In this paper, an automatic method for reducing chemical mechanisms during run time based on the quasi-steady-state assumption (ASSA) is presented. The method uses a lifetime analysis of the chemical species which can be set to steady state according to a ranking procedure. Steady-state species concentrations are computed by algebraic rather than differential equations, thus yielding a significant

Evaluation of IT investments is a difficult and complicated issue. This chapter presents a framework for control of IT investments with the aim of providing decision-makers with a clear picture of individual IT investments as well as an aggregated level where all IT investments are combined into a total picture. The framework has been developed using an action–research approach.In a number of work

I am grateful to Daniel Little for his insightful reply to my recent article in Social Epistemology (2012, 105-114) about what appears to be a flaw in Jon Elster’s conception of mechanisms. I agree with much of what Little says, but want to amplify a different underlying problem with Elster’s conception (fourth point below) than Little suggests in his reply (third point below). This underlying pro

This paper presents a study of the main advantages of inverted decoupling in 2×2 processes. Two simulation examples and an experimental process are used to show these advantages in comparison with simplified decoupling. The study focuses on the following practical advantages: the apparent process is the same as that obtained if one loop changes to manual; bumpless transfer and anti-windup are achi

The described technical-economic model clarifies the influence of different production technological factors on the processing cost of a part. The model represents the fundamental theory for the judging of different types of production development. Various influential factors can be weighted against each other, which leads to different production development scenarios and their effects on the proc

Den högskolepedagogiska utvecklingsplanen har utvecklats i samband med en högskolepedagogisk fortsättningskurs på HT-området höstterminen 2006. Utvecklingsplanen applicerades på kursen "Utomeuropeisk musik" (7,5 p) som var en delkurs i en grundläggande 30p-kurs för alla nybörjare på A-nivå inom musikvetenskapen vid Lunds universitet.

Popular Abstract in Swedish Den engelska medeltidsdikten Pearl studeras främst mot bakgrund av Pseudo-Dionysius tankar samt den samtida kontemplativa litteraturen (d v s Julian of Norwich, Margery Kempe, Walter Hilton, Richard Rolle och den okände författaren av The Cloud of Unknowing). Det är framförallt med avseende på medeltida teologiska frågor om människans möjlighet och begränsing att förståThis dissertation places Pearl in the context of works by the English fourteenth-century contemplative writers (‘mystics’), as well as of patristic and other theological treatises, focusing on the theme of comprehending and speaking about a transcendent divine dimension. The purpose is to show that Pearl and the works of Julian of Norwich, Margery Kempe, Walter Hilton, Richard Rolle and the author
