On Shape and Material Optimization of Isotropic Bodies

open access: yesEngineering Transactions, 2017
This paper deals with the free material design and its two constrained versions constructed by imposing isotropy with (i) independent bulk and shear moduli, and (ii) fixed Poisson’s ratio. In the latter case, the Young modulus is the only design variable.

3D Reconstruction of a Single Bubble in Transparent Media Using Three Orthographic Digital Images

open access: yesApplied Sciences, 2020
This work proposed a method to reconstruct the 3D bubble shape in a transparent medium utilizing the three orthographic digital images. The bubble was divided into several ellipse slices.

Optimum Designs in Regression Problems [PDF]

open access: yesThe Annals of Mathematical Statistics, 1959
Although regression problems have been considered by workers in all sciences for many years, until recently relatively little attention has been paid to the optimum design of experiments in such problems. At what values of the independent variable should one take observations, and in what proportions?

Radiation Effect on Constructal Design Analysis of a T-Y-Shaped Assembly of Fins

open access: yesJournal of Thermal Science and Technology, 2012
In the actual design circumstances, the radiation effect on the cooling performance of the extended surfaces must be taken into consideration. The central goal of this paper is to design the constructal architecture of a T-Y shaped assembly of fins by ...

Optimum Experimental Designs

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1959
Summary After some introductory remarks, we discuss certain basic considerations such as the nonoptimality of the classical symmetric (balanced) designs for hypothesis testing, the optimality of designs invariant under an appropriate group of transformations, etc. In section 3 we discuss complete classes of designs, while in section 4 we

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
