1. Raižytė, J. Understanding the perceived magnitude of inequality: who broke the social ladders?.

Degree: 2015, Universiteit Utrecht

In recent years, questions regarding economic inequalities have attracted an increasing number of research in the field on interdisciplinary social sciences. However, not enough attention has yet been paid for understanding the perceptions of economic inequalities and, particularly, the perceived size of inequalities in the society. The central research question set in this analysis explores how the magnitude of economic inequality is perceived in European Union Member states and how possible variation in these perceptions can be explained. Seven theory-based hypotheses are formulated in order to test both individual and contextual country-level effects on perceived magnitude of inequality. Assumed explanations at individual level include different demographic characteristics, subjective social status, expectations towards social mobility and attitudes towards welfare state. Marco level factors, included in formulated hypotheses, consider selected macroeconomic parameters, post-Soviet heritage and typology of welfare regimes. Standard Eurobarometer survey data (81.5) is chosen as the primary data set for statistical analysis. The designed methodological approach combines multiple and multilevel regression modelling in assessing explanatory capacity of chosen micro and macro-level indicators. The results yield for diverse explanation of perceived magnitude of economic inequality, including both individual and contextual country-level factors. Findings also reveal that personal believes and attitudes carry the largest part in overall explanatory capacity of the presented research model. More specifically, lower self-placement in society, negative expectations of future social mobility and higher support for welfare state prove to be the most significant explanatory factors for amplified perceptions of inequality magnitude.

2. Palmeira, Alessandra Helena Kimura. Estabilidade de sistemas amostrados com atuadores saturantes em magnitude e taxa de variação.

Degree: 2015, Universidade do Rio Grande do Sul

Neste trabalho, aborda-se o problema de estabilidade de sistemas com dados amostrados periodicamente, na presença de atuadores saturantes em posição e em taxa de variação. Os atuadores são modelados como sistemas de primeira ordem com saturação de entrada (saturação de magnitude) e do estado (saturação de taxa de variação). No modelo, considera-se que o sinal de controle é mantido constante entre dois instantes de amostragem consecutivos, enquanto as dinâmicas da planta linear e do atuador saturante são em tempo contínuo, i.e., não é feita discretização do sistema. O efeito da amostragem aperiódica é considerado através de um looped -funcional, derivado do funcional de Lyapunov-Krasovskii. O método desenvolvido relaciona uma função quadrática de Lyapunov e o funcional, considerando a amostragem assíncrona e o atuador saturante. Assim, se a derivada temporal do funcional ao longo das trajetórias do sistema for definida negativa, verifica-se que a função de Lyapunov é estritamente decrescente nos instantes de amostragem. Os efeitos das saturações são considerados por meio do uso da condição de setor generalizada. A partir do looped-funcional, da função de Lyapunov e das relações de setor generalizadas, são formuladas condições que permitem caracterizar a estabilidade e projetar ganhos estabilizantes da origem do sistema amostrado, em contexto local e global, através de algoritmos baseados na solução de LMIs. São propostas condições para maximização da estimativa da região de atração da origem ou, dado um conjunto de condições iniciais, para maximização do limite superior do intervalo de amostragem. As condições estabelecidas são válidas para o sistema com acesso a todos os estados, como também, no caso dos estados do atuador não estarem disponíveis `a medição.

This work addresses the problems of stability and stabilization of sampled-data systems taking into account aperiodic sampling and magnitude and rate saturating actuactors. The actuators are represented by a first-order system subject to input (magnitude saturation) and state (rate) saturation. In the considered model, the control signal is assumed to be constant between two successive sampling instants, while the dynamics of the linear plant and the saturating actuator are in continuous-time, i.e., no discretization is performed. The aperiodic sampling is taken into account from the method based on the input delay approach via looped-functional, derived from a time-dependent Lyapunov-Krasovskii functional. The developed method is based on a particular functional, that is related to a Lyapunov function. It is shown that if the time derivative of the looped- functional along the trajectories of the continuous-time system is strictly negative, then the Lyapunov function is strictly decreasing at sampling instants. The actuator saturations are taken into account from the use of a generalized sector condition. From the looped-functional, the Lyapunov function and the generalized sector conditions, the developed results lead to conditions that can be solved as LMI…
