication system based on face recognition technology is applied widely. The identity methods based on single theory, due to a variety of factors, have their own inherent limitations. In order to improve the efficiency and accuracy of face recognition, based on fusion of wavelet packet sub-images,...
In the human-robot interactions, it is an important research on the artificial intelligence that robots catch the human's attention information. This process has a significant impact on robot intelligence. In this paper, a system for extracting human's attention-information from interaction has been designed. On the basis of face detection and eye-area location, an algorithm, combined with ant colony...
To meet the requirements of power management ICs such as PWM controller and APFC, a 90dB error amplifier with a unity frequency of above 10MHz was proposed and realized. The supply voltage of the amplifier was between 12V and 18V. And its layout design was also discussed. The highlights in the amplifier architecture lay in its special BCD technology especially the use of bipolar transistors. Besides,...
Summary Antigen-presenting capability and expression of HLA-II antigens on peripheral blood monocytes were analyzed by isotope incorporation technique and indirect immunofluorescence assay with monoclonal antibodies Tü22, Tü 36 and anti-Leu-M2 in patients with acute and chronic myeloid leukemias (AML, CML). All patients (17 AML and 13 CML) demonstrated impaired antigen-presenting capability of monocytes...
