The influence of dynamic change in the steering angle of incident and scattered wave beams on the spectra of the ultrasonic Doppler response is studied on the basis of the previously developed continuum model of ultrasound waves scattering in biological o... see more

The previously developed continuum model of ultrasound wave scattering from inhomogeneities of mass density and compressibility was generalized in the present paper to the case of dynamically changing sensitivity function of ultrasound diagnostic sys... see more

We often introduce regulatory constraints or behavioral indications to control or avoid diffusion processes with nontrivial social interactions. Examples are a pandemic or circumstances dealing with construction and management of civil structures, such as... see more

Complex formation between a natural polysaccharide – gellan and an antimicrobial drug – ofloxacin was studied in aqueous solution. Conductimetric and potentiometric titration curves revealed that gellan and ofloxacin forms a water-soluble complex of compo... see more

Scattering media environments are real-world conditions that occur often, in daily life. Some examples of scattering media are haze, fog, and other bad weather conditions. In these environments, micro-particles in the surrounding media interfere with ligh... see more

The  objective  of  the  work  carried  out  in  this  research  was  to  develop  analytical  and computational  tools  to  model  and  investigate  muscu... see more

using the matching method formalism, this work presents the transmission and reflection coefficients of coherent phonons in a quasi 2D quantum waveguide perturbed by reticular defects as interstitial impurities. Our waveguide is modelled by two infinite a... see more

Improvement on Inter Carrier Interference (ICI)mitigation techniques for OFDM caused by Doppler effectsthrough minimizing channel estimation error and decreasingchannel time varying rate is investigated. The performanceof pilot-aided channel estimation te... see more

Las directrices del Espacio Europeo de Educación Superior (EEES) hacen necesario el replanteamiento de muchos de los modelos evaluativos actuales. Este artículo presenta un modelo de evaluación alternativa aplicado en la asignatura de Gestión Cultural del... see more
