Cities and climate change: The great decarbonisation challenge

We are in the midst of “the critical decade”. It is now that our decisions and actions in relation to mitigation of and adaptation to climate change will determine the success or failure of decarbonisation transitions needed to avoid severe impacts of climate change. This is not solely a technological, social, economic or governance issue. Addressing climate change demands fundamentally different

Optimal Linear Control for Channels with Signal-to-Noise Ratio Constraints

We consider the problem of stabilizing and minimizing the disturbance response of a SISO LTI plant, subject to a stochastic disturbance, over an analog communication channel with additive white noise and a signal-to-noise ratio (SNR) constraint. The controller is linear, based on output feedback and has a structure with two degrees of freedom: One part represents sensing and encoding operations an

Polarization corrections to core levels

Theoretical predictions for ionization energies of inner core electrons generally come out much more accurately by taking the difference between the total energies of two self-consistent Hartree-Fock calculations than by using Koopmans' theorem. For the outer core electrons, on the other hand, little or no improvement over Koopmans' theorem is obtained from a `ΔSCF method'. We show here that the

Evaluation of the Telia scattered field measurement method for estimation of in-network performance of mobile terminal antennas

In this paper we present and evaluate a method for estimation of in-network performance of mobile terminal antennas developed by the Swedish telecom operator Telia. The Telia Scattered Field Measurement (TSFM) Method is intended to give a better estimate of the performance of the mobile terminal antenna as in an in-network fading scenario. The parameter measured from the TSFM method is referred t

Theory and Reality : Metaphysics as Second Science

Popular Abstract in Swedish "Theory and Reality" handlar om vilka slutsatser vi kan dra om världen från de vetenskapliga teorier vi har. I allmänhet är dessa svåra att tolka bokstavligt, och de används ofta just som redskap, snarare än som beskrivningar av verkligheten. Men för att vara användbara redskap måste teorier ha vissa kopplingar till vad de handlar om. Theory and Reality beskriver sådaTheory and Reality is about the connection between true theories and the world. A mathematical framefork for such connections is given, and it is shown how that framework can be used to infer facts about the structure of reality from facts about the structure of true theories, The book starts with an overview of various approaches to metaphysics. Beginning with Quine's programmatic "On what there

Sustainable businesses practices in supply chains: learning from Swedish companies

Businesses play a vital role in building a more sustainable society by practicing and promoting more socially and environmentally responsible practices along supply chains. The social and environmental conduct of Western companies in their respective countries is usually rather strong due to the existing strong legislation on human rights, working conditions, freedom of trade unions, etc. In devel
