Spanish And French Monarchial Beliefs - The Escorial And Versailles :: essays research papers
The palace of Versailles was built by Louis XIV of France (1643-1715), and the Escorial was built by Philip II of Spain (1556-1598). By examining the aerial and frontal facades of these two palaces, it may be seen that there were many similarities and differences between the two kingsââ¬â¢ perception and practice of monarchy. Each king set his own goals for his life, and concluded as to how a monarch ought to behave. Both Louis XIV and Philip II had religious duties to pay attention to, organized the distribution of power in their respective kingdoms, communicated with other countries and entities through war and diplomacy, raised militaries, and made plans for the expansion of their own beliefs, thoughts and practices. Aside from these aspects of the two kingsââ¬â¢ beliefs and practices of monarchy, the architecture of their palaces reflected their ideals, or personal beliefs, and the interpretation made by the painters of the palaces reflects the attitudes of the two kings t oward life. The role of the king to the public during the reigns of Louis XIV of France and Philip II of Spain were not predetermined, so each king created for himself what he thought monarchy ought to be. Louis XIV and Philip II were both absolutists, and believed that they should be the supreme rulers of France and Spain, respectively. However, Louis XIV did not want to be a national symbol serving no legitimate purpose. He wished to control the military, economy, foreign affairs, and the administration of the kingdom and of justice. He believed that the king of France should be the best that France has to offer- being served by even the most powerful lords of France. Conversely, Philip II thought of himself as Catholic first, and king of Spain second. Opposite to Louis XIV, Philip II preferred to sit in the Escorial and pray, pour over records, and live more as a monk than as Louis XIVââ¬â¢s conception of a king. Philip II never wanted to take much of an active part in the administration o f his kingdom, except for the times when he wanted to use some of his various powers. However, after he had used it for a while (waging war, raising taxes, etceteras) he would let it lay dormant and return to his documents. Nor did Philip II ever wish to control most of the Spanish economy. The parts that he did control were ones that directly affected himself or his revenues, so vital in order to keep his army of immense proportions.

Plot Analysis of a Rose for Emily
ââ¬Å"In this world, nothing is certain but death and taxes. â⬠This quote by Benjamin Franklin is a mirror to Emilyââ¬â¢s story as it begins with her death and then the reader is abruptly brought into the tax remission she received after the death of her father. This interesting yet confusing vignette is about a girl named Emily Grierson and her inconsiderate relation with the town, a man she loved, Homer Baron, and her Father. For Readers of Faulkner, it is truly apparent that his stories do not follow the pattern of the conventional beginning to the end of the story. This method of disorderly sequence of events along with the descriptive style tends to lead this story as if we are realistically present in the town. It also keeps the reader attentive for the upcoming rising action present throughout the story. This leaves the reader questioning or predicting the actual outcome, he/she interprets it well after all is being read. It is a southern gothic styled story, a tragic story told by an anonymous narrator that speaks on behalf of the townââ¬â¢s people, but he/she is not related to the protagonist of the story, Emily. Emily throughout the story is perceived as an object to the reader rather than a character because her side of the story is not personally expressed by her. This type of narration grasps the readersââ¬â¢ level of curiosity as they are not given access into her perception about her life. In the story, two essential elements of life have been readily repeated throughout; taxes and death . Death being the main theme was not accepted or comprehended by Emilyââ¬â¢s mindset. This story explains the taxes submission issues faced my Emily. The rest of the story revolves around hatred and death in Emilyââ¬â¢s chaotic life from which she was once guarded from the rest of the cruel world. The story begins with the death of Miss Emily; readers are presented to Miss Emilyââ¬â¢s fight and struggle, with her antagonist time, through the situation she is living in. As it seems the protagonist, Emily tries to pause the time around her to save her loved ones, trying to avoid certainty, death, and thus fails to do so. Miss Emily appearance represents a past era, an era in which she masks her privacy in, declining the changing time being passed by. She was raised by her father that is why she was encapsulated by silence, inability to believe in reality and inability to happy life; she was the result of her environment. The most minute yet meaningful sentence described in the whole story is in Section II, ââ¬Å"So she vanquished them, horse and foot, just as she had vanquished their fathers thirty years before about the smell. â⬠(Faulkner 22) . The use of the definite article mentioned in the sentence abruptly brings about a sense of suspense. It merely shows that it was not just ââ¬Å"a smellâ⬠but ââ¬Å"the smellâ⬠. As brought by the narrator it is justified that the townââ¬â¢s people were familiar of such odor occurring in Emilyââ¬â¢s house before. The narrator grants a significance to the smell because ââ¬Ëthe smellââ¬â¢ would had never put such an impact as an ââ¬Å"aâ⬠smell would have. When Miss Emily refused to give her fatherââ¬â¢s dead body away, it started to decompose, spreading a pungent odor; same odor was present once again. As for a reader it foreshadows events to come. The way Faulkner presented the story and designed the structure, interpersonal conflicts increased between Emily and the society. The town is just not a setting but is a character in the story. It is the setting of an old era that held tight to old beliefs and moral values of the South. Social class in the story holds great significance. Faulkner when describes the character