This paper discusses control of dissolved oxygen in a bioreactor when the stirrer speed is used as control signal. During batch and fed-batch cultivations the operating conditions change significantly which causes tuning problems, especially when performance requirements are high. A linearized process model reveals that the variations in the oxygen dynamics are mainly due to changes in the volumet

Computer control is entering all facets of life from home electronics to production of different products and material. Many of the computers are embedded and thus ``hidden'' for the user. In many situations it is not necessary to know anything about computer control or real-time systems to implement a simple controller. There are, however, many situations where the result will be much better when

George Scott (1804-74) kom 1830 till Stockholm som engelsk religionslärare, i praktiken metodistmissionär. Från 1831 predikade han på svenska och höll konventiklar, men först 1838 ledde detta till konflikt. Predikan vände sig mot predestination och fritänkeri. Ögonblicklig omvändelse och fullkomlig helgelse var dominerande motiv. Scott var verksam genom olika associationer, och talade ute i landet

In this project, we have explored RuO2 and Ru nanoparticles (∼ ∼10 and ∼ ∼5 nm, respectively, estimated from XRD data) to be used as gate material in field effect sensor devices. The particles were synthesized by wet chemical procedure. The capacitance versus voltage characteristics of the studied capacitance shifts to a lower voltage while exposed to reducing gases. The main objectives are to imp

2006 lades avhandlingen Safety culture in sea and Aviation transport fram vid Institutionen för Designvetenskaper vid Lunds tekniska högskola. Avhandlingsarbetet var framför allt en del av det LFV-finansierade HUFA-projektet (Human Factors in Air Navigation Services) vid Lunds universitet, samt en del av ett större sjösäkerhetsprojekt finansierat av bl.a. Sjöfartsverket och VINNOVA. Här följer en

Abstract in Undetermined This paper presents a new automatic algorithm for extracting properties of an individual artist’s style and applying those properties to other drawings. The algorithm can be used to ensure consistent artistic style across a project by automatically transferring a selected style to hand drawn images.

The study investigated the effect of positive and negative emotional valence (I.A.P.S pictures) on recollective experience, using the remember-know paradigm (Tulving, 1985), and confidence judgements. The negative valenced pictures were hypothesised elicit the recollective experience to a larger extent and to entail a higher degree of confidence in the correctness of memory responses than positive

Abstract in UndeterminedA more or less continuous process of structural change, not least due to a globalizing economy, poses a number of challenges to regions and local communities. However, when firms or whole industries are phasing out, windows of opportunity open up. Empirical analyses of two recent plant closures in Skane point at the importance of retaining existing knowledge bases, and at t
