Analogue-digital and Digital-analogue conversion Essay

Analogue-digital and Digital-analogue conversion - Essay Example music record (Dallet and Silva, 2005). Analogue signals are usually continuous and variable in nature are they can be represented by a variable wave. On the other hand, digital signals are multi-level in the sense that it only varies after some predetermined time hence it is easier to predict its future processes. The essence of analogue to digital is to convert the data contained in an analogue signals into a more presentable form without altering the initial content (Pelgrom, 2013). There are numerous methods that are in use when it comes to analogue to digital conversion the type of techniques that is chosen depends on the requirements of the user. For instance, is the user wants a quick conversion technique then he/she will opt for a faster ADC, alternatively if he/she wants an accurate conversion process then he will indeed opt for an accurate ADC. However, in all case the same principle is utilised to conduct the conversion process. The sequence of bits in a typical digital representation infers a number that whereby each bit has twice the weight of the next bit in the sequence, for instance; bn-1, bn-2†¦Ã¢â‚¬ ¦b0 (Shoop, 2001). There are different procedures for A/D transformation, including flash, half blaze, integrator, delta sigma or modulator, progressively rough guess, and voltage-to-recurrence. A flash ADC applies the info in parallel to numerous quick comparators whose edges are just as dispersed all through the sought data voltage range, ordinarily 1V. At any minute, all the comparators that have edges underneath the info voltage are on, and the rest are off. Half-streak simple to advanced converters focus their yield code by digitally joining the aftereffects of two successively performed lower-determination streak changes. An integrator is an ADC whose return system speaks to the standard estimation of the voltage information more than a given time

School Life Essay Example for Free

School Life Essay Then BOOM my alarm clock goes off to wake my brother and I up to get ready for school, but this was all put to the side by our mother coming in to the room telling us that she would have to work a few extra hours. Wake your but up! Is what I yelled to my brother as I had always did he consistently showed himself to be the lazy one who would just breeze through life without a care in the world. He replied back with the bad morning breath, â€Å"Leave, me, alone its only 6:30 school doesn’t start until 7:30. Me as usual I got up pulled him out of bed until he hit the floor then started my routine to get ready for the day’s events. Oh yeah my name is Gerard by the way. I carried myself across the dimly lit hall towards the bathroom. As I flicked on the light switch, I first noticed this hair pick still stuck in the side of my head. I immediately grabbed it and started to fix my hair. As I stand in front of the mirror looking back at my own reflection, wondering why, does school start this early in the morning, I grabbed the toothbrush and toothpaste and began to a make it happen. My brother’s name is Joel, and he could care less of his appearance, because he always thought that he was God’s gift to the ladies. Most of his attire consisted of whatever he felt like grabbing out of the closet or the first thing he could get his hands on. He didn’t care if he was all wrinkled, his excuse was that they’ll be gone throughout the day plus now one would notice them anyway because that’s how he rolled. You would have thought that he just came from summer camp playing rugby with a few of his friends before school started. As he came into the bathroom besides me to wash up and get ready, I could always here him saying thanks for getting me up too, knowing that being the older sibling I couldn’t just let him be late for school besides our mother would have killed me. As I look at the clock I notice that we are right on schedule, its 7:00 and time to wake my sister Latoya, she’s in middle school and does not experience the rush that my brother and I go thru being that the two of us share a room and sometimes wrestle to get around to what we need to be done. The time is now 7:10, and it’s time for us to leave the house headed for school since we live only a quarter of a mile away from the school we can pretty much toss a couple of rocks a few times and we’re there. The only downside is that sometimes we get too complacent living so close to the school that we end up thinking there’s more time and end up cutting it close to getting to class on time or worse being late and end up with detention. As we get to school they are still selling breakfast its usually something simple like garlic cheesy bread or the cinnamon sugar rolls that are so delicious. But we cannot stand in line and enjoy them today because the first school bell rings and that signifies things need to get closed out and you need to put your thinking caps on. As we exited the cafeteria it was 7:25 and the start of the school day and the final bell rings at 1:50. Joel and I always knew that we would see each other at our lunch period odd as it seems I was a senior and he was a sophomore, but hey, that’s how the schedules came out. We couldn’t control the outcomes of what we wanted to do we could always find some sort of time to throw a wise crack at one another.

