Quality of Service (QoS) characterizes the non-functional aspects of Web service, which is the key factor for satisfying service users and has to be carefully considered in service oriented architecture. There has been a lot of works on QoS description and service selection by QoS information. However, two issues have not been substantially explored in QoS(More)
Anaphora resolution plays an important role in nature language processing. According to features of Chinese personal pronoun, we present an approach which adopts Conditional Random Fields to do anaphora resolution of personal pronoun in Chinese texts. The method takes into account all kinds of anaphoric features and those effects among each other. The(More)
The study of quantum neural networks (QNN) may give us unprecedented possibilities in creating new systems for information processing. We describe a model for quantum neuron (QN) and discuss the quantum learning rule. It is demonstrated that this single quantum neuron is able to perform the XOR function unrealizable with a single classical neuron and has(More)
Pedestrian detection technology which is based on vision is one of the core technologies in the intelligent transportation system. This paper focuses on the image and video in traffic system. The image and video are normalized and are extracted of histograms of oriented gradients (HOG) by using the linear support vector machine (SVM) to construct efficient(More)
The vision is the only way that people receives image information. Retinex is the theory and method of image enhancement that is based on experiments and analysis of vision. Retinex enhances the image by processing reflection R and incident light L from the image S to obtain better vision quality. It is described that the image appears to reflect or(More)
BACKGROUND Combined central diabetes insipidus and cerebral salt wasting syndrome after traumatic brain injury (TBI) is rare, is characterized by massive polyuria leading to severe water and electrolyte disturbances, and usually is associated with very high mortality mainly as a result of delayed diagnosis and improper management. METHODS We(More)
Glioma stem cells (GSCs) have been proven to play key roles in tumorigenesis, metastasis and recurrence. Although dihydroartemisinin (DHA), a derivative of the antimalaria drug artemisinin, has been shown to have anti-cancer activity, it is still unclear whether DHA affects GSCs. This study investigated the effects of DHA on the growth and apoptosis of(More)
