Creative interpretation in web design experience

2017

Insight into how people mentally represent, and thus, make sense of visual designs is the key to understanding how people interact with technological devices. This paper presents a study in which participants were asked to write their interpretations of two webpage design examples, based on what they thought they would say and what would remain as a thought. The data comprised 80 3E templates (N = 40), a template allowing participants to express experiences through writing and drawing. Inductive data analysis through a phenomenological lens revealed that supposed mental and verbal representations concentrated on the following design properties: colors, themes, interface layout and quality, …

OntoSTEP: Enriching product model data using ontologies

2012

The representation and management of product lifecycle information is critical to any manufacturing organization. Different modeling languages are used at different lifecycle stages, for example STEP's EXPRESS may be used at a detailed design stage, while UML may be used for initial design stages. It is necessary to consolidate product information created using these different languages to build a coherent knowledge base. In this paper, we present an approach to enable the translation of STEP schema and its instances to Ontology Web Language (OWL). This gives a model-which we call OntoSTEP-that can easily be integrated with any OWL ontologies to create a semantically rich model. As an examp…

Identity | The colors of project

2017

“Identity | The Colors of Project” è il primo Convegno Internazionale organizzato da 110eLab, Associazione Culturale per la promozione del design siciliano, con la collaborazione dell’INBAR | Sezione Trapani. L’obiettivo, nel quadro del Piano Colore Isole Egadi, è di analizzare la costruzione dell’identità attraverso una strategia sapientemente progettata. Ciò può essere brand, di aziende come di enti, dunque immagine coordinata (marchio, carattere tipografico, gamma cromatica...), oppure una campagna fotografica o ancora una qualità visiva che emerge grazie all’impiego di segni distintivi che fanno sistema. L’attenzione soprattutto è rivolta alla qualità, non soltanto visiva, che definisce…

A Dataset of Annotated Omnidirectional Videos for Distancing Applications

2021

Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…

Economic specialization and diversification at the country and regional level: introducing a conceptual framework to study innovation policy logics

2018

While there has been a shared understanding that innovation policy is about rendering institutional change, there has been an emerging interest in identifying the institutional logics underlying in...

A scalable multiagent system architecture for interactive applications

2013

Interactive applications like crowd simulations need to properly render the virtual world while simulating the interaction of thousands of agents at the same time. The computational workload generated by these two tasks highly increases with the number of the simulated agents, requiring a scalable design of the multiagent system. In this paper, we present, in an unified manner, a distributed multiagent system architecture that can manage large crowds of autonomous agents at interactive rates while rendering multiple views of the virtual world being simulated. This architecture consists of a distributed multiagent system and a complementary distributed visualization subsystem. We also presen…

A distributed visualization system for crowd simulations1

2011

The visualization system of large-scale crowd simulations should scale up with both the number of visuals views of the virtual world and the number of agents displayed in each visual. Otherwise, we could have large scale crowd simulations where only a small percentage of the population is displayed. Several approaches have been proposed in order to efficiently render crowds of animated characters. However, these approaches either render crowds animated with simple behaviors or they can only support a few hundreds of user-driven entities. In this paper, we propose a distributed visualization system for large crowds of autonomous agents that allows the visualization of crowds animated with co…

Computational procedures for plastic shakedown design of structures

2004

The minimum volume design problem of elastic perfectly plastic finite element structures subjected to a combination of fixed and perfect cyclic loads is studied. The design problem is formulated in such a way that incremental collapse is certainly prevented. The search for the structural design with the required limit behaviour is effected following two different formulations, both developed on the grounds of a statical approach: the first one operates below the elastic shakedown limit and is able to provide a suboptimal design; the second one operates above the elastic shakedown limit and is able to provide the/an optimal design. The Kuhn–Tucker conditions of the two problems provide usefu…

A CUDA-based implementation of an improved SPH method on GPU

2021

We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…
