A novel approach—integrating a simulated annealing (SA) algorithm with deep learning (DL) acceleration—is presented for the rapid and accurate development of terahertz perfect absorbers through forward prediction backward design. The neural network (FNN) effectively deduces absorption spectrum based on metasurface geometry, resulting in an 80,000-fold increase computational speed compared to full-wave solver. Furthermore, absorber’s structure can be precisely promptly derived from desired...
In the cultivation of green chili peppers, similarity between fruit and background color, along with severe occlusion fruits leaves, significantly reduces efficiency harvesting robots. While increasing model depth can enhance detection accuracy, complex models are often difficult to deploy on low-cost agricultural devices. This paper presents an improved lightweight Pepper-YOLO based YOLOv8n-Pose, designed for simultaneous peppers picking points. The proposed introduces a reversible dual...
In this paper we have analyzed the performance of a general null steering algorithm by simulation studies for expected OISR and standard deviation different signal to noise level number samples. We also studied special case approach compared value using definition approximate expression The results show that approximation E{OSIR} (eq.8) is not accurate enough even in where higher SNR, large T, distanced sources were used. These are useful predicting asymptotic an open-loop adaptive system...
We propose a small GPS anti-jam antenna. The method is based on adaptive null-steering processing with miniature antenna elements. Our system can maintain tacking and adaptively steering null(s) for optimal performance. technology provides the performance advantages of array in footprint antenna, allowing an increase without significant size or cost.
Tubular solder joint detection is an important and challenging issue in the industry, due to illegible objects, rarely collected datasets requiring high-precision real-time performance for positioning angle estimation. In this article, we propose Attention integrated Cross-spatial feature fused Rotation Network (ACR-Net) tubular detection, which consists of a new extraction network named ECA-CSPDarknet44, cross-spatial fusion (CFFN), bin-based rotation (BRDN). The proposed can efficiently...
We have developed a sequential beamspace method for high resolution direction of arrival (DOA) estimation. Beamspace MUSIC and element space DOA estimation algorithms been implemented to utilize an 8 uniform circular array operating at 5.8 GHz. The simulation initial lab results show that the proposed can achieve good accuracy once it is properly sychronized. In addition, significant decrease in hardware realized when versus space.
This paper investigates scheduling problems on m parallel identical machines with non-simultaneous machine available times. Each M <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i</sub> is not until time r . Jobs arrive one by one, and we are required to schedule jobs irrevocably as soon they given, without any knowledge of the successive jobs. We study semi-online version problem while known largest processing all in advance, objective...
In the new scientific and technological revolution round, artificial intelligence (AI) technology has become a key leading force for industrial change. Research shows that AI not only promoted technical transformation industry upgrades but also played significant role in rapid development of emerging industries. Based on installed number robots data by National Bureau Statistics, this study establishes theoretical framework with econometric model compares impact different categories...
Abstract We investigate the planar ninth degree non-analytic Poincare systems which have center-focus equilibriums at origins. Those could be changed into analytic by two transformations with help of computer algebra system MATHEMATICA. The conditions uniform isochronous center are obtained. Furthermore, we prove that five limit cycles bifurcated from origin. MSC: 34C05, 34C07.
A novel planar magneto-electric (ME) dipole antenna is presented for ultra-wideband (UWB) applications. The proposed structure consists of a co-excited self-complementary rounded edge bow-tie and half-loop antenna. avoids the use balun tuning-matching circuit over an UWB, thus reducing overall size associated loss. CST simulations were performed. prototype was fabricated measured. Lab tests demonstrated basic performance.
While coupling between two parallel thin wire loops has been considered in the past, orthogonal not discussed to our knowledge. With increasing interest compact complete polarization diversity antennas, it becomes important understand closely located orthogonally oriented antenna elements. Coupling collocated is analyzed. Two coupled integral equations for loop currents are derived and their solution general form found terms of a Fourier series. It that strong can exist first higher current...
