Os três textos que aqui se reúnem — «O conceito de intermedialidade», «Generalidades sobre palcos transitários, elogio do novo ludus mundus» e «Cinema e intermedialidade» — foram escritos visando contribuir para o enquadramento teórico-prático da reflexão no âmbito do projecto de investigação «Intermedialities in Contemporary Theater, Performance and Film — Portuguese Practices and International Context» (Intermedialidades no Teatro, Performance e Cinema Contemporâneos — Práticas Portuguesas e Contexto Internacional), apresentado à Fundação para a Ciência e a Tecnologia em Fevereiro de 2011 e tendo o autor como investigador responsável. E acompanham, igualmente, a preparação do pedido de acreditação prévia da licenciatura em Artes Intermediais, que a Escola Superior de Teatro e Cinema preparou para submeter à Agência de Avaliação e Acreditação do Ensino Superior em Outubro do mesmo ano. O projecto de investigação (código FCT: PTDC/EAT-AVP/119775/2010) visa produzir um retrato da diversidade das práticas intermediais contemporâneas (no domínio das artes), retrato esse que induza efeitos nas literacias e pedagogias das suas áreas científicas — Estudos Artísticos, Artes visuais e performativas — e que estimule a investigação-baseada-na-prática em instituições de ensino superior artístico em Portugal. A instituição residente do projecto é a ESTC, no âmbito do Centro de Investigação em Artes e Comunicação (CIAC), criado pela UALG e ESTC/IPL.

Neste artigo, pretende-se analisar a performance como um gênero artístico que exige uma reflexão em torno do ritual e das transposições dos atos cotidianos para o campo da arte, mas principalmente como uma manifestação que implica a inevitável consideração de que é um recurso cênico não mais calcado na palavra, funcionando como fator determinante para o teatro pós-modernista, que faz constante recusa ao texto em prol do chamado teatro pós-dramático.

: In this work we derive an analytical solution given by Bessel series to the transient and one-dimensional (1D) bioheat transfer equation in a multi-layer region with spatially dependent heat sources. Each region represents an independent biological tissue characterized by temperature-invariant physiological parameters and a linearly temperature dependent metabolic heat generation. Moreover, 1D Cartesian, cylindrical or spherical coordinates are used to define the geometry and temperature boundary conditions of first, second and third kinds are assumed at the inner and outer surfaces. We present two examples of clinical applications for the developed solution. In the first one, we investigate two different heat source terms to simulate the heating in a tumor and its surrounding tissue, induced during a magnetic fluid hyperthermia technique used for cancer treatment. To obtain an accurate analytical solution, we determine the error associated with the truncated Bessel series that defines the transient solution. In the second application, we explore the potential of this model to study the effect of different environmental conditions in a multi-layered human head model (brain, bone and scalp). The convective heat transfer effect of a large blood vessel located inside the brain is also investigated. The results are further compared with a numerical solution obtained by the Finite Element Method and computed with COMSOL Multi-physics v4.1 (c). (c) 2013 Elsevier Ltd. All rights reserved.

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.

O presente Relatório de Estágio tem como objecto de pesquisa a concepção e monitorização de duas Oficinas de Teatro dirigidas a dois grupos de mulheres constituídos, respectivamente, por estudantes universitárias e desempregadas. O estágio realizou-se entre Novembro/2013 e Junho/2014 na Quarta Parede - Associação de Artes Performativas da Covilhã e inseriu-se nos Empowerment Labs, laboratórios formativos que cruzam artes performativas e ciências sociais na reflexão e intervenção sobre a igualdade de género com foco no desemprego feminino. Este relatório expõe os três momentos do processo do estágio: pesquisa de referenciais teórico-práticos, concepção e monitorização das Oficinas de Teatro e reflexão a partir da prática laboratorial. Na pesquisa de referenciais, essencial para delinear a metodologia operacional e o programa de conteúdos, explorei dimensões como o feminismo e a igualdade de género, e procurei compreender de que forma o empowerment, a pedagogia de Paulo Freire e as metodologias do teatro aplicado serviam os objectivos do meu trabalho. A realização das oficinas foi o momento de experimentar as metodologias e o programa delineado. Tendo a igualdade de género como temática unificadora, o empowerment através da arte como objectivo maior e o teatro aplicado como base metodológica, as oficinas inserem-se nos processos de educação não-formal aplicados ao incremento de recursos intelectuais, emocionais, sociais, expressivos e criativos e, neste caso específico, à ampliação da consciência de género. Neste sentido, as oficinas desenvolveram uma abordagem metodológica processual, participativa e multidisciplinar, orientada para a pesquisa performativa, primeiro de uma dramaturgia individual, depois de uma dramaturgia do colectivo e, por fim, de uma dramaturgia orientada para a igualdade de género. O conceito de “dramaturgia” surge aqui no sentido metodológico do pachwork (trabalho com retalhos) e do sampling (recolha e transformação de materiais), relevante sobretudo na última fase, dedicada à construção colectiva de um exercício performativo apresentado publicamente.

