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

FE-formulation of a nonlocal plasticity theory

A nonlocal continuum plasticity theory is presented. The nonlocal field introduced here is defined as a certain weighted average of the corresponding local field, taken over all the material points in the body. Hereby, a quantity with the dimension of length occurs as a material parameter. When this so-called internal length is equal to zero, the local classical plasticity theory is regained. In t

Streams of words: hydrological lexicon in Jahai

This article investigates hydrological lexicon in Jahai, a Mon-Khmer language of the Malay Peninsula. Setting out from an analysis of the structural and semantic properties as well as the indigenous vs. borrowed origin of lexicon related to drainage, it teases out a set of distinct lexical systems for reference to and description of hydrological features. These include (1) indigenous nominal label

Perceptions of socioeconomic integration of middle eastern immigrants in Europe : comparing national discourses and subjective experiences

This panel compares the subjective understanding of success and socioeconomic mobility of immigrants from the Middle East in Europe with national discourses of integration. Despite the abundance of research on Middle Eastern migrants in Europe, not much is known about their subjective understanding of their socioeconomic positions and experience with social mobility. Much of the research looks at

Distributed generation with voltage control capability in the low voltage network

Abstract in UndeterminedSmall-scale distributed generators connected tothe low voltage network are generally operated with unitypower factor. However, controlling their reactive powerinjection would have an impact on the voltage at theirconnection point, if the network is sufficiently weak andinductive. The purpose of this paper is to investigate how asmall-scale distributed generator connected to
