In this paper, we suggest methods for the adaptive assessment and training of students. The main idea is to apply the theoretical concept of the neighbourhood of a knowledge state to adaptive training. We also describe improvements of existing assessment algorithms. These ideas are implemented in a multi–platform tutoring system shell. This shell has been applied to two different fields of know...

In the last years the integration of operation calls in the context of dynamic, personalized interfaces has become a ’must’ for Web Applications. However, existing conceptual modeling proposals have just tangentially tackled the conceptual definition of its corresponding operation interfaces, which many times involve concepts far more complex than those related to text field input. This paper p...

Two-state cooperativity is an important characteristic in protein folding. It is defined by a depletion of states that lie energetically between folded and unfolded conformations. There are different ways to test for two-state cooperativity; however, most of these approaches probe indirect proxies of this depletion. Generalized-ensemble computer simulations allow us to unambiguously identify th...

In the previous chapters a variety of formal models of the teaching-learning process have been presented. With one major exception, however, all of the models have a largely stochastic foundation. The structural learning theory (SCANDURA, 1973a, forthcoming, also this volume) is based (partly) on the assumption that deterministic theorizing about teaching and learning might actually provide a m...

The determination of the phylogenetic relationships among microorganisms has long relied primarily on gene sequence information. Given that prokaryotic organisms often lack morphological characteristics amenable to phylogenetic analysis, prokaryotic phylogenies, in particular, are often based on sequence data. In this work, we explore a new source of phylogenetic information, the distribution o...

Fault rocks from the classic Rocky Mountain foreland fold-and-thrust belt in southwestern Canada were dated by Ar analysis of clay grain-size fractions. Using X-ray diffraction quantification of the detrital and authigenic component of each fraction, these determinations give ages for individual faults in the area (illite age analysis). The resulting ages cluster around 72 and 52 Ma (here calle...

Rotella, F., Shuffle product of generating series, Theoretical Computer Science 79 ( 1991) 257-261. In this note, we give a short proof of the explicit and recurrent construction of the shuffle product of two noncommutative formal power serIfis This construction is simply expressed in terms of linear matrix algebra.

Spencer, J., Ulam’s searching game with a fixed number of lies, Theoretical Computer Science 95 (1992) 3077321. Paul tries to find an unknown x from 1 to n by asking 4 Yes-No questions. In response Carole may lie up to k times. For k fixed and n, 4 sufficiently large, necessary and sufficient conditions are given for Paul to win.

Prospects for future measurements of Deeply Virtual Compton Scattering at HERMES are studied using different simple models for parameterizations of generalized parton distributions (GPDs). Measurements of the lepton charge and lepton beam helicity asymmetry will yield important input for theoretical models towards the future extraction of GPDs.
