A new lanthanide formate oxalate framework [Eu（C2O4）（HCOO）]n （1） has been synthesized via hydrothermal method and characterized by single-crystal X-ray diffraction （SC-XRd）. The framework crystallizes in the orthorhombic Pnma space group, with a = 7.0984（4）, b = 6.6442（3）, c = 10.6793（6）？, V = 503.68（4）？3, Z = 3, C3HO6Eu, Mr = 285.00 g/mol, dc = 3.7581 g/cm3, F（000） = 520.3796, μ = 12.413 mm-1, the final R = 0.0264 and wR = 0.0628 for 797 observed reflections with I 〉 2σ（I）. The photoluminescence （PL） measurements reveal the significant red emission of the framework is dominated by the （5d0 → 7F2） electronic transition at 614 nm. Further variable-temperature powder X-ray diffraction （VT-PXRd） indicates that framework 1 shows slight negative thermal expansion （NTE） along the a-axis, and positive thermal expansion （PTE） along the b and c axes.

Advances in photogrammetry have eased the acquisition of high-resolution digital information from outcrops, enabling faster, non-destructive data capturing and improved reservoir modeling. Geocellular models for flow dynamics with in the virtual outcrop in siliciclastic deposits at different sets of sandstone facies architecture remain, however, a challenge. digital maps of bedding, lithological contrast, spatial-temporal variations of bedding and permeability characteristics make it more easy to understand flow tortuosity in a particular architecture. An ability to precisely model these properties can improve reservoir characterization and flow modeling at different scales. Here we demonstrate the construction of realistic 2 d sandstone facies based models for a pragmatic simulation of flow dynamics using a combination of digital point clouds dataset acquired from LidAR and field investigation of the Sandakan Formation, Sabah, ***, we present methods for enhancing the accuracy of outcrop digital datasets for producing high resolution flow simulation. A well-exposed outcrop from the Sandakan Formation, Sabah, northwest Borneo having a lateral extent of 750 m was chosen in order to implement our research approach. Sandstone facies and its connectivity are well constrained by outcrop observations, data from air-permeability measurements, bilinear interpolation of permeability, grid construction and water vector analysis for flow *** proportions were then enumerated in terms of static digital outcrop model(dOM) and facies model based on sandstone facies bedding characteristics. Flow simulation of water vector analysis through each of the four sandstone facies types show persistent spatial correlation of permeability that align with either cross-bedded orientation or straight with more dispersion high quality sandstone(porosity 21.25%-41.2%and permeability 1265.20-5986.25 md) and moderate quality sandstone(porosity 10.44%-28.75% and permeabili

随着航空界向下一代航空运输系统 (Next-Gen) 迈进，当前的交通警报和防撞系统(TCAS II)可能无法完全保障航空安全，因此如何防止空中碰撞是下一代交通系统的一个重要问题。为解决此问题，本文介绍了一种新技术，用于检测和解决三维(3-d)空域中两架飞机之间的空中交通冲突。首先，该算法计算一组六个决议咨询 (RA) 并结合决断警报时间，以确保不侵犯保护区。该算法提出了三种技术上称为安全规则的解决方案，用于提高飞机面对面、飞机交叉道和飞机超车这三种场景下的安全性。本文将2002年7月1日晚上发生的 überlingen 空中碰撞作为最大的悲剧之一进行了分析，该悲剧导致林肯实验室的研究人员创建了先进的解析算法技术，以应对防撞系统的重大挑战。本文在提出的三个安全规则基础上进行仿真，以验证所提出算法的有效性，仿真结果表明，本文提出的方法相较于传统方法具备一定的优越性。
