History of Civil Engineering Essay Example for Free

History of Civil Engineering Essay Civil engineering involves the design, construction, and maintenance of works such as roads, bridges, and buildings. Its a science that includes a variety of disciplines including soils, structures, geology, and other fields. Thus the history of civil engineering is closely associated with the history of advancement in these sciences. In ancient history, most of the construction was carried out by artisans, and technical expertise was limited. Tasks were accomplished by the utilization of manual labor only, without the use of sophisticated machinery, since it did not exist. Therefore, civil engineering works could only be realized with the utilization of a large number of skilled workers over an extended period of time. * Prehistoric and Ancient Civil Engineering Structures It might be appropriate to assume that the science of civil engineering truly commenced between 4000 and 2000 BC in Egypt when transportation gained such importance that it led to the development of the wheel. According to the historians, the Pyramids were constructed in Egypt during 2800-2400 BC and may be considered as the first large structure construction ever. The Great Wall of China that was constructed around 200 BC is considered another achievement of ancient civil engineering. The Romans developed extensive structures in their empire, including aqueducts, bridges, and dams. A scientific approach to the physical sciences concerning civil engineering was implemented by Archimedes in the third century BC, by utilizing the Archimedes Principle concerning buoyancy and the Archimedes screw for raising water.

During the era of battles or operations, the engineers were engaged to assist the soldiers fighting in the battlefield by making catapults, towers, and other instruments used for fighting the enemy. However, during peace time, they were concerned mainly with the civil activities such as building fortifications for defense, making bridges, canals, etc. * Civil Engineering in the 18th 20th Century Until the recent era, there was no major difference between the terms civil engineering and architecture, and they were often used interchangeably. It was in the 18th century that the term civil engineering was firstly used independently from the term military engineering. The first private college in the United States that included Civil Engineering as a separate discipline was Norwich University established in the year 1819. Civil engineering societies were formed in United States and European countries during the 19th century, and similar institutions were established in other countries of the world during the 20th century. The American Society of Civil Engineers is the first national engineering society in the United States. In was founded in 1852 with members related to the civil engineering profession located globally. The number of universities in the world that include civil engineering as a discipline have increased tremendously during the 19th and the 20th centuries, indica ting the importance of this technology. * Modern Concepts In Civil Engineering Numerous technologies have assisted in the advancement of civil engineering in the modern world, including high-tech machinery, selection of materials, test equipment, and other sciences. However, the most prominent contributor in this field is considered to be computer-aided design (CAD) and computer-aided manufacture (CAM). Civil engineers use this technology to achieve an efficient system of construction, including manufacture, fabrication, and erection. Three-dimensional design software is an essential tool for the civil engineer that facilitates him in the efficient designing of bridges, tall buildings, and other huge complicated structures. * http://www.thecivilengg.com/History.php CIVIL ENGINEERING (CE) Overall Focus: â€Å"Public works†/infrastructure and buildings/structures.

The Porter Analysis Essay examples -- essays research papers fc

Introduction   Ã‚  Ã‚  Ã‚  Ã‚  To perform the Industry Analysis it is better to follow Michael Porter's five forces model. This analysis framework was created so that it helps managers in their task to analyze competitive forces to the company. (Hill & Jones 80) This model is only one of the models that can be used for this task but it is one of the more popular models. The five forces that we will have to look at for this model are (1) the risk of new and potential competitors; (2) the bargaining power of suppliers; (3) the threat of substitute products; (4) the bargaining power of buyers; and (5) the degree of rivalry among established companies within an industry. (Hill & Jones 80) Barriers to Entry   Ã‚  Ã‚  Ã‚  Ã‚  The first force in Porter's Five Forces Model is Entry Barriers. These factors are those that make it harder or easier for another company to enter into the industry. High barriers to entry will keep potential competitors out of the industry and low barriers to entry will give an opening for competitors to enter into the industry if the industry returns are high enough. (Hill & Jones 82) The fewer competitors in an industry the more the existing companies can take advantage of higher prices and better returns. One barrier to entry is brand loyalty. Brand loyalty is very important for the sales of IBM. When personal computers first came out you had to choose from IBM or Apple. Both computers were great machines but when IBM became a better-known computer the name was very recognizable. Today your choice in computers is much more extensive. Even though there are many more brands to choose from IBM is still a popular name. If not for it's own products it is for their platform it has. IBM compatible is a widely used term when talking about computers. Many people when looking for a new notebook computer will then think about the name first. You may think well if the other computers are compatible then why not just get something that is cheaper? This is an option but the other way of looking at it is the name brand will be a better product. A second barrier to entry is switching costs. When IBM and Apple were the only computer systems to choose from people had to make a choice. When you went to buy one system then you had to buy all the software that went along with that system. Ultimately, IBM became the mor... ...oking at industry analysis is that the Five Forces model looks at an industry as a whole instead of each individual company.

