Abstract Projection-based multimodal 3D semantic segmentation methods suffer from information loss during the point cloud projection process. This issue becomes more prominent for small objects. Moreover, the alignment of sparse target features with the corresponding object features in the camera image during the fusion process is inaccurate, leading to low segmentation accuracy for small objects. Therefore, we propose an attention-based multimodal feature alignment and fusion network module. This module aggregates features in spatial directions and generates attention matrices. Through this transformation, the module could capture remote dependencies of features in one spatial direction. This helps our network precisely locate objects and establish relationships between similar features. It enables the adaptive alignment of sparse target features with the corresponding object features in the camera image, resulting in a better fusion of the two modalities. We validate our method on the nuScenes-lidar seg dataset. Our CAFNet achieves an improvement in segmentation accuracy for small objects with fewer points compared to the baseline network, such as bicycles (6% improvement), pedestrians (2.1% improvement), and traffic cones (0.9% improvement).
基于投影的多模态三维语义分割方法在点云投影过程中存在信息丢失的问题。这个问题对于小对象来说更加突出。此外,在融合过程中,稀疏目标特征与相机图像中相应目标特征的对齐不准确,导致小目标的分割精度较低。因此,我们提出了一个基于注意力的多模态特征对齐与融合网络模块。该模块聚合空间方向上的特征,生成注意力矩阵。通过这种转换,该模块可以在一个空间方向上捕获特征的远程依赖关系。这有助于我们的网络精确定位对象,并在相似特征之间建立关系。它可以使稀疏目标特征与相机图像中相应的目标特征自适应对齐,从而更好地融合两种模态。我们在nuScenes-lidar seg数据集上验证了我们的方法。与基线网络相比,我们的CAFNet在点较少的小物体上实现了分割精度的提高,例如自行车(提高6%),行人(提高2.1%)和交通锥(提高0.9%)。

Abstract Due to the differences in the line resistance of each distributed generation unit, conventional sag control does not allow for precise distribution of power, which also reduces the problem of system reactive power accuracy. To address this problem, this paper analyzes the power equalization and distribution conditions. A method for adaptive adjustment of virtual resistance by system output power feedback is submitted. Reducing the variance among the original line resistances aims to solve the problem of power not being evenly divided and improve the equalization of reactive power. By building a Simulink parallel simulation model of the inverter, it is verified that the power feedback-based fetching and the improved droop control is effective.
摘要由于各分布式发电机组的线路电阻存在差异,常规的暂降控制无法实现功率的精确分配,也降低了系统无功功率精度的问题。针对这一问题,本文分析了电力均衡和分配条件。提出了一种利用系统输出功率反馈自适应调整虚电阻的方法。减小原始线路电阻之间的方差是为了解决功率分配不均匀的问题,提高无功功率的均衡性。通过建立逆变器的Simulink并行仿真模型,验证了基于功率反馈的抓取和改进的下垂控制的有效性。

Abstract Considering the application of biomass energy, the Biomass Integrated Energy System (BIES) was first constructed. An integrated energy system operation optimization model was proposed with the objective functions of minimizing economic costs and maximizing clean energy utilization. Secondly, according to the characteristics of biomass Cogeneration, the scheme of adjusting the ratio of heat and power is proposed. Finally, a simulation analysis was conducted on a certain region in China. The results indicate that utilizing biomass energy in an integrated energy system can greatly reduce operating costs and improve energy utilization efficiency. After the heat-to-power ratio is adjusted, economic costs can be reduced again by 7.66%, and clean energy utilization can be increased by 6.15%.

