— In this paper, we propose a frame rate up-conversion algorithm using the weighted-adaptive motion-compensated interpolation (WAMCI) that reduces the block artifacts due to the failure of motion estimation and block-based processing. The proposed method is based on the interpolation scheme by weighted sum of multiple motion-compensated interpolation (MCI)(More)
This paper describes Newton and quasi-Newton optimization algorithms for dynamics-based robot movement generation. The robots that we consider are modeled as rigid multibody systems containing multiple closed loops, active and passive joints, and redundant actuators and sensors. While one can, in principle, always derive in analytic form the equations of(More)
Recent research suggests the importance of controlling rotational dynamics of a humanoid robot in balance maintenance and gait. In this paper, we present a novel balance strategy that controls both linear and angular momentum of the robot. The controller's objective is defined in terms of the desired momenta, allowing intuitive control of the balancing(More)
—This paper considers the problem of geocasting in mobile ad hoc networks. Geocasting, a variation on the notion of multicasting, is a mechanism to deliver messages of interest to all nodes within a certain geographical target region. Although several geocasting protocols have already been proposed for mobile ad hoc networks, with the goal of achieving an(More)
The IEEE 802.16 mobile multi-hop relay (MMR) task group 'j' (TGj) has recently introduced the multi-hop relaying concept in the IEEE 802.16 WirelessMAN, wherein a newly introduced relay station (RS) is expected to increase the network performance. In this context, we consider the problem of path selection where several RSs might exist between the base(More)
The GacS/GacA two-component regulatory system activates the production of secondary metabolites including phenazines crucial for biological control activity in Pseudomonas chlororaphis 30-84. To better understand the role of the Gac system on phenazine regulation, transcriptomic analyses were conducted by comparing the wild-type strain to a gacA mutant.(More)
We introduce a comprehensive biomechanical model of the human upper body. Our model confronts the combined challenge of modeling and controlling more or less all of the relevant articular bones and muscles, as well as simulating the physics-based deformations of the soft tissues. Its dynamic skeleton comprises 68 bones with 147 jointed degrees of freedom,(More)
