A scheme for building detection and reconstruction from LIDAR data is presented with an object-oriented method which is based on the buildings’ semantic rules. Two key steps are discussed: how to group the discrete LIDAR points into single objects and how to establish the buildings’ semantic rules. In the end, the buildings are reconstructed in 3D form and three common parametric building models (flat, gabled, hipped) are implemented.展开更多

However, ＂function is converted to symbolic sign＂ as a model of thinking is a reflection and return of the traditional culture to the spirit of the times, and it carries forward the essence of the nation.展开更多

This, however, fails to embrace a unanimous acceptation by scholars thereafter and the debates over linguistic signs in terms of arbitrariness and motivation, due to the regrettably understood terms, have imbued the development of linguistics, nurturing a myriad of sustainably productive branches in linguistic studies. Based on refreshing interpretation of the key terms, the paper adopts an integrative and dialectical approach to linguistic signs and argues that arbitrariness is more a matter of degree than one of presence or absence, hopefully to bring home that duality as whole features linguistic signs fundamentally.展开更多

The authors find that in a short duration there is a significant difference between the effect of bilingual （English ＆ Chinese） explanation and that of monolingual （Chinese） explanation on the students＇ recognition of English new words.展开更多

In the introduction, l will propose an historical reconstruction of the debate, and focus in particular on Russell and Kripke＇s treatments of proper names. Strong criticisms will be advanced against Kripke＇s hypothesis of rigid-designator and, more deafly, against the consequent distinction between the epistemic and metaphysical level that Kripke proposes to explain identity assertions between proper names. Furthermore, I will argue, that, pace Kripke, Russellian treatment of proper names allows to capture all our semantic intuitions, and also those semantic interpretations which concern context-belief sentences. I will close the introduction by focusing on a criticism that Kripke rightly points out against an example that Russell proposes in his On Denoting. Section 2 will be devoted to Russellian solution： I will show that not only Russell＇s logical treatment of proper names allows to answer to Kripke＇s criticism to Russell＇s example, but also that such treatment can disambiguate and express all our semantic intuitions about Frege＇s puzzle sentence ＂Hesperus is Phosphorus.＂ ! will then show that, contrarily, Quinian solution （discussed in section 3） and Kripkian one （see section 4） are not satisfactory to capture our semantic knowledge about Frege＇s sentence. Furthermore, in section 5, I will focus on Kripke＇s distinction between epistemic and metaphysical level to deal with identity assertions between proper names, and I will logically show that such distinction is not plausible. In section 5, then, I will show that Russellian solution allows to explain context-belief sentences, contrarily to what Kripke thinks. In Conclusions, I will summarize what 1 have argued in the text.展开更多

文摘Extraction of buildings from LIDAR data has been an active research field in recent years.

文摘Brick and tile were originally the building components for meeting a certain function, and have been widely applied to the field of the interior design today through designer＇ s unique understanding and constant design thinking, so that they are developed into the symbolic signs with the characteristics of traditional Chinese culture.
