From laser scanning to finite element analysis of complex buildings by using a semi-automatic procedure - Castellazzi, Giovanni; D'Altri, Antonio Maria; Bitelli, Gabriele; Selvaggi, Ilenia; Lambertini, Alessandro
In this paper a new semi-automatic procedure to transform three-dimensional point clouds of complex objects to three-dimensional finite element models is presented and validated. The procedure (CLOUD2FEM) conceives the point cloud as a stacking of point sections. The complexity of the clouds is arbitrary since the procedure is designed for terrestrial laser scanner surveys applied to buildings with irregular geometry, such as historical buildings. The proposed method allows to always produce a filled three-dimensional model ready to use for structural analysis purpose. A comparison analysis with a CAD based model is carried out on a historical building damaged by a...
Sales online of Health Products: Economical and Administrative Perspective - Vagnozzi, Ercole
The continuing decline in the pharmaceutical expenditure deduction, the increasing fees paid by pharmacies in favor of the NHS and the crisis that reduces the spending power of the citizen, triggered a huge drop in the profitability of the Italian pharmacies. However the crisis can also be positive because it forces the companies to deploy all the resources needed to invert the situation, changing certain vicious behaviors in favor of virtuous ones. But if on the one hand, it is the single pharmacist who should implement corrective measures, on the other hand some problems must be solved by the entire...
Retail Distribution of OTC Pharmaceuticals: Growth Rate Hypothesis - Vagnozzi, Ercole
Just as the internet has transformed how we communicate and share, it is now transforming how we work, and of course, how we shop and particularly, in the healthcare sector, this theme is becoming prominent. Starting from two observed events: 1. the growing market demand of healthy products toward internet channels and 2. the importance to safely regulate that market, to prevent the danger naturally associated to the drugs sale on the net, the article has been drawn up to analyse the future Italian scenario where the OTC pharmaceuticals will be traded online (Vagnozzi, 2015) as sustained by the new...
E-commerce adoption in the pharmacy retailing - Vagnozzi, Ercole
The sale online of pharmaceuticals is a recent issue in Italy and still under evaluation by the government because of its sensitive implications for the health as well as the unavoidable consequences it might have in the pharmaceutical market. It will, first, be presented an excursus on the change sustained by the pharmacy over the last years, generated by legislative developments which obliged the pharmacy itself to reconsider its role. The brief normative overview has the objective to describe the Italian-specific pharmaceutical context; from the Bersani Decree, to Law Monti, ending with the recent European Directive 2011/62 UE, which regulates...
Comparing persistence diagrams through complex vectors - Di Fabio, Barbara; Ferri, Massimo
The natural pseudo-distance of spaces endowed with filtering functions is precious for shape classification and retrieval; its optimal estimate coming from persistence diagrams is the bottleneck distance, which unfortunately suffers from combinatorial explosion. A possible algebraic representation of persistence diagrams is offered by complex polynomials; since far polynomials represent far persistence diagrams, a fast comparison of the coefficient vectors can reduce the size of the database to be classified by the bottleneck distance. This article explores experimentally three transformations from diagrams to polynomials and three distances between the complex vectors of coefficients.
Thermoelectric cells cogeneration from biomass power plant: literature review - Bianchini, Augusto; Donini, Filippo; Pellegrini, Marco
Thermoelectric cells convert directly heat into electricity but, due to the low conversion efficiency (up to 5%), most applications are in waste heat recovery. Another promising application is in biomass boiler. In this case, the installation of thermoelectric modules converts a biomass boiler into a cogeneration system, where the aim of the integration is not the electricity production for external power supply, but the realization of a stand-alone biomass power plant which could match the customer needs in isolated places. This review is focused on the recent research papers in thermoelectric biomass cogeneration.
Combining persistent homology and invariance groups for shape comparison - Frosini, Patrizio; Jablonski, Grzegorz
In many applications concerning the comparison of data expressed by R^m-valued functions defined on a topological space X, the invariance with respect to a given group G of self-homeomorphisms of X is required. While persistent homology is quite efficient in the topological and qualitative comparison of this kind of data when the invariance group G is the group Homeo(X) of all self-
homeomorphisms of X, this theory is not tailored to manage the case in which G is a proper subgroup of Homeo(X), and its invariance appears too general for several tasks. This paper proposes a way to adapt persistent homology...
Il contratto di trasferimento di tecnologia nel diritto Cinese. - Carpi, Angela
Il trasferimento di tecnologia è uno dei pilastri dello sviluppo economico cinese contemporaneo. Tale trasferimento è soggetto ad un quadro normativo specifico e complesso che è essenziale conoscere se si intende intraprendere una attività di import/export con il gigante asiatico.
