Yasser Arafat dreamed of creating a Palestinian state since he was a young man in Egypt smuggling guns into Palestine. Yet after six years as the president of the Palestinian Authority, an entity established as a step toward the goal of independence, Arafat has been unable to turn his dream into reality. To Palestinians, he is the symbol of their struggle for a homeland. Yet to Israelis, he is the symbol of the threat to destroy their homeland. 相似文献

INTRODUCTION The stunning growth in storage technology prompted Prof. Raj Reddy of Carnegie Mellon University to envision that it would be possible to store in digital form, in the very near future, all knowledge ever acquired by the human race. As part of this grandiose vision and as a first step, in realizing this vision, it was proposed to create the Digital Library with a free-to-read, searchable collection of one million books, predominantly in Indian languages, available to every… 相似文献

On July 20, 1969, Neil Armstrong became the first human being to set foot on the Moon. He was the commander of the Apollo 11 lunar module, and was accompanied by Edwin Aldrin. His first words after stepping on the moon were, "That's one small step for a man, one giant leap for mankind."1 This event was televised to Earth and seen by millions! Armstrong was born in Wapakoneta, Ohio in 1930. He was on a plane for the first time at the age of six. He took flying lessons in his teens and got… 相似文献

The Call of the Wild is one of the representative works of the American writer Jack London.It was published in 1903.Once appearance,it quickly achieved great success for its beautiful language and multiple levels of the theme.Based on the industrialised and capitalistic society in American history,this novel vividly reproduces the Gold Rush in Klondike.The main plot describes a process of how a domesticated dog degenerated into a wild one and went back to nature.The hero Buck is endowed with human senses and characteristics,for London tried to use animal characters to illustrate moral precepts and exhibit human behaviours.The thesis intends to demonstrate the fascination of this great novel on one hand and on the other hand, to disclose the cruelty of the social reality at that time,in hope of providing a profound comprehension for the readers. 相似文献

My grandparents were married for over half a century, and played their own special game from the time they had met each other. The goal of their game was to write the word"shmily" in a surprise place for the other to find. They took turns leaving "shmily" around the house, and as soon as one of them discovered it, it was their turn to hide it once more.They dragged(拖,拉) "shmily" with their fingers through the sugar and 相似文献

The objective of this study was to investigate the tempo-spatial distribution of paddy rice in Northeast China using moderate resolution imaging spectroradiometer(MODIS) data.We developed an algorithm for detection and estimation of the transplanting and flooding periods of paddy rice with a combination of enhanced vegetation index(EVI) and land surface water index with a central wavelength at 2130 nm(LSWI2130).In two intensive sites in Northeast China,fine resolution satellite imagery was used to validate the performance of the algorithm at pixel and 3×3 pixel window levels,respectively.The commission and omission errors in both of the intensive sites were approximately less than 20%.Based on the algorithm,annual distribution of paddy rice in Northeast China from 2001 to 2009 was mapped and analyzed.The results demonstrated that the MODIS-derived area was highly correlated with published agricultural statistical data with a coefficient of determination(R2) value of 0.847.It also revealed a sharp decline in 2003,especially in the Sanjiang Plain located in the northeast of Heilongjiang Province,due to the oversupply and price decline of rice in 2002.These results suggest that the approaches are available for accurate and reliable monitoring of rice cultivated areas and variation on a large scale. 相似文献

Birds can learn to choose the best building materials for their nests,according to scientists.It was previously thought that birds’choice of nest materials was determined by their genes,that is,each type of bird has their own methods of building nests born with them.But an experiment has now shown this to be a more complex activity.The study,published in the Royal Society Journal Proceedings B, 相似文献

We describe the green space system planning and design of a new Kaixian City for migrants in the Three Gorges Reservoir area of P. R. China. The goal of the project was to provide a high quality settlement for migrants relocated from the old Kaixian City that had a history of over one thousand years and from other places with different traditional cultures. Our efforts focused on conceiving affordable strategies to increase green areas, improve waterfront landscapes, deal with water level fluctuation, integrate diverse folk cultures, and encourage bicycling as an environmentally-friendly form of urban transportation. The new city is anticipated to benefit from the green space systems with an improved eco-environment, enriched tourism resources, cheap landscaping costs, relief from traffic pressure, and in other ways. The planning philosophies employed could be useful in the engineering and construction of other cities in the Three Gorges Reservoir area. 相似文献

The term, culture shock, was introduced for the first time in 1958 to describe the anxiety produced when a person moves to a completely new environ- ment. This term expresses the lack of direction, the feeling of not knowing what to do or how to do things in a new environment, and not knowing what is appro- priate or inappropriate. The feeling of culture shock generally sets in after the first few weeks of coming to a new place. "Coming to America is like jumping into cold water," says an inte… 相似文献

INTRODUCTION The huge amount of data collected and stored in databases increases the need for effective analysis methods to use the information contained implicitly there. One of the primary data analysis tasks is cluster analysis, intended to help a user understand the natural grouping or structure in a dataset. Therefore, the development of improved clustering algorithms has received much attention. The goal of a clustering algorithm is to group the objects of a database into a set of m… 相似文献

Neural network and genetic algorithm based global path planning in a static environment 总被引：3，自引：0，他引：3
INTRODUCTION The path planning problem of a mobile robot is to find a safe and efficient path for the robot, given a start location, a goal location and a set of obstacles distributed in a workspace. The robot can go from the start location to the goal location without colliding with any obstacle along the path. In addition to the fundamental problem, we also try to find a way to optimize the plan, say to minimize the time required or distance traveled (Wu et al., 1996; Sadati and Ta-he… 相似文献

Samuel Johnson (1709——1784) is a famous English essayist, literary critic and dictionarycompiler. In 1747, when Johnson began his "Dictionary of the English Language", Chesterfieldhad at first indicated that he could be his patron, but when Johnson came to him for concretehelp, Chesterfield neglected him to the point of ignoring him. Johnson was insulted and furious.In 1755, when Johnson's Dictionary was published and acclaimed after seven years of hard work,Chesterfield openly recommended it, hoping to get some credit for it as Johnson's patron. John-son at once wrote his famous letter in a sharp style, opeply denying Chesterfield's patronage, andattacking him outright for his behaviour. The attack, however, was made in a circumlocutiousway. 相似文献

Captain James Cook made his name as a world-famous explorer. It was Cook who represented the British in first travelling to New Zealand and Australia, paving the way for the British to venture further into these lands.The year was 1768 when the British government had a special force of explorers sent to discover for the British new lands in the southern part of the world. The leader of this expedition was James Cook.Firstly, he discovered New Zealand for the British. Then, it was Australia. There were already the original human inhabitants of these lands, so, morally speaking, Cook was not right in helping his government try and take over these lands from the natives.According to reliable sources , James Cook was the first European to land on Hawaii. However, it was at this place that he died tragically. He was killed by a few of the natives there. It happened in 1779. 相似文献
