In this paper we will report a novel CMP slurry chemistry which can provide tunable removal selectivity between various silicon-containing materials, such as SiGe, bare silicon, poly silicon or amorphous silicon against SiO2 and/or SiN. The slurry chemistry is a non-hydrogen peroxide based system containing a novel catalyst. By adjusting the amount of the catalyst, we can fine tune desirable removal...
In this paper, we propose the human recognition framework based on the biometric trait conveyed by a walking subject, where the viewing angles of gallery and probe may differ. To deal with this kind of intra-class variance, we propose to exploit the view transformation technology to transform the embedded vector of one viewing angle into another embedded vector of target viewing angle. Then, the metric...
In this paper, a scheme is proposed for solving segmentation problem when people engage in body contact in a video sequence. First, the body parts belonging to each interacting person are extracted using the deformable triangulation technique. The color blobs of each person are learned by Gaussian mixtures model on the fly before the person is interacting with another. Finally, those learned blob...
Five types of service flows are defined in the standard of IEEE 802.16. Each service flow has its own type of quality of service (QoS) requirement. Some scheduling algorithm is needed to satisfy the QoS requirement of each class. Traditional base station (BS) allocates bandwidth according to the request of user. However, the request may not equal to the real requirement in some situation. Thus, the...
Sketch-based algorithms are widely used in networking applications due to its many good attributes. We propose to use Graphics Processing Unit (GPU) as an accelerating engine to offload heavy sketch computations for network traffic change detection. Our experiment results show that GPU can conduct fast change detection with query operation up to 9 million distinct keys per second. It is capable of...
In this paper, we propose a simple but effective human identification method based on gait features using frame difference history image (FDHI). Before constructing the FDHI feature, a sequence-based silhouette normalization scheme and an alignment pre-processing step are applied. After that, a post-processing step is devised for getting more representative gait signatures for human identification...
In the IEEE 802.16 system, the bandwidth is allocated by the Downlink and Uplink scheduler. All Subscriber Stations know when they should send or receive from the DL_MAP and UP_MAP information. For most existing schedulers, the bandwidth is allocated with the maximum sustained rate. If the allocated bandwidth of one queue has reached the maximum sustained rate, there will be no more bandwidth for...
