Applications And Types Of Smart Materials Engineering Essay

Applications And Types Of Smart Materials Engineering Essay Smart material are those that change in response to changing conditions in their surrounding or in the application of other directed influences such as passing an electric charge through them. Modern products increasingly use them, shirts that change color with changes in temperature. Smart materials are the materials that have one or more properties that can be significantly changed in a controlled style such as stress, temperature, moisture, pH, electric or magnetic fields. There are many types of smart material some of which are already common. Some examples are as following: Types of smart material Some types of smart materials include: Piezoelectric On applying a mechanical stress to these materials it generates an electric current. Piezoelectric microphones transform changes in pressure caused by sound waves into an electrical signal. Shape memory After deformation of these materials they remember their original shape and return back to its original shape when heated .Applications include shape memory stents tubes threaded into arteries that expand on heating to body temperature to allow increased blood flow. Thermo chromic These are the materials which change their color in response to changes in temperature. They have been used in bathplugs that change color when the water is too hot. Photo chromic These materials change color in response to changes in light conditions. Uses include security ink sand dolls that tan in the sun. Magneto rheological: it is a fluid that fluids become solid when placed in a magnetic field. They can be used to construct dampers that suppress vibrations. These can be used for buildings and bridges to suppress the damaging effects of, For example, high winds or earthquakes. 1.1 pH-sensitive polymers These are materials which swell/collapse when the pH of the surrounding media changes. PH sensitive or pH responsive polymers are materials which will respond to the changes in the pH of the surrounding medium by varying their dimensions. Such materials swell or collapse depending on the pH of their environment. This behavior is exhibited due to the presence of certain functional groups in the polymer chain. 1.2 Magnetostrictive materials exhibit change in shape under the influence of magnetic field and also exhibit change in their magnetization under the influence of mechanical stress Fig 1.1 Magnetostrictive material (inside) then magnetizing coil over it and magnetic enclosure completing the magnetic circuit (outside) It can convert magnetic energy into kinetic energy that is used to build sensors. 1.3 Temperature-responsive polymers These are materials which changes upon temperature. A temperature-responsive polymer is a polymer which undergoes a physical change when external thermal is applied. The ability to undergo such changes makes this class of polymers the category of smart materials. 1.4 Self-healing materials These materials have the intrinsic ability to repair damage due to normal usage, thus expanding the materials lifetime .These are the class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. The inspiration comes from biological systems, which have the ability to heal after being wounded. Initiation of cracks and other types of damage on a microscopic level has been shown to change thermal, electrical, and acoustical properties, and eventually lead to whole scale failure of the material. Usually, cracks are mended by hand, which is difficult because cracks are often hard to detect. A material (polymers, ceramics, etc) that can intrinsically correct damage caused by normal usage could lower production costs of a number of different industrial processes through longer part lifetime, reduction of inefficiency over time caused by degradation, as well as prevent costs incurred by material failure Chapter 2 Applications of Smart Materials There are many possibilities for such materials and structures in the manmade world. Engineering structures could operate at the very limit of their performance envelopes and to their structural limits without fear of exceeding either. These structures could also give maintenance engineers a full report on performance history, as well as the location of defects, whilst having the ability to counteract unwanted or potentially dangerous conditions such as excessive vibration, and affect self repair. The Office of Science and Technology Foresight Programme has stated that `Smart materials will have an increasing range of applications (and) the underlying sciences in this area must be maintained at a standard which helps achieve technological objectives, which means that smart materials and structures must solve engineering problems with hitherto unachievable efficiency, and provide an opportunity for new wealth creating products. 2.1 Smart Materials in Aerospace Some materials and structures can be termed sensual devices. These are structures that can sense their environment and generate data for use in health and usage monitoring systems (HUMS). To date the most well established application of HUMS are in the field of aerospace, in areas such as aircraft checking. An airline such as British Airways requires over 1000 employees to service their 747s with extensive routine, ramp, intermediate and major checks to monitor the health and usage of the fleet. Routine checks involve literally dozens of tasks carried out under approximately 12 pages of densely typed check headings. Ramp checks increase in thoroughness every 10 days to 1 month, hanger checks occur every 3 months, interchecks every 15 months, and major checks every 24000 flying hours. In addition to the manpower resources, hanger checks require the aircraft to be out of service for 24 hours, interchecks require 10 days and major checks 5 weeks. The overheads of such safety monitoring are enormous. An aircraft constructed from a sensual structure could self-monitor its performance to a level beyond that of current data recording, and provide ground crews with enhanced health and usage monitoring. This would minimize the overheads associated with HUMS and allow such aircraft to fly for more hours before human intervention is required. 