Planning commonly applied to automating Web Service composition involves two problems (i) overlooked user needs combined with services provided by the systems themselves and outside services providing a much more flexible service model, (ii) "Speeding up" and "facilitating" services by not recording information about service providers already having served users and about planning already processed. We propose merging internal and external services to meet user needs. Internal services include system functions designed to meet user needs. External services mean Web services provided by outside service providers. We plan to combine both types of services to create planning to meet user needs. We apply case-based reasoning to store planning and related information in a case base to make planning much faster when users have similar needs. Source

Here we present an interactive guidance and navigation system that assists user in acquiring pictures for image based 3D modeling. To reconstruct an object's 3D model, user follows our instruction to take a set of images for an object in different angles, we calculate their relative viewing positions and spare point cloud data using structure from motion technique. After we obtain sufficient number of images, we use Patch-based Multi-View Stereo (PMVS) [1] software to generate dense point cloud data. When displaying dense point cloud, we provide user an interface to eliminate those noise data points yielded from background construction or re-projection errors. Afterwards we reconstruct surface mesh as output. Our system provides informative message for failures while calculating camera poses and helps user how to resolve those problems. Furthermore, we assess the quality of camera poses reconstruction and generated point cloud to reveal the lack of angles for captured images and guide user to remedy those information. Source

Exploiting a charge sharing method enables a performance power management design for domino circuits. The domino circuits have both high performance and low power consumption. A test chip has been successfully validated using TSMC 0.13um CMOS technology. Reductions in dynamic power consumption of 68% and static power consumption of 15% are achieved. ©2011 IEEE. Source

The bit cell is a key component that determines the VDDminand power consumption of a sub-threshold static random access memory (SRAM). A new bit cell with a pnn-type latch structure is proposed. The analysis and measurement results indicate that the pnn bit cell outperforms the conventional bit cells in terms of VDDminand power reduction. © 2014 The Institution of Engineering and Technology.
