Does ns2 Really Simulate MPLS Networks?
2008
Multi Protocol Label Switching (MPLS) is being used in many corporate networks and public infrastructures and as a backbone technology of many Autonomous Systems. Because of its importance, what is needed is to find out simulators able to simulate MPLS networks whose results reflect the real environment as much as possible. In this article, we will show real measurements from the Railway Infrastructure Administrator (ADIF, the Spanish railway infrastructure manager) MPLS network and we will compare them with the results obtained by the freeware simulator ns2. We will check the level of reliability provided by the simulator and we will know under which parameters its results will be similar …
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
Contratto di rete e diritto antitrust
2017
La disciplina del contratto di rete (“c.d.r.”) – introdotta nel nostro ordinamento giuridico dalla l. 9 aprile 2009, n. 33 (di conversione del d.l. 10 febbraio 2009, n. 5, c.d. Decreto incentivi), e poi a più riprese modificata in modo sostanziale – ha sin dalla sua emanazione suscitato molteplici dubbi interpretativi ed incisive critiche, per lo più determinati da problemi d’inquadramento sistematico e dalla lacunosità del dettato normativo. La dottrina più incline a manifestare il proprio favore verso il nuovo istituto contrattuale, comunque, ne ha sovente evidenziato l’unicità nel panorama europeo, tale da conferire al legislatore italiano (una volta tanto) il ruolo di precursore nell’el…
Warum ist Pränataldiagnostik in der Diskussion? Eine Einführung
2017
Prenatal diagnosis has been a subject of intense discussion since it became technically achievable. This is because the results it provides can dramatically change the attitude of mothers towards their unborn children, and can lead to considerable social pressure to abort the child. These undesirable effects might come as a surprise, given that prenatal testing was primarily intended to allow better care for infants waiting to be born. The possible risks of invasive procedures and the only statistical evidence of results are the factors most responsible for the ambivalent attitudes that surround prenatal diagnosis. Another significant factor is the discrepancy between the general availabili…
SHEAR RESISTANCE OF R/C BEAMS PROVIDED WITH DIFFERENTLY-INCLINED TRANSVERSE REINFORCEMENT
2012
The model for the evaluation of shear resistance of reinforced concrete member provided with transverse web reinforcement, derived by Nielsen (1999) on the basis of the variable inclination stress field approach, is generalized here to predict the shear strength of r.c. beams equipped with two sets of differently-inclined transversal web reinforcement and longitudinal skin reinforcement. Numerical analyses emphasize the efficiency of double inclined web transverse reinforcement in providing shear strength to beams.
Questions and controversies in the study of time-varying functional connectivity in resting fMRI.
2020
The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and the relationship between neural dynamics and cognition in health and disease. The possibility of studying these dynamics through careful analysis of neuroimaging data has catalyzed substantial interest in methods that estimate time-resolved fluctuations in functional connectivity (often referred to as “dynamic” or time-varying functional connectivity; TVFC). At the same time, debates have emerged regarding the application of TVFC analyses to re…
Piogge interminabili rese in forte calo

Il clima avverso è stato l'elemento chiave dell'annata, con un decremento delle produzioni fino al 30%. E il colpo di grazia potrebbe arrivare dalle micotossine.
Competenze educative interculturali. Saperi e pratiche nella rete di protezione dei migranti.
2022
Il volume è strutturato in due parti. Nella prima, di carattere teorico, si analizza il complesso fenomeno migratorio e si affronta il tema della competenza interculturale nella riflessione pedagogica. Nella seconda parte del volume, dopo aver specificato il metodo di ricerca messo in atto per la raccolta dei dati sulle conoscenze e competenze interculturali dei professionisti educatori, e non solo, del settore dell’accoglienza, vengono presentati i risultati di due indagini scientifiche. L’obiettivo della ricerca è stato di elaborare un modello teorico e interattivo, con implicazioni pratiche, sulle conoscenze e competenze interculturali del professionista dell’accoglienza. Destinatari di …

Construction stages of cable-stayed bridges with composite deck
2012
A cable-stayed bridge is built by following a construction sequence of different subsequent stages that imply changes of the geometric configuration, restraints and consequently stress and strain patterns. A study is presented about stay stressing sequences in cable-stayed bridges with composite deck for the case of construction made by the cantilever method. Initial cable forces are found through partial elastic schemes of construction stages. Different stay stressing procedures are implemented and a comparison between them is proposed in order to evaluate the differences in terms of deformed shape and internal force distribution of the deck and the pylon. Results can be useful to give pra…
