12導程影像模式心電圖系統改進與病症資料庫建立12-Lead Image Format ECG System Improvement and Clinical Database Development張敏軒Min Xuan Chang醫學工程研究所關鍵詞:心電圖;額平面;橫平面;病症資料庫;峰值;投影軸向;Keyword:electrocardiography;frontal plane;horizontal plane;clinical database;peak;projection axis;摘要:傳統的心電圖（Electrocardiography,ECG）共有十二個導程，包括心電訊號在額平面（frontal plane）六個導程的投影和在橫平面（horizontal plane）六個導程的投影。
由於十二導程心電圖是三度空間的心電訊號投射結果，然而傳統的心電圖所呈現資訊僅限於時間與振幅的二維變化，缺乏時間與空間整體資訊的呈現；以致於判讀診斷上，由於欠缺整體資訊呈現，醫師需在腦中進行組合辨識，過程較為繁瑣，且對某些病症不易以目視判斷。
本研究利用影像模式顯示方法，將12導程心臟電氣訊號整合成兩張影像；橫平面影像顯示從導程V1到V6（涵蓋橫平面120¡空間角範圍）的心臟電氣訊號所組成的影像；額平面影像顯示從導程III到aVL（涵蓋額平面150¡空間角範圍）的心臟電氣訊號所組成的影像。
傳統12導程心電圖需觀察12條線段的診斷過程，化簡為觀察兩張心電圖影像。
這兩張整合性的影像可提供心臟電氣訊號於空間和時間分佈變化整體的資訊；再配合電腦運算及顯示技術，可以增加以視覺直接觀察的辨識能力。
本研究中，建置臨床病症資料庫，資料庫總共收錄309人，年齡分佈41～90歲，經歸類與彙整區分為14種心臟相關疾病，從資料庫中制定影像模式心電圖判讀準則，突顯病症與影像模式心電圖的相關性。
為了呈現心電訊號在空間分佈的全貌與特定病症診斷需求，擴大兩平面的空間角範圍為360¡。
文化严谨性的英文名词解释Cultural Rigor: Understanding the ConceptIntroductionCulture plays a significant role in shaping societies, and one of its fundamental aspects is its rigor. Cultural rigor refers to the strict adherence to established norms, values, and customs within a society. It encompasses various elements such as traditions, protocols, etiquettes, and intellectual rigor. In this article, we will delve deeper into understanding the concept of cultural rigor and its implications for individuals and communities.Defining Cultural RigorCultural rigor can be understood as the meticulous observance of cultural practices, intellectual pursuits, and the pursuit of excellence within a particular culture. It involves emphasizing discipline, precision, and adherence to established rules and standards. Cultural rigor encompasses both the tangible aspects of a culture, such as rituals and ceremonies, as well as the intangible elements like the pursuit of knowledge, artistic expression, and the honoring of traditions.Historical Significance of Cultural RigorCultural rigor has existed throughout history, playing a vital role in the preservation and evolution of societies. Ancient civilizations, such as the Chinese, Egyptians, and Greeks, emphasized the importance of cultural rigor to maintain social order, transmit knowledge, and lead to societal advancements. Examples include Confucianism's emphasis on hierarchy, ancient Egypt's meticulously recorded rituals, and ancient Greece's focus on intellectual excellence through disciplines like philosophy and mathematics.Cultural Rigor in Contemporary SocietyIn contemporary society, cultural rigor continues to play a crucial role in maintaining the fabric of communities and shaping individual identities. It allows individuals to connect with their roots, identity, and heritage, fostering a sense of belonging and pride. Cultural rigor extends to various spheres, including education, arts, language, and social interactions.Educational Aspects of Cultural RigorEducation is a significant domain where cultural rigor finds expression. Within educational institutions, cultural rigor is evident in the preservation and promotion of cultural values, language, and history.

