Mind Blowing Engineering in My Eyes :Industrial Engineering


I believe that engineering is an interesting and innovative field to move forward I’m a curious person to know the inside of equipment which is seen in the day to day life. Therefore, I decided to be an engineer believing that I’m good in mathematics and science. However, I specially chose industrial engineering among many other engineering fields because it is a flexible carrier which I can work on different subject areas; it is predicted as a high demanding job now and in the future; I enjoy getting the knowledge how things work and how to make things function better.

First, industrial engineering is all about finding more productive, easier, safer and less expensive solutions to get a better outcome from a process. It can be applied to living beings, information, machinery, materials, or energy.  According to the “Introduction to Engineering class materials”, industrial engineers can work in manufacturing, banking, airport or transportation design, health care, distribution and logistics. It means that industrial engineering is a flexible profession which we can work on any area we want. For example, I always wanted to work with cars and planes, but I didn’t like spend my time with engines as mechanical engineers do. However, being an industrial engineer, I still can work with the designs of the vehicles.  Moreover, even I’m not going to be a doctor or nurse, I have opportunity involve in the health care field being an industrial engineer (engineers). Therefore, industrial engineering is the best choice for me because of its flexibility.

Second, industrial engineering is a highly demanding job in coming years. According to Bureau of Labor Statistics, they are expecting only a 6 percent increment in industrial engineers in the period of 2010-2020 which is a slower growth rate than all other professions. Moreover it says that employers are more attracted to industrial engineers because of their versatility and it is not categorized to an exact field like mechanical or computer science engineering. They also believe the demand for industrial engineers to increase by 14 percent. In addition, according to statistics, industrial engineers’ annual median wage was $ 76 100 in 2010 (Statistics, 2012). Thus, there is a less risk to find a job as an industrial engineer in the future.

Third, as a kid, I used to see and help my father when he was working with engines and making small cupboards with wood and he taught me to work with him. When I grow up, I decided to search and work on making new things which are productive and efficient for people.  I don’t like to spend the time with the engines or computers, but I like to read and think more and come up with ideas which can be turned into efficient products with the help of computers and other machinery. After reading many articles, talking to many people and researching, I decided industrial engineering is the best choice for my life path.

In conclusion, I selected engineering because it is a versatile industry which allows me to work in many fields; it has a high demand and a job with increasing opportunities; Personally, I like to spend time thinking and imagining about how things work which exact needs for being an industrial engineer. Therefore, I think that industrial engineering a great opportunity to make future a success.

The Philosophy of Engineering for the Burj Khalifa- The world’s tallest structure


I attended a special lecture by Lawrence C. Novak which is organized by the civil engineering department of the University of Texas Arlington. In the lecture, the guest speaker, Novak, spoke about the world's tallest building, " Burj Khalifa", which is built in Dubai.
Burj Khalifa
The faculty member of civil engineering introduced the speaker, Lawrence C. Novak, to the audience as the Director of Engineering Buildings of the Portland Cement Association. He has served as the lead structural engineer for the Burj Khalifa, the world’s tallest building while he was an Associate Partner with Skidmore, Owings & Merrill. Moreover, the faculty member introduced Novak as an impressive interactive demonstrator. Novak introduced himself and then continued the talk towards the world’s tallest buildings. Then he directed the conversation towards the Burj. He emphasized the structure, and wind engineering.

Novak used a chart to show where Burj stands when he lists the tallest buildings. It is a building which has a height of 2716.5 feet which is considered as the tallest building and the freestanding structure in the world. It is a multipurpose building consisting of residencies, cooperate suits, hotels, and recreation facilities with an observation deck on the level of 124.  The structure itself has an attractive floor design which a shape of “Y” has based on the flower hymenocallis. He said that it is a popular design in Islamic architecture.  This building is composed arranging three elements around the central core. The stability of the building depends on the three elements around the center.

