Piece - Essay Example Although there are other minor scale symphonies attributed to Mozart’s name but there are doubts as to authenticity. However, Symphony Number Forty and Symphony Number Twenty Five are minor scale symphonies both authentically attributed to Mozart (Zaslaw). This paper will explore Mozart’s biography, his Symphony Number Forty in terms of its historical context and its description in order to bring out the nuances in this great musical piece. Mozart’s Life and Times It would not be unjustified to term Mozart as one of the chief canons of Western classical music. Mozart hailed from a period when Europe was teeming with musical activity. Mozart was aided in his musical endeavours at an early age by his family background. Wolfgang Mozart’s father, Leopold Mozart was a practising musician and was quick to realise his son’s talents early on. Mozart was encouraged to take up music at a very early age and was able to compose as early as five years old. The e arliest demonstrations by Mozart were based on the violin and the piano and this left quite a strong impression on the maturing Mozart later. The early works of Mozart tend to revolve around the violin and the piano in large part especially his concertos. ... Mozart moved into the Austrian capital and was soon on his way to fame although Mozart’s financial troubles were far from over. The prolific character and the quality of Mozart’s work were able to project him into the limelight in Vienna and around. However, forbidding circumstances such as the Austro Turk war from the same era proved to be a drain on the fiscal resources of Mozart’s patrons. Consequently, Mozart found himself in fiscal trouble for some time. Eventually, Mozart’s circumstances began to recover but the great composer was soon claimed by a mysterious illness. Wolfgang Mozart died in 1791 at age thirty five. Mozart’s untimely death has been the subject of much speculation over the years and most people consider his early death a setback to Western classical music (Robbins). History of Symphony Number Forty The origin of Symphony Number Forty has been traced to Mozart with authentication. The symphony was noted down by Mozart in his per sonal notebook on July the 25th, 1788. It must be noted that Symphony Number Forty hails from one of the most prolific periods in Mozart’s life. The period in which this symphony was created consisted of only a few weeks but works from this period by Mozart are hailed as masterpieces in their own right (Deutsch). Symphony Number Forty has come under debate for Mozart’s personal viewership. It has been argued that Mozart was never able to hear his Symphony Number Forty performed during his lifetime. The time between the composition of Symphony Number Forty and Mozart’s death is brief so it is argued that Mozart died before any large performances of Symphony Number Forty. However, there are other commentators who reason that Mozart was party to Symphony

Little boy crying by Mervin Morris Essay Example for Free

Little boy crying by Mervin Morris Essay Mervin Morris writes Little boy crying making reference to the relationship between a kid and an adult, who in this case is his father. Throughout the poem different feelings and emotions are expressed, not only of the child but also of the man. The little boy turned his recently relaxed face into tight because of that quick slap struck his guilty father gave him. But despite the fact that the kid took his father as a grim giant because of hitting him, this mans intention was not to make him suffer of pain or anything like that; it was just an unwanted but necessary little punishment, perhaps for a prank or misbehaviour. In fact the father felt guilty and full of sorrow. Mervin introduces an allegory of a rather famous story called: Jack and the beanstalk. The child imagined his father as an ogre, who climbed a huge tree. He hates him. He imagined himself chopping clean the tree hes scrambling down or plotting deeper pits to trap him, as it happens in Jack and the beanstalk. The relationship between the three-year-old full of frustration child and the adult seems to be bursting of complications because the kid is quite capricious and the man has to punish him, so that he learns not to do whatever he wants without evaluating the consequences before. But he cannot understand, not yet how his easy tears affect his father who is wishing to curb boys sadness. Even though an ogre can punish you, you know that he loves you and that you have to learn the lessons from him, because you know, very deep inside, that ogre is your father. That last sentence can summaries the moral of the poem. This particular poem uses words to make the reader feel he or she is seeing it, or being part of it: the quick slap struck, this last sentence is composed of monosyllabic words that imitate the sound of the hit. Another example of this trying the reader to feel part of the poem is the use of the you; it is a kind of conversation between the writer and the reader. Other images that facilitate this process are made by the use of words or phrases suggesting movement or sound, like chopping and scrambling down. But in this poem is not all about the kid, and his feelings, the other character has a very important role. He has to pretend being something is not; behind that mask there is a man who suffers the situation more that the kid, but he has to be seen as a strict authority, as any parent must. This poem reflects nothing but the truth of an ordinary relationship between any father and his son during the growing and maturing process of the kid; but it does not end there: in the last paragraph, which is also the last line, there is a nine words long sentence emphasized by being left alone, that carries a moral in it: you must not make a plaything of the rain. This is a metaphor that could be translated as: you must not cry just because (the rain represents the tears).

