Broadband space-variant Fresnel processor
2002
We present a radically new class of optical setup working with white-light illumination, namely, a chromatically compensated processor operating in the Fresnel domain. The optical configuration is a hybrid (diffractive-refractive) three-lens system that exhibits an intermediate achromatic Fresnel plane and an output image plane without chromatic distortion. As a first application of this optical arrangement we develop a parallel space-variant color pattern-recognition experiment with white light.
BEF Analogy for Concrete Box Girder Analysis of Bridges
2010
<p>Box girder, due to its high torsional stiffness, is very appropriate for railway and highway long- medium span bridges. This type of cross section, subjected to transversely non-uniform loads, present warping and distortion phenomena. Accurate but time-consuming numerical procedures are available for determination of further strains and stresses caused by cross-section deformation. In this paper warping and distortion of box girders is evaluated through BEF analogy, by writing a 4th order differential equation. The problem is solved for practical cases of box girders by considering internal diaphragms stiffness. Graphs are supplied to designers and main design parameters affecting …
Tortuous flow in porous media
1996
The concept of tortuosity of fluid flow in porous media is discussed. A lattice-gas cellular automaton method is applied to solve the flow of a Newtonian uncompressible fluid in a two-dimensional porous substance constructed by randomly placed rectangles of equal size and with unrestricted overlap. A clear correlation between the average tortuosity of the flow paths and the porosity of the substance has been found. \textcopyright{} 1996 The American Physical Society.
Permeability and effective porosity of porous media
1997
The concept of permeability of porous media is discussed, and a modification of Kozeny’s permeability equation to include the effect of effective porosity is introduced. An analytical expression for the specific surface area of a system constructed of randomly placed identical obstacles with unrestricted overlap is derived, and a lattice-gas cellular automaton method is then used to simulate the dependence on porosity of permeability, tortuosity, and effective porosity for a flow of Newtonian uncompressible fluid in this two-dimensional porous substance. The simulated permeabilities can well be explained by the concept of effective porosity, and the exact form of the specific surface area. …
Determination of projection geometry from quantitative assessment of the distortion of spherical references in single-view projection radiography
2004
A method is introduced, inferring the three-dimensional (3-D) location from the 2-D radiographic shadow of an opaque spherical reference body of known radius by considering its elliptical distortion, the 2-D shadow location and a known source-to-receptor distance. Three noncollinear spheres fixed to a rigid object constitute all possible degrees of freedom, i.e., the entire 3-D imaging geometry. The method may be used (a) to determine the 3-D imaging geometry from a single 2-D view and (b) to correct for foreshortening of object distances coplanar with the plane defined by the sphere triplet. Apart from the mathematical background the article describes a small feasibility experiment, perfor…
Plaģiāts zinātniskajā darbā kā autortiesību aizskārums.
2017
Plaģiātisms – radošo darbu slimība, pret kuru zāles nav atrastas. Jau kopš senajiem romiešu laikiem ir pazīstami plaģiāti. Attīstoties tehnoloģijām palielinās arī pieejamais informācijas apjoms un plaģiātu uzbūves sarežģītība. Darba mērķis ir izpētīt plaģiātisma problemātiku un sniegt ieteikumus praktiskām darbībām plaģiātisma apkarošanai, kā arī normatīvo aktu pilnveidojumus. Darbs galvenokārt ir vērsts uz studentu plaģiātismu. Mērķa sasniegšanai darba autors izmanto dažādu autoru avotus par plaģiātismu, aplūko normatīvo aktu regulējumu gan Latvijā, gan ārvalstīs, tiek apskatīts arī tiesu praksē definētais plaģiātisms, kā arī citus avotus. Pirmajā nodaļā autors apskata plaģiātisma vēsturi …

Género y tortura. Simone de Beauvoir y Gisèle Halimi ante el caso de Djamila Boupacha
2021
La primera denuncia de violencia sexual como práctica de tortura en la guerra de Argelia se debe a Djamila Boupacha. Su causa fue defendida ante los tribunales argelinos y franceses por la abogada feminista, Gisèle Halimi, y tuvo una gran repercusión pública gracias al apoyo de Simone de Beauvoir y a la movilización de un comité conformado sobre todo por mujeres, en el intento de dar relevancia política y jurídica a un asunto destinado a permanecer oculto. El trabajo valora el enfoque anticolonial y antipatriarcal con que se afrontó el caso, analiza todo el proceso judicial y llama la atención sobre aquellos elementos que prefiguran la evolución del derecho hacia una justicia de género.
Nuove stazioni italiane di Tortula freibergii
2010
Two new localities of Tortula freibergii Dix. & Loeske, a moss threatened in Europe, are reported. They are localized in North-western Sicily, one inside Natural Reserve of “Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere e Gorgo del Drago” and the other near to the Archaeological area of Segesta. Both populations live on inland sections of waterways.
