Stochastic ship roll motion via path integral method
2010
ABSTRACTThe response of ship roll oscillation under random ice impulsive loads modeled by Poisson arrival process is very important in studying the safety of ships navigation in cold regions. Under both external and parametric random excitations the evolution of the probability density function of roll motion is evaluated using the path integral (PI) approach. The PI method relies on the Chapman-Kolmogorov equation, which governs the response transition probability density functions at two close intervals of time. Once the response probability density function at an early close time is specified, its value at later close time can be evaluated. The PI method is first demonstrated via simple …
Il sistema dei mulini nel territorio delle Madonie in Sicilia: le ragioni della conservazione e le ragioni
2014
Nell'ambito del patrimonio tradizionale delle Madonie, nei suoi molteplici aspetti ambientali e architettonici, storici e culturali, rientra il complesso dei mulini, disposti in sequenza perché alimentati dallo stesso flusso d'acqua, della Flomaria presso Polizzi Generosa. Alla luce delle tematiche attuali riguardanti la conservazione e, in particolare, rispetto al rinnovato concetto di conservazione integrata, si analizzano le caratteristiche di questo specifico patrimonio culturale, in vista di una valorizzazione nel segno della continuità passato-presente.

Lost in Transition: A Systematic Review of Neonatal Electroencephalography in the Delivery Room—Are We Forgetting an Important Biomarker for Newborn …
2017
Background: Electroencephalography (EEG) monitoring is routine in neonatal intensive care units (NICU) for detection of seizures, neurological monitoring of infants following perinatal asphyxia, and increasingly, following preterm delivery. EEG monitoring is not routinely commenced in the delivery room (DR). Objectives: To determine the feasibility of recording neonatal EEG in the DR, and to assess its usefulness as a marker of neurological wellbeing during immediate newborn transition. Methods: We performed a systematic stepwise search of PubMed using the following terms: infant, newborns, neonate, delivery room, afterbirth, transition and electroencephalography. Only human studies describ…
La educación auditiva como eje vertebrador de la educación musical en la Educación Secundaria Obligatoria
2013
El presente trabajo se enmarca dentro de un estudio de mayores dimensiones motivado por el interés de los autores en la didáctica de la audición musical, convencidos de que los principios fundamentales sobre los que se debería apoyar la educación musical actualmente en la Educación Secundaria Obligatoria son, por una parte, la necesidad de una mayor contribución de la misma a una educación integradora de todas las dimensiones del ser humano, y por otra, la conveniencia de otorgarle un mayor protagonismo a la educación auditiva en el proceso de enseñanza-aprendizaje de la materia de música en dicha etapa educativa. El propósito es dar respuesta a una serie de interrogantes que surgen en torn…
Predicting First-Year College Student Retention: Validation of the College Persistence Questionnaire in a Spanish Sample
2019
This paper analyzes the factorial and predictive validity of a Spanish adaptation of the College Persistence Questionnaire (SCPQ) on the retention of first year students (FYS) at university. The participants were 490 FYS from two public universities in Southern Europe (Spain). Factorial analysis of the SCPQ (&chi
Integrals and selections of multifunctions with values in an arbitrary banach space
2017
In this note we will address some recent as well as classical results on multivalued integrals for multifunctions taking values in the hyperspace of convex weakly compact subsets of a general Banach space. In particular the existence of selections integrable in the same sense of the corresponding multifunctions will be considered.
Approximation by step functions of Banach space valued nonabsolute integrals.
2008
The approximation of Banach space valued nonabsolutely integrable functions by step functions is studied. It is proved that a Henstock integrable function can be approximated by a sequence of step functions in the Alexiewicz norm, while a Henstock-Kurzweil-Pettis and a Denjoy-Khintchine-Pettis integrable function can be only scalarly approximate in the Alexiewicz norm by a sequence of step functions. In case of Henstock-Kurzweil-Pettis and Denjoy-Khintchine-Pettis integrals the full approximation can be done if and only if the range of the integral is norm relatively compact. It is also proved that if the target Banach space X does not contain any isomorphic copy of c_0, then the range of t…
The Variational Mcshane Integral in Locally Convex Spaces
2009
The variational McShane integral for functions taking values in a locally convex space is defined, and it is characterized by means of the p-variation of the indefinite Pettis integral
Characterizations of Kurzweil--Henstock--Pettis integrable functions.
2006
We prove that several results of Talagrand proved for the Pettis integral hold true also for the Kurzweil--Henstock--Pettis integral. In particular the Kurzweil--Henstock--Pettis integrability can be characterized by suitable properties of the operators defined by the integrands and by cores of those functions.