2.2 Smart Materials in Civil Engineering Applications However, sensual structures need not be restricted to hi-tech applications such as aircraft. They could be used in the monitoring of civil engineering structures to assess durability. Monitoring of the current and long term behavior of a bridge would lead to enhanced safety during its life since it would provide early warning of structural problems at a stage where minor repairs would enhance durability, and when used in conjunction with structural rehabilitation could be used to safety monitor the structure beyond its original design life. This would influence the life costs of such structures by reducing upfront construction costs (since smart structures would allow reduced safety factors in initial design), and by extending the safe life of the structure. Sensual materials and structures also have a wide range of potential domestic applications, as in food 2.3 Its properties which enable them for civil engineering application are    Repeated absorption of large amounts of strain energy under loading without permanent deformation. Possibility to obtain a wide range of cyclic behavior -from supplemental and fully reentering to highly dissipating-by simply varying the number and/or the characteristics of SMA components. Usable strain range of 70% Extraordinary fatigue resistance under large strain cycles Their great durability and reliability in the long run. 2.4 STRUCTURAL APPLICATION OF SMART MATERIALS The development of durable and cost effective high performance construction materials and systems is important for the economic well being of a country mainly because the cost of civil infrastructure constitutes a major portion of the national wealth. To address the problems of deteriorating civil infrastructure, research is very essential on smart materials. This paper highlights the use of smart materials for the optimal performance and safe design of buildings and other infrastructures particularly those under the threat of earthquake and other natural hazards. The peculiar properties of the shape memory alloys for smart structures render a promising area of research in this field. Fig 2.1 to achieve speed improvements on existing bridges and to maintain the track in a straight and non-deformed configuration as the train passes With the help of optimal control methodology the train will pass the bridge with reduced track deflections and vibrations and thus velocity could be safely increased. Fig2.1 shows various positions of the train with and without active railway track support. Chapter3 3.1 Reducing waste Producers are forced to consider the entire life of a product at the design stage and customers are increasingly demanding more environmentally sensitive products. Innovative use of smart materials has the potential to reduce waste and to simplify recycling. Electronic waste Electronic waste is the fastest growing component of domestic waste in the UK. Electrical equipment requires that it should be processed before disposal to remove hazardous and recyclable materials. Disassembly of product is expensive and time consuming but the use of smart materials could help to automate the process. Research in this active disassembly has been carried out by UK companies. Active Disassembly Research Ltd. One example uses fasteners constructed from shape memory materials that can self release on heating. Once the fasteners have been released, components can be separated simply by shaking the product. By using fasteners that react to different temperatures, products could be disassembled. 3.2 Research in the UK Smart materials and systems are interdisciplinary subject areas so funding does not come from a single research council. However, the majority of research council funding is allocated by the Engineering and Physical Sciences Research Council (EPSRC). Materials research is one of its six core programmers and it currently has a commitment of  £21m to smart materials research in 28 UK universities. This includes the EPSRCs contribution to smart materials projects run in collaboration with 35different organizations including the Ministry of Defense British Aerospace In addition to research councils, the government also allocates funding through the Technology Strategy Board. This is an executive non-departmental public body established by the Government to stimulate innovation in those areas which offer the greatest scope for boosting UK growth and productivity. Advanced materials are one of the Technology Strategy Boards key technology areas, which provide the framework for deciding w here it should invest funding and support activities. In 2007, as part of its support for collaborative research and development, the Technology Strategy Board allocated funding of  £7m to a competition for research proposals in Smart Bioactive and Nano structured Materials for Health The Ministry of Defense identifies smart materials and active structures as a priority technology. However, its investment in these areas has decreased markedly in recent years as developments are increasingly driven by global civil markets and commodity products that are often adequate for itsneeds.2 It currently emphasizes monitoring external research rather than producing it in-house. 3.3 Research worldwide The US is the world leader in smart materials research mainly because of the large defence research and development budget. The US Defense Advanced Research Projects Agency has had an in-house programme of smart materials and structures research since the early 1990s, in contrast to the UK. However the UK is strong in many areas and is at the forefront of research into structures that can repair themselves. Other observations so that materials can be sorted automatically. The companies have collaborated with Nokia and believe that this technology could be in use in the next two years. 