Jacques-Antoine-Hippolyte, Comte De Guibert: Father of the Grande Armée

Description: Jacques-Antoine-Hippolyte, comte de Guibert (1743-1790) dedicated his life and career to creating a new doctrine for the French army. Little about this doctrine was revolutionary. Indeed, Guibert openly decried the anarchy of popular participation in government and looked askance at the early days of the Revolution. Rather, Guibert’s doctrine marked the culmination of an evolutionary process that commenced decades before his time and reached fruition in the Réglement of 1791, which remained … more

Uncertainty Evaluation in Large-scale Dynamical Systems: Theory and Applications

Description: Significant research efforts have been devoted to large-scale dynamical systems, with the aim of understanding their complicated behaviors and managing their responses in real-time. One pivotal technological obstacle in this process is the existence of uncertainty. Although many of these large-scale dynamical systems function well in the design stage, they may easily fail when operating in realistic environment, where environmental uncertainties modulate system dynamics and complicate real-time… more

Condition-dependent Hilbert Spaces for Steepest Descent and Application to the Tricomi Equation

Description: A steepest descent method is constructed for the general setting of a linear differential equation paired with uniqueness-inducing conditions which might yield a generally overdetermined system. The method differs from traditional steepest descent methods by considering the conditions when defining the corresponding Sobolev space. The descent method converges to the unique solution to the differential equation so that change in condition values is minimal. The system has a solution if and only … more

An Examination of Text Reflection and Imagery in Zoltán Gárdonyi’s Fünf Lieder Nach Gedichten Von Rainer Maria Rilke

Description: Zoltán Gárdonyi is described as having exemplified “the continuation of the Liszt tradition” in his music; however, since for so much of his compositional life he was forbidden to publish by the Communist government in Hungary due to his connection to the Christian church, he has been largely forgotten. Shortly after the composer’s death in 1986, Gárdonyi’s son, Zsolt (b.1946) began publishing his father’s music in addition to his own. However, the elder Gárdonyi’s works are still not widely kn… more
