Implementation of a laser-truss based telescope metrology system at the Large Binocular Telescope
, 2020 Large ground-based telescopes are prone to perturbations caused by environmental factors that affect the mechanical structure of the telescope that can cause collimation loss and image quality degradation.

Hoghton’s camera and telescope
International Journal of Engineering Science, 2006 The third-order aberration formulae we have proved in a previous paper, starting from Fermat's principle and from the idea of stigmatic paths, are here applied to analyze and to project Houghton's cameras and Houghton-Cassegrain's telescopes. The final values of the radii of the two-lens corrector are obtained taking into account also the thickness of ...

Recent Results from the Telescope Array Experiment
, 2014 The Telescope Array Experiment (TA) is the northern hemisphere's largest detector of ultra-high-energy cosmic rays (UHECRs). Built to measure the UHECR chemical composition, arrival-direction anisotropy, and energy spectrum for $E > 1$~EeV, TA's ...

The method of combinatorial telescoping
Journal of Combinatorial Theory, Series A, 2011 We present a method for proving q-series identities by combinatorial telescoping, in the sense that one can transform a bijection or a classification of combinatorial objects into a telescoping relation. We shall illustrate this method by giving a combinatorial proof of Watson's identity which implies the Rogers-Ramanujan identities.

LIGHT ABERRATION IN OPTICAL ANISOTROPIC SINGLE-AXIS MEDIUM
East European Journal of Physics, 2017 The entrainment of the light flux by a uniaxial anisotropic medium and its influence on the measurement of stellar aberration are analyzed. The influence of the entrainment of the light flux by an isotropic medium on the measurement of stellar aberration
