After the woman had settle down and he asked her what it was the hair that she wanted,she showed him coupled passages of hair styles she had ripped from magzines,and he seedmed to appreciate her pendant for trying new things. he was warren beatty in shampoo,holding his hair dryer with that certain movie-star swagger. And because of stylist appearance so the woman put her trust on the stylist hand,and fallin sleep. About thirty minutes passed,by the end of the qpointment,then the woman opened her eyes and looked into the mirro,she was astonished that the stylist had ruined her hair,and it looked totally bad,the woman then screamed†My hair! You ruined my hair! †The stylist looked scared and the stylist said†I’m so sorry,I apologize for all my mistakes,I accidently took a wrong bottle of dye and ruined your hair,and I could help you to dye your hair again if you want. †Ã¢â‚¬ yes! yes! The woman yelled out. Everyone was laugh at her,and the sun ouside the hair salon shone more happily.

Ultrahigh Bypass Ratio Propulsion Systems Studied

celerate a large mass of air by a small amount than to accelerate a small mass of air by a large amount. In a turbofan jet engine, the airflow rate that bypasses the engine core divided by the airflow rate that travels through the core is called the bypass ratio. The bypass ratio, or BPR, is one of the key indicators of turbofan engine efficiency. The desire for better fuel efficiency has resulted in the evolution of commercial aircraft gas turbine engines from early turbojets (BPR=0), to low bypass ratio, first generation turbofans (BPR=1-2), to today's high bypass ratio turbofans (BPR=5-10).Now, ultrahigh bypass ratio (UHB) turbofans (BPR=10-20) are being designed for a next-generation, intracontinental commercial aircraft. This aircraft could enter service as early as 2020. The Intercenter Systems Analysis Team, consisting of systems engineers from Glenn and Langley Research Centers, conducted an analytical feasibility study of UHB turbofans for NASA's Fundamental Aeronautics Prog ram. With a little math, it can be shown that fuel efficiency increases along with BPR.The engine core, however, has a limited supply of power available to propel the bypass air stream, so it can be difficult to simply increase BPR arbitrarily. One path to UHB engines and better efficiency is to reduce the fan's pressure ratio, which lowers the fan's power requirement and allows higher BPRs. Our analysis team designed nine notional UHB propulsion systems for this new aircraft along a parametric design sweep of fan pressure ratio. Using advanced computational tools, these propulsion systems were ana

Unwritten Laws of Engineering and Laws of Personality Assignment - 5

Unwritten Laws of Engineering and Laws of Personality - Assignment Example Skakoon asserts that these laws are like the norms of a society, which cannot be violated through impunity on a frequent basis.There are three major dimensions of unwritten laws of engineering that need to be taken into consideration. The first essence of unwritten engineering law that needs to be given consideration by engineers is: Lessons that need to be learned by beginners in the engineering field; these lessons cover three major issues, which are:   - Issues related to their work: Beginners in the engineering field are required to give their first duty, no matter how minor they may appear, a high sense of commitments and professionalism.   - Issues ascribed to their supervisors: According to Skakoon 2001, engineering supervisors have the right to know the level of progress of activities in their departments. In this regard, beginners in the engineering field are required to ensure that their supervisors are kept up-to-date on issues affecting their duties (10).   - An interpersonal relationship between them and their colleagues as well as their supervisors: In addition, Skakoon asserts that beginners in the engineering field should endure that they maintain a good inter-personal relationship between their colleagues and other stakeholders. This can be achieved through proper communication techniques and keeping an information update.Another dimension of unwritten laws of engineering is the chiefly relationship with engineering managers. The article explicates three techniques that can be applied to achieve this, they include:  Ã‚   - Technique and Individual Behavior: According to Skakoon 2001, the need to know about what is going on by a manager in an engineering department is another unwritten law of engineering. This can be achieved through collaborations and facilitating a positive relationship between the manager and their subordinate staff (23).   - What managers owe their employees: Skakoon notes that engineering managers are the face of their organizations. In this regard, they are required to facilitate a positive representation of their subordinate staff.

