The Seidel morphism of Cartesian products [PDF]

Algebraic & Geometric Topology, 2009
We prove that the Seidel morphism of $(M \times M', ω\oplus ω')$ is naturally related to the Seidel morphisms of $(M,ω)$ and $(M',ω')$, when these manifolds are monotone. We deduce that any homotopy class of loops of Hamiltonian diffeomorphisms of one component, with non-trivial image via Seidel's morphism, leads to an injection of the fundamental ...

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

Two preservation results for countable products of sequential spaces [PDF]

, 2007
We prove two results for the sequential topology on countable products of sequential topological spaces. First we show that a countable product of topological quotients yields a quotient map between the product spaces.

K-g-Fusion Frames on Cartesian Products of Two Hilbert C*-Modules

Mathematics
In this paper, we introduce and investigate the concept of K-g-fusion frames in the Cartesian product of two Hilbert C*-modules over the same unital C*-algebra. Our main result establishes that the Cartesian product of two K-g-fusion frames remains a K-g-

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.

FUCA: a Frame to Prevent the Generation of Useless results in the Dataflows Based on Cartesian Product for Convolutional Neural Network Accelerators [PDF]

International Journal of Information and Communication Technology Research
One of the most important issues in the design of CNN accelerators pertains to the accelerator's ability to effectively leverage the available opportunities in the type and processing of input data, and the task of achieving this objective mostly lies ...

Connectivity of Cartesian product graphs

Discrete Mathematics, 2006
Let \(n(G)\), \(\kappa(G)\), \(\lambda(G)\) and \(\delta(G)\) be the order, connectivity, edge-connectivity and minimum degree of a (di-)graph, respectively. In addition, let \(G_1\times G_2\) be the Cartesian product of two (di-)graphs \(G_1\) and \(G_2\). If \(G_1,G_2\) are two connected graphs, then the authors prove that \(\kappa(G_1\times G_2)\geq\

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

The homology groups of the Cartesian product $\Omega_{n_1}(m_1)\times \Omega_{n_2}(m_2)$

Researches in Mathematics
The paper continues the investigation of the spaces of complex-valued perfect splines $\Omega_n(m)$. These spaces were introduced as generalization of the spaces $\Omega_n$, the topology of which has been studied by V.I. Ruban, V.A. Koshcheev, A.M. Pasko.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...