ââ¬Å"Tobeâ⬠, points out the status setting of that era. Tobe was disrespected and was considered a person with no values throughout. For example, Judge Stevens called him as, ââ¬Å"â⬠¦that nigger of hersâ⬠¦Ã¢â¬ (Faulkner, p. 22); showing racism present during that time frame. They disgraced the minorities and disrespected their physical existence and social status. People had pride over unnecessary ephemeral high standards that displayed discrimination and inequality. In the story as cited previously, social class was significant in demonstrating dehumanization of blacks but also demonstrating differences in the rich and the poor. Miss Emily is judged for a having romance with a low class, poor citizen of that society, Homer baron. The following sentence affiliates townsââ¬â¢ people response towards Emilyââ¬â¢s one and only intimate relationship with Homer. Poor Emilyâ⬠, the whispering began. ââ¬Å"Do you suppose itââ¬â¢s really so? â⬠, they said to one another, (Faulkner, p. 23). The townspeople felt pity upon her relationship with Homer, as in the eyes of the townspeople a barrier of status was set up, only the deserving or the affluent ones were allowed. Homer was a labor whereas; Miss Emily belonged to a respected rich family. Dist inguishing their class differences, Homer was way beyond Miss Emilyââ¬â¢s league, an image set in the eyes of the townspeople. Moreover secrets are kept throughout the story, plotted as such so they are left to the reader to discover them. For example, Faulkner uses the above-mentioned technique in the following line, ââ¬Å"â⬠¦so they were not surprised when the smell developedâ⬠(Faulkner, p. 22). The prediction here is that the pungent yet familiar smell developed in Emilyââ¬â¢s house due to decaying of a dead body; which for sure is kept as a secret until the end. Emilyââ¬â¢s further more surreptitious actions can be observed through the following lines said by the narrator, ââ¬Å"We did not say she was crazy then. We believed she had to do that. We remembered all the young men her father had driven away, and we knew that with nothing left, she would have to cling to that which had robbed her, as people willâ⬠(Faulkner, p. 22). The disguise truth here is that Miss Emily was indeed crazy, and the upcoming horror is that she could be psychotic enough to repeat the same action, holding on to Homerââ¬â¢s dead body. Barron's fate is linked in this passage as Faulkner provides the reader with a hint of death. The themes of class, race and status are widespread throughout the story, Faulkner repeatedly addresses those themes. â⬠The town of Jefferson is isolated by race, extremely class and social status conscious people because people disliked and abhorred a women of a high class walking with a low social standing man. In closure ââ¬Å"A Rose for Emilyâ⬠is a captivating short story of a lady who refuses to adopt the changing world and order of society around her. Her denial of certainty and death gives us an understanding of depth of emotions that a girl encounters throughout her life. It is felt that these disturbed actions would not have taken place if she was placed in a different time and setting. She gave us the impression of a silently killed character that was only physically living. Even though we could not pass through her door we still encountered much information about how and why she was. Faulkner flawlessly points out the broader ideas, including the complexities of northern and southern places at that time frame, complexities of an altering world order, disappearing lands of courtesy and nobility, and rigid social responsibilities of a women.

Architecture Timeline of Important Historic Periods
When did Western architecture begin? Long before the magnificent structures of ancient Greece and Rome, humans were designing and constructing. The period known as the Classical Era grew from ideas and construction techniques that evolved centuries and eons apart in distant locations. This review illustrates how each new movement builds on the one before. Although our timeline lists dates related mostly to American architecture, historic periods do not start and stop at precise points on a map or a calendar. Periods and styles flow together, sometimes merging contradictory ideas, sometimes inventing new approaches, and often re-awakening and re-inventing older movements. Dates are always approximate ââ¬â architecture is a fluid art. 11,600 B.C. to 3,500 B.C. ââ¬â Prehistoric Times Stonehenge in Amesbury, United Kingdom. Jason Hawkes/Getty Images Archaeologists dig prehistory. Gà ¶bekli Tepe in present day Turkey is a good example of archaeological architecture. Before recorded history, humans constructed earthen mounds, stone circles, megaliths, and structures that often puzzle modern-day archaeologists. Prehistoric architecture includes monumental structures such as Stonehenge, cliff dwellings in the Americas, and thatch and mud structures lost to time. The dawn of architecture is found in these structures. Prehistoric builders moved earth and stone into geometric forms, creating our earliest human-made formations. We dont know why primitive people began building geometric structures. Archaeologists can only guess that prehistoric people looked to the heavens to imitate the sun and the moon, using that circular shape in their creations of earth mounds and monolithic henges. Many fine examples of well-preserved prehistoric architecture are found in southern England. Stonehenge in Amesbury, United Kingdom is a well-known example of the prehistoric stone circle. Nearby Silbury Hill, also in Wiltshire, is the largest man-made, prehistoric earthen mound in Europe. At 30 meters high and 160 meters wide, the gravel mound is layers of soil, mud, and grass, with dug pits and tunnels of chalk and clay. Completed in the late Neolithic period, approximately 2,400 BC, its architects were a Neolithic civilization in Britain. The prehistoric sites in southern Britain (Stonehenge, Avebury, and associated sites) are collectively a UNESCO World Heritage Site. The design, position, and inter-relationship of the monuments and sites, according to UNESCO, are evidence of a wealthy and highly organized prehistoric society able to impose its concepts on the environment. To some, the ability to change the environment is key for a structure to be called architecture. Prehistoric structures are sometimes considered the birth of architecture. If nothing else, primitive structures certainly raise the question, what is architecture? Why does the circle dominate mans earliest architecture? It is the shape of the sun and the moon, the first shape humans realized to be significant to their lives. The duo of architecture and geometry goes way back in time and may be the source of what humans find beautiful even today. 