Head-related transfer function (HRTF) filters are used in virtual auditory displays for the binaural synthesis of the direction of a sound source over headphones. Once low-order HRTF filters are designed, the interpolation of these filters becomes an important issue for the synthesis of moving sound sources. An HRTF filter interpolation method based on the displacement of HRTF filter roots is proposed. It is possible to obtain a minimum-phase interpolated filter given that the original filters are also minimum-phase. The computational complexity of the method is the lower than that of the linear interpolation of magnitude responses.

Compensation of Friction Effects in Gyro-Stabilized Motion Platforms Sincar, Eyyup; Balkan, Raif Tuna; Platin, Bülent Emre (2015-07-03) A frequent problem encountered in the stabilization of gyro-stabilized motion platforms is the disturbance rejection associated with moving components. Due to relative motion of adjacent components, friction is induced by the destabilizing force from the base motion to the stabilized object, degrading its motion accuracy. Hence, a compensation of frictional effects is necessary in order to obtain a highly precise stabilization performance. In this paper, applications of both single-state disturbance observe...
Conversion Efficiency Calculations for Soft X-Rays Emitted from Tin Plasma for Lithography Applications Demir, P.; Demir, P.; KAÇAR, ELİF; Bilikmen, S. K.; DEMİR, ALİ (2008-08-22) Laser-produced plasmas can be used as extreme ultraviolet (EUV) sources for lithography, operating in the 13.5 nm range. Soft X-rays emitted from laser-produced tin plasma were simulated using the EHYBRID code. Required atomic data for tin ions were calculated using the Cowan code. In the EHYBRID simulations tin stab target is assumed to be irradiated by 1064 nm wavelength Nd:YAG laser. Simulations were performed for different driving laser parameters.
Blind source separation and directional audio synthesis for binaural auralization of multiple sound sources using microphone array recordings Günel Kılıç, Banu; Hacıhabiboğlu, Hüseyin (2008-01-01) Microphone array signal processing techniques are extensively used for sound source localisation, acoustical characterisation and sound source separation, which are related to audio analysis. However, the use of microphone arrays for auralisation, which is generally related to synthesis, has been limited so far. This paper proposes a method for binaural auralisation of multiple sound sources based on blind source separation (BSS) and binaural audio synthesis. A BSS algorithm is introduced that exploits the ...
Spherical harmonics based acoustic scene analysis for object-based audio Çöteli, Mert Burkay; Hacıhabiboğlu, Hüseyin; Department of Information Systems (2021-2-19) Object-based audio relies on elemental audio signals from individual sound sources and their associated metadata to be reconstructed at the listener side. While defining audio objects in a production setting is straightforward, it is not trivial to extract audio objects from more realistic recording scenarios such as concerts. Thus, existing object-based audio standards also define scene-based formats alongside objectbased representations that provide immersive audio, but without the flexibility provided by...
Texture segmentation using the mixtures of principal component analyzers Musa, MEM; Duin, RPW; de Ridder, D; Atalay, Mehmet Volkan (2003-01-01) The problem of segmenting an image into several modalities representing different textures can be modelled using Gaussian mixtures. Moreover, texture image patches when translated, rotated or scaled lie in low dimensional subspaces of the high-dimensional space spanned by the grey values. These two aspects make the mixture of local subspace models worth consideration for segmenting this type of images. In recent years a number of mixtures of local PCA models have been proposed. Most of these models require ...
