    • ROTATIONAL SPEED MEASUREMENT AND ANGULAR POSITION REFERENCE FOR A CRYOGENIC PROPELLANT ELECTRIC PUMP 

      Author: Petrucha V.; Ripka P.
      (FEI, Slovak University of Technology, 2015)
      Hall sensors with an analog output were used as rotational speed sensors and provided an angular position reference for other diagnostics measurements during a cryogenic Propellant Electric Pump (PEP) test campaign. ...
    • A Busbar Current Sensor With Frequency Compensation 

      Author: Grim, V.; Petrucha, V.; Ripka, P.
      (IEEE, 2017)
      DC/AC yokeless galvanically insulated electric current sensors are required for applications, e.g., in automotive and aerospace engineering, where size, weight, and/or price are strictly limited. A busbar current sensor ...
    • Efficient Structure from Motion by Graph Optimization 

      Author: Havlena, Michal; Torii, Akihiko; Pajdla, Tomáš
      (Springer Berlin Heidelberg, 2010)
      We present an efficient structure from motion algorithm that can deal with large image collections in a fraction of time and effort of previous approaches while providing comparable quality of the scene and camera ...
