structure for a receiver in UWB communication

So, there’s always going to be a challenge in the design of structure for a receiver in UWB communication systems.In dense multi-paths environment, the transmitted signal power is distributed to too many multi-path components, however, these multi-path components which can be resolvable in time domain may speed up the acquisition process. This is because we assume that the acquisition is completed when any one of the multi-paths is acquired in the acquisition stage. Based on this assumption, the true phase position can be found rapidly once the coarse synchronization of the receiver located the multi-path cluster in the search space.We research the characterization of the multi-path channel firstly, and analyze the acquisition performance of the several search methods. Then introduce the process of serial search. Based on these theories, we propose two algorithms for acquisition in dense multi-path environment. Both of these two algorithms divide the search space into several subspaces, then find the subspace which include the true phases rapidly in the first step and locate the true phase in the second step within that subspace. From the result of simulation, we can see that both of the algorithms can complete the acquisition rapidly with low mean search time.

Should the University Campus Be Open to Tourists?

Nowadays, many famous university campuses have become one of the popular tourist attraction. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. Everyone wants to get cheap Lacoste POLO Shirts.In the place far away from the capital city, the local students also visit the universities famous in their own province.
　　So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions.Are there polo shirts you would like? On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university.Here is the best northface outlet! On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere. In my opinion, the tourism to the universities is not a good thing.
　　The campus is mainly a place for study . With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.

Student Service Clubs

Nowadays student service clubs are indispensable on college and university campuses as long as there are any clubs in a school. People served by these clubs are various: mountain people, fishing villages, farmers, handicapped people and broken families. But in recent years the clubs have received much criticism and reproach. In fact. In spite of some systematic defects, they have performed many services for lots of disadvantaged and remote communities throughout Taiwan. I feel the need-the need for cheap Wholesale nike shoes！ Every summer and winter vacation the clubs send ten to twenty members to one local place (all the costs are paid by the members themselves— one to two thousand N.T. dollars at one time). The students make home visits to understand the problems confronting the local people. The common problems are: (a) they still have very conservative ideas about children's education or youngsters' marriage or savings, (b) they lack a channel of communication with the government, and (c) some secluded paces don't even have street lamps yet; one can imagine how horrible it is to walk on the narrow dusty road at night. Their systematic drawbacks are a great hindrance to the service work. Because the members are all students, they can only go when there is no burden of study. Cheap Nike shoes are very nice here! The two visits in a year inevitably become a “seasonal disturbance” to those poor people. Owing to the restriction of study, one member maybe will have only one or two chances and the local people have to get acquainted with “new friends” every vacation without knowing why. So, the service work is forced to start at the same point every year with no improvement, another serious problem is that some members are ill trained. They not only can't help others but also can't help themselves: that is to say. The sometimes are too conceited to learn anything, including self growth. Sometimes they become tourists—not doing service, but taking pictures, appreciating scenery. Perhaps the criticism is right, students don't have the qualification to "help" other people. But, at least, they've brought much new information into the remote counties and given the closed communities much stimulation as well as the opportunity of introspection. Maybe one doesn't believe all this, but there is one thing which can't be denied: friendship, yes, friendship. I love northface jackets.These two groups of people no longer belong to two different worlds. the most important thing is that the people served know city people, care about them.

3D free

In this paper a new solution to the 3D free form object recovering problem is presented. A vision systembased on a manufactured grid projector and a CCD camera is conceived to achieve Lacoste Polo Shirts.Calibration procedure of such a system is also studied. A robust sub-pixel model based approach toextract grid nodes from captured images had been developed and used in both camera calibration and 3Dpoints reconstruction procedures. The Cheap Lacoste Polo Shirts obtained from experimental tests demonstrates the accuracyof obtained 3D measurements (less than 1%). This result is crucial for the object pose recovering, since itallows to well reconstruct local surface patches and so to generate matching hypotheses more precisely.The possibility to control the projector’s orientation allows to scan particular local regions of the objectand therefore extract 3D surface Lacoste Shirts which are exploited to perform 3D object recovering.