Burj is a tall structure. Therefore, Novak said that the wind was a major problem to them because it swings when there is a wind. In addition to wind issue, there were more problems they had to overcome. One of them is pressure and temperature changes with the height and its effects of the building with the weather conditions in Dubai.

Embekke Dewalaya




Embekke Devalaya, which is located in Udu Nuwara, is a temple dedicated to the God of Katharagama. This shrine was built during the Gampola regime under the rule of Wicremabahu the 2nd. According to the historical documents and information, the temple was built by the Queen Hena Kanda Bisobandara with the help of a drummer named Rangama (Embekke Devalaya, 2010). The sanctuary is an out-standing work of art because of its eccentric woodcarvings without any usage of metal. UNESCO has recognized these intricate woodcarvings as the optimum products of wood to be found anywhere in the world.
These woodcarvings are unique and obscure which demonstrate the greatness and skillfulness of Sri Lankan architectural and engineering designs. This temple consists of three main sections. They are the sanctum or Garagaha, “the Dancing Hall or “Digge” and the Drummers’ Hall or “HevisiMandapaya”. The Drummers’ Hall is the mainly designed place among the sections (Embekke Devalaya, 2008). The specialty of this temple is that this is all made of wood, inclusive of the nails (Embekke Devalaya, 2010).
The Roof Design


The roof of the Drummers’ Hall was constructed using a unique structure where we would not see anywhere else in the world.  The rafters, all angled from above towards the arriving guests, were stabilized together and retained in position by a “Madol Kurupawa”, a gigantic catch pin which is distinctive. This pin holds twenty six beams which makes it a marvelous creation in our history (Punchihewa, 2007). This roof is also completely made of timber. This shows the skills of carpentry of ancient Sri Lankan artists.
Carvings
The carvings are done with unique designs The beams, rafters, doorways as well as doors also have been decorated with manifesting designs and patterns. The capital pillars were decorated with Sinhalese classical patterns of art such as hansaputtuwa or entwined swans and entwined rope designs. Moreover, the pillars were carved with elaborated designs such as mother breast feeding child, soldiers fighting on horse backs, female dancers, and wrestlers, women deriving from a vine, bird with a human body, amalgamation of elephant-bull designs and blend of elephant-lion design. The most outstanding feature of elephant-bull carving is that when one covers the bull side of the design with the palm, the actual shape of the elephant with drawn out trunk is visible. Likewise, when the figure of elephant covers from the palm, the bull figure emerges.  Amid the carvings, there are 126 series of decorations, 256 designs of liyawelor border patterns, 64 lotus designs in pekada and 30 decorative patterns on timber and roof (Punchihewa, 2007). According to historical data, most of these carvings are most probably the work of the primeval artisan Devendra Mulachari (Embekke Devalaya, 2008).
When I was schooling I have visited this temple. At the time, I enjoyed the carvings and the beauty of the sacred place, but when I was doing this project I was able to know the true significance of the temple. I was fascinated to know about the amazing, unique design and the technique that was used to architect the roof of the drummer hall. It is a marvelous and eye catching design to last for a long time period. This made me think that how talented and skilled ancient architects were to create such marvels. Moreover, there was no fact of forced labor, for these creations show how involved and dedicated were the worker. According to my point of view, the excellent engineering and architecture of ancient kings and people were talented enough to create Sri Lanka a powerful, strong nation in ancient world.

