He Liu

《工程管理前沿（英文）》 2015年第2卷第4期页码 339-343 doi: 10.15302/J-FEM-2015055

摘要： This paper proposes a new management mode named the persistent integration and innovation management mode to satisfy the requirements by the fast development at oilfields. Taking engineering philosophy as the guidance and technical innovations in petroleum production engineering as the breaking point, the management mode combines long term production practice at oilfields with modern management methods. The management mode integrates intellectuals, techniques, capital, and information and so on to accomplish global optimization of resource configuration. Sets of new techniques, new methods, new technologies and new equipment in petroleum production engineering have been proposed under the guidance of the management mode, achieving great social and economic benefits.

Zhongjun HOU, Renfang WANG, Keyong WANG, Weiyu SHI, Danming XING, Hongchun JIANG

《能源前沿（英文）》 2017年第11卷第3期页码 318-325 doi: 10.1007/s11708-017-0488-0

摘要： The durability of proton exchange membrane fuel cells (PEMFCs) has been posing a key technical challenge to commercial spread of fuel cell vehicles (FCVs). To improve the durability, it is necessary to optimize the fuel cell system (FCS) design against failure modes. The fuel cell durability research method at FCS scale was exhibited, and the failure modes of fuel cell were experimentally investigated in this paper. It is found that the fuel cell dry operation, start/stop cycle and gas diffusion layer (GDL) flooding are typical failure modes of fuel cells. After the modifications against the failure modes, the durability of FCSs is improved to over 3000 h step by step.

Integrated Optimization and Management of Mining Engineering—Coordinative Operation and Optimal Management

An-lin Shao,Rui-yu Yin

《工程管理前沿（英文）》 2014年第1卷第2期页码 153-159 doi: 10.15302/J-FEM-2014023

摘要： In the view of engineering philosophy, the mining engineering is a dynamic operating process of ferrous material flow, in which the ferrous material flow is processed orderly through a series of continual coordinated procedures. It is also a process of discarding the dross, selecting the essential, and extracting the original metal. The object of management is to fulfill the multi-objective optimization. The proportion of lean ores in iron ore resources is 82% in the world and even 97% in China but their utilization is very low. Aiming at the bottleneck and weakness of China’s resource development, this paper analyzes and plans the mining engineering system as a whole based on the ideas and methods of system theory and engineering philosophical thinking. And the paper proposes the “grade decision-based multi-system integration” engineering management mode, which considers the relationship between engineering and environment and complies with the natural law. In the mode, the mining engineering, including geologic mining, ore blending, concentration and pelleting, can be viewed as a whole and the geological grade, mined ore grade, feed grade, concentrate grade and feed grade of blast furnace can be considered comprehensively. The mode reflected the overall structural optimization idea, realized the analysis, coordination and optimization among the multiple functions and processes, and thus drove the overall efficient and profit optimization throughout the processing flow. The establishment and the application of the “grade decision-based multi-system integration” mode have solved the lean iron ores exploitation problem and supported the “self-sufficiency” resource strategy.

《工程管理前沿（英文）》 2015年第2卷第4期页码 351-358 doi: 10.15302/J-FEM-2015060

摘要： Engineering project management is the whole process of project construction management activities up to the point of achieving the goals of engineering construction, which adopts the means of planning, organizing, leading, and controlling. In addition, engineering project management modes are the works of project management and the technical guarantee of project success. For the quality and efficient transformation demands of the Chinese construction industry in the process of marketization, internationalization and informatization, based on the connotation and development path of engineering project management modes, the 16 main and new kinds of project management modes both domestically and abroad are divided into trading mode, financing mode and management mode. These have led to comparative analysis and brief commentary. Finally, it will be pointed out that the engineering project management modes move throughout the whole management process, the combined model and the expansion development of financing model. This work will provide reference for project participants to choose the appropriate project management modes and better understand building company transformation.

Robust SVM-direct torque control of induction motor based on sliding mode controller and sliding mode

Abdelkarim AMMAR,Amor BOUREK,Abdelhamid BENAKCHA

《能源前沿（英文）》 2020年第14卷第4期页码 836-849 doi: 10.1007/s11708-017-0444-z

摘要： This paper proposes a design of control and estimation strategy for induction motor based on the variable structure approach. It describes a coupling of sliding mode direct torque control (DTC) with sliding mode flux and speed observer. This algorithm uses direct torque control basics and the sliding mode approach. A robust electromagnetic torque and flux controllers are designed to overcome the conventional SVM-DTC drawbacks and to ensure fast response and full reference tracking with desired dynamic behavior and low ripple level. The sliding mode controller is used to generate reference voltages in stationary frame and give them to the controlled motor after modulation by a space vector modulation (SVM) inverter. The second aim of this paper is to design a sliding mode speed/flux observer which can improve the control performances by using a sensorless algorithm to get an accurate estimation, and consequently, increase the reliability of the system and decrease the cost of using sensors. The effectiveness of the whole composed control algorithm is investigated in different robustness tests with simulation using Matlab/Simulink and verified by real time experimental implementation based on dS pace 1104 board.

《中国工程科学》 2004年第6卷第7期页码 70-74

摘要：

由于CBC－MAC模式不可并行处理，提出了一种基于双重分组的并行认证模式(PKCB)。PKCB模式同并行认证模式PMAC相比，安全性和速率都有显著提高，PKCB认证模式与CTR（计数器）加密模式结合可构成分组密码算法的一种全工作模式。在此基础上提出了一种基于密钥计数的并行认证模式（KCTR－MAC）。KCTR－MAC模式安全性比PMAC模式高得多，而速率未降低，KCTR－MAC认证模式和CTR加密模式结合也可构成分组密码算法的一种全工作模式（2CTR），2CTR模式的综合性能不亚于标准模式CCM（CTR with CBC－MAC），是一种安全快速的实用模式。

Probabilistic stability of uncertain composite plates and stochastic irregularity in their buckling mode

《结构与土木工程前沿（英文）》页码 179-190 doi: 10.1007/s11709-022-0888-z

摘要： In this study, the mechanical properties of the composite plate were considered Gaussian random fields and their effects on the buckling load and corresponding mode shapes were studied by developing a semi-analytical non-intrusive approach. The random fields were decomposed by the Karhunen−Loève method. The strains were defined based on the assumptions of the first-order and higher-order shear-deformation theories. Stochastic equations of motion were extracted using Euler–Lagrange equations. The probabilistic response space was obtained by employing the non-intrusive polynomial chaos method. Finally, the effect of spatially varying stochastic properties on the critical load of the plate and the irregularity of buckling mode shapes and their sequences were studied for the first time. Our findings showed that different shear deformation plate theories could significantly influence the reliability of thicker plates under compressive loading. It is suggested that a linear relationship exists between the mechanical properties’ variation coefficient and critical loads’ variation coefficient. Also, in modeling the plate properties as random fields, a significant stochastic irregularity is obtained in buckling mode shapes, which is crucial in practical applications.
