We discuss a conjecture of J. R. Griggs relating the maximum number of leaves in a spanning tree of a simple, connected graph to the order and independence number of the graph. We prove a generalization of this conjecture made by the computer program Graffiti, and discuss other similar conjectures, including several generalizations of the theorem that the independence number of a simple, connec...

We analyze the feedback loop in Tele-Graffiti, a cameraprojector based remote sketching system which we recently developed. We derive the gain through the feedback loop and the final images that will be viewed by the users of the system. We then derive the “optimal gain” as the gain that results in the final viewed images being as close as possible to the sum of the images actually drawn on the...

This paper is an attempt to add knowledge scholarship in a field that has attracted less attention from researchers. It presents study of graffiti found on board located inside gym Madrid was carried out order get grasp the functions and gain insight into discursive practices gyms. Data analysis focused texts while overlooking graffiti’s non-verbal features following Fairclough’s (2004, 2013) a...

Admired and despised, created destroyed, legal illegal: Contemporary graffiti are polarising, not everybody agrees to label them as cultural heritage. However, if one is among the steadily increasing number of heritage professionals academics that value these short-lived creations, their digital documentation can be considered a part our legacy future generations. To document geometric spectral...

O espaço urbano, como campo de significação, comporta um conjunto relações históricas, políticas, econômicas, sociais, estéticas e culturais. Este artigo, abordagem qualitativa, exploratória, descritiva, bibliográfica documental, tem objeto estudo os graffiti produzidos no bairro Campo dos Alemães, região periférica da cidade São José Campos, sede Região Metropolitana do Vale Paraíba Paulista, ...

In this paper, we take a retrospective look at the problem of querying and updating location dependent data in massively distributed mobile environments. Looking forward, we paint our vision of the future dataspace – physical space enhanced with embedded digital information. Finally we describe a few of the applications enabled by dataspace due to the availability of large scale ad-hoc sensor n...

The article touches upon graffiti discourse as a form of rhetorical speech and tries to analyse it according the three strategies persuasion suggested by Aristotle: ethos, pathos logos. reveals how specific is in terms using these latter make more powerful persuasive. Also, an attempt made reveal role metaphor performance strategy discourse.

Graffiti and street art research (GSAR) has become more acknowledged within the academic discourse; however, it much to gain from theorising its methodological aspects. As a multidisciplinary field, GSAR mostly used qualitative methods, exploring urban space through methods that range visual recordings ethnography, emphasising researchers’ reflexivity. This approach has, paid little attention r...
