AbstrakPendulum terbalik memiliki pusat gravitasi yang berada diatas poros putar sehingga menyebabkan pendulum terbalik tidak seimbang. Suatu kendali khusus dibutuhkan agar pendulum seimbang dengan cara menggerakkan kereta beroda yang menjadi tumpuan dari pendulum. Penerapan pendulum terbalik dapat ditemui pada balancing robot. Tujuan dari penelitian ini adalah merancang bangun sebuah sistem pengendalian robot dengan dua roda menggunakan sistem kendali untuk membuat robot yang seimbang (balancing robot). Sistem ini mempunyai masukan akselerometer yang digunakan untuk mengukur percepatan sudut (m/s2) dan giroskop untuk mengukur kecepatan sudut (rad/s). Luaran dari akselerometer dan giroskop digabungkan dengan metode complementary filter untuk mendapatkan nilai sudut. Sudut yang diperoleh kemudian dibandingkan dengan set point yang nilainya 0o. Nilai selisih dari set point dan sudut complementary filter diolah menggunakan metode kendali Proporsional Integral Derivatif. Proses kendali PID ini diprogram pada Arduino IDE yang hasilnya diumpankan ke motor DC untuk mengatur kecepatan putar motor DC. Untuk arah putar motor DC ditentukan apabila sudut complementary filter kurang dari nol, maka motor akan berputar mundur. Sedangkan jika sudut complementary filter lebih dari nol, maka motor akan berputar maju. Nilai konstanta PID berdasarkan hasil tuning dengan metode Ziegler-Nichols metode osilasi adalah Kp=1.5, Ki=0.75, Kd=1.85 dan nilai koefisien pada algoritma complementary filter adalah a=0.96. Kata kunci—inverted pendulum, balancing robot, kendali PID, IMU, complementary filter Abstract Center of gravity’s inverted pendulum is located above its pivot point therefore inverted pendulum is unstable.

The purpose of this research is to design a system to control a two wheeled robot using the control system to balance it.The inputs are accelerometer to measure angular acceleration (m/s2) and gyroskop to measure angular velocity (rad/s). The output’s of accelerometer and gyroscope are fused by complementary filter algorithm method to get the actual angle. The actual angle is then compared to set point which is 0o. The differences between set point and actual angle are processed using Proportional Integral Derivative control method. The process of PID control is programmed using Arduino IDE which its result is fed to DC motors. The direction of DC motors are determined by two conditions, if actual angle less than zero then DC motors will spin backwards. Whereas if actual angle more than zero then DC motors will spin forward.

Published: January 2017

O estágio atual de degradação da Amazônia fez emergir, em âmbito internacional, um debate sobre seu futuro e sobre as ações que contribuem para a destruição ou para a conservação da floresta. Diversos grupos travam uma luta simbólica neste debate, através da qual buscam legitimação para seus projetos e para suas formas de utilização dos recursos. Neste trabalho, buscou-se construir um quadro analítico em que fossem contempladas as diversas matrizes discursivas empregadas na discussão acerca dos rumos da Amazônia brasileira, levando em consideração as propostas de diferentes atores e elaborações teóricas sobre os conceitos de desenvolvimento, preservação e sustentabilidade. Foram identificadas, desta forma, quatro matrizes discursivas: o discurso desenvolvimentista, o discurso da mercantilização da natureza, o discurso preservacionista e o discurso socioambiental. Palavras-chave: Amazônia; sustentabilidade; conflito ambiental; políticas públicas. Abstract: The current Amazon’s degradation state resulted in the emergence of an international debate on its future and on the actions that contribute to forest’s destruction or conservation. Several groups find themselves in a symbolic struggle around this debate, through which they reach for legitimacy for their projects and the different uses of resource. In this paper we tried to build an analytical approach in which the various discursive matrices utilized in the discussion on the future of the Brazilian Amazon were contemplated. This has been done considering the proposals of different agents and theoretic elaborations on the concepts of development, preservation and sustainability. In this way, four discursive matrices were identified – the developmentalist discourse, the nature’s mercantilist discourse, the preservationalist discourse and the socio-environmentalist discourse – that, in different political conjectures act with more or less influence over the elaborated policies for each region, with direct effects over its ecosystems and inhabitants.

