Initial boundary value problems for the Carleman equation
Computers & Mathematics with Applications, 1983 The author utilizes the theory of nonlinear evolution operators to investigate the coupled first order hyperbolic system \[ \partial u/\partial t+\partial u/\partial x+u^ 2-v^ 2=0\quad u(0,t)=g(t),\quad v(1,t)=h(t) \] \[ \partial v/\partial t-\partial v/\partial x+v^ 2-u^ 2=0\quad u(x,0)=u_ 0(x),\quad v(x,0)=v_ 0(x) \] He associates a nonlinear ...

An initial–boundary value problem for the Maxwell equations
Journal of Differential Equations, 2010 AbstractIn this paper, by using methods from complex analysis and quaternionic analysis, we investigate an initial–boundary value problem for the Maxwell equations and obtain the general solutions and solvable conditions of the problem respectively in different cases.

Exam‐level analysis of lecture capture viewing and student exam performance
FEBS Open Bio, EarlyView.This study asks how lecture capture relates to exam performance in biology courses with three noncumulative exams. Mixed‐effects modeling separated between‐students from within‐student effects on exam %. Students who watched more recordings earned higher grades, but viewing spikes above a student's own mean, consistent with cramming, predicted small ...

Dissipative initial boundary value problem for the BBM-equation
Electronic Journal of Differential Equations, 2008 This paper concerns a dissipative initial boundary value problem for the Benjamin-Bona-Mahony (BBM) equation. We prove the existence and uniqueness of global solutions and the decay of the energy as time tends to infinity.

Card games are effective tools to enhance foundation year health and safety inductions
FEBS Open Bio, EarlyView.A series of three card games was developed to actively deliver health and safety education to foundation year students. Most students reported positive responses regarding their enjoyment (89.9 %) and learning (74.7 %) from all games evaluated. Data revealed significant improvements in health and safety knowledge (P < 0.0001).

Initial boundary value problem for generalized Zakharov equations with nonlinear function terms
Boundary Value Problems, 2020 In this paper, we consider the initial boundary value problem for generalized Zakharov equations. Firstly, we prove the existence and uniqueness of the global smooth solution to the problem by a priori integral estimates, the Galerkin method, and ...
