Abstract : By using the knowledge of mathametical Origami &Kirigami ( Japanese art using principles of topology, operational research & statistics) An analytical study was done to make 3D boxes,in triangular,cubical,spherical,Polihedron etc.shape with maximum volumes and minimum raw material. Boxes of different shape may be made by twisting & folding. Pop up boxes, cartons& Mobius strips can also be made by the same method to minimize the cost of packing & wraping of manufactured products.

Abstract : Some early violins were reduced during their history to fit imposed morphological standards. We propose an objective photogrammetric approach to differentiate between a reduced and an unreduced instrument by examining 3D meshes, previously validated with a sub-millimetre accuracy through a comparison with CT scans. We show how quantitative and qualitative features can be automatically extracted from the meshes with geometrical, statistical and machine learning tools, allowing to successfully highlight differences between reduced and unreduced instruments.

Abstract : We discuss the randomized algorithm of AND-OR tree calculation. It is known that for any nontrivial balanced AND-OR tree, there is a unique randomized input (eigen-distribution) which achieves the distributional complexity. In contrast, the dual problem has the opposite result; the optimal randomized algorithm is not unique. We extend the study on randomized algorithms to unbalanced cases and see that uniqueness still fails in most of the cases.

Abstract : The accurate estimation of uncertain parameters in a mathematical model is still considered a laborious task. We propose a systematic methodology based on uncertainty and sensitivity analyses framework applied on a dynamic population balance model representing a crystallization process for the precise estimation of model parameters. For models involving many uncertain parameters, the proposed strategy can be adopted to rank parameters by their decreasing importance and then achieve precise estimation of the more significant parameters.
