OTA Performance Evaluation of MIMO Terminals with Multipath Simulator

With the ever growing requirement for higher data rates, terminals supporting multiple-input multiple-output (MIMO) technologies (or MIMO terminals) are being developed for the beyond-3G wireless communication systems such as HSPA and LTE. To ensure that the terminals are capable of delivering the promises of MIMO technology, test systems for the performance evaluation of MIMO devices are needed.

Real-time sharing of gaze data between multiple eye trackers : evaluation, tools, and advice

Technological advancements in combination with significant reductions in price have made it practically feasible to run experiments with multiple eye trackers. This enables new types of experiments with simultaneous recordings of eye movement data from several participants, which is of interest for researchers in, e.g., social and educational psychology. The Lund University Humanities Laboratory r

“It feels like home, this is my Malmö” : Place, media location and fan experiences of The Bridge

This article focuses on fan experiences of place in the Scandinavian crime series The Bridge (Bron||Broen). It offers four in-depth portraits of fans representing different modes of engaging with geographies of the imagination based on participant observations and qualitative semi-structured interviews with 80 audience members conducted in Denmark, Sweden and the UK. The analysis draws attention t

Engaging with The Bridge : cultural citizenship, cross-border identities and audiences as ‘regionauts’

This article explores civic engagement with the Danish/Swedish crime series The Bridge (Danmarks Radio/Sveriges Television 2011–) based on qualitative interviews with 113 audience members, and drawing on the notion of cultural citizenship. The perspective of cultural citizenship, as understood and operationalized mainly by Hermes, is married with critical perspectives on the crime drama genre and

Sweden : Past Didactic Influence and Present Efforts to Create Learning Progressions

The Swedish school system comprises three school types: preschool, compulsory school (9 years) and secondary school (3 years). The latest curriculum reform was completed in 2011, updating policy documents and restructuring syllabuses, clarifying subject specific abilities and knowledge requirements. In 2012, national tests in geography were instituted for years 6 and 9, yielding support for equal

End-User Composition of Graphical User Interfaces for PalCom Systems

In ubiquitous computing, end-user composition allows users to combine multiple single-purpose devices into new, interesting constellations. In PalCom – a ubiquitous middleware – this is achieved without the need to write program code. In this paper we present a solution that in the same way allows users to create Graphical User Interfaces (GUIs) for such systems without coding. The approach is to

Day-to-Day Living Expenses and Mental Health

We use rich longitudinal survey and register data on Swedish individuals to examine the relationship between financial strain and mental health. Specifically, we consider the longitudinal relationships between payment difficulties and subjective (self-reported anxiety) as well as objective (psychiatric drug use) measures of mental ill-health. Among previously healthy individuals, payment difficult

Identity shifts and conflict transfromation - Probing the Israeli history debates

This article investigates into narratives of Israeli history and identity and ways in which those can be understood as linked to the transformation of intractable conflicts. By using the case of Israeli New History, this study elaborates on the interplay between master and counter commemorative narratives of identity and history, and the potential impact of that interaction when it comes to the de

Noise colour and the risk of population extinctions

A recurrent problem in ecology and conservation biology is to estimate the risk of population extinctions. Extinction probabilities are not only imperative for conservation and management, but may also elucidate basic mechanisms of the regulation of natural populations. The usual way of modelling stochastic influence on population dynamics has been to assume that the external noise is uncorrelated

Red, blue and green : Dyeing population dynamics

Numbers or densities of a natural population typically change over time. These fluctuations result from density-dependence mechanisms in the populations or external environmental variations. According to modern ecological research, time series describing population sizes and physical environments tend to be dominated by low-frequency fluctuations, whereas, contrary to this, simple population dynam

Flee or fight uncertainty : Plant strategies in relation to anticipated damage

In order to cope with damage, plants have evolved a number of strategies. We incorporate two of those strategies, compensatory regrowth and escaping damage in time, into a mathematical model in an attempt to outline under what circumstances one or the other of these phenotypic traits will evolve. Escaping damage in time is accomplished by flowering and setting seeds at a point of time when the ris

Experimental Uncertainties of the Heat Flux Method for Measuring Burning Velocities

The laminar burning velocity is a fundamental property of combustiblemixtures important for kinetic model validation as well as for practicalapplications. Many efforts are directed towards its accurate determination.The heat flux method is one of the commonly recognized methodsfor measuring laminar burning velocity, however, the information on theaccuracy of the method is scattered in the literatu

Art ventures as hybrid organisations: Tensions and conflicts relating to organisational identity

Research indicates that hybrid ventures face more complexchallenges than other ventures, due to multiple institutional logics. Institutionallogics theory suggests that this is due to different institutional backgrounds thatinfluence actor perspectives and expectations on decision making authority andventure identity, which in turn result in tensions and possible conflicts,especially over time. The

Robust time-of-arrival self calibration and indoor localization using Wi-Fi round-trip time measurements

The problem of estimating receiver-sender node positions from measured receiver-sender distances is a key issue in different applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using UWB and mapping and positioning using round-trip-time measurements between mobile phones and Wi-Fi-units. Thanks to recent research in this area we have an incre
