On the basis of Venigalla\'s work,we adopted two path-based algorithms, namely,gradient projection algorithm and disaggregated simplicial decomposition algorithm to solve nonadditive path cost traffic assignment problem under different engine operating modes.We compared the above two algorithms in a network example which showed that compared with the traditional Frank-Wolfe algorithm, the two path-based algorithms had a more quicker convergency while getting optimal solution,and it can obtain a satisfying solution in most cases.

2在Venigalla等人研究工作的基础上，分别采用基于路径的梯度投影算法(gradient projection，GP)和基于路径的非集计的单纯分解算法(disaggregated simplicial decomposition，DSD)来求解考虑不同发动机启动模式下，具有非可加路径费用的交通分配问题，在实例计算中比较了这两种算法的计算性能。

An accelerated acoustic echo cancellation algorithm is proposed in this paper based on Parallel Subgradient Projection technique.

摘要该文在并行次梯度投影技术(Parallel Subgradient Projection，PSP)的基础上，提出一种加速回波抵消算法。

Furthermore, we solve the user equilibrium problem by gradient projection method to obtain some additional path-based information. Since true OD trip demands are unknown, we conduct OD demand estimation and OD demand covering rate verification by the least square estimator.

在求解使用者均衡之交通量指派问题上，透过梯度投影法(Gradient projection， GP)求解，并获得以路径为基础的相关资讯；在流量倒推旅次起迄量的课题上，由於真实OD量未知，故使用基本的最小平方估计量，进行旅次起迄需求涵盖量的推估与检验。

The anteroposterior projectionof the foot, utilized to examine the foot disease in the past was referred as to the freely-stressed method. However, most of the patients on suspicion of Hallux Valgus get pains while standing with weight-bearing. Additionally, the patients' real conditions can not be diagnosed without standing. it is helpful for us to apply both the foot weight-bearing and the foot non weight-bearing so as to probe the individual difference between the HVA and the IMA 1(superscript * intermetatarsal angle and further to provide the informative resources concerning the assessment of performing surgery operation. The study include 40 patients who we having Hallux Valgus of different degree, The findings have revealed the significant difference among 40 patients after the method-weight-bearing AP of the foot projection given.

过去一般常用诊断足部疾病的足部摄影(anteroposterior projection of the foot； AP projection of the foot)是指未施加压於病人足部的拍摄方法，然而多大脚趾外翻的病患常於站负重时感觉疼痛舒服，而未负重摄影却无法呈现出病人站时的真实态，因此我们用足部前后位负重摄影(weight-bearing AP projection of the foot)与足部未负重摄影(non weight-bearing AP projection of the foot)的影像比较其大脚趾外翻角(Hallux valgus angle， HVA)及第一跖骨间的角1(上标 st intermetatarsal angle， IMA的差，进而提供外科手术的估评。