Does God cause bad things to happen to His children? Essay

As one goes through life, tragedy and misfortune seem inevitable. One may be afflicted by diseases, involved in an accident or one’s child could die. Some people may consider this as purely bad luck. Others yet may consider it as karma coming back to haunt them for their past wrongdoings and transgressions. Nevertheless, it is common for people to question if God is the force behind the bad things. The question then arises, does God indeed cause bad things to happen to his children, or is there some force behind it? As long as one has faith and belief in God, the question is inevitable at certain points in life. However, the question as to whether God really does cause bad things to happen to his people is openly debatable. On the one hand, believers and non-believers alike would like to think that God punishes us and causes bad things to happen. To this group of people, God is trying to teach His children a lesson in addition to bringing them back to glory. On the other hand, others are of the opinion that God causes bad things to happen to them just to get their attention or to get His point across. The Book of Romans, 8: 28 – And we know that all things work together for good to those who love God, to those who are the called according to His purpose, forms the basis of this argument (Nelson, 1982). Free will. It would be safe to argue that God does not in any way cause bad things to happen to his children. In John 3: 16, the Bible talks of the undying love that God has for his earthly children that he gave his only son to die so that they could be saved from eternal damnation (Nelson, 1982). Accordingly, God has accorded human beings with the necessary freedom to act as they wish on earth but has also provided the rules that are to guide their action. More over, the consequences for disobedience have clearly been stated. The Good Book, the Bible, contains the Ten Commandments that God’s children are to abide by. Flouting the rules results in tragedy and misfortune. When people misuse their freedom, they cause bad things to happen to them. Too much of anything is poisonous. Concomitantly, too much freedom is harmful. Out of free will or freedom, men commit murder and even genocide (McLarty, N. d. ). When people err and disobey his rules and commandments they are separated from God love. This is what is referred to as falling from grace in the Bible. Thus, the same freedom accorded us by God is the same freedom that separates men from the love of God and also causes bad things to happen. It is worth noting that faith does not in any way qualify as some kind of insurance policy. On the contrary, it can only be described as a mantle of assurance (Riverpower. org, 2008). Consequently, there is no way that God causes bad things to happen to his children because He has assured in His Holy Word that He will be with us no matter what we encounter or go through in this life. This is because He is considered to be an all caring all loving God. He hurts when His children hurt which then means that there is no way that God would then cause suffering, tragedy and death. However, one can then ask the question. Since God is all loving, all caring and does not want his people to suffer, how is it that he does not stop bad things from happening? This takes us back to the point that God has accorded his children with free will that they are to apply accordingly. One has the option to do good or evil, both of which have consequences. It is openly clear that God operates under certain rules. Unlike humans who openly flout the rules provided for them, God does indeed respect his own rules. He keeps his end of the bargain as long as his children keep theirs. He will rescue those who call out to him and ask for his help because he is all loving and caring (Riverpower. org, 2008). If God was the cause of both good and bad things happening to his children, it would be tantamount to control. This would then make nonsense of the freedom/free will he has given to His people. Again, control would only serve to make them like puppets. God does not in any way seem to supersede human free will to choose their best course of action and enjoy the benefits or suffer the consequences after ward. The first evidence that God does not override the free will/freedom he has accorded his children is in the Book of Genesis. In the Garden of Eden, He had provided Adam and Eve with the necessities plus he also put rules in place that they were to adhere to; not to eat from the tree at the centre of the Garden (Nelson, 1982). He then let them choose their own actions. Consequently, he decided not to interfere with Eve even when she chose to eat from the forbidden tree. Ultimately, God does not in any way cause bad things to happen to his children rather they bring it upon themselves.

Hypnosis And The Controversial Issue Of Hypnosis - 1404 Words

Self 1 In the twenty-first century our society has become sceptic on the controversial issue of hypnosis. Our society recognizes hypnosis as a foolish man holding a swinging stopwatch in front of people saying, When I snap my fingers, you will feel sleepy. Our society does not recognize hypnosis as a way of therapy or treatment. Hypnosis by definition is a trancelike state that resembles sleep but is induced by a person whose suggestions are readily accepted by the subject. The word hypnosis comes from the Greek word that means sleep. This leads to the assumption that the person being hypnotized is asleep throughout hypnosis. On the contrary, the person is always awake and conscious. The person under hypnosis is simply in a state of deep relaxation and heightened awareness. To do this, the hypnotist is talking to the subjects subconscious. The conscious mind does things automatically. When the sub-conscious mind would be telling the receiver No to doing what the conscious mind is relaying. When the hypnotist direct a suggestion to the receivers conscious it will do it. The mind will respond to the hypnotist suggestion. If a hypnotist would tell a person that is under hypnosis that they are eating an ice-cream, in theory, the receiver would feel the sensation of the cold in their mouth and taste the sweetness. Another example of a hypnotist power of your sub-conscious under hypnosis would be the suggestion of feeling scared, the receiver’s body w ould show signs ofShow MoreRelatedInformative Speech On Hypnosis804 Words   |  4 Pagesfriend, his brother, and me to a hypnosis show.
