In this communication, a novel wideband differentially fed dual-polarized stacked patch antenna with tuned slot excitations for base station application is proposed. The composed of driven excited by excitations, parasitic to enhance the impedance bandwidth, and ground plane obtain unidirectional radiation. Two pairs etched on opposite edges are used dual polarizations. Each excitation has an open-ended Γ-shaped feeding line. To connect differential circuit easily, rotated mechanism adopted....
A trapezoid monopole antenna with dual band‐notched characteristics for UWB is presented. The consists of a patch and rectangular ground plane. To realise notched‐band characteristics, U‐shaped stub T‐shaped are embedded in two slots the radiation patch, respectively. measured results show that proposed notched‐bands planar has an impedance bandwidth 3–11 GHz VSWR < 2, except frequency notched bands 3.3–3.7 (WiMAX band) 5.15–5.825 (WLAN band). Both simulated presented, indicating good...
Abstract Global Navigation Satellite System (GNSS) based velocity estimation is one of the most cost-effective and widely used methods in determining geodesy transport applications. Highly accurate reliable measurements can be obtained by exploiting raw Doppler, carrier phase, pseudorange with a GNSS receiver. There are several approaches to GNSS-based determination. This paper investigates characteristics which currently popular applicable observations Positioning (GPS), BeiDou (BDS), their...
Communities in multi-layer networks consist of nodes with similar connectivity patterns across all layers. This article proposes a tensor-based community detection method networks, which leverages available node-wise covariates to improve accuracy. is motivated by the network homophily principle, suggests that tend reside same community. To take advantage covariates, proposed augments an additional layer constructed from node similarity matrix proper scaling, and conducts Tucker...
A differential‐fed microstrip antenna, which is characterised with an ultra‐wideband (UWB) of 120% (3–12 GHz), improved radiation patterns, stable gains and compact size, proposed. Two symmetrical trapezoid‐shaped slots four triangle‐cut corners on the ground are used to improve impedance matching over UWB frequency band. To clarify characteristics, simulated 3D patterns proposed antenna also shown. The measured results show that, in entire band, designed exhibits a pattern gain variation...
The increasing demand for efficient last-mile delivery in smart logistics underscores the role of autonomous robots enhancing operational efficiency and reducing costs. Traditional navigation methods, which depend on high-precision maps, are resource-intensive, while learning-based approaches often struggle with generalization real-world scenarios. To address these challenges, this work proposes Openstreetmap-enhanced oPen-air sEmantic Navigation (OPEN) system that combines foundation models...
The objective of this study was to determine the effects triphenyltin (TPT) and dietary quercetin on growth, oxidative stress apoptosis in zebrafish. A total 240 fish were divided into 4 groups with three replicates as follows: fed basal diet control group (D1), only 10 ng/L TPT (D2), + 100 mg/kg (D3), mg/Kg D4 group. At end period (56 d), results showed that growth performance significantly higher than exposed TPT. Quercetin ameliorated stress, which decreased malondialdehyde (MDA) nitric...
Abstract The Red Sea basin has good prospects for hydrocarbon exploration from recent geological and geophysical research results. Traditionally, seismic reflection, especially reflection methods, can effectively characterized the structure details of different rock layers. However, salt deposition stages significantly impede application this technology, leading to poor imaging quality below To address issues, we utilize reprocessed gravity data sets recover basement undulations beneath...
Thermal insulation gunite (TIG) in roadways is an effective method for regional thermal hazard control mines. The development of mine TIG materials the foundation technique. However, some conventional and advanced are inapplicable to deep mines which rather humid with high situ stress geo‐temperature. In this study, a kind fly ash‐inorganic mineral material was developed applied modelling geo‐temperature roadway. Moreover, effect layer analyzed, temperature field characteristics surrounding...
The aim of this paper is to study the particle size effect fly ash (FLA) on pore structure and strength Fly Ash Foamed Geopolymer (FAFG). Information macro-pores such as macro-pore distribution FAFG captured through binarization processing. Porosity compressive are respectively tested by Archimedes density test method uniaxial method. It can be concluded that FLA has an FAFG. More specifically, shows itself macroscopically quantity middle large uniformity distribution, microscopically...
Accurate prediction of the coal spontaneous combustion hazard grades is great significance to ensure safe production mines. However, traditional temperature models have low accuracy and do not predict grades. In order accurately grades, a model based on principal component analysis (PCA), case-based reasoning (CBR), fuzzy clustering (FM), snake optimization (SO) algorithm was proposed in this manuscript. Firstly, change rule concentration signature gases process warming, new method...
