existence and continuity
… this thesis attempts to amplify the co-existence of overlaying fragments of construction. Interventions with extant artifacts are another layer compounded toward a continuing history of building. This investigation is a search for an architecture with a presence of permanence and …

Existence of God: An Examination of the Cosmological Arguments as Proof of the Existence of God
… of several types of arguments which support the existence of god on the basis that god is the best explanation of the universe. Thomas Aquinas presents three ways which support the existence of an unchanging mover, a first efficient cause and a necessary being. (Aquinas, 25) Bruce Reichenbach …

Periodic existence theorems in optimal control
This paper considers existence theorems for the optimal control problem min (x,u) lo(x(0),x(T))+ ʃT0 fo(t,x(t),x(t),u(t)) subject to: x(t) = f(t ,x(t),u(t)) (x(0), x(T)) ∈ B (x(t),u(t)) ∈ F x ∈ An[0, T] u ∈ Lm[0, T] Using the results of R.T. Rockafellar this problem is reformulated into a problem …

Existence and stability of stellardynamic models
We examine existence and stability of stationary solutions to the Vlasov-Poisson system. This system is used in stellardynmaics to describe the evolution of galaxies where collissions are neglected and the evolution is determined by the self-consistent gravitational field which is created by the …

A Phenomenological Analysis of Meaningful Existence
Although meaning in life has been investigated widely through disciplines including philosophy and psychology, it has not been rigorously pursued phenomenologically. In taking a phenomenological approach, my thesis is an attempt to illuminate the experiential character of meaning in life. To engage …

Differentiability, Continuity, and Existence of Limits
… we first demonstrate in various aspects the existence of everywhere continuous nowhere differentiable functions. We then address the question: could there exist a function defined on R that has a limit at each point of R, but fails to be continuous at any point? We show that the answer to …

Existence and Importance of Online Interaction
This research explored the existence and importance of interaction in online courses as perceived by online learners and instructors. The study was based on data from online students and instructors in the fall 2002 semester at Mid-Atlantic Community College(1). Two web-based surveys were used to …

Vibrating Existence: Early Cinema and Cognitive Creativity
This thesis collects together technical, historical and neurological evidence to examine how our perceptual and cognitive experience of cinema has changed diachronically and especially as a result of the transition from analogue to digital cinema projection. The slow arrival but sudden dominance of …

Three Existence Problems in Extremal Graph Theory
Proving the existence or nonexistence of structures with specified properties is the impetus for many classical results in discrete mathematics. In this thesis we take this approach to three different structural questions rooted in extremal graph theory. When studying graph representations, we seek …

Analog-digital co-existence in 3D-IC
Ubiquitous mobile communication creates an increasing demand for high data rates, complex modulation schemes and low power design. The cost and performance benefits of conventional lithographic scaling are diminishing as process cost increases exponentially. 3D integration has the potential to keep …

Existence of competitive equilibria in combinatorial auctions
… first step in auction design is to establish its existence. Recent work by Baldwin and Klemperer (2012) has proved that the "demand type" of valuations being "unimodular" is a necessary and sufficient condition for the existence of a competitive equilibrium, but under the general setting where …

Existence de solutions périodiques de l'équation de Josephson
Ce mémoire porte sur l’étude de l’existence des solutions périodiques de l’équation de Josephson. La première partie est consacrée au rappel des notions de base de l’espace L[exposant]2[indice]T et de quelques théorèmes fondamentaux sur les points fixes. Par la suite, après avoir défini le cadre d …

Disconnect: The Persistence of Isolation in Contemporary Existence
This paper discusses a series of paintings exploring the effects of isolation in the human experience. The focus concerns both a specifically twenty-first century manner and a more universal framework. Drawing inspiration from her past experiences, the author also references a number of artists …

Gamemania: What Makes A Virtual Existence So Seductive?
While much has been written and said about consumer addiction to digital technology in the media, little academic research has actually been conducted on post-purchase technology consumption and its negative impact on consumer welfare. This dissertation takes an important step in this direction by …
