Abstract (sommario):

This paper presents a numerical method and computational results for acoustic noise of electromagnetic origin generated by an induction motor. The computation of noise incorporates three levels of numerical calculation steps, combining both the finite element method and boundary element method. The role of magnetic forces in the production of acoustic noise is established in the paper by showing the magneto-mechanical and vibro-acoustic pathway of energy. The conversion of electrical energy into acoustic energy in an electrical motor through electromagnetic, mechanical, or acoustic platforms is illustrated through numerical computations of magnetic forces, mechanical deformation, and acoustic noise. The magnetic forces were computed through 2D electromagnetic finite element simulation, and the deformation of the stator due to these forces was calculated using 3D structural finite element simulation. Finally, boundary element-based computation was employed to calculate the sound pressure and sound power level in decibels. The use of the boundary element method instead of the finite element method in acoustic computation reduces the computational cost because, unlike finite element analysis, the boundary element approach does not require heavy meshing to model the air surrounding the motor.

Abstract (sommario):

A practical combined computation method of the circumferentially averaged mean through-flow is presented for 3D inverse computations of hydraulic turbomachinery blades to consider the influence of interrelated hydraulic components. A comprehensive computation domain including the runner blades and related components is adopted and the mean flow is calculated altogether by solving a set of rotational flow governing equations simultaneously. The method has been applied to the case of Kaplan turbine. Computational results were compared to experimental data and their agreement was confirmed. Numerical investigation indicates that the mean flow is dependent on the configuration of guide vanes and the effect of runner blades reaches to the far upstream. The importance of properly taking account of the effect of blade geometry and the influence of interrelated hydraulic components is demonstrated.

Abstract (sommario):

PID controller is one of the most widely used control elements in the industry. Over history, people have implemented the PID controller mechanically with pneumatical components, electronically in circuits, or digitally using DSP. However, the pure mechanical realization of PID controllers is rarely studied. This paper presents an analog PID controller based on mechanical computation components, including a mechanical integrator, a mechanical differentiator, mechanical constant multipliers, and a mechanical adder. In this work, those parts are studied respectively with CAE modeling and mathematical derivation. A novel design of mechanical differentiator is also introduced to conduct the calculation of the differential part on the PID controller. This work explores the theoretical possibility of a new form of PID controller realization, that is, applying the method of mechanical analog computation to the implementation of a PID controller.

Abstract (sommario):

This paper develops the theoretical foundation for computations of spatial displacements from the simple geometric features of points, lines, planes, and their combinations. Using an oriented projective three space with a Clifford Algebra, all these three features are handled in a similar fashion. Furthermore, issues related to uniqueness of computations and minimum number of required features are discussed. It is shown that contrary to the common intuition, specification of a minimum of four points (planes) or three lines are necessary for computation of a unique displacement. Only when the sense of the orientations of these features are specified then the minimum number of required features reduces to three for points and planes and two for lines. The results, in addition to their theoretical interest in computational geometry of motion, have application in robot calibration.

Abstract (sommario):

Networks of mechanical resonators embedded in the platform of optomechanics are studied in two quantum information contexts: quantum state reconstruction and measurement based quantum computation. The optomechanical setup considered consists of a harmonically interacting network of resonators one of which is coupled via radiation pressure to a resonant mode of a cavity electromagnetic field. We develop a protocol for reconstructing the state of the network from measurements on the output cavity field. An interaction profile tuned to a set of mechanical quadratures ensures that the cavity field carries a copy of the quadratures’ information. Homodyne detection of the output field provides measurement statistics directly linked to the statistics of the mechanical quadratures from which their marginals can be estimated and standard tomographic techniques applied, recovering the phase space distribution for the network. We provide a method for determining the interaction profiles required and analyse the effectiveness of the scheme for Gaussian states in the case of finite measurements. We also provide some further examples of state reconstruction in similar optomechanics settings. An equivalent setup is that in which the cavity field interacts simultaneously with a collection of noninteracting mechanical modes. Here we implement measurement based quantum computation, giving a summary of cluster state generation in optomechanics and providing a scheme for applying multimode Gaussian operations. Adapting QND measurements on movable mirrors we continuously monitor individual resonators in order to assess the feasibility of using indirect measurements for computation compared to projective measurements performed directly on the cluster. Using a linear cluster state of five modes and taking advantage of the decomposition of single-mode Gaussian operations into four steps, we perform a numerical assessment of a large array of experimental parameters, paring down the list until those that most significantly affect the outcome are distilled. These are the mechanical bath temperature, the mechanical dissipation rate and the cluster squeezing. They place strong restrictions on the experimental parameters in order to ensure high fidelities, with stronger requirements for more highly squeezed clusters. We conclude with a small discussion of currently available experimental settings and remarks on further research possibilities.