This thesis aims at addressing the development of autonomous behaviors, for search and exploration with a mini-UAV (Unmanned Aerial Vehicle), or also called MAV (Mini Aerial Vehicle) prototype, in order to gather information in rescue scenarios. The platform used in this work is a four rotor helicopter, known as quad-rotor from the German company Ascending Technologies GmbH, which is later assembled with a on-board processing unit (i.e. a tiny light weight computer) and a on-board sensor suite (i.e. 2D-LIDAR and Ultrasonic Sonar). This work can be divided into two phases. In the first phase an Indoor Position Tracking system was settled in order to obtain the Cartesian coordinates (i.e. X, Y, Z) and orientation (i.e.heading) which provides the relative position and orientation of the platform. The second phase was the design and implementation of medium/high level controllers on each command input in order to autonomously control the aircraft position, which is the first step towards an autonomous hovering flight, and any autonomous behavior (e.g. Landing, Object avoidance, Follow the wall). The main work is carried out in the Laboratory ”Intelligent Systems for Emergencies and Civil Defense”, in collaboration with ”Dipartimento di Informatica e Sistemistica” of Sapienza Univ. of Rome and ”Istituto Superiore Antincendi” of the Italian Firemen Department.

In the last twenty years genetic algorithms (GAs) were applied in a plethora of fields such as: control, system identification, robotics, planning and scheduling, image processing, and pattern and speech recognition (Bäck et al., 1997). In robotics the problems of trajectory planning, collision avoidance and manipulator structure design considering a single criteria has been solved using several techniques (Alander, 2003). Most engineering applications require the optimization of several criteria simultaneously. Often the problems are complex, include discrete and continuous variables and there is no prior knowledge about the search space. These kind of problems are very more complex, since they consider multiple design criteria simultaneously within the optimization procedure. This is known as a multi-criteria (or multiobjective) optimization, that has been addressed successfully through GAs (Deb, 2001). The overall aim of multi-criteria evolutionary algorithms is to achieve a set of non-dominated optimal solutions known as Pareto front. At the end of the optimization procedure, instead of a single optimal (or near optimal) solution, the decision maker can select a solution from the Pareto front. Some of the key issues in multi-criteria GAs are: i) the number of objectives, ii) to obtain a Pareto front as wide as possible and iii) to achieve a Pareto front uniformly spread. Indeed, multi-objective techniques using GAs have been increasing in relevance as a research area. In 1989, Goldberg suggested the use of a GA to solve multi-objective problems and since then other researchers have been developing new methods, such as the multi-objective genetic algorithm (MOGA) (Fonseca & Fleming, 1995), the non-dominated sorted genetic algorithm (NSGA) (Deb, 2001), and the niched Pareto genetic algorithm (NPGA) (Horn et al., 1994), among several other variants (Coello, 1998). In this work the trajectory planning problem considers: i) robots with 2 and 3 degrees of freedom (dof ), ii) the inclusion of obstacles in the workspace and iii) up to five criteria that are used to qualify the evolving trajectory, namely the: joint traveling distance, joint velocity, end effector / Cartesian distance, end effector / Cartesian velocity and energy involved. These criteria are used to minimize the joint and end effector traveled distance, trajectory ripple and energy required by the manipulator to reach at destination point. Bearing this ideas in mind, the paper addresses the planning of robot trajectories, meaning the development of an algorithm to find a continuous motion that takes the manipulator from a given starting configuration up to a desired end position without colliding with any obstacle in the workspace. The chapter is organized as follows. Section 2 describes the trajectory planning and several approaches proposed in the literature. Section 3 formulates the problem, namely the representation adopted to solve the trajectory planning and the objectives considered in the optimization. Section 4 studies the algorithm convergence. Section 5 studies a 2R manipulator (i.e., a robot with two rotational joints/links) when the optimization trajectory considers two and five objectives. Sections 6 and 7 show the results for the 3R redundant manipulator with five goals and for other complementary experiments are described, respectively. Finally, section 8 draws the main conclusions.
