Embodied Autonomy in Digital Ecosystems: From Bio-Inspired Agents to Cognitive Systems

This paper proposes to promote autonomy in digital ecosystems so that it provides agents with information to improve the behavior of the digital ecosystem in terms of stability. This work proposes that, in digital ecosystems, autonomous agents can provide fundamental services and information. The final goal is to run the ecosystem, generate novel conditions and let agents exploit them. A set of evaluation measures must be defined as well. We want to provide an outline of some global indicators, such as heterogeneity and diversity, and establish relationships between agent behavior and these global indicators to fully understand interactions between agents, and to understand the dependence and autonomy relations that emerge between the interacting agents. Individual variations, interaction dependencies, and environmental factors are determinants of autonomy that would be considered. The paper concludes with a discussion of situations when autonomy is a milestone

Una eina innovadora per a la informació i la divulgació geogràfica: l’Atles comarcal de Catalunya en format digital

Due to the edition of the new Atles comarcal de Catalunya by the Institut Cartogràfic de Catalunya in digital format, we look at the structure of their contents and the dynamics of its use. Likewise, it is detailed which methodology was utilized to perform it. Finally, some reflections on the innovations that this new product entails in textual and cartographic areas are proposed, especially related to the current socioeconomic context and new employed technologies

Predators of Spotted Flycatcher Muscicapa striata nests in southern England as determined by digital nest cameras

Capsule Avian predators are principally responsible. Aims To document the fate of Spotted Flycatcher nests and to identify the species responsible for nest predation. Methods During 2005-06, purpose-built, remote, digital nest-cameras were deployed at 65 out of 141 Spotted Flycatcher nests monitored in two study areas, one in south Devon and the second on the border of Bedfordshire and Cambridgeshire. Results Of the 141 nests monitored, 90 were successful (non-camera nests, 49 out of 76 successful, camera nests, 41 out of 65). Fate was determined for 63 of the 65 nests monitored by camera, with 20 predation events documented, all of which occurred during daylight hours. Avian predators carried out 17 of the 20 predations, with the principal nest predator identified as Eurasian Jay Garrulus glandarius. The only mammal recorded predating nests was the Domestic Cat Felis catus, the study therefore providing no evidence that Grey Squirrels Sciurus carolinensis are an important predator of Spotted Flycatcher nests. There was no evidence of differences in nest survival rates at nests with and without cameras. Nest remains following predation events gave little clue as to the identity of the predator species responsible. Conclusions Nest-cameras can be useful tools in the identification of nest predators, and may be deployed with no subsequent effect on nest survival. The majority of predation of Spotted Flycatcher nests in this study was by avian predators, principally the Jay. There was little evidence of predation by mammalian predators. Identification of specific nest predators enhances studies of breeding productivity and predation risk.

A TV digital brasileira a serviço do processo judicial eletrônico: o ambiente da interatividade da TV digital brasileira como proposta para um modelo na gravação de audiência das varas federais criminais

Este trabalho descreve algumas das soluções atualmente adotadas pelos tribunais federais para a gravação de audiência, bem como indica a oportunidade que o ambiente de interatividade da TV Digital Brasileira oferece para uma proposta de modelo de documento eletrônico de escritório que sirva de suporte para o resultado da gravação de audiência (texto, som e imagem), bem como possa contribuir para a mudança de paradigma dos atuais sistemas processuais (softwares). O objetivo é estabelecer um padrão fundamentado em uma política pública (Governo Eletrônico Brasileiro e Sistema Brasileiro de TV Digital Terrestre), onde não existam restrições comerciais quanto ao uso das novas tecnologias de comunicação e informação no que se refere ao mínimo para se privilegiar a inclusão social sem perda de eficiência. O trabalho é formado por dois tipos de conteúdo: parte textual e parte digital. A parte textual contém o resultado de uma pesquisa realizada junto aos tribunais federais, bem como apresenta os principais pontos do Governo Eletrônico Brasileiro e do Sistema Brasileiro de TV Digital Terrestre. Ainda descreve a estrutura montada na elaboração e realização da parte digital. Por sua vez, a parte digital reúne o material utilizado para a apresentação de protótipos (vídeos e exemplos de aplicações), para demonstrar as possibilidades de interatividade da TV Digital Brasileira e dos benefícios que os jurisdicionados e os operadores do Direito alcançariam com a proposta.

Uma fundamentação matemática para processamento digital de sinais intervalares

This work deals with a mathematical fundament for digital signal processing under point view of interval mathematics. Intend treat the open problem of precision and repesention of data in digital systems, with a intertval version of signals representation. Signals processing is a rich and complex area, therefore, this work makes a cutting with focus in systems linear invariant in the time. A vast literature in the area exists, but, some concepts in interval mathematics need to be redefined or to be elaborated for the construction of a solid theory of interval signal processing. We will construct a basic fundaments for signal processing in the interval version, such as basic properties linearity, stability, causality, a version to intervalar of linear systems e its properties. They will be presented interval versions of the convolution and the Z-transform. Will be made analysis of convergences of systems using interval Z-transform , a essentially interval distance, interval complex numbers , application in a interval filter.

Evaluation of chronic periapical lesions by digital subtraction radiography by using adobe photoshop CS: A technical report

The purpose of this study was to describe a new technique by using Adobe Photoshop CS (San Jose, CA) image-analysis software to evaluate the radiographic changes of chronic periapical lesions after root canal treatment by digital subtraction radiography. Thirteen upper anterior human teeth with pulp necrosis and radiographic image of chronic periapical lesion were endodontically treated and radiographed 0, 2, 4, and 6 months after root canal treatment by using a film holder. The radiographic films were automatically developed and digitized. The radiographic images taken 0, 2, 4, and 6 months after root canal therapy were submitted to digital subtraction in pairs (0 and 2 months, 2 and 4 months, and 4 and 6 months) choosing image, calculation, subtract, and new document tools from Adobe Photoshop CS image-analysis software toolbar. The resulting images showed areas of periapical healing in all cases. According to this methodology, the healing or expansion of periapical lesions can be evaluated by means of digital subtraction radiography by using Adobe Photoshop CS software.