Abstract (sommario):

An expansion method for the stationary Schrodinger equation of a particle moving freely in an arbitrary axisymmeric three dimensional region defined by an analytic function is introduced. The region is transformed into the unit ball by means of coordinate substitution. As a result the Schrodinger equation is considerably changed. The wavefunction is expanded into a series of spherical harmonics, thus, reducing the transformed partial differential equation to an infinite system of coupled ordinary differential equations. A Fourier-Bessel expansion of the solution vector in terms of Bessel functions with real orders is employed, resulting in a generalized matrix eigenvalue problem. The method is applied to two particular examples. The first example is a prolate spheroidal billiard which is also treated by using an alternative method. The numerical results obtained by using both the methods are compared. The second exampleis a billiard family depending on a parameter. Numerical results concerning the second example include the statistical analysis of the eigenvalues.

Abstract (sommario):

My work is broadly concerned with the question "How can designs bessynthesized computationally?" The project deals primarily with mechanical devices and focuses on pre-parametric design: design at the level of detail of a blackboard sketch rather than at the level of detail of an engineering drawing. I explore the project ideas in the domain of single-input single-output dynamic systems, like pressure gauges, accelerometers, and pneumatic cylinders. The problem solution consists of two steps: 1) generate a schematic description of the device in terms of idealized functional elements, and then 2) from the schematic description generate a physical description.

Abstract (sommario):

An analysis and comprehensive solution to the direct kinematics problem (DK) of all planar 3-legged platforms with lower pairs, called general planar Stewart-Gough platform (PSGP), is presented. There are 10 types of PSGP DK problem formulation including those with mixed leg architecture.
Planar kinematic mapping expresses pole position and rotation angle of a planar displacement as a point in 3-dimensional projective space represented by 4 homogeneous coordinates. This provides a universal tool for kinematic analysis. Its application will be demonstrated in the derivation of a general algorithm for planar DK. For each type of PSGP, the problem is reduced to a 6th order univariate polynomial whose roots reveal all solutions. An example of a PSGP with 6 real assembly configurations is presented. Furthermore, this algorithm was implemented and tested exhaustively. A complete self-contained version, coded in C, is available at http://www.cim.mcgill.ca/∼paul/. It should be easy to customize and adapt to any given real time micro-controller application.

Includes bibliographical references.
Economic rebound effect is the phenomenon in which price reduction in products and services, induced by energy efficiency increase will cause more consumption leading to an "eat away" of the potential decreases in energy usage. Several researchers have expressed their views on the existence of the effect and the related consequences of such an effect in the micro economic scale. It is recognized that the microeconomic rebound effect will depend on how the price of a good will vary when an efficiency increase is brought about and also on how the quantity consumed may vary when the price changes by a certain amount. A mathematical formulation for this effect is then developed and the two parameters required are found separately for two relevant sectors of the economy. In the first case, the rebound effect is evaluated for the US Aluminum production sector taking into consideration both primary and secondary production. Several models for determining the price elasticity of demand are developed and the share of energy cost in total costs is also found in order to estimate the rebound. The values indicate very low rebound effect in the aluminum industry. A similar trial is conducted for system wide U.S air travel and the rebound estimates are arrived at. Low to moderate take back is observed in this case due to the increased price elasticity unlike the aluminum case where a very low price elasticity of demand pulled down rebound values. In the final sections of the report, discussions including the future trends in rebound effect in the wake of the higher fuel prices and low cost product introduction etc are made. A qualitative description of the macroeconomic rebound effect is also made and conclusions regarding the presence and significance of this effect are drawn. In summarizing it is inferred that even if the rebound effect is statistically significant, it cannot be big enough to completely mask the gains in efficiency improvement. Hence efficiency improvement is inferred as a definite method to decrease energy usage despite the fact that it has its own effectiveness limit set by the rebound.

