Currently the use of Unmanned Aerial Vehicles (UAVs) for civilian purposes is growing exponentially, whereas in the past it was a technology used only for military objectives. There is an array of applications that can be accomplished with the use of this technology, such as making aerial films on a low budget, coast surveillance, parcel deliverance, and many other applications. However, in a civilian environment, these UAVs systems are typically controlled with a line-of-sight (LOS) technology such as Radio Control (RC), which limits the range that the system can be operated. Therefore, the main objective of this thesis is to study the use of mobile wireless networks as a viable replacement of RC control, to have a full control of the vehicle, providing then an extended mobility to the operator and vehicle. To accomplish this an Unmanned Vehicle System (UVS) was developed in order to monitor and provide the user with the ability to control several drones, such as UAVs and Unmanned Ground Vehicles (UGVs), using mobile networks. The user can operate the vehicle using a Remote Ground Station (RGS) that provides full control of the vehicle, with an android mobile application making it accessible, with no associable costs. On the vehicle a Raspberry PI (RPI) is attached, that receives and handles the information to control the drone and provides the user with a live stream that allowing sight from the Point of View (POV) of the drone, enabling responsibility to the RPI to communicate between the drone and the user. With this approach the system is completely independent from the RC technology, allowing the user to control the vehicle without the need of physical presence on the side, creating a vast new array of uses for this kind of technology. ; Hoje em dia o uso de Unmanned Aerial Vehicles (UAVs) para fins civis esta em crescimento exponencial, no passado era uma tecnologia exclusiva para fins militares. Existe uma variedade de aplicações que podem ser realizadas com o uso dessa tecnologia, tais como: fazer filmagens aéreas, com um orçamento baixo, vigilância de costa, entregar encomendas, e muitas outras aplicações. No entanto, estes sistemas UAVs são geralmente controladas com uma tecnologia line-of-sight (LOS), como controlo de rádio (RC), que limita o intervalo que o sistema pode ser operado. Portanto, o objetivo principal desta tese é estudar o uso de redes móveis para substituição do radio controlo para o controlo total do veiculo, proporcionando mobilidade extra para o operador e veículo. Para realizá-lo foi desenvolvido uma Unnamed Vehicle System (UVS) que monitoraria e fornece ao utilizador a capacidade de controlar vários drones, tais como: UAVs e Unmanned Ground Vehicles (UGVs), utilizando redes móveis. O utilizador pode operar o veículo da Remote Ground Station (RGS), que fornece o controlo total do veículo, é uma aplicação Android tornando assim acessível sem qualquer outro custo. No veículo está presente um Raspberry PI (RPI) que recebe e trata a informação para controlar o avião e fornece ao utilizador uma transmissão de vídeo ao vivo que permite ver a partir do ponto de vista do Drone (POV), tornando o RPI o responsável por fazer a comunicação entre o veículo e o utilizador. Com esta abordagem, o sistema é completamente independente da tecnologia de RC, que permite ao utilizador controlar o veículo sem a necessidade da presença física no local, o que cria de novas aplicações para esta tecnologia.

On 8 May 1794, three months before the fall of Robespierre, Lavoisier was decapitated. The judgment was enforced after the requested postponement was refused in order to complete experiments that would otherwise remain unfinished. The reply it received from the appellate court was brief: "République n'a pas besoin de savants". It's a big estuary! Since then, we have had a beautiful symbol to reflect on the difficult historical relations between the two republics, that of wise people and politicians. Based on this experience, other old and modern cases are identified that allow reflection on the myth of the two cultures. ; Peer reviewed ; On 8 May 1794, three months before the fall of Robespierre, Lavoisier was decapitated.

A patir de esta experiencia, se identifican otros casos, antiguos y modernos, que permiten una reflexión sobre el mito de las dos culturas.

This paper takes the case of Lisbon to explore four different water management regimes – liberal, republican, fascist, and democratic – defined by distinctive historical combinations of politics, environment, technology, and capital. Building on proposals from urban political ecology, it argues that water should be seen as constitutive of the political realm, instead of just considering its management and infrastructure as a reflection of the general political context. The water sector defined in important ways what those political regimes were about: liberalism and private companies with close relations to the state, pushing to convert Lisbon residents into consumers; republicanism and the emergence in the public space of mass protest and biomedical power; fascism and the juxtaposition of private capital and state authoritarianism; democracy and universal access to infrastructure entangled with European Union bureaucracy. We suggest that each water regime corresponds to a nonpredetermined arrangement that escapes traditional deterministic accounts of urban water supply such as the linear sequence of pre-modern systems, the networked modern city, and post material values. The cityscape is understood as a palimpsest in which new layers of historical complexity are added to previous historical dynamics without total erasing of the latter. ; Prenant le cas de Lisbonne, cet article présente quatre régimes de gestion de l'eau – libéral, républicain, fasciste et démocratique – définis par des combinaisons historiquement différenciées de la politique, de l'environnement, de la technologie, et des capitaux. Partant des propositions de l'écologie politique urbaine, nous soutenons que l'eau doit être considérée comme constitutive de la sphère politique, au lieu de ne voir sa gestion et son infrastructure que comme un reflet du contexte politique général. Le secteur de l'eau a largement contribué à donner le sens de ces régimes politiques: le libéralisme et les entreprises privées, en étroite relation avec l'État, poussant ...

