Monotone Pieces Analysis for Qualitative Modeling
It is a crucial task to build qualitative models of industrial applications for model-based diagnosis. A Model Abstraction procedure is designed to automatically transform a quantitative model into qualitative model. If the data is monotone, the behavior can be easily abstracted using the corners of the bounding rectangle. Hence, many existing model abstraction approaches rely on monotonicity. But it is not a trivial problem to robustly detect monotone pieces from scattered data obtained by numerical simulation or experiments. This paper introduces an approach based on scale-dependent monotonicity: the notion that monotonicity can be defined relative to a scale. Real-valued functions defined on a finite set of reals e.g. simulation results, can be partitioned into quasi-monotone segments. The end points for the monotone segments are used as the initial set of landmarks for qualitative model abstraction. The qualitative model abstraction works as an iteratively refining process starting from the initial landmarks. The monotonicity analysis presented here can be used in constructing many other kinds of qualitative models; it is robust and computationally efficient
Scale-Based Monotonicity Analysis in Qualitative Modelling with Flat Segments
Qualitative models are often more suitable than classical quantitative models in tasks such as Model-based Diagnosis (MBD), explaining system behavior, and designing novel devices from first principles. Monotonicity is an important feature to leverage when constructing qualitative models. Detecting monotonic pieces robustly and efficiently from sensor or simulation data remains an open problem. This paper presents scale-based monotonicity: the notion that monotonicity can be defined relative to a scale. Real-valued functions defined on a finite set of reals e.g. sensor data or simulation results, can be partitioned into quasi-monotonic segments, i.e. segments monotonic with respect to a scale, in linear time. A novel segmentation algorithm is introduced along with a scale-based definition of "flatness"
A Study on the Changes of Gender Morality in China: Centered on the Male Experience in the "Love Letter" Incident (1900-1930)
In the 20th century, China was an era of significant social changes, experiencing the impact of abolishing old and establishing new in politics, economy, culture, and other aspects. In terms of sexual morality, traditional sexual morality was criticized by Chinese youth and intellectuals, while new sexual morality was disseminated among young people. The love letter incident that occurred in such a social context is a representative event of young men and women actively breaking traditional sexual morality and constructing new sexual morality. This article takes two love letter events that occurred in China in the early 20th century and the 1920s as research objects, focusing on the experiences of young men in the love letter events. Using the method of seeking differences, it first clarifies the thoughts and expressions of young men on the issue of love in the love letter text. Secondly, it analyzes the views and debates of public power and social elites on the events in the love letter events, thereby revealing the end of the old sexual morality and the development of new sexual morality in modern China. In the two love letter events, the content of the young man\u27s love letters both demonstrated his longing for new sexual morality. Qu Jiang faced criticism, while Qiu Gongyi received sympathy. The different experiences of the male protagonist in the two love letter events reflect the progress of China\u27s modernization process in terms of neutral moral concepts
A Study on the Interaction between Gender Morality and Free Love in Early 20th Century China : Centered on Du Cheng Shu&Qu Jiang\u27s Love Letter
This article attempts to answer the question of "love" and why it has been prohibited from entering the public sphere in Chinese history. This article takes the "Love Letter Incident" as a case study and uses the process tracking method to analyze the love letter incident between Du Chengshu (æææ·) and Qu Jiang (ć±ç). In this event, various social groups interacted on this matter, so this article horizontally compared the thinking and self-expression of young men and women in the face of love issues and vertically explored the premature and delayed disclosure of love issues under the trend of gender equality in China since the early 20th century. Examining and evaluating love issues by various parties in the public sphere is necessary for private love writing to move toward the public sphere. Through various evaluations of love letters, the issue of love has entered the public sphere. However, in China at the beginning of the 20th century, the issue of love still faced scrutiny from traditional Chinese gender morality and morality, making it difficult for love issues to be made public. This article finds that in early 20th-century China. The concept of "gender equality" accompanied by China\u27s modernization movement (May Fourth Movement) was valued by society, and the morality of "gender equality" has never been established. However, Chinese society still maintains an unfriendly attitude towards women, and the perception of gender inequality is still considered normal
An Optimal Linear Time Algorithm for Quasi-Monotonic Segmentation
Monotonicity is a simple yet significant qualitative characteristic. We consider the problem of segmenting an array in up to K segments. We want segments to be as monotonic as possible and to alternate signs. We propose a quality metric for this problem, present an optimal linear time algorithm based on novel formalism, and compare experimentally its performance to a linear time top-down regression algorithm. We show that our algorithm is faster and more accurate. Applications include pattern recognition and qualitative modeling
A Survey Study: The Correlation between Introversion/Extroversion and Oral English Learning Outcome
Introversion/extroversion is generally considered to be one of the most important factors affecting the success of foreign language learning, especially spoken language. Extroverts are usually thought to be better at learning a foreign spoken language than introverts. With the intention of finding out whether extroverts are better learners of spoken English (learned as a foreign language in China) than introverts, this study investigated 117 English majorsâ personality types (in terms of introversion and extroversion) in Chongqing (a municipality city in China), and their spoken English performance through a spoken English test. With the data collected, this paper analyzes the correlation between introversion/extrusion and spoken English performance. The result shows that the two are not correlated. The author discusses factors leading to this phenomenon from various aspects of learning environment, motivation, language intake and output, culture, and concludes that introversion/ extroversion is not a key factor contributing to the success of spoken English learning. The research result is of great significance to both English teachers and learners, especially those who are concerned about their personality (introversion) being a barrier to their oral English learning. What matters most in spoken English learning probably are the strategies that learners employ to improve it, which is well worth researching

Integration of Workflow and Agent Technology for Business Process Management
Both workflow and agent technology have recently been applied to business process management. The integration of these two technologies will definitely provide solutions to the problems not to be solved by any of them individually. This paper summarises the capabilities of these two technologies and discusses the forms and their benefits of integrating them for business process management. Generally, agent enhanced workflow management and agent-based workflow management are the main forms for applications of intelligent agents to workflow systems. Some research issues in each form are discussed. A conclusion with discussions of future research directions is also given
