Narrow space manipulations are crucial for equipment maintenance, as they eliminate the need for disassembly, thus reducing costs and increasing efficiency. Cable-driven flexible robots possess exceptional capabilities in maneuvering through narrow spaces, thanks to their interaction compliance and distal dexterity. However, their inherent low stiffness causes a decline in the location accuracy of the robot and could even lead to manipulation failure. To address this challenge, this paper proposes a novel type of rigid-flexible coupling robot, which increases the stiffness of the robot while ensuring the reachability within a narrow space. To achieve high-accuracy location in a narrow space, kinematic and control methods are proposed. Specifically,the robot forward kinematics are uniformly represented, and the closed-form inverse kinematics solution is derived. Furthermore, in cases where the robot?s structure fails to align with Pieper?s solution, a two-stage search strategy is utilized to solve the inverse kinematics, resulting in a high success rate of 99.1%. Based on the proposed kinematics, a rigid-dominated control method is then proposed to facilitate localization and pose alignment of target objects in narrow spaces. The practical comparative experiments show that the proposed robot has the capability of high accuracy control in narrow spaces.

“同时代人”是一个超越年龄、时空的广义内涵的存在,它打破了生理年龄和朝代更迭,以代际划分的“同时代人”的陈见,用一种具有深刻和前瞻意义的理念,聚合成一种具有“当代性”的切分方法,以跨越代际的共同价值观来重塑“同时代人”群体,以此作为解决创作困囿和批评迷惘的突破口。“我们可以使自己成为这些文本的同时代人”的命题,才是需要正视的最本质的问题所在。当下的“同时代人”,既要以史为鉴,从历史的“同时代人”的思想宝库中,汲取属于我们这个时代的相对统一价值观,同时还要引领更多能够聚合在同一价值观下的“同时代人”,发出对整个世界的批判性哲学诘问,这也是改“未完成的现代性”为“当代性”关键词的理由,希冀由此而触及对当代文学治史观念的一种新观念和新方法,在“同时代人”旗帜下,建构起一种基本的人文价值观和学术守则。

基于电晕放电与流体动力学原理,使用COMSOL软件搭建了多物理场耦合模型,对二维线板式电除尘模型进行数值模拟,探究电极电压、颗粒粒径、入口风速、间距对电除尘性能的影响。研究结果表明:提高电极电压增大了电势梯度变化值,提高了除尘效率;粒径增大,颗粒受到的电场力明显提高,除尘效率增大;较低的入口风速有助于颗粒的捕集;极板、极线间距的增大会降低除尘效率。基于本实验模型,在电压为45 kV、粒径为2.5?m、风速为1.0 m/s、板间距为250 mm的工况下,电除尘具有较高的颗粒捕集效率。通过研究各参数对电除尘性能的影响趋势,可为电除尘器满足超低排放改造要求提供合理化建议。

A lightweight road-assistant detection algorithm， EBD-YOLO， based on YOLOv5s is proposed to address the problems of high model complexity， computation cost， and difficulty in deployment on resource-limited embedded terminals in existing assisted driving detection algorithms. First， lightweight Transformer model EfficientViT was used as the backbone feature extraction network of YOLOv5s model to reduce network parameters and calculation costs. Secondly， a Focal-GIoU Loss function is proposed for bounding box regression to accelerate model convergence and reduce loss. Thirdly， the feature pyramid structure is improved to a weighted bi-directional feature pyramid network (BiFPN) to enhance localization and semantic features. Then， a dynamic head framework is added to unify the attention mechanism with the object detection head to improve its performance. Finally， a Soft-CIoU＿NMS algorithm is proposed in the post-processing stage to enhance occluded targets' localization and detection ability and reduce the missed detection rate. We conducted experiments on the KITTI and BDD100K datasets for autonomous driving， and the results showed that the EBD-YOLO model reduced in size by 38.4% and 37.2%， respectively. In comparison， the computational cost was reduced by 48.1%. As measured by mAP@0.5， the detection accuracy improved by 0.5% and 5.8%， respectively， and mAP@0.5:0.95 improved by 2.8% and 7%， respectively. These improvements satisfied the requirements for deployment on embedded terminals in cars.

Random integration of massive distributed photovoltaic (PV) generation poses serious challenges to distribution networks. Voltage violations, line overloads, increased peak–valley differences, and power-flow reversals can occur at different locations, times, and severities. Traditional planning methods such as energy storage (ES) allocation and upgrading of lines may result in poor economics and low equipment utilization. This study proposes a distribution-network planning strategy that coordinates three planning mechanisms:ES allocation to substations and to feeders, and line upgrading. The proposed strategy achieved the lowest annual cost, considering the distribution network problems at different locations, times, and severities. A net load curve description method was first proposed considering economic planning and the uncertain distribution of loads and PVs. Second, a multistage optimization model for ES allocation and line upgrading was established based on the net load curves. Finally, an improved IEEE33 node system was used in the case study. The planning results show that the proposed coordinated planning strategy can address the problems caused by the random integration of massive distributed PVs, improve equipment utilization, and obtain the lowest total annual planning cost.
