A numerical lifting line method, coupled with a numerical blade element method, is presented as a low computational cost approach to modeling slipstream effects on a finite wing. This method uses a 3D vortex lifting law along with known 2D airfoil data to predict the lift distribution across a wing in the presence of a propeller slipstream. The results are of significant importance in the devel...

This article describes the construction of a building with four aboveground floors and one underground floor as part ongoing development Warsaw’s city center. A 3D numerical model was developed to reflect spatial structural solutions new based on design documentation regard outcomes geotechnical tests, actual phases work completed, results geodetic measurements carried out in individual impleme...

In this study, 3D detailed numerical modeling was performed to evaluate the performance of an artificial recharge–water intake system installed secure agricultural water in drought areas. Using a irregular finite element grid, conceptual model constructed that reflected actual scale study area and considered characteristics saturated–unsaturated aquifers. The optimal design factors for recharge...

We introduce an algebraic modeling language, named ROME, for a class of robust optimizationproblems. ROME serves as an intermediate layer between the modeler and optimization solverengines, allowing modelers to express robust optimization problems in a mathematically meaningfulway. In this paper, we highlight key features of ROME which expediates the modeling and subsequentnumer...

The self-assembly of biological molecules and systems is a common phenomenon in nature. Linear chains of protein molecules fold into functional 3D structures in one example of biological self-assembly (1). Computational scientist Daan Frenkel at the University of Cambridge seeks to explore how self-assembly might be applied to fields such as nanoscience, manufacturing, and robotics, among other...

This paper presents an overview of the current state of the art in image fusion, with an emphasis on the emergence of new techniques, often issued from other domains like arti cial intelligence and uncertainty modeling. We address the two following points: rstly the aim of data fusion and its speci city when image information has to be combined, with emphasis on the respective roles of numerica...

To support 3D architectural modeling, geometric constraints are introduced. Explicit and implicit geometric relations between building elements can be expressed by the designer and imposed on the 3D geometry of the design. A complete set of constraint types is defined. Constraints are satisfied through Numerical Methods to achieve that the model responds to the designers’ actions in a user-intu...
