Ruminating over Equalisation Levies

Ruminating on rumination.

H i H amilton et al. (1) reported some very interesting and important findings in their article “Default-Mode and TaskPositive Network Activity in Major Depressive Disorder: Implications for Adaptive and Maladaptive Rumination.” In the article, the authors explored dominance of the default-mode network (DMN) over the task-positive network (TPN) and how that dominance might be related to depress...

Environmental Levies, Distortionary Taxation and Increasing Returns

In this note, we introduce increasing returns to Bovenberg and Mooij’s (1994) model as generalised in Fullerton (1997) and use an example to show that (1) even with a distortionary labor tax, the optimal environmental levy is greater than the Pigouvian rate; (2) the difference between tax on the “dirty” good and the “clean” good is also greater than the Pigouvian tax; (3) under certain circumst...

Equalisation Tuning Method

The paper presents a novel tuning method for different types of controllers. Since the tuning method is trying to equalise the closed-loop response to the open-loop response, it is named “Equalisation tuning method”. The main advantage of this method is that it does not require any additional data from the operator except the measurement of the process steady-state change in an open-loop experi...

Pilot Aided Estimation and Equalisation of a Radio over Fibre System in WCDMA

In this paper the impact of a Radio over Fibre (RoF) subsystem on the capacity performance of Wideband Code Division Multiple Access (WCDMA) is evaluated. The study investigates the use of pilot aided channel estimation to compensate for the optical subsystem nonlinearities for different channel conditions, estimation intervals, and coding schemes. The results show that pilot aided channel esti...
