Pacific Canadian Railroad :: essays research papers fc
Canadian Pacific Railway Development      This article was about the Canadian Pacific Railway. For over 100 years, the railway has practiced a tonnage based shipping model. Trains were to wait in their yards until there were enough shipments to justify a train journey from one point to another. The result of this method was that very few trains traveled, and that the trains that did travel were never on a regular schedule. This resulted in much inefficiency for the company. Some of the issues were trains were sitting in yards with half full loads for days, yard workers having inconsistent shifts and sometimes sitting around in case a train might leave that day, and most importantly, customers were uncertain of delivery times for their goods. The â€Å"efficient†movement model resulted in poor customer satisfaction and a rather large set of excess equipment such as train cars, locomotives, and workers. As a result, the profit of the Canadian Pacific Railway (CPR) was very low and the company decide d it was time for a new model.      CPR hired MultiModal Applied Systems to help them formulate a solution. This solution was to have the guiding goals of more consistent train schedules, and higher customer service. The new approach was based on a small stepladder of models, which built off each other to form the final product. The first model was the block approach. A block was a group of cars with the same departure point and destination. The model worked to find how blocks of cars could be easily combined and separated in yards so that the most blocks possible, were moving at all times towards their final destination. Previously, trains had stopped at many or all yards along their long journey. Now, with the blocking model, some yards were bypassed and others were used with varying frequencies to help balance the workload of the yards and to make for more efficient paths for the blocks to travel on. This model had constraints based on the distance a block would travel compared to its shortest po ssible path, the busyness of yards, and the maximum length that a train could be. This model was worked on and reworked on a weekly basis, as new shipments were created, and thus each week a block would travel the most efficient path it could without over extending any other set of blocks.      Outside or on top of the block model was the train model.

An Analysis on “The Pedestrian†Essay
In â€Å"The Pedestrian†Ray Bradbury wanted to portray an event that happened one night while taking a walk with a friend, stopped by a police officer who didn’t get why they was walking and stated â€Å"Well don’t do it again†(Person 50). The characterization and symbolism in this short story demonstrate how society might turn out when humankind depends upon technology. â€Å"We have too many cell phones. We’ve got too many internets. We have got to get rid of those machines. We have too many machines now†(time 1) even today Bradbury shows his distrust in technology through this quote given a month before his 90th birthday. Ray Bradbury’s â€Å"The Pedestrian†shows his own distrust of technology, and view of how society will end up if to reliant on technology. Through characterization, Ray Bradbury shows that if humankind advances to a point where society loses all humanity, then humankind is better off ceasing to exist. Mead is in many ways Bradbury’s only true representation of humanity left in the year 2053 A.D., through describing him as have a â€Å"shadow of a hawk†(26), which relates him to a wild free spirited bird. Mead is also seen as humanity because he is associated with light, which is symbolic for soul, Meads house beams â€Å"loud yellow illumination, square and warm in the cool darkness†(29). While the loss of humanity is displayed in the â€Å"lone†â€Å"metallic voice†that the robotic cop car has and in the descriptions of the towns’ people being â€Å"gray phantoms†that live in â€Å"tomblike buildings†in a â€Å"graveyard†of a town showing how the life of the town dies with the sunset(25-26). In multiple ways one can see how Ray Bradbury is Mead himself. Bradbury’s love for writing can be related in essence to Meads love for walking. While Mead and Bradbury are directly related due to both of them are writers. Bradbury stated â€Å"[Television is] a really dreadful influence on all of us†while Mead doesn’t even own a television which relates in a way that they both dislike the television altogether. The short story shows the not too distant future in an unfavorable light. The once free thinking society has been corrupted by the simple convenience of technology. Bradbury shows his own distrust by demonstrating how technology will make humankind lazy and useless. As shown in the title walking has become obsolete, Mead is not a pedestrian; he is, in a city of 3 million people (27), the pedestrian. Bradbury demonstrates that if not controlled, technology in the near future will do as it wants, when it wants. In this short story Bradbury demonstrates how the television has destroyed literature and society as well through Meads thoughts â€Å"Magazines didn’t sell anymore. Everything went on in the tomblike houses at night now†, â€Å"the tombs, ill lit by television light, where the people sat like the dead†(28, 29). While also showing through the cop car how writers job is not the only job ceasing to exist by stating â€Å"the force had been cut down from t hree cars to one. Crime was ebbing; there was no need now for the police†(27). Works Cited Bradbury, Ray. â€Å"The Pedestrian†. 1951 Friedman, Megan.

Harriet Tubm One Of The Most Important Women - 1783 Words
Playing a vital role in helping the slaves escape from their unfortunate fate, Harriet Tubman is one of the most important women in the history of slavery. In 1820, in a little county named Dorchester, a daughter born to Ben Ross and Harriet Green would one day be called the savior of slaves; her parents, on the record, named her Araminta Harriet Ross, and then nicknamed her â€Å"Minty†. Since both parents were enslaved on Anthony Thomas and Mary Pattison’s plantation, there is no official record of Harriet’s birthday. Historians believe that she was born somewhere between February and March in 1820. During the year of 1892, Harriet announced to a crowd of people that she was sixty-seven years old; however, it is possible that this year is not†¦show more content†¦Minty’s parents met during the year of 1803 after the merging of Thompson’s and Brodess’ plantations. According to Harriet Tubman Chronology, during 24 years of their mar riage, they were successful at creating nine children of their own: the oldest Linah (born in 1808), Mariah Ritty (1811), Soph (1813), Robert (1816), Araminta (1820), Ben (1823), Rachel (1825), Henry (1830), and last but not least, Moses (1832). Even though Mr. Ross was released from slavery at age 45, he willingly worked for Thomas for income. When Minty’s younger sister, Rachel, was born, the Brodess plantation was not financially stable. Even though Brodess’ slaves meant a lot to him, he had to start selling off his slaves in order to keep his plantation going; the first ones that were sold was Araminta’s older sisters Mariah, Linah, and Soph. When Minty turned the age of five, she started being deprived of her own childhood memories when she became forced to take care of her owners’ infant. Being too young to accept such responsibility on top of all of her household chores, she stayed on duty all night long most nights. She had to hold the baby in h er arms, and rock her while she slept in order to avoid the risk of the infant crying. If the baby made a cry, her mistress would whip her around the neck out of lack of caring for her child the way she should.
