In this paper we try to clarify the confusions that lie around the widely used terms “analysis model” and “design model” in software engineering. In our experience, these confusions are the root of some difficulties that practitioners encounter in system modeling, and sometimes lead to bad engineering practices. Our approach consists of placing the duality of analysis and design within a three-...

Estimating maximum scour depth is normally required in order to determine the depth of  bridge piles. The present paper uses the SSIIM Software which considers flow and sediment equations in a three dimensional manner. The software models flow field around circular bridge pile by resolving Navier-Stokes three-dimensional equations and k-  method, and by temporary solution of flow field and cont...

Three-dimensional modeling from images, when carried out entirely by a human, can be time consuming and impractical for large-scale projects. On the other hand, full automation may be unachievable or not accurate enough for many applications such as culture heritage documentation. In addition, three-dimensional modeling from images, particularly fully automated methods, requires the extraction ...

Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...
