    Imaging technologies such as optical coherence tomography (OCT), two-photon excitation fluorescence microscopy (TPEF), and second harmonic generation (SHG) microscopy require optical scanners to transversely scan a focused laser beam onto the tissue specimen being imaged. However, for in vivo early-cancer detection of internal organs the optical scanners must be integrated into slender endoscopes. The goal of this work is to develop millimeter-sized MEMS optical scanners packaged inside endoscopes to enable endoscopic biomedical imaging. This work reports MEMS micromirrors and microlens scanners fabricated using post-CMOS micromachining processes, which can provide large scan range...

    Recent years have seen a steady rise of a new class of data management systems called Data Stream Management Systems (DSMS). These systems manage rapid, high-volume data-streams with transient relations instead of static data with persistent relations. Data streams are common to applications such as network traffic and transaction monitoring systems, click-stream processors, industrial process control, and sensor networks. A DSMS operates on these continuous and time-varying data streams to facilitate on-the-fly query answering, and to support data acquisition, monitoring and analysis. In this dissertation, we present statistical stream mining solutions for effective on-line processi...
