Here 0 < ρ ∈ C(Ω) denotes the density, S is the Piola-Kirchhoff stress tensor which obeys the relation SF T = FS where F = I + ∇u is the deformation gradient. Divergence and transpose are taken with respect to the Euclidean metric | · |. The elasticity tensor C maps infinitesimal strain tensors E = (∇u+∇u )/2 to symmetric stress tensors CE. C represents the material properties on the elastic me...
Introduction: Proton magnetic resonance spectroscopy (MRS) is a well-known device for analyzing the biological fluids metabolically. Obtaining accurate and reliable information via MRS needs a homogeneous magnetic field in order to provide well-defined peaks and uniform water suppression. There are lots of reasons which can disturb the magnetic field homogeneity which can be corrected by a proc...
Extended Abstract Precocious puberty is the appearance of secondary sexual characteristics before 8 years old in girls and 9 years old in boys. Precocious puberty is divided into 3 groups of central, peripheral and normal variants. Central precocious puberty is accompanied by activation of hypothalamic-pituitary-gonadal axis which causes increase in secretion of GnRH, and in turn increase i...
In this work, we propose a novel method for deformable tensor-to-tensor registration of Diffusion Tensor Images. Our registration method models the distances in between the tensors with Geode-sic-Loxodromes and employs a version of Multi-Dimensional Scaling (MDS) algorithm to unfold the manifold described with this metric. Defining the same shape properties as tensors, the vector images obtaine...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