以我眼中的时尚为题作文英语Fashion has been an integral part of human society for centuries, evolving and transforming with the changing times. As an observer and a participant in the ever-changing world of fashion, I have developed a unique perspective on this dynamic and multifaceted industry. In my eyes, fashion is not merely about the clothes we wear, but a reflection of our personal identity, cultural heritage, and societal trends.At its core, fashion is a form of self-expression. It allows individuals to communicate their unique personalities, values, and aspirations through the way they present themselves to the world. The clothes we choose to wear can convey our mood, our interests, and our sense of style. A bold and vibrant outfit might suggest a confident and outgoing individual, while a more subdued and minimalist look could reflect a preference for understated elegance.Fashion also serves as a window into the cultural and historical context of a society. The styles and trends that emerge often reflect the values, beliefs, and social norms of a particular time and place.For instance, the flamboyant and extravagant fashions of the 18th-century French aristocracy were a manifestation of the opulence and grandeur of the Versailles court. Similarly, the punk rock movement of the 1970s gave rise to a distinct fashion aesthetic that challenged the mainstream and expressed the rebellious spirit of the era.In today's globalized world, fashion has become an increasingly interconnected and diverse field. Designers, brands, and consumers from all corners of the globe are constantly influencing and inspiring one another, creating a rich tapestry of styles and trends. The rise of social media and digital platforms has further amplified the reach and impact of fashion, allowing individuals to share their personal style and discover new and innovative looks.One of the most fascinating aspects of fashion, in my opinion, is its ability to both reflect and shape societal attitudes and values. As social and cultural norms evolve, so too do the ways in which we dress and present ourselves. The increasing emphasis on sustainability and ethical consumption, for example, has led to a growing awareness of the environmental and human impact of the fashion industry. Consumers are now more conscious of the materials, production methods, and labor practices behind the clothes they buy, driving a shift towards more responsible and mindful fashion choices.Moreover, fashion has played a significant role in challenging and redefining traditional gender norms and stereotypes. The androgynous and gender-fluid styles that have gained popularity in recent years are a testament to the growing acceptance and celebration of diverse gender expressions. Fashion has become a powerful medium for individuals to challenge societal expectations and assert their own unique identities.At the same time, the fashion industry is not without its flaws and controversies. Issues such as body image, diversity, and inclusivity have long been at the forefront of discussions within the industry. The persistent prevalence of unrealistic beauty standards and a lack of representation for marginalized communities have contributed to a growing call for more inclusive and equitable practices in the fashion world.Despite these challenges, I believe that fashion remains a powerful and dynamic force that has the potential to inspire, empower, and transform. By embracing the diversity and creativity inherent in fashion, we can challenge the status quo, celebrate our individuality, and create a more inclusive and sustainable future for the industry.In conclusion, my perspective on fashion is one that recognizes its multifaceted and complex nature. Fashion is not just about the clothes we wear, but a reflection of our personal, cultural, andsocietal identities. It is a constantly evolving and interconnected field that both shapes and is shaped by the world around us. As we navigate the ever-changing landscape of fashion, it is important to remain mindful of its impact and to strive for a more inclusive, sustainable, and empowering future for all.。

They take turns playing, with Bela going first. At his first turn, Bela chooses any real number in theinterval . Thereafter, the player whose turn it is chooses a real numberthat is more than one unit away from all numbers previously chosen by either player. A player unable to choose such a number loses. Using optimal strategy, which player will win the game?SolutionNotice that to use the optimal strategy to win the game, Bela must select themiddle number in the range and then mirror whatever number Jennselects. Therefore, if Jenn can select a number within the range, so can Bela. Jenn will always be the first person to run out of a number to choose, so theanswer is .Solution 2 (Guessing)First of all, realize that the value of should have no effect on the strategy at all. This is because they can choose real numbers, not integers, so even if is odd, for example, they can still go halfway. Similarly, there is no reason the strategy would change when .So we are left with (A) and (B). From here it is best to try out random numbers and try to find the strategy that will let Bela win, but if you can't find it, realize thatit is more likely the answer is since Bela has the first move and thus has more control.Problem17There are people standing equally spaced around a circle.

