A novel technique that manipulates tiny objects using electrostatic forces is proposed. This technique, which has grid-structure electrodes, potentially can drive multiple objects individually. One of the possible applications is precise sorting of small plastic pieces by materials or colors. The dielectrophoretic force that is generated by concentrated electric field is mainly utilized in this technique. In this study, the effect of a protrusion attached at the cross-point of the grid was investigated using a single-cross device which is a basic structure of this technique. A glass sphere with approximately 1.2 mm diameter was used as a model for target objects. The driving force exerted on the target was determined with high-speed photography of the trajectories, along with numerical simulation. It was elucidated that the electric field concentrated by the protrusion enhanced the forces directing to the cross point. At the same time, the comparison with the simulation of the dielectrophoretic force and the calculation of the field strength suggested that a little amount of charge generated by discharge affected the driving force. Moreover, the transfer of the glass sphere between two cross-points with the interval of 2 mm in approximately 300 ms was successful. © 2024 The Institute of electrical Engineers of Japan.

The reconfigurable intelligent surface (RIS) steering reflective beam directions toward a target mobile user equipment (UE) has been a promising technology for coverage enhancement and physical-layer (PHY) security to avoid signal eavesdroppers and jammers. However, tracking and predicting the moving trajectory of UE demand significant computing burdens unaffordable to the RIS. Performing beam steering computations on the radio access network (RAN) intelligent controller in the open RAN (O-RAN) architecture therefore emerges as a revolutionary paradigm. In this paper, we propose a PHY-secured beam steering design based on a pre-processing-based Kalman filter algorithm. Through a pre-processing phase to derive the radiation feature, the proposed design accurately tracks the position of the mobile UE and quickly recovers the position search while position tracking fails. Through practical field-try experiments, we justify the capability of O-RAN RIC-empowered RIS for PHY security. © 2013 IEEE.

This work presents the architecture and development of the Serious Game (SG) Memô which is aimed at exercising the Short-Term Memory (STM) of children with Autism Spectrum Disorder (ASD). This serious game proposes an individualized functional approach through Dynamic Difficulty Adjustment (DDA), which considers the performance, the expressed facial emotions, and the level of eye attention during child performance. In addition, it is used to recording the presence of hand and eye stereotypies. The SG is developed in Unity 3D, uses MediaPipe to determine the points of the hands, and is executed by our Socially Assistive Robot (SAR), termed Mobile Autonomous Robot for Interaction with Autistics and Trisomy 21 (MARIA T21). We believe that the creation of SGs to assist in the cognitive development of children with ASD and explore the detection of other stereotyped movements, associating them with a communicative and emotional proposal, is feasible. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Deep Learning-Based Joint Channel Equalization and Symbol Detection for Air-Water Optoacoustic Communications

引用

IEEE Transactions on Cognitive Communications and Networking 2024年第3期11卷 1482-1492页

The optoacoustic effect is triggered by directing an optical signal in the air (using laser) to the surface of water, leading to the generation of a corresponding acoustic signal inside the water. Careful modulation of the laser signal would enable an innovative method for direct communication in air-water cross-medium scenarios experienced in many civil and military applications. In order to achieve a high data rate, a multilevel amplitude modulation scheme can be used to generate different acoustic signals to transmit multiple symbols. However, accurately demodulating these acoustic signals can be challenging due to multipath propagation within the harsh underwater environment, inducing inter-symbol interferences. This paper proposes a deep learning-based demodulation technique that uses a U-Net for signal equalization and a Residual Neural Network for symbol detection. In addition, fine-tuning at the receiver side is also considered to increase the demodulation robustness. The proposed deep learning model has been trained with our laboratory constructed dataset containing eight levels of optoacoustic signals captured from three different underwater positions. The model is validated using two datasets containing severe interference due to multipath-generated echoes and reverberations. The results show that our demodulation model achieves 96.6% and 91.7% accuracy for the two datasets, respectively, which significantly surpasses the 72.9% and 65.30% accuracy achieved by the conventional peak detection-based technique. © 2015 IEEE.

Elliptic curve cryptography (ECC) is an important building block for providing us with digital security nowadays and likely also in the future. Being able to compute the elliptic curve scalar multiplication (ECSM) fast would make the realtime complex cryptosystem more practical to be used in our lives. To meet those needs, we propose minor optimizations to Lookup Table Modular Reduction (LUTMR) to further reduce the modular multiplication latency. Then, we propose the ECSM accelerator that builds on a 5-stage modular multiplier based on the LUTMR technique together with a tight schedule for computing the Add/Double Mongomery ladder. Our architecture works on any Weierstrass curve, is constant-time, and is protected from simple power analysis (SPA). We demonstrate its performance by implementing the accelerator on Virtex 7 (Virtex Ultrascale+) FPGA for five curves which are Secp256k1, NIST-P256, BN254, NIST-P381, and BLS12-381. The latency for computing ECSM are 53.3, 52.6, 53.2, 88.1, and 71.8 μs (27.1, 27.8, 29.2, 44.5, and 40.8 μs) respectively. These are the lowest ever reported latency among the state-of-the-art architecture while also lowest in the normalized area-time criteria among the generic architecture. © 2024 IEEE.

The quantity of medical image data accessible for analysis is increasing because of advancements in telehealth services. Therefore, effective cryptographic solutions must be developed to prevent data manipulation by unauthorized users in insecure networks. This paper focuses on developing a lightweight symmetric cryptosystem algorithm with decreasing memory and power consumption at high speed for standard and medical images based on 3D intertwining logistic map-cosine (ILM-cosine), which is a powerful chaotic system in contemporary cryptography. The motivation of this paper is to reduce the memory space required for storing program data while minimizing execution time for lower implementation complexity in telehealth applications. Our proposed scheme consists of five main steps: ILM-cosine map key generation with histogram normalization, row rotation, column rotation, and exclusive-OR (XOR) logic operation. Various normal and medical images were used as samples for the simulation. The results showed that cipher images have good visual quality, high information entropy, large key space, and low computational complexity. © 2023 Copyright for this paper by its authors.

Recently, legged robots have attracted considerable attention as highly mobile rovers for planetary exploration. However, the surfaces of celestial bodies such as Mars and the Moon are primarily loose, causing slippage due to surface deformation from the rover's leg movements. To mitigate this, a walking method aimed at preventing slippage was proposed. In this walking method, the bearing capacity is increased by imparting vibration from the rover's leg to the loose soil on the ground. This walking method improved the mobility performance of the legged rover. It is crucial to investigate the increase in bearing capacity by imparting vibration in a realistic space environment to validate the effectiveness of the proposed method. This study examines the change in bearing capacity due to vibration under low atmospheric pressure, a condition found on Mars and the Moon. This condition affects the characteristics of ground sand due to decreased air resistance. Our findings provide valuable insights into using vibration in planetary exploration to enhance the performance of legged rovers. The experimental results indicate that the bearing capacity under low atmospheric pressure is nearly identical to that under standard atmospheric pressure, suggesting that atmospheric pressure conditions have minimal impact on the bearing capacity when vibration is applied. © 2024 International Society for Terrain-Vehicle systems.
