Main Idea Of The Road Not Taken - Free Essay Example

The Road Not Taken, written by Robert Frost, uses an extended metaphor of a walking path to emphasize how a choice he makes at any moment could have a significant influence on his future. Frost begins the poem by talking about the diverging roads he stumbled upon in the woods. He realizes he is only one person and can only take one path, so he examines them both in an attempt to make the best decision. The decision was not easy for him as he states, long I stood before he made the choice (3). To the best of his ability he studies both paths, but he is not able to see much due the paths curving and being enveloped with trees. Frost implies that he would like to obtain more information about each path by saying, And looked down one as far as I could, but nature prevented him from doing so (4). In the second stanza, Frost examines both paths in depth; he notices that the second path is more attractive. He concludes that no one has taken it lately because it was grassy and wanted wear (8). He seems to be very indecisive though, declaring that the second path is just as pleasant as the first. The speaker seems to be searching for a logical reason to travel down one path over the other, but the reason is unobtainable. Frost continues to search for a logical reason to choose a certain path in stanza three. He continues to analyze the paths in hopes of finding something to make his decision simpler, but both paths are almost identical. He observes that neither path has been traveled lately because the leaves have not been walked on. It starts to become apparent to Frost that he is not going to find a clear reason to choose a certain path. The speaker knows he needs to make a decision, so he decides to take the second path. He tells himself that he will come back to the forest and take the first path another day. Frost uses an exclamation mark after line 13 to express his excitement of finally making a decision and being able to walk down both paths eventually. His excitement quickly weakens when reality sets in. He acknowledges that one road can lead to another and that he may end up very far from where he started. He doubts he should ever come back, as much as he wishes he could. The tone in the last stanza, stanza four, changes drastically. The speaker jumps forward in time to reflect on his decision. He says he will be telling this story somewhere ages and ages hence, which implies that the story is important to him (17). He then proceeds to repeat the first line of the poem, two roads diverged in a yellow wood, with a few modifications; he removes the word yellow and inserts the words and I (1). By doing this the speaker has emphasized that important part of the poem, the idea of choosing between two different paths. The speaker sums up his story in the last two lines of the poem. Frost states that he took the one less traveled by; even though he said the paths were almost equal, he believes that the one he chose was a little less worn (19). He believes that taking the path that was less worn than the other made all the difference in his life (20).

The Importance Of Architecture In Ancient Greek Architecture

Classical Architecture spans over a vast amount of time, although the main period Classical Architecture is said to have started is during the Archaic Period in Ancient Greece. Greece during these times wasn’t a unified nation, but many independently governed city states. They all varied in power, forces, defenses, economy, etc. Even though these city states remained separated throughout Ancient Greece there was a unifying force. Greek mythology was an ideology that had been supported all throughout Ancient Greece. A polytheistic religion that had various gods, as well as many forms of the same god specific to certain areas. The King of the Gods was Zeus, and the next two most influential Gods were Hera, and Athena.

The Ionic also differed because it had a base and a sculpted frieze, and was als o topped with a cornice and a pediment. What visually set the Ionic order apart from the other orders although was the volutes on the capitals. Lastly, the last order invented by the Greeks was the Corinthian order. This column was the slenderest of all the columns and the tallest. It was built to the proportions of a young women and came out of the Greek Islands. The top just like the others housed a pediment, but the entablature only had dentils. What really sets the Corinthian order apart although is the sculpted capital in the shape of acanthus leaves. This order was the most ornate and wasn’t built until Hellenistic times in Ancient Greece. Nevertheless, the Greek orders were intended for the religious temples that made the Greeks well known. Many Greek Temples shared very common floor plans, a central cella housing a shrine to the corresponding god the temple is for. As well as periptural columns, that wrapped around the exterior of the building.

