Interpolation of low order HRTF filters using a zero displacement measure

Head-related transfer functions (HRTF) are generally measured at discrete azimuth and elevation values. Continuous motion of virtual sound images can only be obtained by interpolation of HRTFs for intermediate azimuth and elevation values in an immersive audio system. HRTFs can be modelled as a combination of low-order minimum-phase finite impulse response (FIR) filters and a constant delay line. A new method for interpolation of FIR filter zeros using a proximity-based vectorial displacement measure is proposed in this work.

Intersonic delamination in curved thick composite laminates under quasi-static loading
Gozluklu, Burak; Uyar, Imren; Çöker, Demirkan (2015-01-01)
Dynamic delamination in curved composite laminates is investigated experimentally and numerically. The laminate is 12-ply graphite/epoxy woven fabric L-shaped laminate subject to quasi-static loading perpendicular to one arm. Delamination initiation and propagation are observed using high speed camera and load displacement data is recorded. The quasistatic shear loading initiates delamination at the curved region which propagates faster than the shear wave speed of the material, leading to intersonic delami...
Probabilistic distance clustering adjusted for cluster size
BEN-ISRAEL, Adi; İyigün, Cem (Cambridge University Press (CUP), 2008-01-01)
The probabilistic distance clustering method of [1] works well if the cluster sizes are approximately equal. We modify that method to deal with clusters of arbitrary size and for problems where the cluster sizes are themselves unknowns that need to be estimated. In the latter case, our method is a viable alternative to the expectation-maximization (EM) method.
Estimating Brain Connectivity for Pattern Analysis
Onal, Itir; Aksan, Emre; Velioglu, Burak; Firat, Orhan; Ozay, Mete; GİLLAM, İLKE; Yarman Vural, Fatoş Tunay (2014-04-25)
In this study, the degree of connectivity for each voxel, which is the unit element of functional Magnetic Resonance Imaging (fMRI) data, with its neighboring voxels is estimated. The neighborhood system is defined by spatial connectivity metrics and a local mesh of variable size is formed around each voxel using spatial neighborhood. Then, the mesh arc weights, called Mesh Arc Descriptors (MAD), are used to represent each voxel rather than its own intensity value measured by functional Magnetic Resonance I...
Effect of thermal induced flexural strain cycles on the low cycle fatigue performance of integral bridge steel H-piles
Karalar, Memduh; Dicleli, Murat (2016-10-01)
Close examination of the field measurement data for integral bridges revealed that the measured cyclic flexural strains in steel H-piles at the abutments due to thermal fluctuations consist of large amplitude, primary small amplitude and secondary small amplitude cycles. The effect of the small amplitude strain cycles on the low cycle fatigue life of these steel H-piles has not been extensively studied yet. Accordingly, to investigate the effect of the small amplitude strain cycles on the low cycle fatigue ...
A Class of Nonisothermal Variable Thickness Rotating Disk Problems Solved by Hypergeometric Functions
Eraslan, Ahmet Nedim (2005-06-01)
Exact solutions for nonisothermal variable thickness rotating disks represented by different thickness profiles are obtained under plane stress assumption. The solutions are based on Tresca's yield criterion, its associated flow rule and linear strain hardening material behavior. Five different plastic regimes governed by different mathematical forms of the yield criterion are considered for each thickness profile. A displacement formulation is used and the resulting differential equations for the elastic a...
