Systematic Learning and Pedagogy Through a Modular, Progressive‐Based Simulation Modeling Framework for Complex Systems

open access: yesSystems Engineering, EarlyView.
ABSTRACT Smart Transportation Systems (SmTS) will exceed complex systems with their classification as complex, sociotechnical, and AI‐based systems. Possessing a toolkit that helps systemically understand, analyze, and assess these systems will be advantageous in the early stages of the systems engineering (SE) lifecycle, and Agent Based Models (ABMs ...

Existence of positive solutions for singular eigenvalue problems

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we discuss the existence, nonexistence, and multiplicity of positive solutions for a class of singular eigenvalue problems. Some of our theorems are new, while others extend earlier results obtained by Zhang and Kong [12].

Nonexistence of equivariant degree one maps

open access: yes, 1987
We establish the nonexistence of equivariant maps between some classes of manifolds carrying G G -free actions and spheres, whose degree is prime to | G | \left | G \right | , the order of

100 Years of Element Zero: Andreas von Antropoff's Neutronium and the Naming of the Neutron

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Congratulations to the 100th Anniversary of the publication of Andreas von Antropoff's element 0, “–“! This contribution provides a historical account of the concept of element zero and the naming of the neutron. The concept of element zero is 100 years old, having a first documented appearance in a 1926 publication by Andreas von Antropoff, while the ...
