CONTINUOUS SURVEILLANCE OF POINTS BY ROTATING FLOODLIGHTS [PDF]
International Journal of Computational Geometry & Applications, 2014 Let P and F be sets of n ≥ 2 and m ≥ 2 points in a plane, respectively. We study the problem of finding the minimum angle α ϵ [2Π/m, 2Π] such that one can install at each point of F a stationary rotating floodlight with illumination angle α, initially oriented in a suitable direction, in such a way that, at all times, every target point of P is ...

Illuminating the x-Axis by α-Floodlights. [PDF]
, 2021 Given a set S of regions with piece-wise linear boundary and a positive angle α < 90°, we consider the problem of computing the locations and orientations of the minimum number of α-floodlights positioned at points in S which suffice to illuminate the entire x-axis.

Irradiance characteristic of a small-scale solar simulator for testing thermal collectors [PDF]
E3S Web of Conferences, 2019 This paper describes the development of a small-scale solar simulator for research and educational purposes. The main goal is to provide a uniform and stable distribution of irradiation from a set of four floodlight halogen lamps, over a targeted area of
