In many applications where speech separation and enhancement is of interest, e.g. conferencing systems, mobile phones and hearing aids, accurate speaker localization is important. This paper presents an alternative criteria for the well known steered response power with phase transform (SRP-PHAT) algorithm, in which the steered response relates to peaks in the fourth order cross cumulant, rather t

We present a variational formulation of the governing equations and introduce global indicators to describe the behavior of acoustofluidic devices driven at resonance frequencies by means of a piezoelectric transducer. The individuation of the correct Lagrangian densities for the different parts constituting the device (the piezo transducer, the silicon walls, the fluid-filled microchannel, and th

Nation branding has been criticised for leading to the homogenisation and depoliticisation of national interest and identity. This study examines the politics of nation branding in relation to its configuration with public diplomacy and the institutional policy context in which they are embedded. Informed by Scandinavian institutionalism and the analytical concept of translation, the study reveals

This article takes a sceptical view of the functionalist understanding of the nature and significance of ‘knowledge’ in so-called knowledge- intensive companies. The article emphasizes the slipperiness of the concept of knowledge, the ambiguity of knowledge, its role in what is constructed as knowledge work and the evaluation of work outcomes. Given this ambiguity, the management of rhetoric, imag

“Across all borders”: An investigation into media activities and the Scandinavian Media Model in 1959In this case study we are going to investigate two different radio productions that in interesting ways were crossing the geographical borders between the countries Sweden and Norway and between Sweden and Denmark in the year of 1959. Through the concepts of border (see Hurd et al. 2006) showing ho

Despite having been subject to a strong and many-sided critique, instrumental rationality persists as paramount in transport planning practice and research. This paper argues that it is crucial to acknowledge the prescriptive and normative facet of instrumental rationality in order to understand its impact on transport planning. The aim is to explore to what extent pedestrian planning – within a s

Poly(arylene ether sulfone)s containing randomly distributed biphenyl units tethered with precisely six imidazolium cations are designed and prepared with the aim to facilitate ionic clustering and conductivity of anion exchange membranes (AEMs). A series of statistical copolymers with different cationic contents are synthesized via K2CO3-mediated polycondensations of 2,2′,3,3′,5,5′-hexamethyl-4,4

Tonsättaren, radiomedarbetaren och musikern Hans Holewa (1905–1991) anlände till Sverige 1937 som landsflyktig undan den tilltagande antisemitismen i Wien, drygt ett halvår innan Österrike annekterades av Nazityskland. Som invandrad radikal tonsättare med den så kallade tolvtonstekniken som utgångspunkt, med judiskt påbrå och med engagemang inom vänsterrörelsen kom Holewas svenska exiltillvaro utg

Although genotype-by-environment interaction has long been used to unveil the genetic variation that affects Darwinian fitness, the mechanisms underlying the interaction usually remain unknown. Genetic variation at the dimeric glycolytic enzyme phosphoglucoisomerase (Pgi) has been observed to interact with temperature to explain the variation in the individual performance of the butterfly Melitaea

Background: Copeptin is a reliable surrogate marker for the neurohypophyseal hormone vasopressin. Elevated plasma level of copeptin has been associated with cardiovascular and metabolic disease risk. Objective: To investigate the association between copeptin and risk of dementia. Methods: In all, 18,240 individuals from Malmö, Sweden, were examined between 2002 and 2006 (mean age 69.3 years, 69.8

This essay examines Byron's and Shelley's reactions to, and involvement with, the Neapolitan Revolution of 1820–21, using them to focus a debate about conflicting constructions of history in their writing, and to question subsequently conventional accounts of their creative relationship. It concentrates on Shelley's Ode to Naples, which it identifies as in important rhetorical blow in Shelley's pu

There is a strong general concern amongst policymakers worldwide that multinational enterprises engage in far-reaching tax-planning activities. It is generally thought that by using transfer pricing or other techniques to shift profits, multinational enterprises can avoid taxation and thereby erode tax bases. Several attempts have been made to tackle this problem, not least through the OECD/G20 in

A model for calculating the noise in nonlinear optical processes arising from (nonquantum) stochastic fluctuations (mode beating) in and between the lasers participating in the nonlinear interaction has been previously developed. Assuming that all individual laser mode phases and laser modes are (statistically) independent (Gaussian statistics) and that the nonlinear interaction can be expressed a

Pure rotational coherent anti-Stokes Raman scattering (CARS) has for the first time been investigated for pressures up to 44 MPa in nitrogen gas at room temperature. An atomic filter consisting of a heated cell with sodium vapour was successfully applied for suppression of stray light originating from the narrowband CARS pump laser beam. With increasing pressure the rotational CARS spectrum is smo
