To address the demands of more computing power, vendors and researchers had been focusing on increasing the clock rate and including more components in a chip, but these technologies had also led to high energy consumption and overheating problems. When energy saving is considered, the Dynamic Power Management (DPM) technique can change the operating mode of some components in a system. When Non-Volatile...
Gestures contain enough information to distinguish a person from another. This ‘biometric’ feature is the basis of the Kinect-enabled system described in this paper, which is designed to identify a given person through a short chain of in-air gestures (2–3 ones). The user-dependent (trainable) system relies on a traditional Dynamic Time Warping classification algorithm. This core algorithm enhances...
The global optimal Web service selection based on quality of service (QoS) in cloud environment has become a research focus when there are lots of the same or similar services. In this environment, it is possible that many service users request the same or similar services at the same time, which will result in users' unsatisfied requirement and services' load imbalance. The existing service selection...
Although many methods of refining initialization have appeared, the sensitivity of K-Means to initial centers is still an obstacle in applications. In this paper, we investigate a new class of clustering algorithm, K-Alpha Means (KAM), which is insensitive to the initial centers. With K-Harmonic Means as a special case, KAM dynamically weights data points during iteratively updating centers, which...
