La seguridad informática es un tema que nos ha dejado mucho de qué hablar en los últimos años. Los diferentes ataques masivos emitidos a los equipos cliente nos han dejado resultados bastante preocupantes. Fotos comprometedoras de grandes famosos filtradas en las redes de internet, la captura masiva de información para solicitar dinero, y programas espía en una gran cantidad de equipos son algunos ejemplos que nos ha dado la baja conciencia de los usuarios sobre los riesgos existentes al usar una computadora con sistema operativo Windows. Con base en esto, se propuso una investigación en la cual se vea reflejada el cómo entra un atacante a una computadora personal, cómo puede descifrar contraseñas a través de algoritmos de búsqueda, que tipo de control se puede obtener a través del ataque, que clase información se puede robar con el mismo y, de esa manera, plantear una metodología de prevención al usuario para hacer el acceso más difícil al atacante. Abstract —Computer security is a topic that has left us much to talk about in recent years. The different massive attacks issued to client computers have left us with quite worrying results. Engaging photos of big celebrities filtered on internet networks, the massive capture of information to request money, and spyware on a large number of computers are some examples that have given us the low awareness of users about the risks that exist when using a computer with Windows operating system. Based on this, an investigation was proposed in which it is reflected how an attacker enters a personal computer, how it can decipher passwords through search algorithms, what kind of control can be obtained through the attack, what class information can be stolen with it and, in that way, pose a prevention methodology to the user to make access more difficult to the attacker..

Aspects of Gandhi's Interpretation of Bhagavad Gita , 2024
Aspects of Gandhi's Interpretation of Bhagavad Gita, in: «Analele Universitatii din Craiova, Seria Filosofie», nr. 53 (1/2024), pp. 5–40. https://cis01.ucv.ro/analele_universitatii/filosofie/2024/Anale53_1.pdf The intent of our investigation is to expose and interpret aspects of Gandhi’s meditation on the Bhagavad Gita. One of the aims of Gandhi’s meditation on the Gita consists in searching for the foundations of the right moral thought and for the foundations of the right individual education. The revelation of the Gita is for the individual, among other things, a journey towards the discovery of himself and of his position in the reality; it is a journey towards the discovery of the possible developments of his own soul. The foundation of the right individual education has immediate social aspects: the right education proves to represent the very foundation of the right political action. In Gandhi’s view, the political doctrine and the political action ought to have as their own foundation the teachings of the Gita. The revelation of the Gita gives the individual the right moral education and the right moral foundation: it gives the knowledge of truth, of God, of reality, and of the individual nature. Through and thanks to the teachings of the Gita, the individual’s education finds the due foundation. The correct moral education is the basis of a right political and social order; it represents the basis for the dialogue between individuals and for the peaceful coexistence between individuals. The morally right order of the society is the consequence of the morally right order of the individual. Thus, the meditation on the Gita constitutes the foundation of the possibility of a right political strategy. Thanks to the education obtained through the meditation on the Gita, the individual is able to understand the right moral behaviour: this has an immediate effect on the structure and organisation of the whole society. In order that the society can be morally changed, the individual ought to develop his moral constitution in a right way. There may not be any right political programme without a previous individual right moral education. The analysis of the position of individuals within the reality and the investigation on the individual soul constitution enables the individual to reach an appropriate strategy for a right moral education. Since individuals consist of the three gunas — sattva, rajas, and tamas —, individuals are, as such, complex entities. Individuals are, moreover, dynamic entities: the development of the three gunas inside the individual soul, the relationships between the gunas in the soul, and the prevalence of a guna over the other gunas within the souls are not given once and for all; they depend on the education and on the life choices of the individuals. The prevalence of a guna over the other ones is due to the free decision of the individual; depending on how the individual decides to orientate his own life and depending on which parts of the soul the individual decides to cultivate, the soul of the individual will take a corresponding direction and will have a corresponding development. The responsibility for the development of one’s one life belongs to the individual. The corporeal dimension puts precise limits on the individual capacity of self-improvement within the corporeal life. Individuals ought to accept the limits due to their bodily dimension. At the same time, individuals ought to steadily try to improve themselves by promoting the virtues connected to sattva; the being-limited of individuals does not imply an absence of responsibility of the individuals as regards the moral value of their own actions. Individuals have the responsibility for being aware of their own constitution and for fighting against the limitations of their own condition. The fact that individuals are constitutively imperfect entails that individuals ought to educate themselves continuously; the individual ought to reach a moral foundation and ought to steadily pay attention to the stability of his own character. The main works analysed throughout our inquiry are Gandhi’s Discourses on the “Gita”, contained in The Collected Works of Mahatma Gandhi, XXXII (November 1926 – January 1927), pp. 94–376, and the work of Mahadev Desai, The Gospel of selfless action or The Gita according to Gandhi. Keywords: Gandhi, Bhagavad Gita, Atman, Moksha, Gita, Sattva, Tamas, Rajas, Desai, Mahabarata, Satyagraha.

The analysis of return series from financial markets is often based on the Peaks-over-threshold (POT) model. This model assumes independent and identically distributed observations and therefore a Poisson process is used to characterize the occurrence of extreme events. However, stylized facts such as clustered extremes and serial dependence typically violate the assumption of independence. In this paper we concentrate on an alternative approach to overcome these difficulties. We consider the stochastic intensity of the point process of exceedances over a threshold in the framework of irregularly spaced data. The main idea is to model the time between exceedances through an Autoregressive Conditional Duration (ACD) model, while the marks are still being modelled by generalized Pareto distributions. The main advantage of this approach is its capability to capture the short-term behaviour of extremes without involving an arbitrary stochastic volatility model or a prefiltration of the data, which certainly impacts the estimation. We make use of the proposed model to obtain an improved estimate for the Value at Risk. The model is then applied and illustrated to transactions data from Bayer AG, a blue chip stock from the German stock market index DAX.
