Research on infants’ ability to discriminate speech sounds with different directions of spectral tilt can be used to optimise the frequency response of hearing aids being fitted to very young infants. In the current study, infants were presented with a fricative contrast with either a positive or negative spectral tilt, or in unmodified form. The results showed 6-month-olds were able to discrim...

This work proposes and studies a new repetitive controller for discrete-time systems which are required to track or to attenuate periodic signals. The main characteristic of the proposed controller is its passivity. This fact implies closed-loop stable behavior when it is used with discrete-time passive plants. The work also discusses the energetic structure, the frequency response and the time...

We consider a quantity-setting duopoly market where firms lack perfect knowledge of the market demand function. They use estimated and therefore misspecified demand functions instead and determine their optimal strategies from the corresponding subjective payoff functions. The central issue of this paper is the question under which conditions a firm can learn the true demand function as well as...

It is common for researchers to evaluate interventions by having the participants answer standardized questions before and after, and measuring the effect of the intervention as a statistical difference between the two. There is a risk that the results of such a calculation will be misleading due to the subject interpreting the response scales differently on each occasion. This risk has previou...

The dependence and independence of input signal amplitudes for Generalised Frequency Response Functions(GFRF’s) are discussed based on parametric modelling.
