These sources are typically characterized by a limited query capability compared to a relational data source. They may also be incomplete, and there may be redundancy among them. These features increase the challenge of scaling to answer queries in a mediator-wrapper architecture with a large num...

One of major reasons of failure of solder joints is known as the thermal fatigue. Also, The failure of the solder joints under the thermal fatigue loading is influenced by varying boundary conditions such as the material of solder joint, the materials of substrates(related the difference in CTE), the height of solder, the Distance of the solder joint from the Neutral Point (DNP), the temperatur...