Abstract (sommario):

The formulation and implementation of a far field boundary condition (FFBC) model for compressible flows is reported in this thesis. This FFBC model, developed for quasi-one-dimensional and two-dimensional flows, aims to permit a substantial reduction of the computational domain, leading to a considerable improvement in the computational efficiency. The present FFBC approach uses asymptotic expansions of the Riemann variables, which are truncated up to the required degree of accuracy. Then, the far field perturbation equations are integrated in time and applied in conjunction with the solution calculated within the computational domain. The propagating information from the computational domain is determined along the outgoing characteristic fronts, based on the estimation of the wave front orientation.
The proposed FFBC model is implemented in conjunction with an implicit finite-difference flow field solver using an alternating direction implicit (ADI) scheme for solving the Euler equations. The discretized form of the governing equations are solved using a time-marching technique until the steady-state solution is reached. An accurate procedure for the solid boundary treatment was also used.
The proposed FFBC model was used for solving typical problems of confined and external compressible flows in subsonic and transonic regimes. For the transonic regime, the proposed FFBC model has been extended for the case of non-isentrophic outgoing flows, which appear behind the shock waves. The solutions obtained are compared with previous theoretical and numerical results. This comparison shows that the proposed FFBC model can generate accurate solutions using a substantially reduced computational domain, which reduces by an order of magnitude the size of the block tridiagonal matrices to be inverted. This leads to a corresponding improvement in the overall computational efficiency.

Wind energy is one of the more viable sources of renewable energy and offshore wind turbines represent a promising technology for the cost effective harvesting of this abundant source of energy. To capture wind energy offshore, horizontal-axis wind turbines can be installed on offshore platforms and the study of hydrodynamic loads on these offshore platforms becomes a critical issue for the design of offshore wind turbine systems. A versatile and efficient hydrodynamics module was developed to evaluate the linear and nonlinear loads on floating wind turbines using a new fluid-impulse formulation - the Fluid Impulse Theory(FIT). The new formulation allows linear and nonlinear loads on floating bodies to be computed in the time domain, and avoids the computationally intensive evaluation of temporal and spatial gradients of the velocity potential in the Bernoulli equation and the discretization of the nonlinear free surface. The module computes linear and nonlinear loads - including hydrostatic, Froude-Krylov, radiation and diffraction, as well as nonlinear effects known to cause ringing, springing and slow-drift loads - directly in the time domain and a stochastic seastate. The accurate evaluation of nonlinear loads by FIT provides an excellent alternative to existing methods for the safe and cost-effective design of offshore floating wind turbines. The time-domain Green function is used to solve the linear and nonlinear free-surface problems and efficient methods are derived for its computation. The body instantaneous wetted surface is approximated by a panel mesh and the discretization of the free surface is circumvented by using the Green function. The evaluation of the nonlinear loads is based on explicit expressions derived by the fluid-impulse theory, which can be computed efficiently.

In this thesis, I consider the problem of designing a collision avoidance system for the scenario in which two cars approach an intersection from perpendicular directions. One of the cars is a human driven vehicle, and the other one is a semi-autonomous vehicle, equipped with a driver-assist system. The driver-assist system should warn the driver of the semi-autonomous vehicle to brake or accelerate if potential dangers of collision are detected. Then, if the system detects that the driver disobeys the warning, the system can override the behavior of the driver to guarantee safety if necessary. A hybrid automaton model with hidden modes is used to solve the problem. A disturbance estimator is used to estimate the driver's reaction to the warning. Then, with the help of a mode estimator, the hybrid system with hidden modes is translated to a hybrid system with perfect state information. Finally, we generalize the solution for the application example to the solution of safety control problem for general hybrid system with hidden modes when the hybrid system satisfies some proposed constraints and assumptions.

Pose estimation, a computer vision technique, can be used to develop a quantitative feedback training tool for long jumping. Key performance indicators (KPIs) such as launch velocity would allow a long jumping athlete to optimize their technique while training. However, these KPIs need a prior knowledge of when the athlete jumped, referred to as the launch frame in the context of videos and computer vision. Thus, an algorithm for estimating the launch frame was made using the OpenPose Demo and Matlab. The algorithm estimates the launch frame to within 0.8±0.91 frames. Implementing the algorithm into a training tool would give an athlete real-time, quantitative feedback from a video. This process of developing an algorithm to flag an event can be used in other sports as well, especially with the rise of KPIs in the sports industry (e.g. launch angle and velocity in baseball).

