The motion of Ships is complex due to combination of control forces and external forces. Hydrodynamic perturbations are also induced from ship motions. The external forces are a combination of wind, waves and sea currents. The control system perturbation is defined by propulsion and steering system of ship [1]. The ship motion is non-linear due to resultant forces obtained from the combination of external forces and control system. Ship motions is defined by six degree of freedom in sea. According to [2], six degree of freedom divided into linear motion and rotational motion of ship in three directions (X, Y, Z axis).In most practical situations, the forces acting on the ship due waves and wind are very complex. This makes hard to expect …show more content…
Ships are the backbone of any maritime business. The working environment as well as the stability of ship in ocean will be affected due to the continuous perturbation from the sea environment The instability of ship motion may lead to unexpected accidents. The direct impact of such incidents is human. Beside human, the other important factors include the lives of ocean creatures, severe economic loss and pollution in marine environment. Because of complexity in ship motion we need to be aware every time. It is possible to use prediction model like neural network to see the possible motion of ship in the future. The predicted motion will be helpful for captain to control the ship for safety. The experienced knowledge on ship behavior is quite important to maneuver the ship towards the safe destination. The prediction model can predict any ship activities which can be very useful for captain for controlling the control system forces. The controlling forces mean captain can increase the efficiency of ship propeller, engine and fuel. Therefore, the prediction of ship motion is important for human safety, loss of economy and eventually to increase the efficiency of …show more content…
Most important and key technique, such as information fusion, danger prediction technology traffic flow estimation and etc., cannot work without it. So the prediction of future time step for maneuvering of ship will be useful to implement the control forces accurately. The research based on the application of artificial intelligence such as Neural Network, Genetic Algorithm and Fuzzy Logic have shown the great potential for the prediction of ship behavior. A lot of interesting work has been carried out such as Ship Roll Motion Time series forecasting [4],online ship roll motion prediction [7], ship motion prediction [8], Ship trajectory based on Back propagation Neural Network [9] and Ship path following [10].The related work will be discussed in section 2.2. From [4], [7], [8], [9] and [10] it shows the great potential to implement the Artificial Neural Network (ANN) for the behavior of

On August 29th, 2005, Hurricane Katrina, the most expensive hurricane in American history, made landfall in Louisiana with winds of one hundred and twenty-seven miles per hour (“Hurricane Katrina Statistics Fast Facts”). The sheer magnitude of the amount of lives and property lost was enormous, and it was triggered simply by warm ocean waters near the Bahamas ("How Hurricane Katrina Formed"). Nature was indifferent to whether the raging winds and rain would die off in the ocean or wipe out cities; it only follows the rules of physics. A multitude of American authors has attempted to give accounts and interpretations of their encounters with the disinterested machine that is nature. Two authors, Stephen Crane and Henry David Thoreau, had rather contrasting and conflicting interpretations of their own interactions with nature. Crane’s work, “The Open Boat,” is story based on his experience as a survivor
I’m applying to SEA Semester, because I love the ocean. It’s been my dream from a young age to learn to sail and live on a ship. I’m from Aroostook County in Northern Maine, which is five hours away from the ocean. Every summer my parents would make sure I got to the ocean at least once, and I’ve romanticized it since I can remember. Since coming to Bowdoin, I’ve always spent my weekends biking and driving to the ocean, because it’s become a place for me to think clearly and escape the fast-paced life of a college student. The ocean has developed into my happy place, which is why I want to study it and understand how humans are impacting it. I want my undergraduate studies to give me the knowledge needed to protect our oceans in the future, and to be able to conduct research to expand our knowledge of the ocean. To be able to live on a tall ship and continue my studies of the ocean is my dream.
“The Boat”, narrated by a Mid-western university professor, Alistar MacLeod, is a short story concerning a family and their different perspectives on freedom vs. tradition. The mother pushes the son to embrace more of a traditional lifestyle by taking over the fathers fishing business, while on the other hand the father pushes the son to live more autonomously in an unconstrained manner. “The Boat” focuses on the father and how his personality influences the son’s choice on how to live and how to make decisions that will ultimately affect his life. In Alistair MacLeod’s, “The Boat”, MacLeod suggest that although dreams and desires give people purpose, the nobility of accepting a life of discontentment out weighs the selfishness of following ones own true desires. In the story, the father is obligated to provide for his family as well as to continue the fishing tradition that was inherited from his own father. The mother emphasizes the boat and it’s significance when she consistently asked the father “ How did things go in the boat today” since tradition was paramount to the mother. H...
The Chinese navy in the early 1400’s was very powerful but unfortunately it grew weaker and weaker over time. The cause of this was that China ran into political problems which prevented future voyages.
