1 Motivation The compliant walking models are often used for reproducing characteristic gait dynamics [1]. However, since they require the touchdown angles to be chosen independently, there is a limited explanation for the foot placement selection in relation to the state of the body. In this study, it is hypothesized that the foot placement is indicated by progression of the center of pressure...

In this paper we explore, from an algorithmic point of view, the extent to which the facial angles and combinatorial structure of a convex polyhedron determine the polyhedron—in particular the edge lengths and dihedral angles of the polyhedron. Cauchy’s rigidity theorem of 1813 states that the dihedral angles are uniquely determined. Finding them is a significant algorithmic problem which we ex...

Phase error compensation within motion compensation techniques requires range cell migration corrected SAR data. The main contribution of this paper is providing a non-approximated range cell migration correction (RCMC) for processing highly squinted SAR data. Embedded in the conventional Omega-K processing, the approach consists of two coordinate transformations carried out in the 2D frequency...

Face recognition using image-set or video sequence as input tends to be more robust since image-set or video sequence provides much more information than single snapshot about the variation in the appearance of the target subject. Usually the distribution of such image-set approximately resides in a low dimensional linear subspace and the distance between image-set pairs can be defined based on...

In recent years, space-borne synthetic aperture radar (SAR) polarimetry has become a valuable tool for sea ice type retrieval. L-band SAR proven to be sensitive toward deformed and is complementary compared with operationally used C-band classification during the early advanced melt seasons. Here, we employ an artificial neural network (ANN)-based algorithm on comprehensive data set of ALOS-2 P...

Surface electromyographic (sEMG) activity of the biceps muscle was recorded from 13 subjects. Data was recorded while subjects performed dynamic contraction until fatigue and the signals were segmented into two parts (Non-Fatigue and Fatigue). An evolutionary algorithm was used to determine the elbow angles that best separate (using Davies-Bouldin Index, DBI) both Non-Fatigue and Fatigue segmen...

Studies of angular and time distributions and CP-violating observables in Bs → J/ψφ decays yield a space of parameters which can be considerably reduced if relative strong phases among different amplitudes are specified. We show that the relations between Bs → J/ψφ and B → J/ψK amplitudes given by flavor symmetry [actually U(3) rather than SU(3)] are likely to be quite reliable, and hence the u...

as a biometric trait has the ability to be recognized in remote monitoring. In this paper, a method based on joint distribution of motion angles is proposed for gait recognition. The new feature of the motion angles of lower limbs are defined and extracted from either 2D video database or 3D motion capture database, and the corresponding angles of right leg and left leg are joined together to w...

We show that any simple planar n-gon can be meshed in linear time by O(n) quadrilaterals with all new angles bounded between 60 and 120 degrees. 1991 Mathematics Subject Classification. Primary: 30C62 Secondary:
