Aims/Purpose: Vogt‐Koyanagi‐Harada syndrome (VKH) is an autoimmune disease characterized by a chronic bilateral granulomatous panuveitis accompanied extraocular manifestations, namely of the nervous, auditory, and integumentary systems. Retinal changes documented optical coherence tomography (OCT) were found to have prognostic value, including detachments between retinal layers with fluid accumulation. The aim this study was estimate total detachment volume (TDV) accumulation that...

Reliability assessment in traditional power distribution systems has played a key role system planning, design, and operation. Recently, new information communication technologies have been introduced automation asset management, making the network even more complex. In order to achieve efficient energy grid adopt configuration operational conditions that are changing paradigm of actual electrical system. Therefore, emergence cyber-physical concept face future energetic needs requires...
Metallic electrodes are widely used in many applications, the analysis of their frequency-domain behavior is an important subject, particularly applications related to earthing/grounding systems, from dc up into MHz range. In this paper, a numerical evaluation frequency-dependent complex impedance hemispherical ground electrode implemented. A closed-form solution for non-zero frequencies still difficult task achieve as evidenced previous paper dedicated subject and, therefore, approaches...
In order to increase the versatility of additive manufacturing multimaterial processes, a hybrid system has been developed, which is capable combining 3D printing technology by DLP (Digital Light Processing) with two-dimensional Drop-on-Demand Inkjet system. Through based on digital micromirror devices (DMDs) it possible build up geometries layer-by-layer using polymerization photosensitive resins. Concurrently, while construction process performed, InkJet used deposit tiny drops conductive...
The world’s water infrastructures suffer from inefficiencies, such as high energy consumption and losses due to inadequate management practices feeble pressure regulation, leading frequent losses. This strains vital resources, especially in the face of worsening challenges climate change population growth.

This paper investigates the influence of spectral irradiance variation and response (SR) on production energy by photovoltaic cells. To determine impact SR m-Si perovskite cells, experimental tests were conducted outdoors, used optical filters to select different zones spectrum. For computational simulations modules, when subjected a certain irradiance, model with factor (SF) was implemented. The SF accurately simulated experiments performed for high-pass filters. highest relative errors...
