The evaluation of high occupancy vehicle lanes on Sun Yat-Sen freeway in Taiwan
No full text[[abstract]]This study proposes a methodological framework to incorporate latent factors, including direct and indirect perceptions, as the explanatory variables in a discrete choice models using revealed preference and stated preference data sets. The methodology requires the estimation of a model system comprising of a discrete choice model and the structural and measurement equations of a latent variable model. The application involves the evaluation of responses to the new high occupancy vehicle (HOV) lanes on the Sun Yat-Sen Freeway in Taiwan. The results obtained from this study provide valuable insights into the planning and assessment of HOV lanes.[[note]]SC

Dynamic commuter departure time choice under uncertainty
No full text[[abstract]]The reference point hypothesis of prospect theory is applied to commuters' departure time decision-making and to obtain a better understanding of how commuters use arrival time information in daily departure time choice. There are two reference points defined in this study: the earliest acceptable arrival time and the work starting time for a given commuter. An arrival is defined as an early-side arrival if the arrival time is earlier than his/her preferred arrival time, and a late-side arrival otherwise. A gain occurs when a commuter experiences an arrival time that is between his/her earliest acceptable arrival time and work starting time; this is assumed to enhance the likelihood of choosing the same departure time. Similarly, a loss is observed when the commuter experiences an arrival time which is outside that range; this is assumed to reduce the likelihood of choosing that departure time. The empirical results indicate that around 20% of commuters are likely to switch their departure times and routes and most of commuters experience gains, and that preferred arrival times of commuters tend to be near their work starting times. Most importantly, it is shown that, consistent with prospect theory, commuters react asymmetrically to gains and losses. (C) 2008 Elsevier Ltd. All rights reserved.[[note]]SC

Macroeconomic factors' influences on consumer price level in South Korea
No full text全球央行最近在利率調整方面的動作頻頻，顯示「通貨膨脹」隱憂，已取代經濟復甦，成為央行最主要的課題。由於物價水準的波動對全球經濟的影響甚劇，故本文欲以物價水準做為研究的主題，並以經濟情勢與台灣相似的南韓為實
證對象。
本文以南韓於1987年1月到2005年4月的月資料為主，觀察南韓匯率、利率、貨幣供給、實質所得、國際收支餘額、物價六者之間是否具有共整合關係，採用Johansen共整合檢定法來檢測，檢定變數間長期均衡關係。根據本文實證結果，主要結論為如下。
在5%、1%的顯著水準下，Johansen 的最大特徵根檢定統計量指出此六個變數存在一組共整合關係。南韓的國內利率、匯率、貨幣供給、實質國內生產毛額，與南韓之物價水準成正向關係，此結論與本文第三章的預期結果符合。而國際收支餘額與物價水準為正向關係，我們推論，此結果可能是因南韓在匯率制度方面採取管制而造成。國際收支餘額增加時，為維持匯率致使貨幣供給增加而對物價所造成的影響，大於實質所得增加對物價的影響，使得南韓的物價水準上升。
政府在擬定相關政策時，應密切觀察不同因素對物價水準所可能產生的衝擊性，以便制訂適當的政策。而中央銀行在維持物價水準的過程中，匯率政策又該扮演何種角色？是否會因匯率政策改變了貨幣供給，進而影響了物價水準與國內經濟。這些都是值得我們深入思考的問題。The interest rate has been frequently adjusted recently in many countries. It shows that the worries about inflation, which have already replaced economic recovery, have become the main economic subject. Because of the dramatic impact on global economy, we discuss the price level in South Korea, which its economic situation is similar to Taiwan’s.
Adopting Johansen cointegration test, we used the monthly data from January 1987 to April 2005 and observed that whether the long-run relation existed between the price level and relevant macroeconomic factors. The empirical result is as follows.
According to the result of Max-Eigenvalue test, one cointegration existed between these variables. When the interest rate and exchange rate raised, the money supply increased, and the real GDP decreased, the price level in South Korea raised. The results fit in with what we anticipated in Chapter Three of this thesis. The price level is positive to the balance of payment. We inferred that it might be caused by that the government intervened in the exchange rate system. When the balance of payment increased, the government bought the foreign currency to prevent the currency from appreciation and the money supply increased. As the result, the price level raised.
When the government makes the relevant policies, it should be observed that each factor impacts the price level closely. When the Government wants to keep the price level steady, what kind of role should the exchange rate policy play? When the money supply fluctuates because of the intervention to exchange rate, how do the price-level and the domestic economy be influenced? These are worth considering carefully.目 錄 4

