Junk Science? Four Arguments Against the Radiological Age Assessment of Unaccompanied Minors Seeking Asylum

Should radiological age assessment be considered as a means of alleviating thedoubts of a decision maker in the asylum procedure? The present article addressesthis question through a number of steps. First, it questions whether the use of radiologicalimaging methods in the age assessment of unaccompanied adolescents seekingasylum complies with the internal norms of the forensic science community.

Evaluating a GUI Development Tool for Internet of Things and Android

In the emerging field of Internet of Things (IoT), where computerized devices are combined in creative new ways, there is a need to create Graphical User Interfaces (GUIs) for the systems being built, e.g. in the form of Android “apps”. This is generally a complicated, time consuming task. We report from a controlled experiment that evaluates a new approach for building GUIs that aims to make it e

Attractive Patchy Protein Interactions : Understanding of protein dimerization

Protein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues. This results inmore or less anisotropic interactions depending on external parameters such assalt and pH. However, a deeper uProtein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues.

A brain potential signalling linguistic pre-activation? : an analysis of the pre-activation negativity (PrAN)

Introduction: It has previously been found that strongly predicted words can be pre-activated in constraining contexts (e.g. DeLong, Urbach & Kutas, 2005). Furthermore, it has been suggested that an anticipated continuation from one syllable to another can be pre-activated before it is present in the input (Roll, Söderström, Mannfolk, Shtyrov, Johansson, van Westen & Horne, 2015). We descr

Strategic entrepreneurship and knowledge spillovers: spatial and aspatial perspectives

The literature in the Strategic Entrepreneurship (SE) is increasingly embracingthe concept and implications of knowledge spillovers. In this paper, we add to thetheoretical repertoire on SE and knowledge spillovers by investigating the types ofknowledge spillovers and what they imply for various dimensions of SE. On the one hand,we distinguish between spatial and aspatial knowledge spillovers. On

In-between strengthened accessibility and economic demands : analysing self-service libraries from a user perspective

Purpose - The aim of this paper is to explore the implementation of self-service at public libraries from the perspective of their users. The implementation of self-service is related to a diverse societal context including for example an overall digitalisation, budget constraints and political expectations on public libraries to contribute to marketing the local community.Methodology - Semi-struc

Qualitative questionnaires as a method for information studies research

Introduction. We present qualitative questionnaires, originally an ethnological method for documenting and collecting material about everyday life, as a fruitful method for information studies. Method. Since the early 20th century qualitative questionnaires, on various themes, have been sent out to informants. The answers to qualitative questionnaires consist of memories, opinions and experiences.

Memory Power Management for Java Processors Using Heap Partitioning and Power Gating

Power consumption is an important design parameter for battery operated devices, and an especially sensitive issue in embedded Java systems. This paper presents a solution to reduce leakage power consumption of the heap memory characteristic of Java processors. By partitioning the heap into several memory banks and taking advantage of a compacting garbage collector, our method dynamically powers o

Code Generation for a SIMD Architecture with Custom Memory Organisation

Today’s multimedia and DSP applications impose requirements on performance and power consumption that only custom processor architectures with SIMD capabilities can satisfy. However, the specific features of such architectures, including vector operations and high-bandwidth complex memory organization, make them notoriously complicated and time consuming to program. In this paper we present an aut

Exploiting antenna correlation in measured massive MIMO channels

We investigate antenna correlation of an M-antenna massive multiple-input multiple-output (MIMO) setup with the purpose of obtaining a low-rank representation of the instantaneous massive MIMO channel. Low-rank representation bases using short-term and long-term antenna correlation statistics are defined, and their performance is evaluated with data sets obtained from channel measurements in both

Performance evaluation of CoMP transmission schemes using measurements versus the COST 2100 channel model

Coordinated Multi Point (CoMP) transmission and reception techniques are used in order to improve the performance of single or multiple cells in wireless systems. A system using CoMP techniques is capable of jointly optimizing its transmission and/or reception and, hence, achieving higher performance. In this work, performance evaluation of three CoMP techniques are performed based on simulations

Evaluation of the effect of base station antenna polarization on the performance of CoMP transmission techniques based on synchronous multi-link measurements

In this paper, the effect of polarization on the downlink sum-rate capacity of multi-user Cooperative Multi-Point (CoMP) systems using synchronous multi-link measurement data, for two different antenna arrangements, is studied. In the first setup, four antenna patches each of which with dual-polarized antenna elements at the base station (BS) with inter-patch distance varied from half wavelength tIn this paper, the effect of polarization on the downlink achievable sum-rate of multi-user Cooperative Multi-Point (CoMP) systems is studied using synchronous multi-link channel measurements with two different antenna arrangements. In the first setup, four dual-polarized antenna patches with inter-patch distance varied from half wavelength to 8 m are considered at the base station (BS). In the se

On The Coherence Time of Fiber-Based Distributed Antenna Systems

The possibility of using radio over fiber (RoF) analog transmissions to characterize the wireless propagation channel of distributed antenna systems is investigated. In particular, the coherence time of kilometer-long, fiber-based networks is analyzed. Joint measurements of the phase noise of parallel links to the same site (intra-site) and to different sites (inter-site) in such a network are pre
