OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
Chaotic attractors from border-collision bifurcations: stable border fixed points and determinant-based Lyapunov exponent bounds
D. J. W. Simpson
The collision of a fixed point with a switching manifold (or border) in a piecewise-smooth map can create many different types of invariant sets. This paper explores two techniques…
Assessment of the Local Tchebichef Moments Method for Texture Classification by Fine Tuning Extraction Parameters
Andre Barczak, Napoleon Reyes, Teo Susnjak
In this paper we use machine learning to study the application of Local Tchebichef Moments (LTM) to the problem of texture classification. The original LTM method was proposed by M…
Appsent A Tool That Analyzes App Reviews
Saurabh Malgaonkar, Chan Won Lee, Sherlock A. Licorish +2
Enterprises are always on the lookout for tools that analyze end-users perspectives on their products. In particular, app reviews have been assessed as useful for guiding improveme…
An analysis of binary microlensing event OGLE-2015-BLG-0060
Y. Tsapras, A. Cassan, C. Ranc +83
We present the analysis of stellar binary microlensing event OGLE-2015-BLG-0060 based on observations obtained from 13 different telescopes. Intensive coverage of the anomalous par…
Parallax of OGLE-2018-BLG-0596: A Low-mass-ratio Planet around an M-dwarf
Youn Kil Jung, Andrew Gould, Andrzej Udalski +63
We report the discovery of a microlensing planet OGLE-2018-BLG-0596Lb, with preferred planet-host mass ratio . The planetary signal, which is chara…
