This paper is an attempt to look up the life of Guanyu who was a sainted warrior of Shu Han(蜀漢) and later, was revered as God, especially focusing on the Political perspective of Chinese Dynasty. People represented Guanyu as the general during the Wei Jin Southern and Northern Dynasties(魏晉南北朝), however, throughout the Su-Dang Dynasty(隋唐), Guanyu was Honored in the Wuchengwangmiao(武成王廟) then, was promoted from Hou(侯) to Gong(公), Gong(公) to King(王) in the Song-Yuan Dynasty(宋元). In the Ming-Qing Dynasty(明 淸) when the deification of Guanyu was proceeded most positively, he became a Di(帝) over a King and was endowed with the power over the Three Worlds(三界). He had an influence on nobility as well as the people in Folkbelief over Moral Spirits, and consequently rose through the ranks to become the spiritual guardian. The rulers gave him various names(封號) celebrating the life and work of Guanyu, In fact, they showed interests in the Belief of Guanyu as they attempted to establish an ideological base for the solution of the national disaster and maintenance of feudal system which came to the fore along with the reinforcement for emperor's power.

This paper presupposes that the reason for the development of Guanyu's anthropolatry as a cultural phenomenon is derived from, along with Guanyu's loyalism and valor, the people's physiological effects longing for the emergence of a hero, and is closely linked with religious activities to provide the justification of their belief system. Based on this, the purpose of this paper is to study how major religions that is, Confucianism, Buddhism and Taoism take the courses of Guanyu's anthropolatry to their religious advantage and how Guanyu-god is applied to roots in Confucianism, Buddhism and Taoism. In Buddhism, it succeeded in the settlement by upgrading it to jialan-shen that guarded the Buddhist temple, while in Taoism, it was used as a guardian of the san-jie-fu-mo-da-di that chased the almighty devil and deviated from the disaster and suffering. In Confucianism, it was connected to Guanyu's Confucian-commander image to that of chun-qiu-da-yi of kongzi. That is, by symbolizing Guanyu as God of Martial Power and War depending on the country, it was used as a means of governance to establish rules and order.

Income distribution is a major concern in economic theory. In regional economics, it is often of interest to compare income distributions in different regions. Traditional methods often compare the income inequality of different regions by assuming parametric forms of the income distributions, or using summary statistics like the Gini coefficient. In this paper, we propose a nonparametric procedure to test for heterogeneity in income distributions among different regions, and a K-means clustering procedure for clustering income distributions based on energy distance. In simulation studies, it is shown that the energy distance based method has competitive results with other common methods in hypothesis testing, and the energy distance based clustering method performs well in the clustering problem. The proposed approaches are applied in analyzing data from China Health and Nutrition Survey 2011. The results indicate that there are significant differences among income distributions of the 12 provinces in the dataset. After applying a 4-means clustering algorithm, we obtained the clustering results of the income distributions in the 12 provinces.

This study collected and intensively analyzed the works and remains in Namwon(南原) province by Liu Ting(劉綎) of Ming Dynasty during the Imjin War (the Japanese invasion in 1592-1598; 壬辰倭亂). Liu Ting engraved characters on the rocks as passing by the Yeowon hill(女院峙) twice. A local official of Namwon built a memorial stone at the guest residence of Namwon district to appreciate the contribution of Liu Ting to care for the local people. During the second Japanese invasion in 1597-1598(丁酉再亂), Liu Ting often climbed up the Yongdu pavilion(龍頭亭) located at Mt. Yongtu(龍鬪山) and fell in love with the splendid scenery while enjoying fishing at Jogi(釣磯). Immediately after the war, Liu Ting renovated the Guanwang Shrine(關王廟) in Namwon and built the memorial stone claiming that he defeated the Japanese army with the divine power from Guanyu(關羽).

