Digital storytelling teaching robotics basics
Michele Scandola,Paolo Fiorini
Themes in Science and Technology Education , 2013,
Abstract: Digital Storytelling (DST) is a powerful tool for teaching complex concepts. DSTs are typically used in the humanities but several papers have shown that they are also a wonderful tool for the sciences because they are more involving, contextualized and can easily lead to deeper understanding. In the classical use of DST the story is thecontent, while the digital medium is the way of telling it. Our approach is slightly different: the story is not the content but a glue for the main contents, while the digital medium remains the way to tell the story. We propose the use of DST as a means to teach surgeons the basics of robotic surgery, by using a story that should be involving forthem, i.e. a surgical operation, within which we will illustrate specific concepts onrobotics in surgery.
The Evolution of Defense in Depth Approach: A Cross Sectorial Analysis  [PDF]
Lorenzo Chierici, Gian Luigi Fiorini, Stefano La Rovere, Paolo Vestrucci
Open Journal of Safety Science and Technology (OJSST) , 2016, DOI: 10.4236/ojsst.2016.62004
Abstract: The Defense in Depth (DiD) is a classical defensive concept currently applied to a variety of technical fields, including nuclear (where this concept is widely applied) and chemical industry, Information and Communication Technology (ICT), transport, and many others. It deals with slowdown of the progression of an “attack” against a “target” by using multiple and independent levels of protection (or lines of defense), designed to compensate for the failure of one or more defenses, ensuring that the risks are kept acceptable. Concerning the current practices for the DiD implementation and the rationale for its evolution, there is a shared recognition that the reinforcement of DiD is the key to improve the safety of future installations for all types of technologies and industries. Within this context, the results of Probabilistic Safety Assessment (PSA) play a key role in the demonstration of both the robustness of the design and safety, supporting the verification that the DiD principles are correctly implemented. A key issue, still open, is related to the link that must be put in place to provide the DiD probabilistic success criteria through PSA insights. After an analysis of DiD evolution in time and DiD application to different industrial fields, this paper deals with the key issue, still open, relevant to the link that must be put in place to provide the DiD probabilistic success criteria through PSA insights. Practical proposals outlined point out the open questions.
Exergy-based Comparative Assessment of “Zero CO2 Emission” Coal Gasification Processes Feeding H2 –Fueled Power Plants
Valentina Amati,Enrico Sciubba,Paolo Fiorini
International Journal of Thermodynamics , 2006, DOI: 10.5541/ijot.163
Abstract: A modular Process Simulator, CAMEL , developed by the University of Roma 1, has been applied to analyse a series of “zero emissions” high efficiency cycles. This paper compares three different cycles integrated with CO2 separation technologies based on chemical or physical absorption upstream of the combustion process: pure hydrogen is burnt in presence of pure oxygen to produce superheated steam. All solutions are based on nonconventional plant configurations: two of them are H2/O2 cycles and the third one is the so called ZECOTECH cycle. The main features of all three configurations are presented and their thermodynamic cycles are simulated in order to perform an exergy analysis.
Dal castrum altomedievale al restauro settecentesco: storia e archeologia del castello di Sorrivoli (Roncofreddo - FC)
Fiorini, Andrea
Arqueología de la Arquitectura , 2011,
Abstract: The methods and tools used to determine the history of construction and building techniques of the castle of Sorrivoli (Roncofreddo - FC) are here described. This is a research project carried out within a study coordinated by the teaching of Medieval Archaeology (University of Bologna), which has the purpose of conducting a census of all the medieval castles in Romagna. There is certain news from the tenth century concerning the castle to be studied. However, the investigations have shown that the standing preserved structures must be dated from the fourteenth century onwards. The system of photogrammetric survey of the walls and the technique of threedimensional modelling of the structures are here described. An extended part of this paper is also devoted to results of stratigraphic, typological, geological, metrological and comparative mensio-cronological analysis. No disponible
Three-dimensional recording in the archaeological excavation at the Bronze Age settlement of Mursia, Pantelleria. LA DOCUMENTAZIONE TRIDIMENSIONALE DELLO SCAVO ARCHEOLOGICO NELL’ABITATO DELL’ETà DEL BRONZO DI MURSIA, PANTELLERIA (TP)
Andrea Fiorini
IpoTESI di Preistoria , 2010,
Abstract: The purpose of this paper is to describe methods of documentation and detection techniques used on the archaeological site of Mursia (Pantelleria, TP) in order to build three-dimensional models of a hut and a stone mortar. The software measures three-dimensional coordinates of a finite set of points on the object using two photographs taken from different positions (stereo pairs). In particular, we explore some technical aspects of data processing like quickness, measurement accuracy, information content of record and equipments cost. In questo contributo si descrivono i metodi e gli strumenti di rilievo impiegati nel sito archeologico di Mursia (Pantelleria – TP) per ottenere i modelli tridimensionali di una capanna e di un mortaio litico. Il software misura sull’oggetto le coordinate tridimensionali di un set finito di punti utilizzando due foto riprese da posizioni differenti (“stereocoppia”). Si approfondiscono, in particolare, alcuni aspetti di questa tecnica di rilievo: la rapidità (del procedimento), l’accuratezza (della misura), il contenuto informativo (della registrazione) e il costo (degli strumenti).