Investment In Information System Samples †MyAssignmenthelp.com

Question: Discuss about the Investment In Information System. Answer: Introduction In recent times, the conditions for business are changing very quickly due to advancement in information and technology system. This report is telling the procedure of choosing ERP/AIS to formulate the decision of investment in information system. To understand it more clearly the report focuses on various points like process and requirement of business, requirement of system, and choosing the correct retailer. The company, which is taken for this assignment, is Arnotts biscuits. The company deals in biscuits and snacks food and it was founded in 1865. The company is one of the leading manufacturer of biscuits and second largest provider of snack food. Business processes Business process for the organizations is set of linked task, which are interrelated to each other and achieve the objective of the organization by delivering the product or service to the consumer. The systematic process of business will improve the efficiency and performance of business and systematic process means less probability of error. ERP helps the organization in organizing a systematic business process. There are five production lines at the Huntingwood factory that manufactures the Arnotts biscuits: Line 1 for the production of Jatz and Sao crackers biscuits. Line 2 comes in use for the other crackers biscuits and for the making of crisp breads. Line 3 produces plain and semi sweets biscuits like Scotch Finger and Milk Arrowroot. Line 4 comes in use to shape the varieties of biscuits. Line 5 produces only chocolate biscuits like Tim Tams and Mint Slice (Oxford, 2014). With the help of ERP (enterprise resource planning), Company can estimate that in what quantity raw material will be required for the production of biscuits on daily basis. Enterprise resource planning explains itself, that it will help the company in planning their resources. It is software, which help the company in improving their performance by reducing the wastage materials. It provides almost correct estimation of required raw material. In addition ERP, also assist the company by providing correct planning of available resources and mentions the production of units in the available resources (Leon, 2014). It is a cost effective method, which reduces the extra expenses on production of the company. Requirements of business Business requirements are related to the particular needs of the management, which assist the company in achieving their objectives and goals in an effectual way. Therefore, the requirement of the business must be clearly specify to the management by that management will fulfill all the requirements for the various departments because lack of any required demand can affect the production of the business. The requirement is not limited to internal factors like finance or availability of raw material, requirement can be related to external sources also as promotion activities, transportation etc. all the demands which help in improving the efficiency of workers and improve the performance of business that can be a requirement for the business (McFarlane, 2012). There can be several requirements for Arnotts biscuit to improve their performance that are as follows: Although company is successful in Australia and even in New Zealand, USA, Japan. However, it is high time where company needs to expand in big markets like China. The company always keeps on working on their biscuit taste and on new flavor because their business is totally depends on the taste and quality of their item. Due to high competition in the market, company needs to expand their factory area by that production of the units will be increased; this will result in constant supply of the product in the market. Company needs to work on their advertising strategies because in fast moving world, it is hard for everyone to remember the advertisement and then purchase the item. Therefore, company needs to be more creative and effective with their advertisement by that people will easily recall the brand (Simatos, et. al., 2012). Requirements of System Requirement of system are different from the requirement of business. The requirements of system are explained in a means of explaining advanced plan to convey business requirement. ERP and AIS are the softwares, which helps the company to manage all their resources whether it is internal or external. AIS (Accounting information software) assists the company in maintaining the record of every financial related activities like resources of finance, salaries, details of assets, cash in hand, etc. Whereas, the work of ERP is to plan that how company can use every single resources, by that wastage can be minimized and production can be maximized. Every business requires a correct system, which helps the company in smooth running of operations (Slack, 2015). The requirement of system can be anything; by that, organization will not face any difficulty in achieving their goals and objectives. There are various system requirements, which are as follows below: Server hardware: for successfully installation of the ERP software company needs to upgrade their system according to the demand of the software because these software does not work on outdated system. Arnotts biscuit was created in 1865, and the company knows the affect of up gradation because they have upgrade with new flavor and taste in their biscuit that is why they are still running in the market. Likewise, company needs new system with upgraded features, which help the system to run effectively. High accounting features: When company is big in size, then it is mandatory for that company to have high level accounting softwares in their software, which are able to solve any problem and records, and keeps the data safe. Arnotts biscuit is very big company, which supplies their product in various countries like New Zealand, USA, and Japan (Galliers, et. al., 2014). Therefore, company must have the advanced accounting softwares, which loaded with all the features and makes the work easy for the accounting department because there will be high amount transaction and there is no chance of any mistake in recording that. For that reason, these softwares assist the company. Software and vendor selection It is very important for the organization to have correct software in their systems because all the information related to the company is stored in the systems. Now, the work of every organization is depending on the systems. Effective and advanced systems have made the work easy of the organizations. There are various software, which made the work easy for the companies, but most popularly software, which every company has, are ERP (Enterprise resource planning) and AIS (Accounting information system). ERP helps the organization by providing the correct planning and utilization of resources, whereas AIS software is the accounting softwares, which helps in calculating all the financial use. Like use of finance, sources of finance, storing the expenses of company and calculating the salary of the employees can be done with the help of AIS. Although there are, various accounting softwares are there in the market but most popular software among the organizations is MYOB (Romney, et. al. , 2012). Along with the correct software company must select the correct vendors which sale their product in the market. Arnotts is very old company and still running in the market due to they have correct vendors in their hand. However, to expand their business company needs to increase their vendors by that sales and profit of the organization