Option 4 : 1, 2 and 3

Distributed winding:

For obtaining smooth sinusoidal emf waveform, conductors are placed is several slots under a single pole. This armature winding is known as distributed winding.

  • It reduces emf
  • It also reduces harmonic emf and so waveform is improved
  • It also diminishes armature reaction
  • Even distribution of conductors helps for better cooling
  • The core is fully utilized as the conductors are distributed over the slots on the armature periphery


Fractional pitch winding:

When the number of slots per pole per phase is an integer, the winding is the integer slot winding but when the number slots per pole per phase is a fractional number the winding we refer as fractional slot winding.

  • It is practicable only with the double-layered winding
  • It reduces both the emf and harmonics

Consider the following solution to the producer-consumer synchronization problem. The shared buffer size is . Three semaphores empty, full and mutex are defined with respective initial values of 0, and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R, and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait ( ) and signal ( ). Producer: Consumer: do {         wait (P) ;         wait (mutex) ;         //Add item to buffer         signal (mutex) ;         signal (Q) ; } while (1) ; do {          wait (R) ;          wait (mutex) ;          //Consume item from buffer          signal (mutex) ;          signal (S) ; } while (1) ;   Which one of the following assignments to P, Q, R and S will yield the correct solution?

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
