Car style-holon recognition in computer-aided design

2019

Abstract Multi-scale design can presumably stimulate greater intelligence in computer-aided design (CAD). Using the style-holon concept, this paper proposes a computational approach to address multi-scale style recognition for automobiles. A style-holon is both a whole—it contains sub-styles of which it is composed—as well as a part of a broader style. In this paper, we first apply a variable precision rough set-based approach to car evaluation and ranking. Secondly, we extracted and subsequently computed the each car's characteristic lines from the CAD models. Finally, we identified style-holons using the property of a double-headed style-holon. A style-holon is necessarily included in a t…

Visual knowledge processing in computer-assisted radiology: A consultation system

1992

This paper presents Visual Heuristics, a consultation system for diagnosis based on thorax radiograph recording. Visual Heuristics uses both prototypical representations of physiological and pathological states and reasoning aimed to infer conclusions from pathological or physiological conditions, establishing correspondences between pathological or physiological states and semantic descriptions of images. Images are assembled with groups of descriptors that guide the recognition process, achieving the possibility of comparisons with real images on the basis of 'expected' images. The system may be employed to generate a dynamic atlas that does not contain proper images, but generates them.

CAD Software and Interoperability

2009

Decisions taken during the conception phases in huge architectural projects influence a lot the cost and the schedule of the building construction. To ease this decision-making, many mock-ups have been used as a project prototype. This prototyping is useful to test and to improve the conception of projects. Nowadays, collaborative sites that appear on the Web greatly improve the flexibility of the framework’s actors of a distant project [Aliakseyeu, Martens, Subramanian, Vrouble, & Wesselink, 2001; Balaguer & DeGennaro, 1996; Klinker, Dutoit, Bauer, Bayes, Novak, & Matzke, 2002). Digital mock-ups are used to represent future 3D elements of the final product. Digital mock-ups are…

Mixed-aspect fractal surfaces

2013

In order to provide accurate tools to model original surfaces in a Computer Aided Geometric Design context, we develop a formalism based on iterated function systems. This model enables us to represent both smooth and fractal free-form curves and surfaces. But, because of the self-similarity property underlying the iterated function systems, curves and surfaces can only have homogeneous roughness. The aim of our work was to elaborate a method to build parametric shapes (curves, surfaces, ...) with a non-uniform local aspect: every point is assigned a ''geometric texture'' that evolves continuously from a smooth to a rough aspect. The principle is to blend shapes with uniform aspects to defi…

Detection and classification of microcalcifications clusters in digitized mammograms

2005

In the present paper we discuss a new approach for the detection of microcalcification clusters, based on neural networks and developed as part of the MAGIC-5 project, an INFN-funded program which aims at the development and implementation of CAD algorithms in a GRID-based distributed environment. The proposed approach has as its roots the desire to maximize the rejection of background during the analytical pre-processing stage, in order to train and test the neural network with as clean as possible a sample and therefore maximize its performance. The algorithm is composed of three modules: the image pre-processing, the feature extraction component and the Backpropagation Neural Network mod…

Chloroquine for COVID-19: rationale, facts, hopes

2020

The tragedy of the pandemic coronavirus disease 2019 (COVID-19) led to a desperate search for effective treatments. Chloroquine (CQ), an aminoquinoline used for many years for the prophylaxis and therapy of malaria and autoimmune diseases, has been put forward as a treatment option. The fact that CQ is not patented and has been in clinical use for years is a major advantage. CQ has been shown to have antiviral effects in SARS, MERS, Ebola, and HIV infections, but without data showing clinical effectiveness [1, 2]. Does the current level of evidence suffice for prescribing CQ for COVID-19?

Essays on Corruption

2021

Paper III and Paper IV is not published yet. Corruption is blamed for reductions in operational efficiency, information asymmetry, limited income distribution, policy failure, and weak economic growth and development. Corruption can originate from either the “demand-side” (the recipients of the bribe) or the “supply-side” (the givers of the bribe). This double edge effect of corruption on the economy and society makes it a multidisciplinary subject and phenomenon. Thus, scholars from different fields and disciplines, such as finance, banking, economics, accounting, law, foreign aid, and international business, examined and analyzed corruption as a multidisciplinary subject. In this disserta…
