A MODULUS ITERATION METHOD FOR NONNEGATIVELY CONSTRAINED PHOTOACOUSTIC IMAGE RECONSTRUCTION

Journal of Applied Analysis & Computation
Summary: The photoacoustic tomography (PAT) is a new biomedical imaging modality. Its assistance in early clinical diagnosis has become more and more important in the medical field. In the PAT imaging system, when a beam of short-pulsed laser irradiates the biological tissue, the photoacoustic effect results in the generation of the acoustic waves in ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

Advanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

Performance Improvement of QPSK Signal Predetection EGC Diversity Receiver [PDF]

, 2012
This paper proposes a modification of quadrature phase-shift-keying (QPSK) signal diversity reception with predetection equal gain combiner (EGC). The EGC combining is realized by using the constant modulus algorithm (CMA).

Assessment of spread foundation settlement using statistical determination of characteristic values of subsoil properties

Studia Geotechnica et Mechanica
According to Eurocode 7, limit state design codes generally draw more attention to ultimate limit states than to serviceability limit states. This paper presents the problem of settlement assessment of spread foundations on clays when the foundation ...

Data on tensile tests and NMR measurements of poly(vinilidene fluoride) before and after stress relaxation

Data in Brief, 2018
Poly(vinilidene fluoride) was characterized before and after stress relaxation by tensile tests and time-domain nuclear magnetic resonance (TD-NMR). Tensile tests were performed to provide mechanical properties, focused on the data of elastic modulus for

Bayesian changepoint analysis for atomic force microscopy and soft material indentation

, 2008
Material indentation studies, in which a probe is brought into controlled physical contact with an experimental sample, have long been a primary means by which scientists characterize the mechanical properties of materials.
