Second-order mixed-moment model with differentiable ansatz function in slab geometry

, 2017
We study differentiable mixed-moment models (full zeroth and first moment, half higher moments) for a Fokker-Planck equation in one space dimension.

The Complexity of Online Bribery in Sequential Elections (Extended Abstract) [PDF]

Electronic Proceedings in Theoretical Computer Science, 2019
Prior work on the complexity of bribery assumes that the bribery happens simultaneously, and that the briber has full knowledge of all voters' votes. But neither of those assumptions always holds. In many real-world settings, votes come in sequentially,

Moment-Based Relaxation of the Optimal Power Flow Problem

, 2014
The optimal power flow (OPF) problem minimizes power system operating cost subject to both engineering and network constraints. With the potential to find global solutions, significant research interest has focused on convex relaxations of the non-convex

The Efficiency of First (GEE1) and Second (GEE2) Order “Generalized Estimating Equations” for Longitudinal Data

Jurnal Ilmu Dasar, 2014
The approach of GEE focuses on a linear model for the mean of the observations in the cluster without full specification  the distribution of full-on observation. GEE is a marginal model where is not based on the full likelihood of the response, but only

Biped robot walking control on inclined planes with fuzzy parameter adaptation [PDF]

, 2010
The bipedal structure is suitable for a robot functioning in the human environment, and assuming assistive roles. However, the bipedal walk is a poses a difficult control problem.
