Soluntina forma urbis. Analisi grafiche e schemi
2015
L’autrice propone un’interpretazione grafica del sito archeologico di Solunto attraverso una lettura digitale per layer concettuali, con l’obiettivo di individuare gli elementi urbani caratterizzanti il sito e definire un ulteriore disegno della città storica. Identificare gli elementi morfologici e tipologici che definiscono la struttura urbana del sito permette di riconoscere una sovrapposizione di sistemi grafici: quello della città sedimentata, costituito dai resti archeologici, quindi dalla materia della città ancora visibile e quello della città virtuale, all’interno del quale percorsi, punti di sosta e di aggregazione diventano elementi nodali per definire la configurazione digitale …
Study on New Product Development, by Networking
2015
The paper presents a situation of working in network in order to design or improve a new product. To implement theoretical models and to validate a working algorithm into a virtual research, there was proposed a specific theme from drilling and chamfering tool. The facilities offered by the research centers – database, software - led to rapid selection and configuration solutions, demonstrating achieving research productivity growth and a substantial reduction of times redesign.
Can planning be a research paradigm in architectural design?
1991
Abstract In the present paper we discuss the possible use of ‘planning’ ° to support architectural design. Architectural design is conceived as a process incorporating non-trivial subprocesses consisting of evolutionary sequences of drawings. The ‘planner’ can be viewed as a tool capable of managing the automatic development of formal descriptions of architectural objects, according to goals and constraints which are interactively assigned or removed by the designer. The main features of a ‘planner’ dedicated to architectural design are then put forward. The system has been implemented at the University of Ancona, Italy.
A new design approach for customised medical devices realized by additive manufacturing
2020
AbstractThe aim of this work is the design of a new customised elbow orthosis completely realized by Additive Manufacturing and the development of generative algorithms for parametric modelling and creation of 3D patterns to be adapted to the CAD model. This work describes a method to perfect the design of a custom elbow orthosis. A reverse engineering approach has been used to digitalize the patient’s arm and the subsequent CAD modelling of the structure of the custom elbow orthosis has been performed. In particular, two algorithms have been implemented for the creation of 3D patterns and Voronoi tessellations. Subsequently, FEM analyses have been carried out to validate the design. Finall…
I disegni di Rosario Gagliardi conservati presso il Dipartimento di Architettura di Palermo
2020
The Department of Architecture of Palermo keeps some drawings related to the activity of one of the greatest architects to have worked in Sicily in the eighteenth century: Rosario Gagliardi (Syracuse, ca. 1690-Noto, 1762). The importance of the small corpus - coming from a collection already constituted in the 18th century (the Mazza Collection) - is also linked to the fact that the drawings include famous edifices of Sicilian Baroque architecture: from the cathedral of San Giorgio in Ragusa to the churches of Santa Chiara and San Domenico in Noto. The thorough examination of the drawings offers the opportunity for a more general reflection on the characteristics of architectural design in …
The diagnostic role of saliva - A Review
2011
As a diagnostic fluid, saliva offers distinctive advantages over serum because it can be collected non-invasively by individuals, even by patient. Does not require special equipment for collection and storage as unlike blood saliva does not clot. Advantageous for person in whom blood drawing is difficult as in obese and haemophilic patient. Whole saliva used for diagnosis of systemic diseases, because it contains serum constituents. These constituents are derived from the local vasculature of the salivary glands and gingival cervicular fluid.This review examines the diagnostic application of saliva for hereditary disorders, autoimmune diseases, malignant and infectious diseases, and endocri…
Numerical study of the components positioning influence on the stability of a reverse shoulder prosthesis
2014
Aim of this paper is to setup a novel procedure able to analyze performances of a reverse shoulder prosthesis when different geometrical configurations are assumed. Nowadays, such a prosthesis is widely used but, because of its novelty, data in literature give poor information about performances and limits to its applicability. The activity has been divided into the following steps. At the beginning the shape of the prosthesis has been digitally acquired via a 3D scanner. Then, CAD models of all prosthetic components have been geometrically optimized in a way to obtain final entities suitable for numerical simulations. After that, CAD assemblies have been created between prosthetic componen…
Sharing Drawings with Smartphones in the Classroom – Art-Based Education in Social Sciences
2020
This article identifies the factors that indicate the opportunity of reviewing the methods in teaching economics in order to overcome the traditional teaching-learning scheme that overvalues rote learning and find formulas that facilitate the development of analytical skills. On the other hand, this work points out the importance of developing creative competences. One way to do this is to introduce artistic practices in the classroom, even in non-artistic subjects. In this work an experience of education based on the arts is presented. Thanks to smartphone cameras, students can share and project drawings in the classroom immediately to facilitate group learning. The proposal is to represen…
Design of the Tube Roll Forming Process Through an Heuristic Algorithm
2002
In the paper the design of an industrial tube roll forming process is developed utilizing an heuristic algorithm, namely the simulated annealing (SA). In particular both the number and the shape of the deforming rolls are determined in order to define the forming sequence. The effectiveness of the results supplied by the SA algorithm is verified both by means of some experiments tests carried out on an industrial tube roll forming equipment and through a set of numerical simulations of the process.
Rubber Forming Processes of Thin Sheets
1999
In the last decade flexible media have been increasingly utilized in sheet metal drawing processes in order to reduce the tooling cost and to improve the product quality. In the present paper an axisymmetric deep drawing process of thin steel sheets is taken into account: in particular a flexible pad is utilized in order to simplify the tooling set. The process mechanics is investigated through numerical simulations and experimental tests with the aim to find out a proper set of operative parameters allowing the stamping of sound components and to highlight the particular deformation path of the drawing cup. The comparison between the numerical predictions and the experimental verification …