Nonsingular Promises from Born-Infeld Gravity
Franco Fiorini
Physics , 2013,
Abstract: Born-Infeld determinantal gravity formulated in Weitzenbock spacetime is discussed in the context of Friedmann-Robertson-Walker (FRW) cosmologies. It is shown how the standard model big bang singularity is absent in certain spatially flat FRW spacetimes, where the high energy regime is characterized by a de Sitter inflationary stage of geometrical character, i.e., without the presence of the inflaton field. This taming of the initial singularity is also achieved for some spatially curved FRW manifolds where the singularity is replaced by a de Sitter stage or a big bounce of the scale factor depending on certain combinations of free parameters appearing in the action. Unlike other Born-Infeld-like theories in vogue, the one here presented is also capable of deforming vacuum general relativistic solutions.
Top-Quark Physics Results From LHC
Luca Fiorini
Physics , 2012,
Abstract: The top-quark is a fundamental element of the physics program at the Large Hadron Collider (LHC). We review the current status of the top-quark measurements performed by ATLAS and CMS experiments in pp collisions at sqrt(s)=7 TeV by presenting the recent results of the top-quark production rates, top mass measurements and additional top quark properties. We will also describe the recent searches for physics beyond the Standard Model in the top-quark sector.
Secretion of Epstein-Barr Virus-encoded BARF1 oncoprotein from latently infected B cells
Sylvie Fiorini, Tadamasa Ooka
Virology Journal , 2008, DOI: 10.1186/1743-422x-5-70
Abstract: Epstein-Barr virus (EBV) is tightly associated with divers human cancers, in particular nasopharyngeal and gastric carcinomas, lymphoma induced in Aids patient, Hodgkin's lymphoma and endemic Burkitt's lymphoma [1]. EBV immortalises primary simian and human B-lymphocytes [1,2] as well as epithelial cells in vitro [3,4]. EBV infection is latent in B cells and classified in three types: Type I, Type II and Type III. Type I is common to lymphomas and express very limited viral protein, mainly EBNA1, EBERs and BARF0. Type II express EBNA1, LMP1, EBERS, BARF0 and LMP2. Type III express several viral proteins like EBV-encoded nuclear antigens (EBNA1, EBNA2, EBNA3A, 3B and 3C), LMP1, LMP2A, LMP2B, BARF0 and EBERs [5]. Nasopharyngeal carcinoma belongs to Type II. Primary epithelial cells immortalized in vitro by EBV expressed EBNA1, EBERs, LMP2A and BARF1[3,4,6], thus belong to type II infection except for the absence of LMP1 expression.Among about 90 genes encoded by EBV genome, two oncogenes, LMP1 and BARF1, are known to induce a malignant transformation in established rodent fibroblasts [7,8]. BARF1 was considered so far as an early gene. However among the viral lytic proteins, only BARF1 was expressed consistently and at high levels in NPC [9-11] and also in EBV-associated GC carcinoma as well as in EBV-immortalized epithelial cells in vitro [3,6,12]. In these cells, the expression of LMP1 and lytic genes was negative. BARF1 expression was also detected in B lymphoma frequent in Malawi [13] and in nasal NK/T-cell lymphoma [14]. Its expression is therefore not limited to epithelial cells, but also in B cells.BARF1 has a malignant transforming activity in rodent fibroblasts and in human EBV-negative B cells [8,15]. Its transforming and Bcl2 activating domain was demonstrated between 21st to 56th amino acid sequences by deletion mutants [15]. BARF1 has also immortalizing activity on primary primate epithelial cells [16]. Secreted BARF1 protein (called p29) purified from 29

On Born-Infeld Gravity in Weitzenbock spacetime
Rafael Ferraro,Franco Fiorini
Physics , 2008, DOI: 10.1103/PhysRevD.78.124019
Abstract: Using the Teleparallel Equivalent of General Relativity formulated in Weitzenb\"{o}ck spacetime, we thoroughly explore a kind of Born-Infeld regular gravity leading to second order field equations for the vielbein components. We explicitly solve the equations of motion for two examples: the extended BTZ black hole, which results to exist even if the cosmological constant is positive, and a cosmological model with matter, where the scale factor results to be well behaved, giving so a singularity-free solution.