3,050 B.C. to 900 B.C. ââ¬â Ancient Egypt The Pyramid of Khafre (Chephren) in Giza, Egypt. Lansbricae (Luis Leclere)/Getty Images (cropped) In ancient Egypt, powerful rulers constructed monumental pyramids, temples, and shrines. Far from primitive, enormous structures such as the Pyramids of Giza were feats of engineering capable of reaching great heights. Scholars have delineated the periods of history in ancient Egypt. Wood was not widely available in the arid Egyptian landscape. Houses in ancient Egypt were made with blocks of sun-baked mud. Flooding of the Nile River and the ravages of time destroyed most of these ancient homes. Much of what we know about ancient Egypt is based on great temples and tombs, which were made with granite and limestone and decorated with hieroglyphics, carvings, and brightly colored frescoes. The ancient Egyptians didnt use mortar, so the stones were carefully cut to fit together. The pyramid form was a marvel of engineering that allowed ancient Egyptians to build enormous structures. The development of the pyramid form allowed Egyptians to build enormous tombs for their kings. The sloping walls could reach great heights because their weight was supported by the wide pyramid base. An innovative Egyptian named Imhotep is said to have designed one of the earliest of the massive stone monuments, the Step Pyramid of Djoser (2,667 B.C. to 2,648 B.C.). Builders in ancient Egypt didnt use load-bearing arches. Instead, columns were placed close together to support the heavy stone entablature above. Brightly painted and elaborately carved, the columns often mimicked palms, papyrus plants, and other plant forms. Over the centuries, at least thirty distinct column styles evolved. As the Roman Empire occupied these lands, both Persian and Egyptian columns have influenced Western architecture. Archaeological discoveries in Egypt reawakened an interest in the ancient temples and monuments. Egyptian Revival architecture became fashionable during the 1800s. In the early 1900s, the discovery of King Tuts tomb stirred a fascination for Egyptian artifacts and the rise of Art Deco architecture. 850 B.C. to A.D. 476 ââ¬â Classical The Pantheon, A.D. 126, Rome, Italy. Werner Forman Archive/Heritage Images/Getty Images (cropped) Classical architecture refers to the style and design of buildings in ancient Greece and ancient Rome. Classical architecture shaped our approach to building in Western colonies around the world. From the rise of ancient Greece until the fall of the Roman empire, great buildings were constructed according to precise rules. The Roman architect Marcus Vitruvius, who lived during first century B.C., believed that builders should use mathematical principles when constructing temples. For without symmetry and proportion no temple can have a regular plan, Vitruvius wrote in his famous treatise De Architectura, or Ten Books on Architecture. In his writings, Vitruvius introduced the Classical orders, which defined column styles and entablature designs used in Classical architecture. The earliest Classical orders were Doric, Ionic, and Corinthian. Although we combine this architectural era and call it Classical, historians have described these three Classical periods: 700 to 323 B.C. ââ¬â Greek. The Doric column was first developed in Greece and it was used for great temples, including the famous Parthenon in Athens. Simple Ionic columns were used for smaller temples and building interiors. 323 to 146 B.C. ââ¬â Hellenistic. When Greece was at the height of its power in Europe and Asia, the empire built elaborate temples and secular buildings with Ionic and Corinthian columns. The Hellenistic period ended with conquests by the Roman Empire. 44 B.C. to A.D. 476 ââ¬â Roman. The Romans borrowed heavily from the earlier Greek and Hellenistic styles, but their buildings were more highly ornamented. They used Corinthian and composite style columns along with decorative brackets. The invention of concrete allowed the Romans to build arches, vaults, and domes. Famous examples of Roman architecture include the Roman Colosseum and the Pantheon in Rome. Much of this ancient architecture is in ruins or partially rebuilt. Virtual reality programs like Romereborn.org attempt to digitally recreate the environment of this important civilization. 527 to 565 ââ¬â Byzantine Church of Hagia Eirene in the First Courtyard of the Topkapà ± Palace, Istanbul, Turkey. Salvator Barki/Getty Images (cropped) After Constantine moved the capital of the Roman empire to Byzantium (now called Istanbul in Turkey) in A.D. 330, Roman architecture evolved into a graceful, classically-inspired style that used brick instead of stone, domed roofs, elaborate mosaics, and classical forms. Emperor Justinian (527 to 565) led the way. Eastern and Western traditions combined in the sacred buildings of the Byzantine period. Buildings were designed with a central dome that eventually rose to new heights by using engineering practices refined in the Middle East. This era of architectural history was transitional andà transformational. 800 to 1200 ââ¬â Romanesque Romanesque Architecture of the Basilica of St. Sernin (1070-1120) in Toulouse, France. Anger O./AgenceImages courtesy Getty Images As Rome spread across Europe, heavier, stocky Romanesque architecture with rounded arches emerged. Churches and castles of the early Medieval period were constructed with thick walls and heavy piers. Even as the Roman Empire faded, Roman ideas reached far across Europe. Built between 1070 and 1120, theà Basilica of St. Sernin in Toulouse, France is a good example of this transitional architecture, with a Byzantine-domed apse and an added Gothic-like steeple. The floor plan is that of the Latin cross, Gothic-like again, with a high alter and tower at the cross intersection. Constructed of stone and brick, St. Sernin is on the pilgrimage route to Santiago de Compostela. 