Sustainable design

Sustainable design Introduction Sustainable design is the philosophy of designing physical and conceptual objects, the built environment and services to fulfil the principles of economic, social, and ecological sustainability. Sustainable designs are more commonly seen nowadays because of the rise in environmental issues like greenhouse effect and global warming. With reference to a survey done by Autodesk Inc, the results indicate that mechanical engineers expect to see an increase in sustainable design work in 2010. â€Å"According to survey results, designs that use less energy or reduce emissions remain the most important sustainable technology practice, while manufacturing processes that use less energy and natural resources were also a priority.† There are several factors to consider when creating a sustainable design. They are ecological sustainability, built environment, economic sustainability and social responsibility. Ecological sustainability deals with issues regarding the natural Ecological Sustainability environmentally-friendly designs Built Environment man-made design, indoor and outdoor design Economic Sustainability marketability of the design Social Sustainability -cohesion, place and people Social Responsibility Ethics is fundamentally a practical matter. It is concerned with how we should live, how we should treat other people and the world around us. It is how we should act in a moral and responsible manner. Sustainable designs are strongly encouraged because it is beneficial to our environment. It is each and every one of our duties and responsibilities to protect and take care of our environment. Achieving Sustainable Design Sustainable designs are achieved through sensitive designs, for example, energy efficiency. Sensitive designs include good contextual studies of the surroundings, factors like site location, weather and local culture. The choice of material for the design is also an important factor as well. It is encouraged that renewable resources are used for building materials as it is environmentally-friendly. An example of a sustainable design is the EDITT (Ecological Design in the Tropics) Tower (Figure 1) in Singapore. It adopts many climatic responsive techniques: â€Å"wind walls† to direct wind to internal spaces, solar panels, mechanically joined connections between building components to facilitate recycling, rainwater collection, sewage composting and grey-water reuse. The tower has well-planted facades and vegetated terraces which is approximately about 3800 sq meters, almost about half of the gross usable area of the building As seen from the layout plan , the greenery are planted at the edges of each level. The placement of the vegetation within the tower at different levels correspond to the microclimates of each individual sub-zone at the tower. Human Nature Relationship A good sustainable design should also relate people with the natural environment. Human and nature interaction are encouraged in architectural designs by creating openings to create views, allowing people to be in touch with the natural surroundings. Man activities that destroy the environment and consume energy are meaningless because they contribute little to our well beings and the quality of life. Recycled furniture is therefore becoming a very popular choice. Wood and glass are good examples of recycled material. However, recycled furniture could also mean to reuse old and unwanted items. Figure 4 shows a recycled chair made of compact discs. As information are conveniently stored into thumb drives and computers in modern days now, old and burned compact discs are not wanted anymore. Alternative suggestions to reuse the discs may include coasters, but the recycled chair in figure 4 is a good way to reuse loads of discs all at once. However, the comfortability of the chair is another issue. Figure 5 is a coffee table made of bicycle wheel. Bent and spoiled bicycle wheel may be useless to some but after some alterations, the faulty wheels could be turned into a useful piece of furniture. Cons of Sustainability The aim of sustainable design is to accommodate peoples current demands and needs of the present without compromising the ability of future generations to accomodate their own needs. Many of the current processes the modern world chooses to obtain and use our natural resources are short-sighted. Companies looking to make a profit right away can cause long term damage to the environment when they do activities for example, cutting down too many trees or produce pollutants. However, sustainable design would require huge amount of time, money and research to find out which methods of production would damage the environment the least. This is the major reason why people are hesitant to support sustainable development. Case Study The Marcus Beach House designed by BARK Design Architects in Australia has a coastal setting, providing the owner with a relationship with the landscape and sensitive surrounding environment. This site explores filtering natural breezes, lightness, layers of transparency and integrating between indoor and outdoor spaces within dynamic patterns of light and shadow, being a simple frame to enable a contemporary sustainable lifestyle. The Marcus Beach House Design uses open concept where there are a lot of flexible spaces available. Walls are made retractable to allow better air ventilation. As seen from figures 5 and 6, the blue arrows indicated the wind flow directions through windows and void spaces. Such architectural designs made use of available natural surrounding elements, for example the wind and the sunlight. Therefore, the energy consumption is greatly reduced. Conclusion Sustainability in designs is greatly beneficial to our environment and hence strongly encouraged. The factors to consider when creating a sustainable design are ecological sustainability, built environment, economic sustainability and social responsibility. Everyone is responsible for the natural environment that they are living in and hence should play a part in protecting our Earth. Sustainable designs can be created through sensitive designs with reference to the site context to achieve energy efficiency.

