In this paper we address the problem of simultaneous room response equalization for multiple listeners. Traditional approaches to this problem have used a single microphone at the listening position to measure impulse responses from a loudspeaker and then use an inverse filter to correct the frequency response. The problem with that approach is that it only works well for that one point and in ...

I summarize recent observations of the kinematics of hot tracers in elliptical galaxy halos (globular clusters, planetary nebulae, and integrated stellar light), and what these tell us about the dynamics, dark matter content, and formation of ellipticals. A generic result is the ubiquity of dark matter halos in ellipticals. Studies of globular clusters and planetary nebulae are now finding oute...

Abstract. In this paper we present a hybrid approach to numerically solving two-dimensional electromagnetic inverse scattering problems, whereby the unknown scatterer is hosted by a possibly inhomogeneous background. The approach is “hybrid” in that it merges a qualitative and a quantitative method to optimize the way of exploiting the a priori information on the background within the inversion...

Gait patterns of humans and humanoid robots are often described by analysing changes in angular rotation of hip, knee and ankle joints during one gait cycle. Each joint displays specific behaviour and irregularities of the gait pattern could be detected by measuring displacements from the normal rotation curve, while small deviations of individual gait chara...

The speed, accuracy, and adaptability of human movement depends on the brain performing an inverse kinematics transformation — that is, a transformation from visual to joint angle coordinates — based on learning from experience. In human motion control, it is important to learn a feedback controller for the hand position error in the human inverse kinematics solver. This paper proposes a novel ...

We investigate a packing problem in M-dimensional grids, where bounds are given for the number of allowed entries in different axis-parallel directions. The concept is motivated from error correcting codes and from more-part Sperner theory. It is also closely related to orthogonal arrays. We prove that some packing always reaches the natural upper bound for its size, and even more, one can part...

u+1(t)_ uz(t) for tEIl r(t) f or tEIk where ui and r are the present control and a control maximizing the related Hamiltonian function, respectively. The idea of the switching scheme is based on the concept of chattering controls first proposed by Gamkrelidze. It is proved that accumulation points generated by the algorithm, if exist, satisfy maximum principle. Some examples are given to show t...

In the article a new approach for solving Markovian linear systems is presented. It is the inverse iteration with the use of the WZ factorization. The paper contains the theoretical base of the method and numerical experiment results where the accuracy and the performance time were investigated. A modified (with the use of the SBLAS library and the Harwell-Boeing sparse matrix storage scheme) m...

In this paper, we study an inexact inverse iteration with inner-outer iterations for solving the generalized eigenvalue problem Ax = Bx; and analyze how the accuracy in the inner iterations aaects the convergence of the outer iterations. By considering a special stopping criterion depending on a threshold parameter, we show that the outer iteration converges linearly with the threshold paramete...
