Federated Foundation Models (FedFMs) represent a distributed learning paradigm that fuses general competences of foundation models as well privacy-preserving capabilities federated learning. This combination allows the large and small local domain at remote clients to learn from each other in teacher-student setting. paper provides comprehensive summary ten challenging problems inherent FedFMs, encompassing foundational theory, utilization private data, continual learning, unlearning,...
This paper proposes a new approach to design pinion machine tool-settings for spiral bevel gears by controlling contact path and transmission errors. It is based on the satisfaction of condition three given control points tooth surface. The meshing are controlled be predesigned straight that meets pre-designed parabolic function Designed separately, magnitude errors orientation subjected precise control.

A method is proposed to manufacture spiral bevel gear by duplex spread blade based on 4-axis CNC milling machine. Firstly, the geometry parameters and machine-tool settings are comprehensively considered. To meet with tooth taper, a new way raised select reference point. Then calculated that only first-order mesh performance guaranteed in Therefore conjugate surface modified represented as second-order polynomial optimize performance, result target established, according sensitivity matrix...
Summary This paper investigates an observer‐based adaptive robust fuzzy formation tracking control method for nonlinear multi‐agent systems (MAS) with input delay. The considered MAS contains the unknown functions, that is, unmeasured states. logic (FLS) are used to approximate and then a state observer is designed estimate Pade approximation approach introduced solve delay issue. By combining command filtering backstepping recursive techniques, prescribed performance output feedback...
摘要： 为了得到准确的螺旋锥齿轮数字孪生体模态参数，通过螺旋锥齿轮的模态试验，得到了自由模态的模态频率、模态振型、频响函数；计算了自模态置信准则度矩阵(Auto MAC)，各阶模态相关性很低，表明模态试验提取的模态振型具有较好的准确性。以各阶试验模态频率为目标，修正螺旋锥齿轮的物理属性并进行模态仿真，得到自由模态的模态频率、模态振型、频响函数。与模态试验结果对比，最大模态频率偏差为1.235%；计算了试验与数字孪生体模态振型的互模态置信准则度矩阵(Cross MAC)，表明数字孪生体模态振型与试验模态振型具有较好的一致性；试验和仿真频响函数对比进一步验证了数字孪生体模态分析的准确性。对数字孪生体的模态仿真不仅可以辨识出由于试验条件限制无法测试出的模态参数；通过试验与仿真模态振型Cross MAC与试验模态振型的Auto MAC对比，还可以识别出试验误差较大的模态参数。试验和仿真对比分析表明本文方法构造的螺旋锥齿轮数字孪生体模型是准确的，可以解决由于试验条件限制测不全和测不准的问题。