3.4 Reducing food waste Food makes up approximately one fifth of the UKs waste. One third of food grown for consumption in the UK is thrown away, much of which is food that has reached its best before date without being eaten .These dates are conservative estimates and actual product life may be longer. Manufacturers are now looking for ways to extend product life with packaging, often using smart materials. CHAPTER 4 FUTURE 4.1 In Nanotechnology to Revolutionize Smart Materials Technology The nanotechnology is set to accelerate development of improved and complicated smart material technologies. Researchers are now considering the possibilities of designing, altering, and controlling material structure at nanoscale levels in order to enhance material performance and process efficiency. The advancements in nanomaterials are expected to increase product quality and performance, and they are finding acceptance in diverse applications such as sensors and electronic devices. Nanosensor particles assist in creating tools for analyzing living cells and serve as reporters in industrial process monitoring. In the future, smart materials are likely to derive their success from nanotechnology that is likely to be instrumental in creating more varied, complex, and intelligent systems. 4.2 Smart Materials Expected to Cater to Diverse Applications The advances and improvements in smart materials allow them to cater to a diverse set of applications, especially in the defense, aerospace, healthcare, electronics, and semiconductor industries. Although very few of these applications are at present commercially viable, their potential for future acceptance is irrefutable. Smart materials are particularly useful for cellular production, observes the analyst. With the addition of cellular fluid and by regulating the cells shape and mechanical conditions, smart materials especially polymers can mimic these cells interactions and exhibit effective results. The computer industry is also adopting smart materials for read/write head micropositioners and next-generation data storage devices. Researchers are developing piezo-accelerometers that anticipate and correct head-motion-related read/write errors. In the healthcare markets, smart material technologies are making their way into several analytical devices for detecting and diagnosing complex medical conditions. With future advances, smart materials are also likely to be useful for fabricating insulin pumps and drug delivery devices.

A Cultural Comparison of English and Chinese Family Names

Abstract The family names of humans are formed and used in the long process of the course of history and the development of society. Family names, being a part of culture, are closely related to history and culture. English and Chinese names are different in their origins and name orders, which is certain to be reflected in their perspective culture.Therefore an exploration of their reflections in the cultural aspects of historical development, feudal history, historical tradition, historical influence and current social situation will be beneficial for the deepening of English study and the mutual understanding and communication of the East and the West. Keywords: Cultural comparison, English family names, Chinese family names, Origin, Name order The word â€Å"culture† comes from the Latin root â€Å"colere† (to inhabit, to cultivate, or to honor).In general, it refers to human activity; different definitions of culture reflect different theories for understanding, or criteria for valuing, human activity. Culture is traditionally the oldest human character, its significant traces separating Homo from australopithecines, and Man from the Animals, though new discoveries are blurring these edges in our day. Sir Edward B. Tylor wrote in 1871 that â€Å"culture or civilization, taken in its wide ethnographic sense, is that complex whole which includes knowledge, belief, art, morals, law, custom, and any other capabilities and habits acquired by man as a member of ociety† while a 2002 document from the United Nations agency UNESCO states that culture is the â€Å"set of distinctive spiritual, material, intellectual and emotional features of society or a social group and that it encompasses, in addition to art and literature, lifestyles, ways of living together, value systems, traditions and beliefs†. [UNESCO, 2002].It is generally accepted that language is part of culture. It carries culture, thus be influenced by culture. Names includin g family names, which is a part of language, are sure to reflect the distinct culture of the people using it.This paper intends to start from the English and Chinese family names from the perspectives of the origin and order so as to reveal their reflections on their own culture. A family name (in Western contexts often referred to as a last name or surname) is part of a person's name indicating the family to which the person belongs. A family name is the most fundamental and most significant symbols showing the identification of the members of a society. The use of family names is widespread in cultures around the world, which means family names are part of culture.As far as English and Chinese names are concerned, their cultural differences can be shown in the origins of their family names and the different orders of their names so as to make us learn about the development history of a society or a nation and some other aspects of its culture, which is the purpose of this paper in tending to make an analysis between English and Chinese family names from their cultures reflected. 