will increase. However, there are many vendors in the market but finding the correct and viable vendor is necessary for the company because ultimately vendor is selling the product of the company and if vendor is involve in some legal issue then it will hamper the sale of the product from the side of that vendor. Therefore, it is very much essential to choose correct software and correct vendor (Romney, et. al., 2012). Ways by which companies can develop business effectiveness There are several ways, which helps the company to improve their business efficiency. These methods are as follows: Communication: Communication plays an important role in achieving their goals and objectives. Proper communication is very much essential at the workplace and for the Arnotts biscuit, it is mandatory to communicate each thing among the employees because company makes biscuit and lack of communication can hamper the production or taste. In todays competitive market communication is not only required at the workplace but also company should communicate with their customers and must take feedback about the products and try to know what new their customer wants in the product like design, taste etc (Becker, et. al., 2013). Motivation seminars: Company must conduct motivation seminars for the employees by which employees get motivated and increase their working efficiency. Along with this company can conduct role-play sessions by which employees get opportunity to show their ability. Periodic review: It is mandatory for the organization to review the performance of the employees at regular intervals. This will help the company to review the performance of every employee. This review session is very much beneficial for both company and employee because if there is any employee who is not meeting up the target or facing any problem at workplace this session will provide opportunity to talk with their superior and overcome the problem. Easy processes: It is essential for the organizations to focus on the easy processes of working at the workplace, by that employee can work easily and does not feel any pressure. The planning and process must be easily understandable to all the employees by that they can work with more efficiency and helps in increasing the company profit (Becker, et. al., 2013). Monetary benefit: Company should give monetary benefits to the employees, who do their work with effectiveness and do fewer mistakes. This will motivate the other employees to work with more efficiency. If every employee start working with more efficiency and do fewer mistakes, that will increase the profit margin for the company because less mistakes means less expenses of the company. Level of efficiency of the technology implementation In the modern era of business, it is the significant need of every organization to install new and advanced technologies at the work place, which will improve the work efficiency of employees and business. For small-scale organizations, it is necessary to upgrade their machinery to sustain in the market. Technology not only saves times but also improves the efficiency of the work and affect the quality of the product. Technology plays an important role in the profit of the organization because due to modern technology the production of units increases by that there is enough supply of the product in the market that will result in high sales, which will increase the profit for the company (Wheelen, et. al., 2011). Arnotts company deals in biscuit and snack food. Company produces thousands of biscuit daily with the help of technology. Technology like oven in which biscuits baked and robots, which give shape to the biscuits. With the help of technology or heavy machines has made the production work easy for the Arnotts biscuit. The only problem occurs while working on technology is proper knowledge of the machine. Company should conduct a short training session for all the employees by which employees can learn how machine will be operate. It is necessary for the organizations because every organization wants to increase the production of the units and that can only be possible with the help of technology (Wheelen, et. al., 2011). Technology not only helps in increasing the production or makes work easy but also creates an automated work environment at the workplace. Potential security risks and data breaches There are several types of security risks and data breaches in the company. In this modern world, the security risk has increased by various reasons. Now, Companies are investing huge amount of money to protect their data. These security risks are as follows: Theft: It is one of the common risks, which every organization face. Theft of any material or data can damage the status of the company. Like, if any employee of Arnotts biscuit breaks the trust of company, and gives the confidential information to the competitors then it will put negative impact on the business of the company. Electric item: This security breach arises due to carelessness of the responsible person. This reason has emerged in the recent times very often that person forgets their belongings like laptop, phone and pen drive in office, airports, restaurants or any other place by which the chances of leakage of data increased, which will not good for the company (Chakraborty, et. al., 2011). Hacking: In the modern world, where everyone is online. Many businesses run online and sell their product online. The major risks with these businesses are hacking risk. Hackers can hack the official site of the company and can put wrong details on the site, which will be read by the consumers or any other user. Wrong details of the company or product will not only damage the image of the company but also shut down the company. In this advanced technological world, it is easy for the hacker to hack the site, which is why companies are spending huge amount of money to protect their systems from hackers (Chakraborty, et. al., 2011). Guidelines to mitigate the risks It is very much important for the companies to protect their companys data and other confidential information. To protect these high-level information or systems, companies must make a team of skilled and technological friendly people who are goods at technology and are able to adjust in any situation. Along with this company must install highly advanced anti hacking software in the system, which will help the company by stooping hackers in accessing company system. These software not only stops hackers but also save the data in any conditions like if system damages then these softwares has back up of data by that company can again access their data by following some steps. Conclusion The report concludes that Arnotts biscuit company is making biscuit from 1865. The company is the largest manufacturer of various varieties of biscuits in Australia and second largest supplier of snack food. The company is the subsidiary company of the United States Campbell Soup Company. The report focuses on the business process of the company where how they make biscuit and their production lines are described in brief. Along with this, this report mentions the requirement of business as well system. Various requirements of both these are mention above. To be successful in the market it is essential to choose correct vendor and softwares and Arnotts biscuits are very much conscious about this. In addition, this report explains the reason by which company can improve their efficiency (Slack, 2015). The report also concludes the various security risks and company is spending god amount of money to protect their systems and data. References Becker, J., Kugeler, M., and Rosemann, M.

