SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900?s, but the extreme low tem ....etc

hi guys,

i am a new user in this site and this seems to a good site.

and i am trying to do this mini project on blue tooth enabled temperature sensor.
i think it is an awesome idea but the thing is i am in my 2nd year only and my knowledge level in ECE is very limited. :(
i have managed to gather some material but can't make much of it.
so i am asking you my doubts hoping you will be patient and clear my doubts.
so here goes:
DOUBTS:

(1) the process starts off with a thermal s ....etc

Because of their excellent high temperature characteristics, Ni-based single-crystal alloys are used in applications where operating temperatures exceed 900ºC. The initiation of cracks under these conditions is generally associated with micro-scale porosities (typically between 10 and 20 microns). A rate-dependent crystallographic constitutive model in conjunction with a mass diffusion model has been used to study crack initiation in single crystal nickel-base superalloys, exposed to an oxidizing environment and subjected to ....etc

MPFI ( multi point fuel injection system ) Vs CRDI(Common rail direct injection system)

(Actually an open office format. Use open office to open it)
MPFI : mean multi point fuel injection system ie. in petrol engine for gaining more uniform Air Fuel blending fuel is injected at various point in the path of air. this tech is used in light weight car running on petrol. there is also milage improvement due to this.

but in case of DTSI(digital twin spark ignition) : the
engine cylinder consist of two no of spark plu ....etc