A bold redefinition of historical inquiry based on the "cropscape"—the people, creatures, technologies, ideas, and places that surround a crop Human efforts to move crops from one place to another have been a key driving force in history. Crops have been on the move for millennia, from wildlands into fields, from wetlands to dry zones, from one imperial colony to another. This book is a bold but approachable attempt to redefine historical inquiry based on the "cropscape": the assemblage of people, places, creatures, technologies, and other elements that form around a crop. The cropscape is a method of reconnecting the global with the local, the longue durée with microhistory, and people, plants, and places with abstract concepts such as tastes, ideas, skills, politics, and economic forces. Through investigating a range of contrasting cropscapes spanning millennia and the globe, the authors break open traditional historical structures of period, geography, and direction to glean insight into previously invisible actors and forces

O litoral português é um dos mais ameaçados pela erosão costeira na Europa, um fenômeno que deverá ser agravado pelas alterações climáticas, devido à subida do nível médio do mar e à alteração do regime das ondas na costa atlântica. A par desta fragilidade física, a zona costeira tem sido palco de uma acelerada pressão urbana e turística, que em Portugal se acentuou a partir dos anos 60. Este fenômeno gera uma condição de fragilidade social, que se vem associar a uma fragilidade política resultante da incapacidade do Estado para enfrentar com consistência a gestão do litoral. A principal resposta aos problemas do litoral tem sido o investimento em estruturas pesadas fortemente apoiado por fundos comunitários. Apesar deste tipo de investimento estar cada vez mais comprometido, devido à recessão económica e à perspetiva de redução dos fundos europeus. Partindo de três estudos de caso, a Norte, Centro e Sul, neste artigo abordamos a atual condição social da perceção do risco em três zonas instáveis do litoral português, nas quais foram instalados núcleos urbanos com forte motivação turística: Vagueira, Costa da Caparica e Quarteira. Apesar de terem em comum dinâmicas de crescimento recentes, estas zonas apresentam processos diferenciados de ocupação e erosão. O artigo aborda os três locais a partir da sua condição administrativa e dos efeitos das políticas públicas de ordenamento do litoral. E propõe uma reflexão sobre a necessidade de novos modelos institucionais de governança e de gestão costeira sustentáveis.

Late Western colonialism often relied on the practice of imitating indigenous forms of rule in order to maintain power; conversely, indigenous polities could imitate Western sociopolitical forms to their own benefit. Drawing on historical ethnographic studies of colonialism in Asia and Africa, States of Imitation examines how the colonial state attempted to administer, control, and integrate its indigenous subjects through mimetic governmentality, as well the ways indigenous states adopted these imitative practices to establish reciprocal ties with, or to resist the presence of, the colonial state

A transnational approach to understanding and analyzing knowledge circulation. Focusing on what happens to knowledge at national borders, rather than treating it as flowing like currents across them, or diffusing out from center to periphery, the contributors to this collection stress the human intervention that shapes and drives how knowledge is processed, mobilized, and repurposed in transnational transactions to serve differing and uneven interests, constraints, and environments. The chapters consider both what knowledge travels and how it travels across borders of varying permeability that impede or facilitate its movement. They look closely at a vast range of platforms and objects of knowledge, from tangible commodities—like hybrid wheat seeds, penicillin, Robusta coffee, naval weaponry, and high-performance computers—to the more conceptual apparatuses of telecommunications, statistics, and food sovereignty. Moreover, this volume decenters the Global North, tracking how knowledge moves along multiple paths across the borders of Mexico, India, Portugal, Guinea-Bissau, the Soviet Union, China, Angola, and Palestine and the West Bank, as well as the United States and United Kingdom. The variety of the kinds of knowledge addressed in the chapters brings forth an extraordinary array of state and non-state actors and institutions committed to performing the work needed to move knowledge across national borders
