Using a neural network for qualitative and quantitative predictions of weld integrity in solid bonding dominated processes
2014
Solid-state bonding occurs in several manufacturing processes, as Friction Stir Welding, Porthole Die Extrusion and Roll Bonding. Proper conditions of pressure, temperature, strain and strain rate are needed in order to get effective bonding in the final component. In the paper, a neural network is set up, trained and used to predict the bonding occurrence starting from the results of specific numerical models developed for each process. The Plata-Piwnik criterion was used in order to define a quantitative parameter taking into account the effectiveness of the bonding. Excellent predictive capability of the network is obtained for each process.
Analytical bonding criteria for joint integrity prediction in friction stir welding of aluminum alloys
2014
Abstract In this study, two bonding criteria, previously used for porthole die extrusion, are applied to FSW starting from the local value of the main field variables calculated through a specifically developed 3D numerical model of the process. Their applicability and effectiveness have been assessed through an experimental and numerical campaign carried out with the main process parameters varying in a wide range. The pressure–time–flow criterion was demonstrated to be better suited for FSW processes when large welding speed is used.

This record contains data related to article “Chronic inflammatory demyelinating polyradiculoneuropathy: can a diagnosis be made in patients not fulfilling electrodiagnostic criteria?" Abstract Background and purpose: The aim was to identify the clinical and diagnostic investigations that may help to support a diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) in patients not fulfilling the European Federation of Neurological Societies and Peripheral Nerve Society (EFNS/PNS) electrodiagnostic criteria. Methods: The data from patients with a clinical diagnosis of CIDP included in a national database were retrospectively reviewed. Results: In all, 535 p…
Kompensācija cietušajam par nodarīto kaitējumu kriminālprocesā
2015
Mūsdienās aizvien ir aktuāla morālā kaitējuma kompensācijas noteikšana kriminālprocesā, it sevišķi tāpēc, ka morālam kaitējumam nepastāv precīzi nosakāms naudas ekvivalents. Darba mērķis ir izveidot universālu, ilgspējīgu morālā kaitējuma noteikšanas koncepciju, skaidri noteikt kritērijus, kuri tiesnešiem jāņem vērā, lemjot par kaitējuma kompensācijas apmēru, turklāt izpētīt arī praktiskos jautājumus, kas saistās ar kompensācijas pieteikšanu. Pētījuma rezultātā izstrādāta ilgspējīga morālā kaitējuma koncepcija, kurā noteikti rekomendējoši, taču aptuveni kompensācijas piešķiršanas apmēri, kā arī piedāvāti vairāki Kriminālprocesa likuma grozījumi.
La catena del valore nelle organizzazioni produttive di servizi. Il capitale sociale della città
2005
The urban unity-difference, formed of the social community interacting with the human, natural and constructed environments, produces private and social values or benefits. Interactions among the "services supplying urban firm" and the social, economic and natural environments produce value flows that dinamically form and exchange in the value chain. The New Economics approach is used to analyze the functioning principles of such a kind of value chain. Moreover, the application of a multicriterial operational model for the valuation of variations of social capital produced by every kind of private o public "firm-market system" is outlined. The subject is rilevant: in the public decisional c…

Public procurement: current situation and points of improvement
2015
[ES] La construcción pública ha sido, es y será uno de los pilares fundamentales del sector construcción español, si bien la actual situación de crisis económica y la reducción de la inversión pública en nuevas infraestructuras ha generado un descenso de actividad hasta niveles similares a los años noventa. El retorno a índices de actividad más elevados no solo se conseguirá con la recuperación de la economía del país, sino que será necesario realizar ciertas mejoras en los procesos de licitación con objeto de conseguir una mayor funcionalidad y flexibilidad en la contratación pública de obras.

QUESTIONI IN TEMA DI SINDACABILITà DEGLI ATTI DI NOMINA DELLE AUTORITA' INDIPENDENTI
2009
Nel lavoro si procede alla disamina dei profili problematici attinenti alle procedure di nomina dei membri delle Autorità indipendenti e, di conseguenza, della natura dei requisiti soggettivi che devono essere posseduti e riscontrati nei candidati a titolari degli organi di vertice, al fine specifico di verificare le possibilità e i limiti di sindacabilità di tali atti da parte del potere giudiziario. Nel saggio, innanzitutto, si sostiene la tesi che il procedimento di nomina rappresenta uno dei punti salienti dell’indipendenza delle Autorità, anche se, nel corso del lavoro, si dimostra anche che tale strumento non sia l’unico in grado di garantire la impermeabilità dell’Autorità alle solle…
