This article deals with developing new modified algorithms of 40kb/s ADPCM. Beside the standard algorithm, three algorithms are developed to reduce the ADPCM distortion. The performances of all algorithms are evaluated with QAM signal at speed of 9.6kb/s. The outcomes demonstrate that the first proposed algorithm outperforms the other algorithms.

The paper describes some functionality extensions for a D.C. motor speed control system with PID controller used as a didactic unit. The extensions are made in two directions: one at a physical-hardware level and the other one at software development of numerical algorithms and graphical interface. Both developments have the aim to extend and to ge...

The CNC (Computer numerical control) is a machine that processes different kinds of materials at different types of precisions, determined by the system used to realize the transmission from the motor to the axes. In our project, we used the screw nut transmission because it offers a great precision and it has an optimal price-quality ratio.

The concept of cogeneration defines the simultaneous production with the same installation of electric and thermal energy (in the form of hot water or steam). High-efficiency cogeneration implies that cogeneration production should ensure primary energy savings of at least 10% compared to the reference values of separate production of electricity a...
