awesome-courses

List of awesome university courses for learning Computer Science!

A full port of the Epanet modeling library to Java, as a basis for our software platform's network analysis capabilities. This is a complete rewrite of the C language code to a portable, modern and extensible Java library that is hardware- and operating system-independent. The port is a full Epanet engine implementation, including the regular hydraulic and water quality simulation and fully integrating the MSX multi-species extension library.

car-price-prediction-system

Technologies: Nutch 1.6, MapReduce in Java, Mahout. For selling a used car, its price can be predicted by giving some attributes. e.g. Car Model, total miles, engine type. Trained data will be provided to our system to predict the price for new data. Used Nutch to crawl car data from 52 states which is on craigslist.org. Over 0.3 million records were fetched. The content was then pruned using two MapReduce Jobs. The first MapReduce cleaned the data removing unwanted unicode symbols and incomplete data (information without car model or total miles or engine or price). The Second MapReduce extracted the required attributes and emitted in tsv format. This tsv was then provided to a Naïve Based Classifier in Mahout. A classification model was built from the training data. This models predicts the price when attributes like car model model, miles, engine was provided.

Open Source Libraries for High Performance Scientific and Technical Computing

dataretrieval

This R package is designed to obtain its water quality sample data, streamflow data, and metadata directly from either the USGS NWIS (National Water Information System), but it allows for user-supplied text files as inputs. The program is designed to ingest the data directly into R and structure them into file structures suited for EGRET analysis.

egret

An R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method Weighted Regressions on Time, Discharge, and Season (WRTDS)

online-k-clustering

This project implements online-k-clustering algorithm as mentioned in this paper(http://cseweb.ucsd.edu/~dasgupta/291/lec6.pdf). It produces REALTIME k-clustering on an infinite stream of data. It is implemented on top of twitter storm and uses cassandra as database. It deals with 2-dimensional matrices and clusters in Euclidean space.
