Integration of technologies for understanding the functional relationship between reef habitat and fish growth and production

Functional linkage between reef habitat quality and fish growth and production has remained elusive. Most current research is focused on correlative relationships between a general habitat type and presence/absence of a species, an index of species abundance, or species diversity. Such descriptive information largely ignores how reef attributes regulate reef fish abundance (density-dependent habitat selection), trophic interactions, and physiological performance (growth and condition). To determine the functional relationship between habitat quality, fish abundance, trophic interactions, and physiological performance, we are using an experimental reef system in the northeastern Gulf of Mexico where we apply advanced sensor and biochemical technologies. Our study site controls for reef attributes (size, cavity space, and reef mosaics) and focuses on the processes that regulate gag grouper (Mycteroperca microlepis) abundance, behavior and performance (growth and condition), and the availability of their pelagic prey. We combine mobile and fixed-active (fisheries) acoustics, passive acoustics, video cameras, and advanced biochemical techniques. Fisheries acoustics quantifies the abundance of pelagic prey fishes associated with the reefs and their behavior. Passive acoustics and video allow direct observation of gag and prey fish behavior and the acoustic environment, and provide a direct visual for the interpretation of fixed fisheries acoustics measurements. New application of biochemical techniques, such as Electron Transport System (ETS) assay, allow the in situ measurement of metabolic expenditure of gag and relates this back to reef attributes, gag behavior, and prey fish availability. Here, we provide an overview of our integrated technological approach for understanding and quantifying the functional relationship between reef habitat quality and one element of production – gag grouper growth on shallow coastal reefs.

Improving Content Delivery Efficiency through Multi-Layer Mobile Edge Adaptation

This paper presents a novel architecture for optimizing the HTTP-based multimedia delivery in multi-user mobile networks. This proposal combines the usual client-driven dynamic adaptation scheme DASH-3GPP with network-assisted adaptation capabilities, in order to maximize the overall Quality of Experience. The foundation of this combined adaptation scheme is based on two state of the art technologies. On one hand, adaptive HTTP streaming with multi-layer encoding allows efficient media delivery and improves the experienced media quality in highly dynamic channels. Additionally, it enables the possibility to implement network-level adaptations for better coping with multi-user scenarios. On the other hand, mobile edge computing facilitates the deployment of mobile services close to the user. This approach brings new possibilities in modern and future mobile networks, such as close to zero delays and awareness of the radio status. The proposal in this paper introduces a novel element, denoted as Mobile Edge-DASH Adaptation Function, which combines all these advantages to support efficient media delivery in mobile multi-user scenarios. Furthermore, we evaluate the performance enhancements of this content- and user context-aware scheme through simulations of a mobile multimedia scenario.

Learning Multirobot Hose Transportation and Deployment by Distributed Round-Robin Q-Learning

Multi-Agent Reinforcement Learning (MARL) algorithms face two main difficulties: the curse of dimensionality, and environment non-stationarity due to the independent learning processes carried out by the agents concurrently. In this paper we formalize and prove the convergence of a Distributed Round Robin Q-learning (D-RR-QL) algorithm for cooperative systems. The computational complexity of this algorithm increases linearly with the number of agents. Moreover, it eliminates environment non sta tionarity by carrying a round-robin scheduling of the action selection and execution. That this learning scheme allows the implementation of Modular State-Action Vetoes (MSAV) in cooperative multi-agent systems, which speeds up learning convergence in over-constrained systems by vetoing state-action pairs which lead to undesired termination states (UTS) in the relevant state-action subspace. Each agent's local state-action value function learning is an independent process, including the MSAV policies. Coordination of locally optimal policies to obtain the global optimal joint policy is achieved by a greedy selection procedure using message passing. We show that D-RR-QL improves over state-of-the-art approaches, such as Distributed Q-Learning, Team Q-Learning and Coordinated Reinforcement Learning in a paradigmatic Linked Multi-Component Robotic System (L-MCRS) control problem: the hose transportation task. L-MCRS are over-constrained systems with many UTS induced by the interaction of the passive linking element and the active mobile robots.

Dinâmicas de uma juventude conectada: a mediação dos dispositivos móveis nos processos de aprender-ensinar