1100 to 1450 ââ¬â Gothic The Gothic Cathedral of Notre Dame de Chartres, France. Alessandro Vannini/Getty Images (cropped) Early in the 12th century, new ways of building meant that cathedrals and other large buildings could soar to new heights. Gothic architecture became characterized by the elements that supported taller, more graceful architecture ââ¬â innovations such as pointed arches, flying buttresses, and ribbed vaulting. In addition, elaborate stained glass could take the place of walls that no longer were used to support high ceilings. Gargoyles and other sculpting enabled practical and decorative functions. Many of the worlds most well-known sacred places are from this period in architectural history, including Chartres Cathedral and Paris Notre Dame Cathedral in France and Dublins St. Patricks Cathedral and Adare Friary in Ireland. Gothic architecture began mainly in France where builders began to adapt the earlier Romanesque style. Builders were also influenced by the pointed arches and elaborate stonework of Moorish architecture in Spain. One of the earliest Gothic buildings was the ambulatory of the abbey of St. Denis in France, built between 1140 and 1144. Originally, Gothic architecture was known as the French Style. During the Renaissance, after the French Style had fallen out of fashion, artisans mocked it. They coined the word Gothic to suggest that French Style buildings were the crude work of German (Goth) barbarians. Although the label wasnt accurate, the name Gothic remained. While builders were creating the great Gothic cathedrals of Europe, painters and sculptors in northern Italy were breaking away from rigid medieval styles and laying the foundation for the Renaissance. Art historians call the period between 1200 to 1400 the Early Renaissance or the Proto-Renaissance of art history. Fascination for medieval Gothic architecture was reawakened in the 19th and 20th centuries. Architects in Europe and the United States designed great buildings and private homes that imitated the cathedrals of medieval Europe. If a building looks Gothic and has Gothic elements and characteristics, but it was built in the 1800s or later, its style is Gothic Revival. 1400 to 1600 ââ¬â Renaissance Villa Rotonda (Villa Almerico-Capra), near Venice, Italy, 1566-1590, Andrea Palladio. Massimo Maria Canevarolo via Wikimedia Commons, Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) A return to Classical ideas ushered an age of awakening in Italy, France, and England. During the Renaissance era architects and builders were inspired by the carefully proportioned buildings of ancient Greece and Rome.à Italian Renaissance master Andrea Palladio helped awaken a passion for classical architecture when he designed beautiful, highly symmetrical villas such as Villa Rotonda near Venice, Italy. More than 1,500 years after the Roman architect Vitruvius wrote his important book, the Renaissance architect Giacomo da Vignola outlined Vitruviuss ideas. Published in 1563, Vignolas The Five Orders of Architecture became a guide for builders throughout western Europe. In 1570 Andrea Palladio used the new technology of movable type to publish I Quattro Libri dell Architettura, or The Four Books of Architecture. In this book, Palladio showed how Classical rules could be used not just for grand temples but also for private villas. Palladios ideas did not imitate the Classical order of architecture but his designs were in the manner of ancient designs. The work of the Renaissance masters spread across Europe, and long after the era ended, architects in the Western world would find inspiration in the beautifully proportioned architecture of the period. In the United States its descendant designs have been called neoclassical. 1600 to 1830 ââ¬â Baroque The Baroque Palace of Versailles in France. Loop Images Tiara Anggamulia/Getty Images (cropped) Early in the 1600s, an elaborate new architectural style lavished buildings. What became known as Baroque was characterized by complex shapes, extravagant ornaments, opulent paintings, and bold contrasts. In Italy, the Baroque style is reflected in opulent and dramatic churches with irregular shapes and extravagant ornamentation. In France, the highly ornamented Baroque style combines with Classical restraint. Russian aristocrats were impressed by the Palace of Versailles, France and incorporated Baroque ideas in the building of St. Petersburg. Elements of the elaborate Baroque style are found throughout Europe. Architecture was only one expression of the Baroque style. In music, famous names included Bach, Handel, and Vivaldi. In the art world, Caravaggio, Bernini, Rubens, Rembrandt, Vermeer, and Velà ¡zquez are remembered. Famous inventors and scientists of the day include Blaise Pascal and Isaac Newton. 1650 to 1790 ââ¬â Rococo Catherine Palace Near Saint Petersburg, Russia. Saravut Eksuwan/Getty Images During the last phase of the Baroque period, builders constructed graceful white buildings with sweeping curves. Rococo art and architecture is characterized by elegant decorative designs with scrolls, vines, shell-shapes, and delicate geometric patterns. Rococo architects applied Baroque ideas with a lighter, more graceful touch. In fact, some historians suggest that Rococo is simply a later phase of the Baroque period. Architects of this period include the great Bavarian stucco masters like Dominikus Zimmermann, whoseà 1750 Pilgrimage Church of Wies is a UNESCO World Heritage site. 1730 to 1925 ââ¬â Neoclassicism The U.S. Capitol in Washington, D.C. Architect of the Capitol By the 1700s, European architects were turning away from elaborate Baroque and Rococo styles in favor of restrained Neoclassical approaches. Orderly, symmetrical Neoclassical architecture reflected the intellectual awakening among the middle and upper classes in Europe during the period historians often call the Enlightenment. Ornate Baroque and Rococo styles fell out of favor as architects for a growing middle class reacted to and rejected the opulence of the ruling class. French and American revolutions returned design to Classical idealsà ââ¬â including equality and democracy ââ¬â emblematic of the civilizations of ancient Greece and Rome. A keen interest in ideas of Renaissance architect Andrea Palladio inspired a return of Classical shapes in Europe, Great Britain, and the United States. These buildings were proportioned according to the classical orders with details borrowed from ancient Greece and Rome. In the late 1700s and early 1800s, the newly-formed United States drew upon Classical ideals to construct grand government buildings and an array of smaller, private homes. 