Patients' data is stored in Electronic Health Records (EHRs) for confidentiality purposes. However, the insecure networks of hospitals and clinics puts patient information at risk. To address this ethical issue, secure communication is crucial. The Digital Imaging and Communications in Medicine (DICOM) standard governs the transmission of EHRs to maintain data integrity and confidentiality. This paper combines cryptography and steganography techniques to transmit medical information and images across hospital networks, securely. The introduced framework comprises encryption of patients' data using DNA-based Advanced Encryption Standard (AES), hiding the information within images using Least Significant Bit (LSB) embedding, compressing the stego images using Discrete Wavelet Transform (DWT), and reversal of the process at the receiver end. Simulation experiments demonstrate that this framework comprising both encryption and steganography outperforms existing methods in securing the medical data.

In this paper, we consider the sum rate maximization problem in a downlink unmanned aerial vehicles (UAV) assisted heterogeneous networks (HetNets) to mitigate existing interference. We propose to manage the interference by jointly optimizing the position of the UAV as well as power allocation. The proposed optimization problem is non-convex due to the non-linearity in the objective function and the constraints. We propose a near-optimal solution that breaks down the problem into two consecutive problems. First, we proposed a reinforcement learning-based technique to solve the UAV positioning problem. Then, a particle swarm optimization (PSO) based technique is applied to the power allocation problem. Simulation results demonstrate the efficiency of the proposed algorithm. © 2022 IEEE.

With the rapid growth of dynamic vision sensor (DVS) data, constructing a low-energy, efficient data retrieval system has become an urgent task. Hash learning is one of the most important retrieval technologies which can keep the distance between hash codes consistent with the distance between DVS data. As spiking neural networks (SNNs) can encode information through spikes, they demonstrate great potential in promoting energy efficiency. Based on the binary characteristics of SNNs, we first propose a novel supervised hashing method named Spikinghash with a hierarchical lightweight structure. Spiking WaveMixer (SWM) is deployed in shallow layers, utilizing a multilevel 3D discrete wavelet transform (3D-DWT) to decouple spatiotemporal features into various low-frequency and high-frequency components, and then employing efficient spectral feature fusion. SWM can effectively capture the temporal dependencies and local spatial features. Spiking Self-Attention (SSA) is deployed in deeper layers to further extract global spatiotemporal information. We also design a hash layer utilizing binary characteristic of SNNs, which integrates information over multiple time steps to generate final hash codes. Furthermore, we propose a new dynamic soft similarity loss for SNNs, which utilizes membrane potentials to construct a learnable similarity matrix as soft labels to fully capture the similarity differences between classes and compensate information loss in SNNs, thereby improving retrieval performance. Experiments on multiple datasets demonstrate that Spikinghash can achieve state-of-the-art results with low energy consumption and fewer parameters. Copyright © 2025, The Authors.

Protests against racial injustice have been increasing in the United States. Universities often rapidly respond to acts of injustice through public statements about their position to uphold the equality of all people. To gauge the desires and concerns around discussing events causing social unrest in engineering classrooms specifically, the engineering education faculty chair of a large university conducted discussions with both students and faculty regarding its place in their classrooms. This paper describes the emerging themes from survey responses using coding and grounded theory. Reactions from students and faculty were decidedly different. Most students stressed the importance of discussing such topics in class with their engineering faculty, while most faculty emphasized their concerns with doing so due to their lack of training to effectively handle such topics. This paper describes the evaluation of student and faculty responses and its implications for supporting diversity and inclusion in the engineering classroom. © American Society for engineering Education, 2021

WSNs are applied in many disciplines where certain conditions require the ability to adapt to network sink mobility and changes in the dynamics of the area coverage. To meet these needs, it is necessary to develop integrated systems where the “‘terrestrial’ systems and the Unmanned Aerial Vehicles (UAVs)” collect data from sensors efficiently. Planning of UAV trajectories is another challenging issue if many WSN nodes are randomly deployed. This challenge has a big impact on the overall effectiveness of the system. This paper presents a novel approach for reducing the traveled distance of unscrewed aerial vehicles (UAVs) to improve the data collection efficiency in WSNs with poor node density. Yet the method that has been developed is aimed at increasing “the efficiency and efficacy of data collection… with the assistance of Unmanned Aerial Vehicles (UAVs)” which means this work reveals practical application solutions.

Sixth generation (6G) cellular communications are expected to support enhanced wireless localization capabilities. The widespread deployment of large arrays and high-frequency bandwidths give rise to new considerations for localization applications. Emerging antenna architectures, such as dynamic metasurface antennas (DMAs), are expected to be frequently utilized thanks to the achievable high angular resolution and low hardware complexity. Further, wireless localization is likely to take place in the radiating near-field (Fresnel) region, which provides new degrees of freedom, because of the adoption of arrays with large apertures. While current studies mostly focus on the use of costly fully-digital antenna arrays, in this paper we investigate how DMAs can be applied for near-field localization of a single user. We use a direct positioning estimation method based on curvature-of-Arrival of the impinging wavefront to obtain the user location, and characterize the effects of DMA tuning on the estimation accuracy. Next, we propose an algorithm for configuring the DMA to optimize near-field localization, by first tuning the adjustable DMA coefficients to minimize the estimation error using postulated knowledge of the actual user position. Finally, we propose a sub-optimal iterative algorithm that does not rely on such knowledge. Simulation results show that the DMA-based near-field localization accuracy could approach that of fully-digital arrays at lower cost. © 2023 IEEE.

Accidents are less likely to happen when employing self-driving cars. However, automotive applications require more time and cost, simulation tool is a much more cost-effective and time-saving option. To reduce driver fatigue and ensure pedestrian safety, a vehicle's cruise control depends heavily on control engineering. To aid in vehicle safety, the automotive manufacturing sector is forecast to develop a range of cruise control strategies. Because of elevated traffic on the roads, there is a significant need for the development of Automatic Cruise Control (ACC). The feedback control system's architecture is essential for the achievement of ACC. This paper presents the controller tuning techniques for designing an ACC system. Researchers frequently utilized Ziegler-Nichols techniques in tuning Proportional Integral Derivative (PID) controllers. These tuning processes may be time-consuming and difficult for a complex nonlinear structure. This paper shows how to employ metaheuristic methodologies to quickly fine-tune the PID controller's parameter. The first stage is to construct a mathematical model of the cruise control system on the vehicle. The PID settings are then optimized using the firefly and cuckoo search optimized algorithm. Both metaheuristic PID controllers achieve the necessary vehicle velocity, according to simulations. From the results, it also inferred that the designed controller helps the system to attain the required velocity smoothly, with negligible overshoot and minimal rise time. © 2022 IEEE.
