Machine learning is an application of artificial intelligence that is able to automatically learn and improve from experience without being explicitly programmed. The primary assumption for most of the machine learning algorithms is that the training set (source domain) and the test set (target domain) follow from the same probability distribution. However, in most of the real-world application...
Ranges of validity for the continuum-beam model, the length-scale effects and continuum assumptions are analyzed in the framework of scaling analysis of NT structure. Two coupled criteria for the applicability of the continuum model are presented. Scaling analysis of NT buckling and geometric parameters (e.g., diameter and length) is carried out to determine the key non-dimensional parameters t...
An efficient finite difference model of blood flow through the coronary vessels is developed and applied to a geometric model of the largest six generations of the coronary arterial network. By constraining the form of the velocity profile across the vessel radius, the three-dimensional Navier–Stokes equations are reduced to one-dimensional equations governing conservation of mass and momentum....
Geometric constraint solving has applications in a wide variety of elds, such as mechanical engineering, chemical molecular conformation, geometric theorem proving, and surveying. The problem consists of a given set of geometric elements and a description of geometric constraints between the elements. The goal is to nd all placements of the geometric entities which satisfy the given constraints...
the purpose of this study is to design a three-stage axial compressor with identical pressure ratio which makes an adequate pressure ratio and efficiency in design point conditions with rotational velocity of 38000rpm and mass flow rate of 3.2kg/s. first of all, considering some restrictions such as dehaller number more than 0.7 in all sections of the stator and the rotor, and relative mach num...
On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional uniication, a geometric model is presented that associates with each quantum phase an element of a transformation group.
The relationship between tolerances of statically measured geometric parameters and the aerodynamic performance of a sample of manufactured airfoils is investigated in this thesis. The objective is to determine which geometric parameters are the best discriminators of performance, and how these best discriminators are affected by changes in design methodology, manufacturing precision, and desir...
This paper introduces a prototype system, SketchingMetal, that enables individuals with no manufacturing expertise to quickly design a restricted domain of precise, manufacturable, three-dimensional geometric models. Unlike previous systems that generate plastic prototypes from more general geometric models, models created with SketchingMetal can be manufactured automatically as functional mach...
Due to the importance of determining the pelastic manner of thin wall shells against the explosive loading, up to the maximum process of deformation, examining the manner of this kind of structures is on the agenda.concidering repeated reaction of explosive shock wave from two ends and the walls of the structure, pressure distribution derived from explosion of explosive in closed shells, is too...
On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional unification, a geometric model is presented that associates with each quantum phase an element of a transformation group.