1890 to 1914 ââ¬â Art Nouveau The 1910 Hà ´tel Lutetia in Paris, France. Justin Lorget/chesnot/Corbis via Getty Images Known as the New Style in France, Art Nouveau was first expressed in fabrics and graphic design. The style spread to architecture and furniture in the 1890s as a revolt against industrialization turned peoples attention to the natural forms and personal craftsmanship of the Arts and Crafts Movement. Art Nouveau buildings often have asymmetrical shapes, arches, and decorative Japanese-like surfaces with curved, plant-like designs and mosaics. The period is often confused with Art Deco, which has an entirely different visual look and philosophical origin. Note that the name Art Nouveau is French, but the philosophyà ââ¬â to some extent spread by the ideas of William Morris and the writings of John Ruskin ââ¬â gave rise to similar movements throughout Europe. In Germany it was called Jugendstil; in Austria it was Sezessionsstil; in Spain it was Modernismo, which predicts or event begins the modern era. The works of Spanish architect Antoni Gaudà (1852-1926) are said to be influenced by Art Nouveau or Modernismo, and Gaudi is often called one of the first modernist architects. 1895 to 1925 ââ¬â Beaux Arts The Paris Opera by Beaux Arts Architect Charles Garnier. Francisco Andrade/Getty Images (cropped) Also known as Beaux Arts Classicism, Academic Classicism, or Classical Revival, Beaux Arts architecture is characterized by order, symmetry, formal design, grandiosity, and elaborate ornamentation. Combining classical Greek and Roman architecture with Renaissance ideas, Beaux Arts architecture was a favored style for grand public buildings and opulent mansions. 1905 to 1930 ââ¬â Neo-Gothic The Neo-Gothic 1924 Tribune Tower in Chicago. Glowimage/Getty Images (cropped) In the early 20th century, medieval Gothic ideas were applied to modern buildings, both private homes and the new type of architecture called skyscrapers. Gothic Revival was a Victorian style inspired by Gothic cathedrals and other medieval architecture.à Gothic Revival home design began in the United Kingdom in the 1700s when Sir Horace Walpole decided to remodel his home, Strawberry Hill. In the early 20th century, Gothic Revival ideas were applied to modern skyscrapers, which are often called Neo-Gothic. Neo-Gothic skyscrapers often have strong vertical lines and a sense of great height; arched and pointed windows with decorative tracery; gargoyles and other medieval carvings; and pinnacles. The 1924 Chicago Tribune Tower is a good example of Neo-Gothic architecture. The architects Raymond Hood and John Howells were selected over many other architects to design the building. Their Neo-Gothic design may have appealed to the judges because it reflected a conservative (some critics said regressive) approach. The facade of the Tribune Tower is studded with rocks collected from great buildings around the world. Other Neo-Gothic buildings include the Cass Gilbert design for the Woolworth Building in New York City. 1925 to 1937 ââ¬â Art Deco The Art Deco Chrysler Building in New York City. CreativeDream/Getty Images With their sleek forms and ziggurat designs, Art Deco architecture embraced both the machine age and ancient times. Zigzag patterns and vertical lines create dramatic effect on jazz-age, Art Deco buildings. Interestingly, many Art Deco motifs were inspired by the architecture of ancient Egypt. The Art Deco style evolved from many sources. The austere shapes of the modernist Bauhaus School and streamlined styling of modern technology combined with patterns and icons taken from the Far East, classical Greece and Rome, Africa, ancient Egypt and the Middle East, India, and Mayan and Aztec cultures. Art Deco buildings have many of these features: cubic forms; ziggurat, terraced pyramid shapes with each story smaller than the one below it; complex groupings of rectangles or trapezoids; bands of color; zigzag designs like lightening bolts; strong sense of line; and the illusion of pillars. By the 1930s, Art Deco evolved into a more simplified style known as Streamlined Moderne, or Art Moderne. The emphasis was on sleek, curving forms and long horizontal lines. These buildings did not feature zigzag or colorful designs found on earlier Art Deco architecture. Some of the most famous art deco buildings have become tourist destinations in New York City ââ¬â the Empire State Building and Radio City Music Hall may be the most famous. The 1930 Chrysler Building in New York City was one of the first buildings composed of stainless steel over a large exposed surface. The architect, William Van Alen, drew inspiration from machine technology for the ornamental details on the Chrysler Building: There are eagle hood ornaments, hubcaps, and abstract images of cars. 1900 to Present ââ¬â Modernist Styles De La Warr Pavilion, 1935, Bexhill on Sea, East Sussex, United Kingdom. Peter Thompson Heritage Images/Getty Images The 20th and 21st centuries have seen dramatic changes and astonishing diversity. Modernist styles have come and goneà ââ¬â and continue to evolve. Modern-day trends include Art Moderne and the Bauhaus school coined by Walter Gropius, Deconstructivism, Formalism, Brutalism, and Structuralism. Modernism is not just another styleà ââ¬â it presents a new way of thinking. Modernist architecture emphasizes function. It attempts to provide for specific needs rather than imitate nature. The roots of Modernism may be found in the work of Berthold Luberkin (1901-1990), a Russian architect who settled in London and founded a group called Tecton. The Tecton