    Energy Conditions of Built-In Inflation Models in f(T) Gravitational Theories by Gamal G. L. Nashed

    Published 2015-01-01
    “…We find the feasible constraints on the constants of integration and evaluate their possible ranges graphically for the consistency of these energy conditions for flat, closed, and open universes. We constrain the constants of integration for flat space-time from the inflation epoch while the closed and open universe constants are constrained from late universe.…”

    Universal cosmological solutions in Lovelock gravity by A. V. Nikolaev

    Published 2025-01-01
    “…Abstract This paper explores the Friedmann field equations within the framework of Lovelock gravity, a natural extension of Einstein’s gravity, focusing on both flat and open universes. Utilizing an approach based on independent Riemann tensor components, we derive generalized Friedmann equations for Lovelock gravity and categorize the solutions into Type I and Type II. …”

    A geography of virtual universities in Korea by Woo-Kung Huh

    Published 2007-12-01
    “…Information and communication technologies have relaxed time-honored practices of space-time synchronization in higher education, allowing even a new type of open universities, namely virtual universities. Seventeen virtual universities and colleges have been established in Korea since 2001. …”

    A novel framework for face recognition using robust local representation–based classification by Aihua Yu, Gang Li, Beiping Hou, Hongan Wang, Gaoya Zhou

    Published 2019-03-01
    “…Such an algorithm is expected to avoid the overfitting problem. The open-universe test on labeled faces in the wild data sets shows that the recognition rate of the proposed system can reach 95% with a recall rate of 80%, which is best among those representation-based classification face recognition systems.…”
