SPHysics is a platform of Smoothed Particle Hydrodynamics (SPH) codes inspired by the formulation of Monaghan (1992) developed jointly by researchers at the Johns Hopkins University (U.S.A.), the University of Vigo (Spain), the University of Manchester (U.K.) and the University of Rome La Sapienza (Italy). Developed over a number of years primarily to study free-surface flow phenomena where Eulerian methods can be difficult to apply, such as waves, impact of dam-breaks on off-shore structures.

TDOA算法是对TOA算法的改进，他不是直接利用信号到达时间，而是用多个基站接收到信号的时间差来确定移动台位置，与TOA算法相比他不需要加入专门的时间戳，定位精度也有所提高。TDOA值的获取一般有2种形式：第1种形式是利用移动台到达2个基站的时间TOA，取其差值来获得，这时仍需要基站时间的严格同步，但是当两基站间移动信道传输特性相似时，可减少由多径效应带来的误差

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
