资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite location aware information is an emerging area that focuses on automating delivery of spatial information pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive knowledge about construction project status. A two-step algorithm is presented to automate the process of location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite. Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined zone. Reference tags of known locations are used to d

计算mie散射中的散射系数，an，bn，cn，dn 在研究粒子散射问题时很关键-Mie scattering in calculating the scattering coefficient, an, bn, cn, dn in the study of particle scattering problem is critical

这是最小二乘法多项式拟合的算法 很有参考价值的程序,-This is the least squares polynomial fitting algorithm is very useful procedure,

你好，在这里我解释多边形裁剪的算法。时要求切断任何多边形，一般使用剪辑。Cliping上图中所示，通过选择原始的 image(Polygon)，我们就可以减少多边形以平面凸点。从任何角度切割下来的 3D 几何的此应用程序已使用它是砍掉多边形各边的迭代过程。完成此过程之后，你会发现最后多边形裁剪的顶点。在这里我们也找到线段与多边形的脸的交点。
