Performance of Magnetic-Superconductor Non-Contact Harmonic Drive for Cryogenic Space Applications

open access: yesMachines, 2015
Harmonic drives are profusely used in aerospace mainly because of their compactness and large reduction ratio. However, their use in cryogenic environments is still a challenge. Lubrication and fatigue are non-trivial issues under these conditions.

Dynamic model of a harmonic drive in a toothed gear transmission system

open access: yesJournal of Vibroengineering, 2014
The present paper discusses certain aspects of dynamic modeling of the harmonic drive. In particular, a new original dynamic model of a harmonic drive has been proposed for a power transmission system. The model takes account of nonlinear changes in stiffness, as well as damping.

Hunting in the Ghaznavid State: Courtly Culture, Military Practices and Political Power

open access: yesHistory, EarlyView.
Abstract Hunting occupied an important place in the royal court culture of the Ghaznavid state (963–1186 CE). Ghaznavid hunting culture developed through the interaction of Turkic‐Islamic political traditions, Persianate models of kingship and local ecological settings. Rather than constituting a fully formalized institution, Ghaznavid hunting practice
