These women, ages 61, 72 and 74 years, receiving long-term pergolide therapy for Parkinson's disease or restless legs syndrome, had valvular abnormalities strikingly similar to those induced by fenfluramine, ergot derivatives, or carcinoid. All three had severe, unexplained tricuspid regurgitation; two had predominantly right-sided congestive heart failure; and two had moderate aortic and mitral valve regurgitation. Histology revealed surface fibroproliferative lesions with preserved underlying valve architecture. Carcinoid was excluded, and none of the patients had taken anorectic drugs or ergots other than pergolide.

The thesis studies the difference between GWSs composition and traditional workflow applications, proposes the implement mechanism and technical architecture of GWSs composition and defines the reference model of GWSs composition platform, which provide holistic framework and top-level guidance for studying dynamic GWSs composition technology, designing GWSs composition platform, and implementing representative composite service applications.2、Theories and methods of composite process modeling and process analysis. This thesis proposes a meta-model of Geo-spatial Web services composition process defining from two aspects, i.e. process and resource. According to the process definition meta-model, we propose a new Geo-spatial Web services composition Process/Resource model based on extended WF-net, which effectively resolves the problems on uncertain activity option and dynamic variation of service in composite process model. A notion with regard to soundness of process model is proposed from three aspects, i.e. the structural correctness of process model, validity of data link and validity of resource. The notion of soundness definitely gives a dividing line on correctness of composite GWS process. This thesis analyzes sufficient and essential terms of soundness, and studies compositional property of WSCP/R-net models which provides an effective method to construct a soundness WSCP/R-net model. According to WSCP/R-net, the thesis proposes composition algebra and studies the properties of it. Based on the composition algebra, 6 kinds of composite process reduction rules are induced to optimize the process.3、Geo-spatial Web service QoS model and its application architecture. This thesis proposes an extendable GWS QoS model from three aspects, i.e. Geo-spatial Web Service itself, networking conditions and service consumer which can be used to distinguish GWSs with overlapping or identical functionality. We work over the QoS evaluation methods of composite GWS process which can be used to guide the execution, monitor and service selection of composition process. Aming at some disadvantages in traditional Web service discovery model for its lacking of QoS supporting, this thesis proposes a new service discovery model SDMQ supporting QoS constraints.4、Technologies of composite service executing. SSPL, a new composite service process language, is defined to overcome the disadvantages of existing composite services process languages which can not adapt to the dynamic variation of Geo-spatial Web Services. An algorithm is described to translate WSCP/R-net model into SSPL. The thesis studies the model of dynamic services selection with QoS global optimization, presenting an algorithm GODSS to resolve dynamic services selection with QoS global optimization in GWSs Composition.5、Design and implement experimental system and representative applications. According to the research findings presented above, we design and implement an experimental system and construct two representative applications to show that our achievements are effective and practical.

An image conic can be the projection of either a planar conic or silhouette of a conicoid. We show that at least three images, taken from the same position with different camera orientations, of two planar conics, or two conicoids, or one conic and one conicoid, are needed for the calibration, and a closed-form solution can be obtained. Our new conic based calibration technique requires no knowledge of camera's orientations, and relies solely on image correspondences.

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

In addition to these three topics—the nature of being; the first causes of things; things that do not change—(the latter two being understood as including attempts to show that there no first causes or things that do not change), the topics that fall under the "old" or "Aristotelian/Medieval" conception of metaphysics, we must recognize attention to a large range of "new" or "post-Medieval" topics as no less the proper business of metaphysics than these three.

It is concluded in Chapter Eight that: 1 linguistic proficiencies in three languages play a considerable part in code-switching of EFL teachers in trilingual context; the inter-sentential switching outweighs the intra-sentential switching both in frequencies and percentage; discourse-related switching also outweighs participant-related switching in frequencies and percentage; the EFL is maintained longest in EFL classroom and the language maintained second longest depends upon learners" higher proficiency in Chinese or Tibetan. 2 Ethnic identity and educational background is the major causal factor of EFL teachers" Chinese-English switching in trilingual classroom; duration of language contact and relative trilingual proficiencies are the two principal contributors to the English-Tibetan switching; while Tibetan-English switching is mainly driven by EFL teachers" ethnic identity and education background, as well as the duration of language contact; English-Chinese switching is also largely motivated by the duration of trilingual contact; and Chinese-Tibetan switching is determined by trilingual proficiency to a considerable extent. Meanwhile, psychologically, the switching is mainly motivated by a procedure of psychological projection, trilingual system conceptualization and the mentality of trilingual selection. 3 The educational reflections upon this study indicate: firstly, in trilingual context, the teachers" classroom discourse is characterized by the multilingual involvement, flexibility in strategy option as well as the extension and strengthening of the domination of teachers" discourse. Secondly, the discourse movement and code-switching are largely affected by two cultural ecological mechanisms: enculturation and cultural manipulation. Thirdly, the status quo of EFL trilingual teachers are characterized by unbalanced trilingual proficiencies, poor cultural awareness, and little knowledge of trilingual education and trilingual code-switching, therefore, suggestions are advanced in the end to provide them further education. Fourthly, in trilingual context, the EFL curriculum for ethnic minorities is characterized by plurality of aims, complexity of organization and variety of resources. Meanwhile, it is of great necessity to understand the linguistic values of EFL education for ethnic minority learners. To be specific, firstly, we should not only have a deep understanding of the distribution, construction, function as well as communicative effects of the three languages, but also have a comparative study of the three languages and thus provide the standardization and guidance for the trilingual education. In the end, it is advanced that trilingual EFL provision for ethnic minority should pursue to develop learners" multicultural value system in which first language culture and mother language culture take the central position and EFL culture plays a vital role.
