Is the multiplicative anomaly relevant ?
Emilio Elizalde,Antonio Filippi,Luciano Vanzo,Sergio Zerbini
Physics , 1998,
Abstract: In a recent work, S. Dowker has shed doubt on a recipe used in computing the partition function for a matrix valued operator. This recipe, advocated by Benson, Bernstein and Dodelson, leads naturally to the so called multiplicative anomaly for the zeta-function regularized functional determinants. In this letter we present arguments in favour of the mentioned prescription, showing that it is the valid one in calculations involving the relativistic charged bosonic ideal gas in the framework of functional analysis.
Is the multiplicative anomaly dependent on the regularization ?
Emilio Elizalde,Antonio Filippi,Luciano Vanzo,Sergio Zerbini
Physics , 1998,
Abstract: In a recent work, T.S. Evans has claimed that the multiplicative anomaly associated with the zeta-function regularization of functional determinants is regularization dependent. We show that, if one makes use of consistent definitions, this is not the case and clarify some points in Evans' argument.
One-loop Effective Potential for a Fixed Charged Self-interacting Bosonic Model at Finite Temperature with its Related Multiplicative Anomaly
Emilio Elizalde,Antonio Filippi,Luciano Vanzo,Sergio Zerbini
Physics , 1997, DOI: 10.1103/PhysRevD.57.7430
Abstract: The one-loop partition function for a charged self-interacting Bose gas at finite temperature in D-dimensional spacetime is evaluated within a path integral approach making use of zeta-function regularization. For D even, a new additional vacuum term ---overlooked in all previous treatments and coming from the multiplicative anomaly related to functional determinants-- is found and its dependence on the mass and chemical potential is obtained. The presence of the new term is shown to be crucial for having the factorization invariance of the regularized partition function. In the non interacting case, the relativistic Bose-Einstein condensation is revisited. By means of a suitable charge renormalization, for D=4 the symmetry breaking phase is shown to be unaffected by the new term, which, however, gives actually rise to a non vanishing new contribution in the unbroken phase.
Feasibility Evaluation of Integrating UsabilityEngineering Issues in a Design for Multi-XCollaborative Framework  [PDF]
Stefano Filippi
Intelligent Information Management (IIM) , 2011, DOI: 10.4236/iim.2011.31004
Abstract: Design for manufacturing, design for assembly, and, in general, design for X, are methods helping an effective generation of industrial products. In parallel with the development of these methods, the research about usability engineering has generated many important results, both from the design, and the evaluation and testing points of view. The research described in this paper aims at evaluating the feasibility of the integration of two new usability methods, the design for innovative usability - DFIU -, and the integrated method for usability evaluation and testing - IMUET -, in an existing design for X named design guidelines collaborative framework - DGLs-CF -. Indeed, the DGLs-CF is a design for multi-X method, given that it covers both the manufacturing and the verification phases of the industrial product lifecycle. All these methods are currently under development by the author’s research group. To evaluate this feasibility, the first task of the research aims at describing and classifying the components of the three methods. Next, these components are semantically related to each other. Finally, the last activity verifies the compatibility between the components of the two usability methods and the data structures of the DGLs-CF to check the feasibility from the implementation point of view. The result of this research will consist of precise indications both for the development of a design for multi-X collaborative framework covering homogeneously the design, manufacturing, verification, and use phases of the industrial product lifecycle, and to be used as a reference for researchers interested in considering the integration of usability issues in their design tools, methods, and processes.
Using Rapid Prototyping Data to Enhance a Knowledge-Based Framework for Product Redesign  [PDF]
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.21001
Abstract: The particular characteristics of Rapid Prototyping technologies, both in terms of constrains and opportunities, often require the reconfiguration of the product model to obtain the best compliance with the product functionalities and performances. Within this field of research, a knowledge-based tool named Design GuideLines Collaborative Framework (DGLs-CF) was developed to support both the designers defining the product consistently with the manufacturing technologies and the manufacturers defining the building setup consistently with the product requirements. Present work is focused on enhancing the DGLs-CF knowledge base and on updating the DGLs-CF knowledge management by using the information gathered on some RP technologies. The added-value of this research is represented by an improvement in the Redesign/Reconfig- uration Package, the final result of the DGLs-CF adoption. This is a list of actions to be performed on the product model and on the process parameters to avoid the limitations of the technology and to exploit at best its opportunities.
Classification and Selection of Prototyping Activities for Interaction Design  [PDF]
Stefano Filippi, Daniela Barattin
Intelligent Information Management (IIM) , 2012, DOI: 10.4236/iim.2012.44022
Abstract: Because of the evolution of markets and technologies, prototyping concerns should be kept updated almost day by day. Moreover, user centered design moves the focus towards interaction issues. Prototyping activities matching such characteristics are already available, but they are not so diffused in the industrial domain. This is due to many reasons; an important one is that a rigorous classification of them is missing, as well as an effective helping tool for the selection of the best activities, given the design context. The research described in this paper aims at defining a new classification of prototyping activities, as well as at developing a selection algorithm to choose the best ones in an automatic way. These goals are pursued by defining a set of characteristics that allow describing accurately the prototyping activities. The resulting classification is made by five classes, based on eighteen characteristics. This classification is exploited by the first release of an algorithm for the selection of the best activities, chosen in order to satisfy design situations described thanks to a different set of eleven indices. Five experiences in the field have been used up to now as a starting point for validating the research outcomes.
Cristianismo y neoplatonismo en San Agustín: la crítica heideggeriana
Enfoques , 2010,
Abstract: heidegger believes to find in st. augustine, as in the case of paul, the expression of human existence as a historic fact, and of history as non objectively or available fate. this radical facticity of self belongs to the christian earliest form of experience that appears with strong clearness in st. augustine's confessions, particularly in book x. there are two relevant aspects that stand out in the heideggerian reading of confessions: for one, the phenomenology of self, and secondly, the understanding of dasein as time. however, in st. augustine, the dramatic finitude of existence is metaphysically and theologically transcended and grounded; while in heidegger's reflection, the finitude of human existence tends to close itself on its own limits.
Gelassenheit: el desapego como forma de vida en la mística eckhartiana
Enfoques , 2010,
Abstract: the notorious importance that eckhart gives to the detachment from things (gelassenheit) may suggest that the mystical german disdains active life. inversely, eckhart understands that the detachment in respect of the created being is perfectly compatible with the action and he even interprets the attitude of martha and mary towards jesus in a way which is opposite to the habitual.
Martin heidegger y la mística eckhartiana
Silvana Filippi
Invenio , 2003,
Abstract: Esta exposición intenta poner de manifiesto cierta semejanza entre algunos aspectos de la mística eckhartiana y el pensamiento del último Heidegger. El propio pensador alemán ha aludido en más de una ocasión al místico medieval, evidenciando en su lenguaje y en el modo de presentar su pensamiento acerca del ser, la influencia que aquella tradición ha ejercido sobre él. Considerando, además que Heidegger intentaba eludir el discurso argumentativo característico de la metafísica, no resulta difícil conjeturar que el lenguaje místico de Meister Eckhart pudo constituir hasta cierto punto, un estilo de expresión alternativo, aun cuando el objeto y el fin de ambos pensadores fuesen diferentes
