This paper develops an energy minimization algorithm to reconstruct the 3D motion of transplanted hearts of small animals (rats) from tagged magnetic resonance (MR) sequences. We describe the heart by a layered aggregate of thin oriented elastic fibers. We use the orientation of myo-cardial fibers to develop a local dense motion of the heart. This dense(More)
In this paper, an adaptive control method for target-enclosing strategies is considered. The proposed enclosing control strategy achieves enclosing configurations based on virtual structures. We assume that there exist an uncertainty in the information exchange topology between an agent and all of its neighbors on the network. We regard that the uncertainty(More)
This paper examines the problem of link position tracking control for robot manipulators with input toque uncertainty. It is assumed that the input torque uncertainty can be regarded as dead-zone effects at each link of manipu-lator and all the system parameters for dead-zone model and robot are unknown. The proposed method ensures that the unknown(More)
In Information-centric Networking (ICN), users can obtain contents from caches in ICN routers. However, how to use caches efficiently is one of challenges. One existing scheme to obtain caches uses a caching algorithm reducing cache overlaps among routers, and users can obtain caches by referring to records that routers have about caches. However, this(More)
This paper considers a formation control for leader and follower type multi robot systems. An alternative error function is given to achieve relative state deviation between followers. Also, a simple formation control strategy of multi robot systems is given. We can easily apply our method for the actual systems, because our proposed method does not contain(More)
