This paper presents the ARCAD simulator for the rapid development of Unmanned Aerial Systems (UAS), including underactuated and fully-actuated multirotors, fixed-wing aircraft, and Vertical Take-Off and Landing (VTOL) hybrid vehicles. The simulator is designed to accelerate these aircraft's modeling and control design. It provides various analyses of the design and operation, such as wrench-set computation, controller response, and flight optimization. In addition to simulating free flight, it can simulate the physical interaction of the aircraft with its environment. The simulator is written in MATLAB to allow rapid prototyping and is capable of generating graphical visualization of the aircraft and the environment in addition to generating the desired plots. It has been used to develop several real-world multirotor and VTOL applications. The source code is available at https://github.com/keipour/aircraft-simulator-matlab.

随着基于粉末的添加剂制造的快速开发，DepeDdering是去除覆盖3D打印零件的未使用粉末的过程，已成为进一步提高其生产力的主要瓶颈。传统的手动缩减非常耗时且昂贵，并且一些先前的自动化系统要么需要预处理或缺乏对不同3D打印零件的适应性。为了解决这些问题，我们引入了一个机器人系统，该机器人系统会自动从3D打印零件的表面上去除未加入的粉末。关键组件是一个视觉感知系统，该系统由一个姿势跟踪模块组成，该模块可实时跟踪6D姿势的粉末封闭零件，以及一个估计缩减完成百分比的进度估计模块。跟踪模块可以在高达60 fps的笔记本电脑CPU上有效运行。实验表明，我们的退化系统可以从各种3D打印零件的表面上除去未持续的粉末，而不会造成任何损坏。据我们所知，这是第一个基于视觉的机器人脱皮系统之一，可适应各种形状的部分而无需预多供款。

机器人需要多种互动模式来与人类在复杂的工业任务中进行稳健合作。我们开发了共存和共存（可可）人类机器人协作系统。共存模式使机器人能够在共享空间中独立地与人类在不同子任务上合作。合作模式使机器人能够遵循人类的指导并恢复失败。人类意图跟踪算法将人类和机器人运动测量作为输入，并提供了交互模式的开关。我们证明了可可系统在用例中类似于现实世界多步组件任务的有效性。

Enabling vertical take-off and landing while providing the ability to fly long ranges opens the door to a wide range of new real-world aircraft applications while improving many existing tasks. Tiltrotor vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs) are a better choice than fixed-wing and multirotor aircraft for such applications. Prior works on these aircraft have addressed aerodynamic performance, design, modeling, and control. However, a less explored area is the study of their potential fault tolerance due to their inherent redundancy, which allows them to tolerate some degree of actuation failure. This paper introduces tolerance to several types of actuator failures in a tiltrotor VTOL aircraft. We discuss the design and modeling of a custom tiltrotor VTOL UAV, which is a combination of a fixed-wing aircraft and a quadrotor with tilting rotors, where the four propellers can be rotated individually. Then, we analyze the feasible wrench space the vehicle can generate and design the dynamic control allocation so that the system can adapt to actuator failures, benefiting from the configuration redundancy. The proposed approach is lightweight and is implemented as an extension to an already-existing flight control stack. Extensive experiments validate that the system can maintain the controlled flight under different actuator failures. To the best of our knowledge, this work is the first study of the tiltrotor VTOL's fault-tolerance that exploits the configuration redundancy.

