Visualization of EDI messages

2003

Multi-organizational EDI message networks are complicated communication environments with various standards and technologies. The role of third party message exchange hubs has become more important and their tasks more difficult. Current development activities for supporting the utilization of XML in electronic commerce focuses on message standardization and specification of common business architectures, processes, and web practices. A need to visualize EDI messages in different contexts to human readers has received insufficient attention in ongoing activities. In this paper we discuss problems and approaches related to the visualization of EDI messages in XML format. An idea of a standar…

Algorithms for transforming an integral photography into a plenoptic picture

2013

We report a simple algorithm for transforming the set of elemental images captured with an integral-photography set up, into the set of micro-images ready to be projected into an integral-imaging monitor. The method is based in the transposing relation between an integral photography and a plenoptic picture. The reported technique permits to adapt the integral images to the resolution and size of the monitor.

The set of conjugacy class sizes of a finite group does not determine its solvability

2014

Abstract We find a pair of groups, one solvable and the other non-solvable, with the same set of conjugacy class sizes.

Formation of real, orthoscopic integral images by smart pixel mapping.

2005

Integral imaging systems are imaging devices that provide 3D images of 3D objects. When integral imaging systems work in their standard configuration the provided reconstructed images are pseudoscopic; that is, are reversed in depth. In this paper we present, for the first time we believe, a technique for formation of real, undistorted, orthoscopic integral images by direct pickup. The technique is based on a smart mapping of pixels of an elemental-images set. Simulated imaging experiments are presented to support our proposal.

Fully programmable display parameters in integral imaging by smart pseudoscopic-to-orthoscopic conversion

2011

Previously, we reported a digital technique for formation of real, non-distorted, orthoscopic integral images by direct pickup. However the technique was constrained to the case of symmetric image capture and display systems. Here, we report a more general algorithm which allows the pseudoscopic to orthoscopic transformation with full control over the display parameters so that one can generates a set of synthetic elemental images that suits the characteristics of the Integral-Imaging monitor and permits control over the depth and size of the reconstructed 3D scene.

A High Level Language for Pyramidal Architectures

1986

In the paper are described the syntax and some implementation features of a high level language for pyramidal architectures called Pyramid B Language (PCL). The language is an extension of the B and include data type, set of instructions and builtin functions oriented to the pyramidal architectures. Some notes on the implementation for the PAPIA machine are also given.

ARTIFICIAL STONE IN ARCHITECTURE: NEW TECHNIQUES OF INTERVENTION IN THE UTVEGGIO CASTLE IN PALERMO

2011

The development of new techniques and instruments for use in the field of the preservation, conservation and valorisation of Cultural Heritage is in continuous growth. This is evident in the many valuable scientific and technological improvements being implemented through projects financed by research institutions, universities and private companies. To make this renewed progress effective however, it is necessary to promote the creation of interdisciplinary research teams with different skills, to carry out new experiments and to define new methodologies and protocols.

Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento

2019

Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

Integration of a structural features-based preclassifier and a man-machine interactive classifier for a fast multi-stroke character recognition

2003

A transputer-based parallel machine for handwritten character recognition is proposed. An algorithm based on structural features and on a tree classifier was used to accomplish the pre-classification of the unknown sample in order to speed up the recognition process. The algorithm for the final classification is based on the description of the strokes through Fourier descriptors. The learning phase is accomplished through a man-machine interactive process. The proposed system can expand its knowledge base. A special representation of this knowledge base is proposed in order to record a great amount of data in a suitable way. A fast multistroke handwritten isolated character recognition syst…

Image Segmentation based on Genetic Algorithms Combination

2005

The paper describes a new image segmentation algorithm called Combined Genetic segmentation which is based on a genetic algorithm. Here, the segmentation is considered as a clustering of pixels and a similarity function based on spatial and intensity pixel features is used. The proposed methodology starts from the assumption that an image segmentation problem can be treated as a Global Optimization Problem. The results of the image segmentations algorithm has been compared with recent existing techniques. Several experiments, performed on real images, show good performances of our approach compared to other existing methods.