Engineering an Empire – Greece



Greece, which was one of the greatest empires in the history, was a wonderful territory with their amazing engineering capability along with the creativity.  Greeks were rich in military power, wealth as well as knowledge. According to the documentary of “Engineering an Empire-Greece”, this empire was a great example for applications of the engineering and technological knowledge.
As a result of the geographical factors such as rocky mountains and the sea, ancient Greece was divided in to separate city states which were governed by the officials of each city states such as Sparta, Athens, Samos and Thebes. There were lots of ups and downs in this system.  On one hand, these city states were powerful in many aspects and they were more like separate countries. On the other hand, they struggled with each other except uniting as a country. Accordingly, Themistocles was one of the outstanding persons who aimed to defend for Persian armies who were excellent at battling on land. His engineering skills lead the Greece to have a strong naval power in Europe designing fleets which were more like war machines. A fleet was about 150 feet long sailed using 170 rowers in three levels in the ship. There were sixty-four, fifty-four and fifty-two rowers in first row, second row and third row, respectively. These missile shaped ships were powerful enough to defeat about two hundred Persian ships with forty Greek fleets giving a victory to Greece in the battle of Salamis.
Greeks were influenced their architectural engineering ability from their ancestors. According to the legends, Greeks were descended from Mycenaean. They have erected monumental tombs with perfectly assembled heavy stone bricks. The lion’s gate, which was seen at the entrance including two lions looking at the sky, was one of the most prominent examples for their talent in architecture. It is a monument which symbolizes the power of the Mycenae. Moreover, they have used an amazing structure to build the tombs.  These tombs were consisted of a massive door way and orderly arranged circular bricks shaping a roof in a conical outline. They were designed to enhance the ability to bear and to maintain the pressure inside and outside of the tomb in order to last them for a long time. Hence, we can still evidences of the superiority of the nation. Furthermore, Polycrates who was the dictator of another city state which was called Samos created a wonderful irrigation system to supply water to the city from a fountain across the mount Castro. Polycrates’ talented engineer designed a marvelous tunnel system,  in which all tunnels get together at the center of the mountain.  This invention was improved using mathematical theories including Pythagorean Theorem. In addition, Samos also had a powerful navy. Consequently, Athens had become a super power in the world at that time excelling military, technology, and in all other aspects.  The erected the monumental building to worship the Goddess Athena who is the God for wisdom.  The white marbled temple dedicated to the Goddess Athena was one of the instances to illustrate the architectural advancement of the nation and also the prominence of the Greeks. It’s the Parthenon temple which had used magnificent engineering techniques to erect the columns in white marbles. They had used simple cranes to transport weighty marbles. That’s how the engineers of the ancient Greece made monumental structures to last long.
In conclusion, Greeks were influenced by enormous and magnificent knowledge and talent in engineering in order to build a powerful nation. They had used their abilities in various manners to make their country proud. Moreover, their technological and architectural talent had even laid the foundation to the modern engineering in building strong structures and improving various systems that are necessary for modern man.

Critic for Jack Trammel's The Sleeping stones


“The Sleeping Stones” by Jack Trammell is a short story about a soldier’s wife who is hoping her husband’s return after the Civil War. Although this story contains a sad environment and sad tone with anticipation, it made me read it continuously with pleasure. There are many reasons that this story catches my attention.
One of the main reasons that the story did attract me was the elements of short story which have made the story more naturalistic. The theme of this story is an important because even if it is due to war or not, many women have to undergo number of hardships and desperations when they lost their husbands leaving kids along with their mothers. The setting of the story took place in a farming village in Kentucky which is the home town of the author. As I think, the fact that he was grown up in Kentucky has influenced him to set up the story in the certain location. He may have familiarity with springs which are colder for a normal spring in other areas. This makes the story even more natural when I read it. Even though the plot set up in America, this is not an unfamiliar plot for a Sri Lankan who experienced war for several years. I’ve seen many wives who have lost their husbands due to the war and struggled for the survival with her children likewise in the story. The characters of the story have well developed using different characteristics in the society.  Ella who was the protagonist reminds me one of my neighbors who loses her husband when Ella hugged her child when he asked, “Does this mean that Pa is going to be home?” Using dialogs for the character development is my favorite technique in this story because I feel tired when I read the stories which are too descriptive in a constant manner. According to my view, dialogs keep characters alive. The author has used similes appropriately to enhance the creativity of the story which sometimes made me laugh a little, “a somewhat overweight and short man, with hair that struck out wildly from one side of his head like a snake lashing out.” Moreover, the simple dictions, which can understand through the context, he had used helped me to read continuously without wondering what some words mean. The writer has used the familiar symbols in order to provide clues about the story. I love that way because those symbols make me argue with my own mind to guess what is going to happen in the story.
To sum up, the author, Jack Trammell has done a wonderful job writing this story which keeps me concentrated. It is an awesome story which has decorated with the elements such as plot, setting, theme, characters, symbolism and style. These accessories have enriched the quality of the short story “The Sleeping Stones” conquering the minds of readers.

