Methods of Computing Functional Gains for LQR Control of Partial Differential Equations
… we study various methods for computing functional gains to boundary control problems for the heat equation. These methods require us to solve various equations including the algebraic Riccati equation, the Riccati partial differential equation and the Chandrasekhar partial differential …

Stabilized Finite Element Methods for Feedback Control of Convection Diffusion Equations
… the specific problem of computing the feedback functional gains that are the kernels of the feedback operators defined by solutions of operator Riccati equations. We develop a stabilization scheme based on the Galerkin Least Squares (GLS) method and compare this scheme to the standard Galerkin …

An optimal control problem for a Timoshenko beam
… and compare their robustness property. The functional gains are also compared against their counterpart when an Euler-Bernoulli model is used to describe the dynamics of the beam. Results indicates that the choice of finite element scheme has a direct bearing on the convergence of the …

Dynamic compensators for a nonlinear conservation law
… Projection) by minimizing various energy functionals. These control laws are then applied to the nonlinear model. Different approximation schemes are used to design suboptimal active feedback controllers. This approach provides important practical information. In particular, we show how …

Modeling and Control of SPIDER Satellite Components
… in the wind, SPIDER technology will dictate the functionality and versatility of the satellite much like an arachnid weaving its own web. In the present work, a rigorous mathematical framework based on distributed parameter system theory is presented in describing the dynamics of augmented …

Ecological impacts of biological invasions on native birds in Africa
… fish, mammals and birds. In order to assess functional gains and losses, native birds were categorized into their functional guilds defined by their primary diet. I limited my scope to mainland Africa at the biome level. ArcView GIS 3.3 software was used to map locational data of impacts …

Proper Orthogonal Decomposition for Reduced Order Control of Partial Differential Equations
… Orthogonal Decomposition (POD) to a set of functional gains, and is referred to as the functional gain POD basis. Low order controllers resulting from the functional gain POD basis are compared with low order controllers resulting from more commonly used time snapshot POD bases, with the two …

Computational Approaches to Improving Room Heating and Cooling for Energy Efficiency in Buildings
… Regulator (LQR) controllers and associated functional gains in MATLAB which can be implemented in COMSOL. These "closed-loop" methods are then tested numerically in COMSOL and compared against "open-loop" and average state closed-loop controllers.

Maternal Experiences of Self-Identity and Family Identity after a Child acquires an Acquired Brain Injury: A Constructivist Grounded Theory Analysis
… research has been narrowly focused upon functional gains for individuals and families in rehabilitation while excluding changes in self-identity and family identity. Data were collected via semi-structured interviews and self-report measures of individual mothers' needs and perceptions of …

A comparison of hospital-based and community-based models of cerebral palsy rehabilitation
… models from the perspective of caregivers and functional gains in children. Questionnaires were distributed to caregivers of children with CP at baseline and after three months. The caregivers were 46 in total, with twenty caregivers having children receiving rehabilitation services under an …