Not many know about Dragging Canoe and the battle he fought during the American Revolutionary War. The Native American’s role in the Revolutionary War was very important, but not well known. As a result, the Revolutionary War can come across as one-sided. Dragging Canoe fought for the Native American’s existence in the colonies. First, he was strongly opposed to Henderson’s Purchase or also called the Transylvania Purchase. Secondly, Dragging Canoe’s raid at “Battle of the Bluffs” became an issue for the colonists. And lastly, there was negotiating done between the British and Colonists would somehow effect Dragging Canoe, his warriors, and the future for the Native Americans.
This passage defines the character of the narrators’ father as an intelligent man who wants a better life for his children, as well as establishes the narrators’ mothers’ stubbornness and strong opposition to change as key elements of the plot.
Artificial Intelligence (AI) is one of the newest fields in Science and Engineering. Work started in earnest soon after World War II, and the name itself was coined in 1956 by John McCarthy. Artificial Intelligence is an art of creating machines that perform functions that require intelligence when performed by people [Kurzweil, 1990]. It encompasses a huge variety of subfields, ranging from general (learning and perception) to the specific, such as playing chess, proving mathematical theorems, writing poetry, driving a car on the crowded street, and diagnosing diseases. Artificial Intelligence is relevant to any intellectual task; it is truly a Universal field. In future, intelligent machines will replace or enhance human’s capabilities in
the ship such as: mathematics, navigation, the operations of a ship, and how to read
I personally found this book to be an excellent read, and while I haven’t read to many business management books. I can feel safe to say that I think this one does an excellent job in conveying key management principals for today’s workplace. It also appealed to me due to my fascination with the way in which our military operates. I believe he did a great job of staying clear of getting too detailed in either is leadership model and military jargon. I would recommend this book to anyone who feels intimidated by management books that read more like a textbook, who want to learn but also enjoy the reading too.
No Bricks and No Temples: Coping with Crisis in “The Open Boat” Stephen Crane’s story “The Open Boat” concerns four people who are trying to reach land after surviving a shipwreck off the Florida coast. During the course of the story, they face dangers that are real physical threats, but they also have to deal with trying to make sense of their situation. The characters in this story cope with their struggles in two ways: individually, they each imagine that Nature, or Fate, or God, is behind their experiences, which allows them to blame some outside force for their struggle, and together, they form a bond of friendship that helps them keep their spirits up. . In “Becoming Interpreters: The Importance of Tone in ‘The Open Boat,’” Gregory Schirmer states that “‘The Open Boat has at its center two quite different views of man: as a helpless and insignificant being adrift in a universe that is wholly indifferent to him and his ambitions, and on the other hand, as part of a brotherhood that binds man to man in the face of that indifferent universe” (222).
Summary- This book expert describes the fundamentals, history, and changes associated with Artificial Intelligence from 1950’s onward. The book provides a basic explanation that Artificial Intelligence involves simulating human behavior or performance using encoded thought processes and reasoning with electronic free standing components that do mechanical work.
From an adolescence age, the desire to service my country is that of great immensity within myself. I learned from my Mother’s philosophical mindset that an individual’s country comes first and foremost. Witnessing the ferocity, the terrorism, the ghastly acts committed upon humanity and the United States has only invigorated my unbending aspiration to serve.
In ancient marine times people built boats out of bamboo, bundles of reeds, air filled animal skins and more. One of the first boats was made out of sticks and put together with sewn hides. Also at the time then didn’t have oars invented yet so people would use their hands to make the boat move. And to move the rafts they would push poles against the bottom of the rivers or lakes. Then they came out with sails which would replace the action of the humans and sail boats could take on longer trips and heavier loads rather than just the boats make out of sticks. Then they came out with the Viking long ships, those would be about 30 meters long made out of overlapping planks of oak wood, held together by iron rivets. Each ship would carry about 60 oarsmen who rowed the ship. Next they came out with the Chinese junks which were constructed out of softwood and had a horse shaped stern. And their sails weren’t like most, instead of squares they were more built pointed on the top and squared at the bottom. Then they had the three and four masted sailing ships which were in service for several centuries and these wooden ships were used for battling. Then we came out with the clipper ships which were fast sailing ships with long slim hulls and tall masts. Next they came out with the steamships so instead of sails and oars to power it, it was combined with wind and wind power. Then they had the ocean going liners which were driven by a propeller and made of iron. And they came out with the steam driven boats which had paddles on the side of them. Next the sailing ships were converted to diesel power so that they would use oil instead of steam. ...
the hull is called friction. This slows the boat down. If a boat hull is designed
