The goal of this work is to provide a system which can aid in monitoring crowded urban environments, which often contain tight groups of people. In this report, we consider the problem of counting the number of people in the scene and also tracking them reliably. We propose a novel method for detecting and estimating the count of people in groups, dense or otherwise, as well as tracking them. U...

A 2+1-dimensional anisentropic magnetogasdynamic system with a polytropic gas law is shown to admit an integrable elliptic vortex reduction when γ = 2 to a nonlinear dynamical subsystem with underlying integrable Hamiltonian–Ermakov structure. Exact solutions of the magnetogasdynamic system are thereby obtained which describe a rotating elliptic plasma cylinder. The semi-axes of the elliptical ...

When a human grasps a cylindrical object, feedback on the orientation of the cylinder with respect to the axes of the digits is crucial for successful manipulation of the object. We measured the ability of humans to discriminate the orientations of cylinders passively contacting the fingerpad. For a cylinder of curvature of 521 m-1 (radius, 1.92 mm) subjects were able to discriminate, at the 75...

Abstract The object of this paper is the Saint-Venant torsion a solid elliptical cylinder made orthotropic homogeneous piezoelectric material. We find shape cross section which does not warp under applied torque. sizes section, has maximum value torsional rigidity for given cross-sectional area, are also determined.

By the method of numerical simulation, behavior deformation field both separated and related model fractal structures a cylindrical type was investigated. It is shown, that for considered structures, essentially depends on choice stochastic processes (realized during iterations) states qubit in perpendicular plane to axis cylinder. shown structure complex circular (elliptical) cylinder initial ...

Shear-driven flow between a rotating cylinder and stationary elliptical enclosure is studied in this paper. Two-dimensional time-dependent Navier–Stokes equations are solved using meshless method, where interpolations done with polyharmonic spline radial basis functions. The fluid analyzed for various aspect ratios of the ellipse eccentric placements inner cylinder. Contour plots vorticity stre...

Aerodynamic sound generation at low Mach numbers around complex stationary and moving bodies is computed directly with an immersed-boundary method-based hybrid approach. The complex flow field is solved by the immersed-boundary incompressible Navier-Stokes flow solver and the sound generation and propagation are computed by the linearized perturbed compressible equations with a high-order immer...
