The goal of this work is to provide hardware abstraction and intuitive operation modes to decrease the development and implementation time of robotic platforms, thus allowing researchers to focus in their main scientific research motivations, e.g., search and rescue, multi-robot surveillance, swarm robotics, among others. To that end, this work presents the development of a compact mobile low-cost robotic platform, denoted as TraxBot, developed and assembled at the Institute of Systems and Robotics (ISR), which has been fully integrated in the well-known Robot Operating System (ROS) framework. Furthermore, several available mobile robots are compared and discussed in terms of their physical ...
Trata-se de um trabalho que se propõe a fazer uma relação histórica entre a história da cidade do Rio de Janeiro, a história do Brasil e a história mundial. A base da relação é a linha da vida ou linha do tempo, criado pela educadora italiana Maria Montessori. Os fatos históricos levantados neste tipo de trabalho não são aprofundados. O objetivo é somente fazer a relação dos fatos para que se tenha uma noção do acontecimento num momento histórico com relação a outro. Este trabalho pode ser considerado como eternamente inacabado, já que sempre se poderá ser acrescentado um dado ou uma análise nova. Além disso, encontra-se dificuldade em fazer a seleção de fatos. Depois, as datas nas fontes consultadas nem sempre são coincidentes. Quanto à seleção, relevaram-se os fatos que tenham servido como marcos históricos, sem comparar um fato com outro em grau de importância. Em relação às datas, optou-se por considerar as que eram mais citadas pelos autores ou as que pareciam mais lógicas no registro da evolução.
An examination of how American newspaper articles on Muslims are strikingly negative by any measure. For decades, scholars and observers have criticized negative media portrayals of Muslims and Islam. Yet most of these critiques are limited by their focus on one specific location, a limited time period, or a single outlet. In Covering Muslims, Erik Bleich and A. Maurits van der Veen present the first systematic, large-scale analysis of American newspaper coverage of Muslims through comparisons across groups, time, countries, and topics. The authors demonstrate conclusively that coverage of Muslims is remarkably negative by any measure. They show that American newspapers have been consistentl...
Mapping Texts is the first introduction to computational text analysis that simultaneously blends conceptual treatments with practical, hands-on examples that walk the reader through how to conduct text analysis projects with real data. The book shows how to conduct text analysis in the R statistical computing environment--a popular programming language in data science.
This 16th International Conference on Information Technology - New Generations (ITNG), continues an annual event focusing on state of the art technologies pertaining to digital information and communications. The applications of advanced information technology to such domains as astronomy, biology, education, geosciences, security and health care are among topics of relevance to ITNG. Visionary ideas, theoretical and experimental results, as well as prototypes, designs, and tools that help the information readily flow to the user are of special interest. Machine Learning, Robotics, High Performance Computing, and Innovative Methods of Computing are examples of related topics. The conference features keynote speakers, the best student award, poster award, service award, a technical open panel, and workshops/exhibits from industry, government and academia.
Cerca de 200 (duzentas) personalidades do Direito do Trabalho e de reconhecida competência que aceitaram a missão de elaborar uma pergunta e uma resposta de algum dos temas atingidos pela reforma e minirreforma trabalhistas. A divisão da obra se deu, aliás, de acordo com o tipo de questionamento enfrentado, ou seja, se referente ao direito individual, coletivo ou processual do trabalho.A novidades trazidas pela Lei da Reforma, assim como na Minirreforma Trabalhista, não são pacíficas. Ao revés, conforme se poderá notar ao longo desta obra, alguns dos coautores são mais entusiasmados com a nova legislação, ao passo que outros, nem tanto. E, assim, longe de tentar elogiar ou critic...
In recent years, with global economic development and population growth, environmental issues have become increasingly prominent. Climate change and energy crisis have become global problems that restrict human development, and so need to be solved urgently. As a comprehensive economic development model, the low-carbon economy can greatly reduce energy and resource consumption, mitigate and adapt to climate change, promote economic development, and thus achieve the goal of sustainable development. Therefore, exploring efficient paths toward sustainable development through carbon reduction is an urgent and challenging research topic currently. This Research Topic aims to conduct scientific re...
