Radical innovation by theoretical abstraction - a challenge for the user-centred designer

2016

AbstractIt is generally accepted that scientific disciplines such as psychology, sociology, and anthropology contribute beneficially to design by providing understanding of users’ needs, experiences, and desires. Arguably, however, these disciplines have more to contribute, because they include theories and models that can be applied as design frames and principles. More specifically, goal-setting, visualization, thematization, and conceptual reconfiguration are general mechanisms through which theories translate into design contributions. Actualizing radical design solutions via these mechanisms is discussed: theories provide appropriate means of abstraction, which allows ‘distance’ from u…

New media and perennial problems in foreign language learning and teaching

2015

The book concerns the ways in which the new media shape communication along with educational expectations and practices in foreign language classrooms. Although foreign language learners have cheap and easy access to information and ways of communication, they also wrestle with problems that have always accompanied language learning. The focus of the book is two-fold. On the one hand, the authors demonstrate how using social networks, videoconferencing, mobile phones, wikis, and computer-mediated interaction contributes to the development of language skills, negotiated interaction, autonomy, and intercultural competence. On the other, they discuss “old” issues pertaining to the role of voca…

Entropy, transverse entropy and partitions of unity

1994

AbstractThe topological entropy of a transformation is expressed in terms of partitions of unity. The transverse entropy of a flow tangential to a foliation is defined and expresed in a similar way. The geometric entropy of a foliation of a Riemannian manifold is compared with the transverse entropy of its geodesic flow.

La committenza gesuitica e la pittura a Palermo tra XVI e XVIII secolo

Il presente lavoro di ricerca mira ad approfondire e arricchire, mediante nuove acquisizioni, lo studio in merito alle opere pittoriche di committenza gesuitica custodite presso le fondazioni palermitane dell’Ordine: chiesa del Gesù a Casa Professa, Collegio Massimo dei Gesuiti, chiesa di San Stanislao Kostka e chiesa di San Francesco Saverio. A queste si aggiungono i dipinti di committenza della Compagnia trasferiti presso altre sedi. Ulteriore intento è quello di organizzare in maniera più organica la trattazione delle commissioni artistiche dell’Ordine a Palermo, che si presentava dispersiva e frammentaria. Tra i risultati più significativi si annovera il ritrovamento di un ciclo di affr…

Educación XX1 : revista de la Facultad de Educación

2018

La siguiente investigación pretende analizar en qué medida los recursos educativos, en este caso los libros de texto, contribuyen a la alfabetización visual del alumnado de Educación Primaria en Ciencias Sociales. Este tipo de alfabetización es un aspecto fundamental en cualquier etapa educativa tal y como ha venido confirmando la investigación hasta fechas muy recientes. Para ello se han seleccionado los manuales más utilizados en un determinado espacio geográfico desde 2006 y se han analizado siguiendo un método de investigación que combina procedimientos cuantitativos (ex post-facto) y cualitativos (análisis mediante categorías conceptuales) aplicándolos sobre las actividades relacionada…

Figuration/Figure/Form

2020

It is still Weizsäcker to show that rather than a clear contrast (usually already referring to the names of Plato and Aristotle and to the competition between the concepts of eidos and morphé) it is a necessary correlation and a way through which the fundamental problem of unity of knowledge is placed.

Multistate active spaces from local CAS-SCF molecular orbitals: the photodissociation of HFCO as an example.

2005

A recently developed algorithm to generate localized molecular orbitals (LMO) is applied to the study of excited states along a photodissociation process. The LMOs allow for the selection of a consistent complete active space (CAS) for the simultaneous description of all the electronic states involved in a multistate process on the basis of simple chemical criteria. The local nature of the orbitals is used to label them in a unique way that does not depend on the molecular geometry. The selection of the electronic configurations of interest for the set of target states on only the basis of the dominant excitations required by the simplest configuration interaction (CI) descriptions for both…

Vertical spectrum of the C2H 2+ system. An open shell (SC)2-CAS-SDCI study

2003

The open shell (SC)(2)-CAS-SDCI method along with a basis set of atomic natural orbitals (ANO) has been applied for calculating the main ionization potentials of acetylene, as well as the manifold of excited states of the different symmetries up to 32 eV. In this method, the single and double excitations of a CAS space are generated and the corresponding CI matrix is corrected by means of the (SC)(2) procedure that cancels the size-extensivity error and adds some high order contributions. The mean absolute error for the outer-valence X (2)Pi(u)(1pi(u) (-1)), A (2)Sigma(g) (+)(3sigma(g) (-1)), and B (2)Sigma(u) (+)(2sigma(u) (-1)) states, and the inner-valence C (2)Sigma(g) (+)(2sigma(g) (-1…

Shuttling-Based Trapped-Ion Quantum Information Processing

2020

Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route toward realizing scalable quantum processing nodes. Establishing such nodes, providing sufficient functionality to represent a building block for emerging quantum technologies, e.g., a quantum computer or quantum repeater, remains a formidable technological challenge. In this review, the authors present a holistic view on such an architecture, including the relevant components, their characterization, and their impact on the overall system performance. The authors present a hardware architecture based on a uniform linear segmented multilayer trap, controlled by a custom-made fast multichannel arbitra…

Architectures and protocols for mobile computing applications: a reconfigurable approach

2004

This work deals with reconfigurable control functions and protocols for supporting mobile computing applications in heterogeneous wireless systems like cellular networks and WLANs. The control functions are implemented in a software module, named Reconfigurable Access module for MObile computiNg applications (RAMON), placed in mobile and/or base stations. RAMON operates on abstract models of the main communication functions of a wireless systems (e.g., transmission over the radio channel, coding end error recovery, capacity sharing and packet scheduling, handover, congestion control, etc.). RAMON algorithms are programmed with reference to the abstract models, independently of specific radi…
