In this paper we propose a non-homogeneous observer-based-output feedback scheme for the double integrator system. The control scheme is composed by two non-homogeneous structures. It resembles a non-homogeneous state feedback controller, where the unmeasurable state is replaced by the that provided by a non-homogeneous observer. Compared to other reported schemes, the closed-loop system is not homogeneous of negative degree, so it is not possible to use the results established for homogeneous systems. To overcome this problem, the finite-time stability analysis is carried out by means of (local) strict Lyapunov functions.

This paper addresses the problem of global output feedback stabilization for a class of inherently higher-order uncertain nonlinear systems subject to time-delay. By using the homogeneous domination approach, we construct a homogeneous output feedback controller with an adjustable scaling gain. With the aid of a homogeneous Lyapunov-Krasovskii functional, the scaling gain is adjusted to dominate the time-delay nonlinearities bounded by homogeneous growth conditions and render the closed-loop system globally asymptotically stable. In addition, we also show that the proposed approach is applicable for time-delay systems under nontriangular growth conditions.

This thesis presents theoretical and experimental studies on decentralised velocity feedback control for thin homogeneous and lightweight sandwich panels. This research is motivated by the increasing interest in lightweight design for fuel efficient transportation vehicles. Lightweight sandwich panels are very appealing due to their high stiffness to weight ratio but also exhibit undesirable sound transmission properties which could cause problems with vehicle interior noise. The aim of this work is to assess the performance of decentralised velocity feedback control on lightweight sandwich panels. The first part of this thesis presents the theoretical model used to predict the structural response, sound radiation and sound transmission through active panels with decentralised velocity feedback loops. The model is then used in simulation studies on the intrinsic limitation of decentralised feedback control for thin homogeneous and sandwich active panels under distributed deterministic and stochastic excitations in the whole audio frequency range. The results suggest that decentralised velocity feedback control on lightweight sandwich panels is more efficient and can be applied over wider range of audio frequencies than for conventional thin homogeneous panels. The second part of this thesis presents experimental and simulation studies on a control system with five decentralised control units with proof-mass electrodynamic actuators, installed on conventional aluminium panel and a honeycomb sandwich panel. This study provides insight in the open and closed-loop response of the control units and gives a good understanding of the interaction between the panels and the control system. The results suggest that a practical control system that implements decentralised velocity feedback can offset some of the undesired sound transmission properties of lightweight sandwich structures by efficiently reducing structural vibration and sound power radiation in the mid audio frequency range.

The present study seeks to advance understanding of intragroup trust and team diversity. The dynamic interrelationships between intragroup trust, information sharing, and performance were examined over feedback cycles in interdisciplinary and homogeneous teams. In a three-hour lab session, participants completed a management simulation task in teams of four. Performance feedback was administered and process variables were measured periodically throughout the task. Several hypotheses were posed predicting differences between team type as well as the dynamic influence of performance feedback on the nature of trust. Findings both add to knowledge about the development of trust as well as point to future research directions. Although trust displayed an overall positive linear trend independent of team type, Cycle 1 performance feedback contributed to the trust trajectory. Additionally, considerations for operationalizations of information sharing and team performance are discussed in light of findings.

This thesis presents the development of a model of the Medical Isotope Production Reactor (MIPR): a conceptual Aqueous Homogeneous Reactor (AHR). The model is a point kinetics model with zero and one-dimensional thermal hydraulic feedbacks. Three versions of the model of increasing complexity are presented and a number of scenarios are modelled with each version. The results of these simulations shows the stability of the reactor against reactivity insertions caused by the strong negative reactivity feedbacks inherent to AHRs. The first version of the model is modified using intrusive polynomial chaos in order to simulate the effects of uncertainty in key parameters. This allows a novel study into which physical parameters and processes are important at each stage of a transient and in determining steady state conditions. The final version of the model is used to model the CRAC-43 experiment and, after modification to include the delay of radiolytic gas production which accompanies the start up of an AHR, good agreement was found between model and experiment. The development of the equations, correlations and parameters used in the model is approached from the point of view of the governing physics. This approach to model development enables a comprehensive exploration of the physical processes underpinning the behaviour of AHRs. As well as being one of the most complete and fundamentally based models of an AHR presented within the literature, the final model is also extremely versatile and general. Given the appropriate input neutronic and thermal-hydraulic data the model presented in this thesis should be able to simulate a very wide range of AHR behaviour.

