Extension of the Side Distance Measurement Aspect Ratio in the Measurement of a Slot or Bore Using a Commercial Laser Triangulation Sensor [PDF]
SensorsWe propose a new commercial laser triangulation sensor modification to enable the measurement of slots or bores side distance. The study showed the possibility of extending the sensor depth range for a slot or bore side distance measurement using a ...

Testing ToF Sensors for Use in Obstacle Detection Systems [PDF]
Problemy Mechatroniki, 2022 ToF (Time of Flight) sensors have been gaining popularity in recent times as a cheap and accurate way to take distance measurements. They may prove to be a key component of obstacle detection systems in the near future.

Phonological Distance Measures* [PDF]
Journal of Quantitative Linguistics, 2009 Phonological distance can be measured computationally using formally specified algorithms. This work investigates two such measures, one developed by Nerbonne and Heeringa (1997) based on Levenshtein distance (Levenshtein, 1965) and the other an adaptation of Dunning's (1994) language classifier that uses maximum likelihood distance. These two measures

Invariants in problems of pattern recognition and control of states of complex objects
Вестник Дагестанского государственного технического университета: Технические науки, 2022 Objective. The aim of the study is to build emulators of the main sensors of a small spacecraft (SC).Method. The quality of recovery is determined by the standard deviation (RMS) of the data from the standards.

Self-Mixing Laser Distance-Sensor Enhanced by Multiple Modulation Waveforms
Sensors, 2022 Optical rangefinders based on Self-Mixing Interferometry are widely described in literature, but not yet on the market as commercial instruments. The main reason is that it is relatively easy to propose new elaboration techniques and get results in ...
