Due to its working modes, the Switching Mode Power Supply (SMPS) has low electromagnetic compatibility with other systems, such as Langmuir probes used in ion-source accelerators for heating plasma. Its high-frequency Electromagnetic Interference (EMI) is analyzed for its bias power suppl y of its core snubber. Located in the same HV pole of the accelerator, the EMI of SMPS lets its Langmuir probes...
Background Patients with migraine often have impaired somatosensory function and experience headache attacks triggered by exogenous stimulus, such as light, sound or taste. This study aimed to assess the influence of three controlled conditioning stimuli (visual, auditory and gustatory stimuli and combined stimuli) on affective state and thermal sensitivity in healthy human participants. Methods...
This paper introduces a robust and reliable method of human body recognition for visual surveillance systems. The method is developed based on the skeleton of moving object, which can be got by an improved thinning algorithm. In the paper we first describe some thinning algorithms for binary images, including OPTA thinning algorithm, Zhang's thinning algorithm and Rosenfeld's thinning algorithm. Comparing...