Les travaux présentés dans cette thèse portent sur la stabilisation d'une classe d'équations aux dérivées partielles non linéaires. Il s'agit d'un modèle discrétisé de l'équation de Vlasov-Poisson décrivant l'évolution spatio-temporelle, dans un plasma, d'une fonction de distribution de particules chargées. Dans une première étape, nous avons abordé la stabilisation des systèmes dynamiques en temps fixe (i.e. la stabilisation en temps fini avec un temps d'établissement uniformément borné). Des critères relaxant des résultats existants dans la littérature ont été établis. En effet, nous avons montré que, pour un système dynamique, la combinaison de la stabilité lente (au sens polynomiale) et de la stabilité rapide (au sens temps fini) conduit à une stabilité en temps fixe. Diverses applications sur le système de Vlasov-Poisson discrétisé concernent aussi le système double intégrateur avec observateur et les systèmes bilinéaires de dimension infinie où pour chacun de ces systèmes, le retour stabilisant et /ou les observateursen temps fixe sont construits et testés numériquement. Dans une seconde étape, nous nous sommes intéressés à la stabilisation en temps petit des systèmes dynamiques variants dans le temps. En fait, la notion de temps petit est couramment utilisée dans la théorie de la commandabilité. Pour la stabilisation, ce temps petit est situé entre le temps fini et le temps fixe. Nous avons élaboré des résultats théoriques basés sur la méthode énergétique garantissant la convergence de la solution, vers zéro, en temps petit. Cela, est obtenu moyennant une excitation temporelle d'une fonction positive non intégrable au sens de Lebesgue. Puis, nous avons appliqué nos résultats sur des exemples modèles comme l'équation de transport avec contrôle frontière, l'équation d'onde soumis à un contrôle frontière du type Wentzell. Également, pour les systèmes bilinéaires en dimension finie et infinie qui sont, en outre, des modèles types de Vlasov-Poisson discrétisé. Pour chaque système, nous avons élaboré son retour d'état dont la construction est basée sur l'intégration des excitations temporelles et uniformes
The work presented in this thesis concerns the stabilization of a class of nonlinear partialdifferential equations. It is a discretized model of the Vlasov-Poisson equation describing the spatial and temporal evolution, in a plasma, of a distribution function of charged particles. In a first step, we addressed the stabilization of the dynamical systems in fixed time (i.e. stabilization in finite time with a uniformly bounded). Criteria relaxing existing results in the literature have been established. Indeed, we have shown that, for a dynamical system, the combination of slow stability (in the polynomial sense) and fast stability (in the finite time sense) leads to a stability in fixed time. Various applications on the discretized Vlasov-Poisson system also concern the double integrator system with observer and the bilinear systems in infinite dimension where for each of these systems, the stabilizing feedback and/or observers in fixed time are constructed and numerically tested. In a second step, we are interested in the small time stabilization of time varying dynamical systems. In fact, the notion of small time is commonly used in theory of controllability. For stabilization, this small time is located between finite time and the fixed time. We have developed theoretical results based on the energy method guaranteeing the disappearance of the solution in small time. This is obtainedby means of a time excitation of a positive function not integrable in the sense of Lebesgue. Then, we have applied our results on model examples such as the transport equation with boundary control, the wave equation subject to a boundary control of the Wentzell type. Also, for finite and infinite dimensional bilinear systems which are, in addition, typical discretized Vlasov-Poisson models. For each system, we have elaborated its feedback whose construction is based on the integration of temporal and uniform excitations

In this thesis, a polynomial nonlinear system, modelled by T-S fuzzy model with added disturbances, is studied. Based on non-quadratic, homogeneous Lyapunov function, both controller and observer are considered in the analysis where Euler's homogeneous polynomial theorem is used to avoid the derivative term dot Q(x) that is seen in the existing papers. After some background reviewed, we started with fuzzy system models established by Taylor series. To tackle the derivative Lyapunov dot Q(x) terms and the zero row structure in the input matrix B(x) in the existing papers, Euler homogeneous polynomial theory is applied to derive the stabilization condition in LMI formulation and then converted into SOS form so that SOSTOOLS is used to for synthesis analysis. 　Finally, Sum of Square is applied to solve for the Lyapunov Q(x) and controller/observer gains, thereby ensuring the stability of the closed-loop feedback system as well as the observed-state feedback control system. Several examples are provided in Chapter 5 to demonstrate the analysis is effective.

