This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...

data envelopment analysis (dea) with considering the best condition for each decision making unit (dmu) assesses the relative efficiency for it and divides a homogenous group of dmus in to two categories: efficient and inefficient, but traditional dea models can not rank efficient dmus. although some models were introduced for ranking efficient dmus, franklin lio & hsuan peng (2008), proposed a...

We explore the use of the Spiral Array spatial visualization of tonal evolution through time for the visual analysis of P.D.Q. Bach’s The ShortTempered Clavier. In particular, we analyze situations in which we can see some of the humour devices abstracted in an earlier study by David Huron. We conclude that although we can see a good number of Schickele’s humour devices − such as incongruent st...

We demonstrate that deregulation in the form of vertical separation of network components into natural monopoly and potentially competitive markets does not truly represent a lessening of regulatory burdens. That is, vertical separation is not synonymous with deregulation; “more competitors” is not equivalent to “more competition”. We assume a public interest regulator that is constrained to se...

This paper extends the political agency approach to an environment in which voting may be divided between informed and instrumental, informed and ‘expressive’ and uninformed due to ‘rational irrationality’. It constructs a model where politicians may be good, bad or populist. Initially the existence of only good and populist politicians is assumed and the incentives for good politicians to pool...

Phosphorylation of the BH3 (Bcl-2 homology domain 3)-only protein BAD (Bcl-2/Bcl-X(L)-antagonist, causing cell death) can either directly disrupt its association with the pro-survival proteins Bcl-X(L) and/or Bcl-2, or cause association of BAD with 14-3-3 proteins. In the present study, we further characterize phosphorylation of BAD at Ser170, a unique site with unclear function. We provide fur...
