Modeling spike and drops dependence in european electricity markets

Electricity and gas prices are characterized by sharp increases or decreases in their price, followed a few days later by an equally large decreases or increases. These phenomena are called spikes or drops and are causing headaches for system developers and planners. One of the explanations for the spikes are sudden increases in demand (eg cold weather) and/or decreases in supply (eg emergency shu

Har EU en balanserad konkurrensprocess, som uppfyller fundamentala rättsäkerhetskrav?

• EUs konkurrensrättsliga påföljder är att betrakta som straffrättsliga. – Tilltron till myndigheters agerande förhindrar en pseudostraffrättslig process; – Det är orimligt att skapa ett administrativt/straffrättsligt ”light” förfarande; – Separation av makt mellan organ och krav på att sanktionssystem är legala. • Artikel 6 i Europakonventionen förutsätter en full och balanserad prövning av tek

Detection and Diagnosis of Oscillation in Control Loops

Previous work presented a real-time algorithm for detection of oscillations in PI and PID feedback control loops. This paper examines further opportunities for oscillation detection in the off-line analysis of ensembles of data from control loops. Its use with measurements from routine operations is emphasised. The paper presents operational signatures that indicate the cause of an oscillation. Ty

THE COMMUNICATION HAVE-NOTS—Understanding communication control and “counter-publics” in contemporary China

This paper takes a new perspective on power and dominance in contemporary China by focusing on the Party-state’s control over communication. By looking at “counter-publics,” the voiceless in the Chinese public sphere, this paper investigates how the Party-state strengthens its controls over freedom of expression; deprives people of means of expression, interaction, and communication; and excludes

Probing Proton Translocation in Influenza A/M2 Proteoliposomes - A systematic Approach to Membrane-Protein Reconstitutions

Popular Abstract in Swedish Allt levande består av celler. Cellen är livets allra minsta byggsten. Cellen har ett hölje som kallas cellmembran. Detta membran skiljer cellens inre som kallas cytosol från omvärlden. I detta cellmembran sitter olika protein inbäddade. Genom dessa protein kommunicerar och utbyter cellen ämnen med sin omgivning. Många av dessa protein är mål för läkemedel och är därförAn improved method for reconstituting membrane proteins into artificial liposomes for quantitative functional analysis is presented. A number of key parameters for reconstitution by detergent removal are assessed in this thesis: The lipid-to-protein ratio, the detergent-to-lipid ratio and the lipid and cholesterol composition. New porphyrin-based pH-probes are evaluated. Based on this systematic,
