Advanced Techniques used in Numerical Simulation for Deep-drawing Process

2019

The present paper analyse the main characteristics of the numerical simulation by finite element method of the deep-drawing processes. Also the authors’ highlights the mathematical apparatus and the calculus method used for numerical simulations of metal forming processes in many of the current simulation software. The authors present the capabilities of the inverse analysis, direct analysis, implicit analysis (for springback simulation) and the optimisation analysis applied to explicit formulations.

Conjectural reconstruction from archive drawings: methodological aspects

2018

The digital reconstruction of architectural projects starting from archive sources is a well established disciplinary application useful for the study and analysis of architecture and its relations with the historical context as well as for the representation of volumes and spaces not visible in the original documents. Given the importance recognized to these operations which inevitably involve processes of hermeneusi we propose methodological guidelines for the drafting a protocol limiting arbitrariness as much as possible. The analysis was carried out on three projects by Giuseppe Damiani Almeyda (Capua 1834 - Palermo 1911), Ernesto Basile (Palermo 1857-1932) and Salvatore Benfratello (Pa…

Using tablets as tools for learner-generated drawings in the context of teaching the kinetic theory of gases

2014

Even though research suggests that the use of drawings could be an important part of learning science, learnergenerated drawings have not received much attention in physics classrooms. This article presents a method for recording students’ drawings and group discussions using tablets. Compared to pen and paper, tablets offer unique benefits, which include the recording of the whole drawing process and of the discussion associated with the drawing. A study, which investigated the use of drawings and the need for guidance among Finnish upper secondary school students, is presented alongside ideas for teachers on how to see drawing in a new light. peerReviewed

Self-Representation of Children Suffering from Congenital Heart Disease and Maternal Competence

2013

Background: Child development may be subject to forms of motor, physical, cognitive and self-representation impairments when complex congenital heart disease (CHD) occurs. In some cases, inadequacy of both self-representation as well as the family system are displayed. It seems to be important to search the likely internal and external resources of the CHD child, and the possible connections among such resources, which may help him/her to manage his/her own risk condition. Design and Methods: The research project inquires the possible resources related to the self-representation and self-esteem levels of the CHD child, and those related to maternal self-perception as competent mothers. A gr…

Dynamic Perception of Plastic Movements: Biomechanics and Digital Artifacts

2017

The article offers some reflections on the body-space relationship through images, graphic translations and visual studies that converge into a contemporary digital illuminated avant-garde of the fourth virtual dimension. Starting from the study of the Soviet coreutics of the 1920s and the biomechanics of multimedia performances, it moves on the cinesthetic suggestions and to the dance theorization integrated with the musical score. Finally, some contemporary forms of digital image production are taken into account by addressing a number of issues regarding the exploration of the object-image and its experiential re-elaboration through the production of new graphic knowledge.

Randazzo nell'opera di Walter Leopold

2022

In 2021 a group of researchers and students on both sides of the Atlantic Ocean toasted ten years of The Medieval Kingdom of Sicily Image Database project (https://kos.aahvs.duke.edu/). This collection of historical images of medieval monuments in Southern Italy was launched in 2011. Its purpose was to document the complex history of this highly diverse patrimony with visual documents that testify to the cultural richness of the Italian South. Online since October 2016, the project was fostered by Caroline Bruzelius at Duke University (NC). It has now become an invaluable research and study tool thanks to her charisma and her indefatigable enthusiasm in the face of ever-new intellectual cha…

Measuring Inaccessible Residual Stresses Using Multiple Methods and Superposition

2010

The traditional contour method maps a single component of residual stress by cutting a body carefully in two and measuring the contour of the cut surface. The cut also exposes previously inaccessible regions of the body to residual stress measurement using a variety of other techniques, but the stresses have been changed by the relaxation after cutting. In this paper, it is shown that superposition of stresses measured post-cutting with results from the contour method analysis can determine the original (pre-cut) residual stresses. The general superposition theory using Bueckner’s principle is developed and limitations are discussed. The procedure is experimentally demonstrated by determini…

Conoscenza, valorizzazione e fruizione degli insediamenti rupestri: le chiese di S. Maria delle Croci (MT) e S. Antonio Abate a Nardò (LE)

The contribution illustrates the study conducted on some rocky churches of the Apulian territory aimed at the knowledge, monitoring and enhancement of the Cave-Heritage through the most modern digital technologies applied to the field of cultural heritage

<strong>Review of the New Caledonian species of the genus <em>Pactola</em> Pascoe, 1876 (Coleoptera: Curculionidae: Eugnomini), wit…

2014

The two species of the genus Pactola Pascoe known from New Caledonia, P. convexa (Montrouzier) and P. setacea (Montrouzier), are redescribed and two new species (P. magna sp. n. and P. proxima sp. n.) are described. Pactola kanalensis (Perroud) is a new junior synonym of P. setacea (Montrouzier). A neotype of Pactola setacea (Montrouzier) and lectotypes of Pactola convexa (Montrouzier) and Pactola kanalensis (Perroud) are designated. Pactola nigra Hudson is considered conspecific with Pactola variabilis Pascoe but formal synonymy requires further study. Colour photographs of the dorsal habitus and line drawings of taxonomically relevant structures of all species are provided, as well as an …
