The Dragon, the Blade and the Thread

為了解決this that these thos的問題,作者Samson, Donald/ Agee, Adam 這樣論述:

Prince Corin has more freedom than most youngsters his age, but he feels restrained by his family's expectations. He hates being trained how to handle a sword or spending time with his mother selling vegetables at the market. He even resents the time he has to spend caring Star, the kingdom's precio

us Luck Dragon. He wants to be left alone to follow his own interests. He even strikes up a relationship with a marketplace magician, whom his mother tells him he cannot trust and must stay away from. Then Corin's cousin Elinor comes to live with them, following the death of her parents. This turns

his world upside down. Elinor does not trust Corin. He had played practical jokes on her when they were younger, and she is not even ready to believe that he has the ability to speak with the dragon. Not many days after arriving, Elinor is kidnapped and Star takes Corin to the rescue, forcing him to

access sides of himself that he is reluctant to acknowledge. This draws the cousins closer, but they still continue to bicker. Before the Queen has a chance to present Elinor at court, she overhears two men plotting against the crown who then threaten her if she ever speaks of what she has heard. C

orin dismisses her suspicions, since one of the men was captain of army, whose loyalty is unquestioned. To keep Elinor safely out of the way, Star suggests that she join Corin for their daily training exercises by the river. To Corin's surprise, Elinor takes to the training and already has skills th

at surpass his. This motivates him to try harder, and the two add competition at arms to their growing rivalry. It is not long before Elinor is able to convince Corin that her suspicions are founded. All this time, both Corin and Elinor have continued their relationship with the marketplace magician

. Corin's parents warn him to stay away, suspecting that he may be behind the mysterious malaise that has overcome Star. Harsh words pass between father and son, both expressing sentiments they later regret speaking. The cousins are split, not wanting to be disobedient, and at the same time, trustin

g that the magician can help them. One day after market, the cousins are ambushed and Elinor is again carried away and stowed in the hold of a riverboat. Corin tracks the kidnappers down and in the deep of night rescues his cousin. In their flight, they are rescued from pursuit in an unexpected enco

unter with the marketplace magician. The magician, Thos, introduces them to his community of free spirits, the Enclave. He warns the cousins to keep their true identity secret, since the royal family is not popular among the residents. Their return to Gladur Nock is delayed because Elinor had injure

d her ankle during their escape. While staying in the Enclave, Corin's eyes are opened to the mistrust and animosity his family and even Star are viewed by those who consider themselves disenfranchised. Thos shows him his workshops where the people process a flammable oil called naphtha. Corin begin

s to understand the needs of these people and sympathizes with their goals. Thos is called away, and tells the cousins to remain until he summons them. When the message arrives, Corin realizes he must take action to derail the plot against his family and reconcile the differences with the alienated

population. Before leaving, he reveals his true identity and strikes a shaky bargain with the leaders of the Enclave. In the meantime, the king has vanished, searching for the lost cousins. The queen, in desperation, accepts an offering of peace from to the king to the north with whom they have long

been at war. Together with her personal guard, she travels to a peace summit. However, once arrived, she is taken captive and told they will burn her as a witch. Unbeknownst to her, the king sits in the dungeon, captured while searching for their son. Elinor and Corin arrive at this very stronghold

, and the king rejoices that he can now destroy them all. Knowing that the dragon will fly to their rescue, he has devised a tar pit in which Star is entrapped and slowly engulfed. Corin, Elinor and the king, however, escape and arm themselves. They fight to reach the queen who is bound to a stake t

o be burned. They fight against impossible odds, when suddenly an army from the Enclave arrives and utilizes the naphtha they produce to fight against the larger force. Yet even with their flame-throwers, they are no match against the king's army. At the last moment, Michael's captain arrives leadin

g a force that takes the field. Corin saves Star from a tarry end, and after proving himself on the field of battle, using his skills at sewing to attend to the wounded. He had been under the physician's guidance all along. Thos is revealed to be Aga, who had appeared to keep an eye on the young pri

nce and the dragon. He convinces the king to let Corin travel with him and learn about the wider world. Elinor discovers an uncanny connection to Star and happily remains behind to be his caretaker.