Pales Paradigm and Lamarcks Paradigm Essay -- Philosophy, Scientific

According to Tomas Kuhn, â€Å"normal science means research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice† (Pajares ). The achievements that Kuhn defines as paradigms help the scientific community develop a scientific method to resolve puzzles. Particular puzzles that paradigms fail to solve and eventually lead to paradigm shifts are called anomalies. Since Kuhn first introduces the relations of these three terms to philosophy of science in â€Å"The Structure of Scientific Revolutions,† scientific communities have improved their understandings of science and society. By describing two different paradigms of Paley and Lamarck on organic change in the early nineteenth century, Kuhn’s paradigms can further demonstrate its efficient way to articulate scientific assumptions and understand the scientific change. In William Paley’s paradigm, the world is perfectly designed by a benevolent God who purposefully created everything and â€Å"superadded pleasure to animal sensations† (RP 47 ). Paley strongly believes the existence of a God who is wise and benevolent enough to create everything on earth with happiness and a purpose. For Paley, science is a tool to complement the greatness of religion and prove the importance of Design (RP 46). In order to support his paradigm, Paley illustrates the contrivance and work of God in nature with the methodological assumption of First Cause (the belief in the existence of God) and Final Cause (the belief that a God creates an object with a purpose). Additionally, the metaphysical assumption of a close, active God underlies the paradigm as a premise that influences e... ...d for centuries. On the other hand, Lamarck challenges this traditional thought and brings about a new theory that contains controversial ideas. With this provocative attitude, he demonstrates his intent to challenge the achievements for centuries and cause scientific change leading to paradigm shifts. Comparing Paley’s and Lamarck’s paradigms show how Kuhn’s paradigm can be used to compare and explain different paradigms. With the examples of observation, assumptions, and anomalies, two paradigms clearly demonstrate their ability to solve puzzles as well as their potential influence on understanding of society. The Kuhn’s paradigm model helps understand the changes in scientific perspectives and the course of European society. The use of this paradigm model can provide an opportunity to explain current scientific paradigms and assist in developing new paradigms.

Women Characters in The White Queen (Wars of the Roses)

