Stabilization and lx -gain analysis of switched positive systems with actuator saturation
2014
This paper is concerned with the problems of stability and l 1 -gain analysis for a class of switched positive systems with time-varying delays and actuator saturation. Firstly, a convex hull representation is used to describe the saturation behavior. By constructing a multiple co-positive Lyapunov functional, sufficient conditions are provided for the closed-loop system to be locally asymptotically stable at the origin of the state space under arbitrary switching. Then, the l 1 -gain performance analysis in the presence of actuator saturation is developed. Finally, two numerical examples are provided to demonstrate the effectiveness of the proposed method.
Self-Representation of Children Suffering from Congenital Heart Disease and Maternal Competence
2013
Background: Child development may be subject to forms of motor, physical, cognitive and self-representation impairments when complex congenital heart disease (CHD) occurs. In some cases, inadequacy of both self-representation as well as the family system are displayed. It seems to be important to search the likely internal and external resources of the CHD child, and the possible connections among such resources, which may help him/her to manage his/her own risk condition. Design and Methods: The research project inquires the possible resources related to the self-representation and self-esteem levels of the CHD child, and those related to maternal self-perception as competent mothers. A gr…

Tra ambiguità e malinteso: schermaglie di una «battaglia per l’identità» in una conversazione tra mafiosi
2015
Gli scambi comunicativi tra membri di Cosa Nostra sono regolati dalla duplice restrizione della legge del silenzio verso il mondo esterno e dall'obbligo di dire la verità all'interno del sodalizio. A tal fine, il linguaggio mafioso ricorre all’obliquità semantica che fornisce ai parlanti un ampio margine di libertà consentendo loro di non esplicitare le proprie reali intenzioni. È questa la ragione per la quale Tommaso Buscetta ha definito Cosa Nostra come "il regno dei discorsi incompleti". L'ordine del discorso mafioso si basa spesso sulla pratica di quello che Jankélévitch ha definito il "malinteso doppiamente beninteso” uno scambio che si fonda non tanto su una falsa relazione quanto su…
Spin-orbit coupling constants from coupled-cluster response theory
2000
A scheme for the calculation of spin-orbit coupling constants using coupled-cluster (CC) electronic structure methods is described based on response-theory expressions for transition properties. An implementation is reported for singlet–triplet transitions within the coupled-cluster singles and doubles (CCSD) approximation. An atomic mean-field representation of the spin-orbit interaction is used to simplify the calculation of spin-orbit coupling constants. Sample calculations are presented for spin-orbit couplings for the 11Σ+→13Π transitions for BH and AlH and for the 11A′→13A″ and the 13A″→11A″ transitions for the silylenes HSiX, X=F, Cl, Br, and are compared to results obtained from ful…
Immigrant representations in two newspaper articles from the Daily Telegraph
2009
Tämän tutkimuksen tarkoituksena oli selvittää millaisia representaatioita ja identiteettikategorioita maahanmuuttajille rakennettiin brittiläisen The Daily Telegraph sanomalehden Internet-sivuilla. Aihe oli sovelias tutkimuksen alaiseksi, koska maahanmuuttajan representaatiosta sanomalehdistössä oli vähän tutkimusta. Ilmiötä oli jonkin verran tutkittu suomenkielisissä sanomalehdissä. Tutkimus oli vertaileva ja metodityökaluna käytettiin kriittistä diskurssianalyysia. Tutkimusaineisto koostui kahdesta artikkelista jotka oli julkaistu joulukuussa 2008. Tutkimuksessa vertailtiin Seija Lambergin pro gradussa listattuja kuutta identiteettikategoriaa tässä tutkimuksessa käytetystä aineistosta es…
Wellness Centres on Costa Crociere Cruises: Body, Space, and Representation from an Anthropological and Linguistic perspective
2016
Many tourist services are connected to the care of the body. The tourist industry proposes different vacation opportunities where the body is the main focus of the experience. This kind of tourism implies specific services that show a particular universe of representation and particular languages. In this context, cruise tourism is an interesting case to analyze because a part of its services gives a central role to the body which, on-board, organizes and is organized within dedicated spaces and times. Cruise ships provide spaces for the wellness of the passengers such as swimming pools, gyms, spas or beauty centres. The analysis proposed in this work is based, on one hand, on a recent anth…
Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo
2020
The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…
Virtual Museum Net
2006
A project named ”Virtual Museum Net of Magna Graecia” is presented, whose objective is to provide an unitary image of the archaeological heritage of Calabria (a Southern Italian region), through Computer Technology, Multimedia Designing and Virtual Reconstructions. The project aims to encourage the technological transfer of the most advanced researches in the exploitation and conservation sector of the Cultural Heritage. The ”Virtual Museum Net of Magna Graecia” project is included in the context of Knowledge Media Design for Museums. This project links the museum scenery and multimedia, in order to use technology as system of representation.
