Supercomputing on smartphones... New app came

The new software works in cases where the general form of a problem is known, but not the particulars. It has slider bars that allow users to set the values for which they want the problems solved.
Researchers in MIT's Department of Mechanical Engineering have developed software that can perform complex calculations in seconds on an ordinary smartphone that might otherwise be performed on a supercomputer. Although the software is for demonstration only, but it could pave the way for applications that let engineers perform complicated calculations in the field using their smartphones.
Although the phone requires a supercomputer to derive these initial equations, after that the phone would have the ability to execute them to a close approximation. According to the developers of the application, there are certain complex calculations that need to be performed in the field. While the general parameters of an equation might be known to them, they might not know certain specific measurements. These specific measurements will be entered into the smartphone.

Since the mathematical models on which these calculations rely apparently take up very little memory, many of such models can be stored, and any additional models can be downloaded from the field.

The software is available for download and it comes preloaded with models for nine problems. These problems include heat propagation in objects of several different shapes, fluid flow around a spherical obstacle, and the effects of forces applied to a cracked pillar.

Washing machine will run on junks... Indian brains made it

Sourabh Siyal and Tushar Agarwal, students of Christ College, designed a model which would pester people to take interest in environmental issues. Eco-wash, a washing machine was made out of junk material and ran on mechanical and kinetic energy, without the use of electricity.

"The junk materials include a discarded plastic bottle, which we used as a box to wash clothes. A pulley is attached to the plastic bottle to run the machine. The pulley moves with the help of kinetic energy and helps to wash clothes," explained Agarwal, who wants to be a scientific innovator.

"Our idea is to do away with electricity and come up with an alternative. The washing machine can be useful in big textile industries. We're planning to give our idea to one of India's leading garment manufacturing units," said Siyal, who too wanted to pursue research works in the field of science.

In another such example of innovation, four students of Outreach school, under the guidance of their Physics teacher developed an 'Earthquake predictor'. "The earthquake predictor is nothing but a borewell. The borewell is attached to a buzzer. The buzzer makes sound if the underground water level increases, which means that the movement of lava in the underground is moving at a faster rate, an indication of the likelihood of an earthquake. The fast movement of lava will force the water level to increase, which in turn will make the buzzer give out signals," said Subramanian K, a student.