Uncertainties of Geometrical and Mechanical Properties of Heterogeneous Media and Discontinuous Rock Masses

為了解決this that these thos的問題,作者盧育辰 這樣論述:

本文分別提出異質性介質(heterogeneous media)及不連續岩體(discontinuous rock mass)的體積比(volumetric fraction)、裂隙程度(fracture intensity)及力學性質不確定性之解析解及數值解,並根據統計定理得知幾何及力學性質之關係。由體積比或裂隙程度引致之不確定性可根據幾何模型量測的不確定性推導得知。針對異質性介質(併構岩、混凝土等)量測體積比之不確定性,本文利用表徵單元(representative volume element, RVE)作為統計推論模型,分別得到以一維及二維量測體積比不確定性之解析解;外方內圓的表徵單

元被應用於二維等向異質性介質之形貌,而外平行四邊形內橢圓的表徵單元被應用於二維異向異質性介質之形貌,另外方內球的表徵單元應用於三維等向異質性介質之形貌。此外,本文分別撰寫二維及三維異質性介質模擬一維及二維量測體積比的不確定性,提出數值解並驗證解析解之正確性。此數值程式應用週期性邊界(periodic boundaries),可消弭邊界效應及精準控制異質性介質之體積比。針對不連續岩體(裂隙岩體)量測裂隙程度之不確定性,本文利用柏松分配(Poisson distribution)模型分別推得一維、二維及三維裂隙程度之不確定性解析解。此外,本文利用自行撰寫之離散裂隙網絡(discrete fract

ure network, DFN)及市售離散裂隙網絡軟體FracMan模擬一維、二維及三維裂隙程度之不確定性數值解,並驗證解析解之結果。由體積比及裂隙程度引致力學性質之不確定性,可將體積比及裂隙程度的不確定性代入至常態隨機變數及幾何力學關係式中得知。有關異質性介質的幾何及力學性質關係式可由微觀力學模式(micro-mechanical models)或顆粒流軟體(Particle Flow Code, PFC)模擬決定,而不連續岩體的幾何及力學性質關係式則由合成岩體(synthetic rock mass, SRM = DFN + PFC)模型模擬得知。由塊體或裂隙排列引致之力學性質之不確定性

係由一系列參數研究得知。根據統計推導,異質性介質或裂隙岩體力學性質的不確定性可分別由「體積比及裂隙程度引致力學性質之不確定性」及「塊體或裂隙排列引致力學性質之不確定性」計算得到,此結果業經數值驗證。另本文在每章節末,提供一至數個實例操作及案例示範如何使用本文提出之幾何及力學性質不確定性之解。

比較多目標最佳化方法於靜壓軸承之設計

為了解決this that these thos的問題,作者許芷柔 這樣論述:

現實的工程設計問題常存在兩個或兩個以上的設計目標,須使用不同於單目標最佳化的方法以求得最佳的設計參數,此類問題需以多目標最佳化的方法來解決,以提高得到最佳設計結果的效率。本論文的主要目的為比較三種多目標最佳化方法之優劣於多孔洞氣體軸承的設計,研究中採用的二個最佳化目標為提升氣體軸承的剛性及降低供給氣體的消耗量,而軸承的模型中共有四個設計變數會影響這二個設計目標。為使最佳化設計及分析更加有效率,本研究結合MATLAB即時繪圖和Fortran計算快速這兩種計算平台的優點,不但可以即時監控搜尋最佳設計參數的過程,且能減少執行最佳化設計的時間。 本研究以粒子群演算法(Particle Sw

arm Optimization, PSO)進行氣體軸承多目標最佳化設計,並與文獻[2]中使用多目標基因演算法(Multiobjective Genetic Algorithm, MOGA)的結果比較,結果顯示本研究採用的三種多目標PSO方法(即MOPSO1-3)均能比MOGA在較短的計算時間內得到較佳的設計結果,其中又以MOPSO3所得到的結果最佳。MOPSO3不但能改善最佳值的粒子於移動過程中可能因PSO移動機制而移離最佳位置之情形,且能使帕雷托前緣(Pareto front)的分佈更加廣泛,並且有三分之二部份的帕雷托前緣和理想最佳化結果相近。