Karma And Samsara Essays (1277 words) - Shabda, Reincarnation

Karma And Samsara The belief in Karma and Samsara form the basis for the Hindu's religious worldview. It has been central to Hinduism for thousands of years, and as a result forms a major part in the philosophical thinking of many Hindu's today. The ideas of Karma and Samsara are evident in almost all of the great Hindu scriptures, being touched on in the Veda's, but first properly introduced in the Upanishads. When the idea of Samsara was first introduced it led to a quest for liberation through the practice of austerity or meditation or both. To be released form this life the Hindu's needed to wipe out the effects of their past actions or Karma. It is this set of beliefs that formed the background of many of Hindu's religious movements and beliefs. Karma is the belief according to which a person's future life is determined by past and present actions. Every action, bodily, intellectual or ethical, good or bad, big or small will have its effect. Nothing other than the effects of earlier actions has determined the present state of affairs and nothing other than the present actions will determine the future circumstances. The law of Karma allows no room for chance or divine intervention as everything is inevitably determined by it. The Brhardaranyaka Upanisad simply sates "By good actions one becomes good, by bad actions one becomes bad"(4.4.5) (Koller 1982: 59). Intertwined with belief in Karma is the idea of Samsara, which is the cycle of repeated births and deaths that subjects an individual not merely to one death but to innumerable deaths (Koller 1982:9). Hindu's believe that as a person dies the Atman (the unconscious, immaterial part of a human) carries the results of their good and bad actions (Karma) into their next existence. This previous Karma will determine what sort of position a Hindu will occupy in their new existence, for example, if a person in a low caste has been very good in their past existence they will be born into a higher caste in their next life. The ideas of Karma and Samsara have justified the unequal Caste system, which has been an integral part of Indian society for hundreds of years. At the time of the Rig Veda (the earliest Hindu scriptures around 1000 B.C.E) (Smart 1989: 60) the key concepts of Karma and Samsara had not actually been stated. However, it does mention that a person's conduct in this world determines his life after death. The brahmins (the religious leaders) stressed the importance of the sacred act of sacrificing which was supposed to have a bearing on man's fate in the next world, and consequently the Satapatha Brahmana 11.1.8,6, states that "the Sacrifice becomes the self of the sacrificer in the next world"(Stutley 1985: 23). So, even at this early stage of Hinduism, the idea of Karma played an important role in the Hindu's worldview. It was not until the Upanishads (the principal ones dating from 800-400B.C.E) (Smart 1989:49) that we first meet with the doctrines of Karma and Samsara. The Upanishads are concerned essentially with the meaning of the sacrificial rites, and come to the conclusion that knowledge in the ?true reality' is the key rather than expertise in rituals like the Rig Veda's were. In the process they introduce profound metaphysical and religious ideas, such as Karma and Samsara. The Chandogya Upanisad sums up the ideas of Karma and Samsara "those who are of pleasant conduct here the prospect is indeed that they will enter a pleasant womb, either the womb of a Kshatriya or the womb of a Vaisya (high Indian Castes). But those who are of a striking conduct here the prospect is indeed, that, they will enter the womb of a dog, or the womb of a swine, or the womb of an outcast"(Lipner 1994: 45). The central concept in the Upanishads is that of Brahman. Brahman is the highest truth, the eternal being on which all other beings depend on. Brahman is the same as the atman, in other words, that ultimate being out there, is the same as that eternal something within you. The goal for many Hindus became at this time to gain Moksha (release from Samsara) which meant a person's atman would be released from the cycle of rebirth and therefore become one with the ultimate reality, Brahman, like a drop of water into an ocean. To understand the Hindus preoccupation with breaking the cycle of Samsara and gaining Moksha one must understand the Hindu's view of time and space.

