Murine type C endogenous virus expression in murine 129 teratocarcinoma cell line]

Murine type C viral information is detectable in the cellular genome of both differentiated and undifferentiated cell lines derived from 129 Mouse teratocarcinoma. Cytoplasmic RNA expression which is negligible in differentiated cells, is significantly higher in multipotential undifferentiated cells. Furthermore it was observed that in vitro differentiation of multipotent cells leads to a decrease of this expression.     

General systems: A basis for knowledge engineering

General systems formalizations of expert knowledge play a foundational role in the process of knowledge engineering of intelligent systems. Canonical definitions of systems (knowledge structures) which have been arrived at by a crossdisciplinary inductive modeling process are shown to be the basis for the modeling of certain generic categories of expert reasoning processes which are of current interest in knowledge engineering. The methodology for transforming the representation of knowledge expressed in general systems formalizations to the representation of that knowledge in expert systems is also developed. In particular, transformations from general systems formalizations into frames are presented.     

Modelling peak electricity demand

This paper estimates a forecasting equation for the hourly peak electricity demand one day in the future. The models incorporate deterministic influences such as holidays, stochastic influences such as average loads by building bivariate models, and exogenous influences such as the weather which is given a careful non-linear formulation. Out-of-sample comparisons are made using an additional year of data.