architects believed in applying scientific, analytical methods to design. Their stark buildings ran counter to expectations and often seemed to defy gravity. The expressionistic work of the Polish-born German architect Erich Mendelsohn (1887-1953) also furthered the modernist movement. Mendelsohn and Russian-born English architect Serge Chermayeff (1900-1996) won the competition to design the De La Warr Pavilion in Britain. The 1935 seaside public hall has been called Streamline Moderne and International, but it most certainly is one of the first modernist buildings to be constructed and restored, maintaining its original beauty over the years. Modernist architecture can express a number of stylistic ideas, including Expressionism and Structuralism. In the later decades of the twentieth century, designers rebelled against the rational Modernism and a variety of Postmodern styles evolved. Modernist architecture generally has little or no ornamentation and is prefabricated or has factory-made parts. The design emphasizes function and the man-made construction materials are usually glass, metal, and concrete. Philosophically, modern architects rebel against traditional styles. For examples of Modernism in architecture, see works by Rem Koolhaas, I.M. Pei, Le Corbusier, Philip Johnson, and Mies van der Rohe. 1972 to Present ââ¬â Postmodernism Postmodern Architecture at 220 Celebration Place, Celebration, Florida. Jackie Craven A reaction against the Modernist approaches gave rise to new buildings that re-invented historical details and familiar motifs. Look closely at these architectural movements and you are likely to find ideas that date back to classical and ancient times. Postmodern architecture evolved from the modernist movement, yet contradicts many of the modernist ideas. Combining new ideas with traditional forms, postmodernist buildings may startle, surprise, and even amuse. Familiar shapes and details are used in unexpected ways. Buildings may incorporate symbols to make a statement or simply to delight the viewer. Philip Johnsons ATT Headquarters is often cited as an example of postmodernism. Like many buildings in the International Style, the skyscraper has a sleek, classical facade. At the top, however, is an oversized Chippendale pediment. Johnsons design for the Town Hall in Celebration, Florida is also playfully over-the-top with columns in front of a public building. Well-known postmodern architects include Robert Venturi and Denise Scott Brown; Michael Graves; and the playful Philip Johnson, known for making fun of Modernism. The key ideas of Postmodernism are set forth in two important books by Robert Venturi. In his groundbreaking 1966 book, Complexity and Contradiction in Architecture, Venturi challenged modernism and celebrated the mix of historic styles in great cities such as Rome. Learning from Las Vegas, subtitled The Forgotten Symbolism of Architectural Form, became a postmodernist classic when Venturi called the vulgar billboards of the Vegas Strip emblems for a new architecture. Published in 1972, the book was written by Robert Venturi, Steven Izenour, and Denise Scott Brown. 1997 to Present ââ¬â Neo-Modernism and Parametricism Zaha Hadids Heydar Aliyev Centre, 2012, Baku, Azerbaijan. Christopher Lee/Getty Images Throughout history, home designs have been influenced by the architecture du jour. In the not far off future, as computer costs come down and construction companies change their methods, homeowners and builders will be able to create fantastic designs. Some call todays architecture Neo-Modernism. Some call it Parametricism, but the name for computer-driven design is up for grabs. How did Neo-Modernism begin? Perhaps with Frank Gehrys sculpted designs, especially the success of the 1997 Guggenheim Museum in Bilbao, Spain. Maybe it began with architects who experimented with Binary Large Objects ââ¬â BLOB architecture. But you might say that free-form design dates back to prehistoric times.

The Great Depression began with a catastrophic collapse of stock market prices in the New York stock exchange in October 1929. During the next few years stock prices continued to fall. The only thing we have to fear is fear itself. ââ¬Å"The result was drastically falling output and drastically rising unemployment; by 1932, U.S. manufacturing output had fallen to 54 percent of its 1929 level, and unemployment had risen to between 12 and 15 million workers, or 25-30 percentâ⬠¦show more contentâ⬠¦As the ranks of former slaves shrank, so did the possibility of preserving the inside view of slavery that their reference provided. ââ¬Å"The proslavery justification of the peculiar institution alleged that it was a benevolent system and that the position of the slave was more secure than that of the Northern wage earner. The slave, according to George Fitzhugh, one of the most vigorous of the proslavery propagandists, was happy as a human can be.â⬠(Fed). Stock prices continued to rise and by fall that year had reached levels that could not be justified by future earnings. The stock market finally burst, as investor began to dump shares en masse. Millions of shares ended up being worthless and those investors who had bought stocks were wiped out completely. ââ¬Å"The American economy entered an ordinary recession during the summer of 1929, as consumer spending dropped and unsold goods began to pile up, slowing production.â⬠(The). Many struggled to keep jobs and business. The core of the problem was the massive disparity between the countryââ¬â¢s productive capacity and the ability of people to consume. Innovations in productive techniques during and after the war raised the output of industry beyond the purchasing capacity of u.s. Farmers wage earners. The saving of the affluent and middle class increased far beyond the possibilities of investment. ââ¬Å"By 1933 the value of stock on the New York Stock Exchange was less than a fifth of what it had been at its peakShow MoreRelated Bruce Springsteins I Aint Got No Home (In This World Anymore) and the Great Depression827 Words à |à 4 Pages Bruce Springsteins I Aint Got No Home (In This World Anymore) and the Great Depression The 1930s was the time of The Great Depression, which resulted in drastic changes.

