â€Å"The characteristic of sound by which a shrill sound can be distinguished from a grave sound is known as PITCH.†Pitch of sound depends upon the frequency of sound. The greater the frequency, the higher is the pitch and vice versa. It is the pitch of sounds that enable us to distinguished b/w a sound of man and woman or man and dog. Etc. sound of a woman is shrill due to high pitch. Sound of a dog is grave due to low pitch and low frequency.QUALITY OR TIMBERâ€Å"The property of sound by virtue of which we can distinguish between two sounds of the same pitch and the loudness originating from two different musical instruments.† The sound produced by two different instruments is usually complex. It is a mixture of several tones. The tone of lowest frequency is called Fundamental frequency and other tones are known as OVERTONES OR HARMONICS. The loudness of sound depends upon the amplitude of vibration. And pitch determined by its fundamental frequency. Two or more sou nd may have the same loudness and the same pitch but that they may differ in number and relative intensities of overtones. The quality of sound depends upon the wave from of the resultants. Nature has such a great diversity that it is very rare to have some overtones of two persons exactly. So this difference is overtones makes it possible to recognize each sound. This characteristic of sound is called QUALITY. INTENSITY OF SOUNDâ€Å"The intensity of sound is defined as the amount of energy transmitted per second through unit area held perpendicularly in the direction of sound waves.† Intensity of sound = E/t.A OR I = E/t.A Pitch Pitch = frequency of soundFor example, middle C in equal temperament = 261.6 HzSounds may be generally characterized by pitch, loudness, and quality. The perceived pitch of a sound is just the ear's response to frequency, i.e., for most practical purposes the pitch is just the frequency. The pitch perception of the human ear is understood to operate basically by the place  theory, with some sharpening mechanism necessary to explain the remarkably high resolution of human pitch perception. The place theory and its refinements provide plausible models for the perception of the relative pitch of two tones, but do not explain the phenomenon of perfect pitch. The just noticeable difference in pitch is conveniently expressed in cents, and the standard figure for the human ear is 5 cents.Sound quality is typically an assessment of the accuracy, enjoyability, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to the sound or gauge its perceived similarity to another sound. The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, processing and master ing done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it.In some cases, processing such as equalization, dynamic range compression or stereo processing may be applied to a recording to create audio that is significantly different from the original but may be perceived as more agreeable to a listener. In other cases, the goal may be to reproduce audio as closely as possible to the original. When applied to specific electronic devices, such as loudspeakers, microphones, amplifiers or headphones sound quality usually refers to accuracy, with higher quality devices providing higher accuracy reproduction. When applied to processing steps such as mastering recordings, absolute accuracy may be secondary to artistic or aesthetic concerns. In still other situations, such as recording a live musical performance, audio quality may refer to proper placement of microphones around a room to optimally use room acoustics.

Jesus vs Hercules

Myths and Religion are generally presumed to be two entirely different things. Myths are seen as stories shared between groups of people that are part of a cultural identity, while Religion is a belief that a group of people of a cultural identity share. Although they differ in certain aspects, they still hold similarities. Comparable to bible stories, myths have different versions which are both inspirational, as well as entertaining to those who do not believe them to be true. Along with this major similarity, there are parallels to specific stories. Various nurturing aspects of Hercules from Greek mythology, and Jesus Christ from the Bible are similar, including their birth, life and ultimately death in their respective lives. Right from their births, Jesus and Hercules’ lives are comparable. Jesus was born of a virgin mother, Mary, while Hercules was born of Alcmene, who was impregnated by Zeus. Although both their mothers were not virgins, their birth was similar in the sense that they were both half mortal and half god. Jesus and Hercules both had mortal mothers and gods as fathers. They were both raised by other men who played the role of a father in their lives – Joseph for Jesus, and (name) for Hercules. As babies, Jesus and Hercules’ lives were both in danger. Herod, who was the king at the time Jesus was born, wanted him killed as he was afraid Jesus was to be the next king. To solve this, he sent out armies of men to kill every newborn in the city. Jesus was saved when an angel appeared in Joseph’s dream to warn them about the danger. In the case of Hercules, his stepmother was the one that wanted him killed. She was jealous that her husband Zeus slept with multiple women and wanted baby Hercules dead. She let two venomous serpents into his crib, but being the son of Zeus, Hercules was born with great strength, and was able to easily catch and strangle the serpents to death. During their time on earth, Jesus and Hercules lived fairly normal lives as men in their towns. Jesus started to perform miracles in his home town around the age of thirty where as Hercules was always seen as a mighty strong man. Hercules and Jesus were both icons, Jesus the icon of Christianity and Hercules the icon for the Greeks. They both had many followers as young men who seemed to have later been abandoned during times or turmoil and danger. Jesus when he was preaching about God lost many followers as the Pharisees claimed Jesus’ works a cult, where as Hercules lost his followers when cursed by Hera his stepmother in a fit of anger killed his own wife and children. Although many seem to think of Hercules as a redeemer and saviour, Hercules did not save the world in any sense nor did he ‘redeem’ people as a whole. He defeated bad guys and rescued good guys, but never granted salvation from sin or died to save any followers as Jesus gave up his life to save the world. During the few end years of their lives, Jesus and Hercules were made to suffer a great deal. Jesus had to live being ridiculed and shamed where as Hercules lived in exile away from everyone as he spent twelve years doing the twelve labour he brought on himself to make up for the remorse he felt for brutally murdering his family. Ultimately Jesus and Hercules both met with violent deaths, Jesus died on the cross out of own free will for the love of his people, even though he did not voluntarily decide to die on a cross. Hercules on the other hand voluntarily decided to died on a pyre of fire as stories mention he wanted to get rid of the body that was responsible with the killing of his family.

