Wafer-scale fabrication of two-dimensional beta-In2Se3 photodetectors
Marcel S. Claro, Justyna Grzonka, Nicoleta Nicoara +2
The epitaxial growth of two-dimensional (2D) material was obtained over 2-inches c-sapphire wafers using molecular beam epitaxy (MBE). Excellent quality of thick (90 n…
Benefiting from Linear Behaviour of a Nonlinear Reset-based Element at Certain Frequencies
Nima Karbasizadeh, Ali Ahmadi Dastjerdi, Niranjan Saikumar +2
This paper addresses a phenomenon caused by resetting only one of the two states of a so-called second order "Constant in gain Lead in phase" (CgLp) element. CgLp is a recently int…
Complex order control for improved loop-shaping in precision positioning
Niranjan Saikumar, Duarte Valério, S. Hassan HosseinNia
This paper presents a complex order filter developed and subsequently integrated into a PID-based controller design. The nonlinear filter is designed with reset elements to have de…
Robust Identification of Target Genes and Outliers in Triple-negative Breast Cancer Data
Pieter Segaert, Marta B. Lopes, Sandra Casimiro +2
Correct classification of breast cancer sub-types is of high importance as it directly affects the therapeutic options. We focus on triple-negative breast cancer (TNBC) which has t…
Estimating the thermally induced acceleration of the New Horizons spacecraft
André G. C. Guerra, Frederico Francisco, Paulo J. S. Gil +1
Residual accelerations due to thermal effects are estimated through a model of the New Horizons spacecraft and a Monte Carlo simulation. We also discuss and estimate the thermal ef…
Kolmogorov's Lagrangian similarity law newly assessed
Manuel Barjona, Carlos B. da Silva
Kolmogorov's similarity turbulence theory in a Lagrangian frame is assessed with new direct numerical simulations (DNS) of isotropic turbulence with and without hyperviscosity, whi…
Comparison of Four Space Propulsion Methods for Reducing Transfer Times of Crewed Mars Mission
A. G. C. Guerra, O. Bertolami, P. J. S. Gil
We assess the possibility of reducing the travel time of a crewed mission to Mars by examining four different propulsion methods and keeping the mass at departure under 2500 tonne,…
Root Finding by High Order Iterative Methods Based on Quadratures
Mario M. Graça, Pedro M. Lima
We discuss a recursive family of iterative methods for the numerical approximation of roots of nonlinear functions in one variable. These methods are based on Newton-Cotes closed q…
The energy cascade in grid-generated non-equilibrium decaying turbulence
P. C. Valente, J. C. Vassilicos
We investigate non-equilibrium turbulence where the non-dimensionalised dissipation coefficient scales as with $m\…
A note on comonotonicity and positivity of the control components of decoupled quadratic FBSDE
Gonçalo Dos Reis, Ricardo J. N. dos Reis
In this small note we are concerned with the solution of Forward-Backward Stochastic Differential Equations (FBSDE) with drivers that grow quadratically in the control component (q…
Probing the Flyby Anomaly with the Galileo Constellation
O. Bertolami, F. Francisco, P. J. S. Gil +1
In the last few years, the so-called flyby anomaly has been widely discussed, but remains still an illusive topic. This is due to the harsh conditions experienced during an Earth f…
Estimating radiative momentum transfer through a thermal analysis of the Pioneer Anomaly
O. Bertolami, F. Francisco, P. J. S. Gil +1
A methodology based on point-like sources is discussed, enabling a reliable estimate of the acceleration of the Pioneer 10 and 11 probes caused by thermal effects. A sensitivity an…