Density-based outlier detection is one of the hot issues in data mining. A point is determined as outlier on basis of the density of points near them. The existing density-based detection algorithms have high time complexity, in order to reduce the time complexity, a new outlier detection algorithm DODMD (Density-based Outlier Detection in Multidimensional Datasets) is proposed. Firstly, on the basis of ZH-tree, the concept of micro-cluster is introduced. Each leaf node is regarded as a micro-cluster, and the micro-cluster is calculated to achieve the purpose of batch filtering. In order to obtain n sets of approximate outliers quickly, a greedy method is used to calculate the boundary of LOF and mark the minimum value as LOF_min. Secondly, the outliers can filtered out by LOF_min, the real outliers are calculated, and then the result set is updated to make the boundary closer. Finally, the accuracy and efficiency of DODMD algorithm are verified on real dataset and synthetic dataset respectively.

Meeting the touchdown point (TDP) target box is one of the challenges during catenary riser installation, especially for deep water or ultra-deep water riser systems. TDP location mismatch compared to the design can result in variation of riser configuration, additional hang-off misalignment, and extra bending loads going into the hang-off porch. A good understanding of the key installation parameters can help to minimize this mismatch, and ensure that the riser global response meets the design criteria. This paper focuses on investigating the potential factors that may affect the touchdown point location, and addressing the challenges both in the design stage and during installation campaign. Conventionally, the vessel offset and current are the most critical factors which may affect the TDP movement during installation. With the offshore exploration going deeper and deeper in the sea (up to 10,000ft), other sources such as the seabed slope and seabed soil stiffness are playing an important role as well. The impacts of potential sources are quantified through case studies for steel catenary riser (SCR) and lazy wave steel catenary riser (LWSCR) in deep water application. Investigations through both theoretical study and numerical validation are carried out. Furthermore, design recommendations are provided during execution phase for the TDP mismatch condition to ensure the integrity of the riser system.

Coronary artery disease (CAD) is a major cause of death in the world. As a non-invasive imaging modality, computed tomography angiography (CTA) is now usually used in clinical practice for CAD diagnosis. Precise quantification of coronary stenosis is of great interest for diagnosis and treatment planning. In this paper, a novel cluster method based on a Modified Student's t-Mixture Model is applied to separate the region of vessel lumen from other tissues. Then, the area of the vessel lumen in each slice is computed and the estimated value of it is fitted with a curve. Finally, the location and the level of the most stenoses are captured by comparing the calculated and fitted areas of the vessel. The proposed method has been applied to 17 clinical CTA datasets and the results have been compared with reference standard degrees of stenosis defined by an expert. The results of the experiment indicate that the proposed method can accurately quantify the stenosis of the coronary artery in CTA.

The modular multilevel converter (MMC) has become a promising topology for high-voltage direct current (HVDC) transmission systems. To control a MMC system properly, the ac-side current, circulating current and submodule (SM) capacitor voltage are taken into consideration. This paper proposes a low-computation indirect model predictive control (IMPC) strategy that takes advantages of the conventional MPC and has no weighting factors. The cost function and duty cycle are introduced to minimize the tracking error of the ac-side current and to eliminate the circulating current. An optimized merge sort (OMS) algorithm is applied to keep the SM capacitor voltages balanced. The proposed IMPC strategy effectively reduces the controller complexity and computational burden. In this paper, a discrete-time mathematical model of a MMC system is developed and the duty ratio of switching state is designed. In addition, a simulation of an eleven-level MMC system based on MATLAB/Simulink and a five-level experimental setup are built to evaluate the feasibility and performance of the proposed low-computation IMPC strategy.

It is significant to predict the performance degradation of complex electromechanical systems. Among the existing performance degradation prediction models, belief rule base (BRB) is a model that deal with quantitative data and qualitative information with uncertainty. However, when analyzing dynamic systems where observable indicators change frequently over time and working conditions, the traditional belief rule base (BRB) can not adapt to frequent changes in working conditions, such as the prediction of aeroengine performance degradation considering working condition. For the sake of settling this problem, this paper puts forward a new hidden belief rule base (HBRB) prediction method, in which the performance of aeroengines is regarded as hidden behavior, and operating conditions are used as observable indicators of the HBRB model to describe the hidden behavior to solve the problem of performance degradation prediction under different times and operating conditions. The performance degradation prediction case study of turbofan aeroengine simulation experiments proves the advantages of HBRB model, and the results testify the effectiveness and practicability of this method. Furthermore, it is compared with other advanced forecasting methods. The results testify this model can generate better predictions in aspects of accuracy and interpretability.
