An algorithm for choosing a rational sequence for machining a part on a machine with a tool magazine is proposed using the drilling operations example. The algorithm is based on the analysis of all possible options and the calculation of the time spent on each of them. In this respect, the working tool (drill) change is considered, if it is necessa...

The paper studies three forms of the pulse-width modulated (PWM) signal which is used to power the electromagnetic vibration drives of resonance-type vibrating machines. On the basis of a comparative analysis of the characteristics of PWM signals using the root mean square deviation for the time domain, the nonlinear harmonics (distortions) coeffic...

The electrical supply system in most underdeveloped nations is incredibly undependable. The country’s existing distribution system has experienced regular power outages due to population growth, industrial expansion, rough terrain, and a long-distance transmission network. The conventional approach to centralized generation and transmission is fail...

Rural irrigation could be challenging in regions without proper access to electricity. In many remote places of Nepal, where the irrigation takes place in the vicinity of a river stream, a river water pump or coil pump can be used to supply water from the lower river terrain to the field. Water powered coil pump is a reciprocating pump that operate...