Il presente studio, seppure brevemente, si propone di ricostruire la normativa cinese in materia di contratti per il trasferimento di tecnologia.
Osservatorio sulla qualità edilizia in Romagna - Guardigli, Luca; Barbolini, Fausto
L’idea di proporre un osservatorio sulla qualità edilizia è nata dall’intento di fotografare in modo critico quello che viene costruito in un certo lasso di tempo all’interno di un determinato ambito territoriale, estrapolando le problematiche in atto e le tendenze per il prossimo futuro. Nell’attuale rapporto sempre più dicotomico tra teoria e pratica del progetto, l’obiettivo è stato quello di mettere in evidenza lo stato dell’arte della pratica progettuale, che si concretizza nel costruire contemporaneo, riferita ad alcune tipologie edilizie e perimetrate volutamente in un preciso ambito territoriale di riferimento.
Lo studio condotto per il territorio romagnolo ha analizzato più di...
The edit distance for Reeb graphs of surfaces - Di Fabio, Barbara; Landi, Claudia
Reeb graphs are structural descriptors that capture shape
properties of a topological space from the perspective of a chosen function. In this work we define a combinatorial metric for Reeb graphs of orientable surfaces in terms of the cost necessary to transform one graph into another by edit operations. The main contributions of this paper are the stability property and the optimality of this edit distance. More precisely, the stability result states that changes in the functions, measured by the maximum norm, imply not greater changes in the corresponding Reeb
graphs, measured by the edit distance. The optimality result states that our...
Reeb graphs of surfaces are stable under function perturbations - Di Fabio, Barbara; Landi, Claudia
Reeb graphs are combinatorial signatures that capture shape
properties from the perspective of a chosen function. One of the
most important questions is whether Reeb graphs are robust against
function perturbations that may occur because of noise and
approximation errors in the data acquisition process. In this work
we tackle the problem of stability providing an editing distance
between Reeb graphs of orientable surfaces in terms of the cost
necessary to transform one graph into another by edit operations.
Our main result is that changes in the functions, measured by the
maximum norm, imply not greater changes in this distance, yielding
the stability property under function perturbations.
Social capital, institutions and policy making - Savioli, Marco
Economic processes, consisting of interactions between human beings, exploit the social capital of persons endowed with specific culture and identities. The role of institutions and policy makers is to build positive social capital and exploit it to reach their objectives. However, social capital is elusive and has several dimensions by which to interpret its multifaceted functions in economics and society. We cannot forget, furthermore, that social capital sometimes is undesirable for society, for instance when used for unethical uses. Even so, it is widely accepted that social capital has stable and positive effects.
Observation of abundant heat production from a reactor device and of isotopic changes in the fuel - Levi, Giuseppe; Evelyn, Foschi; Bo, Hoistad; Roland, Pettesson; Lars, Tegnér; Hanno, Essén
New results are presented from an extended experimental investigation of anomalous heat production in a special type of
reactor tube operating at high temperatures. The reactor, named E-Cat, is charged with a small amount of hydrogen-loaded
nickel powder plus some additives, mainly Lithium. The reaction is primarily initiated by heat from resistor coils around the
reactor tube. Measurements of the radiated power from the reactor were performed with high-resolution thermal imaging
cameras. The measurements of electrical power input were performed with a large bandwidth three-phase power analyzer.
Data were collected during 32 days of running in March 2014. The reactor operating...

Résumé. Musiciennes de terre cuite du sanctuaire de Fontana Calda (Sicile). Dans les années 50 on a mis au jour dans le sanctuaire de Fontana Calda (Sicile centrale) un dépôt constitué de centaines de figurines de joueurs d’aulos, de tympanon, de cymbales, de harpe, ainsi que des groupes de joueurs d’aulos et de tympanon ; elles datent d’entre la fin du VIe s. et le début du IIIe s. Des figurines comparables ont été retrouvées sur de nombreux autres sites de Sicile et en particulier dans des sanctuaires qui étaient comme celui de Fontana Calda consacrés à des divinités chthoniennes....
Sewage sludge: characteristics and recovery options - Bonfiglioli, Luca; Bianchini, Augusto; Pellegrini, Marco; Saccani, Cesare
In this paper, an overview on sewage sludge characteristics and recovery routes is presented. Starting from an analysis of typical sewage sludge characteristics as found in literature, the most promising disposal options are presented. A focus on incinerated sewage sludge ash (ISSA) follows. Most of the authors agree on considering pyrolysis and gasification as the most viable treatments for sludge in the near future. For this reason, the last two chapters offer a brief description of these two processes and their products.
