    Sammanfattning : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. LÄS MER

    Sammanfattning : Integral membrane proteins play a key role hormonal and neuronal signaling. Transmembrane helix (TM) proteins form about 27% of the human proteome. Furthermore, 44% of the human drug targets are receptors, and 19% of these are seven-transmembrane domain receptors (GPCRs), which constitute 4% of the entire protein-coding genome. LÄS MER