Amplitude and period relationship Essay Example

Amplitude and period relationship Essay Example Amplitude and period relationship Paper Amplitude and period relationship Paper Oscillation is a motion, which repeats itself. A simple harmonic motion is when object moves back and fourth within a stable equilibrium position. In a perfect situation, where friction plays no part the ball will continue oscillating continuously. However in real life this is not possible, instead objects face damping due to friction. Any system which carrys a harmonic motion is known as an oscillator. Simple examples are a mass on the end of a vertical spring, a pendulum, or a trolley tethered between two springs. The amplitude of an oscillation is the maximum displacement of the system from the rest position. Hypothesis: In this experiment I will be changing the position from where I will be dropping the ball into the bowl from thus the amplitude will be changing. In my view the higher the amplitude would result in longer time for the ball to return to its original point of release at the maximum amplitude. This would result in a long period of time. For the movement of the ball in the bowl is caused by the inward push exerted by the surface of the bowl. Therefore by increasing the amplitude the time period will increase. Galileo was the first person that studied about pendulums and said about the property of them that the period is not dependent of the amplitude of the swing. But later on Christiaan Huygens found that if an object is going down a curve due to gravity and if period is independent of the amplitude then it should move through a cycloid curve instead of a circular one like in a pendulum. It supported the observation of Marin Mersenne who said that the period of a pendulum changes with its amplitude and Galileos observation was only correct for small amplitudes. In case of larger amplitudes, the period will increase with amplitude. Discussion : I have recorded four observations for each of the positions I dropped the ball from. This is because I wanted to make my experiment more accurate thus I decided to time the movement of the ball for four times for different amplitudes. Now for my next table, which I will use for the graph, I have to calculate the average of the 4 results for each amplitude but before that I divided each time recorded by the number of oscillations it made to find the time made by the ball for one oscillation. Here in this graph we can see that the period hardly changed so it means that the amplitude affected the period very minutely. We can notice that as the points dont have any link in between them. If we see the first 3 readings for 5,10,15 cm amplitudes, our hypothesis seems to be right as by increasing the amplitude the time period is increasing accordingly but if we notice the next 2 readings for 20,25cm amplitude, this rule does not apply . Conclusion: I find that the period did not increase because when we increase the amplitude it obviously means the tennis ball will be dropped from a higher position so thus it will gain more speed while falling down , therefore if the amplitude increases the speed also increases causing the tennisball to take just as long to complete a cycle as in the case of smaller amplitude. I didnt considered the friction of air. The friction caused the tennis balls speed to slow down and led to a decrease in the length of the arc through which it passed. Like if we take an example in which drop a ball from an angle of about 60 degrees within a short number of cycles the tennis ball will not move beyond an angle of 20 degress because of the friction so it is not a continous movement. The air friction is caused when the object moving through the air and has to move air molecules aside. Also the surface parallel to the direction of the motion of the object generates friction because when the molecules of the air which collide with the surface and are thus pushed in a forward direction by the collision. Therefore, I can conclude that the period was independant of the amplitude because the periods in all five cases differ very little from eachother. Evaluation: I felt that this experiment was accurate up to and extent however there were many things which we could have changed in our methods of doing this experiment to make it more accurate such as when we held the mat in the form of an arc shaped it was difficult to keep it the same throughout when the tennis ball was rolling so we could change this by placing the mat between a chair and the wall which would the mat into place this would make it impossible for the mat to move and the size to change even slightly so this could have cause us to get even more accurate results. Also the speed applied when I was dropping the tennis ball couldnt be measured so we can try to be more accurate to not apply any force, so the force applied wont affect the results. In over all in my view this experiment was properly planned, as we were able to finish it in a sufficient amount of time. To make our results accurate we tried our best by recording the time period 4 times for each of the 5 different amplitudes and then taking out the average. There were also problems when I dropped the ball in the mat it basically wobbled and moved from one side to the other and didnt just follow the same path while moving so this might have caused some inaccuracy in the results. We could have improved this by not using a mat but something else like a bowl to roll the ball in where circumference would stay same during the whole experiment. Follow up experiment: Since in this experiment we looked at the link between the amplitude and period, after this we can take the initiative to look and compare between two other properties. So we can look at the influence of changing the mass on the period. We can try placing different weights in a small cylindrical tube and then rolling it. The amplitude will remain the controlled variable in this case.