Nowadays, Food Has Become Easier to Prepare Essay

Nowadays, Food Has Become Easier to Prepare. Has This Change Improved the Way People Live? Use Specific Reasons and Examples to Support Your Answer. By annicat Man, through the ages, has undergone many changes, from a period when he hunted for his food to the present era when man is dependent on preprocessed foods. During this period not only has man changed his mode of eating but his whole lifestyle as well. In pursuit of more in this competitive world, man no longer has time as he once had. He is caught in a race against the clock. A person who finishes more n lesser time is considered more efficient. This pressure to do more in less time has affected his eating habits as well and, as a result, man no longer has time to cook food. Early man’s only objective was to seek food to sustain him and his family. Nowadays finding food has taken a back seat to other priorities, such as career and education. Food is no longer of that importance. This is not an encouraging trend. People are too dependent on preprocessed or precooked food, which no longer has the freshness it once had. Such foods loose their mineral and vitamin content and re not as healthy as fresh food. That is why the number of diseases is also rising. People have also shifted to high calorie content food like French fries, pizzas, and ice cream, etc. , which is causing obesity, fatigue, etc. As man is becoming busy and too involved in his busy schedule, he has no time even to take care of his own personal needs. Furthermore, cooking is an art which is dying out. People once enjoyed cooking . It was a means of eliminating stress and tension. People were once able to relax during this time and reflect on their lives. People may tend to argue that by sing precooked and preprocessed food they are efficiently using time and can use this precious time saved for other purposes. But is it really worth it? This is a question whose answer can invite much speculation about whether by saving this little time we are inviting lots of other problems, which could easily be avoided. It is actually making our lives not simpler but more complicated. We have lost many of the simpler things in our lives, like the simple acts of selecting our evening meal, preparing it, and enjoying it with our loved ones, and we are worse off for it.

Lesson 7 discussion & - Assignment Example Devendra Banharts song touch upon his own reflections of the past, including the themes of social inequality. Willy Masons lyrics, just as that of Bob Dylan, are often focused on issues of tensions between social classes, poverty and existential problems, such as loneliness and senselessness of the modern way of life of an ordinary man. Beth Orton reminds me of Joan Baez with both her style of singing and subjects that her lyrics is focused on. She often sings of love and failed relationships between a man and a woman. I do not agree with Pete Seegers statement according to which folk magazines have to print the best rap songs. Although, the origins of rap root to American hip hop, which, in turn, is in incorporates some distinct features of traditional music of African American people. At first glance rap and hip hop have nothing to do with folk at all. In fact, these are different musical styles and genres. Unlike folk, rap is more of spoken word poetry with a monotonous rhythmic music on the background, where lyrics lie at the heart of every song and the role of music itself is neglected, though there are certain criteria to it among rap artists. Rap culture was initially widely spread in urban areas among African Americans, although today the situation has changed and the genre found its audience among other social and racial groups. Folk, to the contrary, rooted from suburban and countryside areas populated by white communities. On the other hand, comparing rap and folk Pete Seeger believed that there are more similarities in these two genres than differences. In fact, the way lyrics plays a the most important role in each and every rap song, touching upon social and existential issues, has a strong resemblance with the style and spirit of folk music, not to mention the historical implications of the development of rap genre. In spite of similar subjects that both rap and folk tend to

John Stuart Mill's principle of liberty Essay Example | Topics and Well Written Essays - 1750 words

