Three-phase partitioning (TPP), which is a simple, efficient, and green bioseparation technique, was used to extract and separate polysaccharides from Corbicula fluminea (CFPS). The optimal parameters with a high yield of 9.32% were as follows: mass fraction of (NH4)2SO4, 20.0% (w/v); amount of t-butanol, 9.8mL; temperature, 35.3°C; extraction time, 30min; and pH 6.0. The purified CFPS after TPP consisted...
Image annotation is a hard multi-label learning problem which aims at automatically tagging each input image with relevant keywords reflecting its semantic concepts. Recently, several late fusion methods were proposed to improve the accuracy of image annotation. But these late fusion methods need normalization of confidence score vectors of independent models corresponding to distinct representations...
In this paper, we aim to optimize the secrecy rate of the cellular user (CU) in a single cell where the Device-to-Device (D2D) communication shares the uplink resource with CU. The interference link from CU to the D2D receiver can be considered as the eavesdropping link in the sense that the D2D receiver may try to decode the cellular user's message. The proposed scheme aims to optimize the achievable...
Knowledge service is the integration of knowledge and services. Introducing the concept of “people-oriented” in pervasive computing to knowledge service, this paper constructs a kind of pervasive knowledge service model by means of multidisciplinary research achievements such as intelligence computing, system science, ecology, system science, knowledge science and service science, especially generalized...
The steel grounding grid buried in earth will corrode and become hidden danger to the safety of power system. It is important to examine the state of grounding. Particle swarm optimization (PSO) is a population-based, self-adaptive search optimization technique. This paper used combination of rotating and encouraging each location and incentives, many measurement method, established a new non-linear...
