Full-waveform inversion, a high-resolution seismic imaging method, is known to require sufficiently accurate initial models converge toward meaningful estimations of the subsurface mechanical properties. This limitation due nonconvexity least-squares distance with respect kinematic mismatch. We propose comparison five misfit functions promoted recently mitigate this issue: adaptive waveform ins...

Background Reducing rearfoot eversion is a commonly desired effect in clinical practice to prevent or treat musculoskeletal dysfunction. Interventions that pull the lower limb into external rotation may reduce rearfoot eversion. Objective This study investigated whether the use of external rotation elastic bands, of different levels of stiffness, will decrease rearfoot eversion during walking...

We apply kinematic and dynamic modeling to the 2015 Mw8.3 Illapel, Chile, earthquake constrained by continuous high-rate GPS strong motion data. Kinematic inversion elliptical patches allows us rapidly outline ruptured area with different time windows frequency ranges. The preferred solution indicates that main large patch in north is preceded a small one south close hypocenter shift no greater...

The rupture process and tectonic surroundings of the 2008 Wenchuan, China, earthquake are both complex in a way that might be related to the heterogeneous stress field of the Longmen Shan region. In this study, we construct dynamic models with heterogeneous initial stress to reproduce a kinematic inversion result by Wen et al. (2012) and investigate the physical mechanisms of the variable slip ...

OBJECTIVE To compare the differential effect of custom orthoses on the lower extremity mechanics of a forefoot and rearfoot strike pattern. DESIGN Fifteen subjects ran with both a forefoot and a rearfoot strike pattern with and without orthoses. Lower extremity kinematic and kinetic variables were compared between strike pattern and orthotic conditions. BACKGROUND Foot orthoses have been sh...

-A computer aided method has been proposed for detecting isomorphism among planar kinematic chains with sample joints using a new invariant called the arranged sequence of modified total distance ranks of all the links (ASMTDRL). This invariant takes into account the degrees of'links, and degrees-of-freedom and types of joints of the kinematic chain. Two computer aided methods have also been de...

We present a neural method that computes the inverse kinematics of any kind of robot manipulators, both redundant and non-redundant. Inverse kinematics solutions are obtained through the inversion of a neural network that has been previously trained to approximate the manipulator forward kinematics. The inversion provides difference vectors in the joint space from difference vectors in the work...

Recent studies of strong motion data consistently show that the risetime (duration of slip at particular locations on the fault) is significantly shorter than the overall rupture duration. The physical explanation for this observation and its implications have become central issues in earthquake source studies. Two classes of mechanisms have been proposed to explain short risetimes. One explana...

We analyze the behavior of redundant robots when the joint motion is generated by inverting task velocity commands through a kinematic control scheme. Depending on the chosen inversion scheme, the robot motion is subject to differential constraints that may or may not be integrable. Accordingly, we give a classification in terms of holonomic, partially nonholonomic, and completely nonholonomic ...
