Permeable Walls

A mixture theory model is employed in a local description of the energy transfer in a duct with permeable wall which is simulated by considering two distinct flow regions, one consisting of a Newtonian incompressible fluid and the other represented by a binary (solid-fluid) mixture. Compatibility conditions at the interface (pure fluid-mixture) for momentum and energy transfer are considered. The simulations are carried out by using a finite difference approach with an upwind strategy for the convective term discretization.

Drowning is a global problem, and is among the main causes of death in the world, and the elderly are part of this new reality as a special group who also suffer submersion accidents. The aim of this study was to analyze deaths due to drowning in the elderly in the state of Paraíba from 2005 to 2015. This is a retrospective, descriptive study associated with spatial analysis of regions with a higher incidence of drowning in people aged 60 years or older in the state of Paraíba. Data were collected from the IML (Gemol and Numol) records from 2005 to 2015, totaling 80 cases of drowning. Sociodemographic characteristics such as age group, gender, spatiality and local description of the occurrence (rivers, dams, sea, waterfall, cacimbas, dams and domestic environments), care provider, file of the Legal Medical Institute of the Scientific Police, international code of diseases – ICD 10 (code W74), shift of occurrence. As results we located the region of Mari sector of the wild region of Paraíba – Açude Olho D’agua (Latitude 7.11º S and Longitude 35.2º ), was the place with the highest number of drownings, where dams/lakes (55%), male (91%), married (46%), aged between 60 and 69 years (60%), the local population made the first care (41%), 14h was of higher occurrence (11%), and on Sundays (29%). We can conclude that drowning occurs in several aquatic scenarios, and in this study occurred in fresh water, several factors were associated with drowning in the elderly, such as cognition deficits, polypharmaceuticals and physical limitations, such outcomes can help encourage protection policies for this group as well as family members guide in freshwater regions and accentuate care.

Feature extraction plays a key role in pattern recognition problems. The texture feature is an important feature which helps to describe an image with textural information. A new texture descriptor, the Local Symmetric Tetra Pattern (LSTP), is proposed in this work. This descriptor is developed for the local description of an image. It considers not only the surrounding eight neighbors, but also the eight pixels at the next level to describe the texture efficiently. For every pixel, the maximum edge value, the number of negative sign bits and the number of positive sign bits for each degree of symmetry are computed. Image classification is experimented using the Original Brodatz, Outex and Kylberg Texture Dataset v.1.0 databases. The investigation results are compared with existing method which shows promising achievement of the proposed techniques in terms of their evaluation measures. It is also found that the proposed texture descriptor is rotationally invariant.

Pseudo Inverse

Abstract Crisp and lattice-valued ambiguous representations of one continuous semilattice in another one are introduced and operation of taking pseudo-inverse of the above relations is defined. It is shown that continuous semilattices and their ambiguous representations, for which taking pseudo-inverse is involutive, form categories. Self-dualities and contravariant equivalences for these categories are obtained. Possible interpretations and applications to processing of imperfect information are discussed.

AbstractIt is assumed that the two-component spinor formalisms for curved spacetimes that are endowed with torsionful affine connexions can supply a local description of dark energy in terms of classical massive spin-one uncharged fields. The relevant wave functions are related to torsional affine potentials which bear invariance under the action of the generalized Weyl gauge group. Such potentials are thus taken to carry an observable character and emerge from contracted spin affinities whose patterns are chosen in a suitable way. New covariant calculational techniques are then developed towards deriving explicitly the wave equations that supposedly control the propagation in spacetime of the dark energy background. What immediately comes out of this derivation is a presumably natural display of interactions between the fields and both spin torsion and curvatures. The physical properties that may arise directly fromthe solutions to thewave equations are not brought out.
