- von Neumann machines are based on the processing/memory abstraction of human information processing.
- neural networks are based on the parallel architecture of animal brains.
Neural networks are a form of multiprocessor computer system, with
- simple processing elements
- a high degree of interconnection
- simple scalar messages
- adaptive interaction between elements
A biological neuron may have as many as 10,000 different inputs, and may send its output (the presence or absence of a short-duration spike) to many other neurons. Neurons are wired up in a 3-dimensional pattern.
Real brains, however, are orders of magnitude more complex than any artificial neural network so far considered.
Where can neural network systems help?
- where we can't formulate an algorithmic solution.
- where we can get lots of examples of the behavior we require.
- where we need to pick out the structure from existing data.

Can a 3 wire system create neutral voltages due to Harmonic distortion?
Yes, a 3 wire system can create neutral voltages due to harmonic distortion. Neutral voltages can also be caused by load imbalance between the two hots. It is normal for neutral to have a voltage differential relative to ground. Neutral is, after all, a current carrying conductor. In a well balanced system, however, there is little (theoretically zero) current in neutral.
Can the neutral conductor be downsized in a 3 phase electrical system?
Yes, you can reduce the neutral in a three phase system. you must figure the unbalanced current the neutral will carry and also make allowances for any harmonics that may be present.
How do you identify that in the system the neutral is floating or not?
do a continuity test between the neutral and the metal enclosure of the equipment containing the neutral. infinity reading [ open line ] indicates floating neutral. Steve sorensen jr
Condition of three phase in which there is no need of neutral?
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
Why neutral is not requied in 3 phase?
As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.
What is the difference between neutral point and earthing?
Earthing point is where conductor is directly connected to ground and its potential is always zero. Neutral is a return path in single phase system and in three phase system Neutral point will have zero potential if all the loads are balanced in the system. In un balanced three phase system even neutral point will have some potential

When a tax system is referred to as being neutral it implies that?
tax system is fair
Why the neutral cable takes high current than the phase lines in three phase installation?
In a properly balanced three phase system, there is negligible current on neutral. If there is substantial current on neutral, then the system is not balanced and/or something is wrong.
Can the neutral conductor be downsized in a 3 phase electrical system?
Yes, you can reduce the neutral in a three phase system. you must figure the unbalanced current the neutral will carry and also make allowances for any harmonics that may be present.
What is meant by neutral grounding reactor?
Neutral-earthing reactors or Neutral grounding reactors are connected between the neutral of a power system and earth to limit the line-to-earth current to a desired value under system earth fault conditions.
How do you identify that in the system the neutral is floating or not?
do a continuity test between the neutral and the metal enclosure of the equipment containing the neutral. infinity reading [ open line ] indicates floating neutral. Steve sorensen jr
What would be the effect on the neutral bar of a 3 phase D B if the main incoming neutral is lost?
A three phase delta system does not use a neutral in its operation.
Which wire is the neutral wire in a 110 volt system?
White.
What is line phase neutral?
Line, phase, neutral are terms used to describe the conductors in a three-phase system. The three live wires are called 'lines', and less correctly, 'phases'. Neutral is used for the fourth wire which in a balanced system carries no current.
Condition of three phase in which there is no need of neutral?
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
