Multiscale Kalman filters algorithm for GPS commonview observation data based on correlation structure of discrete wavelet coe


Global positioning system (GPS) commonview observation data were processed by using the multiscale Kalman algorithm based on a correlative structure of the discrete wavelet coefficients.


The singlechannel and multichannel commonview observation data were processed respectively.


Methods and applications of 3D wave equation commonazimuth prestack migration


Through coordinate transforming, a commonazimuth prestack tau migration technology that recursively continues the source and receiver wavefields and picks up the migrated results in the twoway vertical traveltime (tau) direction is developed.

 The pterion of 400 Chinese adult skulls, 252 males and 148 females, wasstudied. It was found that the epipteric bone was rather common. When calculated according to A. J. P. von Broek's classification which includes epiptericumanterius, epiptericum posterius, in addition to the most common epiptericumtypicum, the frequency was 42% in terms of number of skulls ed 27% interms of number of sides.

It was found that the epipteric bone was rather common. When calculated according to A. J. P. von Broek's classification which includes epiptericumanterius, epiptericum posterius, in addition to the most common epiptericumtypicum, the frequency was 42% in terms of number of skulls ed 27% interms of number of sides. The frontotemporal suture type, however, was smallin number (3.0% in terms of the number of skulls and 1.75% in terms of thenumber of sides), due to the presence of a frontal process of the temporalbone. Both the epipteric bone and the frontotemporal suture were found to bemore common in the female than in the male. Various theories regarding theorigin of these alterations are introduced and discussed.  检查了400个中国成人头颅的翼上骨及额颞缝,以侧为单位计算,发现翼上骨的数目为216侧合27%,以头颅为单位计算,发现翼上骨的数目两侧者48例(两侧同型及非同型)一侧者120例共168例合 42%,男女分开计算,以侧为单位,男性23%,女性33.8%,以头颅为单位,男性35.71%,女性52.7%,女性占多数。额颞缝以侧计算共14例合1.75%,以头颅数计算,两侧者2例一侧者10例共12例合3%。我们这个工作承张鋆教授的指导特此志谢。  A brief mosquito survey was made from Hainan Island and the Leichowpeninsula of Kwangtung Province during April and May, 1953. Collections were madeon adults as well as on larvae and pupae from various habitations. Altogether 31species were discovered. They included: (1) Aedes aegypti, (2) Aedes albopictus(3) Aedes scutellaris (4) Aedes togoi (5) Aedes vittatus (6) Culex fatigans (7) Culextritaeniorhynchus (8) Culex bitaeniorhynchus (9) Culex vagans (10) Culex vishnui(11) Culex mimeticus (12) Culex mimulus (13)...

In the hilly regions A. minimus and A. jeyporiensis wereby far the commonestspecies found in human dwellings while A, hyrcanus var. sinensis was less common.In the coastal regions the reverse was true. A key for the identification of all species of mosquitoes reported up to thepresent from Hainan Island was given.  1.本文叙述1953年4月至5月作者参加海南岛与雷州半岛蚊类采集调查情况,共获蚊类31种,将其地理分布与捕集场所详加描述。 2.本文将以往海南岛与雷州半岛的蚊类调查研究的文献作总的温习并扼要列举之。 3.本文内将海南岛及雷州半岛的地理环境与蚊种的分布情况。加以讨论。 4.最后将海南岛已知蚊种编为检索表以便研究及参考。  Single storied industrial buildings composed of steel trusses and reinforcedconcrete columns are very common. As the upper joints are hinged, the stresses in the columns are not influenced by the elastic properties of the trusses; while the upper joints are rigid, methods of analysis are usually based on the assumption that the moment of inertia of a steel truss may be taken as equivalent to that of a beam. In this paper, the author making use of the principle of least work reviews the equations for calculating... Single storied industrial buildings composed of steel trusses and reinforcedconcrete columns are very common. As the upper joints are hinged, the stresses in the columns are not influenced by the elastic properties of the trusses; while the upper joints are rigid, methods of analysis are usually based on the assumption that the moment of inertia of a steel truss may be taken as equivalent to that of a beam. In this paper, the author making use of the principle of least work reviews the equations for calculating the anglechanges at the ends of a truss, and then illustrates their applications with two practical examples: one with flat roof and the other with gabledroof. They are solved respectively by the method of slopedeflection for the cases of nosidesway, sideswaycorrection and sidesway included by solving the elastic equations of unit deformation. The results are compared with those obtained with usual assumptions.  單層廠房採用鋼架砼柱之混合結構,極為普遍,上端鉸結時柱之應力並不受桁架彈性常數之影響,上端剛結時之分析方法,對於鋼架之截面慣矩每予假定,並代之以假想變梁,本文作者用最小功能定律以求計算桁架兩端角變常數之公式;再取二實例:一平頂屋架,一脊式屋架,用角變位移法分就無側欹、侧欹校正及單位變位彈性方程解三步驟解出共結果,與一般假定方法所得相互比較。   << 更多相关文摘
