1. Using the Interval Metric for Modeling Entities Geometrics in ℝ2 - Case Study Interval Circumference
ABSTRACT The study of some distances provide science a way to separate two entities. It has applications in various fields such as remote sensing, data mining, pattern recognition and multivariate data analysis and others. If the distance is a Hausdorff metric, the guarantee is that all individuals are available. With the use of the distance of Trindade et a

2. MODELING AND SIMULATION OF A VACUUM MEMBRANE DISTILLATION PLANT COUPLED WITH SOLAR ENERGY AND USING HELICAL HOLLOW FIBERS
Abstract This paper investigates the effect of operating conditions such as coil pitch, fiber diameter, distance between fiber and absorber internal wall and absorber diameter for a vacuum membrane installation coupled with solar energy and using helically coiled fiber to maximize the permeate flow rate. The model is based on a system of equations composed o

4. The Effects of Scalloping Width and Position on Jet Mixing of Lobed Nozzles
ABSTRACT: A series of geometric models of lobed nozzles with a central plug was created by different scalloping positions and widths. The shapes of lower and upper edges, cutting depth were kept unchanged. In this study, by the use of numerical simulation, the effects of scalloped width and position on the performance of jet mixing in the pumping condition w

5. Mechanical influence of thread pitch on orthodontic mini-implant stability
The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1(30oX 0.6 mm) and G2(45o X 0.8 mm), and inserted into artificial bone of different densities: D1 (0.32 g/cm3) and D

6. Nonlinear mathematical modeling of vibrating motion of nanomechanical cantilever active probe
Nonlinear vibration response of nanomechanical cantilever (NMC) active probes in atomic force microscope (AFM) application has been studied in the amplitude mode. Piezoelectric layer is placed piecewise and as an actuator on NMC. Continuous beam model has been chosen for analysis with regard to the geometric discontinuities of piezoelectric layer attachment

7. The Wits appraisal among a Nigerian sub-population: an assessment of dental base geometric factors
The Wits appraisal is a common linear cephalometric analytic tool established by Jacobson. It has been reported to be superior to angular cephalometric measures as it is not dependent on pericranial structures and their variations both during growth and orthodontic treatment. AIM: To obtain reference values for the Wits appraisal among Nigerians and assess t

8. A stress-displacement solution for a pressure tunnel with impermeable liner in elastic porous media
Considering the effects of the changes of the pore water pressure around the opening, the construction sequence of the tunnel and the interaction between the liner and the surrounding geomaterial on the mechanical response of the tunnel and in conjunction with the analyses of the continuity and boundary conditions for the stress and displacement and hydrauli

9. Geometria e simetrias do emaranhamento
In the present work we present a geometric method to identify and measure the degree of entanglement of a two-qubit state. It is based on writing a map of the system state, from a non-unitary transformation. By introducing new parameters for such 4X4 matrix, the product of eigenvalues, two by two, acquire the form of squared 4D distances, having a Minkowski

10. Allometry and ontogeny in Callibia diana Stål (Mantodea: Acanthopidae)
The life-cycle of Callibia diana Stål is described and linear and geometric morphometrics are used for studying allometrics and shape changes throughout this neotropical mantid species' life-cycle. Significant changes were expected in the allometry and shape of the raptorial leg and abdomen, given the importance of hunting and reproduction. The allometric s

11. Sobre o acoplamento fluido-casca utilizando o método dos elementos finitos / On fluid-shell coupling using the finite element method
This work consists of the development of computational tools for nonlinear geometric fluid-shell interaction analysis using the Finite Element Method (FEM). The fluid solver is explicit and its time integration based on characteristics. The computational code is able to simulate the Navier-Stokes equations for compressible flows written in the Eulerian descr

12. Análise da variação longitudinal do esqueleto axial em Serpentes (Squamata) empregando ferramentas de morfometria geométrica / Analysis of the longitudinal variation in the axial skeleton of Serpentes (Squamata) using geometric morphometrics techniques
As cobras são um grupo de vertebrados extremamente bem sucedido. Apesar da aparente simplicidade, elas conseguiram ocupar uma grande diversidade de habitats. O esqueleto axial das serpentes apresenta relação com vários aspectos da vida que puderam ter tido influência direta em seu sucesso evolutivo. Além disso, a forma dos elementos vertebrais possui v
