In this study, the rainfall, yield distributed water and water sold¡K¡Ketc., 41 parameters from 1974 to 2006 were assessed the reasonable water rate adjustment. At first, 41 parameters were analyzed by SPSS software for descriptive statistiics, Pearson relational analyzing the data of input/output of correlation with a £^ value and screening of variables. Then, actual water price and designed water price will be the out variable. Try to find the optimal neural network structure and try to analyze and produce the water pricing structure. The results show that the unit profit/loss from sales of Taiwan Water Corporation(TWC) for 33 years from 1974-2006, there are 11 years positive and 22 years negative, especially the past 20 years only on 1990, 2003, and 2005 are positive, the others are negative. TWC had not obtained the reasonable profit. Because since 1996, the range of return on water investment and return on equity are -0.98%-0.1% and 0.07%-0.52% lower than legal standard 5%, respectively. Moreover, the rate of water price for the household consumption expenditure from 0.791% in 1982 decrease to 0.39% in 2006. To compare with the rational level for World Health Organization asserted 2%-4%. The water price of Taiwan is only 10%-20% of the level. Furthermore, the rate of water price for disposable income is from 0.606% in 1982 drops to 0.305% in 2006 and the rate for GDP is 0.18%-0.2% in the past 10 years. In this study, the actual water price and designed water price were set as output parameter. The input variables divide to 29 and 19 units and hidden layer is set 1 or 2 layers. BPN(Back-Propagation Network) were through trial and error method to training, testing, and production the output. The training results show that 19 variables is better than 29 variables while we use actual water price and 2 hidden layers is better than 1 layer. However, when we use designed water price, 19 variables is still better than 29 variables, but 1 hidden layer is better than 2 hidden layers. The best production of water price of 1981, 1991, 1996, 2001, 2006 are 9.20, 12.62, 20.09, 23.07, 24.39 NT$, respectively. The values are close to designed water price 9.0, 12.6, 19.1, 22.2, 25.5 NT$. Whether we use 29 or 19 variables, 1 or 2 hidden layers, the training results indicated that the water price designed by household consumption expenditure is better than actual water price. Thus, the historical water price did not correspond to real operating costs for TWC in the past. In addition, the designed water price in this research can more correlated with the operating cost and efficiency of TWC.

Traffic incidents are non-recurring events that can cause a temporary reduction in roadway capacity. They have been recognized as a major contributor to traffic congestion on our national highway systems. To alleviate their impacts on capacity, automatic incident detection (AID) has been applied as an incident management strategy to reduce the total incident duration. AID relies on an algorithm to identify the occurrence of incidents by analyzing real-time traffic data collected from surveillance detectors. Significant research has been performed to develop AID algorithms for incident detection on freeways; however, similar research on major arterial streets remains largely at the initial stage of development and testing. This dissertation research aims to identify design strategies for the deployment of an Artificial Neural Network (ANN) based AID algorithm for major arterial streets. A section of the US-1 corridor in Miami-Dade County, Florida was coded in the CORSIM microscopic simulation model to generate data for both model calibration and validation. To better capture the relationship between the traffic data and the corresponding incident status, Discrete Wavelet Transform (DWT) and data normalization were applied to the simulated data. Multiple ANN models were then developed for different detector configurations, historical data usage, and the selection of traffic flow parameters. To assess the performance of different design alternatives, the model outputs were compared based on both detection rate (DR) and false alarm rate (FAR). The results show that the best models were able to achieve a high DR of between 90% and 95%, a mean time to detect (MTTD) of 55-85 seconds, and a FAR below 4%. The results also show that a detector configuration including only the mid-block and upstream detectors performs almost as well as one that also includes a downstream detector. In addition, DWT was found to be able to improve model performance, and the use of historical data from previous time cycles improved the detection rate. Speed was found to have the most significant impact on the detection rate, while volume was found to contribute the least. The results from this research provide useful insights on the design of AID for arterial street applications.

This psychobiography used the framework of Individual Psychology to examine the life style development of the Honorable Ann Richards in order to provide insight into the creation of a life style by a successful, contemporary female leader. This single case study utilized a qualitative/phenomenological research methodology to examine from Ms. Richards' point of view the manner in which a highly visible and well-known individual created her particular style of life.
