in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

Background: Many studies have shown that about 45-65% of multiple sclerosis (M.S) patients suffer from cognitive impairments. Semantic memory as one of the subcategories of cognition is quite important for effective communication. In the present study, category-semantic memory was studied in order to evaluate the semantic memory organization in normal individuals and MS patients. Methods: Nine...

Automatic short answer grading (ASAG) is the automated process of assessing answers based on natural language using computation methods and machine learning algorithms. Development of large-scale smart education systems on one hand and the importance of assessment as a key factor in the learning process and its confronted challenges, on the other hand, have significantly increased the need for ...
