A traffic light control protocol is proposed, which builds compact platoons of vehicles to make efficient use of green times. It forms short platoons at multiple links and times traffic lights to concatenate these to form a single dense platoon, in which vehicles mostly passes many intersections without stopping. The protocol minimizes the number of times vehicles stop; by simulation, it roughly halves that of greenwave under near saturated demand.

Learning to Optimize Resource Allocation in Dynamic Wireless Environments: Embracing the New While Engaging the Old

IEEE Transactions on Wireless Communications 2025年

Wireless resource allocation is a critical component in modern communication systems, and deep neural networks (DNNs) have shown great promise in addressing this challenge. However, the conventional DNNs assume that testing data follows the same distribution as that of the training data, which is incongruent with the dynamic nature of real-world wireless environments. This paper introduces a new training algorithm designed specifically for dynamic wireless environments where channel distribution exhibits variability. This method helps DNNs adapt to new environments while preserving previously learned information. The proposed approach distinguishes itself by updating the DNN parameters in the null space of the low-rank covariance of previous data, which reduces memory needs and boosts training efficiency. Additionally, to counter the problem of DNNs hitting their model capacity during continuous adaptation, a selective forgetting mechanism is proposed. This mechanism allows DNNs to discard the unimportant knowledge over time, freeing up model capacity for more effective adaptation. The effectiveness of the algorithm is validated by integrating it with graph neural networks and multilayer perceptrons for weighted sum-rate maximization. Through a comprehensive evaluation that includes synthetic and ray-tracing-based datasets, superior performance is demonstrated compared to existing methods. © 2002-2012 IEEE.

Friedel-Crafts reaction and transition-metal catalysis represent primary methodologies for arene acylation; however, suffer from certain limitations, such as electronic effect-dependent reactivity, regioselectivity issues, the necessity of directing group, and relatively exceptionally limited exploration in meta-and para-acylations. N-heterocyclic carbene(NHC) catalysis has recently emerged as a promising alternative strategy for arene acylation, offering distinct regioselectivity profiles that are challenging to achieve through known methods. Herein, an NHC-mediated photo-catalytic para-selective C–H acylation of aryl alcohols is disclosed. The reaction employs a remote radical-induced temporary spiro cyclization strategy, proceeding via tandem radical dearomatization, radical acylation, rearomatization processes. Combined experimental and computational mechanistic studies support the proposed reaction pathway and observe an exclusive para-selectivity regardless of the nature of the substituents on the substrates. Despite the less satisfactory yields, the current method exhibits non-electronic nature-based reactivity and regioselectivity, enabling quick access to acylated arenes that are difficult or impossible for reported methods.

In this paper, an enhanced unified differential evolution algorithm, named UDE-III, is presented for real parameter-constrained optimization problems. The proposed UDE-III is a significantly enhanced version of the Improved UDE (i.e., IUDE or UDE-II), which secured the 1st rank in the CEC 2018 competition on constrained real parameter optimization. UDE-II was inspired by the following state-of-the-art DE variants - CoDE, JADE, SaDE, DE with ranking-based mutation operator, SHADE, and C2oDE. To design UDE-III, we extensively analyzed and targeted the weaknesses of UDE-II. Specifically, UDE-III uses three trial vector generation strategies - DE/rand/1, DE/current-to-rand/1, and DE/current-to-pbest/1. It is based on a dual population approach, and for each generation, it divides the current population into two sub-populations. The top sub-population employs all three trial vector generation strategies on each target vector, just like in CoDE. On the other hand, in the bottom sub-population, one trial vector generation strategy is implemented on each target vector. The bottom sub-population employs strategy adaptation, wherein the probability of the three trial vector generation strategies is adapted in every generation by learning from their experiences in generating promising solutions in the previous learning period. The mutation operation in UDE-III is based on ranking-based mutation. Further, it employs the parameter adaptation principle of SHADE. The constraint handling principle in UDE-III is based on a combination of the feasibility rule and epsilon-constraint handling technique as proposed in C2oDE. We observed that stagnation is a major weakness of UDE-II. To overcome this weakness, we took inspiration from the best-discarded vector selection (BDVS) strategy proposed in the literature and integrated a novel strategy in UDE-III to address stagnation. Additionally, UDE-III considers the size of two sub-populations to be a design element, whereas in UDE-II, the t

