La placa grabada de Balma Guilanyà (Prepirineo de Lleida) y las manifestaciones artísticas del Mesolítico de la Península Ibérica
2011
A carved rock with geometric and/or abstract signs discovered at the Balma Guilanyà site has made possible the analysis of the artistic patterns developed after the end of the Upper Palaeolithic in the Iberian Mediterranean region. Archaeo-stratigraphic, chronometric and chrono-cultural attributes link this finding to the Mesolithic, probably during the tenth millennium cal BP. Graphic analysis and the comparison with different kinds of representations from this same area allows the evaluation of the problematic that surrounds the characterization of West Mediterranean Mesolithic art.
Il concetto di libertà nella ricezione italiana della Geschichte der Kunst
2020
L’influenza che gli scritti winckelmanniani esercitano sull’estetica italiana risale, com’è noto, al periodo della sua permanenza e attività a Roma al servizio del Papa. Tuttavia si fa più netta e riconoscibile all’atto della prima traduzione italiana della Storia delle arti del disegno (Geschichte der Kunst) nel 1779 e si intensifica, assumendo connotati non solamente estetologici, nella prima metà dell’Ottocento.
Diagnostics of stator winding failures in wind turbine pitch motors using Vold-Kalman filter
2019
Pitch systems are among the most failure-prone components in wind turbines. Winding failures in pitch motors are common due to high start-up loads and poor ventilation. This article presents a diagnostics scheme that can detect the stator winding failures in the pitch motors under time-varying speed and load conditions. The proposed approach based on three-phase motor currents can be directly integrated into the motor drive and can be used for induction as well as permanent magnet synchronous machines. The extended Park's vector calculated on the motor currents is order tracked based on the supply frequency from the drive using Vold-Kalman filter. The approach is shown to be robust under ar…
Wind Shear On-Line Identification for Unmanned Aerial Systems
2014
An algorithm to perform the on line identification of the wind shear components suitable for the UAS characteristics has been implemented. The mathematical model of aircraft and wind shear in the augmented state space has been built without any restrictive assumption on the dynamic of wind shear. Due to the severe accelerations on the aircraft induced by the strong velocity variation typical of wind shear, the wind shear effects have been modeled as external forces and moments applied on the aircraft. The identification problem addressed in this work has been solved by using the Filter error method approach. An Extended Kalman Filter has been developed to propagate state. It has been tuned …
Using Hypervisors to Overcome Structured Exception Handler Attacks
2019
Microsoft windows is a family of client and server operating systems that needs no introduction. Microsoft windows operating system family has a feature to handle exceptions by storing in the stack the address of an exception handler. This feature of Microsoft Windows operating system family is called SEH (Structured exception handlers). When using SEH the exception handler address is specifically located on the stack like the function return address. When an exception occurs the address acts as a trampoline and the EIP jumps to the SEH address. By overwriting the stack one can create a unique type of return oriented programming (ROP) exploit that force the instruction pointer to jump to a …

Itsetuntemus, ekspressivismi ja Wittgenstein
2017
Tämä artikkeli esittelee ekspressivististä itsetuntemuksen (self-knowledge) teoriaa erityyppisten itsetuntemuksen teorioiden kontekstissa. Artikkelin viimekätinen tavoite on arvioida erityisesti ekspressivistisen teorian suhdetta Wittgensteinin mielenfilosofiaan, joka usein mainitaan teorian lähteenä, ja tarkastella teorian kehitystarpeita ja -mahdollisuuksia muiden itsetuntemuksen teorioiden valossa. Osassa 1 esitetään eräitä käsitteellisiä selvennyksiä. Osa 2 käsittelee itsetuntemuksen (omia mentaalisia tiloja koskevan tiedon) oletettuja filosofisesti kiinnostavia erityispiirteitä, joiden ymmärtäminen on itsetuntemuksen teorioiden arvioimisen kannalta olennaista. Osa 3 esittää itsetuntemu…
Wittgenstein, constructor de modelos
2013
Wittgenstein siempre practicó la filosofía como una actividad esclarecedora de las condiciones conceptuales del significado lingüístico. En la primera parte del artículo se trata de probar el papel relevante que Wittgenstein dio al uso de modelos como método de análisis del funcionamiento del lenguaje. Asimismo, en la parte final se intenta mostrar la dimensión ética y la significación estética que Wittgenstein atribuyó a su labor filosófica de aclaración. For Wittgenstein, the philosophical working was an enlightening tool in order to disclose the conceptual conditions of the linguistic meaning. The aim of the first part of the paper is to show the relevant role that Wittgenstein gave to m…
