Alain Badiou y la educación como proceso de subjetivación a través de verdades
2021
El siguiente texto presenta algunas tesis acerca de lo que puede aportar la obra del filósofo francés Alain Badiou en el debate acerca de la situación actual de la educación. Para ello se hará una lectura de su obra en clave propedéutica. La hipótesis de partida es que dicha obra puede leerse como un proyecto de recuperación de la filosofía entendida como una educación a través de verdades. Para ubicar esta tesis en el debate educativo contemporáneo se utilizará la teoría elaborada por Gert Biesta, quien ha construido en las últimas décadas un sistema de pensamiento que ofrece un marco teórico con el que fundamenta propuestas educativas alternativas a las tendencias individualistas, funcion…
Īpašuma apdrošināšanas analīze
2016
Bakalaura darbs „Īpašuma apdrošināšanas analīze” tiek izstrādāts, lai izpētītu īpašuma apdrošināšanas bruto parakstītās prēmijas un izmaksāto atlīdzību apmēru Latvijas apdrošināšanas tirgū, laika periodā no 2011. gada – 2015. gadam. Bakalaura darba mērķis ir uz īpašuma apdrošināšanas veiktās analīzes pamata, sniegt priekšlikumus īpašuma apdrošināšanas pilnveidošanai. Bakalaura darbs sastāv no trīs nodaļām un apakšnodaļām. Pirmā nodaļa sastāv no teorētiskām zināšanām par apdrošināšanas tirgus būtību, vēsturi, attīstību un apdrošināšanas pamatprincipiem. Otrā nodaļa sastāv no darba autores veiktās analīzes par īpašuma apdrošināšanas darbības rādītājiem, Latvijas apdrošināšanas tirgū, laika pe…
Elastic Recoil Detection Analysis
2008
In 1976, a Canadian group described in detail for the first time a new ion beam analytical method based on the elastic recoil of target nuclei collided with high-energy heavy incident ions. In this case, 25–40-MeV 35Cl impinged on a multilayer C or Cu (backing)/LiF or LiOH/Cu (30–150 nm)/LiF or LiOH and H, Li, O, and F recoiled atoms were detected. These exemplified the main characteristics of elastic recoil detection analysis (ERDA): its sensitivity to depth distribution and its ability to detect light elements in heavy substrates. In 1979, the use of megaelectronvolt energy 4He beams permitted the use of ERDA to be extended to depth profiling of hydrogen isotopes in the near-surface regio…
Elastic scattering cross sections for 6Li and 7Li scattering by aluminum, silicon and titanium below 12 MeV at angles of 140∘ and 170∘
1999
Abstract Elastic scattering cross sections for 6Li and 7Li scattering by natural aluminum, silicon and titanium have been measured in the energy range of 4–11 MeV. Scattering angles were 140∘ and 170∘ for 6Li and 140∘ for 7Li. The threshold energies above which Rutherford backscattering becomes invalid have been determined. Above this threshold the cross sections decrease rapidly, rendering backscattering analysis impractical. For 7Li scattering by Al and Si the observed threshold values were higher than for 6Li scattering. This behavior was reversed for scattering by Ti. The findings were systematic for both scattering angles. The present cross section and threshold data have been compared…
Layer-wise and equivalent single layer models for smart multilayered plates
2014
Layer-wise and equivalent single layer plate models for magneto-electro-elastic multiphysics laminates are presented in a unified framework. They are based on variable kinematics and quasi-static behavior of the electromagnetic fields. The electromagnetic state of each single layer is preliminary determined by solving the corresponding governing equations coupled with the proper interface continuity and external boundary conditions. By so doing, the electromagnetic state is condensed into the plate kinematics and the layer governing equations are inferred by the principle of virtual displacements. This approach identifies effective mechanical layers, which are kinematically equivalent to th…
An integrated structural health monitoring system based on electromechanical impedance and guided ultrasonic waves
2015
We propose a structural health monitoring (SHM) paradigm based on the simultaneous use of ultrasounds and electromechanical impedance (EMI) to monitor waveguides. Methods based on the propagation of guided ultrasonic waves (GUWs) are increasingly used in all those SHM applications that benefit from built-in transduction, moderately large inspection ranges, and high sensitivity to small flaws. Meantime, impedance-based SHM promises to adequately assess locally the structural integrity of simple waveguides and complex structures such as bolted connections. As both methods utilize piezoelectric transducers bonded or embedded to the structure of interest, this paper describes a unified SHM para…

La educación para la emancipación política a través del arte en el pensamiento de Alain Badiou
2011
[ES] En el siguiente texto trataremos de dar cuenta, de la mano del pensamiento del filósofo francés Alain Badiou, del papel que pueden jugar las prácticas artísticas en la formación para la emancipación política. En las siguientes líneas veremos cómo la relación entre arte y política se encuentra mediada por una actitud filosófica que reivindica que: 1) existen verdades universales y eternas, pero singulares e inmanentes al mundo en el que vivimos; 2) los términos "justicia" o "emancipación política" nombran los procedimientos de verdad en el seno de un orden político y social determinado; 3) para hacer efectivos dichos procedimientos es necesario participar en ellos; 4) el arte constituye…
A thermodynamically consistent CZM for low-cycle fatigue analysis
2018
A cohesive zone model for low-cycle fatigue analysis is developed in a consistent thermodynamic framework of elastic-plastic-damage mechanics with internal variable. A specific fatigue activation condition allows to model the material degradation related to the elastic-plastic cyclic loading conditions, with tractions levels lower than the damage activation condition. A moving endurance surface, in the classic framework of kinematic hardening, enables a pure elastic behavior without any fatigue degradation for low levels loading conditions.