英语作文中国文化使我的生活充实作文初二全文共3篇示例，供读者参考篇1Chinese Culture Enriches My LifeAs a middle school student in China, I am fortunate to be immersed in a rich cultural heritage that spans thousands of years. From ancient philosophies to traditional arts and festivals, Chinese culture has profoundly shaped my perspectives and enriched my daily life in countless ways.One aspect of Chinese culture that has significantly influenced me is the emphasis on education and lifelong learning. Confucius, the renowned philosopher, once said, "Learning never exhausts the mind." This principle has been ingrained in Chinese society for centuries, and it resonates deeply with me. I have been taught from a young age to value knowledge, to work hard in my studies, and to continuously strive for self-improvement.My parents and teachers have instilled in me a deep respect for education and the pursuit of wisdom. They often remind me that knowledge is not only a means to academic success but alsoa path to personal growth and a better understanding of the world around us. This mindset has motivated me to approach my studies with enthusiasm and dedication, always striving to expand my horizons and learn something new every day.Another aspect of Chinese culture that has enriched my life is the emphasis on harmony, balance, and interconnectedness. The concept of yin and yang, which represents the complementary forces of opposites, is deeply rooted in Chinese philosophy. This principle has taught me to seek balance in all aspects of my life, to appreciate the interconnectedness of all things, and to strive for harmony within myself and with the world around me.I have learned to approach challenges with a calm and balanced mindset, recognizing that difficulties and setbacks are natural parts of life's journey. Instead of becoming overwhelmed or discouraged, I strive to maintain a sense of inner peace and perspective, trusting that with patience and perseverance, solutions will emerge.Chinese culture has also shaped my appreciation for the arts and creativity. From calligraphy and poetry to traditional music and dance, Chinese art forms have a rich history and profound symbolism. I have had the opportunity to learn and practicesome of these art forms, which has not only allowed me to develop new skills but has also deepened my understanding and appreciation of my cultural heritage.When I practice calligraphy, for instance, I find a sense of tranquility and focus as I carefully guide the brush across the paper, creating beautiful characters that embody the harmony of form and meaning. The rhythmic movements and the sound of the brush on paper transport me to a serene state of mind, allowing me to temporarily escape the stresses of daily life and connect with something deeper within myself.Chinese festivals and celebrations have also played a significant role in enriching my life and strengthening my connection to my cultural roots. The vibrant and colorful festivities, such as the Chinese New Year, Mid-Autumn Festival, and Dragon Boat Festival, are not only occasions for joy and merriment but also opportunities to honor traditions, strengthen family bonds, and appreciate the rich tapestry of customs and rituals that have been passed down through generations.During these festivals, I have learned about the stories and legends behind the celebrations, participated in time-honored traditions, and savored the delicious traditional foods that are an integral part of the festivities. These experiences have instilled inme a deep sense of pride and belonging, reminding me of the rich cultural heritage that I am a篇2The Enriching Influence of Chinese Culture on My LifeBeing raised in China has allowed me to be immersed in a deep and ancient culture that has shaped so much of who I am today. From the earliest days of my childhood, I have been surrounded by traditions, values, and ways of life that make the Chinese cultural heritage so vibrant and meaningful. As I have grown older, I have come to appreciate this profound legacy more and more. It enriches my life in countless ways.One of the most visible and tangible aspects is the wealth of celebrations and festivals that punctuate the Chinese calendar year. The most prominent, of course, is Chinese New Year - an epic festivity filled with family gatherings, feasting, fireworks, red envelopes, and an unparalleled sense of joy and happiness. I always look forward to this highlight of the year with immense excitement and anticipation.But there are so many other culturally significant events too. The Mid-Autumn Festival, with its delicious mooncakes and colorful lanterns. The Qingming Festival, where we pay respectsto our ancestors. The Dragon Boat Festival with its sticky rice dumplings and dragon boat races. Each