The concept of high-order motion compensation is introduced. It is argued that in hybrid video coding, motion-compensated prediction has to be viewed as a source coding problem with a delity criterion. Based on our considerations, various high-order motion compensation approaches are presented that achieve signi-cantly improved video coding results. The designed motion-compensated predictors ac...

conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...

The transient dynamics of a beam mounted on springer-damper support and equipped with a nonlinear energy sink (NES) is investigated under the effects of shock loads. The equations of motion are derived using the Hamilton’s principle leading to four hybrid ordinary and partial differential equations and descritized using the Galerkin method. An adaptive Newmark method is employed for accurate an...

Response to editorial regarding a novel surgical treatment option in which posterior dynamic stabilization is used to correct coronal plane tilt of a lumbar total disc replacement We recently described a novel surgical treatment option in which posterior dynamic stabilization (PDS) is used to correct coronal plane tilt of a lumbar total disc replacement (TDR). 1 Clinical and radiographic outcom...

From High-Level Tasks to Low-Level Motions: Motion Planning for High-Dimensional Nonlinear Hybrid Robotic Systems

The kinematics of dust particles during the early stage of mode-coupling induced melting of a two-dimensional plasma crystal is explored. It is found that the formation of the hybrid mode causes the particle vibrations to partially synchronize at the hybrid frequency. Phase- and frequency-locked hybrid particle motion in both vertical and horizontal directions (hybrid mode) is observed. The sys...

This paper presents a complete video codec which supports both block-based and mesh-based motion compensation modes. While the mesh-based modes are suitable for spatially continuous representation of in-plane rotations, zooms, and other motions that can be represented by parametric mappings; the block-based modes (especially overlapped block matching) perform better around motion boundaries. Th...

Probabilistic and deterministic planners are two major approximate-based frameworks for solving motion planning problems. Both approaches have their own advantages and disadvantages. In this work, we provide an investigation to the following question: Is there a planner that can take the advantages from both probabilistic and deterministic planners? Our strategy to achieve this goal is to use t...

This paper presents a motion description language (MDLp) for specifying and encoding autonomous puppetry plays in a manner that is faithful to the way puppetry choreography is currently formulated. In particular, MDLp is a formal language whose strings, when parsed by a dynamical system (the puppet) produces optimized, hybrid control laws corresponding to strings of motions, locations, and temp...
