Experimental Investigations and Numerical Analysis for Improving Knowledge of Incremental Sheet Forming Process for Sheet Metal Parts
2009
The paper is related to the analysis of shape distortions and springback effects arising in Single Point Incremental Forming. An experimental set up has been designed and manufactured to carry single point incremental forming on small size sheet metal parts. The experimental set up is mounted on 3-axes CNC milling machine tool and the forming tool is attached and move with the spindle. Experiments have been carried out on sheet metal parts to obtain tronconical shapes. The forming strategy associated to the movement of the forming tool has been also investigated. The experiments indicate that shape distortions arising in the corners of the tronconical shape are clearly related to forming st…
Investigating the Reliability of Stationary Design Rainfall in a Mediterranean Region under a Changing Climate
2023
Extreme rainfall events have been more frequent in recent decades, potentially as a climate change effect. This has been leading to a higher risk of the failure of existing hydraulic infrastructures, and to a higher awareness regarding the unreliability of design rainfall calculated with reference to historical data recorded in the last century. With this in mind, the present study questions the stationary assumption of the rainfall Depth–Duration–Frequency curves commonly used in Sicily, the biggest island of the Mediterranean Sea. Quantiles derived from the most up-to-date regional method, regarding Sicily, based on observations in the period 1928–2010, have been compared with those extra…

Fashion Technology : What Are the Limits of Emerging Technological Design Thinking?
2021
Designing intelligent technologies is a multidisciplinary process. From this perspective, fashion has continued to be an under explored dimension of technology design. While there persistently are connections between the term fashion and the clothing design industry, an historical and sociological approach to fashion reveals a much deeper and permeating understanding of the notion and its implications across the technological world. During recent popular developments, the interrelationship between fashion as a concept and technology as components and proponents of fashion – technology as fashion promoter (think of Tiktok, Instagram, Facebook and even LinkedIn for example), and technology as…
Diffusion of digital culture: analysis of the Internet forum of a MOOC
2017
When MOOCs are increasing all over the world as a mean for improving the diffusion of culture and science, it is interesting to observe how those MOOCS build communities of knowledge, and which is the impact of those communities on the acquisition of knowledge. In this article, we present the principles of design of the MOOC Digital & Culture Writing that aims to spread digital culture. Then, we analyse the messages posted on forums by the related community, and the cognitive process to which they refer. Posts analysis reveals reflexivity processes when participants are writing on forums. It appears that reflexivity cognitive processes are at the heart of both social interaction and digital…
Designing and investigating pedagogical scripts to facilitate computer-supported collaborative learning
2008
Computer-supported collaborative learning (CSCL) appears to provide a promising social approach to foster learning. On the other hand, recent studies have indicated that when learners are left on their own, it is often difficult for teams to engage in productive interactions. Therefore, the use of collaboration scripts as instructional support has been presented as a possibility to trigger productive collaborative activities. This study provides knowledge of collaboration scripts as a pedagogical method to facilitate group processes in virtual environments in authentic educational contexts. The findings indicate that scripts as external support can help students proceed in solving learning …
Socio-emotional Experience in Human Technology Interaction Design – A Fashion Framework Proposal
2021
Technology designers and developers can be understood as social experience (SE) mediators. In user experience (UX), notions of SE have served to identify and define the factors contributing to human-technology interaction (HTI). Three dominant perspectives have been promoted in UX discourse: 1) SE of brand, brand value and consumer culture; 2) technology design as mediator of human-to-human interactions; and 3) meaning generation through action and interaction between actors. Symbolic interactionalism understands meaning as occurring through dialogue, in the construction of the social self, promoting self-reflection as a social construction. This theorisation of social experience is valuabl…
Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…
The line model of form and emotion : perspectives on western design
2018
This paper introduces a new model of form, emotion, and semantics through a process of form abstraction utilizing lines. Understanding the emotional and semantic value of form is a complex task, and many theories have been developed. Analyzing the visual arts through line relationships and interactions is a conceptually novel approach and offers new avenues for advancing studies in form theory, theories of emotion and perception, and design generally. By examining literature in visual perception, form theory, and emotion, and by historically analyzing changes in form through the aesthetic arts and then reducing these aesthetic elements into basic linear foundations, we developed the line mo…
Aesthetic Appeal and Visual Usability in Four Icon Design Eras
2016
Technological artefacts express time periods in their visual design. Due time, visual culture changes and thus affects the design of pictorial representations in technological products, such as icons in user interfaces. Previous research of temporal aspects in human-computer interaction has been focusing on particular interaction situations, but not on the effects of design eras on user experience. The influence of icon design styles of different eras on aesthetic and usability experiences was studied with the method of primed product comparisons. Affective preferences and their processing times were analysed in order to examine visual usability in terms of semantic distance and aesthetic a…
