Conventional authentication systems identify a user only at the entry point. Keystroke dynamics can continuously authenticate users by their typing rhythms without extra devices. This article presents a new feature called cognitive typing rhythm (CTR) to continuously verify the identities of computer users. Two machine techniques, SVM and KRR, have been developed for the system. The best results from experiments conducted with 1,977 users show a false-rejection rate of 0.7 percent and a false-acceptance rate of 5.5 percent. CTR therefore constitutes a cognitive fingerprint for continuous. Its effectiveness has been verified through a large-scale dataset. This article ...

We describe a curriculum reform project that aims to improve the industrial engineering curriculum through a web-based learning environment that engages students in active and collaborative learning. This environment focuses on engineering problems solving, increased information technology content, and the higher order cognitive skills that are needed to be a successful engineering problem solver. We describe the status of this project, which has been implemented in two courses: an engineering economy course and a manufacturing systems engineering course. One of the objectives of this new environment is integration of the curriculum, and we discuss how links were created between these ...

In an effort to improve students' problem solving skills with information technology across the industrial engineering curriculum, we created an Internet based problem-solving environment. The module implemented for engineering economy presents a realistic problem that establishes connections with other courses. The design of the learning environment promotes metacognitive skill development by requiring students to explain each major problem solving action taken and to evaluate their own progress toward a solution. Experience in two successive semesters of a large introductory course indicates that information technology can be used effectively to create opportunities for students to collaboratively solve realistic engineering problems, thereby ...


Information Technology Based Active Learning: A Pilot Study For Engineering Economy, Sigurdur Olafsson, Mary Huba, John K. Jackman, Frank E. Peters, Sarah M. Ryan Jan 2003

Information Technology Based Active Learning: A Pilot Study For Engineering Economy, Sigurdur Olafsson, Mary Huba, John K. Jackman, Frank E. Peters, Sarah M. Ryan

We have recently designed a learning environment to add practical problem solving, increased information technology content, and active learning to industrial engineering courses. In particular, we have successfully implemented and tested a computer-based module for an undergraduate engineering economy course. In this module, students are required to formulate the problem, devise a plan of action, and derive a final solution using the domain knowledge acquired in class. In addition to improving understanding of the course material, the module is also designed to improve more general cognitive skills and specifically to enhance the metacognitive ability of the participating students. A prototype ...
