This paper addresses the problem of “H∞ almost synchronization” for networks of identical, linear agents under directed communication topologies. Agents are presumed to be non-introspective; i.e. agents are not aware of their own state or output, and every agent is only provided with a linear combination of its own output relative to that of the neighbors. Providing the solvability conditions, ...

Understanding and simplified modeling of the Head Related Transfer Function (HRTF) holds the key to many applications in spatial audio. We develop an analytical solution to the problem of scattering of sound from a sphere in the vicinity of an infinite plane. Using this solution we study the influence of a nearby scattering rigid surface, on a spherical model for the HRTF.

This paper addresses the problem of “H∞ almost synchronization” for homogeneous networks of general linear agents subject to external disturbances and under directional communication links. Agents are presumed to be non-introspective; i.e. agents are not aware of their own states or outputs, and the only available information for each agent is a network measurement that is a linear combination ...

In this paper, synchronization for multi-agent systems subject to external disturbances is studied, and the notion of “H∞ almost synchronization” is introduced. The objective is to suppress the impact of disturbances on the synchronization error dynamics in terms of the H∞ norm of the corresponding closed-loop transfer function to any arbitrarily value. We focus on networks of non-identical lin...

Precomputed radiance transfer methods compute a global light transport model the transfer function to enable real-time rendering of scenes under dynamic distant illumination for arbitrary viewpoints. Usually this transfer function is represented for directions and surface points that are defined a priori. In this paper, we present a precomputed radiance transfer technique, which adaptively choo...

This paper starts with a short summary about previous work done in the field of head-related transfer function (HRTF) measurement and processing. Afterwards a new method to find and optimize HRTFs is explained. The main idea is to use expert listeners to select and tune the HRTFs with the help of real-time interaction adjustment of all parameters under test. Afterwards a listening test validate...

This paper sums up the previous research on Head-Related Transfer Function (HRTF) individualization for three-dimensional (3D) virtual auditory display. Papers which involve experiment research, theoretical computation research, and applications of 3D virtual auditory display based on HRTFs have been reviewed. The necessity of HRTF individualization is discussed based on the review of previous ...

The article presents a new audio spatialization algorithm for spatialization methods based on the headrelated transfer function (HRTF). The algorithm uses a mathematical model of the HRTF to make the spatialization process simple and fast. The article thoroughly describes this algorithm and provides a comparison of the algorithm to the traditional block convolution filtering approach.
