    摘要: Clustering algorithms such as k-means clustering algorithm are used in applications that process entities with spatial and/or temporal characteristics, for example, media objects representing audio, video, or graphical data. Feature vectors representing characteristics of the entities are partitioned using clustering methods that produce results sensitive to an initial set of cluster seeds. The set of initial cluster seeds is generated using principal component analysis of either the complete feature vector set or a subset thereof. The feature vector set is divided into a desired number of initial clusters and a seed determined from each initial cluster.

    摘要: A unified fuel processing reactor for a solid oxide fuel cell can reform hydrocarbon-based fuel into hydrogen-rich gas, remove a sulfur component, and convert non-converted fuel and a low carbon (C2˜C5) hydrocarbon compound into hydrogen and methane in a single reactor. The reactor comprises a primary-reformer which reforms a hydrocarbon-base fuel and generates hydrogen-rich reformed gas, a desulfurizer which removes a sulfur component from the reformed gas, and a post-reformer which selectively decomposes a low carbon (C2˜C5) hydrocarbon in the desulfurized reformed gas into hydrogen and methane. The primary-reformer, desulfurizer and post-reformer are in the unified reactor and isolated, except for a fluid passage, from each other by internal partition walls. The primary-reformer is disposed at a center portion of the reactor. The post-reformer and the desulfurizer are concentrically disposed outside of the primary-reformer.
