Last Monday was a sunny day. I got up early in order to get to schoo l early, because it was the first day of a week. On my way to school, I saw a ma n standing beside the street with a walking stick in his hand. He was wondering there and moved slowly. It seemed that he wanted to cross the street. At that ti me, a car passed by and nearly hit him. I ran to him only to find out that he wa s a blind man. It was not easy for a blind man to cross the street. I decided to lead him to the othe… 相似文献

Early one morning a man called for a taxi to take him to the airport, which was a couple of miles down the highway. He patiently waited for about thirty minutes, and called the taxi company again to say that cab had not arrived. This dispatcher assured the gentleman that it was on the way. However, several minutes later, he was still waiting. He had to call a third time, saying, "I need that taxi in a hurry. I have got to make that flight to the West Coast that is due to leave in thirty minutes." 相似文献

The author has undergone a major shift in the way of teaching his undergraduate computer programming courses. In the classroom, the teacher＇s computer is connected to a splitter and a video projector that display the computer＇s screen to the entire class. Using this technology, the programming language itself is used live in class to help the students learn how to program. The students are learning in a context by far livelier than those of previous methods. Teaching computer programming is not achieved by lecturing and writing the program instructions on board or by displaying program instructions to the class on transparencies or slides of electronic presentations. With the implementation of student-centered approaches, the students migrated from the state of passive receivers to constructors of computer programming concepts. Students are coached to develop a sense of exploration, individuality and autonomous thinking. The enthusiasm for technology has been facilitating and supporting the learner-centered approach. Everyone in this approach is a learner, including the teacher. 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

I was born and brought up in the small town of Pineville, which I left at the age of sixteen. Twenty years 1 found myself back on a visit. I went to see my old friend Tom Clark, who, 2 as ever, was chairman of the local 3 . He was busy preparing to welcome a well-known writer, who had been invited to come to 4 a talk on modern literature in the public library 5 evening. Since I happened to have read a book or two 6 the famous writer, when Tom invited me to go with him I 7 accepted. Tom was going to 8 the guest speaker to the audience. Therefore we went to the library a little early 相似文献

Two numerical simulations were performed to investigate the protective effect of the foam cladding. One simulation is based on a previous experimental study, which is a ballistic pendulum with and without a foam cladding subjected to close-range blast loading. The other model is a steel beam with and without a foam cladding under blast loading. The overpressure due to the blast event can be calculated by the empirical function ConWep or by an arbitrary Lagrangian-Eulerian (ALE) coupling model. The first approach is relatively simple and widely used. The second approach can model the propagation of the blast wave in the air and the interaction between the air and the solid. It is found that the pendulum with the foam cladding always swings to a larger rotation angel compared to a bare pendulum. However, the steel beam with an appropriate foam cladding has a smaller deflection compared to the bare beam without a foam cladding. It is concluded that the protective effect of the foam cladding depends on the properties of the foam and the protected structure. 相似文献

There is a hot debate in linguistics and second language acquisition over the extent to which the ability to acquire a second language is naturally connected with age.This article explores whether one's age at which he begins to learn a second language is a contributing factor in his accent.With contrastive analysis,the article comes to the conclusion that it is rare for late learners to have a native-like accent. 相似文献

In this paper we present a regularized Newton-type method for ill-posed problems, by using the A-smooth regularization to solve the linearized ill-posed equations. For noisy data a proper a posteriori stopping rule is used that yields convergence of the Newton iteration to a solution, as the noise level goes to zero, under certain smoothness conditions on the nonlinear operator. Some appropriate assumptions on the closedness and smoothness of the starting value and the solution are shown to lead to optimal convergence rates. 相似文献

With the constant development of Chinese tourism industry,tourism in Chinese economy,accounting for a large proportion.More and more foreign tourists came to China,tour great mountains and rivers,tourist attractions,to understand Chinese national customs.In this way,the community of our translation and foreign-related tourist information guides the work of a higher demand to adapt to Chinese continued integration with the international tourism industry.The translation of tourist attractions in the tourism and cultural presentation plays a very important role.Especially at current time more and more foreign tourists come into China to have a trip.As a result,translation between Chinese and English is vital to this course.Due to the increase of the exchanges between China and the rest of the world,more and more foreign visitors come to China.However,the translation work of our domestic spots hasn’t been done well,and it causes a lot of misunderstanding to the foreign visitors,and influences our international communications.Especially,we will meet a lot of problems of translating the names of scenic spots frequently.Because these name come from different cultures and different countries,it is really hard to translate them properly. 相似文献

For a building structure subjected to impulsive loading, particularly shock and impact loading , the response of the critical columns is crucial to the behaviour of the entire system during and after the blast loading phase. Therefore, an appropriate evaluation of the column response and damage under short-duration impulsive loading is important in a comprehensive assessment of the performance of a building system. This paper reports a dynamic analysis approach for the response of RC columns subjected to impulsive loading. Considering that the dynamic response of a column in a frame structure can also be affected by the floor movement which relates to the global vibration of the frame system, a generic column-mass model is used, in which a concentrated mass is attached to the column top to simulate the effect of a global vibration. To take into account the high shear effect under impulsive load, the model is formulated using Timoshenko beam theory, and three main nonlinear mechanisms are considered. Two typical scenarios, one under a direct air blast loading, and another under a blast-induced ground excitation, are analyzed and the primary response features are highlighted. 相似文献

一 Nearly a week passed before the girl was able to explain which had happened to her. One afternoon she set out from the coast on a small boat and was caught in a storm. Towards evening, the boat struck a rock but the girl jumped into the sea. Then she swam to the shore after spending the whole night in water. During that time she covered a distance from eight miles. Early next morning,she saw a light ahead. 相似文献
