Comparison of P-convexity, O-convexity and other geometrical properties [PDF]
, 2012 We study some properties of O-convex and P-convex spaces and give a new proof of the P(n)-convexity of ℓp sums of P(n)-convex spaces. Further we show using Ramsey’s theorem that the space Eβ is P-convex.

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Oligopoly Games With and Without Transferable Technologies [PDF]
In this paper standard oligopolies are interpreted in two ways, namely as oligopolies without transferable technologies and as oligopolies with transferable technologies.From a cooperative point of view this leads to two different classes of cooperative ...

Notes on the Schur-convexity of the Extended Mean Values [PDF]
, 2002 In this article, the Schur-convexities of the weighted arithmetic mean of function and the extended mean values are proved. Moreover, some inequalities involving the arithmetic mean, the harmonic mean, the logarithmic mean, and comparison between the ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

A note on the Serrin problem in the plane
Le Matematiche, 2008 We investigate the stability of the radial symmetry for the overdetermined Serrin problem in a planar convex set. More precisely, we prove that, whenever we properly perturb both the boundary conditions and the data, then a convex solution is “close” to ...

Decomposition of a convex polygon into convex polygons
Discrete Mathematics, 1979 AbstractLet P be a convex polygon of the euclidean plane, with p vertices. P shall be decomposed into ƒ convex polygons Pj(j=1,…,ƒ). A point A of the plane is a “vertex of the decomposed polygon P”, if A is a vertex of one of the Pj. Let ei(i⩾2) be the number of i-valent vertices of the decomposed polygon P.

Efficient and Robust Standing Postures of Quadruped Robots
Advanced Robotics Research, EarlyView.A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint
