Heat exchangers are one of the most used and important devices in modern industry, as well as in residential sector. There is no ideal heat exchanger. As a result, there are many types of heat end mass exchangers. The design differs according to the capacity, temperature, pressure, type of work fluids and other factors. As several different types o...

The toroidal cutting edge, also called corner cutter, is a combination of the cylindrical-frontal milling cutter and the spherical head milling. The paper follows at generating the optimal trajectory for making the finished product with the toroidal cutting edge without having to use the flat end mill and the ball nose end mill. This trajectory is ...

In order to solve complex decision-making problems, MCDM has recently known a fast development. One of the main differences between the decision models consists in the way of evaluating the numeric and the non-numeric data that interfere while solving a problem. If the number of the criteria is not high and the evaluation contains both quantitative...
