The National Academy of Engineering recently identified 14 grand challenges for engineering in the 21st century (www.engineeringchallenges. org). We believe that the continuing advances in ubiquitous sensing, processing, and computing provide the potential to tackle two of these 14 grand challenges: specifically, enhancing virtual reality and advancing(More)
In this article, we focus on the applicability of parallel computing architectures to video processing applications. We demonstrate different optimization strategies in detail using the 3-D convolution problem as an example, and show how they affect performance on both many-core CPUs and symmetric multiprocessor CPUs. Applying these strategies to case(More)
This paper proposes a new 3D propagation algorithm for the depth image-based rendering problem with multiple color and range cameras at arbitrary positions. The proposed algorithm efficiently renders novel images at arbitrary virtual views by propagating all available depth information from range cameras to color cameras, and then all available depth and(More)
This paper proposes a new approach for depth image-based rendering (DIBR) with low resolution depth using the 3D propagation algorithm. Our novel depth edge enhancement method efficiently corrects and sharpens the depth edges in the propagated depth image using available high resolution color information. Experimental results show that only with 4% depth(More)
This paper reports on the design and fabrication of a z-axis tuning fork gyroscope which has a freestanding architecture. In order to improve the performance of the tuning fork gyroscope by eliminating the influence of the squeeze-film air damping, the driving and sensing parts of the gyroscope were designed to oscillate in-plane. Furthermore, by removing(More)
BACKGROUND Kinesin spindle protein (KSP) plays a critical role in mitosis. Inhibition of KSP function leads to cell cycle arrest at mitosis and ultimately to cell death. The aim of this study was to suppress KSP expression by specific small-interfering RNA (siRNA) in Hep3B cells and evaluate its anti-tumor activity. METHODS Three siRNA targeting KSP(More)
Gamma Ray Bursts (GRBs) are believed to be the most powerful explosions that have occurred in the Universe since the Big Bang and are a mystery to the scientific community. " Swift " , a NASA mission that includes international participation, was designed and built in preparation for a 2003 launch to help to determine the origin of Gamma Ray Bursts.(More)
