We present circuits and techniques which allow the extraction of fine-grained timing information using a simple, scan-based, test-access port such as the JTAG/IEEE 1149 standard. We go on to show how these techniques can be combined with other simple circuits for post-fabrication timing control. These techniques open up opportunities to perform timing oriented tests through TAP control. Further...

Vision and audio can be used in a complementary way to efficiently create augmented reality tools. This paper describes how sound detection can be used to enhance the efficiency of a computer vision augmented reality tool such as the MagicBoard. A MagicBoard is an ordinary white board with which a user can handle both real and virtual information, allowing, e.g., for a copy&paste operation on a...

Abstract The flexible on-load transformer can be adapted to different application scenarios by adding power electronic converter structures through the use of existing transformers. In this paper, a regulator structure based on floating capacitor multi-level AC/AC is proposed, which compensate input voltage primary side in same direction or opposite direction, combine with tap-changer, and also...

task assignment problem (tap) involves assigning a number of tasks to a number of processors in distributed computing systems and its objective is to minimize the sum of the total execution and communication costs, subject to all of the resource constraints. tap is a combinatorial optimization problem and np-complete. this paper proposes a hybrid meta-heuristic algorithm for solving tap in a h...

conclusions open gastrostomy was successfully performed under subcostal tap block with small dose fentanyl supplementation. the subcostal tap block is considered a useful anesthetic choice in surgery for high risk patients. introduction many papers have reported that tap block provides effective postoperative analgesia, but the sole use of tap block for surgical anesthesia has been rarely repor...