AbstractWe review sublinear modeling in probabilistic graphical models by statistical mechanical informatics and statistical machine learning theory. Our statistical mechanical informatics schemes are based on advanced mean-field methods including loopy belief propagations. This chapter explores how phase transitions appear in loopy belief propagations for prior probabilistic graphical models. The frameworks are mainly explained for loopy belief propagations in the Ising model which is one of the elementary versions of probabilistic graphical models. We also expand the schemes to quantum statistical machine learning theory. Our framework can provide us with sublinear modeling based on the momentum space renormalization group methods.

Abstract (sommario):

In this study, a 3-D, unsteady, Reynolds-averaged Navier-Stokes (RANS) CFD code coupled to an acoustic calculation is used to predict the contribution of the exit guide vanes to tonal fan noise downstream. The configuration investigated is that corresponding to the NASA Source Diagnostic Test (SDT) 22-in fan rig. One configuration from the SDT matrix is considered here: the approach condition, and outlet guide vane count designed for cut-off of the blade passage frequency. In this chosen configuration, there are 22 rotor blades and 54 stator blades. The stators are located 2.5 tip chords downstream of the rotor trailing edge. The RANS computations are used to obtain the spectra of the unsteady surface pressure on the exit guide vanes. The surface pressure at the blade passage frequency and its second harmonic are then integrated together with the Green’s function for an annular duct to obtain the pressure at locations in the duct. Comparison of the computed sound power level at the exhaust plane with experiment show good agreement at the cut-on circumferential mode. The results from this investigation validate the use of the CFD code along with the acoustic model for downstream fan noise predictions. This validation enables future investigations such as the effect of duct variation on the exhaust tonal power level and the validity of using this method for predicting broadband noise levels.

Abstract (sommario):

In [1] a method to accurately compute the Lyapunov Characteristic Exponents of continuous dynamical systems of arbitrary dimensions was presented. However, it can be computationally expensive, because it requires the computation of the time derivatives of the entries of the exponential of a skew-symmetric matrix. In this paper, we present an implementation of the method in [1] that takes advantage of the fact that some of the computations can be done in parallel. The speedup in the computations depends on the number of CPU cores used and the computer memory. Numerical simulations show improvements in efficiency when using the parallel implementation. Our implementation retains the accuracy of the method in [1] with the added advantage of a speedup in computations. Numerical simulation results are presented for a dynamical system of dimension seven and one of dimension forty-nine.

Abstract (sommario):

Purpose – The rostrum of a paddlefish provides hydrodynamic stability during feeding process in addition to detect the food using receptors that are randomly distributed in the rostrum. The exterior tissue of the rostrum covers the cartilage that surrounds the bones forming interlocking star shaped bones. Design/methodology/approach – The aim of this work is to assess the mechanical behavior of four finite element models varying the type of formulation as follows: linear-reduced integration, linear-full integration, quadratic-reduced integration and quadratic-full integration. Also presented is the load transfer mechanisms of the bone structure of the rostrum. Findings – Conclusions are based on comparison among the four models. There is no significant difference between integration orders for similar type of elements. Quadratic-reduced integration formulation resulted in lower structural stiffness compared with linear formulation as seen by higher displacements and stresses than using linearly formulated elements. It is concluded that second-order elements with reduced integration and can model accurately stress concentrations and distributions without over stiffening their general response. Originality/value – The use of advanced computational mechanics techniques to analyze the complex geometry and components of the paddlefish rostrum provides a viable avenue to gain fundamental understanding of the proper finite element formulation needed to successfully obtain the system behavior and hot spot locations.

Abstract (sommario):

Bio-structures owe their remarkable mechanical properties to their hierarchical geometrical arrangement as well as heterogeneous material properties. This dissertation presents an integrated, interdisciplinary approach that employs computational mechanics combined with flow network analysis to gain fundamental insights into the failure mechanisms of high performance, light-weight, structured composites by examining the stress flow patterns formed in the nascent stages of loading for the rostrum of the paddlefish. The data required for the flow network analysis was generated from the finite element analysis of the rostrum. The flow network was weighted based on the parameter of interest, which is stress in the current study. The changing kinematics of the structural system was provided as input to the algorithm that computes the minimum-cut of the flow network. The proposed approach was verified using two classical problems three- and four-point bending of a simply-supported concrete beam. The current study also addresses the methodology used to prepare data in an appropriate format for a seamless transition from finite element binary database files to the abstract mathematical domain needed for the network flow analysis. A robust, platform-independent procedure was developed that efficiently handles the large datasets produced by the finite element simulations. Results from computational mechanics using Abaqus and complex network analysis are presented.
