Novel Stability Criteria for T--S Fuzzy Systems

2014

In this paper, novel stability conditions for Takagi-Sugeno (T-S) fuzzy systems are presented. The so-called nonquadratic membership-dependent Lyapunov function is first proposed, which is formulated in a higher order form of both the system states and the normalized membership functions than existing techniques in the literature. Then, new membership-dependent stability conditions are developed by the new Lyapunov function approach. It is shown that the conservativeness of the obtained criteria can be further reduced as the degree of the Lyapunov function increases. Two numerical examples are given to demonstrate the effectiveness and less conservativeness of the obtained theoretical resul…

Analytic Exact Upper Bound for the Lyapunov Dimension of the Shimizu–Morioka System

2015

In applied investigations, the invariance of the Lyapunov dimension under a diffeomorphism is often used. However, in the case of irregular linearization, this fact was not strictly considered in the classical works. In the present work, the invariance of the Lyapunov dimension under diffeomorphism is demonstrated in the general case. This fact is used to obtain the analytic exact upper bound of the Lyapunov dimension of an attractor of the Shimizu–Morioka system. peerReviewed

Redesigning work in university classrooms: factors related to satisfaction in engineering and business administration students

2014

Objeto: Con este trabajo se pretende analizar cómo afectan las características del contexto del aprendizaje, es decir, cómo es el trabajo de los estudiantes en la asignatura, al potencial motivador de la asignatura y a la satisfacción de los estudiantes. Diseño/metodología/enfoque: Mediante ecuaciones estructurales (SEM) se ha analizado los datos de una muestra transversal (cursos 2008, 2009 y 2010) de 535 estudiantes de ingeniería industrial y administración de empresas, de una universidad pública española. Aportaciones y resultados: Los resultados, utilizando un instrumento validado y adaptado al mundo docente, demuestran la asociación existente entre las características del tipo de traba…

Estar al otro lado de la mesa. Profesionales de los servicios públicos de empleo ante los dilemas de la activación laboral

2019

Under the paradigm of activation, the Public Employment Services has been reshaped by two levels of contractualization. On one hand, the collaboration of the administration with a network of agents on the programme scheme that make up the active policies of employment. On the other hand, the unemployed person?s access to a compartmentalized offer of services and individually taking responsibility for finding work. This double contractualization reveals redefinition of lowering public responsibility faced with the problem of unemployment that this activation supposes. This paper analyses how this redesign has an impact on how professionals serve the unemployed population. This lays bare, in …

Observer-based adaptive stabilization of a class of uncertain nonlinear systems

2014

In this paper, an adaptive output feedback stabilization method for a class of uncertain nonlinear systems is presented. Since this approach does not require any information about the bound of uncertainties, this information is not needed a priori and a mechanism for its estimation is exploited. The adaptation law is obtained using the Lyapunov direct method. Since all the states are not measurable, an observer is designed to estimate unmeasurable states for stabilization. Therefore, in the design procedure, first an observer is designed and then the control signal is constructed based on the estimated states and adaptation law with the σ-modification algorithm. The uniformly ultimately bou…

From detail to project: House Caiozzo-Facciola

2021

The analysis and understanding, through drawing, of Casa Cajozzo-Facciolà, designed by Pasquale Culotta and Giuseppe Leone, in 1979, on a cliff in Contrada Ogliastrillo in Cefalù, followed a pro- cess that is unlike the traditional process. From the consideration that the detail is thought of as a portion of a whole, which allows, through a close examination, to re-read the global system from which it was provisionally extracted, we proceeded with the analysis of the expected construction system, the balloon frame, and thanks to a close examination of the construction details of which there were sketches with explanatory notes, the proportions, spaces, volumes, surface treatment of the over…

Different energy balances for the redesign of nearly net zero energy buildings: An Italian case study

2015

Abstract The currently developing concept of a Net Zero Energy Building introduces new challenges and research problems. The calculation of a net zero energy balance is heavily influenced by the energy carrier weighting factors that are chosen, which can deeply influence the future energy market towards adopting specific energy technologies. The following paper proposes an analysis of different definitions and conventions for Net Zero Energy Buildings that employ different calculation methodologies and apply different weighting factors to an Italian case study. The case study, which is called “the Leaf House”, is one of the first examples of a nearly net zero energy building in Italy. A bui…

Impulsive control on the synchronization for a class of chaotic Systems

2014

In this paper, the impulsive control problem on the synchronization for a class of chaotic systems is discussed. Based on Lyapunov stability theory, the new impulsive synchronization strategy is presented to realize the chaos synchronization and possesses the wider scope of application. Finally the numerical simulation examples are given to demonstrate the effectiveness of our theoretical results.