The main contribution in this thesis is static output feedback controller design of H1 continuous fuzzy system. And we can solve the inequalities derived from non-quadratic Lyapunov function and its time gradient. It’s a two-step procedure for solving output feedback control gain, step 1: solve for state feedback gain (for common P theorem), step 2: solve for static output feedback gain (for homogeneous polynomial P(x) theorem). A non-quadratic Lyapunov function derived from Euler’s homogeneous polynomial theorem has following form V (x) = x'P(x)x = 1/(g(g-1))x'∇xxV (x)x。 In numerical simulation, we solve for state feedback gain first and then solve for static output feedback gain with sum-of-squares approach.

In this paper, we study switching static output feedback control problem for both continuous- and discrete-time polynomial fuzzy systems. The stabilization of the systems is proved with minimum-type piecewise Lyapunov functions, which have the form V(x)=\min_{1\leq l \leq N}\big\{V_l(x)\big\}. Switching mechanism of the controllers is also based on piecewise Lyapunov functions. In continuous-time systems, in order to remove non-convex term \dot P(x), via Euler's theorem for homogeneous functions we establish piecewise functions as follows. V_l(x)=x^TP_l(x)x=\frac{1}{g(g-1)}x^T\nabla_{xx}V_l(x)x In discrete-time systems, the piecewise functions are defined as V_l(x)=x^TP_l^{-1}(\tilde x)x$ to prevent problems where \tilde x is the set of states whose corresponding row in B_i(x) are empty. Further details are described in the text. In numerical examples, stability conditions and controller synthesis are tested and solved via sum-of-squares approach.

In this thesis, we investigate H∞ control problem for both continuous- and discrete-time polynomial fuzzy systems, and to design static output feed- back controllers. The stabilization of the underlying systems can be proved via homogeneous Lyapunov method. This thesis studies static output feed- back control that is more appropriate in practical than state feedback con- trol. In continuous-time systems, Euler’s homogeneous polynomial theorem is used to formulate a Lyapunov function. It has the following form V (x) = xT P (x)x = 1 xT ∇xxV (x)x g(g − 1) In discrete-time systems, the Lyapunov function is formulated by V ( x ) = x T P − 1 ( x ̃ ) x where x ̃ are part of x that are not directly affected by the control input. This restriction is to avoid problems when doing simulation. The details will be described later. In numerical simulations, examples are solved via the sum-of-squares approach.

The conclusion summarizes key findings of the empirical chapters and offers an answer to the core puzzle of the book about the rise of minority activism since the 1970s: it was global human rights ideas and institutions that transformed the movement actorhood of all three minority groups in Japan, galvanizing their activism and enabling their significant gains. The chapter also underscores the book’s theoretical contributions, pointing to the need to understand the capacity of global human rights to transform movement actorhood, rather than to assume rational actors with set interests, and illustrating the different patterns of impact of global human rights depending on the local actors’ starting position, thus offering a corrective to one-dimensional understanding of globalization as isomorphic forces shaping all local actors homogeneously. The local-to global-feedback loop is another contribution of this research, highlighting the mechanisms of norm consolidation and norm expansion in the international arena. The research also suggests important lessons for the future of global human rights.

AbstractIn this paper, we investigate the wave solutions of a stochastic rotating shallow water model. This approximate model provides an interesting simple description of the interplay between waves and random forcing ensuing either from the wind or coming as the feedback of the ocean on the atmosphere and leading in a very fast way to the selection of some wavelength. This interwoven, yet simple, mechanism explains the emergence of typical wavelength associated with near inertial waves. Ensemble-mean waves that are not in phase with the random forcing are damped at an exponential rate, whose magnitude depends on the random forcing variance. Geostrophic adjustment is also interpreted as a statistical homogenization process in which, in order to conserve potential vorticity, the small-scale component tends to align to the velocity fields to form a statistically homogeneous random field.

