In order to comprehensively evaluate and improve the performance of the Rogowski coil electronic current transformer (RCECT), this paper presents a method for steady state characteristic and the dynamic characteristic test. The testing scenario is configured in an electromagnetic transient simulation software (PSCAD), then the digital signals are reproduced as analog signals by amplifiers. The sensor...
The rapid serial visual presentation (RSVP) paradigm is a method that can be used to extend the P300 based brain computer interface (BCI) approach to enable high throughput target image recognition applications. The method requires high temporal resolution and hence, generating reliable and accurate stimulus triggers is critical for high performance execution. The traditional RSVP paradigm is normally...
The VR-1 reactor is operated by the Czech Technical University in Prague more than 20 years. The reactor is utilized mainly for education and training purposes. Therefore, the Czech Technical University, as a reactor licensee, makes an effort to continuously improve the reactor equipment, instrumentation and the educational and training methodologies. It is the way of providing an effective education...
One of the most common environment tests is the shock testing, widely used to test the mechanical integrity and to ensure the quality and reliability of products.
