On shape optimization of conduits with incompressible flow [PDF]

open access: yesApplied and Computational Mechanics, 2007
In this paper we present an optimal flow problem in the context of internal laminar incompressible flows of Newtonian liquid. The flow optimization problem is introduced in variational form of the stationary Navier-Stokes equations.

Microdroplet oscillations during optical pulling

open access: yes, 2011
It was recently shown theoretically that it is possible to pull a spherical dielectric body towards the source of a laser beam [Nature Photonics {\bf 5}, 531 (2011)], a result with immediate consequences to optical manipulation of small droplets. Optical

On the Aliphatic versus Aromatic Content of the Carriers of the "Unidentified" Infrared Emission Features

open access: yes, 2016
Although it is generally accepted that the so-called "unidentified" infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micrometer are characteristic of the stretching and bending vibrations of aromatic hydrocarbon materials, the exact ...

RECONSTRUÇÃO 3D DE OSSOS A PARTIR DE IMAGENS DE RAIO-X

open access: yesColloquium Exactarum, 2013
This paper presents a method for building a three dimensional model of the lower leg bone (tibia) from a human, from X-ray images. The methodology adopted to obtain the 3D object is deforming the model until it corresponds to X-ray images (front and ...

A nth-order shear deformation theory for composite laminates in cylindrical bending

open access: yesCurved and Layered Structures, 2015
The present study investigates whether an nthorder shear deformation theory is applicable for the composite laminates in cylindrical bending. The theory satisfies the traction free conditions at top and bottom surfaces of the plate and does not require ...

Recursively minimally-deformed oscillators

open access: yes, 1995
A recursive deformation of the boson commutation relation is introduced. Each step consists of a minimal deformation of a commutator $[a,\ad]=f_k(\cdots;\no)$ into $[a,\ad]_{q_{k+1}}=f_k(\cdots;\no)$, where $\cdots$ stands for the set of deformation ...

An integrable Lorentz-breaking deformation of two-dimensional CFTs

open access: yesSciPost Physics, 2018
It has been recently shown that the deformation of an arbitrary two-dimensional conformal field theory by the composite irrelevant operator $T \bar T$, built from the components of the stress tensor, is solvable; in particular, the finite-size ...

Interpolations of Bargmann Type Measures

open access: yesDemonstratio Mathematica, 2016
In this paper, we shall discuss Bargmann type measures on C for several classes of probability measures on R. The unified interpolation expressions include not only the classical Bargmann measure and its q-deformation, but also their t-deformations and ...

Aerodynamic optimization of multi-stage axial turbine based on pre-screening strategy and directly manipulated free-form deformation

open access: yesCase Studies in Thermal Engineering
To address the challenges of multiple design variables, long evaluation times, and poor global search capability of traditional surrogate-assisted algorithms that rely on the complete substitution of accurate function evaluations in the turbine ...

Feature-Based Modeling of Subject-Specific Lower Limb Skeletons from Medical Images

open access: yesBiomechanics
Background/Objectives: In recent years, 3D shape models of the human body have been used for various purposes. In principle, CT and MRI tomographic images are necessary to create such models.
