Introduction to embodied communication: why communication needs the body
No full textWachsmuth I, Lenzen M, Knoblich G. Introduction to embodied communication: why communication needs the body. In: Lenzen M, Wachsmuth I, Knoblich G, eds. Embodied Communication in Humans and Machines. Oxford: Oxford University Press; 2008: 1-28.The aim of this book is to launch and explore a new integrated and interdisciplinary perspective, the Embodied Communication Perspective. The embodied communication perspective creates a new framework to reinterpret empirical findings in the cognitive and neurosciences, and to integrate findings from different research fields that have explored similar topics without much crosstalk between them. At the same time, the embodied communication perspective can serve as a guide for engineers who construct artificial agents and robots which should be able to interact with humans
Examining the Global Environmental Impact of Regional Consumption Activities - Part 2: Review of input-output models for the assessment of environmental impacts embodied in trade.
No full textThis paper offers a detailed review of recently described single- and multi-region input–output models used to assess environmental impacts of internationally traded goods and services. It is the second part of a two-part contribution. In Part 1 [Turner, K., Lenzen, M., Wiedmann, T. and Barrett, J. in press. Examining the Global Environmental Impact of Regional Consumption Activities — Part 1: A Technical Note on Combining Input–Output and Ecological Footprint Analysis; Ecological Economics.] we describe how to enumerate the resource and pollution content of inter-regional and inter-national trade flows with the aim to illustrate an ideal accounting and modelling framework for the estimation of Ecological Footprints.
A large number of such environment-economic models have been described but only in the last few years models have emerged that use a more sophisticated multi-region, multi-sector input–output framework. This has been made possible through improvements in data availability and quality as well as computability. We identify six major models that employ multi-sector, multi-region input–output analysis in order to calculate environmental impacts embodied in international trade. Results from the reviewed studies demonstrate that it is important to explicitly consider the production recipe, land and energy use as well as emissions in a multi-region, multi-sector and multi-directional trade model with global coverage and detailed sector disaggregation. Only then reliable figures for indicators of impacts embodied in trade, such as the Ecological Footprint, can be derived
Small Hazard-Free Transducers
No full textIkenmeyer et al. (JACM'19) proved an unconditional exponential separation
between the hazard-free complexity and (standard) circuit complexity of
explicit functions. This raises the question: which classes of functions permit
efficient hazard-free circuits?
In this work, we prove that circuit implementations of transducers with
small state space are such a class. A transducer is a finite state machine that
transcribes, symbol by symbol, an input string of length n into an output
string of length n. We present a construction that transforms any function
arising from a transducer into an efficient circuit of size O(n) computing
the hazard-free extension of the function.
More precisely, given a transducer with s states, receiving n input symbols
encoded by l bits, and computing n output symbols encoded by m bits,
the transducer has a hazard-free circuit of size
m*n*2^O(s+l) and depth O(s*log(n) + l); in particular, if s,
l, m are element of O(1), size and depth are asymptotically optimal.
In light of the strong hardness results by Ikenmeyer et al. (JACM'19), we
consider this a surprising result

Distributed algorithms for low stretch spanning trees
No full textGiven an undirected graph with integer edge lengths, we study the problem of approximating the distances in the graph by a spanning tree based on the notion of stretch. Our main contribution is a distributed algorithm in the CONGEST model of computation that constructs a random spanning tree with the guarantee that the expected stretch of every edge is O(log3 n), where n is the number of nodes in the graph. If the graph is unweighted, then this algorithm can be implemented to run in O(D) rounds, where D is the hop-diameter of the graph, thus being asymptotically optimal. In the weighted case, the run-time of our algorithm matches the currently best known bound for exact distance computations, i.e., Õ(min{√nD, √nD1/4 + n3/5 + D}). We stress that this is the first distributed construction of spanning trees leading to poly-logarithmic expected stretch with non-trivial running time

Potentials to decarbonize electricity consumption in Australia
No full textAs part of the Paris Agreement, Australia intends to reduce total carbon emissions by 26-28% by 2030 relative to 2005. This chapter assesses the potential contribution of the electricity sector towards Australia’s intended emission reductions. A carbon footprint assessment of different renewable energy options based on hybrid life cycle assessment is performed to estimate all economy-wide carbon emissions related to a changing energy mix in electricity generation. Results show that decarbonization efforts in the electricity sector alone are likely to be insufficient to reach Australia’s climate goals or to stay within the national carbon budget
