Abstract

This paper presents a LiDAR-based end-to-end autonomous driving method with Vehicle-to-Everything (V2X) communication integration, termed V2X-Lead, to address the challenges of navigating unregulated urban scenarios under mixed-autonomy traffic conditions. The proposed method aims to handle imperfect partial observations by fusing the onboard LiDAR sensor and V2X communication data. A model-free and off-policy deep reinforcement learning (DRL) algorithm is employed to train the driving agent, which incorporates a carefully designed reward function and multi-task learning technique to enhance generalization across diverse driving tasks and scenarios. Experimental results demonstrate the effectiveness of the proposed approach in improving safety and efficiency in the task of traversing unsignalized intersections in mixed-autonomy traffic, and its generalizability to previously unseen scenarios, such as roundabouts. The integration of V2X communication offers a significant data source for autonomous vehicles (AVs) to perceive their surroundings beyond onboard sensors, resulting in a more accurate and comprehensive perception of the driving environment and more safe and robust driving behavior., Comment: To be published in IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2023

Abstract

Current connected vehicle applications, such as platooning require heavy‐load computing capability. Although mobile edge computing (MEC) servers connected to the roadside intelligence facility can assist such separable applications from vehicles, it is a challenge to coordinate the allocation of subtasks among vehicles and MEC servers on the premise of ensuring communication quality. Therefore, an offloading algorithm is proposed based on a double deep Q‐network to solve the placement of subtasks for vehicle to infrastructure and vehicle to vehicle cases. This algorithm considers the randomness of task generation and is model‐free. The MEC server can assist the vehicle in training the neural network and storing relevant state transitions. To improve the performance of the algorithm, the decaying ε−$\varepsilon - $greedy policy is incorporated for faster convergence. The simulation results showed that this algorithm performed well in reducing the dropped subtask rate, average time delay, and total energy consumption. [ABSTRACT FROM AUTHOR]

50. The effect of bridging groups on the charge transport properties of benzothiophene-substituted anthracenes.

Abstract

A series of novel asymmetric anthracene derivatives, namely 5-BTA, 5-BTVA, and 5-BTEA, consisting of a single bond, vinyl, and ethynyl bridged benzothiophene and anthracene core were synthesized. Single crystal structure analysis reveals that all three compounds adopt head–head bilayer stacking along the molecular long axis and herringbone packing along the short axis. The vinyl-bridged 5-BTVA exhibits stronger intra-layer intermolecular interactions, which shows characteristic regular shape with sharp edges and have a suitable thickness (<50 nm) to construct transistors, obtaining a 5–10 fold hole mobility over 10 cm2 V−1 s−1 than 5-BTA and 5-BTEA. The better energy level alignment of 5-BTVA to Au electrodes also induces a lower contact resistance. The temperature-dependent device physics studies reveal the low trap density and low activation energy characteristics of 5-BTVA. [ABSTRACT FROM AUTHOR]
