Item Epileptic seizure detection and prediction based on continuous cerebral blood flow monitoring - A review(2015) Tewolde, Senay (TTU); Oommen, Kalarickal; Lie, Donald Y.C. (TTU); Zhang, Yuanlin (TTU); Chyu, Ming Chien (TTU)Epilepsy is the third most common neurological illness, affecting 1% of the world's population. Despite advances in medicine, about 25 to 30% of the patients do not respond to or cannot tolerate the severe side effects of medical treatment, and surgery is not an option for the majority of patients with epilepsy. The objective of this article is to review the current state of research on seizure detection based on cerebral blood flow (CBF) data acquired by thermal diffusion flowmetry (TDF), and CBF-based seizure prediction. A discussion is provided on the applications, advantages, and disadvantages of TDF in detecting and localizing seizure foci, as well as its role in seizure prediction. Also presented are an overview of the present challenges and possible future research directions (along with methodological guidelines) of the CBF-based seizure detection and prediction methods.Item Misconception of Abstraction: When to Use an Example and When to Use a Variable?(2022) Du, Hanxiang; Xing, Wanli; Zhang, Yuanlin (TTU)Abstraction, which is considered the most important computational thinking skill, can be learned from programming or computational thinking learning activities. We implemented a 8-week long course to teach high school students statistics and programming. A pre- and post-test was designed to measure students’ understandings of computing and statistics. This work reports some interesting observations we made on students’ misconception of abstraction while examining students’ responses to test questions.
