Acoustic signal localization through the use of Head Related Transfer Functions [PDF]
Journal of Systemics, Cybernetics and Informatics, 2004 An acoustic image of space is an acoustically described visual image intended to help blind people orient themselves in space. Description is made with the aid of spatial sounds created using HRTF filters. HRTF filters are empirically acquired FIR filter

Proceedings of the American Mathematical Society, 1993 Subspaces sufficiently near an arbitrary (fixed) subspace of a Hilbert space are shown to be in one-to-one correspondence with operators defined on the given subspace. Specifically, the nearby subspaces can be regarded as the graphs of these operators. This is applied to explicitly define a

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Advanced Electronic Materials, EarlyView.Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations
Advanced Electronic Materials, EarlyView.This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐

Explicit subspace designs [PDF]
Combinatorica, 2013 An \((s,A)\) subspace design is a set of linear subspaces \(H_1, \dots, H_M\) of \(F_q^m\) such that for every \(s\)-dimensional subspace \(W\) of \(F_q^m\) at most \(A\) of the \(H_i\) intersect \(W\) non-trivially. In this paper, the authors refine the construction of the first author and \textit{C.

Dual subspace discriminative projection learning
, 2021 In this paper, we propose a dual subspace discriminative projection learning (DSDPL) framework for multi-category image classification. Our approach reflects the notion that images are composed of class-shared information, class-specific information, and

Advanced Energy Materials, EarlyView.Kinetic–energetic projection of time‐resolved photoluminescence reveals that charge‐transfer injection acts as a universal bottleneck in organic solar cells. A physics‐constrained Bayesian framework identifies an emergent effective CT injection rate governing the trade‐off between charge generation and nonradiative energy loss.

Subspace Procrustes Analysis [PDF]
International Journal of Computer Vision, 2015 Procrustes Analysis (PA) has been a popular technique to align and build 2-D statistical models of shapes. Given a set of 2-D shapes PA is applied to remove rigid transformations. Then, a non-rigid 2-D model is computed by modeling (e.g., PCA) the residual.

Geometrical aspects of subspace codes [PDF]
, 2018 Subspace codes are codes whose codewords are equal to subspaces of a finite vector space V(n, q). Since the geometry of the subspaces of a finite vector space V(n, q) is equivalent to the geometry of the subspaces of a projective space PG(n−1,q ...
