Pesquisa Eleitoral Maués - Dezembro/2015
#PESQUISA365 - Pesquisa Eleitoral Maués - Dezembro/2015
Objetivo: Avaliar a administração da Prefeitura de Maués e do Governo do Amazonas, identificar a intenção de voto para prefeito da cidade entre outras questões.
Metodologia e período de realização da pesquisa: Pesquisa do tipo quantitativa através de uma amostragem probabilística sistemática. As entrevistas foram realizadas por telefone (fixo ou móvel) conforme o banco de dados da Telemar, Vivo, Claro e Tim. O período de realização da pesquisa foi nos dias 10 e 11 de dezembro.
Tamanho da amostra: Foram realizadas 260 (duzentas e sessenta) entrevistas.
Margem de erro e grau de confiabilidade: A margem de erro máxima estimada é de 6,1%, para mais ou para menos, com um grau de confiabilidade de 95%. Isso significa que se fossem feitas 100 entrevistas com a mesma metodologia, 95 estariam dentro da margem de erro prevista.
A REVIEW :MODELLING OF BRUSHED DC MOTOR AND VARIOUS TYPE OF CONTROL METHODS
This Review Paper introducing the modeling of Brushed DC motor and different PID control techniques. A brushed DC motor is commutated an internally which is electric motor designed to be run by a direct current power supply. A Brushed motors were the first commercially important application for convert electric power to driving mechanical loads, and DC power distribution systems were used for more than 100 years to operate motors in commercial and industrial Applications. A conventional brushed DC Motor consist basically two parts,first one is the stationary body of the motor called the Stator and the other one is inner part which rotates producing the movement called the Rotor or“ Armature†for DC motors. For the motion control of DC motor in almost applications, PID controller is used. The PID controllers have a long history in control engineering and they have been proven to be robust, simple and stable for many real world applications. Roughly, P action is related to the present error, I action is based on the past history of error, and D action is related to the future behavior of the error. From estimation point of view P, D, and I correspond to filtering, smoothing and prediction problems respectively.This control mode is combination of the Proportional, the Integral, and the Derivative mode. This is most powerful but complex controller mode. It provides accurate and stable control of the three controller mode. It is recommended in system where the load changes frequently. The Three-term , PID controllers are probably the most widely used industrial controller. An Even complex industrial control systems may comprises a control network whose main control building block is a PID control module. The three-term PID controller has had a long history of use and has survived the changes of technology from the analogue era in to the digital computer control system age quite satisfactorily. It was the first controller to be mass produced for the high- range volume market that existed in the process industries.

Slides from my (controversial) presentation at the ILICA conference in NYC on 9/25/09. I made one small correction on slide 14 to reflect the feedback received during the presentation. I replaced ~15-20m, with ~15m, which does not change the substance of the controversy that I was relating about.
I also unpacked the animations so they will work on line.
Addvance slides - 2 pp (manhã)
Projeto integrado apresentado à Universidade Metodista de São Paulo no 2º semestre de 2015. Tema: A sustentabilidade e a sua relação com a publicidade - O consumo consciente: desperdício de alimentos.
Moulage exercício criativo
Relata o surgimento, origens e evolução da moulage ao decorrer dos séculos, bem como apresenta algumas técnicas de texturização.
