INTERROGATIVE SENTENCE IN MINANGKABAU LANGUAGE: X-BAR THEORY

This study discusses the grammatical function of the question words and the internal structure of interrogative sentence in Minangkabau language. The study of this interrogative sentence structure applies X-bar theory as one of the generative syntax subtheories. The data is gained from the interview of Minangkabau language native speaker and analysed by using the distributional method. The result of the analysis shows that the question words for wh-question has two grammatical functions, specifier and complement. For yes-no question, the question word “iyonyo” has one grammatical function, that is complement. The internal structure of interrogative sentence in Minangkabau language is constructed by specifier, complement, and adverb. Key words: interrogative sentence, question word, Minangkabau languag

Adaptive Control for a Class of Nonlinear, Time Varying Rotational Systems

Aerospace systems often exhibit nonlinear, time varying dynamics. Expansive mission profiles, fuel burn or transfer and payload deployments or slung loads can supply additional complexity that can excite the plant dynamics and result in undesirable performance. Because of these often unknown dynamical effects in aerospace systems, an emphasis is placed on controller robustness as significant safety risks are present. Due to the difficulty of predicting uncertainties, robust control can be achieved in two distinct ways. The first approach is to design a control law to be tolerant to a large amount of uncertainty, and the second is to design a control law that can adapt to changing system parameters. It is well known that adaptive controllers can respond to external disturbances and uncertain or nonlinear dynamics. This dissertation investigates the development of adaptive control laws to stabilize and control a class of nonlinear, time varying systems. A direct model reference adaptive control architecture, which includes actuator hedging in the reference model to address actuator bandwidth limitations and uncertainty, is designed and implemented to compensate for dynamical effects that could, for example, be caused by a slung load suspended from a quadrotor. A variety of systems that belong to the same class are presented including a rotating tank system with fluid slosh, and quadrotors with slung loads or actuator failures. A direct model reference adaptive controller complete with a PID or LQR controlled reference model is implemented in each case to enable the system to track attitude trajectories generated by a reference model. Modifications to a baseline direct model reference adaptive controller are applied to attenuate the effects of measurement noise and actuator dynamics. The stability of this control law is investigated via Lyapunov analysis. Simulation results are provided showcasing overall controller performance of attitude control in the presence of both internal and external disturbances, measurement noise, actuator dynamics and actuator failure

Adaptive Control for Nonlinear, Time Varying Systems

It is common for aerospace systems to exhibit nonlinear, time varying dynamics. This thesis investigates the development of adaptive control laws to stabilize and control a class of nonlinear, time varying systems. Direct adaptive control architectures are implemented in order to compensate for time varying dynamics that could, for example, be caused by varying inertia resulting from fuel slosh or settling in a tank. The direct adaptive controller can also respond to external disturbances and unmodeled or nonlinear dynamics. Simulation results are presented for a prototype system that consists of two rotating tanks with time varying inertia due to the motion of fluid inside the tanks. This system is characterized by highly unstable rotational dynamics which are illustrated through simulation. An adaptive regulator is implemented to control the three-dimensional angular velocity to a desired operating point. It is shown that the adaptive controller provides improved performance compared to a baseline linear quadratic regulator designed using a simplified linear dynamics model of the plant. Finally, a direct model reference adaptive controller was implemented to enable the system to track trajectories generated by a reference model. The stability of this control law is investigated via Lyapunov analysis, and simulation results are provided showcasing overall controller performance in the presence of both internal and external disturbances and dynamical effects

Strong solutions and attractor dimension for 2D NSE with dynamic boundary conditions

We consider incompressible Navier-Stokes equations in a bounded 2D domain, complete with the so-called dynamic slip boundary conditions. Assuming that the data are regular, we show that weak solutions are strong. As an application, we provide an explicit upper bound of the fractal dimension of the global attractor in terms of the physical parameters. These estimates comply with analogous results in the case of Dirichlet boundary condition

ESTIMANDO O VALOR DE UMA MARCA (BRAND EQUITY) NO CONTEXTO GLOBAL DA INDÚSTRIA AUTOMOBILÍSTICA

Este artigo analisa em que medida o valor da marca contribui para o preço de um automóvel. O objetivo desta pesquisa é averiguar se automóveis de preço mais elevado fornecem ao consumidor produtos superiores de modo consistente e se, deste modo, o aumento dos preços é justificado. O presente estudo utiliza uma variação do modelo SDR de Brand Equity para investigar o valor de uma marca. Será feita uma comparação entre os atributos dos produtos e os preços de diversos veículos de fabricantes de automóveis dos EUA, Japão e Alemanha. Os atributos do produto e o preço de cada modelo serão categorizados, comparados e, por fim, serão calculados os pontos do preço por produto. Ao calcular a percentagem de variação dos preços para cada veículo em cada classe de automóveis é possível formular um mapa de valores para todos os modelos. Nossos dados revelam que preços mais elevados não só indicam mais atributos no produto, mas também um preço mais elevado para cada atributo do produto. Deste modo, tanto o preço quanto os atributos do produto aumentam a taxas semelhantes ao longo da linha de valor justo, mas aquelas empresas com produtos de preço mais alto também possuem um valor de marca mais elevado, resultando em um preço maior por ponto do produto. Mostramos que os automóveis alemães têm apresentado um valor de marca consistentemente maior do que os construtores de automóveis japoneses e norte-americanos
