A Preliminary Study on the Yang-cheon-cheok (量天尺) in the Late Joseon Dynasty [PDF]
Journal of Astronomy and Space Sciences, 2015 We investigated the six remaining Yang-cheon-cheoks (量天尺), which were first described in the Veritable Record of King Sukjong (肅宗實錄). These woodblock sundials from Korea are structurally very similar to a Gyupyo (圭表, gnomon) or an altitude sundial and ...

Geometry and the Restoration of Ancient Sundials: Camera Obscura Sundials in Cava de’ Tirreni and Pizzofalcone [PDF]
, 2017 Sundial is a special solar device which signals exclusively, every day of the year, when the Sun crosses the local meridian, at South, thus working as a perpetual calendar on which you can read the date, rather than the daily time.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Accurate modeling of vibrating machines equipped with Neidhart springs is challenging due to the strong nonlinearities introduced by the elastomer–metal torsional elements and the constraints imposed by their kinematic arrangement. Multibody modeling methodologies for such vibrating machines are often computationally demanding, thus limiting ...

Construction of sundials via vectors [PDF]
, 2019 A method based on oblique projection is presented for construction of sundials. The derived formulas are classical, but usage of vectors and projections renders a coherent presentation rather than a number of special cases. The presented work is aimed to
