Unscented Kalman Filter Based 3D Localization of Outdoor Mobile Robots [PDF]

open access: yes한국정밀공학회지, 2020
This paper proposes a practical method, for evaluating 3-D positioning of outdoor mobile robots using the Unscented Kalman Filter (UKF). The UKF method does not require the linearization process unlike conventional EKF localization, so it can minimize ...

Span–conditioned allomorphy and late linearization: Evidence from the Classical Greek perfect

open access: yesGlossa, 2021
Data from the perfect in Classical Greek provide empirical evidence for inwardly– and outwardly–sensitive span–conditioned allomorphy and indicate the need for a post–Vocabulary Insertion linearization process.

Linear Invariants for Linear Systems

open access: yesCoRR, 2021
A central question in verification is characterizing when a system has invariants of a certain form, and then synthesizing them. We say a system has a $k$ linear invariant, $k$-LI in short, if it has a conjunction of $k$ linear (non-strict) inequalities -- equivalently, an intersection of $k$ (closed) half spaces -- as an invariant.

Contact with Friction Between 3D Beams with Deformable Circular Cross Sections

open access: yesEngineering Transactions, 2015
In this paper, contact with friction between three-dimensional elastic beams with deformations at the contact zone is analysed. It is assumed that the analysed beams undergo large displacements, although the strains remain small and the cross sections of

Chain Reduction via Substitution: Evidence from Mayan

open access: yesGlossa, 2021
We argue that deletion is not the only way that chain links created by A′-movement can be affected at PF. Chain links can also be substituted by a morpheme.

Review article of Waltraud Paul’s New Perspectives on Chinese Syntax (2015)

open access: yesGlossa, 2016
Taking Paul (2015) as a starting point, this article discusses different approaches concerning the contribution made by Chinese to general syntactic theory and typology.

Optimization of an Inductive Displacement Transducer

open access: yesSensors, 2023
This paper presents the optimization of an inductive displacement transducer or linear variable differential transformer (LVDT). The method integrates design software (SolidWorks 2023), simulation tools (COMSOL Multiphysics), and MATLAB. The optimization

Combination of Digital Second-Order Linearization Technique and DPD Compensation Technique - Concept and Results

open access: yes, 2023
In this paper, a single stage broadband power amplifier operating at 3.5 GHz central frequency is linearized in simulation by the technique that combines two linearization approaches: 1. the digital technique that uses the second-order baseband nonlinear