The copernican revolution - Essay Example They made arguments against Copernicus’ writings, whether they were Protestant or Catholic, and overall agreed to condemn them in a religious manner. In addition, these leaders found that Copernicus’ writings disagreed with the ancient theories of Aristotle and Ptolemy, giving their objections not only a religious aspect but an alternative scientific explanation that was more consistent with their beliefs. They showed quotations from the Bible such as Psalm 93 that indicated that the earth was station, also claimed that the science behind Copernicus’ arguments was impossible regardless of the scriptural conflict. Cardinal Bellarmine’s letter comes after Galileo supported Copernicus’ writings. The Cardinal writes to the leader of the Carmelites, who attempted to reconcile the Copernican theories with Catholic scripture. The Cardinal pointed out that making this claim was bound to cause more controversy, and could be dangerous. He also insisted that e ven if some conflicts could be resolved, it would be most difficult to reconcile all scriptural passages with the science, and thus the science would have to be wrong. He warns against the heresy of misinterpreting scripture, and says that there still is no real scientific evidence behind Copernican theory.

Construction Technology, Services and Materials Assignment

Construction Technology, Services and Materials - Assignment Example Extrusion rates of twenty thousand bricks per hour are what modern brick manufacturers work with. Solid bricks used are of the size 215mm x 102.5mm x 65 mm and weighs 3 kg. But this varies from one region to the other. Harvesting of clay is by bulldozers, scrapers or mechanical shovels. Stockpiles are put to enable the blending of the various types of clay. The clay piles are fed to the primary crushers to reduce the size particle to 3mm or less (Kaushik, Rai & Jain, 2007). Conveyors carry the clay for secondary crushing in the pan mill whose base is perforated the crushed material to pass through (Lingling et al 2005). Clay particles fall between high-speed rollers for grinding. Wet clay is moulded into bricks. For this study the standard size of the manufactured brick is 215mm x 102.5mm x 65mm with a mass 3kg. This is according to the BS EN772 and the BS PAS 70 standard methods of testing. These methods ensure to control the weight, height and quality of the bricks which gives the overall strength. Bricks’ compressive strength varies according to the different qualities of clay material used and the firing method. Bricks made from white clay tend to be lighter and economical when firing. White bricks are fired at a temperature of about 12000C. Black or brown bricks are heavier and require a temperature of between 1500 to 20000C. Fired bricks are tested for strength before allowed on construction site. Compressive strengths of bricks range between 3.5MPa to over 50MPa (Demir 2008). The durability of the bricks cannot be fully determined by compressive strength. If this is done a false picture of may be painted leading to disaster. Clay products used in construction of structures to support heavy loads need thorough testing. One of the best method in the laboratory test of the bricks is to look at close tolerances and strength (Lingling et al
