Snore sound (SnS) classification can support a targeted surgical approach to sleep related breathing disorders. Using machine listening methods, we aim to find the location of obstruction and vibration within a subject’s upper airway. Wavelet features have been demonstrated to be efficient in the recognition of SnSs in previous studies. In this work, we use a bag-of-audio-words approach to enhance...
Aphasia is an acquired language disorder resulting from damage to language related networks of the brain, most often as a result of ischemic stroke or traumatic brain injury. Within the European Union, over 580000 people are affected each year. Both assessment and treatment of aphasia require the analysis of language, in particular of spontaneous speech. Factoring in therapy and diagnosis sessions,...
The systems and the software in the domain of industrial trucks are becoming increasingly complex due to the rapidly increasing demand for more functionality. This leads to an even faster rising effort for manual verification activities. Therefore, automated testing techniques need to be introduced into the verification process.In this work, a search-based test generation technique has been adapted...
In electrical systems parasitic capacitances are forming resonant circuits in combination with the inductances of the system. Each inverter switching operation is stimulating common-mode oscillations in these resonant circuit which can lead to critical overvoltages at the motor terminals. These voltages could damage the insulation system of the electrical machine and reduce the service life of the...
A combination of passive, non-invasive and nonintrusive smart monitoring technologies is currently transforming healthcare. These technologies will soon be able to provide immediate health related feedback for a range of illnesses and conditions. Such tools would be game changing for serious public health concerns, such as seasonal cold and flu, for which early diagnosis and social isolation play...
The quality of the singing voice is an important aspect of subjective, aesthetic perception of music. In this contribution, we propose a method to automatically assess perceived singing quality. We classify monophonic vocal recordings without accompaniment into one of three classes of singing quality. Unprocessed private and non-commercial recordings from a social media website are utilised. In addition...
In order to improve the grid-connected inverters for industry or solar fields, for example, we have done intensive research with future control methods using direct current control for such usually pulse-width modulation (PWM) controlled inverters. This paper investigates whether current measurements via sigma-delta converters are good and fast enough for the high dynamic performance of a direct current...