Claustrophobia free essay sample
The Symptoms, Causes, and Treatments of a Popular Phobia Phobias have been a common part of the world since the beginning of time. As most people know, a phobia is ââ¬Å"a special form of fear whichâ⬠¦ cannot be explained or reasoned away [and] is beyond voluntary controlâ⬠(Marks 3). There are hundreds upon thousands of phobias in the world. However, one of the most common phobias is called claustrophobia. As most know and Ronald Doctor explains, ââ¬Å"Claustrophobia is the fear of closed places, such as closets, subways, tunnels, telephone booths, elevators, small rooms, crowds, or other enclosed or confined spacesâ⬠(104). Claustrophobia has known symptoms, causes, and treatments. Claustrophobia has known symptoms. Psychologists have found some common and some specific symptoms that go along with claustrophobia and its victims: If a person suffering from claustrophobia suddenly finds themselves in an enclosed space, they may have an anxiety attack. Symptoms can include: Sweating, accelerated heart rate, hyperventilationâ⬠¦ shaking, light-headedness, nausea, fainting, [and] fear of actual harm or illness (Better Health). The common symptoms of claustrophobia are the same symptoms that one would get in the event of an anxiety attack. Nevertheless, there are also specific symptoms that go along with stronger claustrophobics. For example, if a claustrophobic person were to go into a room that is small or a little too crowded, he or she would recognize his or her exits and stand near them just in case an escape would be needed. The claustrophobic may avoid times of the day when there is a lot of traffic so that he or she does not get surrounded by all the vehicles. If he or she goes into a building that has the choice of stairs and an elevator, he or she would avoid the small space of the elevator, no matter how many stairs he or she would have to go up. Claustrophobics just really cannot stand small amounts of space in general; it is too frightening for them. There are not too many symptoms of Claustrophobia itself, but there are enough to tell whether or not a person has it. Not only have psychologists found out the symptoms of claustrophobia, but they have also figured out some of the possible causes. Claustrophobia has known causes. Psychologists have found some possible causes for those who have this unfortunate phobia. However, everyone is different, so it may vary. The following are some of the more common causes of claustrophobia that they have found in people: Environmental and biological factors may both be involved. Some people are born with a personality style that may lend itself to the person becoming claustrophobic. Others may learn a cautious style depending on experiences they have, the way others react to them, or the behaviors they see in their parents and others. Biological and chemical processes in the brain may also play a part. (Berger). The causes for this phobia are unique to each of those who are cursed with it. Everyoneââ¬â¢s brains are different, so everyone will have picked up this phobia in different ways. Some learn it from their parents, while others have come by it by being locked in their room for being a bad child; itââ¬â¢s barely the same. There are, however, some treatments that people can indulge in to help them get over their fear of enclosed spaces. Treatments for claustrophobia are now available to the public. Scientists have found different remedies to help people come to terms with their claustrophobia and learn how to overcome it. Some of the treatments do not even involve medications. The list of treatments are as follows: flooding, counter-conditioning, modeling, cognitive behavior therapy, and, of course, medications. The first, flooding, is when the claustrophobic person is exposed to their fear until their anxiety passes. Once they realize that they were unharmed, their phobia will sometimes go away. The second treatment, counter-conditioning, is what the claustrophobic does when he or she is too scared to try flooding. This is a technique where ââ¬Å"the person is taught to use specific relaxation and visualization techniques when experiencing phobia-related anxiety. The phobic trigger is slowly introduced, step-by-step, while the person concentrates on attaining physical and mental relaxation (Better Health). â⬠The result for this is the same as flooding. The third treatment is modeling, which is when the person watches other people defeat their fears and they have a want to imitate the brave behavior of the other people. The fourth, or cognitive behavior therapy, is a way of teaching the claustrophobic different ways to think and also a way to change the attitudes that make them feel the fear of enclosed spaces. Last, but not least, is the use of medications. The more common medications that are used are tranquilizers, anti depressants, and beta-blockers of most any kind. It seems that most people would choose the easy route of medications, but medications can become addictive. So, it is always good to have a few alternative methods to curing phobias. Claustrophobia may be a deep-rooted fear, but it can be overcome with the correct help. Claustrophobia is common and annoying, but, because of what psychologists have learned about it, people are more aware of where it comes from and how to make it go away. Those who have claustrophobia can now begin trying to defeat their fear of enclosed spaces. They can get out into the world and enjoy the company of others, even when enclosed in a space that seems a little too small or crowded. They can discover what the cause of their fear is and then how to treat that fear with the correct method for them. If they are having troubles getting over the fear, they can always go to the doctor and inquire about getting some help from medications. Also, learning that they are not the only people in the world who experience extreme fear can help them cope with their own phobia. The symptoms, causes, and treatments for claustrophobia have been discovered and spread throughout the world.

