Application of the frequency domain acoustic wave equation on data acquired from ultrasound tomography scans is shown to yield high resolution sound speed images order wavelength highest reconstructed frequency. Using a signal bandwidth 0.4–1 MHz and an average 1500 m s−1, approximately 1.5 mm. The quantitative values morphology provided by these have potential inform diagnosis classification breast disease. In this study, we present formalism, practical application, in vivo results waveform...
Many signal processing algorithms include numerical problems where the solution is obtained by adjusting value of parameters such that a specific matrix exhibits rank deficiency. Since minimization generally not practicable owing to its integer nature, we propose real-valued extension term effective rank. After proving some properties, provided with an operational meaning using result on coefficient rate stationary random process. Finally, proposed measure assessed in practical scenario and...
Logic and game theory have had a few decades of contacts by now, with the classical results epistemic as major high-lights. In this paper, we emphasize recent new perspective toward “logical dynamics”, designing logical systems that focus on actions change information, preference, other driving forces agency. We show how dynamic turn works out for games, drawing some advances in literature. Our key examples are long-term dynamics information exchange, well much-discussed issue extensive...
We present preliminary results obtained using a time domain wave-based reconstruction algorithm for an ultrasound transmission tomography scanner with circular geometry. While comprehensive description of this type has already been given elsewhere, the focus work is on some practical issues arising approach. In fact, methods suffer from two major drawbacks which limit their application in setting: convergence difficult to obtain and computational cost prohibitive. address first problem by...
We describe the technical design and performance of SoftVue, a breast imaging device based on principles ultrasound tomography. SoftVue's sensor is ring shaped transducer operating at 3 MHz consisting 2048 elements. Data acquisition achieved through 512 receive channels. The encircles breast, which immersed in warm water while patient lies prone position. translated vertically to acquire data from entire breast. acquired are used reconstruct images using tomographic inversions....
We study the distributed sampling and centralized reconstruction of two correlated signals, modeled as input output an unknown sparse filtering operation. This is akin to a Slepian-Wolf setup, but in rather than lossless compression case. Two different scenarios are considered: In case universal reconstruction, we look for sensing recovery mechanism that works all possible whereas what call almost sure allow have small set (with measure zero) unrecoverable signals. derive achievability...
Hearing aids are electronic, battery-operated sensing devices which aim at compensating various kinds of hearing impairments. Recent advances in low-power electronics coupled with progresses made digital signal processing offer the potential for substantial improvements over state-of-the-art systems. Nevertheless, efficient noise reduction complex listening scenarios remains a challenging task, partly due to limited number microphones that can be integrated on such devices. We investigate...
Ultrasound tomography is an emerging modality for breast imaging. However, most current ultrasonic imaging algorithms, historically hindered by the limited memory and processor speed of computers, are based on ray theory assume a homogeneous background which inaccurate complex heterogeneous regions. Therefore, wave theory, accounts diffraction effects, must be used in algorithms to properly handle nature tissue order accurately image small lesions. application waveform medical has been...
Abstract We introduce a new understanding of deontic modals that we call obligations as weakest permissions . argue for its philosophical plausibility, study expressive power in neighborhood models, provide complete Hilbert-style axiom system it and show can be extended applied to practical norms decision game theory.
Performance of the novel high repetition rate HF-PW laser system ELI ALPS is presented in its first operation phase at 400 TW and 700 levels. Long-term was tested 2.5 10 Hz rates, where an exceptional 0.66% 1.08% shot-to-shot energy stability demonstrated, respectively. Thorough spatio-spectral temporal measurements confirmed quality output pulses with a Strehl ratio >0.9 after compression both rates. Amplified unprecedentedly 240 W average power were reached for time from PW-class...
Distributed estimation of an unknown signal is a common task in sensor networks. The scenario usually envisioned consists several nodes, each making observation correlated with the interest. acquired data then wirelessly transmitted to fusion center that aims at estimating desired within prescribed accuracy. Motivated by obvious processing limitations inherent such distributed infrastructures, we seek find efficient compression schemes account for limited available power and communication...
Résumé Suivant le postulat selon lequel traitement isolé des motifs de discrimination contribue à la marginalisation individus et groupes subissant discriminations multiples imbriquées, l'article examine processus d'intégration l'intersectionnalité dans pratique judiciaire antidiscriminatoire canadienne.

A number of clinical trials have shown that screening ultrasound, supplemental to mammography, detects additional cancers in women with dense breasts. However, labor intensity, operator dependence and high recall rates limited adoption. This paper describes the use ultrasound tomography for whole-breast tissue stiffness measurements as a first step toward addressing issue rates. The validation technique using an anthropomorphic phantom is described. In-vivo applications are demonstrated on...