1. Cultural reflections of the origins of family names If we trace back into the origins of Chinese family names, we can see that Chinese family names are closely related to the development history of the Chinese nation.According to legend, family names started with Emperor Fu Xi in 2852 BC. His administration standardized the naming system in order to facilitate census-taking, and the use of census information. For scientific documentation that matrilineal surnames existed in China before the Shang Dynasty (1600-1046 BC) and that â€Å"by the time of the Shang Dynasty they (Chinese surnames) had become patrilinea. † Therefore, what we can learn first is that the ancestors of the Chinese nation came from primitive society.When the Chinese nation went into class society, the emperors had the supreme powers in their hands in awarding lands and fields to those ministers who perfor med meritorious service to their reigns, establishing official positions. Their supreme power was best exemplified in granting a surname to a person when he was alive or after his death. In addition, in feudal societies, the emperors’ names was a taboo on every occasions. The origins of family names also showed that Chinese nation actually is combination of multiple nationalities, which is the same case for the British and American people.As for English family names, 226 ISSN 1911-2017 E-ISSN 1911-2025 www. ccsenet. org/ass Asian Social Science Vol. 6, No. 11; November 2010 they have a relatively short history. Documents indicate that surnames were first adopted among the feudal nobility and gentry, and only slowly spread to the other parts of society. In Britain, hereditary surnames were adopted in the 13th and 14th centuries, initially by the aristocracy but eventually by everyone. By 1400, most English and Scottish people had acquired surnames, but many Scottish and Welsh people did not adopt surnames until the 17th century, or even later.Henry VIII (1491–1547) ordered that marital births be recorded under the surname of the father. The whole process lasted for 500 years. However, English family names differ from Chinese family names in their civilians consciousness, which can be shown in the casual choice of their family names for even a nickname, childhood name like Fox, Stout, Armstrong, Longfellow can be a person's family name. The origins of English family names can show their love for nature, respect for and sentimental attachment to everything in it. English family names like Bird, Lion, Swan, Wood, Wolf, Bush, Flower, Rose and Apple are such examples.Their family names also indicated that English people are characterised by the pursuit for novelty and oddness without an exception of their family names. According to a survey made in 1974, there were as many as 1,280,000 family names in America, among which more than 1/3 were those that had never been used before, which was obviously a result of Americans' unconventional and original personality. 2. Cultural reflections of the order of family names 2. 1 Reflection of perspective feudal history The nations with a name order of family names preceding given names usually have a long feudal history.The Han nationality have a feudal history of more than 2,500 years, which started from the Western Zhou (1066 – 771 BC)or Eastern Zhou (770 – 256 BC) Chinese society to the Opium War in1839. However, the feudal history of those nations with a name order whose given names precede family names is relatively short. Great Britain is a case in point. It only had a short feudal history of several hundred years. From the 9th century to the 11th century, Britain was still on its way to feudalization and there exited a large number of free farmers.It was only after the Norman Conquest of 1066, the feudal system was widely established in Britain. However, only several hu ndred years later, in the 14th century, its feudal system was disintegrated. When it came to the 16th century, the capitalism was widely developed, which directly led to the British Bourgeois Revolution in the 17th century. To sum up, the feudal history of Britain is very short with no more than 500 years, but its capitalism was developed quite early. 2. 2 Reflection of perspective historical traditionThe nations with a name order of family names preceding given names usually have a long feudal history, in which there wasn’t any democratic tradition and everything was determined by the will of the supreme emperors. Therefore, in those nations, given names which represent a person himself can only be put behind family names which stand for home ownership. In China, from the very beginning of family names, they were put before given names and the tradition lasted for more than 2,500 years. In these nations, although the choice of a person’s given names has always been ch anging with the era, the order of names has always been stable.On the contrary, the British and American people had their democratic tradition even in the feudal reign, which made these nations strengthened more on individual roles. Therefore, their given name which stands for the individual himself was always put before their family name which is a representation of their family. 2. 3 Reflection of their historical influence Chinese name order has a direct influence on that of its neighbouring countries like Korea, Vietnam and Japan because of its 5,000 year history of civilization. China's naming system came into being as early as the reign of Emperor Fu Xi.Its neighbouring countries like Korea, Vietnam and Japan either had long been its dependent country or using Chinese characters as their own language. They were greatly influenced by its culture. Similarly, these countries all had a long feudal history, had no democratic tradition, bordered China, used Chinese characters. There fore it was no wonder that they were sure to be influenced Chinese cultures including naming system. However, the English name order was influenced by Roman Republic in its early time. Rome became a republic in about B. C. 510.From then on, the civilians had constant fights against nobility for their rights, which was the origin of their democratic tradition. Because at that time, ancient Rome was the number one civilized country in Europe and in the course of its development it constantly expanded its territories and formed its hegemony in the Mediterranean in the 2nd