《机械工程前沿（英文）》 2010年第5卷第3期页码 316-321 doi: 10.1007/s11465-010-0021-1

摘要： According to the deficiencies of remote calibration mode based on material object reference, a new model of a remote calibration system for frequency based on in-place benchmark is introduced, which is made of a calibration subsystem on the spot and a remote management subsystem. The key technology of some key problems for the remote calibration system is particularly discussed, including the time and frequency benchmark receiving module based on global positioning system (GPS), frequency comparison based on a phase method, frequency division based on dual high-frequency phase locked loop (PLL), and remote calibration based on the web. The results show that the system possesses some characteristics, such as high precision, good versatility, and no limitation of time and place.

Conceptual design and kinematic analysis of a novel parallel robot for high-speed pick-and-place operations

Qizhi MENG, Fugui XIE, Xin-Jun LIU

《机械工程前沿（英文）》 2018年第13卷第2期页码 211-224 doi: 10.1007/s11465-018-0471-4

摘要：

This paper deals with the conceptual design, kinematic analysis and workspace identification of a novel four degrees-of-freedom (DOFs) high-speed spatial parallel robot for pick-and-place operations. The proposed spatial parallel robot consists of a base, four arms and a 1½ mobile platform. The mobile platform is a major innovation that avoids output singularity and offers the advantages of both single and double platforms. To investigate the characteristics of the robot’s DOFs, a line graph method based on Grassmann line geometry is adopted in mobility analysis. In addition, the inverse kinematics is derived, and the constraint conditions to identify the correct solution are also provided. On the basis of the proposed concept, the workspace of the robot is identified using a set of presupposed parameters by taking input and output transmission index as the performance evaluation criteria.

《能源前沿（英文）》 2014年第8卷第3期页码 379-385 doi: 10.1007/s11708-014-0328-4

摘要： This paper discussed a comparative study of several state-of-art methods for determining building energy consumption benchmark. A new approach, which combined the idea of “building benchmark” and “operational benchmark” in its rating system, was proposed. A case study was conducted which applied the proposed approach to benchmarking an existing office building in Tianjin. Besides, the calculation of benchmarks of the reference building model and real building model using the rating method in eQUEST was also considered. Furthermore, the simulation results of the reference building model were taken as the baseline to divide real office buildings into different energy performance grades.

General modeling and optimization technique for real-world earth observation satellite scheduling

《工程管理前沿（英文）》页码 695-709 doi: 10.1007/s42524-023-0263-3

摘要： Over the last two decades, many modeling and optimization techniques have been developed for earth observation satellite (EOS) scheduling problems, but few of them show good generality to be engineered in real-world applications. This study proposes a general modeling and optimization technique for common and real-world EOS scheduling cases; it includes a decoupled framework, a general modeling method, and an easy-to-use algorithm library. In this technique, a framework that decouples the modeling, constraints, and optimization of EOS scheduling problems is built. With this framework, the EOS scheduling problems are appropriately modeled in a general manner, where the executable opportunity, another format of the well-known visible time window per EOS operation, is viewed as a selectable resource to be optimized. On this basis, 10 types of optimization algorithms, such as Tabu search and genetic algorithm, and a parallel competitive memetic algorithm, are developed. For simplified EOS scheduling problems, the proposed technique shows better performance in applicability and effectiveness than the state-of-the-art algorithms. In addition, a complicatedly constrained real-world benchmark exampled by a four-EOS Chinese commercial constellation is provided, and the technique is qualified and outperforms the in-use scheduling system by more than 50%.

《中国工程科学》 2012年第14卷第1期页码 26-30

摘要：

通过数值模拟计算，对DX单桩的沉降和承载力特性进行了研究，分析了在相同的桩长、桩径等条件下直孔桩、两个承力盘DX桩和三个承力盘DX桩的性能差异。沉降方面，在桩顶荷载增加相同的情况下，两个承力盘DX桩对桩顶沉降的控制明显强于普通直孔桩的控制效果，三个承力盘DX桩则进一步优越于两个承力盘DX桩。承载力方面，两个承力盘DX单桩的抗压承载力大约为直孔桩的1.5倍，而三个承力盘DX桩又进一步优越，大约为两个承力盘DX桩的1.2倍。

Modification of the activated sludge model for chemical dosage

《环境科学与工程前沿（英文）》 2015年第9卷第4期页码 694-701 doi: 10.1007/s11783-014-0732-3

摘要： Full-scale experiments have been carried out to adapt the activated sludge model ASM2d to include the influence of metal dosage (Fe and Al ) for phosphorus removal. Phosphorus removal rates, nitrification rates, as well as pH and sludge settling performance, were evaluated as functions of the metal dosages. Furthermore, models relating certain parameters to the dosage of chemicals have been derived. Corresponding parameters in the ASM2d and the secondary settler models, included in the Benchmark Simulation Model No 1 (BSM1), have been modified to take the metal influence into consideration. Based on the effluent limits and penalty policy of China, an equivalent evaluation method was derived for the total cost assessment. A large number of 300-day steady-state and 14-day open-loop dynamic simulations were performed to demonstrate the difference in behavior between the original and the modified BSM1. The results show that 1) both in low and high mole concentrations, Fe addition results in a higher phosphorus removal rate than Al ; 2) the sludge settling velocity will increase due to the metal addition; 3) the respiration rate of the activated sludge is decreased more by the dosage of Al than Fe ; 4) the inhibition of Al on the nitrification rate is stronger than that of Fe ; 5) the total operating cost will reach the minimum point for smaller dosages of Fe , but always increase with Al addition.