Experimental and numerical study of evolving tributary-dammed lakes
No full text本篇論文結合實驗與數值計算模擬支流大量供砂下河床變化之情形。實驗渠道為長312公分，寬1.2公分的小尺度實驗，以上游流量與供砂量達動床平衡作為初始條件，在渠道中游提供三種供砂量，並藉此使河川形貌動力產生不同的現象，經由影像處理自動捕捉底床與水面的變化，再透過淺水方程式 (Shallow water equation)，艾克納方程式 (Exner equation)以及邊界特徵結構分析 (Eigenstructure analysis)，並根據HLL與LHLL和有限體積法建立一維雙層地貌數值模式。本文中亦延伸該模式至二階精度以探討不同階數次序的模擬差異，最後透過實驗結果以檢核數值模擬的表現。In this study, one-dimension laboratory experiments and mathematical descriptions are used to perform the evolution of river influenced by tributary sediment influx. For the small-scale laboratory experiments (312cm long and 1.2 cm width), three tests are conducted to describe the differences of the morphodynamic response of the river bed: tributary-induced cuspate aggradation, tributary-dammed lake and water blocking dam. To simulate the phenomena, the numerical model dividing the flow into two layers, a pure water layer and a sediment transport layer, adopts shallow water equations that govern the evolution of each interface: with appropriate boundaries which depend on characteristics equations. According to the HLL, LHLL scheme and finite volume numerical solver, the model can be extended to both first-order and second-order accurate version. The proposed methods are applied to the laboratory experiments in order to examine the performance of the one dimensional geomorphological model.口試委員會審定書 #

An Efficient Algorithm for Mining Closed Frequent Inter-transaction Itemsets
No full text跨交易關聯規則可代表不同交易中項目間的關係，而近年來有愈來愈多相關的探勘演算法被提出，然而這些演算法會產生相當多的跨交易頻繁項目集合。找尋封閉性跨交易頻繁項目集合可使探勘的過程更有效率。
因此，在本篇論文中我們提出了一個探勘演算法叫「ICMiner」，以找尋封閉性跨交易頻繁項目集合。我們的方法可分為兩個階段。第一階段，將原始的資料庫轉換成領域屬性集合，使得每一個頻繁項目的領域屬性形成一個集合。第二階段，利用ID-tree去列舉出所有的封閉性跨交易頻繁項目集合。藉由ID-tree進行資料探勘，我們可以避免產生候選樣式及重複計算支持度。因此，ICMiner可大幅提升了找尋跨交易頻繁項目集合的效率。實驗結果顯示，ICMiner比FITI與ClosedPROWL快上幾十倍。Many algorithms have been proposed recently for finding inter-transaction association rules, which represent the relationships among itemsets across different transactions. Since numerous frequent inter-transaction itemsets will be generated, mining closed frequent inter-transaction itemsets can speed up the mining process.
Therefore, in this thesis, we propose an algorithm, ICMiner (Inter-transaction Closed patterns Miner), to mine closed frequent inter-transaction itemsets. Our proposed algorithm consists of two phases. First, we convert the original transaction database into a set of domain attributes, datset, for each frequent item. Second, we enumerate closed frequent inter-transaction itemsets by using an itemset-datset tree, ID-tree. Mining closed frequent inter-transaction itemsets with an ID-tree, we can avoid costly candidate generation and repeatedly support counting. The experimental results show that our proposed algorithm outperforms the FITI and ClosedPROWL algorithms by one order of magnitude.Table of Contents i
