Effective kink-kink interaction in a one-dimensional model mediated by phonon exchange
1994
The general 1D double-well model with anharmonic interaction is considered in the displacive limit. Expansion of the Hamiltonian around a multikink state results in a phonon-kink Hamiltonian. It is shown that at rather low temperatures and short wave lengths the phonon-kink interaction can be treated in Born approximation, leading to a decomposition of the multikink-phonon Hamiltionian. Elimination of the phonons results in an effective potential for the kink-kink interaction, which corresponds to the one-dimensional analog of the RKKY interaction. This long-range interaction is inherent only for models with anharmonic on-site potentials and not in case of a double-parabola model.
Evolution-Oriented User-Centric Data Warehouse
2011
Data warehouses tend to evolve, because of changes in data sources and business requirements of users. All these kinds of changes must be properly handled, therefore, data warehouse development is never-ending process. In this paper we propose the evolution-oriented user-centric data warehouse design, which on the one hand allows to manage data warehouse evolution automatically or semi-automatically, and on the other hand it provides users with the understandable, easy and transparent data analysis possibilities. The proposed approach supports versions of data warehouse schemata and data semantics.
Measuring music-induced emotion: A comparison of emotion models, personality biases, and intensity of experiences
2011
Most previous studies investigating music-induced emotions have applied emotion models developed in other fields to the domain of music. The aim of this study was to compare the applicability of music-specific and general emotion models – namely the Geneva Emotional Music Scale (GEMS), and the discrete and dimensional emotion models – in the assessment of music-induced emotions. A related aim was to explore the role of individual difference variables (such as personality and mood) in music-induced emotions, and to discover whether some emotion models reflect these individual differences more strongly than others. One hundred and forty-eight participants listened to 16 film music excerpts a…
Los fenómenos disociativos: una revisión conceptual
2003
En el presente trabajo se lleva a cabo una revisión del concepto de disociación y de los fenómenos asociados, haciendo un recorrido desde las posturas clásicas, como la de Janet, hasta los planteamientos que actualmente se centran en el estudio de los fenómenos disociativos. Se aborda, además el planteamiento acerca de la existencia de un continuo de experiencias disociativas, o modelo dimensional, que actualmente se formula conjugado con un modelo tipológico, y se hace una breve revisión de los estudios que se han centrado en las relaciones entre la variable disociación y ciertas variables que tradicionalmente han sido asociadas a este concepto, como la hipnotizabilidad o la represión. Fin…
Elaboration of a Critical Paradigm for Interpreting Modern Architecture: The Almost Intangible Essence of Luigi Moretti's Casa del Balilla at Trecate
2021
Modern architecture is not, from a lexical point of view, uniquely definable. The heterogeneity of the twentieth century heritage is therefore a collective wealth that should be protected from the risk of falling into oblivion. In order to avoid this, it could prove fundamental to establish a process of the knowledge of these assets. This should not, however, result in a simple and passive recording of architectural facts: a deep understanding of the complexity of modern architecture, which has as its objective the protection of buildings, could be obtained, for example, through a real and proper decoding of signs, conducted by a critical use of the metalanguage most congenial to the archit…
Next-generation three-dimensional modelling software for personalized surgery decision-making in perihilar cholangiocarcinoma: multicentre study
2021
Next-generation three-dimensional modelling software for personalized surgery allows spatially accurate depiction of the hepatic and vasculature anatomy based on the complexity and individual variation in each patient, and could facilitate decision-making about preoperative strategy in perihilar cholangiocarcinoma.
Two-dimensional model colloids and nano wires: phase transitions, effects of external potentials and quantum effects
2005
Abstract Quantum effects, structures and phase transitions in Nano-systems have been analyzed. An overview is given on the results of our computations on structural and elastic properties of model colloids, on phase transitions of model colloids in external fields, and on structural and electronic properties of stretched atomic wires.
Immagine urbana e qualità dello spazio nel rilievo tridimensionale di due borgate storiche palermitane
2014
Lo sviluppo dei software di rappresentazione digitale ha comportato una significativa evo- luzione dei modelli rappresentativi, aprendo contemporaneamente la strada a nuove que- stioni di natura non soltanto operativa, ma anche sostanziale. L’assenza di scala di riduzione, la tridimensionalità in “real time”, l’immersività e l’interattività dello spazio virtuale sono infatti ben più di semplici novità strumentali: si pongono come nuovi codici, introducono una visibilità simultanea e onnicomprensiva, definiscono il modello che si viene a elaborare come un “alter” dello spazio indagato, autonomo e parallelo alla realtà stessa, ben più insomma del ruolo di “model- lo” del reale al quale la rap…
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
Static and dynamic policies with RFID for the scheduling of retrieval and storage warehouse operations
2013
Warehouses are essential components of logistics and supply chains. The performance of warehouse operations significantly affects the efficiency of the whole chain it belongs to. Radio frequency identification (RFID) is an emerging technology capable of providing real-time information about the location and properties of tagged object(s), such as people, equipment or products. The objective of this article is threefold, to propose and compare different offline and online policies for the scheduling of warehouse operations, to design a tool that allows the decision maker to compare policies and environments without putting them into practice, and to study the benefits that can be obtained if…
