Existing information-measuring systems (IMS) do not fully correspond to the tasks of monitoring electric power installations (EPI) in terms their characteristics. The capabilities IMS have certain limitations regarding probability measurement results and degree invariance influence operational factors. This proves that for modern failure-free EPI technical operation, new diagnostic tools are de...

In this paper, an overview of the techniques applied to AC electric propulsion field has been done. Actual study cases of electric ship propulsion schemes are considered. An impartial comparison between three-level converters versus two-level converter from the viewpoint of electric ship propulsion requirements has been done. Diodeclamped three-level converters using direct torque control (DTC)...

Introduction: This study aims to determine the amount of hand-arm vibration transmitted from heavy electric destruction tools and the effect of using chisel with different lengths and shapes when demolishing concrete surfaces. Material and Methods: To evaluate the magnitude of hand-arm vibration on the left and right handles of two powerful electric demolition hammers commonly applied in Irani...

2) ELECTRICAL SAFETY a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if you...

Intense electric fields activate the mutagenic mechanism of a single guanine-cytosine base pair. Would they be able to induce a permanent mutation in real DNA? This question is addressed here by modeling a DNA-embedded fragment with state-of-the-art theoretical tools. We show how DNA can, in principle, be mutated if an appropriate electric field is applied.

with the aim of reducing cost of electricity consumption and peak load reduction, tools requirement for better managing electricity consumption have become inevitable in recent years. smart home has some equipment which are controllable and this ability is used for increasing comfort and minimizing electricity cost for residence. as a key component of smart home , electric vehicle(ev) ,increase...

The design of a full electric vehicle (or battery electric vehicle (BEV)) requires the development and optimization of a complete electric powertrain, including battery, power electronics, electric machine, sensors and control system. When designing an electrical platform, from the very beginning of the V-cycle, it is mandatory to rely on modelling and simulation tools in order to drive the mai...
