Modelling mode choice for freight transport using advanced choice experiments
2015
Abstract In this paper we use advanced choice modelling techniques to analyse demand for freight transport in a context of modal choice. To this end, a stated preference (SP) survey was conducted in order to estimate freight shipper preferences for the main attributes that define the service offered by the different transport modes. From a methodological point of view, we focus on two critical issues in the construction of efficient choice experiments. Firstly, in obtaining good quality prior information about the parameters; and secondly, in the improved quality of the experimental data by tailoring a specific efficient design for every respondent in the sample. With these data, different …
Polynomial method to study the entanglement of pure N-qubit states
2009
We present a mapping which associates pure N-qubit states with a polynomial. The roots of the polynomial characterize the state completely. Using the properties of the polynomial we construct a way to determine the separability and the number of unentangled qubits of pure N-qubit states.

On the Quest for Defining Organisational Plasticity: A Community Modelling Experiment
2020
PurposeThis viewpoint article is concerned with an attempt to advance organisational plasticity (OP) modelling concepts by using a novel community modelling framework (PhiloLab) from the social simulation community to drive the process of idea generation. In addition, the authors want to feed back their experience with PhiloLab as they believe that this way of idea generation could also be of interest to the wider evidence-based human resource management (EBHRM) community.Design/methodology/approachThe authors used some workshop sessions to brainstorm new conceptual ideas in a structured and efficient way with a multidisciplinary group of 14 (mainly academic) participants using PhiloLab. Th…

Una mostra sui disegni di architettura siciliani del XVII e del XVIII secolo
2010
La mostra - e il relativo catalogo - dal titolo "Ecclesia Triumphans. Architetture del Barocco siciliano attraverso i disegni di progetto XVII-XVIII secolo" (Caltanissetta, 2009) a cura di M.R. Nobile, S. Rizzo, D. Sutera, si pone come momento di confluenza di due diversi percorsi di ricerca intrapresi da anni da Marco Nobile e dal suo gruppo di ricerca: lo studio dell'architettura chiesastica siciliana d'età moderna, con particolare riferimento al dibattito sulle chiesa madri tra XVII e XVIII secolo, e la perlustrazione sistematica delle testimonianze progettuali superstiti, conservate nei diversi archivi, collezioni proivate ed enti pubblici. La mostra di Caltanissetta ha infatti raccolto…
Antibacterial drug release from a biphasic gel system: Mathematical modelling
2019
Bacterial infections represent an important drawback in the orthopaedic field, as they can develop either immediately after surgery procedures or after some years. Specifically, in case of implants, they are alleged to be troublesome as their elimination often compels a surgical removal of the infected implant. A possible solution strategy could involve a local coating of the implant by an antibacterial system, which requires to be easily applicable, biocompatible and able to provide the desired release kinetics for the selected antibacterial drug. Thus, this work focusses on a biphasic system made up by a thermo-reversible gel matrix (Poloxamer 407/water system) hosting a dispersed phase (…
A multilevel object-oriented modelling methodology for physiologically-based pharmacokinetics (PBPK): Evaluation with a semi-mechanistic pharmacokine…
2019
Abstract Background and objective The aims of this study are (i) to assess the predictive reliability of the physiologically based software PhysPK versus the well-known population approach software NONMEM for the cited semi-mechanistic PK model, (ii) to determine whether these modelling approaches are interchangeable and (iii) to compare acausal with causal modelling approaches in the framework of semi-mechanistic PK models. Methods A semi-mechanistic model was proposed, which assumed oral administration of a solid dosage form with a peripheral compartment and two active metabolites. The model incorporates intestinal transit, dissolution limited by solubility, variable efflux transporter ex…