A Tese apresenta os resultados de um estudo que buscou conhecer de que modo os usos dos dispositivos móveis e ubíquos podem mediar a superação do desencontro entre as práticas juvenis e a cultura escolar, entendendo que esse desencontro tem se traduzido por tensões que, se já vinham acontecendo a partir da introdução do computador em todas as áreas da produção humana, ampliam-se ainda mais com o crescente uso de celulares e smartphones por jovens estudantes, dentro e fora das salas de aula. A pesquisa - realizada através de oficinas com alunos do sétimo ao nono ano de uma escola da Rede Municipal do Rio de Janeiro - propôs e criou situações favoráveis à compreensão dos modos pelos quais as tecnologias móveis e ubíquas podem ser apropriadas pelo campo da Educação. Os conceitos bakhtinianos de alteridade, dialogismo e exotopia orientaram o encaminhamento metodológico do estudo. A complexidade das questões relativas à interseção entre educação, comunicação, juventudes, mobilidade, cidade, redes sociais, subjetividades, foi examinada com base nas contribuições teóricas de Lucia Santaella, André Lemos, Pierre Lévy, Bruno Latour, Lucia Rabello de Castro, Paulo Carrano e Julio Dayrell, entre outras. Os resultados apontam para a pertinência de se considerar os usos dos referidos artefatos como mediadores de práticas pedagógicas mais concernentes com as práticas culturais dos sujeitos contemporâneos.

De Mercator ao Googlemaps: Mapas colaborativos digitais no ensino e aprendizagem de geografia

Recentemente as tecnologias digitais de informação e comunicação vêm promovendo alterações na forma como os mapas são produzidos, o que pode ser uma fonte de renovação na educação geográfica em tempos de cibercultura. Nos últimos anos, aplicativos e sites voltados para o mapeamento on-line tornaram-se mais uma forma de expressão da cultura digital. Esta dissertação consiste em uma investigação acerca das possíveis mediações das cartografias multimídias e colaborativas, construídas através de interfaces da internet, em processos de ensino e aprendizagem de geografia. Os mapas colaborativos digitais são representações cartográficas produzidas de forma interativa, descentralizada e em rede. Eles permitem a inserção colaborativa de conteúdos hipermidiáticos (textos, fotos, vídeos) georreferenciados e constituem uma forma alternativa e potencialmente subversiva de produção cartográfica. A pesquisa realizada com alunos do nono ano de uma escola da Rede Municipal de Itaboraí se deu a partir do desenvolvimento de um projeto de mapeamento da região onde os alunos vivem. Os resultados revelaram que estas práticas cartográficas podem contribuir para a superação do atual mal-estar na relação entre jovens e a cultura escolar, bem como favorecer a construção de práticas pedagógicas comprometidas com a formação de cidadãos críticos e engajados.

Mobilized ad-hoc networks: A reinforcement learning approach

Research in mobile ad-hoc networks has focused on situations in which nodes have no control over their movements. We investigate an important but overlooked domain in which nodes do have control over their movements. Reinforcement learning methods can be used to control both packet routing decisions and node mobility, dramatically improving the connectivity of the network. We first motivate the problem by presenting theoretical bounds for the connectivity improvement of partially mobile networks and then present superior empirical results under a variety of different scenarios in which the mobile nodes in our ad-hoc network are embedded with adaptive routing policies and learned movement policies.

Traversing digital learning landscapes: an Institutional and faculty case study.

Within the UK, there is a growing awareness to better understand what online educational technologies can offer in relation to learning and teaching, and how social technologies are changing communication and collaboration out with formal education. The concept of the ‘digital university’ is being widely debated within the UK Higher education sector (McCluskey and Winter, 2012), becoming embedded in educational policy, and beginning to be explored within many institutions. This session will report on one such institutional initiative, undertaken at Edinburgh Napier University in Scotland. A Digital Futures Working Group was established to: benchmark best practice in key areas including digitally enhanced education and digital literacies development; identify areas for short term action; and to produce a robust ‘digital agenda’ to inform the future direction of the university. Pivotal to this was the recognition to evolve staff digital pedagogical practices and to harness emerging digital opportunities, meet learner expectations, and meet wider expectations for contemporary able citizens. This session will be delivered in two parts. Firstly we will provide an insight into the focus of the project and the rich picture methodology used to consult with staff and students. Secondly we will specify the outcomes produced, and provide a case study of how the Faculty of Health, Life and Social Sciences engaged with the process and the progression of their digitally enabled educational practices.

Work on the Move: mobile and nomadic working methodologies.

‘Work on the move’ is a design, process-driven methodology, which uses multiple locations within an outdoors setting and movement between locations, all of which function as learning places, confined to a specified time period. Between 2012 and 2015, a team of international Higher Education product design educators (all members of Carousel, a co-operation of Erasmus members in Zwolle, Edinburgh, Nantes, Rome, Kortrijk and Oslo), industry professionals and product design students developed and tested four case studies. Each case study was conducted in a different international location and was constructed with a different focus, to help define and refine a definitive working methodology. ‘Work on the move’ explores the influence of ‘place’ upon design, in terms of the impact it has on productivity and creative problem-solving, when working away from the traditional studio/office-based environment. It also explores the significance of shared place, when working directly with a client in situ, and experiencing the place-based influences upon their businesses. While identifying location as part of the design process, the study also seeks to understand the effects of time restriction and working in transit upon creativity and productivity, within the context of specific projects.