Oscillating chemical reactions have the distinct property of a periodic or aperiodic oscillatory course of concentrations of reacting chemical species as well as temperature. This behavior is due to an interplay of positive and negative feedback with alternating dominance of these two dynamic effects. For example, an exothermic reaction produces heat that increases temperature, which in turn increases reaction rate and thus produces more heat. Such a thermokinetic effect is thus autocatalytic and represents a positive feedback. When run in a flow-through reactor with a cooling jacket, the autocatalysis is eventually suppressed if the reactant is consumed faster than it is supplied. At the same time, the excess heat is being removed via the jacket, which tends to quench the system. The latter two processes are inhibitory and represent a negative feedback. If the heat removal is slow enough so as not to suppress entirely the autocatalysis, but fast enough for temperature to drop before there is enough reactant available via the feed to restore autocatalysis, then there are oscillations in both temperature and concentration of the reactant. Examples of these thermokinetic oscillations are combustion reactions, which typically take place either in homogeneous gaseous or liquid phase or in the presence of a solid catalyst, thus representing a heterogeneous reaction system. Of more interest in the present context are reactions where thermal effects are often negligible, or the system is maintained at constant temperature, as is the case with homogeneous chemical reactions taking place in a thermostated flow-through reactor, as well as biochemical reactions in living cells and organisms. Autocatalysis can easily be realized in isothermal systems, where instead of a heat-producing reaction there will typically be a closed reaction pathway, such that species involved are produced faster by reactions along the pathway than they are consumed by removal reactions. As an example, let us examine the well-known Belousov–Zhabotinsky (BZ) reaction of bromate with malonic acid catalyzed by cerium ions in acidic solution.

The goal of this paper is to present a word-final target phoneme automated segmentation method based on cross-correlation coefficients computed between a reference sound wave and a sample sound wave. Most existing Speech Sound Disorder (SSD) Screening solutions require human intervention to a greater or lesser extent and use segmentation methods based on hard-coded time frames. Moreover, existing solutions extract features from the frequency domain, which entails large amounts of computational power to the detriment of real-time feedback. The pre-processing algorithm proposed in this paper, implemented in a Python version 3.7 script, automatically generates 2 new .wav files corresponding to the phonemes found in word-final position in the initial sound waves. The newly-generated .wav files are meant to be used as valid and homogeneous input in a subsequent classification stage aimed at rigorously discriminating mispronunciations of the target phoneme and assist Speech-Language Pathologists (SLPs) with the SSD screening.

Abstract Widely separated and internally homogeneous political camps, each responsible to its respective base, characterize American politics in the early 21st century. The resulting government is beset with gridlock, obstruction, and the inability to compromise to get things done. We focus on the difference between the mean ideological positions of the Democratic and Republican delegations in the US House, along with the intraparty variance within each of the delegations. Our theoretical model of polarization—driven by the feedback loop binding national party discipline to voting in Congressional districts and abetted by voter party loyalties and the influence of activists within each party—accounts for the inverse relationship between party separation and intraparty variance in Congress. We focus on processes that reinforce polarization operating “behind the scenes,” to which even the involved actors may be oblivious. We show that, once a polarization threshold is crossed, office-seeking parties and candidates gain from putting more emphasis on mobilizing their base rather than appealing to the middle.

Climate change and institutional forest management practices are leading to more frequent and severe wildfire events around the world, a trend that is projected to increase in coming years. Wildfire plays an important role in maintaining ecological systems, but wildfires also pose threats to health, safety, infrastructure, and important ecosystem services. Reactionary response to these threats has predominantly informed management decisions in recent decades and greater focus on mitigation and adaptation is needed. Through a community directed consultation process, the goal of this work has been to provide direct, operational information to aid in local management decision making for a First Nations community in British Columbia, Canada. Here we use a combination of field sampling and high-resolution Airborne Laser Scanning (ALS) data to assess vertical and horizontal fuel loading at fine resolution (~10m2). Our analysis found a high degree of fuel loading heterogeneity in areas characterized as homogeneous using coarser fuel layers and provided a means of identifying high fire risk areas that may be targeted for ecosystem rehabilitation aimed at reducing current and future fire risk. We discuss how this spatially explicit data can be used to evaluate feedback between forest dynamics and fuel loading; information critical for managing forests for multiple objectives into the future. Following our analysis, we compiled our results for the community into an interactive decision support web mapping platform designed with the goal of user friendly, accessible land managment planning, avoiding the need for technical expertise and internal capacity.

This article relies on a large-scale field experiment in Mexico to measure the effects of two ability-grouping models (tracking and heterogeneous/bimodal groups) on student learning outcomes during middle school. Both strategies yielded an average learning gain of 0.08 of a standard deviation. We find larger and more persistent effects among initially high-achieving students and no significant effects among low achievers. Students in top tracking enjoyed multiple advantages, particularly a concentration of high-performing peers and a very homogeneous classroom, that facilitated the teacher's work and increased students' effort levels. Bimodal classes fostered greater effort levels among top students, while teachers induced less competition and allocated more time to practice and feedback activities, to the detriment of lecture time. Our results support the allocation of students to homogeneous classes to maximize performance gains among top students without hurting low achievers. Fostering inclusive learning among weaker students would require complementary investments under both models.