协作机器人需要有效的人类意图估算，以便在诸如人类意图不断变化的工业集会等结构化任务中安全，平稳地与人类合作。我们提出了意图跟踪的概念，并引入了一个协作机器人系统，该系统同时跟踪层次级别的意图。跟踪高级意图以估计人类的相互作用模式，并使机器人能够（1）避免与人碰撞以最大程度地减少中断或（2）帮助人类纠正失败。低级意图估算为机器人提供了特定任务的信息，以进行并发执行。我们在UR5E机器人上实现了该系统，并通过消融试验性研究在组装用例中展示了强大的，无缝和人体工程学的人类机器人协作。

我们研究了密集和互动人群中安全和意图意识到的机器人导航的问题。大多数以前的强化学习（RL）方法无法考虑所有代理之间的不同类型的相互作用或忽略人的意图，从而导致绩效降级。在本文中，我们提出了一个新型的复发图神经网络，具有注意机制，以通过空间和时间捕获代理之间的异质相互作用。为了鼓励长远的机器人行为，我们通过预测其未来的轨迹在几个时间段中来推断动态代理的意图。预测被纳入无模型的RL框架中，以防止机器人侵入其他试剂的预期路径。我们证明我们的方法使机器人能够在挑战人群导航方案中实现良好的导航性能和无侵入性。我们成功地将模拟中学到的政策转移到了现实世界中的Turtlebot 2i。

本文提出了一种类别级别的6D对象姿势和形状估计方法IDAPS，其允许在类别中跟踪6D姿势并估计其3D形状。我们使用深度图像作为输入开发类别级别自动编码器网络，其中来自自动编码器编码的特征嵌入在类别中对象的姿势。自动编码器可用于粒子过滤器框架，以估计和跟踪类别中的对象的姿势。通过利用基于符号距离函数的隐式形状表示，我们构建延迟网络以估计给定对象的估计姿势的3D形状的潜在表示。然后，估计的姿势和形状可用于以迭代方式互相更新。我们的类别级别6D对象姿势和形状估计流水线仅需要2D检测和分段进行初始化。我们在公开的数据集中评估我们的方法，并展示其有效性。特别是，我们的方法在形状估计上实现了相对高的准确性。

As natural language processing (NLP) for gender bias becomes a significant interdisciplinary topic, the prevalent data-driven techniques such as large-scale language models suffer from data inadequacy and biased corpus, especially for languages with insufficient resources such as Chinese. To this end, we propose a Chinese cOrpus foR Gender bIas Probing and Mitigation CORGI-PM, which contains 32.9k sentences with high-quality labels derived by following an annotation scheme specifically developed for gender bias in the Chinese context. Moreover, we address three challenges for automatic textual gender bias mitigation, which requires the models to detect, classify, and mitigate textual gender bias. We also conduct experiments with state-of-the-art language models to provide baselines. To our best knowledge, CORGI-PM is the first sentence-level Chinese corpus for gender bias probing and mitigation.

Advances in computer vision and machine learning techniques have led to significant development in 2D and 3D human pose estimation from RGB cameras, LiDAR, and radars. However, human pose estimation from images is adversely affected by occlusion and lighting, which are common in many scenarios of interest. Radar and LiDAR technologies, on the other hand, need specialized hardware that is expensive and power-intensive. Furthermore, placing these sensors in non-public areas raises significant privacy concerns. To address these limitations, recent research has explored the use of WiFi antennas (1D sensors) for body segmentation and key-point body detection. This paper further expands on the use of the WiFi signal in combination with deep learning architectures, commonly used in computer vision, to estimate dense human pose correspondence. We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input. This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing.

As an important variant of entity alignment (EA), multi-modal entity alignment (MMEA) aims to discover identical entities across different knowledge graphs (KGs) with multiple modalities like images. However, current MMEA algorithms all adopt KG-level modality fusion strategies but ignore modality differences among individual entities, hurting the robustness to potential noise involved in modalities (e.g., unidentifiable images and relations). In this paper we present MEAformer, a multi-modal entity alignment transformer approach for meta modality hybrid, to dynamically predict the mutual correlation coefficients among modalities for instance-level feature fusion. A modal-aware hard entity replay strategy is also proposed for addressing vague entity details. Extensive experimental results show that our model not only achieves SOTA performance on multiple training scenarios including supervised, unsupervised, iterative, and low resource, but also has limited parameters, optimistic speed, and good interpretability. Our code will be available soon.
