Robotics

Robotics is the mix of knowledge of mechanical, computer, electrical and electronics with the purpose to automate processes performed by humans through devices that are known robots.

The word “robot” came from the Czech’s word “robota”, that meaning "forced job".

The pioneer models of robotics applications have been found in an old Greek civilization. Those “robots” were systems that used pneumatic pumps and weights, they looked like humans or animals. The ancient civilizations had no practical or economic necessity and there wasn’t any complex productivity system that would require the existence of such instruments. Arab scientists have added an important new concept to the traditional idea of robotics, concentrating their searches in order to assign tasks to robots according the human needs. The term robotics became known worldwide after a publication of the book "I, Robot" by Isaac Asimov.

Robótica

A robótica é o conjunto de conhecimentos que integram a mecânica, a computação, a elétrica e a eletrônica com o fim de automatizar processos feitos por seres humanos através de dispositivos que são conhecidos por robôs.

O termo robótica surgiu da palavra, de origem checa, robota, que significa “trabalho forçado”.

Os primeiros modelos de aplicações da robótica foram encontrados na antiga civilização grega, eram figuras com aparência humana e/ou animal, que usavam sistemas de pesos e bombas pneumáticas. As civilizações daquele tempo não tinham nenhuma necessidade prática ou econômica, nem nenhum sistema complexo de produtividade que exigisse a existência deste tipo de aparelhos. Cientistas árabes acrescentaram um importante e novo conceito à idéia tradicional de robótica, concentrando as suas pesquisas no objetivo de atribuir funções aos robôs que fossem de acordo com as necessidades humanas. O termo robótica ficou mundialmente conhecido a partir da publicação do livro “Eu, Robô”, escrito por Isaac Asimov.

Adaptive routing algorithm for load balancing in telecommunications networks

This review is about the "Adaptive routing algorithm for load balancing in telecommunications networks," written by ARAUJO, Aluízio FR and Vittoria, for explain an adaptive routing algorithm, the Q-Agents, based on the interaction of three learning strategies with a aim for provide better performance and quality of data traffic on telecommunications networks.

Containing of six chapters: Introduction, Routing in Networks Telecommunications, Q-Agents: An adaptive algorithm, Description of Experiments, Discussion and Conclusion. In eighteen pages the article shows the importance of routing in networks telecommunications, as a fundamental mechanism in the control operation of the network. Throughout the text, the author and justifies the applications through experiments involving the main operating parameters of the network: the traffic pattern, load level and topology.

The article has a clear and objective language, which explains the operation of a routing dynamic and distributed algorithms, comparing them with the collective behavior of ants to, with the implementation of the Q learning, develop a new standard for routing algorithms: The Agent-Q. The mathematical expressions aren’t used in excess, making the text easy to understand and the reading less tiring.

The experiments are cohesive and give a real fact to the performance test, unveil the main conflicting points with other routing technologies and presenting an exciting performance.

This article is highly recommended for network administrators, because shows the knowledge about new technologies in the area and contribute to a better understanding of the system that involves routing in telecommunications networks.

Algoritmo de roteamento adaptativo para o balanceamento de carga em redes de telecomunicações

A resenha proposta é sobre o artigo “Algoritmo de roteamento adaptativo para o balanceamento de carga em redes de telecomunicações”, escrito por ARAUJO, Aluízio F.R. e VITTORI, Karla que apresenta um algoritmo de roteamento adaptativo, o Agentes-Q, baseado na interação de três estratégias de aprendizagem com a finalidade de proporcionar um melhor desempenho e qualidade no tráfego de dados de redes de telecomunicações.

Disposto em seis capítulos: Introdução, Roteamento em Redes de Telecomunicações, Agentes-Q: Um algoritmo adaptativo, Descrição dos Experimentos, Discussão e Conclusão. Em dezoito páginas o artigo apresenta a importância do roteamento nas redes de telecomunicações, como mecanismo fundamental no controle de operação da rede. Ao longo do texto o autor fundamenta suas aplicações através de experimentos que envolvem os principais parâmetros de operação de rede: padrão de tráfego, nível de carga e topologia.

Com uma linguagem clara e objetiva, o artigo explica o funcionamento de um roteamento e dos algoritmos dinâmico e distribuído, comparando-os com o comportamento coletivo de formigas para, com a implementação da aprendizagem Q, desenvolver um novo padrão de algoritmos de roteamento: o Agentes-Q. As expressões matemáticas não são utilizadas em excesso, favorecendo a compreensão e tornando a leitura menos cansativa.

De uma forma concisa atribuem situações reais ao teste de desempenho, desvendando os principais pontos conflitantes com outras tecnologias de roteamento e apresentando valores de desempenho empolgantes.

Para os administradores de redes, a leitura desse artigo é altamente recomendada, pois além de despertar o conhecimento sobre novas tecnologias na área, colabora para uma melhor compreensão da sistemática que envolve o roteamento em redes de telecomunicações.

Profile of Robson

My name is Robson Junior, I'm 19 years-old and I was born in Natal/RN. I live with my mother, my stepfather and my sister. I always liked the technologic area, because of this I'm studying Science and technology in UFRN, and I want specialize me in engineering mechatronics. But I don’t have sure if I’ll continue in course. Currently, I do graphic design services for some companies, and besides being a good business it's something that I love. I like very much radical sports and my favorite sport is Le Parkour, which I practice for four years. At the weekends I like to go out with my girlfriend and training.

Profile of Alysson

Hello, my name is Alysson da Silva Rodrigues, I am Brazilian, born in Ribeirão Preto - SP, I'm 29 years old and live in Natal since 1997. My family is from Rio de Janeiro, between 1990 and 1997, I lived there. I think these experiences have helped me to better understand the differences and, perhaps for these changes, I consider myself a person of easy adaptation. My personal characteristics are loyalty, honesty, fellowship, integrity, authenticity, stubbornness, anxiety and impatience. As for my day-to-day work in COSERN as a Support Analyst and after go to the course of C&T. On weekends, I like to go to the beach or the club with my daughter, girlfriend and friends; go to church; playing for my God, watch movies ... I love music, especially religious ones. Why be so anxious, I do a daily exercise: to live one day at a time. I strive to live today the best possible way, leaving me to shape, to be happy and make those who are beside me happy.

Profile of Thomás

My name is Thomás, I'm 20 years old and I live in Natal city with my mother, grandmother and my sister. Currently, I'm studying Science and Technology, at the Federal University of the Rio Grande do Norte (UFRN) because I like technology and developing of software so much and I do part of a search project about Software Engineering. When I have a free time I like to stay with my friends having fun, go to the church, because I'm Christian and I like going out with my girlfriend. I like talking about sports, my favorite and the best sport in the world, I think, is basketball, but I like to swim and I'm attending a bodybuilding gym whenever I have time.
