Large-scale applications of Internet of things (IoT), which require considerable computing tasks and storage resources, are increasingly deployed in cloud environments. Compared with the traditional computing model, characteristics of the cloud such as pay-as-you-go, unlimited expansion, and dynamic acquisition represent different conveniences for these applications using the IoT architecture. One...
The aim of this study was to investigate the pathological classifications, clinical features, and natural history of pediatric cardiac tumors to provide a basis for the selection of an appropriate therapeutic method. The medical records of in- or outpatients with cardiac tumors at four hospitals were classified to analyze various types of tumor growth locations, clinical manifestations, surgical indications,...
A thorough research on the high-accuracy estimation for the electrical harmonic parameters by using the Interpolated FFT algorithm was conducted. The window type and width are the main factors influencing the analysis precision. Like Bartlett, Hann, and Hamming windows, Bartlett-Hann window has a main lobe at the origin and asymptotically decaying side lobes on both sides. It is a linear combination...
A new cognitive mobile communication system (CCMCS) is proposed in this paper, which can utilize the unlicensed frequency sufficiently, protect the investment of networks existed and support its evolution. Through the effective application of variable-band OFDM and multiband OFDM, the system can connect several narrow bands into a wideband, and support high speed data transmit. Synchronization to...
