El Cine Independiente Y La Emergente Sociedad Civil Cubana: Un Balance Desde El Grupo De Cineastas Cubanos G20 Hasta El Contexto Actual

Independent cinema in Cuba has historical roots and diverse antecedents, taking into account not only the need for Cuban filmmakers to reclaim their space within Cuban civil society, but also the debate on film production outside the institutional margins of the ICAIC It goes back to the institution’s beginnings, to a decade as confrontational and decisive on the cultural and ideological level as the 1960s. Unquestionably, independent cinema in Cuba has been an area of Cuban culture that historically has aroused the interest of journalists and critics, but the same has not happened in the academic sphere, except for certain foreign and national researchers, including Anne Marie Stock, the Cubans Dean Luis Reyes and Juan Antonio García Borrero and others who have studied the subject from various angles.El cine independiente en Cuba posee múltiples raíces históricas y diversos antecedentes: por una parte, está la necesidad de los cineastas cubanos de reclamar su espacio dentro de la sociedad civil cubana, el debate sobre la producción de filmes fuera de los márgenes institucionales del Instituto cubano del arte e industria cinematográfico ICAIC, que se remonta a los inicios de la institución, a una década tan confrontacional y decisiva en el plano cultural e ideológico como la década de los sesenta. Indiscutiblemente el cine independiente en Cuba ha sido un aspecto de la cultura cubana que históricamente ha despertado el interés de periodistas y críticos, pero no ha sucedido mismo en el ámbito académico, salvo el caso de determinados investigadores extranjeros y nacionales entre los que figuran: Anne Marie Stock, los cubanos Dean Luis Reyes y Juan Antonio García Borrero y otros que han estudiado el tema desde diversas arista

From the Internet of Things to the social innovation and the economy of data

Historically, cities and their citizens have led the largest changes that have been taking place continuously, especially since the transition from an agricultural economy to an industrial one. This phenomenon is especially significant from the mid-eighteenth century and it will become more intense if the predictions that establish that, around the year 2050, approximately 70% of the world population will concentrate in some type of city finally come true. With these boundary conditions, it is evident that the achievement of more efficient and sustainable cities is an unavoidable objective for which politicians, managers and technicians must work in order to guarantee the quality of life of their citizens. Although this paradigm of sustainability and efficiency has always been present in the managers of cities, it has not been until very recently that technology has made available to the responsible parties a plethora of possibilities that, when properly employed, translate into significant savings. At the same time, the day-to-day improvement of the citizens is consolidating a new urban concept in which the different processes and systems that occur in it are continuously monitored in both time and space. This paper reviews the evolution of one of the pioneering examples of such cities, Santander, where an Internet of the Things infrastructure was deployed a decade ago. In this time, multiple technologies and services have been developed and deployed in smart city pilots. The paper discusses the key lessons learnt from the digitalization of the city and the new challenges that have arisen as we were paving the way for a smarter and more liveable city.This work has been funded by the Spanish Government (MINECO) under Grant Agreement No. RTI2018-093475-A-I00 FIERCE (Future Internet Enabled Resilient smart CitiEs) project

3D-LIDAR Based Object Detection and Tracking on the Edge of IoT for Railway Level Crossing

Object detection is an essential technology for surveillance systems, particularly in areas with a high risk of accidents such as railway level crossings. To prevent future collisions, the system must detect and track any object that passes through the monitored area with high accuracy, and this process must be performed fulfilling real-time specifications. In this work, an edge IoT HW platform implementation capable of detecting and tracking objects in a railway level crossing scenario is proposed. The response of the system has to be calculated and sent from the proposed IoT platform to the train, so as to trigger a warning action to avoid a possible collision. The system uses a low-resolution 3D 16-channel LIDAR as a sensor that provides an accurate point cloud map with a large amount of data. The element used to process the information is a custom embedded edge platform with low computing resources and low-power consumption. This processing element is located as close as possible to the sensor, where data is generated to improve latency, privacy, and avoid bandwidth limitations, compared to performing processing in the cloud. Additionally, lightweight object detection and tracking algorithm is proposed in this work to process a large amount of information provided by the LIDAR, allowing to reach real-time specifications. The proposed method is validated quantitatively by carrying out implementation on a car road, emulating a railway level crossing

Exploiting sparse coding: A sliding window enhancement of a random linear network coding scheme

