Parameterising Arbitrary Shapes via Fourier Descriptors for Evidence-Gathering Extraction

, 1998
According to the formulation of the Hough transform it is possible to extract any shape that can be represented by an analytic equation with a number of free parameters.

Dipole‐Engineered Conductive Additives for Ultrastable Interphase Evolution in High‐Areal‐Capacity Silicon Anodes

Advanced Functional Materials, EarlyView.
In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Territorial development. A new approach to development processes for the economies of the developing countries

INTERthesis, 2013
This article seeks to show how the elements of a (flexible and adaptable) model of territorial development, whose roots are anchored in the analysis of coordination among pre-capitalist actors, can take on a more concrete form in developing economies ...

The Fourier Engine

IEEE Access, 2018
Each combustion chamber of the Fourier engine is open to multiple cylinders, which have pistons connected to crankshafts that rotate at different rates. The displacements of the individual cylinders and the relative phases of the pistons are selected according to a Fourier approximation of a prescribed time dependence of the volume of the combustion ...

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Shape classification via image-based multiscale description [PDF]

, 2011
We introduce a new multiscale Fourier-based object description in 2-D space using a low-pass Gaussian filter (LPGF) and a high-pass Gaussian filter (HPGF), separately.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.
