Because many students experience frustration during learning, it is important to develop affective strategies to support students’ coping with frustration in interactive learning environments. First, we must devise affect recognition models to detect student affect. Second, we need to determine when to intervene; these conditions are likely to be different for each student. To determine how muc...

when the parties enter into a contract, they are obliged to implement its obligations, but sometimes events occur that make it impossible to execute the contract or runtime status than the time of conclusion of the contract is fundamentally different. these events are referred to as legal excuses if eligible, the parties are exempt from the obligations and responsibilities. the most important l...

We study hard-core bosons on the honeycomb lattice in presence of anisotropic nearest-neighbor repulsive interactions. Using a quantum Monte Carlo (QMC) technique, we extract phase diagram model terms filling and anisotropy. At half-filling find dimer insulator near maximum anisotropy that is characterized by finite topological entanglement entropy $ln(2)/2$, indicative fractional Hall state fo...

An intelligent tutoring system is a computer-based self-learning system which provides personalized learning content to students based on their needs and preferences. The importance of a students’ affective component in learning has motivated adaptive ITS to include learners’ affective states in their student models. Learner-centered emotions such as frustration, boredom, and confusion are cons...

In spin-glass systems, frustration can be adjusted continuously and considerably, without changing the antiferromagnetic bond probability p, by using locally correlated quenched randomness, as we demonstrate here on hypercubic lattices and hierarchical lattices. Such overfrustrated and underfrustrated Ising systems on hierarchical lattices in d=3 and 2 are studied. With the removal of just 51% ...
