Edges and linearization
… It centers on a hypothesis regarding the linearization of movement chains - the Edge Condition on Copy Deletion, eventually named the Edge Condition in the last chapter, when it receives its final formulation. The empirical phenomena under investigation include (i) predicate cleft …

Analytical SLAM without linearization
… errors and approximations brought by the linearization process in traditional extended Kalman filtering (EKF) SLAM. Convergence rates of the algorithm are established using contraction analysis. Different combinations of sensor information can be exploited, such as bearing measurements, …

Syntactic edges and linearization
… between syntax and phonology. I show that Cyclic Linearization of syntactic structure and constraints on domain-internal movement of multiple specifiers predict unique ordering restrictions at the edges of syntactic domains. As a consequence of cyclic Spell-out and conditions on syntactic …

Linearization of RF Power Amplifiers
Linearization of RF power amplifiers is surveyed, reviewed and analyzed. Cartesian feedback is specifically presented as an effective means of linearizing an efficient yet non-linear power amplifier. This reduces amplifier distortion to acceptable levels and enables the transmission of RF signals …

New architecture for RF power amplifier linearization
Power amplifier linearization has become an important part of the transmitter system as 3G and developing 4G communication standards require higher linearity than ever before. The thesis proposes two power amplifier linearization solutions : two-point architecture and adaptive digital predistortion …

Linearization of a pulse width modulated power amplifier
Currently, the cellphone industry is moving towards an integrated CMOS solution for power amplifiers. Cheaper phones for consumers and better bottom lines for companies are the result of this. The goal of this thesis is to investigate the use of pulse width modulation in a high efficiency …

Solving Nonlinear Aeronautical Problems Using the Carleman Linearization Method
… nontrivial. This thesis will apply the Carleman linearization technique to three model problems: a two-degree of-freedom (2DOF) ballistic trajectory, Blasius' boundary layer, and Van der Pol's equation and evaluate how well the technique can adequately approximate the solutions of these ordinary …

Finding linearization violations in lock-free concurrent data structures
… the correctness of concurrent algorithms is the linearization property. This thesis presents a tool for automatic dynamic checking of concurrent programs under the Total-Store-Order (TSO) memory model and a methodology for finding linearization violations automatically with the tool.

The Duffing Oscillator And Linearization Techniques For Its Motion Constants
… linear representation is found through Carleman Linearization. This is a technique used to linearize a finite dimensional nonlinear system of differential equations to an infinite dimensional, linear, autonomous system of differential equations. Using Carleman Linearization, the Duffing equation …

Feedback linearization and adaptive control of a nonlinear aeroelastic system
In this thesis, it is exhibited that although, the aeroelastic system is not input-state feedback linearizable, a partial linearized representation of the system in dimension three can be obtained. Based on this partially linearized representation, a new inverse controller was derived and …

Fault tolerant control for nonlinear aircraft based on feedback linearization
… initially fault-free flight, the feedback linearization theory plays an important role to provide a baseline control approach for de-coupling and stabilizing a non-linear statically unstable aircraft system. Then several reconfigurable control strategies are studied to provide further …

Segmental multi-point linearization for topology optimization and reliability analysis
… is approximated. A segmental multi-point linearization (SML) method is proposed for a more accurate estimation of failure probability and its gradient. Numerical examples show that the RBTO algorithm based on the SML is more stable numerically and is able to converge to a solution that is …
