Accurate reconstruction of the human brain in MRI-T1 images is valuable and important to clinical needs. In this paper, the morphology and snake techniques are proposed to reconstruct a human brain model. First step in our method is to preprocess the volumetric image to remove skull, muscle, fat, and other non-brain tissue. We use a method of 3-d region growing. It has the advantage over thresholding that the resulting objects will be spatially connected, since brain has the connected property. Second, we use clustering method, and than use them to produce an initial estimate of the cortical surface. Third, we propose a novel active contour algorithm to move the snake toward the cortex. Thus we can use the snake to segment the brain. We use a wavelet method to model the external force that significantly increases the capture range of a traditional snake. Afterwards, we render the volumetric image to display the brain from multiple views. Both simulated data and patient data have been use to test the proposed techniques. The proposed method combines various techniques of 3-D morphology, clustering, active contour, wavelet, and volume rendering to accurately, robustly, and automatically reconstruct brain from MRI-T1 images.

New Schottky structures (Ti/W/Cu, Ti/Co/Cu, Ti/Mo/Cu),with copper and refractory diffusion barrier metal, for GaAs Schottky diodes were evaluated. For the widely used Ti/Pt/Au Schottky diode, the thick overcoat gold layer was replaced with copper; Pi layer was replaced with the transition metals such as W, Co and Mo. The choice of the refractory metals was I based on their resistivity and the capability as the anti-diffusion barrier. The multi-layer metals were sputtered on the surface of n-GaAs. The Schottky metals were annealed at 15.0degreesC-300degreesC after deposition. Them ideality. factor and Schottky barrier height are 1.08/0.78eV, 1.07/0.71eV and 1.06/0.76eV for Ti/W/Cu, Ti/Co/Cu and Ti/Mo/Cu. structure respectively after annealing at 150degreesC for 2 minutes. The electrical properties of these contacts are, comparable with the typical Ti/Pt/Au Schottky diode which has an ideality factor close to 1.07. From the XkD results, the Ti/W/Cu and Ti/Mo/Cu Schottky structures are thermally stable after annealing up to 400degreesC for 30 minutes; Ti/Mo/Cu Schottky structure is. thermally stable up to 300degreesC annealing for 30min These results show that the new. Schottky. structure's have excellent electrical characteristics compare to the traditional Ti/Pt/Au structure and can be used as the Schottky metals for GaAs devices.

In the previous work, Lampson et al. proposed an IP lookup algorithm which performs binary search on prefixes (BSP) [1]. The algorithm is attractive, even for IPv6, because of its bounded worst-case memory requirement. To achieve fast forwarding, it may need to slow down the insertion speed. Although this can be justified, the routing-table reconstruction in BSP is too time-consuming to handle the frequent route updates. In this work, we propose a fast forwarding-table construction algorithm which can accomplish more than 4,000 route updates per second. Moreover, it is simple enough to fulfill the need of fast packet forwarding. With the enhanced multiway search tree, we further reduced the depth of the tree and eliminated the pointer storage; this reduces the forwarding table size and shortens the lookup time.

The Internet and World Wide Web represent an increasingly important channel for retail commerce as well as business transactions. However, there are almost 5 billion pages or sites on the Internet and WWW. There lacks an integrated mediator business agent which is around the internet to connect between suppliers and users. Therefore, an intelligent business broking agent between supply and demand is needed for using and sharing the information efficiently and effectively. In this paper we proposed a new business agent architecture. The Business Spy Agent (BSA) captures the supply and demand information from e-commence sites automatically. Supply and Demand Analysis Mechanism (SDAM) uses NLP technologies to extract product and trading information. Domain ontology is used to classify between supply and demand and to divide them into subsets. A benefit model is proposed to handle the pairing between sub-supply and sub-demand. And a divide-and-conquer algorithm is proposed to handle the whole matching between supply and demand. In the negotiation process, the architecture uses NLP and template to produce negotiation text to handle negotiation through mail. Finally, Hidden Business Mining Mechanism (HBMM) adopts data mining technology to achieve hidden business mining. The architecture covers the four process of buying behavior including support and need identification, Product brokering, Merchant brokering, Negotiation.
