Bedömning av examensmål i forskarutbildningen

Ett av underlagen till Lunds universitets utvecklingsprojekt EQ11 utgjordes av en undersökning av samspelet mellan examensmålen för forskarutbildningen och bedömningens utformning vid ett eller flera forskarutbildningsämnen från varje fakultet/område. Undersökningen utfördes under perioden februari-april 2011 och innebar att varje fakultetsledning utsåg de ämnen som skulle ingå. Redovisningen bygg

Guardians of the Past - Views on the Role of the Historian in Finland 1990 – 2000

In this seminar paper, I attempt an in-depth analysis of a collection of articles published in historical periodicals in Finland 1990-2000. My main interest concerns how the writers – mainly professional historians, representatives of scientific ideals of their age – discussed the idea of the Finnish nation during this decade, and how these discussions reflect a certain understanding of the work o

Floating Points of Reference. Trust, Enchantment and The Shifting Visibilities of Digital Infrastructures

In 2012 Google started a campaign to make parts of its infrastructure visible. Up until that year the company’s data centers had been highly secret facilities hidden from the public eye. The visualization campaign was mainly based on stories and images distributed via the Internet. The images were often suggestive, invoking both enchantment and trust. The text starts by pointing out and discussin

Regularization of the limiting optimal controller in robust stabilization

In this paper, we consider the problem of robust optimization for a system with uncertainty of rank one. The main result is the regularization of the limiting optimal controller. We will give the method to obtain the low order suboptimal controller that provides the stability margin as close to the optimal one as we wish. The method is illustrated by some scalar examples.

Interactivity and Spatiality - Experiences of Modelling Real Work Places as Virtual Places in a VR Collabortive Environment

In this paper I will discuss interactivity and spatiality, including the relationships between virtual places and work places. The paper reports some initial experiences of using a virtual reality (VR) tool for collaborative modelling. The aim was to investigate how well this technology could support participatory design of work environments. In a pilot study a group of researchers carried out an

Establishing Cause-Effect Relationships in Activated Sludge Plants - what Can Be Controlled

Plant wide control problems in the activated sludge process have been revisited. The ultimate criteria for controlling a complete plant have been systematically addressed only infrequently. In principle, the effluent has to meet the standard at a minimal cost. Basically, the process is at the time driven by disturbances, mostly via the influent flow, but sometimes created within the plant. An esse
