A common characteristic in integer linear programs (ILPs) is symmetry, allowing variables to be permuted without altering the underlying problem structure. Recently, GNNs have emerged as a promising approach for solving ILPs. However, significant challenge arises when applying ILPs with symmetry: classic GNN architectures struggle differentiate between symmetric variables, which limits their predictive accuracy. In this work, we investigate properties of permutation equivariance and...
The Chang’e project has completed a sampling mission of the shallow lunar soil layer; however, exploration deep rock layer remains unaddressed. To further investigate feasibility drilling and identify factors affecting rate penetration (ROP) power in low-temperature, H2O less environment, model was developed. This study utilized Box–Behnken method to design response surface experiment, where number polycrystalline diamond compact (PDC) cutters, backward inclination angle, chip removal...
AlGaN-based deep ultraviolet (DUV) light emitting diodes (LEDs) are irradiated by fast neutrons, with optical and electrical properties analyzed in detail. Significant enhancement of output power is observed under neutron irradiation fluences 6.0 × 1012 1.5 1013 cm−2. However, the device exhibits performance degradation as fluence increases to 1.0 1014 As previous observations limited degradation. Further analysis reveals that there exist two different competitive mechanisms radiation effect...
A systematic and comprehensive study on the design, construction testing of large scale Ⅲ～Ⅳ grade wet-collapsible loess foundation treatment by 8000 kN•m high energy dynamic compaction is done in this paper. Effect for collapsible analyzed through Rayleigh wave velocity test, standard penetration lab soil test static cone test. By comparison with physical mechanical properties index without treatment, effective reinforcement depth, elimination collapsibility bearing capacity are found to...
Air traffic scenario evaluation can support the optimisation of flow and airspace configuration to improve safety air control.

摘要: 为了解采样机具与模拟月壤间的相互作用,同时验证月壤采样机具模块化建模的可行性.基于中国地质大学(武汉)研制的CUG-1A型模拟月壤,开展不同条件下机具贯入力载的试验研究,并依据试验结果建立理论模型进行验证.各机具在浅层模拟月壤贯入阻力平均增长率为19.9%,次浅层提升至38.18%,深层出现陡增达到63.43%;贯入速度对贯入阻力的平均误差为2.5%;不同入土角度下贯入阻力的平均增长率为62.85%;不同截面机具贯入阻力随截面面积增长而增长,值近似为1∶2∶3∶4.同时进行了机具结构模块化验证,理论模型与试验结果吻合度在85%以上.采样机具所受贯入阻力与贯入深度、方式和机具结构明显相关,可建立模块化理论模型准确预估不同条件机具的贯入阻力. 关键词: 表层贯入 / 模块化 贯入阻力 机土作用 模拟月壤 土力学 工程地质
The cold forging process of large module spur gear with four modules and 59mm breadth is performed by means numerical simulation method. Two processes to forming such gears were compared the method, one closed-die performing extrusion in finish-forging, other divided-flow method finish-forging. Especially, analyzed detail. necessary reference basis realize practical precision modulus provided eventually.
Because there are less restrictions in space, a variety of different movement patterns and equipment structures may be used during the process planetary surface sampling. Traditionally, optimal analysis for sampling is focused on specific movements; contrast, new modular motion-structure design model sampling, which more flexible model, discussed this paper. By establishing combining two basic module groups, namely, motion group structure group, can define analyse multiple structures. For...
