Loudspeaker voice-coil temperature estimation
, 2008 The temperature in the voice-coil of a loudspeaker is an important variable in the sense of protection against failure. In order to estimate the temperature in the voice-coil an adaptive filter has been used. The adaptive filter utilises a system identification setup.

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023 Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...