INTRODUCTION: We can have integrated a sensor, which has electronics and the transduction element together on one silicon chip. This complete system can be called as system-on-chip .The main aim of integrating the electronics and the sensor is to make an intelligent sensor, which can be called as smart sensor. Smart sensors then have the ability to make some decision. Physically a smart sensor consists of transduction element, signal conditioning electronic and controller/processor that support some intelligence in a single package. Definition: -Smart sensors are sensors with integrated electronics that can perform one or more function, a) logic functions b) two-way communication c) make decisions. 2. USEFULNESS OF SILICON TECHNOLOGY IN SMART SENSOR: There are very convincing advantages of using silicon technology in the construction of smart sensor. All integrated circuits employ silicon technology. A smart sensor is made with the same technology as integrated circuits. A smart sensor utilizes the transduction properties of one class of materials and electronic properties of silicon (GaAs). A transduction element either includes thin metal films, zinc oxide and polymeric films. Integrating electronics circuits on the sensor chip makes it possible to have single chip solution. Integrated sensors provide significant advantages in terms of overall size and the ability to use small signals from the transduction element. Different silicon sensors can be obtained by employing above effects. The silicon sensor can produce output as voltage, current, resistance or capacitance. Output format can be analog or digital. Suitable signal conditioning circuits along with processor can easily be designed using silicon technology. The presence of controller or processor in smart sensor has lead to corrections for different undesirable sensor characteristics, which include input, offset and span variations, on linearity and cross sensitivity. As these are carried out in software, no additional hardware is required and thus calibration becomes an electronic process. Signal conversion effects: Signal Domain Examples (Measured) Examples(Physical Effects in silicon) Radiant Signals Light Intensity, polarization Photovoltaic-effect, photoelectric effect Mechanical Signals Force, pressure, flow, vaccum Piezo-resistivity Thermal Signals Temp, Temp. gradient Seebeck effect Chemical Signals Concentration, pH, toxicity Ion sensitive field effect Magnetic Signals Field intensity, flux density Hall effect 3. General Architecture of Smart Sensor: It is similar to a data acquisition system, the only difference being the presence of complete system on a single silicon chip. In addition to this it has on-chip offset and temperature compensation. BLOCK LEVEL DESIGN CONSIDERATIONS FOR SMART SENSOR: Design choice of smart sensor depends on the specific application for which the sensor is required and also related to specific industry. 4. Importance and Adoption of Smart Sensor: Following are qualities of smart sensor: a) Reduced cost of bulk cables and connectors, b) Remote Diagnostics 4.1 Enhancement of Application:- Smart sensor also enhances the following applications a) Self calibration b) Computation c) Communication d) Multisensing. 4.2 System Reliability: System reliability is significantly improved due to the utilization of smart sensors. One is due to the reduction in system wiring and second is the ability of the sensor to diagnose its own faults and their effect. 4.3 Improvement in Characteristics: There is improvement in following characteristics: Non-linearity, Cross-sensitivity, Offset, Parameter drift and component values. 4.4 Summary of Different Smart Sensors: Some of the smart sensors developed at different research institutes are as follow: Optical Sensor: Optical sensor is one of the examples of smart sensor, which are used for measuring exposure in cameras, optical angle encoders and optical arrays. Similar examples are load cells silicon based pressure sensors. Accelerometer: Accelerometer fabricated at the IBM Research laboratory at San Jose California, which consists of the sensing element and electronics on silicon. The accelerometer itself is a metal-coated SiO2 cantilever beam that is fabricated on silicon chip Integrated Multi-Sensor: Integrated multi-sensor chip developed at the electronics research Laboratory University of California. This chip contains MOS devices for signal conditioning with on chip sensor, a gas flow sensor, an infrared sensing array, a chemical reaction sensor, a cantilever beam, accelerometer, surface acoustic wave vapor sensor, a tactile sensor array and an infrared charge coupled device imager. 5. Distributed Smart Sensor System: A distributed smart sensor system consists of a network backbone, on which reside many nodes. Nodes may be loosely classified as either sensor nodes or controller nodes. Sensor nodes are those, which tend to send data to the network, and controller nodes are those, which tend to gather data from the network. A prototypical smart sensor node consists of three elements: a physical transducer, a network interface, and a processor/memory core. The transducer senses the physical quantity being measured and converts it into an electrical signal. Then the signal is fed to an A/D converter, and is now ready for use by the processor. The processor will perform some signal processing on the data, and depending on how it is programmed, may send the resulting information out to the network. Network transactions are handled by the network interface block. Note that these are only functional definitions and that MEMS technology potentially allows all three blocks to be implemented on a single die. A prototypical controller node consists of processor/memory, a network interface, and input/output devices for communicating with human users. It is used to collect information from the sensor nodes, to program the sensor nodes, and to provide feedback to the user. Placing all the sensors on a common network bus enables plug and play ease of installation. That is, no new wires have to be routed to accommodate new nodes.

Specific Application Of Smart Sensor In Medical Field : The Anaesthesia Supervision: Actually, the essential difficulty of anaesthesia supervision results of the fact that, each characteristic signal (adequate ventilation of lungs, adequate circulation, and intra cranial pressure) is assessed separately. Consequently, it is difficult for the anesthesiologist to evaluate the patients conditions. Moreover, he should able to distinguish equipments dysfunction of a real variation of the patient state. So propose a new architecture for anaesthesia supervision, based on concept of smart sensor. The Contribution of This System Are As Follows:- 1. The elaboration of a rate order from the trend curve of pressure measure and precedent rate.2. The supervision of the difference between the intracranial pressure and mean arterial pressure.

Smart Dishwasher Controller:Current dishwashers enable the user to choose cycle selection, heat selection, and a start delay. Our Smart Controller will remove the cycle options by utilizing a turbidity sensor. The Smart Controller will interface with two modules: the control panel and the dishwasher hardware. Based on user inputs of heat and delay, the controller will send control signals to the proper dishwasher components. The addition of new sensors allows a more accurate pre-wash cycle that can rinse the dishes as long as necessary to remove the loose grit before starting the main cycle. This saves time, energy, and waterafter all, even if the pre-wash cycle actually takes LONGER to run, the user will not have to rewash dishes!It will have inputs both from the user and from onboard sensors; the micro controller that will process the information and provide the appropriate instructions to operate the dishwasher; an amplification circuit to provide the correct signal voltage level to operate the various loads. With the use of a turbidity sensor and a microprocessor, we can take advantage of knowing that the dishes are clean. This will allow us to change the dishwasher operation from static cycles to dynamic cycles. This will undoubtedly result in more efficient wash cycles. 8. Smart Valve Controller: Fig. No. 9 Smart Valve Controller The Smart Valve Controller mounts to a valve solenoid quickly and easily- without screws, drills or additional wires. This rugged product is fully submersible and resists all moisture intrusion in water, mud and debris as deep as 12 feet. Operating off a single 9-volt battery thats guaranteed to provide power through a full season. Its also a breeze to program, with an easy to read and understand LCD display instead of cumbersome buttons and knobs. For isolated sites or power-restricted areas, and for the special needs of drip zones, the new Hunter Smart Valve Controller is your single-station solution. 9. CONCLUSION Smart sensors are becoming a considerable part of various fields such as industries, medical, defense. Silicon plays an important role in development of smart sensors. Still a lot of research is required to get benefits of smart sensors. We recognize that Home Automation is the wave of future. Smart Dishwasher controller gives future vision of Automatic Smart control system. Smooth advantage of smart controller can be sensed by practical example of smart valve controller.

