Estimation of coefficient of rolling friction by the evolvent pendulum method
A major objective of tribological researches is characterisation of rolling friction, due to various cases encountered in classical engineering applications, like gear transmissions and cam mechanisms or more recent examples met in bioengineering and biomedical devices. A characteristic of these examples consists in reduced dimensions of the contac...

System monitoring feedback in cinemas and harvesting energy of the air conditioning condenser
Our article monitors the degree of emotional involvement of the audience in the action film in theaters by measuring the concentration of CO2. The software performs data processing obtained dispersion sensors and displays data during the film. The software will also trigger the start of the air conditioning condenser where we can get harvesting ene...

Modelling pressure rolling of asymmetric rolling process
The paper presents a comparative analysis between experimental results and modelling in order to interpret the value of the contact pressure on the asymmetric longitudinal rolling. It is also intended action and the different behaviour of upper cylinder compared to the lower cylinder action in situations when both are driven, or only one operates. ...

Simulation of electrical and thermal fields in a multimode microwave oven using software written in C++
Due to multiple reflexions on walls, the electromagnetic field in a multimode microwave oven is difficult to estimate analytically. This paper presents a C++ program that calculates the electromagnetic field in a resonating cavity with an absorbing payload, uses the result to calculate heating in the payload taking its properties into account and t...

Integration of disabled people in an automated work process
Automation processes enter more and more into all areas of life and production. Especially people with disabilities can hardly keep step with this change. In sheltered workshops in Germany people with physical and mental disabilities get help with much dedication, to be integrated into the work processes. This work shows that cooperation between di...

Optical Gripper
With increasing automation, many work processes become more and more complex. Most technical products can no longer be developed and manufactured by a single department. They are often the product of different divisions and require cooperation from different specialist areas. For example, in the Western world, a simple coffee maker is no longer so ...

Simulation of defects on contactor coil
By definition, a coil is an electrical passive device, which have two terminals, use in electrical circuits to keep the power in magnetic field or to detect the magnetic fields. In winding process, is possible to appear different defects, or issues which can cause in time problems in functionality of products. In this paper, we will analyze two typ...
