The aluminum alloys D16 and AMg6 were irradiated using the high-current relativistic electron beam in vacuum. Intense electron irradiation of the materials modified their physical properties. The fractal character of the...

Abstract This study investigates the evolving urban morphology and landscape fragmentation in Kuwait by integrating fractal analysis, spatial statistics, and landscape metrics. Utilizing historical land use and land cove...

Abstract The Pehlivan chaotic system, introduced by Ibrahim Pehlivan and Yilmaz Uyaroglu, is a three-dimensional autonomous chaotic model with rich dynamical properties. This paper develops a numerical framework for the ...

A pressing issue in materials science is the controlled application of ceramic composite materials at high temperatures in modern technologies, particularly in nuclear physics, atomic energy, aerospace, and rocket engine...

Background. The increase in technogenic electromagnetic load leaves open the question of its impact on living cells, which do not have a specific evolutionary mechanism for responding to such an environmental factor. Cur...

Cone-beam computed tomography (CBCT) is becoming more widely used in the field of dentomaxillofacial radiography, but its utility for bone quality assessment is still limited. This study was conducted to describe the use...

Abstract The design and characterization of single and multi-layered miniaturized microstrip antennas resonating at 2.4 GHz are proposed. The miniaturization is accomplished by fractal Defected Ground Structure (DGS). Th...

We study the temporal correlations in the evolution of the order parameter ϕt for the Vicsek model with vectorial noise by estimating its Hurst exponent H with detrended fluctuation analysis (DFA). We present results on...

The temporal dynamics in biological systems displays a wide range of behaviors, from periodic oscillations, as in rhythms, bursts, long-range (fractal) correlations, chaotic dynamics up to brown and white noise. Herein, ...

In order to obtain the criteria and precursor characteristics of critical rock fracture, laboratory experiments on the characteristics of acoustic emission (AE) of gritstone specimens under uniaxial compression are carri...

This study investigates the failure and energy dissipation patterns of tuff under impact loads with varying occurrence conditions in Dahongshan Copper Mine through Split Hopkinson pressure bar (SHPB) tests, digital image...

The efficiency and longevity of photovoltaic (PV) systems are fundamentally constrained by excessive operating temperatures, which reduce electrical output and accelerate material degradation. To address this issue, this...

Resumo Este artigo objetiva refletir acerca das interações entre formação e ação ergonômica, especificamente, na perspectiva da Ergonomia da Atividade. Seu ponto de partida é a trajetória histórica dessa interf...

Urban Green Infrastructure (UGI) provides multiple benefits, but these are being greatly eroded by urbanization and declining connectivity, which threaten biodiversity in urban centres. This study therefore investigated ...

This study investigates the effect of discharge voltage on fracture distribution and fragmentation extent in multi-hole pulsed discharge rock fragmentation. Comparative experiments were conducted on red sandstone specime...

Understanding the strain-damage-energy dissipation mechanisms and evolution characteristics of deep coal and rock under impact loading is of great significance for the prevention and control of rockbursts. In this study,...

Abstract The hydro-viscous drive (HVD) has been widely used in fan transmission in vehicles, fans, and scraper conveyors for step-less speed regulation or soft starting. In the mixed friction stage, the contact, friction...

ABSTRACT Transition metal ions have been implicated in modulation the conformational behavior and aggregation of WT α‐synuclein (WT‐αSyn), associated with Parkinson's disease pathology. Nevertheless, the initial st...

In this paper, a method for representing scalar functions on volumes is presented. The method is based on wavelets and it can be used for representing volumetric data (geometric or scalar) defifined on non structured gri...