Advertising, Food and Children :: Expository Exemplification Essays

Advertising, Food and Children "Peanut, peanut butter and jelly." Advertising has an impact on its audience. From songs to logos to characters, food product advertisers must keep in mind their audiences. Competition is the force which causes advertisers to target children. Children are targeted through the use of cute phrases, animated characters, and toys in these competitive advertisements. Many types of food have a phrase associated with them. Commercials use these phrases to implant their product into the audiences memory. Goldfish crackers are an example of one these products. "I love the fishes `cause their so delicious..." This is the theme to a well known commercial which advertises Pepperigde Farm goldfish crackers. Children sing the phrase over and over throughout the entirety of the commercial. By the time the commercial ends the line and product are inevitably stuck in a persons mind. The commercial says "... and my mom says that's okay", which implies to children that their parents will allow them to eat this snack. Another example of a product with an addicting phrase is Oscar Meyer bologna. "My bologna has a first name its O-S-C-A-R..." Instead of this song selling the product itself, its aim is to sell the brand. The Oscar Meyer company has had auditions for the next Oscar Meyer child. Again, their goal is to sell their brand. The company also has another product with a catchy song, Oscar Meyer hot dogs. "I wish I were an Oscar Meyer wiener..." The stress of this phrase is also the brand. Oscar Meyer commercials use children to sing these songs and like the goldfish commercial, the song has been imprinted into a persons memory be the end of the commercial. Both companies goal is to sell their product. By targeting children, whole families are then targeted. Competition between companies with similar products, is the reason phrases are used. If one company can create a phrase that everyone will know and remember, they are one step closer to winning the race. Animated characters are also a medium used to target children. Animation has been the way which companies from Disney to Cartoon Network, capture the attention of children everywhere. Tony the Tiger is the spokesperson for Kellogg's frosted flakes.

Beautillion & church and school

When I look back unto my life, I find that it has – short as it may be – so far been a good one. Divided between church and school, and backed up by my home, I understand quite well that I am luckier than most youths my age. I don't do drugs – beyond the legally allowed ones, such as coffee – I don't drink. I don't have an unstable situation is my household, nor am I close to a dropout, as many youths are.I've found God and was able to implement Him into my life as an advisor and someone to talk to on an everyday basis. I don't meet with discrimination much, not more than any of my peers.And yet I find there is something left unfulfilled in my life. So I look back upon myself and the places I inhabit, and recollect, to move forward with the improved knowledge of myself. My home has always been good to me. I have always had a great relationship with my parents, who were an inspiration for the many things I do. Without their support, I would never have been able to gather the determination to study the saxophone long enough to be an active member in a marching band. They are also the ones who taught me compassion and to look at the elderly in a different, kind light.This has led to one of the most enjoyable experiences of my life: using my ability to create music to help the elderly in their retirement homes. This is a daily school of tolerance and kindness for me, and I can with all honesty say that I have learned much from them and with their help. My parents have also always been there for me, through thick and thin, and for that I am eternally grateful. School is a very important part of my life. It gives me the information I need to live well. I am a good student, my grades are above average, but the more I learn, the more I see that education I am getting is really rather basic.Since I study more than I am supposed to by normal school standards, I can see that there is much more to be learned than high school gives us. There are obvious gaps in our education, and I think they create part of the problems this country is having. I try to alleviate the unfortunate side effects of early specialization through my own efforts, but this is rather difficult. I can only hope that when I get into college the situation will be somewhat amended by the possibility of free research and the aid of experienced scholars.Still, school is a great learning experience for me, because, even despite the lack of serious understanding of the natural and social sciences, it is a great place to adapt to adult life and learn how to gradually take responsibility. I try to make the most of school, but am anxious to gain the greater opportunities of college. My church life is a good one, as well. I am a Baptist, and love my congregation for the principle of sola scriptura. Every single Baptist must think for himself and commune with God directly.I know I have a living, personal God looking after me, and I confide in him. When I look at m embers of other confessions I feel sadness, because I know that very many of them are mistaken and are led down the darker paths of life, and quite possibly into the bowels of Satan. I try to help them best I can, through intelligently questioning them on their morality and faith in God. I try not to act too strongly in my desire to help, as many people consider such actions an infringement of their personal space, even though I am simply demonstrating how Baptism helps in living a good life.However, I am happy in the lap of my Church, and I try to lead others to it by example. After all, if we do not help these people, who will tell them that they are in the grave danger of sin? I take pride in getting the chance to help those who strayed from Jesus’s flock. My life may seem perfect from this essay. I am very well-rounded education-wise; I have a good home, and a direct hotline with God. Yet there is something always left unfulfilled. I do not mean the failures of life †“ those I have long learned to accept and to listen to as mere messages.Perfection is lonely, and, though I have most anything I really want, I do not know what to desire further. I have reached a stage in personal development when just helping myself is not enough. A new need opens up in me, slowly and steadily. It is the need to help others. What use is there for good in my own life if my best friend is troubled? How worthy am I if my mother cries at night, for any reason? These questions haunt me constantly, and drive to begin a new stage – life as a servant to the people.

