Water Rights and Policies in the United States: A State by State Analysis

為了解決Groundwater的問題，作者Porter, Charles R., Jr. 這樣論述：

As water becomes ever more important in a rapidly growing United States challenged by lessening firm-yield water reliability, the public needs to understand the myriads of quite different state-by-state water policies. States share surface water and groundwater sources that relate to each other c

onjunctively. Texans for example, should understand New Mexico water ownership and state policies because they share surface water and groundwater sources. Californians should understand Nevada’s water policies for the same reasons. Above all else, the people of the United States must realize that a

water policy in one state can drastically impact water availability in neighboring states. Although the federal government has supra-legal authority over some state water policies and acts as the ultimate arbiter of interstate disputes, no one current book exists that explains the complicated relat

ionships between state water policies with an analysis of federal water policies. Water Rights and Polices in the United States is a one-stop resource providing a state-by-state analysis of water ownership, regulatory agencies, and water polices. It explains the complicated relationships between sta

te water policies and provides an analysis of federal water polices. How we manage these policies is of utmost importance to all Americans.

應用HHT於水位自動資料檢核系統

為了解決Groundwater的問題，作者蕭武賢 這樣論述：

臺灣地區河川水位變化頻繁，由於水位資料需要現地監測取得，但現地可能有各種狀況，如儀器故障、傳輸異常及人為疏失等干擾，皆會影響其數據真實性，因此原始資料必須先執行品管檢核程序，將異常且不合理數據過濾排除，以利提供於水文研究分析較準確之數據使用。本研究所建立之自動化檢核程序利用希爾伯特-黃轉換(Hilbert-Huang ransform, HHT)達到檢核之目標，此方法為黃鍔博士於2009年所提出之時頻分析法，將訊號進行拆解並且分析各自瞬時頻率與振幅能量之相互關係。首先使用整體經驗模態分解法(Ensemble Empirical Mode Decomposition, EEMD)進行拆解，瞭解

此訊號之組成要素因子，為有限個本質模態函數(Intrinsic Mode Functions, IMF)以及一個剩餘函數(residual)，為達到辨識出異常值特徵，因此需最大程度表現出水位變化之突波(spike)與異常值的IMF分量，故而僅選擇第一個IMF分量進行希爾博伯特轉換(Hilbert Transform, HT)，轉換後可取得其時間-振幅能量關係圖，觀察該分量之振幅起伏對應真實水位情況，可知道其異常值之振幅數值，當振幅數值越大就可能有異常值出現，反之則為趨向合理情況，藉由觀察各點之振幅數值大小，設定一閥值作為過濾異常值之判斷依據，將超過閥值的點位過濾並排除，而選定閥值大小能控制品管

檢核結果，故可調節不同閥值進一步左右篩選結果，以此達到自動化檢核水位資料之目的。本研究使用傳統人工品管檢核作為標準取得該閥值，利用此閥值完成自動化檢核之最終篩選依據。為降低人工檢核時之人為因子影響結果，故而選定以與人工品管檢核結果約95%相似，若較保守設定其閥值，可盡量避免破壞原始數據之真實物理意義，篩選結束後仍可使用人工檢查確保其數據正確。依據品管檢核的結果得知，可發現自動化檢核可篩選出幾乎全部的異常值，將人工觀察到之明顯突波異常值，能盡量過濾剃除，並且對篩選結果以線性內插進行資料補遺，讓水位資料以連續且完整狀態呈現。自動化檢核程序相比人工檢核程序，能縮短檢核時間且節省檢核人員精力，提供更為

穩定運作之水位品管檢核程序，亦可更為靈活地根據不同篩選需求調整過濾門檻。

可選擇性的線性分類器方法應用於行政執行的經濟弱勢族群之判定─以某行政執行分署為例

為了解決Groundwater的問題，作者林在一 這樣論述：

「執行有愛」與「公義無礙」是行政執行機關的施政理念。然而，在執行行政案件時，若能有效且準確的判斷經濟弱勢義務人，並予以分流不同的執行方法與對應的援助，是行政機關一直以來很重視的議題。本研究首先建構出一個可選擇最佳分類方法的結構程序，即以重複模擬抽樣的方式，觀察各分類方法在準確度比較上的成功率，以作為選定分類方法的準則。並透過收集歷年行政執行的案件與義務人的資料，先以定義相近且常用的線性判別分析 (linear discriminant analysis, LDA) 及支撐向量機(support vector machine, SVM) 來做為二選一的評估。研究結果顯示SVM具有較佳的準確能力

，且在穩態資料下，預測的驗證結果也有較好的表現。本研究雖僅比較兩種線性分類方法，未來亦可以此研究方法架構下，進一步探討多種分類方法評估的比較，讓資料分析人員可依據不同資料結構的案例，選擇出最適分類方法，並獲得更佳的判別結果。
