right mind-minding: the practice and transmission of Zen and Tantric Buddhist method practices in the poemobjects of Dom Sylvester Houédard, 1960-1975
… the first substantial study of the work of Dom Sylvester Houédard. Although Houédard features in the recent studies on the contexts of the British concrete poetry movement, no previous research has focused exclusively on his work or foregrounded his spiritual vision as method. The aim of this …

Numerical solutions of matrix equations arising in model reduction of large-scale linear -time -invariant systems
… This PFADI method involves the solution of the Sylvester equation at each step, and its computational complexity depends on how efficiently the solution of the Sylvester equation is obtained. The final part of the thesis is devoted to the study of two techniques to solve the Sylvester equation. …

Controllability, Observability and Realizability
… time-varying systems, and first-order matrix Sylvester systems. Examples and sample computed calculations are provided for both uncontrolled and controlled systems. We also develop a new method for computing the approximate values of matrix exponentials, and use this to estimate solutions to …

Cascade analysis and synthesis of transfer functions of infinite dimensional linear systems
… interpretation to the solution of a linear Sylvester equation involving unbounded operator coefficients. As an application, some preliminary work is presented toward obtaining a state space solution of the sensitivity minimization problem for a pure delay plant.

Reduced Order Methods for Large Scale Riccati Equations
… methods to Chandrasekhar equations, Lyapunov/Sylvester equations, or combinations of these equations. Our numerical examples illustrate improvements in computational time up to several orders of magnitude over standard tools (when these tools can be used). We also present examples that cannot …

Organic Angels: Innocence, Conversion, and Consumption in the Antebellum American Novel
… surprisingly diverse range of authors and works—Sylvester Judd's Margaret, Maria Cummins' The Lamplighter, Hawthorne's The Marble Faun, Melville's Pierre, Stowe's Uncle Tom's Cabin, and Harriet Wilson's Our Nig. At once a remarkably flexible and legibly constraining trope, the organic angel …

Homotopy methods for solving the optimal projection equations for the reduced order model problem
… projection matrix that involves solving a set of Sylvester equations is given. Another class of methods considers the equations in a modified form, using a decomposition of the pseudogramians based on a contragredient transformation. Some freedom is left in making an exact match between the number …

"""Lines of Spiritual Motion"": The Realization of American Catholic Fiction, 1845-1965"
… Dorothy Day, Hilary Leighton Barth, Harry Sylvester, and Flannery O’Connor—who provided a fertile ground for American Catholics to transition from a conflicted relation to dominant American culture to fuller participation in it, marked by the move from urban Catholic ghettoes at the turn of …

Musical Notation and Liturgical Books in Late Carolingian Nonantola
… of the northern Italian Benedictine abbey of St Sylvester in Nonantola has hitherto been neglected by most scholarship on early music scripts, mainly because of the paucity of surviving music manuscripts and their limited geographical diffusion. A new study was needed in order to develop a full …

How to remember thee?: problems of memorialization in english writing, 1558-1625
… 1612 and argues that poets George Wither, Joshua Sylvester, and Henry Peacham, and the preacher Daniel Price use biblical figurae of kings David and Josiah to represent Henry as a militant Protestant saint. I also show that John Donne uses figural interpretation in his elegy to advance an agenda …

Inventing the Charles River Basin : urban images and civic discourse in Boston, 1844-1994
… in their plan for a metropolitan park system, Sylvester Baxter and Charles Eliot advocated the "scientific selection" of public open space to establish a framework for the growth of the region. At the end of the twentieth century, Boston set out to build the largest highway project in the …

Dimension Reduction in Structured Dynamical Systems: Optimal-𝓗<sub>2</sub> Approximation, Data-Driven Balancing, and Real-Time Monitoring
… contributions of this portion, we establish the Sylvester equation-based (Wilson) and interpolation-based (Meier-Luenberger) $mathcal{H}_2$-optimality frameworks for this class of systems. These frameworks are based on two independent sets of first-order necessary conditions for optimality. We …

Umbral Calculus A Different Mathematical Language
… the methods introduced by the operationalists (Sylvester, Boole, Glaisher, Crofton and Blizard) of the second half of the XIX century. The method has opened new avenues to deal with rational, trascendental and higher order trascendental functions, by the use of the same operational forms. The …