Review for Jack Trammel's The sleeping stones


“The Sleeping Stone” by Jack Trammell is a first world short story which is written based on the period of the Civil War in United State of America.  In the story, Trammell tried to convey the effects of war in a wife’s perspective whose husband died during the war. Moreover, he implies wife’s strong desire to see her husband’ return.
The author
Jack Trammell is an American writer, researcher, and a professor who is born in Berea, Kentucky. According to the sources, he lives in a small village in Virginia with his wife and seven children. He has started his writing career when he was a teenager. So far he has written many poems, short stories, journal articles and novels vary from text books to award winning publications. Moreover, he has written regular military column for the Washington Times for several years. He has become a member of many associations related to literature work such as Poets & Writers association in New York, The Poetry Society of Virginia, and The Writer's Club of Virginia. “The Stepping Stones” is a short story of his “The Civil War Collection” along with “the thing you want,” “Spoon Boy,” “A Glimpse of Heaven,” and “Company G.”
Summary
This plot of this story intervened around Ellie whose husband, Horey, joint the army during the civil war. The story tells us how she deals with life hoping to see his husband returning after the war. However, she strengthens her mind to admit that her husband has died during the war and to live the rest of her life with her children.
Plot
The plot of this story arranged chronologically which begins in spring and ends in summer without changing the flow of the story. Moreover, the writer has used foreshadowing as plot devices. He has given clues using weather, “why was spring reluctant this year? Surely enduring such miserable, starving entitled them to decent planting weather.”
Exposition
In the exposition, we are introduced the main character who is Ellie and the hard life she spends. Furthermore, the exposition includes the setting the plot takes part which is spring.
““Spring is not meant to be cold.” This is what Ella thought as she bent over and picked up the sleeping stones she had placed outside several days ago. The way sun was shining made her feel as if the season was being cheated. She moved …”
This shows that even though it is spring, the weather seems like it is winter which predicts about an unfortunate omen. Besides, she implies awkwardness that she feels about her life. The man, Zebulon working in the farm makes her feel even more unease.
Rising Action
The incident which is going to happen in the story is shown when Ellie is standing and looking towards the road across the Big Sandy River. The narrator mentions that it is the direction that Ellie’s husband arrives home from the army. “That was the direction Horey would come from when he returned from army. She inadvertently blushed and immediately scurried back in to the house to see to breakfast.” These lines show that she is eager to see her man’s arrival. Moreover, the rising action provides a hint that this story is about Horey’s return after the war. In addition, when Ellie asked about the war from Mr. Franklin, he said that he reckon so and also said, “But you’d best not to get your hopes up too high. They will probably keep men like Horey longer than the rest.”  These lines also offer some clues that there’s no point of keeping much expectations of Horey.
Climax
The turning point of the story can be identified as when the woman receives the black letter which is the death notice of her beloved husband. When I was reading the story, I wanted to see how she would react if her husband died at the war. Thus, at the moment, she saw Mr. Franklin placed the envelope; I happened to think what would be next. Although Ellie needed to see Horey alive, she could only receive a death notification which she could even recognize it without wanting to open it. “The letter was black-rimmed and could only mean one thing. Ella didn’t have to read it to know that her husband is dead.” The conflict of the story is internal because she always struggles with her mind how to deal with society without her husband. “Ella said nothing to him, offering only a very subdued lift of narrow lip.” These lines imply that she doesn’t convey feelings or the tension she has after discovering that her husband is no long alive and she fights with her own heart to deal with her conflict.
Denouement
“When Franklin returned next day, he immediately noticed that Ella’s sleeping stones were missing. As he called out a lukewarm greeting to her, he also noticed someone cutting suckers off the burley several hundred yards away.”


