Uma formalização da mecânica analítica dos sistemas de corpos rígidos
The Lagrange's equations for systems of rigid bodies are obtained directly from the laws of motion for a rigid body, without the preliminary study of systems with a finite number of parti eles. ln doing so, the role of the evolution law for the angular momentum is made clear for the development of …

Adaptive Finite Element Methods for Rigid Particulate Flow Problems
Subject of this work is the numerical simulation of the motion of rigid particles in an incompressible viscous or viscoelastic fluid. What makes this task especially challenging is the fact that two different physical models are coupled: The fluid motion is described by a system of partial …

Numerical Modelling of Ball Bearing Stiffness to Predict Contact Stress Caused by Vibration Induced Gapping
The ball bearings that form part of mechanisms in space applications are subjected to vibrations. The result of these vibrations is gapping between the rings of the bearing. This gap allows collisions of the ball with the races, which produce high contact stresses. These high stresses can cause …

Marx and modern value theory
… theory is standardly interpreted as a theory of price: qualitatively, as a kind )f materialist sociology, concerned to show how money, markets and prices, in a developed form, are the mere reflux of a particular mode of production, i. e. capitalism; and quantitatively, how the configuration of …

Brownian particles interacting with a Newtonian Barrier: Skorohod maps and their use in solving a PDE with free boundary, strong approximation, and hydrodynamic limits.
In this thesis, we pioneer the use of Skorohod maps in establishing the hydrodynamic behavior of an interacting particle system. This technique has the benefit of using stochastic methods to show both existence and uniqueness of the resulting PDE with free boundary condition. In 2001, Frank Knight …

Fluid mechanics of liquid drops and thin-films
… polymers, gels, which are governed by physical laws of motion. The present dissertation is a detailed theoretical, experimental, and numerical study of the complex phenomenon exhibited by liquid drops and liquid thin-films. Studying these systems is important both from fundamental and applied …

Motion in music: a study of movement and time through musical interpretation
'Motion in Music' is a study of movement and time through musical interpretation. It looks at ways in which motion, both physical and conceptual, is featured in the musical performance and it is, therefore, written with the performance of music in mind. As such, it provides us with a fresh approach …

Real root counting for parametric polynomial systems and applications.
… systems appear in many different fields of study. Many important problems can be reduced to solving systems of polynomial equations and usually the coefficients involve parameters. This thesis is devoted to finding practical ways to solve such problems from two fields, the studies of …

Object lessons: sensory science education 1830-1870
… children could listen to fairy-tales of wondrous forces and minuscule creatures; from the toy-chest, they could play with hoops and tops that demonstrated the laws of motion; at the table, they could taste and smell the chemical constituents of a cup of tea; in the garden, they could …

Louis de la Forge on Mind-Body Interaction and the Case Against Occasionalism
… to the Cartesian philosophy requires a defense of dualism as well as mind-body union and interaction, all the while keeping to some form of the causal likeness principle. Each of these positions are ones that Descartes maintained throughout his writings. Yet, successors and scholars alike have …

An Optimization of Thermodynamic Efficiency vs. Capacity for Communications Systems
This work provides a fundamental view of the mechanisms which affect the power efficiency of communications processes along with a method for efficiency enhancement. Shannon's work is the definitive source for analyzing information capacity of a communications system but his formulation does not …
