Male European badger churrs: insights into call function and motivational basis by Charlton, BD, Newman, C, Macdonald, DW, Buesching, CD

“…In this study, we used infra-red video cameras and remote audio recorders to document seasonal and contextual variation in male European badger (Meles meles) churr production over a 24-month period, and acoustic analysis based on source-filter theory to examine whether churr acoustic structure varies according to the caller’s arousal state and identity. …”

Optimal spectral tracking--with application to speed dependent neural modulation of tibialis anterior during human treadmill walking. by Brittain, J, Catton, C, Conway, B, Nielsen, J, Jenkinson, N, Halliday, D

“…The approach adopts adaptive filter theory while retaining a spectral focus, thus remaining compatible with much of the current literature. …”

Gyroscopic data fusion via a quaternion based complementary filter by Smith, P, Frost, A, Probert, P

“…The main contribution of this paper is to combine existing complementary filter theory with quaternion attitude representation. …”
