Some multiplicity results for solutions of an impulsive boundary value problem are obtained under the condition of non-well-ordered upper and lower solutions. The main ideas of this paper are to associate a Leray-Schauder degree with the lower or upper solution.
The representation of human perception has become one of the most active research topics in image retrieval. This paper proposes a novel search result clustering based relevance feedback mechanism for image retrieval, in which the value of image co-occurrence is used for mining the association of images and then the tolerance rough class is adapt to… (More)
When the portable electronic devices work, the powers always change in large range. To ensure the normal operation of electronic equipments, we design a new low-power low-dropout regulator (LDO). The chip is fabricated on the CSMC 0.5µm CMOS technology. The Line Regulation is 0.08%. The PSRR is 44.34dB. The current is 9µA on no-load. It has… (More)