摘要：

通过数值计算软件FLAC3D对DX旋挖挤扩灌注桩（简称DX桩）群桩的承载性状和桩周土体的沉降规律进行了研究。分析了桩间距、承力盘布置对群桩极限承载力和沉降控制能力的影响，并比较了6根基桩的DX群桩和8根基桩的直桩群桩的极限承载力。研究结果表明：DX群桩的基桩具有DX单桩的受力性状。承力盘下方土体位移大于承力盘上方土体位移，盘腔上部出现临空面。3D(D为盘径)桩间距的承载力和沉降控制能力最佳。同一地层内，承力盘布置方式（平行、错开布置）对DX群桩的承载力影响甚微。6根基桩的DX群桩的极限承载力是8根基桩的直

基于定量属性的单目标视觉跟踪算法评价体系研究 Article

Wen-jing KANG, Chang LIU, Gong-liang LIU

《信息与电子工程前沿（英文）》 2020年第21卷第3期页码 405-421 doi: 10.1631/FITEE.1900245

摘要：视觉跟踪是计算机视觉领域热门研究课题之一。近年来，很多先进跟踪算法和性能评价基准相继发布，并取得巨大成功。现有评价体系大多定位于衡量整体性能，无法通过针对性的详细论证评估跟踪器的优势和缺点，且很多常用评测指标缺乏令人信服的含义解释。本文从测试数据、测试方法、测试指标3方面深入分析跟踪评价体系的细节。首先，归纳整理了12个反映图像序列不同特性的帧间视觉属性，并首次定量给出其归一化公式。基于这些属性定义，提出两种新的测试方法，即基于相关性的测试和基于权重的测试，使评价体系能更直观、更清晰地评定跟踪器各方面性能。然后，将所提测试方法应用于著名的跟踪挑战赛，即Video Object Tracking (VOT) Challenge 2017。测试结果表明，在目标尺寸快速或剧烈变化时，跟踪器大多表现不佳，即使基于深度学习的先进跟踪器也未能很好解决这一问题。此外发现，中心位置差错（center location error，CLE）性能指标虽未考虑到目标尺度，在实际测试中仍对目标尺寸变化很敏感。

TextGen：用于新型存储系统基准测试的真实文本数据集生成方法 Article

Long-xiang WANG,Xiao-she DONG,Xing-jun ZHANG,Yin-feng WANG,Tao JU,Guo-fu FENG

《信息与电子工程前沿（英文）》 2016年第17卷第10期页码 982-993 doi: 10.1631/FITEE.1500332

摘要：概要：新型存储系统通过内置数据压缩功能提高性能，并节省存储空间。因此，数据内容会显著影响存储系统基准测试结果。由于真实数据集规模庞大，难以复制到目标测试系统，并且大多数数据集由于隐私性无法进行共享。因此，基准测试程序需要人工生成测试数据集。为了保证测试结果的准确性，需要根据影响存储系统性能的真实数据集特征信息生成数据。现有方法SDGen在字节级别上分析真实数据集内容分布特征，并以此生成数据集，因此能够保证内置字节级压缩算法的存储系统测试结果准确。但是SDGen并未分析真实数据集的词级别内容分布特征，因此不能保证内置词级别压缩算法的存储系统测试结果准确，本文提出了一种基于Lognormal概率分布模型的文本数据集生成方法TextGen。该方法根据真实数据集的词切分结果建立语料库，分析语料库中词的分布特征，利用最大似然估计得到词分布的Lognormal模型参数，根据模型采用蒙特卡洛方法生成数据内容。该方法生成数据集所消耗的时间只与生成数据集规模相关，具有线性的时间复杂度O(n)。本文收集了四种数据集验证方法有效性，并通过一种典型的词级别压缩算法——ETDC（End-Tagged Dense Code）进行测试。实验结果表明：相比SDGen，TextGen生成文本数据集性能更高，并且，生成数据集用于压缩测试后与真实数据集的压缩速率、压缩率相似程度更高。

《中国工程科学》 2013年第15卷第8期页码 99-103

摘要：

在节段预制拼装桥梁的墩顶节段，常常采用后浇横隔梁的方式来减轻吊装重量。后浇横隔梁在体量上属于大体积混凝土，混凝土水化热问题会引起一些部位拉应力过大，如控制措施不合理，往往会导致预制梁段在施工阶段的开裂。本文结合南京长江第四大桥的引桥工程，基于三维瞬态温度场理论，利用通用有限元程序ANSYS对墩顶梁段现浇块的水化热效应进行了数值仿真，研究箱梁水化热温度场和应力场的分布规律。分析结果表明，水化热引起的箱梁腹板外侧拉应力水平足以导致混凝土开裂，在水化热测试试验中也观测到了箱梁腹板外侧的纵向微裂缝，与分析相符。在研究水化热温度场和应力场分布规律的基础上，进行了控制水化热温度应力的措施研究，在实桥施工中证实是切实有效的。

The Tong Test: Evaluating Artificial General Intelligence Through Dynamic Embodied Physical and Social Interactions

《工程（英文）》 doi: 10.1016/j.eng.2023.07.006

摘要： The release of the generative pre-trained transformer (GPT) series has brought artificial general intelligence (AGI) to the forefront of the artificial intelligence (AI) field once again. However, the questions of how to define and evaluate AGI remain unclear. This perspective article proposes that the evaluation of AGI should be rooted in dynamic embodied physical and social interactions (DEPSI). More specifically, we propose five critical characteristics to be considered as AGI benchmarks and suggest the Tong test as an AGI evaluation system. The Tong test describes a value- and ability-oriented testing system that delineates five levels of AGI milestones through a virtual environment with DEPSI, allowing for infinite task generation. We contrast the Tong test with classical AI testing systems in terms of various aspects and propose a systematic evaluation system to promote standardized, quantitative, and objective benchmarks and evaluation of AGI.