Random Linear Network Coding (RLNC) is a technique that provides several benefits. For instance, when applied over wireless mesh networks, it can be exploited to ease routing solutions as well as to increase the robustness against packet losses. Nevertheless, the complexity of the decoding process and the required overhead might jeopardize its performance. There is a trade-off when deciding the field and block sizes; larger values decrease the probability of transmitting linearly dependent packets, but they also increase both the required overhead and the decoding complexity. In order to overcome these limitations, we propose a sliding window enhancement; a fixed number of packets (fewer than the block size) is combined within every transmission, and the decoding process can therefore take advantage of the algebra with sparse matrices. The paper presents an analytical model, which is first validated and later broaden by means of an extensive simulation campaign carried out over the ns-3 simulator.This work has been supported by the Spanish Government by its funding through the project COSAIF, “Connectivity as a Service: Access for the Internet of the Future” (TEC2012-38754-C02-01)

Integrating a smart city testbed into a large-scale heterogeneous federation of future internet experimentation facilities: the SmartSantander approach

For some years already, there has been a plethora of research initiatives throughout the world that have deployed diverse experimentation facilities for Future Internet technologies research and development. While access to these testbeds has been sometimes restricted to the specific research community supporting them, opening them to different communities can not only help those infrastructures to achieve a wider impact, but also to better identify new possibilities based on novel considerations brought by those external users. On top of the individual testbeds, supporting experiments that employs several of them in a combined and seamless fashion has been one of the main objectives of different transcontinental research initiatives, such as FIRE in Europe or GENI in United States. In particular, Fed4FIRE project and its continuation, Fed4FIRE+, have emerged as "best-in-town" projects to federate heterogeneous experimentation platforms. This paper presents the most relevant aspects of the integration of a large scale testbed on the IoT domain within the Fed4FIRE+ federation. It revolves around the adaptation carried out on the SmartSantander smart city testbed. Additionally, the paper offers an overview of the different federation models that Fed4FIRE+ proposes to testbed owners in order to provide a complete view of the involved technologies. The paper is also presenting a survey of how several specific research platforms from different experimentation domains have fulfilled the federation task following Fed4FIRE+ concepts.This work was partially funded by the European project Federation for FIRE Plus (Fed4FIRE+) from the European Union’s Horizon 2020 Programme with the Grant Agreement No. 732638 and by the Spanish Government (MINECO) by means of the projects ADVICE: Dynamic provisioning of connectivity in high density 5G wireless scenarios (TEC2015-71329-C2-1-R) and Future Internet Enabled Resilient Cities (FIERCE)

Acidentes do trabalho no Brasil, 2004: um estudo ecológico utilizando componentes principais

The present study characterized the States of Brazil in relation to factors related to work injuries. Data came from the Anuário Estatístico de Acidentes do Trabalho (AEAT), 2004. A description of the data was made and the multivariate method Principal Components Analysis was used. Three components were found. The first one contrasted incidence rate and consequence of the accident. States of Santa Catarina, Rio Grande do Sul and Espírito Santo showed high incidence rates and accidents with less grave consequences. The second component revealed an association beteween the consequence of the accident and the risk group. In Roraima, Santa Catarina and Amazonas the grave risk group was associated to the simple medical assistance. The third component contrasted age and incidence. For Rio Grande do Sul, Roraima and Rio de Janeiro, the incidence rate was high, with high levels of temporary disability, for all risk groups and took place among workers above age 40. Finally, it was possible to notice that the Southern States showed a lower risk profile of work injuries, as compared to the Northern States.Brazil, Work Injuries, principal components analysis, ecological study

Integration of utilities infrastructures in a future internet enabled smart city framework

Improving efficiency of city services and facilitating a more sustainable development of cities are the main drivers of the smart city concept. Information and Communication Technologies (ICT) play a crucial role in making cities smarter, more accessible and more open. In this paper we present a novel architecture exploiting major concepts from the Future Internet (FI) paradigm addressing the challenges that need to be overcome when creating smarter cities. This architecture takes advantage of both the critical communications infrastructures already in place and owned by the utilities as well as of the infrastructure belonging to the city municipalities to accelerate efficient provision of existing and new city services. The paper highlights how FI technologies create the necessary glue and logic that allows the integration of current vertical and isolated city services into a holistic solution, which enables a huge forward leap for the efficiency and sustainability of our cities. Moreover, the paper describes a real-world prototype, that instantiates the aforementioned architecture, deployed in one of the parks of the city of Santander providing an autonomous public street lighting adaptation service. This prototype is a showcase on how added-value services can be seamlessly created on top of the proposed architecture.The work described in this paper has been carried out under the framework of the OUTSMART project which has been partially funded by the European Commission under the contract number FP7-ICT-28503
