Forest fires are a huge ecological hazard, and smoke is an early characteristic of forest fires. Smoke present only in tiny region images that captured the stages occurrence or when far from camera. Furthermore, dispersal uneven, background environment complicated changing, thereby leading to inconspicuous pixel-based features complicate detection. In this paper, we propose detection method called multioriented based on value conversion-attention mechanism module Mixed-NMS (MVMNet). First,...
The efficiency of the classic alternating direction method multipliers has been exhibited by various applications for large-scale separable optimization problems, both convex objective functions and nonconvex functions. While there are a lot convergence analysis case, case is still an open problem research this in its infancy. In paper, we give partial answer on problem. Specially, under assumption that associated function satisfies Kurdyka–Łojasiewicz inequality, prove iterative sequence...
Smart city (SC) technologies can provide appropriate services according to citizens’ demands. One of the key enablers in a SC is Internet Things (IoT) technology, which enables massive number devices connect with each other.

Moreover, will produce large amounts data, and efficiently analyzing data for intelligent services. In this paper, we propose novel artificial...
By offloading tasks from the mobile device (MD) to its nearby deployed access points (APs), each of which is connected one server for task processing, computation can strike a balance between MD's execution delay and energy consumption in edge computing (MEC) systems. Considering communication dynamics MEC systems, we aim design online mechanisms this paper minimize time average expected under constraint consumption. Firstly, with known current channel gains MD APs as well available...
Mobile edge computing (MEC) is considered a novel paradigm for computation-intensive and delay-sensitive tasks in fifth generation (5G) networks beyond. However, its uncertainty, referred to as dynamic randomness, from the mobile device, wireless channel, network sides, results high-dimensional, nonconvex, nonlinear, NP-hard optimization problems. Thanks evolved reinforcement learning (RL), upon iteratively interacting with random environment, trained agent can intelligently obtain optimal...

The unmanned aerial vehicle (UAV) network that is convinced as a significant component of 5G and emerging 6G wireless networks desired to accommodate multiple types service requirements simultaneously. However, how converge different services onto common UAV without deploying an individual solution for each type challenging. We tackle this challenge in paper through slicing the network, i.e., creating logical customized specific requirements. To end, we formulate problem sequential decision...
African swine fever virus, a large and complex icosahedral DNA causes deadly infection in domestic pigs. In addition to Africa Europe, countries Asia, including China, Vietnam, Mongolia, were negatively affected by the hazards posed ASFV outbreaks 2018 2019, at which time more than 30 million pigs culled. Until now, there has been no vaccine for protection against or effective treatments cure ASF. Here, we solved high-resolution crystal structure of pS273R protease. The protease two-domain...
Various datacenter network (DCN) load balancing schemes have been proposed in the past decade. Unfortunately, most of these solutions designed for lossy DCNs do not work well Priority Flow Control (PFC) enabled lossless DCNs, primarily due to reason that individual congestion signals used solutions, e.g., link load, queue length, Round Trip Time (RTT) and Explicit Congestion Notification (ECN), may be able correctly or timely reflect hop-by-hop PFC pausing. This paper first reveals above...
By migrating baseband processing functionalities into a centralized cloud-based unit (BBU) pool, cloud radio access network (C-RAN) facilitates cooperative transmission among remote heads (RRHs) and enables flexible computation provisioning in the BBU pool. In C-RAN, due to high amount of data transfer from pool RRHs through fronthauls, limited fronthaul capacity becomes key factor when designing schemes RRHs. Meanwhile, as computational resources are provisioned mobile users (MUs) for form...

Hence, we jointly optimize offloading scheduling minimize average delay in RAN, followed by an effective recursive algorithm. Through application extensions numerical evaluations,...
Through the allocation of multi-antenna time blocks to spacecrafts, data relay satellite network (DRSN) is capable providing within their visible intervals (i.e., windows). During process, generated hybrid tasks incorporate common tasks, emergency and temporary tasks. However, higher priority unpredicted tasks) unpredictably preempt antenna resources, thereby resulting in more unsuccessful relay. It is, therefore, nontrivial investigate dynamic task scheduling problem with windows for DRSN...
By exploiting the computing power and local data of distributed clients, federated learning (FL) features ubiquitous properties such as reduction communication overhead preserving privacy. In each round FL, clients update models based on their own upload updates via wireless channels. However, latency caused by hundreds to thousands rounds remains a bottleneck in FL. To minimize training latency, this work provides multi-armed bandit-based framework for online client scheduling (CS) FL...

Multicast is an efficient means of transmitting the same content to multiple receivers while minimizing network resource usage. Applications that can benefit from multicast such as multimedia streaming and download, are now being deployed over 3G wireless data networks. Existing schemes transmit at a fixed rate accommodate farthest located users in cell. However, belonging group have widely different channel conditions. Thus existing too conservative by limiting throughput close base...
