In addition, this construction method also takes a city's overpass as the research object of this case. Through the analysis and study of generator function, the application of generator is introduced in the process of variable section bridge modeling.

Comparing with other indoor location methods, ultra-wide band (UWB)indoor location technology has the advantages of strong anti-multipath interference ability and signal penetration ability. But, when this method faces large obstacles or metal obstacles, non line of sight (NLOS) will still occur. Indoor location system is a part of our project \"Home Care System for The Elderly\". The NLOS of Indoor location system reduces the reliability of \"Home Care System for The Elderly\". In order to improve the accuracy of location and efficiency of operation, an NLOS detection method based on k-nearest neighbors (KNN) algorithm is proposed. This algorithm modeled the training samples to find the K value with the highest recognition accuracy. The experimental results show that The NLOS detection accuracy of this method is 78% in the simulated apartment scene. With the same number of samples, the accuracy of the widely used Convolutional Neural Networks (CNN) algorithm is 67%.
