Intelligent Systems Analyzing Sections of the Great Wall of China for Ming and Pre-Ming Dynasty Construction THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Jin Rong Yang Graduate Program in Civil Engineering The Ohio State University 2012 Master's Examination Committee: Dr. Fabian Tan, Advisor Dr. Frank Croft Dr. Shive Chaturvedi Copyright by Jin Rong Yang 2012 Abstract As society moves into the future, environmental concerns such as global warming increase due to human activity (U.S. EPA 2009:2). In construction, the use of cement in concrete contributes to this problem. Scientists and Engineers believe building green, yet durable, is the key to solving this problem. To achieve this goal, researchers must move backward in time to examine how our predecessors built their structures without modern technology, and then they can incorporate the techniques that were used to reduce waste. One of the most qualified structures to examine is the Great Wall of China. The technology they used was not only environmentally friendly, but the structure is also very durable. Some parts of the structure that were built over two thousand years ago still exist today. The research is focused on Ming and Pre Ming dynasty. The research centers on the similarities and differences between the two time periods in construction techniques. Since the Great Wall is very long in length, this research and the research methods mentioned below are limited to Beijing, Hebei and Gansu province. iii The author found out that the main construction method that was used was rammed earth. The rammed earth method is a technique of building walls by compressing the raw materials such as earth, gravel and lime into the shape of a wall. The construction materials that they used to construct the Great Wall were mainly fire kiln bricks and mud bricks. Fire kiln bricks are made through chemical change when the clay is fired up in the kilns until it is vitrified. Mud bricks, on the other hand, are made through a physical change by letting the bricks dry out in the sun. The main transportation of the material to construct the Great Wall was using a class 2 lever wheelbarrow, though the workers used animals as well. Since the Great Wall was built a long time ago, many historical records and documents were lost or destroyed. The methods listed above are not binary, meaning they are not completely true or false. The author would have to incorporate fuzzy logic to measure the statements, such as how “true” they are, using subjective values. The author also uses Artificial Intelligence and Multi-Media system in his research to assist the end user in the absence of a Great Wall expert. The research results are shown in the Multi-Media system. The research shows that the Great Wall from the Ming dynasty is far superior to the dynasties before it in terms of construction techniques. However; Pre-Ming Dynasty does incorporate more green construction iv techniques than the Ming Dynasty. Therefore, the author concludes that the structure is durable when it is from the Ming dynasty. The structure is greener when it is from the Pre-Ming dynasty. However, both Ming and Pre-Ming Dynasty’s construction methods are greener than modern practices. With these conclusions, the author recommends using both construction methods from the Ming and the Pre-Ming dynasties to build green yet durable structures for the future. v Dedication This document is dedicated to my Mother Whon Jing, my Father Gwon Fang and my friends. vi Acknowledgments I would like to thank Dr. Fabian Tan for mentoring and supporting me throughout my undergraduate and graduate studies. I would also like to thank him for helping and guiding me in the right direction for my thesis. Furthermore, I would like to thank the committee members Dr. Frank Croft and Dr. Shive Chaturvedi for their suggestions on my thesis as well. Lastly, I would like to thank Katharine Hibbard, Jamie Crowsley and Bart Ridgill for proofreading my thesis. Next, I would like to thank my friends who gave me positive encouragement and support throughout my college career. I would like to thank Bart, Jinhang and others who took CE 881 and CE 888 with me. They were there for mental support when we took those classes together and they still give me positive advice and support now that the classes have ended. I would like to thank my closest friends Jimme, Matt and vii others (you know who you are) for their continuing support outside the academia. Finally, I would like give the deepest thank you to my Mom, Whon Jing, and my Dad, Gwon Fang, for their love and support throughout my life. They kept me going by encouraging me to go farther with school and in life even though I feel like quitting during the hard times. Without them, I would not be here. Mom, this is for you and you will forever be in my heart. viii Vita June 2006 ................................................Eastmoor Academy High School March 2011 .............................................B.S. in Civil Engineering, Ohio State University 2012 to present ......................................Graduate Teaching Associate, Engineering Education Innovation Center, The Ohio State University Fields of Study Major Field: Civil Engineering Specialization: Construction ix Table of Contents Abstract ................................................................................................................... iii Dedication ............................................................................................................. vi Acknowledgments ...............................................................................................vii Vita ...........................................................................................................................ix Fields of Study .........................................................................................................ix Table of Contents .................................................................................................. x List of Tables .......................................................................................................... xv List of Figures ........................................................................................................ xvi CHAPTER 1: INTRODUCTION .................................................................................. 2 1.1 Introduction ................................................................................................... 2 1.2 Goal, Objectives and Tasks ........................................................................ 3 1.3 Scope of Study.............................................................................................. 6 1.4 Limitations ...................................................................................................... 7 CHAPTER 2 LITERATURE SEARCH ........................................................................... 8 x 2.1 Brief History of Who, When and Where ..................................................... 8 2.2 Why build the Great Wall and why did it never fulfill its purpose? ..... 12 CHAPTER 3 HOW DID THE ANCIENT CHINESE CONSTRUCT IT? ....................... 15 3.1 Legendary ‘How’........................................................................................ 15 3.2 Historical ‘How’ ........................................................................................... 16 3.2.1 Before the Ming Dynasty .................................................................... 16 3.2.2 Ming Dynasty ........................................................................................ 19 3.3 Factual ‘How’ ............................................................................................. 23 3.3.1 Before the Ming Dynasty .................................................................... 23 3.3.2 Ming Dynasty ........................................................................................ 29 3.4 Conclusion ................................................................................................... 37 CHAPTER 4: OVERVIEW OF THE COMPUTER PROGRAMS ............................... 40 4.1 Introduction ................................................................................................. 40 4.2 Program Usage and Limitation ................................................................ 40 4.3 End User’s Knowledge ............................................................................... 41 4.4 Conclusion ................................................................................................... 42 CHAPTER: 5 DECISION TREE ................................................................................. 43 5.1 Introduction to the Decision Tree............................................................. 43 xi 5.2 The Decision Tree for this Research ......................................................... 44 5.3 Conclusion to the Decision Tree .............................................................. 47 CHAPTER 6: ARTIFICIAL INTELLIGENCE ............................................................... 48 6.1 Introduction to the Artificial Intelligence ................................................ 48 6.2 Knowledge–Based Expert System (KBES) ................................................ 49 6.2.1 Architecture of the KBES ..................................................................... 50 6.2.2 The Knowledge Base ..........................................................................

