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

DFPD是Directional Filtering and a posteriori Decision的缩写，计算复杂度低，对高频区域处理效果比某些高复杂度高的算法还要好。

Differential evolution: A simple and efficient heuristic for global optimization over continuous spaces. This code implements a basic multi-objective optimization algorithm based on Diferential Evolution (DE) algorithm. When one objective is optimized, the standard DE runs; if two or more objectives are optimized, the greedy selection step in DE algorithm is performed using a dominance relation.

蒙特卡罗方法又称随机抽样技巧或统计试验方法。半个多世纪以来，由于科学技术的发展和电子计算机的发明 ，这种方法作为一种独立的方法被提出来，并首先在核武器的试验与研制中得到了应用。蒙特卡罗方法是一种计算方法，但与一般数值计算方法有很大区别。它是以概率统计理论为基础的一种方法。由于蒙特卡罗方法能够比较逼真地描述事物的特点及物理实验过程，解决一些数值方法难以解决的问题，因而该方法的应用领域日趋广泛。 -Monte Carlo method known as random or statistical skills test method. More than half a century, the development of science and technology and the invention of the electronic computer, this method as an independent method was raised and the first nuclear test and research has been applied. The Monte Carlo method is a calculated, but with the general numerical method a great difference. It was based on the theory of probability and statistics-based approach. As the Monte Carlo method can vividly describe things and the physical characteristics of the experimental process, numerical methods to solve some difficult problems, the result of the increasingly extensive application areas.
