Compact electrical generators for diesel driven generating sets [PDF]

open access: yes, 2002
This thesis explores two approaches for converting rotating mechanical power from diesel engines into electrical power of fixed frequency and voltage. Advances in high energy permanent magnets and power electronics are enabling technologies that provide ...

Characterized Ecoflex Polydimethylsiloxane (PDMS) Hybrids for Advanced Flexible Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Ecoflex–PDMS hybrids are systematically characterized to identify an optimal composition that balances stretchability, optical transparency, and plasma bonding, enabling multifunctional applications in stretchable microfluidics, flexible sensing, and soft robotics.

Problems with laplace operator on topological surfaces

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
This work highlights the problems related to the Laplace operator on topological surfaces such as Mobius strip, Klein bottle and torus. In particular, we discuss oscillations on the surface of the Mobius strip, eigenfunctions and eigenvalues of the ...

Endpoint boundedness of toroidal pseudo-differential operators

open access: yesOpen Mathematics
In this note, we prove that the toroidal pseudo-differential operator is bounded from L∞(Tn){L}^{\infty }\left({{\mathbb{T}}}^{n}) to BMO(Tn){\rm{BMO}}\left({{\mathbb{T}}}^{n}) if the symbol belongs to the toroidal Hörmander class Sρ,δn(ρ−1)∕2(Tn×Zn){S}_{

Product-cordial index and friendly index of regular graphs [PDF]

open access: yesTransactions on Combinatorics, 2012
Let $G=(V,E)$ be a connected simple graph. A labeling $f:V to Z_2$ induces two edge labelings $f^+, f^*: E to Z_2$ defined by $f^+(xy) = f(x)+f(y)$ and $f^*(xy) = f(x)f(y)$ for each $xy in E$. For $i in Z_2$, let $v_f(i) = |f^{-1}(i)|$, $e_{f^+}(i) = |(f^

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

open access: yesAdvanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

The Archetypal Invariant of Cyclicity: Syntax, Myth and Gender as Topological Models of Continuity Based on the Example of Proto-Turkic Contacts and the Cult of Osiris

open access: yesPolylinguality and Transcultural Practices
This interdisciplinary study investigates the universal archetypal principle of cyclicity, which manifests synchronously in historically and geographically unrelated systems.

Multilators on a 3-Torus: A framework for high-dimensional coupled oscillators

open access: yes
The classical Kuramoto oscillator typically involves a single scalar state variable representing the phase of each oscillator. In contrast, swarmalators, an extension of the framework of Kuramoto oscillators, incorporate two coupled variables per unit ...

Cohomological Donaldson-Thomas theory for local systems on the 3-torus [PDF]

open access: yes
This paper studies the Cohomological Donaldson-Thomas theory of G-local systems on the topological three torus. Using an exponential map we prove cohomological integrality for GLₙ-local systems using the statement of cohomological integrality for the ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

open access: yesAdvanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