one allows me to participate in age-old customs that connect me to my heritage in a powerful way.Beyond the celebratory events, Chinese culture embedded in my daily life through the food I eat. I have been raised on a wonderful array of authentic Chinese cuisines from different regions - the fiery Sichuan dishes, the subtle Cantonese flavors, the creative fusions of Shanghai's happenin' culinary scene. Exploring this incredibly diverse and delicious culinary world is a passion of mine. Cooking and sharing meals is also a cornerstone of Chinese family life that I cherish.My upbringing has instilled in me the traditional values that have defined Chinese society for thousands of years. Values like filial piety, showing respect and care for one's family. The importance of working hard, pursuing knowledge, and bringing honor through personal achievement. Having humility and living in harmony. While modern life in China is rapidly evolving, these core ethical precepts remain vital guideposts.The stories, legends, and history I have learned about have allowed me to walk in the footsteps of the countless generations that came before me. I have developed a deep appreciation forthe narrative of my civilizational identity. The heroic tales of virtuous warriors, mighty emperors, and sagely philosophers. The fables that teach moral lessons through symbolic animals and parables. The epics of romance, tragedy, and triumph that have been passed down over the ages. Engaging with this rich literary and storytelling tradition roots me to my culture.I have also grown up being exposed to traditional Chinese arts, crafts, and entertainment from a young age. Watching Peking Opera performances with their ornate costumes and stylized movements. Practicing calligraphy and marveling at the intricate paintings and ceramics. Listening to the unique regional musical styles and instrumentations. These proud cultural expressions connect me to the artistic soul of my people.The beautiful natural landscapes of my homeland, from the misty mountains to the shimmering rivers, have also shaped my perspectives and identity. I have been taught to appreciate and commune with nature through the Chinese philosophical traditions of Daoism and the ancient concept of "qing jing" - reveling in life's simple joys. Being at one with the natural world is a source of serenity I deeply cherish.Even my name itself, written in pivotal Chinese characters, is a symbolic representation of my heritage that I will carry forever.The deeper I journey into understanding my rich cultural rootsbred, the more I am able to make sense of who I am and my place in this world.As I look ahead to my future, I know that the profound teachings, customs, and identity inherent in Chinese culture will remain integral parts of how I live my life and what I value most. The wisdom, creativity, and sense of continual rediscovery that comes from this inheritance will ensure that my days remain enriched and fascinating.While I am also a global citizen, simultaneously being exposed to other cultures and perspectives, my Chinese core will always be the secure foundation from which I grow. It fills me with immense pride to be the living embodiment of this ancient 5,000-year civilization that has had such an indelible impact on humanity. I will celebrate and honor it for the rest of my days through how I walk my own life's journey.篇3Chinese Culture Enriches My LifeBeing raised in a Chinese family, I have been immersed in the rich cultural traditions of China from a very young age. As I've grown older, I've come to truly appreciate how these customsand values have shaped who I am and enriched my life in countless ways.One of the most fundamental aspects of Chinese culture that I embrace is the emphasis on education and hard work. In our culture, education is viewed as the pathway to success andself-improvement. My parents have always stressed the importance of studying diligently and performing well academically. While at times the pressure to excel can be intense, I've learned that perseverance and a strong work ethic are essential for achieving one's goals. The satisfaction I feel when my efforts pay off is unmatched.This focus on education is deeply rooted in the philosophical teachings of Confucius. Principles like filial piety, which emphasizes respecting and honoring one's parents and elders, have instilled in me a great appreciation for my family. The strong family values inherent in Chinese culture have created an incredibly close bond between my relatives. We frequently gather for special occasions and holidays, sharing laughter, stories, and delicious homecooked meals. These moments bring me an immense sense of joy, love, and belonging that I'm grateful for.Beyond academics and