This paper introduces empirical studies of visualizing Taiwan’s Intelligent Transportation Systems (ITS) knowledge maps and assessing academic performance. Social network analysis is applied to visualize ITS knowledge maps to quantify the strength of the connections between individuals or universities. The results from the empirical study show that the development of ITS research is very promis...

Abstract The remarkable ascent of entrepreneurship witnessed as a scientific field over the last 4 decades has been made possible by entrepreneurship’s ability to absorb theories, paradigms, and methods from other fields such economics, psychology, sociology, geography, even biology. respectability an academic discipline is now evidenced many starting borrow view. In present paper, seven exampl...

The relatively low% of students promoted and regularized in Operating Systems Course of the LSI (Bachelor’s Degree in Information Systems) of FaCENA (Faculty of Sciences and Natural Surveying Facultad de Ciencias Exactas, Naturales y Agrimensura) of UNNE (academic success), prompted this work, whose objective is to determine the variables that affect the academic performance, whereas the final ...

It is crucial to promote interdisciplinary research and recommend collaborators from different research fields via academic database analysis. This paper addresses a problem to characterize researchers’ interests with a set of diverse research topics found in a large-scale academic database. Specifically, we first use latent Dirichlet allocation to extract topics as distributions over words fro...

The academic performance of students is a topic that has attracted many educational administrators. Among the factors effective on improving the students' academic performance are the teachers' methods and their interaction with the students. Using direct observation, coding the teaching/learning process to determine the type of relationship, and analysis of quality were common during the 50s a...

Nonlocal Hamiltonians are used widely in first-principles quantum calculations; the nonlocality stems from eliminating undesired degrees of freedom, e.g., core electrons. To date, attempts to couple nonlocal systems to external electromagnetic (EM) fields have been heuristic or limited to weak or long wavelength fields. Using Feynman path integrals, we derive an exact, closed-form coupling of a...

A continuum constraint-free phase field model is proposed to simulate the magnetic domain evolution in ferromagnetic materials. The model takes the polar and azimuthal angles (ϑ1,ϑ2), instead of the magnetization unit vector m(m1,m2,m3), as the order parameters. In this way, the constraint on the magnetization magnitude can be exactly satisfied automatically, and no special numerical treatment ...

What is the maximum visibility attainable in double-slit interference by an electromagnetic field if arbitrary - but reversible - polarization and spatial transformations are applied? Previous attempts at answering this question for electromagnetic fields have emphasized maximizing the visibility under local polarization transformations. I provide a definitive answer in the general setting of p...