    GREAT WALL of CHINA Deconstructing

    GREAT WALL OF CHINA Deconstructing History: Great Wall of China It took millennia to build, but today the Great Wall of China stands out as one of the world's most famous landmarks. Perhaps the most recognizable symbol of China and its long and vivid history, the Great Wall of China actually consists of numerous walls and fortifications, many running parallel to each other. Originally conceived by Emperor Qin Shi Huang (c. 259-210 B.C.) in the third century B.C. as a means of preventing incursions from barbarian nomads into the Chinese Empire, the wall is one of the most extensive construction projects ever completed… Though the Great Wall never effectively prevented invaders from entering China, it came to function more as a psychological barrier between Chinese civilization and the world, and remains a powerful symbol of the country’s enduring strength. QIN DYNASTY CONSTRUCTION Though the beginning of the Great Wall of China can be traced to the third century B.C., many of the fortifications included in the wall date from hundreds of years earlier, when China was divided into a number of individual kingdoms during the so-called Warring States Period. Around 220 B.C., Qin Shi Huang, the first emperor of a unified China, ordered that earlier fortifications between states be removed and a number of existing walls along the northern border be joined into a single system that would extend for more than 10,000 li (a li is about one-third of a mile) and protect China against attacks from the north.

    (And Misreading) the Draft Constitution in China, 1954

    Textual Anxiety Reading (and Misreading) the Draft Constitution in China, 1954 ✣ Neil J. Diamant and Feng Xiaocai In 1927, Mao Zedong famously wrote that a revolution is “not the same as inviting people to dinner” and is instead “an act of violence whereby one class overthrows the authority of another.” From the establishment of the People’s Republic of China (PRC) in 1949 until Mao’s death in 1976, his revolutionary vision became woven into the fabric of everyday life, but few years were as violent as the early 1950s.1 Rushing to consolidate power after finally defeating the Nationalist Party (Kuomintang, or KMT) in a decades- long power struggle, the Chinese Communist Party (CCP) threatened the lives and livelihood of millions. During the Land Reform Campaign (1948– 1953), landowners, “local tyrants,” and wealthier villagers were targeted for repression. In the Campaign to Suppress Counterrevolutionaries in 1951, the CCP attacked former KMT activists, secret society and gang members, and various “enemy agents.”2 That same year, university faculty and secondary school teachers were forced into “thought reform” meetings, and businessmen were harshly investigated during the “Five Antis” Campaign in 1952.3 1. See Mao’s “Report of an Investigation into the Peasant Movement in Hunan,” in Stuart Schram, ed., The Political Thought of Mao Tse-tung (New York: Praeger, 1969), pp. 252–253. Although the Cultural Revolution (1966–1976) was extremely violent, the death toll, estimated at roughly 1.5 million, paled in comparison to that of the early 1950s. The nearest competitor is 1958–1959, during the Great Leap Forward.

Green development is the hot spot of cold chain logistics today. +erefore, this paper converts carbon emission into carbon emission cost, comprehensively considers cargo damage, refrigeration, carbon emission, time window, and other factors, and establishes the optimization model of location of low-carbon cold chain logistics in the Beijing-Tianjin-Hebei metropolitan area. Aiming at the problems of the fish swarm algorithm, this paper makes full use of the fireworks algorithm and proposes an improved fish swarm algorithm on the basis of the fireworks algorithm. By introducing the explosion, Gaussian mutation, mapping and selection operations of the fireworks algorithm, the local search ability and diversity of artificial fish are enhanced. Finally, the modified algorithm is applied to optimize the model, and the results show that the location scheme of low-carbon cold chain logistics in Beijing-Tianjin-Hebei metropolitan area with the lowest total cost can be obtained by using fireworks-artificial fish swarm algorithm.