family, Chinese culture has opened my eyes to a world of fascinating customs and traditions. I love the vibrant celebrations of holidays like Chinese New Year. Decorating the house with auspicious red decorations, eating symbolic dishes like dumplings, and receiving red envelopes from older relatives fill me with excitement each year. The dazzling displays of fireworks and dragon dances connect me to the ancient roots of these millennia-old practices. Participating in these rituals makes me feel profoundly connected to my heritage.My fluency in Chinese has also allowed me to deeply engage with the nation's rich literary history. I'm captivated by the prowess of poets like Li Bai and the philosophical depth of ancient texts like the Analects of Confucius. Reading these works instills in me a sense of wisdom and provides guidance on leading an ethical, principled life. Embodying values like humility, respect for others, and harmony with nature enriches my soul.The traditional arts like calligraphy, paper cutting, and Chinese painting require incredible patience, discipline, and attention to detail - qualities that Chinese culture heavily emphasizes. Attempting these intricate crafts has taught me fortitude and the rewards of persisting through challenges. Evenif my skills are lacking, the process of practicing these artforms clears my mind and allows me to find peace amid the academic pressures of school life.Of course, Chinese culture encompasses more than just the ancient traditions. The rapid development and globalization happening in China today is astounding. I'm constantly in awe of the technological marvels and ambitious infrastructure projects underway, from maglev trains to towering megacities. This forwards-looking spirit coexisting with steadfast cultural roots is something I take great pride in. It motivates me to be open to change and innovation while remaining grounded in my values.On a personal level, the profound impact Chinese culture has had on my life manifests in my day-to-day actions and behavior. Something as simple as greeting friends and family by saying "Have you eaten?" rather than "How are you?" reflects how our culture emphasizes community, hospitality, and ensuring the physical needs of others are met. I've internalized the importance of humility, listening to others' perspectives, and striving to live with integrity - values rooted in китайский учения.As I look ahead to adulthood, I know the moral education and life lessons embedded in Chinese culture will continue to guide me along the right path. The concepts of hard work,respect, and righteousness will serve as my compass, helping me to make choices with wisdom and honor. Celebrating my heritage through embracing its colorful customs will forever be a source of identity and pride.While I was born in this modern age, an ancient proverb still rings true for me: "I am just a tiny leaf from the same celebrated tree of Chinese culture." My life has been profoundly shaped and enriched by these traditions stretching back thousands of years. The legacy and brilliance of Chinese culture flows through my veins, grounding my sense of self while giving me roots that will nurture me for a lifetime.。

R.Acad.Sci.Paris201,536–537(1935);Physics7,195–202(1936)].The original solution was obtained by superposition upon Kelvin’s solution,corresponding to a force at a point of a medium occupying the entire space,of solutions of thefield equations which possess singularities outside a half-space containing the point of application of the force,and which annul the tractions on the plane boundary of the half-space.In the present paper the solution is reached by more direct and systematic means.The author first extends his completeness proof[Bull.Amer.Math.Soc.42,373–376(1936)]for the solution of thefield equations appropriate to a linear,isotropic,elastic medium,in terms of the Boussinesq-Papkovich stress functions,to the case in which body forces are present.He then considers the problem of the half-space subjected to body forces which vanish outside a bounded region T surrounding the load-point P.By means of the Boussinesq-Papkovich stress functions this problem is reduced to the problem in potential theory which consists in determining a function from its given boundary values and the known value of its Laplacian throughout the region under consideration.Thus an integral representation of the solution,involving Green’s function of the first kind,is established.The solution to the concentrated-load problem is obtained in closed form through an elementary limit process in which T is shrunk to P while the resultant body force is made to tend to the prescribed concentrated load.Reviewed by E.Sternberg c Copyright American Mathematical Society1954,2012。
