The national rural revitalization strategy has advanced, and new requirements for modern internet-of-things (IoT)-based farm supervision tools have been proposed. This study proposes a “you-only-look-once” (YOLO) v5 convolutional neural network to optimize the candidate frame's center point algorithm. Five YOLOv5 models are used to identify and classify captive pigs. According to the experimental results, the K-median algorithm has a better effect than using the K-means algorithm, and its average intersection over union is approximately 1-2% higher. In our scenario, the commercial application value of the YOLOv5s model is higher, and the corresponding performance results of F1-score, mAP0.5, mAP0.5:0.95, FPS, and R 2 are 92.21%, 95.18%, 64.85%, 75 FPS, and 85.54%, respectively.

Spatial layout planning in architecture is a complex, highly constrained problem with multiple objectives and wide range of possible solutions. Due to its iterative and time-consuming nature, it is desirable to automate and optimize the spatial layout design process. Here we present a procedural model with hexagonal cellular automata to automatically generate various spatial layouts from basic user inputs of design space, area, and adjacency. The user is also allowed to specify the positions of one or more spaces within the design space. The spatial layout generator can output various 2D models representing the allocated spaces that conform to all the user inputs. It is envisioned that the generated layouts can serve as design guides and alternatives to ease the tedious spatial layout planning process.

Multi-hop relay is regarded as a promising and effective method to provide highly reliable communication service between the control center and the terminal under a fragile and unstable industrial wireless channel environment. However, wireless communication and control in the Industrial Internet of Things (IIoT) are tightly coupled, making multi-hop relay path construction more challenging. Therefore, we propose an efficient multi-hop relay node selection algorithm to decrease the control cost of the closed-loop system to ensure the stability of the system. Specifically, we establish the relationship between node selection and control cost using the age of information as an intermediary. Then, an improved elite ant colony (IEACO) algorithm is proposed to find a relay path to minimize control cost so as to ensure the system quickly converges to a stable state. Finally, we carried out extensive experiments to verify the effectiveness of the proposed algorithm, and the results reveal that the IEACO algorithm can achieve the approximately optimal control performance. Specifically, in the example of the temperature control system, the IEACO algorithm can also make the system reach the stable state faster and improve the convergence performance by about 5% to 30%.

Aiming to the problem of determining the signal source of speech signals with different sampling rates, a method is proposed to match speech signals with different sampling rates. This method performs bilinear interpolation on the speech signal with the smaller sampling rate to transform its sampling rate, making the sampling rates of the two digital speech signals approximately equal. Then, it calculates the cross-correlation function of the two digital speech signals. Based on the observation of significant correlation peaks, it calculates the peak-to-mean ratio of the cross-correlation function and the sliding correlation coefficient to determine if the speech signals are from the same source. Simulation results show that this method can effectively determine whether two speech signals with different sampling rates belong to the same speech signal source.

In robotics, inverse kinematics (IK) consist in finding the actuation solution needed for a robotic system to achieve a given work position. Traditional analytical methods may suffer from singularities and may be time consuming especially for manipulators with high degrees of freedom (DoF). This paper proses a new neural metaheuristic approach, consisting in embedding a neural network within a swarm, where the neural network will be generating a first solution which considered as the starting configuration of the swarm. The swarm will then prospect better solutions if needed while starting from the neural network initial position. The approach is called the neural-meta-swarm, N-M-swarm. This paper is a typical implementation of the approach where an artificial neural networks in embedded in the initialization process of the Dragonfly Algorithm. The ANN is trained on forward kinematics data to map end-effector positions to joint angles, while the DA optimizes the ANN's up to the needed precision. Experimental results demonstrate that this method retuned acceptable results for a 4 DoF manipulator. N-DA showed also acceptable performance for an approximated circular path planning.

The increasing penetration of renewable energy sources (RES) introduces high uncertainty and poses significant challenges to operational security in power systems. This paper proposes a novel probabilistic operational security region (POSR) model for high-penetration RES in power systems, which is based on non-parametric probabilistic forecasting to quantify RES uncertainty. The POSR model provides a local equivalent approximation of RES feasible region incorporating system operational constraints, thereby enhancing computational efficiency in high-dimensional spaces. An innovative POSR-solving algorithm is also developed, leveraging region credibility hyper-box settings and convex hull boundaries to rapidly iterate boundaries. Case studies based on IEEE 33-bus and 141-bus systems validate the effectiveness of the proposed POSR model with high computational efficiency.

We propose a linear cutting-plane pricing algorithm tailored for large-scale electricity markets, addressing nonconvexities arising from the Alternating Current Optimal Power Flow equations. We benchmark our algorithm against a Direct Current (DC) approximation and the Jabr Second-Order Cone (SOC) relaxation under both the Integer Programming and Convex Hull pricing rules. We provide numerical results for a small (617-bus) and three large (≥ 15, 000-bus) networks. Our algorithm yields price signals very close to the Jabr SOC, with computation times comparable to DC once we allow for warm-starts, including scenarios with line contingencies. © 2025, CC BY.

Integrated sensing and communication (ISAC) has garnered considerable attention for its capacity to simultaneously communicate and sense the surrounding environment. To enhance ISAC systems, non-orthogonal multiple access (NOMA) can be leveraged to mitigate interference between communication and sensing functions. This paper explores the transceiver design and mode selection for NOMA-ISAC in network-assisted fullduplex (NAFD) cell-free massive multiple-input multiple-output (mMIMO) systems. We firstly derive expressions for both the data rates of communication users and the sensing signal-to-interference-plus-noise ratios (SINRs) of radar targets. Subsequently, we formulate a joint optimization problem aimed at maximizing the sum sensing SINR while respecting communication constraints. To address this, we propose an algorithm based on sequential convex approximation (SCA) coupled with simulated annealing (SA) to obtain the optimal solution. Simulation results demonstrate the efficacy of our proposed algorithm in significantly enhancing system performance.

This study addresses the agricultural planting strategy optimization problem in North China's mountainous area by constructing three progressively in-depth mathematical models. These models consider factors such as planting restrictions, sales, and cost assumptions. An Improved Grey Wolf Optimization algorithm (IGWO) is proposed to solve the established mathematical models. Compared with the standard GWO algorithm, the particle swarm optimization (PSO) algorithm, and the differential evolution (DE) algorithm, the IGWO algorithm increases the economic benefits of agricultural planting structure by approximately 15%. Additionally, the ecological protection index is improved by 10%, and the social development index is increased by 8 %. This research provides a novel approach and perspective for optimizing agricultural planting structures.

Geometric Localization of Homology Cycles

Computing an optimal cycle in a given homology class, also referred to as the homology localization problem, is known to be an NP-hard problem in general. Furthermore, there is currently no known optimality criterion that localizes classes geometrically and admits a stability property under the setting of persistent homology. We present a geometric optimization of the cycles that is computable in polynomial time and is stable in an approximate sense. Tailoring our search criterion to different settings, we obtain various optimization problems like optimal homologous cycle, minimum homology basis, and minimum persistent homology basis. In practice, the (trivial) exact algorithm is computationally expensive despite having a worst case polynomial runtime. Therefore, we design approximation algorithms for the above problems and study their performance experimentally. These algorithms have reasonable runtimes for moderate sized datasets and the cycles computed by these algorithms are consistently of high quality as demonstrated via experiments on multiple datasets. © 2024, CC BY.
