Efficient cloud resource management is vital, as it ensures the accurate selection and allocation of resources to diverse workloads or applications. This entails real-time balancing of workload performance, compliance, and cost to achieve optimization. Since there are many cloud users involved in scheduling tasks, or cloudlets, the scheduling process becomes complex. It involves selecting appropriate data centers, servers (hosts), and virtual machines (VMs). There are several bioinspired algorithms that are effective and popular for solving the NP-complete problem of cloudlet scheduling. By using these algorithms, cloudlets can be efficiently allocated to achieve faster execution times, better resource utilization, and a shorter waiting time. This study presents a hybrid technique that combines the strengths of both ant colony optimization and locust-inspired algorithm (HACO-LA), which have been shown to outperform other bio-inspired algorithms in cloud computing environments. Implementing this technique will lead to a decrease in the average response time, while also increasing the utilization of VMs and servers. The method was evaluated using the Cloud Sim toolbox with authentic data. It was compared to the preexisting Artificial Bee Colony Optimization (ABC) algorithm and Particle Swarm Optimization (PSO) algorithm. The findings demonstrated that HACO-LA surpassed both methods, leading to notable enhancements in server utilization, increased reliability, and decreased average response time.

Low energy consumption vehicles such as Electric Motorcycles (EMs) are a very viable solution to reduce energy consumption in the transportation sector. Due to their low power and weight, EMs have high energy efficiency and are optimized for urban transit. In this context, it becomes necessary to develop systems prototypes for any type of Electric Vehicles (EVs). Therefore, the focus of this paper is the implementation of traction and charging systems for an EM. The traction system is composed by a DC motor and a power converter that operates the motor. The power converter control allows the motor to operate in different modes. Besides, the traction system's input is a hand accelerator/brake that can control the motor speed/torque. The charging system acts as an interface between the power grid and the motorcycle system. With this, the first stage of the charger is AC-DC rectification that, besides regulating the DC-link voltage, should also act as a Power Factor Corrector (PFC) and consume a sinusoidal current from the power grid. The charger should also ensure the battery's safety and offer the possibility of regulating the charging rate. This paper details the development of traction and charging systems from the presentation of topologies to the computational simulations, and respective experimental tests and validation.

Predicting traffic patterns is crucial for urban traffic management and planning, which predicts future traffic data based on current traffic conditions. To acquire better prediction accuracy, traffic flow forecasting requires complex dependencies in both temporal and spatial information. The spatial information is highly related to the traffic network, and how to effectively capture the relationships between graph nodes in the traffic network is crucial. To deal with this problem, we propose to utilize random walk embedding to capture the information transmission and correlations between nodes. Then, we combine random walk with transformer and propose random walk embedded spatial-temporal transformer (RW-STT) model to deal with the traffic flow forecasting problem. Experimental results on three traffic datasets demonstrate that RW-STT can capture more comprehensive correlations between spatial nodes and outperforms other baselines significantly.

Cross-modal person re-identification (Re-ID) compensates for the supervision of suspicious persons under dark conditions and has important significance in real life. Existing related studies based on triplet loss adopt either too strong or too weak constraints to aggregate features, so in order to further improve accurate person Re-ID, this paper proposes a weighted regular heterogeneous-center loss, which adopts a weighted approach to adaptively keep the centers of person features of different identities away from each other while pulling the centers of same identities of different modalities closer. Besides, this paper also proposes a network for adaptive extraction of local features, which adaptively extracts local features through an attention mechanism, and then employs a combination of global features and local features to effectively enhance the robustness of person features and improve the detection accuracy of person Re-ID. Experiments on two publicly available cross-modal person re-identification datasets SYSU-MM01 and RegDB in this paper demonstrate the effectiveness of the proposed method, which achieves comparable or leading detection results compared with current mainstream algorithms.

This abstract examines the role of mistake manipulation in asynchronous transfer mode (ATM) networks. Errors management is an error correction that ensures dependable fact transfers in computer networks, and that is especially essential in ATM networks that require the transfer of large quantities of records at high speeds. To better understand the role of error control in ATM networks, this abstract will pay attention to two primary areas: blunder correction protocols and error control mechanisms. Mistake correction protocols assist in sure the accuracy of facts by detecting and correcting errors. Blunder control mechanisms are used to reduce or cast off error propagation, and this is done via the usage of float management, retransmission, and buffer management strategies. Via a theoretical and empirical examination of error control in ATM networks, this abstract will offer a better understanding of the role that blunder manipulation plays in ensuring dependable and efficient fact transfers.

With the explosive growth of various devices, terminals and services, communication networks are in urgent need of security, reliability, flexible access and real-time interaction. Meanwhile, the power communication network extends to the low-voltage side, which needs to analyze a lot of interactive information to realize the perception, prediction and control of the system operation state. The traditional network model has certain deficiencies in taking into account the economy, efficiency and performance. This paper studies and analyzes the application of FlexE (Flexible Ethernet) technology in new type power systems to adapt to services with different granularities and performance requirements, realize unified access of various services, and promote the deep integration and adaptation of FlexE technology to the new type of power system.
