Classification Of Eeg Signals Of User States In Gaming Using Machine Learning, Chandana Mallapragada
Classification Of Eeg Signals Of User States In Gaming Using Machine Learning, Chandana Mallapragada
Masters Theses
"In this research, brain activity of user states was analyzed using machine learning algorithms. When a user interacts with a computer-based system including playing computer games like Tetris, he or she may experience user states such as boredom, flow, and anxiety. The purpose of this research is to apply machine learning models to Electroencephalogram (EEG) signals of three user states -- boredom, flow and anxiety -- to identify and classify the EEG correlates for these user states. We focus on three research questions: (i) How well do machine learning models like support vector machine, random forests, multinomial logistic regression, and …
Design And Implementation Of Digital Information Security For Physical Documents, Pengcheng Wang
Design And Implementation Of Digital Information Security For Physical Documents, Pengcheng Wang
Masters Theses
The objective of this thesis is to improve the security for physical paper documents. Providing information security has been difficult in environments that rely on physical paper documents to implement business processes. Our work presents the design of a digital information security system for paper documents, called "CryptoPaper", that uses 2-dimensional codes to represent data and its security properties on paper. A special scanner system is designed for "CryptoPaper" which uses image recognition techniques and cloud-based access control to display plaintext of encrypted and encoded data to authorized users.
Collaboration Portal For Researchers At Eastern Illinois University, Fatemeh Khastkhodaardekani
Collaboration Portal For Researchers At Eastern Illinois University, Fatemeh Khastkhodaardekani
Masters Theses
This thesis addresses a need for an online collaboration environment for the researchers at Eastern Illinois University (EIU). As the solution, it provides a portal for researchers (students and faculties) who wish to explore and collaborate on projects based on ideas from those who may not have the necessary skills. This is considered to help developing projects based on the ideas as well as making teams, and teach different groups of people different perspectives. Therefore, it offers a learning environment. I started off by examining existing tools and methodologies to satisfy this purpose. As the result, the deliverable project is …
Mapping Spatial Thematic Accuracy Using Indicator Kriging, Maria I. Martinez
Mapping Spatial Thematic Accuracy Using Indicator Kriging, Maria I. Martinez
Masters Theses
Thematic maps derived from remote sensing imagery is increasingly being used in environmental and ecological modeling. Spatial information in these maps however is not free of error. Different methodologies such as error matrices are used to assess the accuracy of the spatial information. However, most of the methods commonly used for describing the accuracy assessment of thematic data fail to describe spatial differences of the accuracy across an area of interest. This thesis describes the use of indicator kriging as a geostatistical method for mapping the spatial accuracy of thematic maps. The method is illustrated by constructing accuracy maps for …
Enterprise Users And Web Search Behavior, April Ann Lewis
Enterprise Users And Web Search Behavior, April Ann Lewis
Masters Theses
This thesis describes analysis of user web query behavior associated with Oak Ridge National Laboratory’s (ORNL) Enterprise Search System (Hereafter, ORNL Intranet). The ORNL Intranet provides users a means to search all kinds of data stores for relevant business and research information using a single query. The Global Intranet Trends for 2010 Report suggests the biggest current obstacle for corporate intranets is “findability and Siloed content”. Intranets differ from internets in the way they create, control, and share content which can make it often difficult and sometimes impossible for users to find information. Stenmark (2006) first noted studies of corporate …
Customer Feedback Information System For Quality Improvement, Ke Wang
Customer Feedback Information System For Quality Improvement, Ke Wang
Masters Theses
This research addressed the basic needs for an effective customer feedback information system and the database technology to develop the system. It discussed the system concept and configuration of a typical customer feedback information system, database management technology, programming flow charts, program functions and capabilities. A proposed customer feedback information system consists of customer data inputs, database management system and outputs to various departments in an organization. With a user-friendly interface, database management system serves as an information management tool. It can process the feedback from customers and use the information in decision making. Thus, customer feedback can be promptly …
