Read MoreWhat are amphibious fishes? Can they live outside water?
The fishes that can survive without water for a good amount of time are known as amphibious fishes. Convergent evolution plays an important role in these species, as the next generation species receives analogous structures that have similar function but were not present in the last generation.Many fishes are amphibious, which means they can naturally survive out of the water. These fishes have developed limbs or use lateral undulation (that is, wave-like movement patterns that act to propel an animal forward) for terrestrial locomotion. They leave water bodies for many reasons like escaping predators, low oxygen environments etc.Ancient fish had ...
Read MoreWhat is Flaring and what are the different types of Horn antennas?
To improve the radiation efficiency and directivity of the beam, the waveguide should be provided with an extended aperture so as to make the abrupt discontinuity of the wave into a gradual transformation, so that all the energy in the forward direction gets radiated. This can be termed as Flaring. Flaring is done to provide greater directivity and narrower beam width. The types of horn antennas depend on how they are flared.Sectoral HornThis type of horn antenna, flares out in only in one direction. Flaring in the direction of Electric vector produces the sectorial E-plane horn. As well, flaring in ...

Read More8085 program to convert an 8 bit number into Grey number
In this program we will see how to find the gray code from an 8-bit number.Problem StatementWrite 8085 Assembly language program to convert an 8-bit number stored at 8000H to its equivalent gray code. The result will be stored at 8050H.DiscussionIn this program we are converting binary to gray code. The procedure is simple. At first we have to shift the content to the right, then perform XOR operation with the sifted content and the actual content. Thus we will get the gray code. For an example if the number is ABH, then the binary value will be (1010 1011), ...
