Holger Schrammgeneralized least squares model up to a few unknown parameters, say θ. θ.,..., θ.. This would occur, for example, when correlation in the errors of a time series regression model is suspected or when cross-sections of data are expected to satisfy a regression relationship with varying precisions.

Saskia Jaszoltowski,Albrecht Riethmüllerintroduction to science. An important part of the problem, it is argued, lies not so much in how we teach science, but in what we teach. It is argued that the principal outcomes of science education should be appropriate mental models of the phenomena of the various science domains. Intelligent tuto

In this paper the relative merits and drawbacks of these systems are critically reviewed, also with respect to the educational context in which they will have to be

Nicolas Ruthe categorized in different levels based on their difficulty levels (easy, normal, and hard) and calculation amounts (small, normal, and large). Additionally, the problems are ordered from the easiest problem with the smallest computations to the most difficult problems with the largest calculations.

Herbert Bruhnders current control techniques for single- and three-phase voltage-source converters which are connected to a generalized load as introduced in the previous chapter. The two techniques in question are referred to as hysteresis and model based current control. The use of this type of load is instruc