John Stuart Mill's principle of liberty - Essay Example I prefer this definition of public policy because it establishes a direct connection between expectations of a society and the effectiveness of their embodiment by governments. With such observations in mind, let us try to find out to what extent, if at all, John Stuart Mill's principle of liberty is a workable and attractive basis for public policy in light of real-life challenges. ... ills principle to public policy, because in the latter case we may fail to exactly identify aspects of the principle that cause difficulties in its practical implementation as a basis for public policy. Besides, the fact Mill himself differentiated between the spheres of application of the principle of liberty in positive (freedom for personal development) and negative (knowledge that our freedom from harmful interference of others is protected) ways suggests that for him, as a utilitarian, this differentiation was needed in order to provide a practically applicable frame for his moral philosophy. Indeed, while for Mill the maximisation of happiness serves as the moral end, he realises that the task of distribution of limited amount of goods that can promote happiness requires the establishment of strict social norms violation of which should be punished for the common benefit. The first part of the Millian principle of liberty, which declares that a person has the right to do whatever he or she wants and be free from the interference from other people, stems from Mills principle of utility "grounded on the permanent interest of man as a progressive being".1 By this Mill implies that the choice of forms of governance should be based on their capacity to promote development of faculties of each individual, which would generally increase moral freedom, responsibility, and rationality among people, thus leading to more happiness. This aim is justified by the fact that free personal development is an end for each individual, and at the same time is a proper way for the whole society to thrive.1 So, it is after all the utility that dictates the best forms of social life.2 Therefore, with the personal development being the basic value, Mill states that liberty, insofar as it

Medieval Philosophy Essay Example | Topics and Well Written Essays - 1250 words

Medieval Philosophy - Essay Example In his illustrious Proslogion, Anselm longs for seeing the holy face of the Lord, which is, according to the Abrahamic mythology, impossible to do in this life on the earth. Consequently, idea about God can only be conceived and imagined, instead of seeing the countenance of the Lord. The theologian further expands his notion by stating the very fact that though the concept of God is much greater than human power to conceive, it does not put His existence in doubt altogether. Moreover, since God cannot be seen, but can be understood and imagined, it is somewhat a vehemently difficult thing to believe in someone unseen because of the deficient mental and physical faculties attributed to the human beings at large. Somehow, the fool would, according to Anselm, take the concept of God as an illusory matter in nature, which could only be supposed because of the characteristic of His concept, existing in the minds of the people only rather maintaining any reality in its scope. Since God has been in the fool’s understanding since long, but having no clear picture and image related to Him, the fool can understand His concept in the same manner as he conceives about the unreal objects that have no real existence in the world. Thus, having belief in the (Supreme) Being, unable to be conceived, is hard nut to crack for the fool.

FISH TRANSPORT DESIGN Assignment Example | Topics and Well Written Essays - 2500 words

FISH TRANSPORT DESIGN - Assignment Example This investigation is aimed at delineating criteria to transport fish followed by three concept level models. These models will be evaluated against the delineated criteria and the most suitable model will be chosen to transport fish over long distances. The business viability of the chosen model will be evaluated in terms of investment and operational costs to help fish owners and transporters decide if they wish to install such a system. NUMBERS OF FISH AND TIME FOR TRANSPORT The current problem clearly states that fish will have to be transported in numbers between 5 and 200 and that the fish can stay on the road for up to 2 days. The most expensive fish in the lot is the Koi Carp. The Koi Carp is potentially a very sensitive fish and needs to be cared for excessively. For the purpose of this investigation, the baseline of water quality will be taken as that for the Koi Carp. If the water quality for the Koi Carp falls below certain constrained levels, then a major loss or failure will be assumed. Constraint 1 maximum transportation time will be 2 days (48 hours) As mentioned before, the baseline will be taken for Koi Carp. Thus aeration constraints will be developed along the lines for the Koi Carp. The density of Koi Carps should be kept at 80 cm length of fish for every 1 m3 volume. (Koi Carps, 2009) The average size of the Koi Carp is between 24 and 36 inches. If these values are averaged, the size of an average Koi Carp comes out to be 30 inches (76.2 cm). (Davis, 2011) Constraint 2 ? fish density based on average size 76.2 cm Water Quality The largest problem in maintaining healthy fish is the dissolved oxygen level. Any variations in the oxygen level can spell disaster for fish especially if the oxygen levels are not replenished after half an hour to acceptable levels. (FAO, 2011) Any and all factors that affect dissolved oxygen levels in water must be considered and dealt with accordingly. Generally the aeration system is constrained by: efficiency of the aeration system; transport duration; temperature of water; fish size; fish speci es. It is essential that the water used to house fish is kept clear. Any turbidity should be avoided and filters should be installed in the system to remove any particulate matter. Constraint 3 ? turbidity clarity Moreover, the pH level must be checked regularly to ensure that it keeps around 7. The acceptable pH levels for housing fish are 6 to 8.5. Constraint 4 ? pH level average at 7 Water temperature has a direct bearing on the amount of oxygen dissolved in water. Oxygen solubility in water decreases exponentially as the temperature of water increases. Therefore, if the water temperature rises significantly as the fish are being transported, the oxygen levels in water will suffer significantly. (Engineering Toolbox, 2011a) The variations of oxygen levels with water temperature are graphed in Appendix A. Constraint 5 ? water temperature should not vary significantly Moreover, the oxygen content of the water needs to be checked regularly to ensure that it does not fall below the d esignated threshold of 5 mg / litre. The variation in oxygen levels is between 8 and 9 mg / litre. Constraint 6 ? oxygen levels in water averaged at 5 mg / litre Moreover, the water quality should be maintained within the constraints listed above and no value should be allowed