Eye tracking is a method of measuring and analyzing the movements of the eyes as they move and focus on different objects in the visual field. This technique has been used in a wide range of fields, including psychology, neuroscience and human-computer interaction. Eye tracking provides valuable insights into how individuals process visual information, including attentional biases, cognitive processing, and decision-making. Traditionally, eye tracking has relied on licensed software and specialized hardware, making it costly and less accessible for some researchers and applications. However, with recent technological advancements and by leveraging the capabilities of webcams, researchers, and practitioners can now perform eye-tracking experiments without the need for expensive equipment. By utilizing webcams, researchers can conduct eye-tracking experiments in a cost-effective manner, making the method more accessible to a broader range of researchers and practitioners.

Accurately identifying gait phases offers vital insights into medical diagnostics, requiring precise biomechanical assessment. Despite various machine learning (ML) methods, achieving high precision is challenging. This study uses ML techniques to classify the gait phases of 100 individuals (average age 41.91 ± 5.3 years). Classification algorithms considered in this work are: k-Nearest Neighbor (k-NN), Logistic Regression (LR), Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM), and Naive Bayesian (NB). The performance of these algorithms is evaluated using two training methods while classifying binary (stance/swing) and ternary (stance-I/stance-II/swing) subphases. In the first method, 80% of the data from binary or ternary phases is randomly selected for training and the rest for testing. In the second method, data is divided by participants, with 80% used for training and 20% for testing. The RF algorithm consistently outperforms others in both training methods, achieving 99.5% (first method) and 99.9% (second method) accuracy in binary classification and 99.4% (first method) and 99.5% (second method) in ternary classification. Despite the reduced performance while transitioning from binary to ternary classification, consistency is maintained for all ML algorithms. Moreover, the second training method is more effective for classifying binary and ternary gait phases. ©2024 IEEE.

Although concrete is one of the most common building materials used today, determining the precise concrete compressive strength is still difficult due to the extremely complicated interplay between its composition. The paper shows designing of M40 concrete and then finds the change in compressive strength of concrete on adding admixtures. First admixture used by us is, ground granulated base furnace. We replace cement with GGBS with 5, 20, and 35% of cement. We make 6 cubes sample of each case and then test 3 cubes sample of each case on 7 day and other 3 cubes samples on 28 days. Second admixture used by us is sugar. Here we didn’t replace cement with sugar but taken certain percentage of total weight of cement. We have taken.01,.05,.08, and.1% of weight of cement. In this also we had made 6 cube samples of each case and then test 3 cubes samples of each case for 7 days and remaining cubes are tested on 28 days. Finally, we compared normal concert compressive strength, concrete formed by using GGBS and then concrete made using sugar admixture. In order to determine the concrete workability and determine the impact of the admixture on the workability of the concrete, we again undertake slump tests in both circumstances. In between, we also discussed the problem of input accuracy and output relationship during the processing of data using machine learning techniques. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Real-time, interactive 4D traffic scene generation enables rapid digital twinning of traffic scenarios, improving management and decision-making in intelligent transportation systems. However, current text-to-video models, such as Sora, struggle to maintain the temporal coherence of traffic elements and interact with dynamic environments and users when generating 4D scenes. This article introduces a novel cloud-edge-terminal collaborative framework that leverages Artificial Intelligence-Generated Content (AIGC) in vehicular networks to tackle these challenges, ensuring long-term coherence and improved interactivity. The framework presents a comprehensive architecture for real-time interactive 4D scene generation, encompassing data collection, management, model pre-training, fine-tuning, and inference. We examine key design requirements and challenges, demonstrating that our microservice-based framework enables the system to generate and update 4D traffic scenes in real time, effectively responding to traffic data and user inputs. To the best of our knowledge, this is the first successful implementation of real-time, interactive 4D traffic scene generation. Performance evaluations show the superiority of our framework, powered by microservice-based code fine-tuning, over traditional frameworks. Finally, we discuss future research directions to enhance AIGC-driven 4D traffic scene generation. © 1986-2012 IEEE.