Abstract This study aims to empirically prove the Torricelli equation formula in the case of leaky reservoirs with the help of video tracker analysis. The method used in this research is quantitative descriptive. The experiment was carried out with a simple tool: a 19-liter gallon of water filled with water and dyed, and then three holes were made vertically with different heights. The gallon is filled with water with a constant water level. Next, take a video of each leaking hole. Video is analyzed with Tracker software. Variables observed were the velocity of water exiting from the leak point ( v ), the time it took for water to gush from the leak point to the bottom ( t ), and the horizontal distance from the leak point position to the bottom ( x ). The results obtained based on video analysis with the tracker are that the farther the distance from the surface of the water to the leak point, the farther the horizontal distance of the resulting jet of water will be. This study concludes that theoretical data and experimental data have significant value, so the video analysis tracker software is feasible to use in dynamic and static fluid learning.
摘要本研究旨在借助视频跟踪器分析,对漏泄油藏情况下的托里拆利方程公式进行实证证明。本研究采用定量描述方法。实验是用一个简单的工具进行的:一加仑19升的水装满水并染色,然后垂直地打三个不同高度的洞。加仑装满了恒定水位的水。接下来,拍下每个渗漏孔的视频。用Tracker软件分析视频。观察到的变量是水从泄漏点流出的速度(v),水从泄漏点喷涌到底部所需的时间(t),以及泄漏点位置到底部的水平距离(x)。基于跟踪器的视频分析结果表明,从水面到泄漏点的距离越远,产生的水射流的水平距离越远。研究结果表明,理论数据和实验数据都具有重要的价值,因此视频分析跟踪软件在动态和静态流体学习中都是可行的。

Abstract The finned tube heat exchanger is the core component of the flue gas waste heat utilization system. In order to optimize and control the heat transfer efficiency of the heat exchanger in real time under smart heating conditions, we use the entransy dissipation thermal resistance as a kernel index to assess its heat exchange performance, and Trnsys simulation software is employed to figure out the influence of heat exchanger operating parameters (flue gas inlet velocity) and fin structure parameters (fin height, fin pitch) on heat exchanger heat transfer characteristics. The results show that in a reasonable range, increasing the flue gas inlet velocity can decrease the irreversible loss of heat transfer, obviously improving the heat transfer effect. The pitch and height of the fin also have a large impact on the performance of heat transfer. To significantly promote the performance of the heat exchanger, it is useful to reduce the pitch of the fin and increase the fin height within a reasonable range.

Abstract Optical communication networks are vital in the digital era, but data transmission becomes weak the longer the distance traveled by light. Erbium-Doped Fiber Amplifier (EDFA) technology is commonly used as an optical amplifier, but it still produces a small gain, Q-factor, and a significant noise figure. This study characterized the Hybrid Optical Amplifier (HOA) combinations that contain EDFA with various doped fibers. The characterization was performed through Optisystem software simulation by observing and analyzing the gain, noise of figure, and Q-factor generated by each doped fiber variant. The results showed that the combination of Ytterbium-doped Fiber produced the most significant gain of 15.83 dB, less noise figure of 5,661 dB, and a relatively high Q-factor of 35,615 at 1,550 nm. It indicates that the HOA combination is suitable and ideal for long-distance transmission in fiber optic communication network applications.

Abstract In the 21 st century, students are required to have skills, one of which is Critical Thinking Skill (CTS) in physics learning. Physics aims to master concepts and principles to solve problems by applying critical thinking skills in physics learning. This study aims to analyze the CTS profile of Senior High School (SHS) in physics learning. This current research is pre-research with 107 of 10 th grade students as participants. This research was conducted in a high school in Indonesia. CTS has four indicators: interpretation, analysis, evaluation, and inference. In this study, the CTS profile of high school students in physics learning is still low. The implications of this study can be used as a bridge as clear evidence that the CTS of SHS students in physics learning is still low and needs to be leveled up.
摘要21世纪的物理学习要求学生具备各种技能,其中之一就是批判性思维能力。物理旨在通过在物理学习中运用批判性思维技能,掌握解决问题的概念和原理。本研究旨在分析高中生物理学习中的CTS特征。本研究为预研究,以107名10年级学生为研究对象。这项研究是在印度尼西亚的一所高中进行的。CTS有四个指标:解释、分析、评价和推断。在本研究中,高中生在物理学习中的CTS特征仍然很低。本研究的启示可以作为一个桥梁,清楚地证明高中学生在物理学习中的CTS仍然很低,需要提高。
