The main work and the originality points of this dissertation could be concluded as the following parts:(1) To analyze systematically the mathematical model of LES of air flow in great space, under the case of isothermal and non-isothermal, as well as the combined action of buoyancy and strain. Some basic problems are studied about the LES application into airflow simulation of great space, such as boundary conditions, spatial difference scheme and time advancing scheme, time step etc., which creates the basis for the LES application to indoor airflow simulation.(2) Both the instantaneous and time averaged flow field of great space with multiple jets under isothermal and non-isothermal cases are explored with large eddy simulation method, and also discussed the dynamic characteristics and the law of fluidflow in the great space.(3) Based on the results of LES of the great space and the Fanger thermal comfort indexes, it is brought forward the concept of the series of dynamic thermal comfort evaluating indexes, which could be divided into thermal comfort index with time averaged properties PD, PPD, PMV, thermal comfort index with instantaneous properties IPD, IPPD, IPMV, and time averaged thermal comfort indexes TAPD, TAPPD, TAPMV, and transient situations time averaged thermal comfort indexes TTAPD, TTAPPD, TTAPMV. The differences among them and the calculation methods are discussed, and the four kinds of indexes are calculated with the thermal comfort index PD as an example.(4) Based on the LES results it is discussed the hot air stratification phenomena in air-conditioned buildings in the case with air supply and return registers on the ceiling and the case on the sidewall. The fundamentals of the hot air stratification are studied and the relations of estimating hot air stratification are brought forward.(5) With the advanced apparatus such as hot wire film anemometer IFA300 and laser particle field anemoscope, corresponding model test and site measurements have been done, which are compared with the simulation results and LES is proved a very promising method in air flow simulation indoor.

With Hilbert space filling curve and latent semantic index, MLSQ maps similar data objects in high dimension semantic space into an adjacent range in one dimensional value space, and considers every data object sequence number in one dimensional space as a key. MLSQ distributes the keys to adjacent nodes of structured P2P systems. By embedding the process of searching data points of HSFC into the nodes of structured P2P networks and using the data search mechanism of networks, MLSQ can facilitate to search the data objects in accordance with query requirements.

Since the above six are self-sufficient man likes to do the job, and the pursuit of self-worth, feel self-care, personal space, respect for another's privacy, pay attention to personal style and taste, do not follow the crowd, there is awareness of the law of "80 After "will consciously dislike these acts: for example, talk to others for no reason," 80 after the "more agreeable to the West are more concerned about the self-opinion, very few non-Road, concerned about others; such as, enjoy preaching others," 80后" from an early age from schools, parents, etc. too much preaching, preaching and therefore acts very much, resulting in antagonistic, their attention; For instance, to belittle the advantages of others,"80 after" consider embodies self-worth is not to derogate others premise, the more The more derogatory of others to explain their value enough, are their attractions; For instance, smoking in the office,"after 80" would be a focus on self and respect for others the organic integration of generation, because these two are not always contradictory, if that "after 80" only know that take care of their own convenience, on the wrong; such as, the mentality of not enough sunlight,"80后" feel self-care, therefore, delighted to do anything on an individual basis or as a premise, we think that good , but their psychological upset, does not endorse, they will not act in accordance with the meaning of the U.S., the ultimate manifestation of personal values on the individual feel, are their characteristics; For instance, loud make personal phone calls,"80, after" personal space, respect for others Privacy, therefore, in a public office area will be less and less to see the "80 after" unscrupulous people talking about the workplace their own affairs, the concept of privacy, especially popular in this generation will be reflected in the workplace in the past.
因为,上述6条都是不够自我的职场中人喜欢做的,而追求自我价值、在乎自我感受、重视个人空间、尊重他人隐私、讲究个人风格与品味、不随波逐流、有法律意识的"80后"会自觉地不喜欢这些行为:比如,无端议论他人,"80后"比较认同西方人较为关注自我的观点,很少道人是非,关注别人的事;比如,喜欢说教别人,"80后"从小受到来自学校、家长等的太多说教,因此对说教行为很反感,从而产生逆反,自己注意;比如,贬低别人优势,"80后"认为体现自我价值不是以贬损别人为前提的,越贬损别人越说明自己的价值不够,是他们的过人之处;比如,在办公区吸烟,"80后"将是注重自我和尊重别人有机结合的一代,因为这两者始终不矛盾,如果认为"80后"只知道照顾自己的方便,就大错特错了;比如,心态不够阳光,"80后"在乎自我感受,因此,任何事情是以个人高兴与否作为前提的,大家觉得好,但自己心理不高兴、不认可,便不会根据大家的意思行事,个人价值最终体现在个人感受上,是他们的特点;比如,大声打私人电话,"80后"重视个人空间、尊重他人隐私,因此,在公共办公区将越来越少地看到"80后"职场人肆无忌惮地谈论自己的事情,隐私的概念在这一代特别流行,将会体现到职场中来。

Formly, HDR casts classification problems and regression problems into a unified regression problem. Clustering is performed in both output space and input space at each internal node, termed "doubly clustered" and discriminants in the input space are automatically derived from the clusters in the input space. A hierarchical probability distribution model is applied to the resulting discriminating subspace at each internal node.
