—XML keyword search is a popular topic in research field, and the Smallest Lowest Common Ancestor (SLCA) concept is fundamental for XML keyword search algorithms. With the rapid growth of XML data in internet, we are confronted with big data issues, it's becoming a new research direction for managing massive XML data now. Conventional centralized data… (More)
Most existing works investigate consensus with noise following a certain distribution, e.g., Gaussian distribution, with fixed expectation and variance, which may not be satisfied in practical applications. This paper investigates the discrete system consensus under bounded noise, which is important and practical problem. We first provide necessary and… (More)
— This paper investigates the problem of discrete average consensus in the presence of bounded noise. Different from many existing works which mainly deal with noise with zero mean and bounded covariance, we consider the noise with bounded absolute value which is more practical in many applications. We first derive the necessary condition for the… (More)
This paper demonstrates a 180W packaged AlGaN/GaN HEMT targeted for S-band application, operating at 48V drain bias voltage. Under WCDMA (with DPD) test, the average power and drain efficiency are 35W and 33.3%. After 1000 hours HTRB test, no electrical failure of the device is observed.
The internet enables the rapid and easy creation, storage, and transfer of knowledge; however, services that transfer geographic knowledge and facilitate the public understanding of geographic knowledge are still underdeveloped to date. Existing online maps (or atlases) can support limited types of geographic knowledge. In this study, we propose a framework… (More)