Women Characters in The White Queen (Wars of the Roses) In June, 2013, BBC One debuted a 10-part series, The White Queen, a depiction of the Wars of the Roses seen through the eyes of key women, and based on a series of historical novels by Philippa Gregory. The White Queen refers to Elizabeth Woodville, and The White Queen is the title of Gregorys first book in the series that is being adapted. Dont expect it to be exactly history but Gregory has respect for history, and that will likely show through in the series as well, even though there will be lots of poetic license taken. The other books in the series are The Red Queen  (about Margaret of Anjou), The Kingmakers Daughter  (about Anne Neville),The Lady of the Rivers (about Jacquetta of Luxembourg), The White Princess  (about Elizabeth of York)  and  The Kings Curse  (about Margaret Pole.) The sequel BBC One series,  The White Princess,  debuted in 2017. You can also see this as something of a prequel to the popular series, The Tudors. Elizabeth Woodville was the grandmother of King Henry VIII, featured in that series. Here are some of the women youll likely encounter in the series, and some of their interconnections youll see why Gregory called the series on the Wars of the Roses The Cousins War many close relatives found themselves on opposite sides. Many of the key characters traced their ancestry to the sons of Edward III of England, or to other kings of England. The White Queen and Her Family Elizabeth Woodville (1437 - 1492), widow of Sir John Grey who was on the Lancastrian side in the Wars of the Roses, and who was killed in the battle at St. Albans. The legend of her meeting with Edward IV under an oak tree by the side of a road is a very early one. That they secretly married and thwarted the marriage plans for Edward being made by Edwards uncle, the Earl of Warwick (known as the Kingmaker), is historical. One of her sons by John Grey was an ancestor of Lady Jane Grey.Jacquetta of Luxembourg, mother of Elizabeth Woodville, was a descendant of Englands King John. Her father was a French count. Jacquettas first husband was the brother of Henry V. She had no children by that first marriage, but at least ten by her second to Richard Woodville. She was accused during her lifetime of using witchcraft.Elizabeth of York (1466 - 1503), eldest daughter of Elizabeth Woodville and Edward IV, became the queen consort of Henry VII and mother of Henry VIII, Mary Tudor and Margaret T udor. Catherine or Katherine Woodville(~1458 - 1497), sister of Elizabeth Woodville, who married advantageously thanks to her connection to her sister the Queen. She became the Duchess of Buckingham and the Duchess of Bedford.Mary Woodville (~1456 - 1481), another sister of Elizabeth Woodville, was able to marry the heir to the Earl of Pembroke through her sisters connections. Her father-in-law was executed by Warwick, the Kingmaker.Cecily of York (1469 - 1507) was the second surviving daughter of Edward IV and Elizabeth Woodville. (An older sister, Mary of York, died in 1482, before she could be married.) Edward tried to marry her to the Scottish royal heir, then to that heirs brother, but Edward died before that could be complete. Then Cecilys marriages were arranged and unarranged by the next two kings, Richard III (her uncle) and Henry VII (her brother-in-law). The Kingmaker and His Family Richard Neville, 16th Earl of Warwick, (1428 - 1471) was a powerful figure in the drama of the Wars of the Roses. He used his female family connections to advantage, including gaining the Warwick title itself through his wifes inheritance. He was called the Kingmaker, as his presence and that of the troops he could muster would make a difference in which king won. Lady Anne Beauchamp (1426 - 1492), Countess of Warwick, wife of the Kingmaker, mother of Anne Neville and Isabella Neville. She was an heiress, inheriting the Warwick titles because no male heirs remained, and bringing them to her husband. She was descended on the maternal side from King Edward III and the powerful Despenser family.Cecily Neville (1415 - 1495), was the aunt of the Kingmaker. She was the mother of Edward IV as well as of George, Duke of Clarence, and Richard, Duke of Gloucester, was married to Richard, Duke of York, who was the heir of Henry VI and his protector during his minority and during one or more bouts of insanity. Both Cecily and her husband were descendants of King Edward III of England and his wife, Philippa of Hainault. Cecilys mother was a daughter of John of Gaunt and Katherine Swynford.Anne Neville (1456 - 1485), daughter of Richard, Duke of York, called the Kingmaker, who was a nephew of Cecily Neville. She first married Edward of York, son of Henry V I of England, but after his early death, married Richard, Duke of Gloucester, the future Richard III, brother of Edward IV (and son of Cecily Neville). Richard and Anne were first cousins once removed. Isabella Neville (1451 - 1476), sister of Anne Neville, and thus daughter of the Kingmaker and great niece of Cecily Neville. She was also known as Isabel. She married George, Duke of Clarence, a younger brother of Edward IV (and older brother of Richard III, Anne Nevilles second husband), and also a son of Cecily Neville. Isabella and George were first cousins once removed. From the House of Lancaster Margaret of Anjou (1429 - 1482), was the queen consort of the Lancastrian king, Henry VI of England, with whom Edward IV contended in the Wars of the Roses. Margaret of Anjou was herself an active Lancastrian leader. Elizabeth Woodville had been a maid of honor serving Margaret of Anjou when she married Sir John Grey.Margaret Beaufort (1443 - 1509) was the Red Queen to Elizabeth Woodvilles White Queen. She was married to Edmund Tudor when she was only 12, and gave birth to his child after he died in Yorkist captivity. That child later became Henry VII. Though she married twice more, she never had more children, and threw her support to her sons cause in the Wars of the Roses. More? These women arent likely to be in the series, except by reference, but are important to the context of the story. Catherine of Valois (1401 - 1437), sister-in-law of Jacquetta, was the queen consort of Henry V of England and mother of Lancaster king Henry VI. She was also the grandmother of Henry VII, the first Tudor king, via her second husband, Owen Tudor. This is the same Henry VII who married Elizabeth Woodvilles daughter, Elizabeth of York. Catherines father was Charles VI of France. She is not likely to make an appearance in The White Queen: she died the year that Elizabeth Woodville was born.Margaret of Burgundy, a sister of Edward IV who was friendly with Edwards new wife Elizabeth Woodville. Margaret was married off to the Duke of Burgundy a few years after Edward became king, and after the Tudor triumph, her home became a haven for Yorkists in exile.Lady Jane Grey was descended from one of Elizabeth Woodvilles sons by her first husband, John Grey, and from one of Elizabeth Woodvilles daughters, Elizabeth of York, by her second husband Edward IV, through Elizabeth of Yorks and Henry VII s daughter Mary Tudor. Margaret Pole (1473 - 1541) was the daughter of Isabella Neville and George, Duke of Clarence. She was a peeress in her own right, and eventually earned the enmity of Tudor King Henry VIII. The Roman Catholic Church beatified her as a martyr in 1886.Elizabeth Tilney (1447 - 1497) was a lady-in-waiting to Elizabeth Woodville. Whether shell appear in the series I doubt, but it would be a subtle foreshadowing of the Tudor era: she was grandmother to both Anne Boleyn and Catherine Howard, second and fifth wives of Henry VIII. One way women often got entangled into the Wars of the Roses: illegitimacy controversies. Learn more about some of those: Birther Controversies and the Wars of the Roses Many of these same women were portrayed in Shakespeares Richard III as well.