Characters
There are four characters in the story. They are Ella, Franklin, Zebulon and Horey. Among these characters, the protagonist is Ella and the rest are antagonists who play minor roles in the story. Moreover, each and every character contributes to the story in an interesting way. Characters are described separately below.
Ella
Ella is tall and comparatively feeble who is a village woman married to a soldier. She is having a tendency to help others, thinking and eventually despair. She is the protagonist of the story. Moreover, she is defined as a round character because the author has given explanations about her, “She was his opposite in physical appearance (and other ways too), being tall and relatively frail.” “Ella was not a strong person in physical sense, coming from a family of small – boned, tended toward charity, philosophy, and ultimately depression.” In addition, she is a dynamic character because she changes her attitudes over the conflict. The sleeping stones represent her changes. “The sleeping stones went back out the same day. The rock seemed clean and unstained in their perfect smoothness, caressing her hands as she placed them down on the ground in the very front of the yard.” These lines mention that she used to keep sleeping stones before she got the news that her husband was dead. Simultaneously, she left them as she was aware of her husband, “he immediately noticed that Ella’s sleeping stones were missing.” The author has used showing method to present Ella’s character. ““You are right,” she said quickly.” Finally, Ella is a well-developed character in order to make the story interesting.


Horey
Horey is Ella’s husband. However, there is no physical description inserted to this antagonist character. Therefore, it can be mentioned as a flat character. Moreover, there are no information stated about Horey other than he is a soldier. Also it is a static character that plays the Ella’s husband’s role.
Mr. Franklin
Mr. Franklin, who is an antagonist of the story, is a stock and static character because he doesn’t change through the conflict. He is a seventy years old post master. He is helping Ella delivering messages and visiting to see if she is having a fine time. ““You okay Ellie?” Franklin, the seventy-year-old postmaster asked.” However, the author has made use of showing technique to present characters, “Of course, Ellie, the moment news arrives.”
Zebulon
Zebulon is the man who works for Ella in tobacco fields, in corn colleting, and taking care of fences. He is weighty, short man whose hair is untidy who is called as “Zeb.” Moreover, he is a round and static character because the author has described him in detail and he is immutable over the conflict. “The shadow took on the oblong shape of a man; a somewhat overweight and short man, with hair that struck out wildly from one side of his head like a snake lashing out.” In addition, the writer has used showing mechanism when presenting character as other characters. He uses dialogs, “I told you, Ellie, it was too early to turn the stones out. Didn’t I tell ‘e? I like to have frozen last night…”

