Development of Side Silicone Mold for Reducing Shape Error of Free-Form Concrete Panel

open access: yesBuildings, 2023
Errors that occur on the side shape of Free-form Concrete Panels (FCP) can cause errors in the FCP construction stage. Therefore, the error generated in FCPs must be reduced. Accordingly, side mold development and research are being carried out. However,

Optimization of the Panels Used in Free-Form Buildings and Its Impact on Building Cost

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The described study presents the context of the process of optimization curved panels and the direct impact on reducing high cost, especially in this type of free-form buildings. The main motivation for this study is the avoidance of the traditional style of design where it needs to produce expensive designs because free shapes ...

Fixed Point Algebras for Easy Quantum Groups [PDF]

open access: yes, 2016
Compact matrix quantum groups act naturally on Cuntz algebras. The first author isolated certain conditions under which the fixed point algebras under this action are Kirchberg algebras. Hence they are completely determined by their $K$-groups.

EFFECT OF MAGNETITE AND CHITOSAN-MAGNETITE ADDITION ON BACTERIAL LEVELS AND NH3-N (FREE-LIVING N2-FIXING BACTERIA CULTURE)

open access: yesJurnal Kimia Riset, 2023
Free-living N2-fixing bacteria are essential in the soil because they provide a source of nitrogen in the form of ammonium needed by plants to be used in building protein blocks.

Building Editable Free-form Models from Unstructured Point Clouds

open access: yesComputer-Aided Design and Applications, 2013
AbstractWe present a novel approach to reconstructing the surface of a 3D object using a point cloud of its surface scan. The objective is to obtain an editable CAD model that is manufacturable and describes accurately the structure and topology of the point cloud. The point cloud is sliced into cross sections. Each cross section is represented as a 2D