Determinism, Compatiblism, and Libertarianism Research Paper

Determinism, Compatiblism, and Libertarianism - Research Paper Example I will divide my paper into four main parts. Part one will be devoted to an analysis of determinism. I shall use Paul Holbach’s version of this position. In contrast to part one, part two will tackle the libertarian position. Here I shall use Roderick Chisholm’s version. And part three will discuss the compatibilist view on free will. In doing so, I shall use A. J. Ayer’s version. Finally, I will show the main strengths and weaknesses of each. I will conclude my paper by giving an explanation on why I think compatibilism is the most feasible and practical among all three. Determinism: Everything Has A Cause Determinism is the view that rests on the assumption that everything has a cause. â€Å"All doctrines of determinism imply that given the past and the laws of nature at any given time, there is only one possible future. Whatever happens is therefore inevitable† (Kane 285). What does this imply? It simply implies that â€Å"we could not have chosen othe rwise† (Feinberg and Shafer-Landau 410). To illustrate this position further, I will explore Paul Holbach’s version of hard-determinism. Holbach says that we are not free. But how does he argue for this position? The main claim of determinism is that â€Å"whatever happens is determined by prior events† (Sie 2). Holbach is a hard determinist. ... But if my action is determined by past events, then I'm unable to act otherwise. Therefore, I don’t ever act freely. One can argue that it is not the case that I don’t act freely for I have my own motives, choices and I am not restrained. However, Holbach refutes this on the basis of â€Å"the complexity of human conduct and the illusion of free agency† (Holbach 463). Holbach argues, we only think we are free because we cannot explain the phenomena, but in principle, we can explain everything by explaining its causes (463). For instance, if I can explain my actions through the laws of nature then we have no use for free will anymore. So if we discover the cause of a given phenomena, then it nullifies freedom. Therefore, we are not free. Contrary to determinism is the libertarian position. I shall discuss Chisholm’s version of libertarianism next. Libertarianism: some of our actions are free Libertarianism argues that some events that happen are not determi ned by prior events. In defending freewill, Chisholm suggests: We must not say that every event involved in the act is caused by some other event; and we must not say that the act is something that is not caused at all. The possibility that remains, therefore, is this: We should say that at least one of the events that are involved in the act is caused, not by any other events, but by something else instead. And this something else can only be the agent—the man (440). Given Chisholm’s suggestion, I can say that my action-A is free if and only if I am the cause of A and that I could have done another action-B other than A. If determinism is true, I could not have done B. But I could have done B because I am the cause of my actions. My decision to do A caused me to perform A,

The Source Debate and the Similarities of Albovine and The Witch Thesis Proposal

The Source Debate and the Similarities of Albovine and The Witch - Thesis Proposal Example The Source Debate and the Similarities of Albovine and The Witch Controversy surrounds where a similar instance can be found in the beginning act of The Witch by Thomas Middleton: at a remarkable feast arranged for the marriage of Isabella and Antonio, the Duke passes around a skull fashioned as a goblet among the party attendees and makes them drink from it. As it happens, the skull belonged to the slain father of the Duchess, who is also present at the dinner and is expected to drink from it. This basic similarity between the two plays is the premise of my suggested thesis. In an article studying the true source of Albovine, Killis Campbell asserts that The Witch was not published until 1778 by the famous Shakespearean editor Isaac Reed; however, it is purported to have been written in the early 17th century by Middleton, in around 1615-1616. Albovine was registered in 1629 (Campbell) leading to clear possibility that Davenant had been aware of The Witch before Albovine was conceived. Further proof of his knowledge can be taken from the fact that he used the Witch in his rendition of Macbeth. Niccolo Machiavelli’s The History of Florence is also credited by some historians as being the source of these plays, including another Irish play called The Revengeful Queen by William Phillips; however, Phillips’ work seems to be based more on Machiavelli and both Albovine and The Revengeful Queen bear resemblance to the Witch, making Davenant’s work open to the charge of plagiarism.
