The problem to minimize power losses in an electrical network subject to voltage and power constraints is in general hard to solve. However, it has recently been discovered that semidefinite programming relaxations in many cases enable exact computation of the global optimum. Here we point out a fundamental reason for the successful relaxations, namely that the passive network components give rise

Today's power plants are shifting their combustion toward a more complex fuel mix on the grounds of environmental impact, cost, availability and regulations. Certain new types of fuel can be classified into the following groups: herbaceous material (straw and grass), agricultural by-products (pits, shells and hulls), wood, and waste fuels. These fuels contain various amounts of alkali metals, main

Chemical control of desert locust (DL) is carried out over large areas of land, covering a range of different landscapes and ecosystems. There are no real restrictions for spraying in or close to environmentally sensitive areas and awareness of sensitivity is not always obvious to the people involved in control. However, concern about environmental issues in connection with DL control is growing a

Many insects rely on vision to find food, to return to their nest and to carefully control their flight between these two locations. The amount of information available to support these tasks is, in part, dictated by the spatial resolution and contrast sensitivity of their visual systems. Here, we investigate the absolute limits of these visual properties for visually guided position and speed con

This paper outlines promising avenues for empirical research on quantified control in healthcare work. A review of key insights from accounting, organization studies, and the emergent sociology of quantification indicates that numbers are productive as well as deceptive and seductive, that they enable control but can be evaded, and that they typically have unintended effects. It remains to be furt

Linear Parameter Varying (LPV) models can be used to describe the vehicular lateral dynamic behavior of self-driving cars. They are particularly suitable for model-based control schemes such as model predictive control (MPC) applied to real-time trajectory tracking control, since they provide a proper trade-off between accuracy in different scenarios and reduced computation cost compared to nonlin

Äldreomsorgens komplexa verklighet behöver studeras med en mängd olika metoder och tillvägagångssätt, med fokus på strukturella, interpersonella och personliga aspekter och med hänsyn till perspektiven hos de som får vård och de som ger vård. Socialhögskolans äldregrupp har sitt ursprung i ”VoV-gruppen” (omsorgens vardag och villkor) som professor Rosmari Eliasson-Lappalainen startade 1993. Äldreg

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor te

Popular Abstract in English Plant diseases are directly associated with food security because they result in severe reduction of plant yield and thus they add to the scarcity of foods in the world, which can lead to negative repercussions on humankind. Late blight disease that severely hit Ireland in 1840s, which was caused by Phytophthora infestans and is mentioned in the historical records as th

Current post-carbon transition trajectories are primarily based on a belief in technical solutions wherein considerations of the citizens’ role in collective mobilisation and transformation are largely overlooked. To this end, the thesis seeks to understand how citizens can become active agents of change within transition efforts and how their political agency can be empowered accordingly. This, b

In this thesis a framework for real-time model predictive control has been developed for JModelica.org, which is an open-source platform for simulation and analysis of dynamical systems. Model predictive control (MPC) is an advanced optimizationbased control method that uses a model of the process being controlled to optimize control. The framework was tested on three different processes, real and

An important factor for a user of web sites on the Internet is the duration of time between the request of a web page until an answer has been returned. If this response time is too long, the user is likely to abandon the web site and search for other providers of the service. To avoid this loss of users, it is important for the web site operator to assure that users are treated sufficiently fast.