Questions: 1.Provide an Opinion regarding which antenna types will become the dominant players in the future of medium- and long-distance wireless links. 2.Compare and Contrast the multiplexing techniques CDMA and FDMA in the area of wireless networking? 3.A local engineering group ask you to present your finding of the most recent advanced wireless technologies. Research these technologies in details and pay specific attention to how they are used as well their strengths and weakness. Answers: 1.Different antenna, such as yagi, horn, and cellular antennas, etc. has different merits. Research these technologies in details and pay specific attention to how they are used as well their strengths and weakness. Provide an opinion regarding which antenna types will become the dominant players in the future of medium- and long-distance wireless links. Antennas can be defined as the main segments of any electrical circuit as they give interconnecting joins amongst transmitter as well as free space or among the free space and recipient. The various types of antennas are discussed as following: Yagi Antennas - Yagi antennas are economical as well as viable. It can be built with at least one reflector components and at least one component. Yagi reception could be made by utilizing one reflector, a determined collapsed dipole dynamic component, and the mounted horizontal polarization in the forward methodology. A single driven component i.e dipole, proliferates RF vitality; components that are placed instantly before and behind the determined component re-transmit RF energy in as well as out of phase by upgrading and impeding the flag, individually. The components are known as parasitic components; the component behind the determined component is known as the reflector, while the components before the determined component are called executives. These antennas have beam widths of 30 to 80 degrees and also can give well in abundance of 10 dBi inactive gain. This is powerful antenna that points in one direction. But in case, we need signal in other direction, we can use more yag i antennas. (Agarwal, T., 2015). Horn Antennas - These antennas falls in microwave category. These antennas are appropriate for frequencies in which waveguides are the standard support strategy, as they comprise of a waveguide whose walls are flared outside to frame a structure of megaphone. These antennas are widely utilized at microwave frequencies when there is moderate requirement of power. It is moderately used. The best examples are delivered by making the horn length huge as compared with the gap width, yet this must be picked as an exchange with the general volume possessed. A typical utilization of horn antenna is as the sustain component for explanatory dish reception tool in satellite frameworks. (Ingale, C. Ingale, T., 2008). Cellular Antennas - Cellular antennas could be utilized as a part of conjunction with a controlled flag sponsor, like inline amplifier or repeater or associated specifically to the wireless device with a mobile phone connector link or coax connector. The reception of cell signal is adversely influenced by many elements that includes blocks like structures, vehicles, slopes or trees and also separate from the phone tower. Utilizing a mobile phone radio wire can decrease issues with dropped calls and blurs the signal while enhancing range of service, voice quality and access. Putting a radio wire on the rooftop keeps the dividers and siding from constricting phone signal and limits the impact of different hindrances in cell tower. Eg: In a vehicle, up to 90% of the phone signal is hindered by the vehicle edge and its glass. A mobile phone receiving wire mounted on the external surface of the vehicle extraordinarily expands the phone signal. (WPSantennas cellular reception solutions, 20 17). 2.CDMA - Code Division Multiple Access transmits over the whole recurrence go accessible. It doesn't allot a particular recurrence to every client on the communication network. This technique, called multiplexing. (Christensson, P., 2006). CDMA utilizes analog to digital transformation (ADC) by combining with its spread spectrum. It digitize its audio input in binary components. The recurrence of the transmitted signal varies so it can be caught just by a collector whose recurrence reaction is modified with a similar code, so it takes after precisely alongside the transmitter recurrence. There possibilities are trillion of frequency sequencing that upgrades security and makes cloning troublesome. The CDMA channel is ostensibly 1.23 MHz wide. CDMA systems utilize a plan is also known as delicate handoff, which limits signal separation as a handset goes starting with one cell then onto the next. Combination of advanced and spread-range modes underpins various number of signs per unit data transfer capacity as analog modes. CDMA is good with other cell innovations; this takes into consideration across the nation roaming. (Rouse, M., 2015). FDMA - FDMA partitions the mutual medium transfer speed into singular channels. The modulated subcarriers transmit each sub channel. For example - cable network system. It uses single coax cable that communicate many channels of video or audio programming to homes. The persuade link has a valuable data transfer capacity from around 4 MHz to 1 GHz. This data transfer capacity is divided into 6-MHz wide channels. This method is utilized as a part of fiber optic communication frameworks. A fiber optic link has huge transmission capacity that can be subdivided to give FDMA. Unique aviation telemetry frameworks utilized a FDMA framework to oblige numerous sensor information on a solitary radio station. (Frenzel, L., 2013). 3.The accepting and transmitting reception antenna with the mediating medium play out the capacity of the transmission line in wire communication framework. Communication in long distance in the high recurrence area depends on the impression of the radio waves from the ionosphere. The aftereffect of this can be transmission or its reception from a few to numerous degree over the horizon that is contingent upon the distance amongst stations and stature of the reflecting layer. At the point when a reception tool emanates more emphatically in some direction, it is said to have directivity. The more the radiation is gathered in a specific heading, the more noteworthy will be the field quality created toward that path for given measure of aggregate power emanated. Waves that are transmitted from the radio wire at angle that is made above the horizontal point. This angle is then reflected by the earth and consolidate with, or meddle with the immediate waves that are emanated at points over the horizontal. The resultant vertical radiation design is controlled by the impedance which relies on the introduction of radio wire as for earth, the stature of the antenna, the character of ground and course properties of real antenna. (High frequence antennas., n.d). Drawbacks The main drawbacks of antennas are its reliability and interference in its signal. It is susceptible in broadcasting over long distances. In these devices, the occurrence of co-channel is more. (Naval postgraduate school, 2003). References Agarwal, T. (2015). Heres a Quick Way to Know about Different Types of Antennas.
