Texture mapping, bumpmapping, and displacement maps are central instruments in computer graphics aiming to achieve photo-realistic renderings. In all these techniques, the mapping is typically oneto-one and a single surface location is assigned a single texture color, normal, or displacement. Other specialized techniques have also been developed for the rendering of supplementary surface detail...

Given a sparse set of feature matches, we want to compute an interpolated dense displacement map. The application may be stereo disparity computation, ow computation, or non-rigid medical registration. Also estimation of missing image data, may be phrased in this framework. Since the features often are very sparse, the interpolation model becomes crucial. We show that a maximum likelihood estim...

Large-displacement Lightweight Armor Randomly entangled fibers forming loosely bound nonwoven structures are evaluated for use in lightweight armor applications. These materials sacrifice volumetric efficiency in order to realize a reduction in mass versus traditional armor materials, while maintaining equivalent ballistic performance. The primary material characterized, polyester fiberfill, is...

Global internal displacement Worldwide, in 2012, a total of 28.8 million persons were displaced from their homes due to generalized violence and human rights violations, while remaining within the borders of their countries of origin, the highest figure ever recorded. Based on the United Nations report, Guiding Principles on Internal Displacement, the international humanitarian aid community us...

We recall briefly the displacement rank approach to the computations with structured matrices, which we trace back to the seminal paper by Kailath, Kung, and Morf [J. Math. Anal. Appl., 68 (1979), pp. 395–407]. The concluding stage of the computations is the recovery of the output from its compressed representation via the associated displacement operator L. The recovery amounts to the inversio...

Realizing that conduction currents couldn’t sufficiently explain the behavior of capacitors, Maxwell postulated the existence of displacement currents and changed the face of electromagnetics forever. Conduction currents (Jf ) involve the transport of “free” electrical charges, and in Ampere’s law (∇×H = Jf ) they are the sole source of curled magnetic fields. Maxwell realized that time-varying...

In this paper, a displacement-constrained volume-minimizing topology optimization model is present for two-dimensional continuum problems. The new model is a generalization of the displacement-constrained volume-minimizing model developed by Yi and Sui [1] in which the displacement is constrained in the loading point. In the original model the displacement constraint was formulated as an equali...

An enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. At first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. The advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

Some structural control systems have been devised to protect structures against earthquakes, which the tuned mass damper (TMD) being one of the earliest. The effect of a tuned mass damper depends on its properties, such as mass, damping coefficient, and stiffness. The parameters of tuned mass dampers need to be tuned based on the main system and applied load. In most of the papers, the paramete...
