Title: Project Scheduling with Enhancement and Replacement Policies
Abstract: The purpose of this study is to investigate how a CIO can use a model of software quality to guide the allocation of an organization's software development resources. The goal is to develop a simulation tool which can help a CIO to create and maintain the highest quality software portfolio.
To accomplish this, a Task Schedule Simulator utilizing Java, XML and Jira programming/modeling languages will be implemented. Task Schedule Simulator is a software-based simulator which produces an analyzable software portfolio using user defined quality and other specifications. In this study I will use the simulation to show the effects using different enhancement and replacement policies. These will help to analyze the optimum combinations for a given company's situation and needs.

Title: Understanding Hadoop and Big Data
Abstract: Increasingly, Organizations today are facing more and bigger data challenges. They have access to wealth of information, but they don't know how to get the value out of it because it is sitting in its most raw form or semi structured or unstructured format; and as a result they don't even know it's worth keeping. Hadoop is an open source software framework that supports data-intensive distributed applications. Instead of relying on a single expensive system, Hadoop enables distributed parallel processing of huge amounts of data across inexpensive servers

ACM WKU Chapter Meeting

Bryan Knowles presented a talk on Social Network Analysis. The following is the abstract:

Social Network Analysis, as a sub-subfield of Complex Systems Analysis, is concerned primarily with the use of models to represent, to explain, and to predict. How, then, do the models studied by Social Network Analysts differ from those by other Analysts? or, more importantly, how are they the same?
Intuitive as they are, I will take us through the history and development of Social Network models, speaking only briefly on their many possible applications.

WKU Annual High School Programming Contest

The Department of Computer Science at WKU held the annual High School Programming Contest on April 19th and the Gatton Academy Programming Contest on April 24th. The contests are sponsored by the Department of Computer Science, Ogden College, and WKU.

Seven teams from four high schools in Kentucky participated in the contest. The schools were Barren County High School, Bowling Green High School, Nelson County High School, and Warren Central High School. Each team consists of up to three students.

The first, second and third place winning teams of the High School contest were Nelson County, Warren Central, and Barren County, respectively. Each member of the first-place winning team (Chandler Young and Aaron Brown) from Nelson County received a $1,000 scholarship.

Three teams (each with up to three students) from the Gatton Academy participated in the Gatton contest. Each member of the first-place winning team (Sam Dong and Akhil Ghanta) received a $1,000 scholarship.

The annual High School programming contest attracts the attention of high schools throughout Kentucky. It also brings excellent students to the Computer Science Program at WKU. Congratulations to all the students who participated.

Lucy Cheng - Hybrid Methods for Feature Selection

Abstract: Feature selection is one of important data preprocessing steps in data mining. The feature selection problem involves finding a feature subset such that a classification model built only with this subset would have better predictive accuracy than model built with complete set of features. In this study, we propose two hybrid methods for feature selection. The best features are selected through either the hybrid methods or existing feature selection methods. Then the reduced dataset is used to build classification models using five classifiers. The classification accuracy was evaluated in terms of the Receiver Operating Characteristic (ROC) curve performance metric. The proposed methods have been shown empirically to improve the performance of existing feature selection methods.

Thesis defense of Ahmed Alsalama

A Hybrid Recommendation Framework based on Association Rules

Recommendation systems are widely used in e-commerce applications. The engine of a current recommendation system recommends items to a particular user based on user preferences and previous high ratings. Various recommendation schemes such as collaborative filtering and content-based approaches are used to build a recommendation system. Most of current recommendation systems were developed to fit a certain domain such as books, articles, and movies. We propose a hybrid recommendation framework to be applied on two dimensional spaces (User x Item) with a large number of Users and a small number of Items. Moreover, our proposed framework makes use of both favorite and non-favorite items of a particular user. The proposed framework is built upon the integration of association rules mining and the content-based approach. The results of experiments show that our proposed framework can provide accurate recommendations to users.

    Four CS graduate students won 2nd prize in the 2011 "Idea State" competition held April 23rd in Lexington. The competition, sponsored by the Commonwealth of Kentucky, aims to encourage entrepreneurial ideas and economic development. Team members and participants, from left to right, are project leader Sindhu Murthy, team coach and CS Prof. David Erbach, Soujanya Ananta, WKU Center for Entrepreneurship Director Prof. Wil Clouse, Pratyusha Challa, WKU Event Director Dr. Krist Schell, and Ian Burchett. The students' project, named GetWellQuick, arose from a class project in CS 560 Software Engineering. It is a design for a smart phone application to facilitate communication between hospitals and patients who have recently been released but must continue to take treatments.

  • April 7, 2011
    The GetWellQuick team from CS 560 (Software Engineering) visit Bowling Green's famous ice cream store Chaney's Dairy Barn to celebrate their "Idea State" success. The team entered the WKU stage for Kentucky's Idea State entrepreneurial competition with a project called GetWellQuick. GetWellQuick is a design for a smart phone application which helps promote communication between hospitals, physicians, and patients who have recently been released from intensive care. The improved communication aims to allow patients to be released earlier. This in turn allows patients to recuperate faster in familiar surroundings, and allows hospitals to increase utilization of expensive facilities. The team estimated that if 10% of Kentucky patients could be released from hospitals 1/2 day earlier, this could save approximately $1 million annually in health care delivery costs.
