Device-to-device connection is a captivating new approach that holds great potential for the next generation of mobile networks, among others 5G and beyond. One of the reasons for this is that it has the capacity to boost system throughput, reduce the burden on the network core, and enhance spectral efficiency. Therefore, in order to make the most of these advantages, it is of the utmost importance to enhance the allocation of resources and power in order to reduce the amount of interference caused by co-channels. This paper proposes utilizing a based simulated annealing (SAA) technique to enhance combined radio spectrum and energy allocation. The SAA is made up of a phase that involves heating, which is then followed by slow and steady cooling. This is a method that is very often used in the field of metallurgy. Doing so results in an ordered and therefore stronger metal with more flexibility and less energy. The simulation outcomes show that the proposed approach surpasses both the random solution and Genetic approach (GA) in terms of time to stabilize to an optimal solution, throughput, and obtaining a feasible solution. © 2024 IEEE.

This letter addresses the problem of flocking motion in the context of port-Hamiltonian systems. The port-Hamiltonian framework offers advantages in modeling networks, dissipation, and heterogeneous agents. In this regard, designing flocking controllers in port-Hamiltonian form significantly increases their practical applications. Additionally, event-triggered control has proven effective in reducing bandwidth consumption. However, challenges remain in combining flocking requirements with energy-dissipating terms. Therefore, we propose a novel event-triggered flocking controller suitable for port-Hamiltonian systems. The method is validated through numerical simulations of a group of hexarotors. © 2017 IEEE.

Recently, learning-based methods have made significant progress for image specular highlight removal. However, many of these approaches treat all the image pixels uniformly, overlooking the negative impact of invalid pixels on feature reconstruction. This oversight often leads to undesirable outcomes, such as color distortion or residual highlights. In this paper, we propose a novel image specular highlight removal network called HighlightRNet, which utilizes valid pixels as references to reconstruct the highlight-free image. To achieve this, we introduce a context-aware fusion block (CFBlock) that aggregates information in four directions, effectively capturing global contextual information. Additionally, we introduce a location-aware feature transformation module (LFTModule) to adaptively learn the valid pixels for feature reconstruction, thereby avoiding information errors caused by invalid pixels. With these modules, our method can produce high-quality highlight-free results without color distortion and highlight residual. Furthermore, we develop a multiple light image-capturing system to construct a large-scale highlight dataset called NSH, which exhibits minimal misalignment in image pairs and minimal brightness variation in non-highlight regions. Experimental results on various datasets demonstrate the superiority of our method over state-of-the-art methods, both qualitatively and quantitatively. © 2024 ACM.

In the original publication, the author has found few errors in the figures 2, 4, 11 and 12 which significantly impact both the paper's quality and the reputation of the journal. These issues undermine the clarity of the methodology and the novelty of the research. 1. Each column represents a different case in the experiment, corresponding to the number of UAVs in both the obstacle-free and obstacle areas. However, in Fig. 2, the first row contains identical subfigures across all columns, while the subfigures in the remaining rows are identical to each other The incorrect Fig. 2 appears as below: (Figure presented.) However the corrected Fig. 2 should appear as below. (Figure presented.) 2. In Fig. 4, every row showcase the average QoF for the testing scenarios (obstacle-free and obstacle area).

Today, much attention is paid to the engineering of dependable and resilient intelligent systems and models. This direction includes multi-attribute group decision making (MAGDM) models and systems in emergency situations. As a rule, they are characterized by insufficient objective data and lack of response time to the solution of the problem. We consider in this direction a new MAGDM of facilities locations selection problem (FLSP) based on the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach. Expert's evaluations of each candidate of humanitarian aid distribution center (HADC) relative to uncertain attributes in q-rung orthopair fuzzy numbers (q-ROFNs) are presented. The offered model is examined with a numerical example. © 2023 IEEE.

Today, much attention is paid to the engineering of dependable and resilient intelligent systems and models. This direction includes multi-attribute decision-making (MADM) models and systems in emergency situations. A new interactive MADM approach based on evidence theory and fuzzy discrimination analysis is developed. MADM's utilities in the discrimination q-rung orthopair fuzzy values in the Dempster-Shaper's believe structure environment are transformed. New aggregation operators - extensions of Dempster's extremal expectations under discrimination q-rung orthopair fuzzy information are constructed. MADM's alternatives by new constructed operators are ranked. For the illustration of obtained results, a numerical example is created from Emergency Psychiatric Diagnostics (EPD). © 2023 IEEE.

We address the problem of safely coordinating a network of Connected and Automated Vehicles (CAVs) in conflict areas of a traffic network. Such problems can be solved through a combination of tractable optimal control problems and Control Barrier Functions (CBFs) that guarantee the satisfaction of all constraints. These solutions can be reduced to a sequence of Quadratic Programs (QPs) which are efficiently solved online over discrete time steps. However, guaranteeing the feasibility of the CBF-based QP method within each discretized time interval requires the careful selection of time steps which need to be sufficiently small. This creates computational requirements and communication rates between agents which may limit the controller's application to real CAVs. We tackle this limitation by adopting an event-triggered control approach for CAVs such that the next QP is triggered by properly defined events with a safety guarantee. We present a laboratory-scale test bed developed to emulate merging roadways using mobile robots as CAVs. We present results to demonstrate how the event-triggered scheme is computationally efficient and can handle measurement uncertainties and noise compared to time-driven control while guaranteeing safety. © 2023 IEEE.
