对钻井海外项目党建工作的调研与思考

钻井海外项目党组织不断创新工作思路,大力强化员工教育,积极扩大典型效应,有力地发挥了党组织拓展海外市场的积极保障作用,但由于点多、面广、线长,人员具有流动性、分散性,地域具有艰苦性、危险性等特点给党建工作带来了很大的难度。要不断完善改进海外项目党建工作,就必须要加强海外政工干部培训和党员教育管理,把握海外党建工作的标准和尺度,以党性实践活动为载体,打造强有力的战斗堡垒。     

浅谈在油田搬迁单位人文关怀的实施

中国石化江汉油田分公司采油工艺研究院在搬迁到了武汉后,部分职工出现了缺乏危机意识、心理焦虑等问题。而人文关怀是维护队伍稳定的基础、调解职工心理的手段、企业顺利发展的保证。企业实施人文关怀,就必须加强心理健康教育、构建和谐人际关系、做好细致心理疏导、解决职工实际问题、关注员工价值取向。     

不良行为在团队网络中传播的动力学仿真及实例分析

针对不良行为传播过程难以分析的问题,提出一种基于复杂网络理论和系统动力学的模拟演化方法.该方法将团队映射为复杂网络,建立具有易染态、不良态、改良态、移除态、离职态的SBIRD模型,并结合权值度和簇系数对模型中的传播率、消除率、改良率等参数以及系统初始值加以实例分析.实例仿真表明:该方法能够有效地对不良行为传播过程进行分析,并辅助企业对团队中不良行为实施管理与控制.     

瑞利信道下线性分组码的分集增益研究

比较AWGN信道与瑞利信道的误码性能,研究瑞利信道下分集支数与信息传输可靠性之间的关系。推导线性分组码在瑞利信道下误码率上界的理论表达式,得到分集增益与其最小汉明距离的关系。基于蒙特卡洛法对误码性能进行仿真,并与理论误码率上界进行比较,结果表明线性分组码在瑞利信道下获得的分集增益等于其最小码距。     

In-plane directional mechanical properties of carbon fabric skins in sandwich structures after thermoforming

In this paper, a representative unit volume finite element (RUV FE) model was employed to simulate thermoforming process of carbon fabric-polymeric foam sandwich structures. Thermoforming simulations, which capture crimp angles and amplitude changes of carbon fabric with respect to different operational pressure, were conducted with the help of RUV FE model. Micro-deformation of tow structures after thermoforming was rigorously reflected in the second stage FE model to determine the in-plane directional stiffness of skin parts. Tensile tests were carried out to investigate mechanical properties of skin parts in sandwich structures for the potential usage of automotives, electronic housings or the satellite structure design.     

White organic light-emitting diodes from three emitter layers

Three-wavelength white organic light-emitting diodes (WOLEDs) were fabricated using two doped layers, which were obtained by separating the recombination zones into three emitter layers. A sky blue emission originated from the 4,4′-bis(2,2′-diphenylethen-1-yl)biphenyl (DPVBi) layer. A green emission originated from a tris(8-quinolinolato)aluminum (III) (Alq₃) host doped with a green fluorescent 10-(2-benzothiazolyl)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H,11H-[1]benzopyrano [6,7,8-ij]-quinolizin-11-one (C545T) dye. An orange emission was obtained from the N,N′-bis(1-naphthyl)-N,N′-diphenyl-1,1′-biphenyl-4,4′-diamine (NPB) host doped with a red fluorescent dye, 4-(dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB). A white light resulted from the partial excitations of these three emitter layers by controlling the layer thickness and concentration of the fluorescent dyes in each emissive layer simultaneously. The electroluminescent spectrum of the device was not sensitive to the driving voltage of the device. The white light device showed a maximum luminance of approximately 53,000 cd/m². The external quantum and power efficiency at a luminance of approximately 100 cd/m² were 2.62% and 3.04 lm/W, respectively.

Symmetry and symmetry-breaking in multiagent behavior

This paper presents some results about properties of the spatial behavior of systems consisting of many artificial agents (robots). The general goal is to understand how the complexity of group behavior is related to individual behavior, and how differences arise and can be grounded. We argue that symmetry and symmetry-breaking are essential factors for the organization of spatial group behavior. They can serve as guiding principles for the construction of agents for real-world environments. This work was presented, in part, at the Second International Symposium on Artifical Life and Robotics, Oita, Japan, February 18–20, 1997
