Wastewater treatment processes are inherently dynamic because of variations in the influent flow rate, concentration, and composition. The adaptive behaviour of the microorganisms further emphasizes this fact. Mathematical models and computer simulations are essential to describe, predict, and control the complicated interactions of the processes. Any attempt to model all details of the various re

n this paper a disturbance in the western part of the Swedish power system, 1997, January 1, is studied. Two large nuclear units tripped due to a short circuit in a substation. The purpose of this paper is to study the damping features of power oscillations by using synchronised measured frequency deviations between generators and the mean system frequency. The measurements are based on GPS (Globa

How might we understand the norms and normativity of international law? This is a conversation between international law and theology on the meaning of norms and normativity in international law - as seen from inside the discipline of international law.

In this egocentric article I describe briefly the segmental phonology of my own southern Swedish idiolect. I grew up in Getinge in central Halland, about 20 km north of Halmstad, speaking a regional variant of southern Standard Swedish. Although my dialect has certainly changed somewhat after I moved to Lund in 1964 at the age of 20, I believe that I still retain the basic pronunciation of vowels

The terms justice and peace have long been the focus of much debate as well as numerous attempts of conceptualization. Just peace however, has been very little studied despite being widely used together in everyday language. The terms justice and peace are therefore insufficiently conceptualized together and surprisingly little interest has been given to how a just peace can be realized. This pape

Most identification and design methods for discrete time data assume that the inputs and outputs are sampled at the same time instants. In practice, there is always a delay due to the conversion times in the analog to digital converters. In the paper it is shown how data with sampling delays can be used to obtain the model corresponding to synchronous sampling. The modification is simple and can b

New anti-inflammatory drugs with fewer adverse effects than existing drugs may prove to be useful in the treatment of several inflammatory disorders. A critical step in acute inflammation is the infiltration of neutrophils into tissues. Therefore, molecules that target and inhibit this early inflammatory event are attractive to engineer to suit medical needs. The Chemotaxis Inhibitory Protein of

Popular Abstract in Swedish Denna avhandling består av sex kapitel. Det första kapitlet är en introduktion medan de resterande fem innehåller avhandlingens huvudsakliga bidrag. De tre första kapitlen är samförfattade med Joakim Westerlund. Kapitel två har sin utgångspunkt i Westerlund (Empirical Economics 37:517-531, 2009) som visar på en svaghet i det populära LLC (Levin et al. Journal of EconomThis thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. Chapter 2 continues and extends the analysis in Westerlund (Empirical Economics 37:517–531, 2009), who demonstrates that the performance of the popula
