civilization without toys

There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.
　　In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.
　　What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same.　The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the word and their persistence to the present that is amazing. In Egypt, America, China, Japan and among the Arctic people, generally the same kinds of toys appeared. Varations depended on local customs and way of life because toys imitate their surrounding. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.
　　Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the cart to the automobile is a direct line of ascent . The progress from a rattle used by a baby in 3000BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.

needs packaging

A person, like a commodity , needs packaging. But going too far is absolutely undesirable. A little exaggeration, however, does no harm when it shows the person’s unique qualities to their advantages. To show personal attractiveness in a casual and natural way, it is important for one to have a clear knowledge of oneself. A skilled packager knows how to add art to nature without any signs of embellishment, so that the person so packaged is not a commodity but a human being, lively and lovely.
　　A young person, especially a female, shining with beauty and full of life, has all the favor granted by God. Any attempt to make up would be self - defeating. Youth, however, comes and goes in a flash. Packaging for the middle - aged is primarily to hide the marks made by years. If you still enjoy life enough to keep self - confidence and work at pioneering work you are unique in through plains mountains and jungles, running its course as it should. You have really lived your life, which now arrives at a self - satisfied stage of quietness and calmness with no interest in fame or wealth . There is no need to make us of hair dyeing. The snow - capped mountain is itself a beautiful scene of fairyland. Let your looks change from young to old in step with the natural ageing process so as to keep in harmony with nature, for harmony itself is beauty, while the other way round will only end in unpleasantness. To be in the elder’s company is like reading a thick book of deluxe （better quality）edition that attracts one so much as to be unwilling to part with.
　　As long as one find where on stands, one knows how to package oneself, just as a commodity sets up its brand by the right packaging.

OFDM and MIMO

In the next generation wireless communication systems,OFDM and MIMO system is widely used for the demand of higher transfer rates and lager system capacity. It challenges the channel estimation technique a lot.The channel estimation method based on men's nike shoes training sequence offers less complexity and better performance.In this thesis sequence-based OFDM-MIMO channel estimation is discussed.The main work is just as follows:The thesis begins with the introduction to basic concept and method of channel estimation ,OFDM and MIMO women's nike shoes system model is summarized.Then channel estimation based on some kind of training sequence and channel estimation under constraints is discussed.The results of simulation is given.The thesis lays an chi flat iron emphasis on the design of the training sequence,for the training sequence influence the quality of the channel estimation.(1)The wireless communication channel characteristic and basic channel estimation chi hair straighteners methods are summarized.(2)MIMO ,OFDM system and channel model are given,and several kinds of channel estimation methods based on training sequence are presented.(3)MIMO channel estimation based on complementary Golay sequence is discussed,and simulation result is given.From theoretic analysis and simulation result,it achieve a better performance.(4) Implicit MIMO channel estimation based on ZCZ training sequences is discussed. by choosing properly a set of ZCZ hair straighteners sequences with balanced property, the harmful dc-offset can be completely removed, thus exhibiting significantly better estimation performance and resulting in simpler implementation when compared with the conventional implicit training schemes without dc-offset elimination and with dc-offset elimination based on perfect sequences.(5)OFDM-MIMO channel estimation based on training sequence under constraints is discussed. A method of designing near-optimal training sequences using nonlinear optimization techniques is proposed.The research of the thesis can provide some good references to the wireless mobile communication systems design. It ends with the possible direction for the future research.
