Maxflow

This software implements the popular maxflow algorithm described by Boykov and Kolmogorov in the paper: "An Experimental Comparison of Min-Cut/Max-Flow Algorithms for Energy Minimization in Computer Vision", published in IEEE Transactions on Pattern Analysis and Machine Intelligence, September 2004.

Chemistry assignment by CS , B.tech

This is the assignment of Bioremediation by B.tech which explains Bioremediation with the help of introduction, applications, principle, types etc for eg-Natural attenuation or intrinsic bioremediation: Bioremediation occurs on its own without adding anything. b)Biostimulation: Bioremediation is spurred on via the addition of fertilizers to increase the bioavailability within the medium. In situ bioremediation: It involves treating the contaminated material at the site. b)Ex situ bioremediation: It involves the removal of the contaminated material to be treated elsewhere.

Mathematics-III

Acellus Integrated Mathematics III, taught by Patrick Mara, is the last course of a three-part series that includes algebra, geometry, probability, and statistics. This high school math pathway is patterned after an approach typically seen internationally. Take out your Notebook and a pen, Get your Kumbhojkar or any other reference books pickup solved examples and start solving them. For M3, practice is the key. The more you practice the less chances of making mistakes. It's not a theory subject so avoid reading Maths.
