Analytical and Experimental Investigation of a Curved Piezoelectric Energy Harvester
Sensors, 2022 Piezoelectric energy harvesters have traditionally taken the form of base excited cantilevers. However, there is a growing body of research into the use of curved piezoelectric transducers for energy harvesting. The novel contribution of this paper is an

Frontiers in Ecology and Evolution, 2023 The biomechanics of limb bone curvature are complex, and though anterior curvature clearly exhibits some relationship with behavior, the mechanisms shaping it and its biomechanical purpose remain unclear. Among both Neanderthals and humans, anterior limb

Abnormal Seebeck Effect in Vertically Stacked 2D/2D PtSe2/PtSe2 Homostructure
Advanced Science, 2022 When a thermoelectric (TE) material is deposited with a secondary TE material, the total Seebeck coefficient of the stacked layer is generally represented by a parallel conductor model.

Advanced Electronic Materials, 2023 2D transition‐metal dichalcogenide (TMDC) materials are promising candidates with excellent thermoelectric (TE) properties owing to their low dimensionality in electronic and phonon transport. However, the considerable coupling of the Seebeck coefficient

Nonpositivity: Curvature vs. curvature operator [PDF]
Proceedings of the American Mathematical Society, 2004 It is shown that there exist closed Riemannian manifolds M M all of whose sectional curvatures are negative, but

Quantitative Analysis of Seed Surface Tubercles in Silene Species
Plants, 2023 In the Caryophyllaceae, seed surfaces contain cell protrusions, of varying sizes and shapes, called tubercles. Tubercles have long been described in many species, but quantitative analyses with measurements of size and shape are lacking in the literature.

Lane Detection Algorithm Using LRF for Autonomous Navigation of Mobile Robot
Applied Sciences, 2021 This paper proposes a lane detection algorithm using a laser range finder (LRF) for the autonomous navigation of a mobile robot. There are many technologies for ensuring the safety of vehicles, such as airbags, ABS, and EPS.

Blindness to Curvature and Blindness to Illusory Curvature [PDF]
i-Perception, 2018 We compare two versions of two known phenomena, the Curvature blindness and the Kite mesh illusions, to highlight how similar manipulations lead to blindness to curvature and blindness to illusory curvature, respectively. The critical factor is a change in luminance polarity; this factor interferes with the computation of curvature along the contour ...

A Short Review on the Finite Element Method for Asymmetric Rolling Processes
Metals, 2021 Several studies on asymmetric rolling processes use the Finite Element Method (FEM) to predict material deformation and optimize process parameters, such as rolls’ forces and torques.

Mean Curvature in the Light of Scalar Curvature [PDF]
Annales de l'Institut Fourier, 2020 We formulate several conjectures on mean convex domains in the Euclidean spaces, as well as in more general spaces with lower bounds on their scalar curvatures, and prove a few theorems motivating these ...