Setting
This story takes part in a farming village in Kentucky. It shows how hard to get to know what is going on outside of their remote village. “President Lincoln had been dead a full two weeks when Ella found out that the war was over.”  It is implied when Zeb mentions about the work he does in the fields such as working on tobacco, collecting corn. This story begins during spring which is unexpectedly cold for a spring, “spring is not meant to be cold.” Moreover, the story ends during summer which symbolizes the infinite potential for the future which gives warmness.  Weather also provides even darker background to the story.
Point of View
Trammell has used third person limited point of view to make the flow of the story. He only illustrates thoughts of Ella, but he demonstrates dialogs of other characters including Ella. ““Where is the spring?” she thought again, picking up another slab.” When Zeb asked, “Am I hearing you co-rectly, Ellie?” Ellie said, “I want you to go. I’m a married woman.”  These show that the narrator has used third person point of view but he has been limited to Ella’s mind.
Symbolism
Symbolism is the outstanding technique which Trammell has used throughout this story. He has used many symbols to convey certain predictions such as colors, seasons, and weather.  “Spring is not meant to be cold.” This shows that although spring is meant to be refreshing and birth of new, the author has used its unusually cold during the spring predicting that some unfortunate happenings are going to occur. Furthermore, Trammell inserted black color which stands for bad omen at many occasions. For instance, “the letter was black-rimmed…” In addition, the sleeping stones also bear a symbolic meaning which is related to death because they are not just stones but also they are sleeping.
Theme
After effects of war
This story provides information about the Civil War which occurred in United States of America through their conversations. “Wouldn’t you think now that Morgan’s men would be disbanding soon, now that it’s all over?” Although Ella keeps hopes for Horey, Franklin suggests her not to keep high hopes because only a few men return from the war. Moreover, while they were discussing Ella’s five-year-old boy, Horey junior was trying to find out if there were any news available about his father. This illustrates that importance of father for a family. Because of the war, this family had lost their father. This family represents all the women and children who lost their husbands or fathers during the war.
Wife without her husband
This story demonstrates the difficulties a wife has to face when her husband is dead or away from the family. Since, Ella lives in a farming village, she has to work hard in order to make her living. Therefore, there is Zeb to work for her. Besides, Ella requested Zeb to leave because she was afraid of the society that the people would misunderstand her. “I want you to go. I’m a married woman.” Moreover, she thinks that working on tobacco, collecting corn and making fences can be done by her husband, but she will have to do all those activities alone if Zeb leaves when her husband has died. In addition, she has to bring up few children of hers who are not even six-years. She makes her kids’ minds when they ask for their Pa. Accordingly, this short story reveals smoothly how hard the life for a married woman who doesn’t have a husband.
Style
Trammell uses simple diction which can easy to understand the majority of readers. He has make use of techniques such as similes and metaphors. For example, “from one side of his head like a snake lashing out,”  “Ella’s emotions were like spring, long delayed and buried in a layer of frost covering the earth,” “Ella blossomed on a day late in May.” The sentence structure is also simple and has used indirect speech using dialogs. The boy spoke for all of them, “Does this mean that Pa is going to be home?” The author creates a sad tone mixed with anticipation through the story.

Contribution to the science from Copernicus, Kepler and Galileo


During the Middle Ages, there was a golden era for science and technology where the scientific revolution took place. The scientific knowledge began to grow by leaps and bounds. Scientists did many experiments and they concluded through their observations. Among the greatest scientists, Copernicus, Kepler and Galileo involved in a major role.


Firstly, Nicolas Copernicus, who was a Polish scientist, studied and checked status about motion of  heavenly objects. He mentioned after analyzing the observation that we should be in a heliocentric solar system.He also rejected the geocentric theory which the catholic church believed. Heliocentric theory means all the other planets rotate around the sun instead of the earth. Copernicus didn't have clear evidence to prove his claims. Afterwards, he kept it with his until he gets a mathematical and physical proof.

Secondly, Johanna Kepler who was a German mathematician, astronomer and astrologer, studied about most significant applications of physics laws which were related to astronomy. He was able to prove that planets rotate in a elliptical orbits. However, he failed to conclude about the structure about the solar system. He was given many honors for his contribution to the science and technology. Some of the honors are Kepler's law of planetary motion, Kepler asteroid, Kepler's star, and Kepler's crater on the moon.


Thirdly,Galileo Galilee was an Italian scientist. He was a physicist, mathematician, astronomer and a philosopher. Moreover, he is called as father of modern observational astronomy, father of modern physics, father of science and father of modern science. He illustrated that gravity accelerated all objects towards the earth at the same rate. Furthermore, he accepted Copernicus on heliocentric theory. Galileo published Dialogue on the Two Chief Systems in the World which conveys more on heliocentric theory of the universe. He proved his claims with evidence taken from the study of physics.In addiction, he invented the telescope in order to look at the sky.

To sum up, many scientists contributed to this world in numerous ways. Among those characters, Copernicus, Kepler and Galileo play a vital role.They have done their responsibility as scientists.
