The Internet of Things (IoT) is a new heterogeneous system integrated by various end-users with different technologies. However, the limiting factor is bandwidth in the IoT due to exploding the end-users and the network bandwidth requirement. A novel IoT model, which integrates the Power Line Carrier (PLC) and the Wireless Network (WN), is proposed to solve the bandwidth problem from the architecture, especially in the areas lacking network facilities. In addition, we exploit an effective virtual layer (EVL) which allows the different end-users access to the model seamlessly. Then, the attractor selection algorithm based on Markov chain (ASMA) is employed to select an optimal path among the PLC or the WN. Simulation results demonstrate that the proposed model has the smaller delay than other algorithms and makes the model more stable. © 2018 IEEE.

Recently, Low Earth Orbit (LEO) satellite constellations with low-latency and high-bandwidth attract extensive research. However, most available studies focused on the field of satellite network routing algorithms, ignoring the impact of topology on the efficiency of inter-satellite networking and the quality of inter-satellite communication. In this paper, we propose a satellite network topology design method based on deep reinforcement learning (DRL), with the goal of reducing the latency of the entire satellite network. To achieve this goal, we first model the satellite network communication scene and formulate the topology optimization problem as a Markov decision process (MDP). Then, we further propose the idea of backbone-point satellites and use DRL to optimize the topology structure. Finally, we conduct extensive experiments on different performances of satellite topology, and we conclude that the network topology constructed in this way can provide lower latency communications than the motif and +Grid topologies, optimized by 8.48% and 42.86% respectively. © 2023 SPIE.

With the continued development of accelerated urbanization and the rapid growth of urban population, public transport priority is not only an effective measure to ease urban traffic congestion, but also a requirement of improving the urban living environment and promoting sustainable urban development. How to increase the attractiveness and service level of public transport becomes an important issue. In this paper, an investigation is done to analyze the influencing factors of public transport attractiveness. A binary Logit model is established to evaluate the importance level of the factors affecting their public transport choice under conditions of different travel distances, which can provide basis for relevant government departments to enhance or improve the service quality of public transport. The results show that either the influence factors of trips with different distances (long distance, middle distance, and short distance) or the impact extent are not the same. © 2014 American Society of Civil Engineers.

Considering nonlinear behaviors and environmental disturbance of the boiler pressure control system, a linear interpolation fuzzy controller is developed. First, according to the conventional discrete fuzzy control principle, a discrete fuzzy controller for the system is designed and a 2-D fuzzy control lookup table is deduced. Then, to overcome the conventional fuzzy controller's disadvantage of lower precision caused by discretization, a bilinear interpolation 2-D table lookup method is used to replace the exact lookup method, with which continuous output can be obtained from the discrete control table. Finally, based on the existed computer control system and boiler system hardware configuration, hard-in-loop real-time simulation system is established in Matlab/RTWT. Lots of experiments are carried out. And the results prove that better control performance can be achieved with the proposed control scheme. © 2013 IFAC.

Cognitive radio (CR) network is the promised paradigm to resolve the spectrum shortage and to enable the cooperation in heterogeneous wireless networks in 5G and beyond. CR mainly relays on Spectrum Sensing (SS) strategy by which the vacant spectrum portion is identified. Therefore, the sensing mechanism should be accurate as much as possible, as long as the subsequent cognition steps are mainly depended on it. In this paper, an efficient and blind SS algorithm called Deep Learning Based Spectrum Sensing (DBSS) is proposed. This algorithm utilizes the deep learning approach in SS by using Convolutional Neural Network (CNN) as a detector instead of energy thresholding. In this algorithm, the computed energies of the received samples are used as dataset to feed the optimized CNN model in both training and testing phases. The proposed algorithm is simulated by MATLAB, the simulation scenarios divided into: CNN optimization (training) and SS. The last scenario shows the detection ability of the proposed algorithm for PU under noisy environment. The simulation results show that the proposed algorithm reached high detection probability (Pd) with low sensing errors at low SNR. In addition, high recognition ability to identifying Primary User (PU) signal form noise only signal is achieved as well. Finally, the proposed algorithm is validated with respect to real spectrum data that supported by SDR in an experimental signal transmission and reception scenario. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Case study on combination of fluorescent materials for white LED to obtain high color rendering indexes

Journal of Light and Visual Environment 2006年第1期30卷 39-45页

This letter reports on white-LED with high color rendering property. We realized the white-LED whose average Color Rendering Index (CRI) is as high as 94.2 by applying the commercial Red, Yellow, Green and Blue phosphors to near ultraviolet-LED. So far as we know, this value is the highest ever attained in white-LED around the color temperature of 5500[K]. In order to realize the good Ra (average CRI), we made a CRI simulator and simulated the spectrum distribution of white-LED with good Ra. The spectrum distribution obtained by this simulation was proved to be very useful as a landmark for realizing a prototype white-LED with good Ra.

Visible light positioning (VLP) has attracted considerable interest due to its high accuracy and low cost. However, VLP typically requires several light emitting diodes (LEDs) for positioning, which may lead to positioning failure in sparse LED layout or parts of the links are blocked. To address this challenge, we propose a novel graph optimization-based localization algorithm by fusing VLP and visual odometry (VO), termed GO-VLO. In the considered model, a few LEDs are deployed on the ceiling and broadcast positioning information, while a receiver equipped with a camera conducts GO-VLO to achieve precise positioning with limited LEDs. GO-VLO consists of a front end to process positioning information and a back end to further optimize the positioning results. In particular, VLP and VO are first used separately at the front end, thus obtaining two respective positioning results. Then, a visible-light visual odometry fusion mechanism is proposed to fuse the positioning results of VLP and VO preliminarily. To strengthen the constraints between frames and prevent location failure when VLP is unavailable, a novel graph optimization framework is further proposed in the back end, which notably takes the covisible feature points of two successive frames into consideration. Experimental results show that our proposed method attains a positioning accuracy of 4.93 cm in two dimension and 6.20 cm in three dimension under dense LED layout. © 2023 IEEE.

In recent years, lectures using electronic devices have been tried in various educational institutions. Using these electronic devices is effective as a means of active participation in lectures for students. The Wii remote is one of these devices. In this paper, we propose the "Eeclass," an interactive lecture support system which uses the Wii Remote. One feature of this system is that students can write in the air using Wii - remotes instead of a blackboard. Implemented functions are as follows: (1) Automatic attendance confirmation, (2) Additional writing on electronic blackboard using an electronic pen device, (3) Automatic counting of a show of hands, (4) Voting opinions, and (5) Writing letter in the air. From the experimental result for 1077 Japanese characters using this handwriting function, we confirmed that the recognition accuracy was 78.5% for the first test and for the 15th was 98.8%.
