Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

Advanced Intelligent Systems, EarlyView.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

K-Rb Fermi-Bose mixtures: vortical states and sag [PDF]

, 2004
We study a confined mixture of bosons and fermions in the quantal degeneracy regime with attractive boson-fermion interaction. We discuss the effect that the presence of vortical states and the displacement of the trapping potentials may have on mixtures

SSZ‐13‐Zeolith mit Isolierten Co2+‐Zentren als ein Effizientes und Beständiges Katalysatorsystem für die Nichtoxidative Ethandehydrierung

Angewandte Chemie, EarlyView.
Für die nichtoxidative Ethandehydrierung zu Ethen wurden Katalysatoren mit isolierten Co2+‐Spezies in den 6MR‐ (Co2+‐Z2) und 8MR‐Fenstern ([Co(OH)]+‐Z) eines SSZ‐13‐Zeolithen hergestellt. Die Co2+‐Z2‐Spezies zeigten im Vergleich zu den [Co(OH)]+‐Spezies eine unerwartet hohe Ethenbildungsgeschwindikeit.

Accounting for Spacers in the Mechanical Calculation of Flexible Wires for Overhead Lines and Switchgears

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2019
The mechanical calculation of flexible wires of overhead lines and switchgears, in which in-phase or phase-to-phase spacers are installed, is under consideration. Spacers are considered as concentrated loads acting on the split phase.

Impacts from SSTs, ENSO, stratospheric QBO and global warming on Hurricanes over the North Atlantic [PDF]

, 2009
Processes affecting hurricane development over the North Atlantic like the El Niño Southern Oscillation (ENSO), the stratospheric Quasi-Biennial Oscillation (QBO) and Sea Surface Temperatures (SSTs) are discussed. Global coupled climate model simulations

Nachhaltige Ammoniak‐Elektrosynthese Gekoppelt mit Glycerin‐Valorisierung Mittels Eines Adaptiven Dreikomponenten‐Katalysators

Angewandte Chemie, EarlyView.
Ein Cu‐Ni‐W‐Dreikomponenten‐Katalysator ermöglicht eine effiziente Umwandlung von Nitrat zu Ammoniak unter gepulster Elektrolyse. Kombinierte experimentelle und theoretische Studien führen seine Leistungsfähigkeit auf die Synergie der Komponenten und regulierte Zwischenprodukte zurück.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Sag and Tension of 275 kV Transmission Line using Catenary

International Journal of Electrical, Energy and Power System Engineering, 2019
This research will develop a catenary method to determine the sag and tension analysis on the 275 kV transmission line conductors. The catenary method is dependent on the equation of the weight of the conductor, the maximum tensile stress of the ...

A Unified Analysis of Stochastic Optimization Methods Using Jump System Theory and Quadratic Constraints

, 2017
We develop a simple routine unifying the analysis of several important recently-developed stochastic optimization methods including SAGA, Finito, and stochastic dual coordinate ascent (SDCA).
