It is about the construction of a sputtering system, through use cold plasma reactor, for deposition metallic thin films. Basically, this system works by ejecting atoms material (target) bombardment argon ions. This process takes place ionization gas, which has its ions accelerated towards target and when they collide with material, ejection occurs, these separate are deposited on substrate, fo...

Among one of the main problems affecting Brazilian agriculture, we can mention transport water, since in many places it is necessary to lift and other areas. Equipment such as motor pumps being used. However, they present a high cost purchase equipment, addition using non-renewable sources. Aiming get around this fact, use hydraulic ram becomes viable alternative, low-cost equipment whose funct...

The BOROZAR-P boronizing paste is used for thermo chemical treatment of steel machine tools and parts for enhancing their wear-resistance, i.e. extending their useful life-time. Boronizing in this case leads to hardening of the thermally treated surfaces. This new method comprises the formation of wearand corrosionresistant surface layer with minimum loss of time and expenses. The thus obtained...

There is a consensus that conventional continuous demand distribution methods are not appropriate for forecasting replacement parts. However, many forecasting tools available in market still use them. This work presents an application of the Poisson distribution to forecast the needs of electronic spare parts. Using basic stock management notions and usual concepts of reliability, availability ...

We describe the design concepts of the modular humanoid robot Myon, which can be disassembled and reassembled during runtime. The body parts are fully autonomous in a threefold sense: they all possess their own energy supply, processing power, and a neural network topology which allows for stand-alone operation of single limbs. The robot has especially been designed for robustness and easy main...

The actual need for rising the productivity and flexibility of the manufacturing systems requires the use of new technologies and methodologies. Particularly, Flexible Manufacturing Cells (FMC) are the field where better results can be obtained. FMC are highly adaptable to changes in the market and in the product, due to their flexibility. This flexibility only is possible if we use programmabl...
