Extended Kalman Filter-Based 2D Pose Estimation for Omnidirectional Mecanum Robots via Sensor Fusion: A SO(2) Lie Group Formulation

open access: yesEngineering Proceedings
This article presents a 2D pose estimation method for an omnidirectional mobile robot with Mecanum wheels, using an extended Kalman filter (EKF) formulated on the Lie group SO(2).

Representations of a solvable Lie group on $\overline \partial _b$ cohomology spaces

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1986
This paper announces results to be published elsewhere. A triplet (\({\mathfrak g}\), j, \(\omega)\) of a completely solvable Lie algebra \({\mathfrak g}\), a linear operator j of \({\mathfrak g}\), such that \(j^ 2=-1\), and \(\omega\in {\mathfrak g}^*\) is called a normal j-algebra if a few conditions are satisfied. Such a triplet gives rise to a Lie

Recent Advancements in Bulk Processing of Rare‐Earth‐Free Hard Magnetic Materials and Related Multiscale Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
This article provides an overview of recent advancements in bulk processing of rare‐earth‐free hard magnetic materials. It also addresses related simulation approaches at different scales. The research on rare‐earth‐free magnetic materials has increased significantly in recent years, driven by supply chain issues, environmental and social concerns, and

Branching Laws for Some Unitary Representations of SL(4,R)

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
In this paper we consider the restriction of a unitary irreducible representation of type A_q(λ) of GL(4,R) to reductive subgroups H which are the fixpoint sets of an involution. We obtain a formula for the restriction to the symplectic group and to GL(2,

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Sustainable Synthesis of Bio‐Based Magnetic and Conductive Wood for Electromagnetic Interference Shielding Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation
