Digital twin based intelligent urban traffic forecasting and guidance strategy by Xiwen LIAO, Supeng LENG, Yujun MING, Tianyang LI

“…As the technology of ubiquitous Internet of things and artificial intelligence improves by leaps and bounds, the transportation system revolution is flourishing and bringing new opportunities and challenges.Considering the defect in the existing navigation system, and the neglect of the temporal and spatial characteristics of traffic flow, the macro traffic network and micro vehicle network were modeled and their coupling relationship was mined.Then, a digital twin based urban traffic forecasting and guidance method was proposed to alleviate the problem of traffic congestion.The spatial-temporal traffic flow information was predicted through the diffusion convolution recurrent neural network, which was explicitly applied to the vehicle path planning decision.On this basis, a spatial-temporal collaborative deep reinforcement learning method was proposed to implement the future-oriented collaborative path planning of vehicles.It also guided the underlying vehicle twins to select the optimal strategy for the real world.With SUMO for simulation verification, the experimental results show that the proposed method is significantly better than the existing algorithms in improving the travel completion ratio and congestion relief, and can improve the efficiency of urban traffic travel.…”

LQG control-aware resource scheduling method for IEEE 802.11ax networks by Meng ZHENG, Lei ZHANG, Wei LIANG

“…Due to the advantages in low cost, ease of maintenance and license-exempt spectrum, etc, IEEE 802.11ax is widely adopted in industrial control applications.For a wireless networked control system based on IEEE 802.11ax, a control-aware resource scheduling method was proposed to support the wireless high-speed control of multiple control systems.Firstly, considering the packet dropout problem of sensing data in IEEE 802.11ax, the optimal state estimator and the linear quadratic Gaussian (LQG) control of the studied control system were given.Secondly, the dependency between the LQG performance and the transmission reliability of IEEE 802.11ax was analyzed, the expected LQG performance minimization problem of resource scheduling was formulated, and further, an LQG control-aware resource scheduling (LCARS) method was proposed.Finally, the effectiveness of the LCARS method was demonstrated via extensive simulations.LCARS can be applied to smart factory applications including navigation of automated guided vehicles, remote control of robots and so on.…”

The Edible I in Kim Fu’s For Today I Am a Boy by Veronica Austen

“…In this novel’s portrayal of Peter (see note 3), the trans woman protagonist, images of food and acts of eating (or the denial of these acts) are deployed as a meditation on the navigation of body, hence of self. This paper positions the act of eating as representing more than just a physical, biological process, but rather a placing of people in relationship with the edible matter and all the conditions of its production, including its socio-cultural/familial meanings. …”

Trajectory planning of UUV-assisted UWOC systems based on DQN by Jiawei HU, Xiaoqian LIU, Xinke TANG, Yuhan DONG

“…As a key submarine-based communication platform, unmanned underwater vehicle (UUV) can facilitate underwater wireless optical communication (UWOC).However, fluctuating characteristics of water body, different water qualities, multi-user access present challenges to UUV-assisted UWOC systems, which could be alleviated by an appropriate path planning to maximize the system and each user performance.Deep reinforcement learning (DRL) technology was applied in the path planning of autonomous vehicles, a trajectory planning scheme for UUV-assisted UWOC systems was proposed.The UUV automatically decides the navigation direction through deep Q-network (DQN) method, thereby improving the communication capacity of the system and each user.The impact of distinct water qualities on the capacity enhancement was also investigated.Simulation results suggest that the outputted strategy of DQN can improve the link capacity of the system and each user.This capacity improvement in clear seawater is better than that in pure seawater but lower than that in coastal water.…”
