Persistent luminescence from triplet excitons in organic molecules is rare, as fast non-radiative deactivation typically dominates over radiative transitions. This work demonstrates that the substitution of a hydrogen atom derivative phenanthroimidazole with an N-phenyl ring can substantially stabilize excited state. stabilization converts material without phosphorescence emission into molecula...

Providing appropriate cues to users when interacting with objects in immersive virtual environments (IVEs) is a difficult task. In addition to individual user differences, environmental factors, and task-specific requirements, the technological complexity of the current state of the art in haptic feedback further increases the difficulty. Though the technology continues to improve, we are still...

A theoretical solution is presented for the forced convection heat transfer of a viscoelastic fluid obeying the Giesekus constitutive equation in a concentric annulus under steady state, laminar, and purely tangential flow. A relative rotational motion exists between the inner and the outer cylinders, which induces the flow. A constant temperature was set in both cylinders, in this study. The f...

Good prooling is a major issue in extracting performance from parallel programs. We report on a novel synthesis of sequential cost-centre prooling and state-of-the-art parallel simulation for the pure functional language Haskell that promises to provide detailed and accurate information about parallel Haskell programs. Exploiting simulation also improves the quality of sequential cost centre pr...

in this paper we study the relationships existing between total measurability in variation and gould type fuzzy integrability (introduced and studied in [21]), giving a special interest on their behaviour on atoms and on finite unions of disjoint atoms. we also establish that any continuous real valued function defined on a compact metric space is totally measurable in the variation of a regula...
