Identification and dynamical properties of asteroid families
; ; Carruba, Valerio (Asteroids IV, 2015) [Capítulo de livro]
Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts ... -
Multi-criteria decision analysis of classrooms standardisation in a higher education institution
Salomon, Valério A.P.; ; Marins, Fernando Augusto Silva (International Journal of Business and Systems Research, 2016) [Trabalho apresentado em evento]
As any other organisation, a higher education institution (HEI) has to manage operations and processes when transforming inputs in outputs. Furniture used in laboratories, offices, and even in the classrooms is an important ... -
The fate of particles in the dynamical environment around Kuiper-Belt object (486958) Arrokoth
; Winter, O. C. (Astrophysics and Space Science, 2022) [Artigo]
The contact binary Kuiper-Belt object (486958) Arrokoth, targeted by the New Horizons mission, has a unique slope pattern, which is a result of its irregular bilobate surface shape and high spin period. Thus, some peculiar ... -
New hybrid AHP-QFD-PROMETHEE decision-making support method in the hesitant fuzzy environment: An application in packaging design selection
Porto De Lima, Byanca; Da Silva, Aneirson Francisco ; Marins, Fernando Augusto Silva (Journal of Intelligent and Fuzzy Systems, 2022) [Artigo]
This paper presents a new hybrid decision-making support method (New Hesitant Fuzzy AHP-QFD-PROMETHEE II Method), which jointly uses the Analytic Hierarchy Process (AHP), the Quality Function Deployment (QFD) and the ... -
Analysis of physical phenomena associated with asteroid deect by kinetic impact
Chagas, Bruno; De A. Prado, Antonio F.B. ; Winter, Othon Cabo (Proceedings of the International Astronautical Congress, IAC, 2021) [Trabalho apresentado em evento]
We have as objective for the present work, to study the use of a kinetic impact technique as a way to deect asteroids that may present some risk of collision with the Earth at a certain moment, or even the interest in ... -
APOPHIS - Effects of the 2029 Earth's encounter on the surface and nearby dynamics
Valvano, G.; Winter, O. C. ; Sfair, R. ; MacHado Oliveira, R. ; ; Moura, T. S. (Monthly Notices of the Royal Astronomical Society, 2022) [Artigo]
The 99942 Apophis close encounter with Earth in 2029 may provide information about asteroid's physical characteristics and measurements of Earth's effects on the asteroid surface. In this work, we analysed the surface and ... -
