Community resilience in collaborative learning
(American Institute of Mathematical SciencesMathematics Department, University of Texas at Arlington; Department of Curriculum and Instruction, University of Texas at Arlington; Laboratoire de Biometrie et Biologie Evolutive, UMR CNRS 5558 Universite Claude Bernard Lyon 1, France, 2010-07)This paper introduces a simplified dynamical systems framework for the study of the mechanisms behind the growth of cooperative learning in large communities. We begin from the simplifying assumption that individual-based ... -
Comparative Analysis Of Various Continuous-time Deterministic Models Of Tumor-immune Interactions
(Mathematics, 2015)Cancer is historically a leading cause of death in the United States. In 2013,cancer was the second leading cause of death with 584,881 deaths \cite{CDC}.Having solely been responsible for 22.5\% of all deaths in 2013 ... -
Comparison of Point Estimators of Normal Percentiles
(University of Texas at ArlingtonDepartment of Mathematics, 1977-08)**Please note that the full text is embargoed** ABSTRACT: There are available several point estimators of the percentiles of a normal distribution with both mean and variance unknown. Consequently, it would seam appropriate ... -
