The present study analyzes the contribution which natural elements in the city make to restorativeness, that is, the potential of certain environments to help recover the capacity to focus attention, reduce mental fatigue, and reduce stress. We presented photographs of 12 urban scenes (streets, industrial areas, and buildings) with and without vegetation to(More)
—A new distributed MPC algorithm for the regulation of dynamically coupled subsystems is presented in this paper. The current control action is computed via two robust controllers working in a nested fashion. The inner controller builds a nominal reference trajectory from a decentralized perspective. The outer controller uses this information to take into(More)
The aim of this work was to develop an instrument (Coping Strategies for Skin Problems Questionnaire) suitable for identifying the coping strategies people use for general skin problems. We analyzed its psychometric properties when applied to a sample of 299 individuals. Factor analysis shows a 6-factor structure referring to the wish to change,(More)
Social relationships had been important in explanation and prediction of attachment to places. Although some have asserted the importance of physical aspects of the environment in the formation of attachment ties to a place, the social environment is required for the formation of bonds to a place, although strong emphasis on the social aspect has been(More)
INTRODUCTION Environmental supports for physical activity may help residents to be physically active. However, such supports might not help if residents' perceptions of the built environment do not correspond with objective measures. We assessed the associations between objective and perceived measures of the built environment among adults in Cuernavaca,(More)
We propose a distributed model predictive control approach for linear time-invariant systems coupled via dynamics. The proposed approach uses the tube MPC concept for robustness to handle the disturbances induced by mutual interactions between subsystems; however, the main novelty here is to replace the conventional linear disturbance rejection controller(More)
In the current socioeconomic situation, the need to improve employability of potential workers is especially relevant. The aim of this study was to evaluate the efficacy of an intervention program focusing on improving employability of university students. To do this, a two-group study was designed: one group undertook the intervention program and the other(More)
This paper presents a study examining whether self-efficacy and intrinsic motivation are related to environmentally responsible behavior (ERB). The study analysed past environmental behavior, self-regulatory mechanisms (self-efficacy, satisfaction, goals), and intrinsic and extrinsic motivation in relation to ERBs in a sample of 156 university students.(More)
— This paper presents a new approach to deal with the dual problem of system identification and regulation. The main feature consists of breaking the control input to the system into a regulator part and a persistently exciting part. The former is used to regulate the plant using a robust MPC formulation, in which the latter is treated as a bounded additive(More)
This paper studies a fundamental relation that exists between stabilizability assumptions usually employed in distributed model predictive control implementations, and the corresponding notions of invariance implicit in such controllers. The relation is made explicit in the form of a theorem that presents sufficient conditions for global stabilizability. It(More)