century B. C. , therefore, its democratic tradition had a great influence on the formation of the national psychology of the whole Europe. Ancient Romans' name was spelled in Latin, and freeman’s name was formed by given name plus tribe or clan name, which was actually their family name.Take the famous Great Emperor Caesar of ancient Rome for example, his name was formed by three parts, that is Caius, Julius Pu blished by Canadian Center of Science and Education 227 www. ccsenet. org/ass Asian Social Science Vol. 6, No. 11; November 2010 and Caesar. With the development of history, the middle name which was one's clan name disappeared with the diminishing power of clan. The Roman name order which strengthened individual role was widely accepted in the Miderterranean with its expansion in this area.The Latin language which was spoken by ancient Romans first replaced other languages in this area but then split into Italian, French, Portugese and Spanish with the fall of the Roman Empire. Because these languages all have Latin origin, it's natural that the name order of the Latin language permeated into their languages. 3. Reflection of current social situation Family names are not only used for addressing people, they also reflect social realities at that time. In China’s ancient Zhou Dynasty, having or not having a family name showed the contradictory relation between the ruling clas s and the working class.Before the establishment of the People's Republic of China, Chinese women followed their husband’s family name by abandoning their original family name, which showed the feudal prejudice against and bondage upon them. After the establishment of the P. R. C. , the social status of Chinese women has been greatly improved and been considered â€Å"half sky†, they can keep their own family name when they get married. However, in England and cultures derived from there, there has long been a tradition for a woman to change her surname upon marriage from her birth name to her husband's last name.From the first known US instance of a woman keeping her birth name, Lucy Stone in 1855, there has been a general increase in the rate of women keeping their original name. This has gone through periods of flux, however, and the 1990s saw a decline in the percentage of name retention among women. As of 2004, roughly 90% of American women automatically assumed t heir husband's surname upon getting married. Even in families where the wife has kept her birth name, parents traditionally choose to give their children their father's family name.Although in America, there was a great change for married women traditionally known as Mrs [Husband's full name] into a modern Mrs [Husband's last name], the incompleteness of women's liberation can still be shown from this. To sum up, family names are not only a sign for a person but reflect culture from different aspects. And a comparison of English and Chinese family names can make us learn about the cultural differences shown from the origins and name orders, which is good for the deepening of the study of English as well as helps to promote the mutual understanding and communication of the East and the West.

Analysis Of John Steinbeck s Jr Essay - 1523 Words

John Ernst Steinbeck, Jr., was conceived on February 27, 1902, in Salinas, California, to a father, John Ernst Steinbeck, who had settled in California not long after the Civil War, and a mother, Olive Hamilton Steinbeck, who was an open teacher. Steinbeck experienced childhood in the wonderful, prolific Salinas Valley, and the clear majority of his critical books and short stories would be set in California. Arranged between the Santa Lucia run and the Gabilan Mountains, this valley in west focal California is verged on the north by Monterey Bay and on the south by San Luis Obispo. Amid his initial years, Steinbeck s mom read to him from books, for example, Treasure Island and Robin Hood. Youthful John grew up listening to the rhythms of the Bible and listening to the enchanting stories of the Round Table from Malory s Le Morte d Arthur. He would return over and over to those early impacts for images and topics. Amid these early years, John s house was agreeable, and his dad regularly drove the kid and his two sisters around the valley where they saw the laborers and field submit their poor shacks. This early impression of the laborers ways of life was added to later recollections when Steinbeck invested energy with these specialists as a grown-up. As a youth, he likewise investigated the hollows and swimming gaps around Salinas and watched the progressions of seasons.

The Problem Of Aging Population - 1111 Words

An aging population is a population with an increased median age due to an increase in life expectancy, accompanied by a decrease in fertility rates. This phenomena is already occurring in other countries, and the United States is expected to undergo a similar demographic shift. The population of citizens aged 65 and over is projected to double in the next few decades, from 43.1 million in 2012, to 83.7 million in 2050, and life expectancy is expected to rise at the same time (Ortman, Velkoff, Hogan, others, 2014). The most important consequence of this is an increase in the percentage of older people from 13% to 20%. An increase of these amount while seemingly insignificant is going to pose a significant burden on the societal support systems set in place to help older individuals. These burden while widespread across different departments, is poised to heavily impact a healthcare climate that is already stretched to the brink. It is essential for adequate preparation to be made in form of public policies that plan for the future. The three most important public policy issues facing the United States are reauthorizing the Older Americans Act, ensuring long-term services and supports, and health coverage for older individuals. The Older Americans Act of 1965 was the first comprehensive federal policy directed towards ensuring increased care for older citizens.
