1. DISTRIBUTION OF MAIZE SEED IN A SEEDING LINE PROTOTYPE USING MICROCONTROLLED DATA ACQUISITION SYSTEMS
ABSTRACT: The aim of this study was evaluate the longitudinal distribution of maize seeds using a seeding line prototype, whit a microcontroller data acquisition system, at different speeds and types of horizontal feeder discs. Initially it was constructed a prototype simulator of seeding line, in the laboratory, and mounted two systems of microcontroller da

2. System board to measures of gas-liquid two-phase flow / Sistema embarcado para medidas de escoamento bifasico gas-liquido
Two-phase flow gas-liquid are commonly found in nature and in various industrial activities. In this type of flow, the phases present can escape arranged in different spatial configurations in the duct, called regimes or flow patterns, the determination is critical for the design of two-phase flow systems. In this study, an indication of the flow pattern is

7. Simulador computacional para poços de petróleo com método de elevação artificial por bombeio mecânico
This work proposes a computer simulator for sucker rod pumped vertical wells. The simulator is able to represent the dynamic behavior of the systems and the computation of several important parameters, allowing the easy visualization of several pertinent phenomena. The use of the simulator allows the execution of several tests at lower costs and shorter time

8. Dimensioning spray systems attached to center pivots. / Metodologia para dimensionamento de um sistema de pulverização acoplável a pivô central.
Dimensioning methodology was developed to design and operate a spray system attached to a center pivot, for the purpose of applying chemical products as herbicides, fungicides, insecticides and fertilizers. Both a computer program and prototype equipment were developed. During the spray applications, the aerial structure of the center pivot system moved with
