In this research, the development of a novel brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO)-based homogeneous anion exchange membrane (AEM) via solution casting method was reported. Fourier transform infrared spectroscopy used to confirm successful BPPO-based AEM. The prepared AEM showed excellent thermal stability. It exhibited an ion capacity 2.66 mg/g, water uptake (WR) 68%, and linear swelling ratio 31%. Methyl orange (MO), anionic dye, as model pollutant evaluate ability...
<abstract><p>Many techniques have been recently employed by researchers to address the challenges posed fractional differential equations. In this paper, we investigate concept of Ulam-Hyers stability for a class neutral stochastic equations using Banach fixed point theorem and analysis techniques. An example is presented at end paper show interest applicability results.</p></abstract>
In this study, a numerical investigation of photonic quasi-periodic Generalized Fibonacci (GF) (m, n) sequences is carried out in the visible spectrum. The transfer matrix method employed to study behavior wave propagation through structures. Firstly and highlight importance GF structure, its transmittance spectrum compared those periodic ordinary It shown that structure permits one obtain multi-photonic band gaps (PBGs) separated by several resonance modes. variation parameter m 1) allows...
This paper tackles the control problem of nonlinear disturbed polynomial systems using formalism output feedback linearization and a subsequent sliding mode design. aims to ensure asymptotic stability an unstable equilibrium point. The class under investigation has equivalent Byrnes–Isidori normal form, which reveals stable zero dynamics. For case modeling uncertainties and/or process dynamic disturbances, conventional linearizing strategies may fail be efficient. To design robust strategy,...
Using the transfer matrix method, electromagnetic responses of 1D deformed and non-deformed quasi-periodic photonic crystals arranged in accordance with Fibonacci sequence are theoretically studied. The gallium selenide (GeSe) plasma materials (that is, electron density) used to construct multilayer structures. If this study is experimentally validated future, we intend insert two transparent polymer film at top bottom structure, which intended protect material prevent it from escaping...
The main purpose of this research paper is to investigate the role information and communication technology (ICT) in providing small medium-sized enterprises (SMEs) with a competitive advantage. To do this, we propose five dimensions detect ICT (human resources, equipment devices, databases, software, networks) four (service quality, market control, creativity development, operational efficiency) decide achieve paper’s purposes, questionnaire was developed collect data from respondents...
The concept of competitiveness has had a notable influence on the strategies and policies adopted recently. In particular, regional attracted significant interest from policymakers due to its capacity assess compare different territories in absence an established policy or conceptual framework. Nevertheless, itself been topic debate among scholars, along with dimensions that should be included such concept. aim this study is examine evaluate competitive landscape at level Saudi Arabia....
The multiple-assignments approach alleviates the quantization error and enhances accuracy of Content-Based Image Retrieval (CBIR) systems. It aims to hard assign each feature vector k-nearest visual words. However, during matching step, words are used independently ignore significant best word. In this paper, we present our CBIR system which encapsulates several approaches such Hamming embedding, soft-assignment, graph fusion. We particularly focus on strategy. propose an efficient soft...
When the AlGaN/GaN high electron mobility transistor (HEMT) is strongly biased, speed of electrons in channel increases, which leads to an injection into buffer, and consequently appearance "short effect" phenomenon, limits performance component overcome this effect increase power/frequency component, one solution consists using a confinement barrier. This involves placing electrostatic barrier under GaN so as block buffer layer when highly BGaN because semiconductor has very interesting...