Published: January 2017

O texto analisa as lutas de representações em torno da construção de identidades ligadas ao espaço geográfico da nação brasileira e da cidade de Novo Hamburgo (RS) através do seu principal jornal, O 5 de Abril, no período de 1927, momento de sua emancipação, até 1945, final da Segunda Guerra Mundial e da ditadura do Estado Novo. Este período foi marcado pela construção de versões acerca destas duas identidades e de sua disseminação através da imprensa. As duas versões apresentavam conflitos especialmente focados no fato de a cidade ser representada por signos que remetiam ao processo de imigração alemã, e à nação, por signos que remetiam à mestiçagem. Tais conflitos acirraram-se no momento em que o Brasil entrou na Segunda Guerra Mundial contra a Alemanha. Palavras-chave: cidade; identidade nacional; imprensa. Abstract: This is an analysis of the struggle over representations involving the construction of identities rooted in the geographical space of the nation of Brazil and the city of Novo Hamburgo using the city’s main newspaper, “O 5 de Abril”, which was published from 1927, when the city was officially recognized, until 1945, which marked the end of the Second World War and of the Estado Novo dictatorship in Brazil. This period was marked by the construction of different versions of these two identities and their massification by the media. These versions were in conflict, specifically focused on the fact that the city was represented through signs that refer to the process of German immigration, while there presentation of the nation was through signs referring the intermixing of races. These conflicts intensified when Brazil entered the Second World War against Germany. Keywords: city, national identity, the press.

Authors: Netto Vinicius M. , Krafta Romulo 
Published: January 2017

O artigo traça crítica a indicadores urbanos usuais, baseados na intensidade de presença de características ou propriedades, e aponta a necessidade de indicadores de comportamento definidos pelo conhecimento do impacto da trama de propriedades espaciais sobre as dinâmicas da cidade – indicadores verdadeiramente de desempenho, aptos a avaliara cidade como fenômeno dinâmico e relacional, no qual seus componentes e dimensões têm efeitos uns sobre os outros. Indicadores capazes de capturar, por exemplo, os modos como diferentes padrões de morfologia podem impactar a vida microeconômica, a sociabilidade urbana ou o ambiente em níveis de influência sobre tendências de menor ou maior dependência veicular na movimentação intraurbana. Para tanto, lança os fundamentos teóricos e metodológicos para um novo sistema de indicadores arranjados em dois eixos: metaindicadores de desempenho(equidade, eficiência, qualidade espacial e sustentabilidade) e dimensões urbanas(morfologia, dinâmica socioeconômica, limiares urbanos e relações cidade–ambiente). Palavras-chave: desempenho e comportamento urbano; indicadores sistêmicos; planejamento. Abstract: The present work proposes concepts and indicators intended to grasp features and effects of urban form; in fact, systemic indicators defined to tackle cityscapes as relational processes whose constituents are pervaded by mutual effects. Firstly, it brings a critique of indicators found in the literature, asserting that most indicators are feature indicators rather than performance indicators. Secondly, it advances theoretical and methodological grounds for new indicators geared to assess the impacts of urban structure on aspects of social life, equity in the access to jobs and facilities, the efficiency of locational patterns in economic interactions, and the sustainability of urban reproduction. Thirdly, anew set of indicators is proposed and arranged in two major groups: (i) performance indicators (spatial quality, urban equity, efficiency and sustainability), and (ii) meta-indicators for urban dimensions (general indicators of urban morphology, socioeconomy, criticality, and city environment relations). Finally, the paper discusses possibilities of application and further development, and brings mathematical definitions of the systemic indicators. Keywords: urban performance; systemic indicators; criticality.