Lehman Brothers Failure Questions Essay

Having taken part to the events occurring in this scenario only in a few occasions, and as the ultimate guarantee of rescue, the FED,in conjunction with FDIC and the Office of the Comptroller of the Currency, made decisions aimed to save those institutions, for instance AIG, Fannie Mae and Freddie Mac, whose failure would have had a greater impact on financial system’s wealth and perspectives of recovering from the crisis were reliable. This was the main reason for declining any proposal of action in favor of Lehman. Some argued that the company’s bankruptcy was an intentional choice rather than a â€Å"genuine error†, aimed to induce the restoration of higher degrees of financial discipline. However, had the government disposed a plan in favor of Lehman Brothers, this would have prevented investors from losing faith towards financial institutions, the financial system from freezing and economy from carrying the weight of the crisis Notwithstanding, further attempts to save Lehman Brothers did not came to completion for several reasons, not only due to Government stillness, but the giving out of other financial actors i. . Bank of America and Barclays. In an ultimate analysis is thus important to consider that the â€Å"unfair† practices were not carried on by the sole Government, but by all financial institutions acting in the system as a whole: every actor placed a risky bet, whose consequences seem difficult to be addressed to just one responsible. Do you think that the U. S. government should have allowed Lehman Brothers to fail? Although Lehman Brothers was the fourth-largest U. S. investment bank, it was seen by many analysts as the weakest of Wall Street’s biggest firms. It is plausible therefore to think that the government willfully took the decision to let it go bankruptcy, in the purpose to restore a certain degree of indipendence from the market, and serving as threat for other institutions preventing them from adopting hazardous behaviours. The government decision of non-intervention had immense costs both in terms of financial losses inflicted to the credit market operators and institutions, and of lost in confidence in the market itself, that eventually turned into terror and paralyzed the credit market worldwide. Indeed investors’ confidence in th market and general concerns about the security of the banks continued to plumb during Lehman Brothers’ stock value erosion and afterwards. Nonetheless, consequences from Lehman Brothers’ bankruptcy had spread in a broader sense affecting all clusters of stakeholders: for instance, it could be mentioned the forced lay off of up to 1,500 people, which amounted to about 6 percent of Lehman’s work force. With hindsight, the decision of the US Government to allow such a giant as Lehman to fail is difficult to support, especially considering the devastating negative impact it had in a long-term perspective. Almost no objection that it should have been a critical decision to take at that time. It indeed brought the evidence that the financial market needed a shock, which unveiled some crucial problems and send a clear message to the banking system, proving that â€Å"too big to fail† companies were likely to face collapse as well, though no one would have believed this before. Many experts argue that when the government bails out a private financial institution it creates a problem called â€Å"moral hazard,† meaning that if the institution knows it will be saved, it actually has an incentive to take on more risk, not less. What do you think? Moral hazard, or, in other words, the willing of companies to act recklessly, bearing large risk exposure, has the consequential effect of distorting competition, thus mitigating risk perception and allowing excessive risk-taking, which is ultimately transferred from financial institutions to the society as a whole. This had been a controversial argument , largely discussed in the light of the financial crisis of 2008. The core of the debate was to what extent did moral hazard caused the crisis, and to what extent did government’s guarantees of rescuing perpetuated an hazardous behavior among market players. The moral-hazard argument is not only due to eventual interventions from governments, but is increasingly being considered by expertise as an inner element of a company’s strategic policy, drawing the shape of the decision making process in the interest of the company itself. However, corporate decisions are rather made in the interests of individuals than for the company as a whole, which causes a loose the connection between those interests and the company’s long-term health assumption. The possibility to gain short term benefits, at a relatively low cost, leads to reckless behavior regardless of eventual bails out from governments, with long term costs that hardly find responsibles to pay them back. One key factor is indeed limited liability, which allows investors and executives, ultimately liable for companies’ decisions, to enjoy the benefits of their risk-taking, while eventually limiting their exposure. The Government is responsible for contrasting moral hazard practices and maintaining investors’ confidence in the stability of both financial and economic activity, ensuring that the system don’t suddenly shut down in a panic. It can happen that, indeed, the expectation of further intervention from regulators and politicians may be an incentive for hazardous practices itself. However, moral hazard is an intrinsic disease of corporate strategies, thus of the financial market, whose antidote only relatively depends on government rescuing hand upon financial institutions.
