Research on Wearable, Immersive Augmented Reality (WIAR) Adoption in Maritime Navigation
Authors: Grabowski Martha
Published: January 2015

Understanding the impact of technology introduction on users’ attitudes toward and behaviour with technology is increasingly important. This paper suggests several research questions that are important as Wearable, Immersive Augmented Reality (WIAR) systems are introduced in ship navigation: what contributions to navigation decision-making might be made by WIAR technology? And how do these influences relate to safety in marine transportation? This paper begins with an overview of information needs for shipboard navigation and piloting, and then describes the evolution of shipboard decision support systems for navigation, including the emergence of wearable, immersive augmented reality systems. An assessment of piloting and navigation information needs and the capabilities of WIAR are then presented, which suggests a conceptual model for studying the impact of WIAR systems on performance and safety in marine transportation. Conclusions and future work to explore the role and contribution of WIAR technology to the safety of navigation are then presented.
Research of Vessel Traffic Safety in Ship Routeing Precautionary Areas Based on Navigational Traffic Conflict Technique
Authors: Li Song , Zhou Jianghua , Zhang Yuanqiang
Published: January 2015

Recently, a basic pattern of coast seaway system networking has been established in China. As a result, a large number of precautionary areas will be gradually established. Because of the high frequency of ships' encounters and accidents, these precautionary areas have been a weak but important facet of ships' routeing. Navigational Traffic Conflict Technique (NTCT) was introduced to quantitatively evaluate the safety of precautionary areas. Focusing on traffic conflict, the calculation method of navigational traffic conflict points is discussed, and a comparison analysis of the two editions (2002 and 2008) of Yangtze estuary ships’ routeing is performed. Then the automatic acquisition system of navigational traffic conflict data that can be used in the quantitative analysis of the influence degree of a single traffic flow on the whole precautionary area safety is developed, and the left-turning traffic flows of Yangtze estuary ships’ routeing precautionary areas B are taken as an example. This article establishes a foundation for the precautionary area safety analysis system, and provides the decision basis for policy making in optimisation of geometric design and traffic organisation of precautionary areas.
The Return of the New Woman and Other Subjects of Weimar Gender History
Authors: LYBECK MARTI
Published: January 2015

After a drought of more than a decade, a substantial group of recent works has begun revisiting Weimar gender history. The fields of Weimar and Nazi gender history have been closely linked since the field was defined thirty years ago by the appearance of the anthologyWhen Biology Became Destiny: Women in Weimar and Nazi Germany. Following a flurry of pioneering work in the 1980s and early 1990s, few new monographs were dedicated to investigating the questions posed in that formative moment of gender history. Kathleen Canning, the current main commentator on Weimar gender historiography, in an essay first published shortly before the works under review, found that up to that point the ‘gender scholarship on the high-stakes histories of Weimar and Nazi Germany has not fundamentally challenged categories or temporalities’. Weimar gender, meanwhile, has been intensively analysed in the fields of cultural, film, and literary studies. The six books discussed in this essay reverse these trends, picking up on the central question of how gender contributed to the end of the Weimar Republic and the rise to power of National Socialism. In addition, four of the books concentrate solely on reconstructing the dynamics of gender relations during the Weimar period itself in their discussions of prostitution, abortion and representations of femininity and masculinity. Is emerging gender scholarship now shaping larger questions of German early twentieth-century history? How are new scholars revising our view of the role of gender in this tumultuous time?
Putting the economy back in to the city
Authors: RODGER RICHARD
Published: January 2015

Given the dominance of economic matters in the daily news, this article speculates why the topic has attracted relatively little attention amongst urban historians over the last 40 years, and why it is important that the local economy gains a wider acceptance as a powerful determinant of a city's fortunes.
Periodic Artifact Reduction in Fourier Transforms of Full Field Atomic Resolution Images
Authors: Hovden Robert , Jiang Yi , Xin Huolin L. , Kourkoutis Lena F.
Published: January 2015

The discrete Fourier transform is among the most routine tools used in high-resolution scanning/transmission electron microscopy (S/TEM). However, when calculating a Fourier transform, periodic boundary conditions are imposed and sharp discontinuities between the edges of an image cause a cross patterned artifact along the reciprocal space axes. This artifact can interfere with the analysis of reciprocal lattice peaks of an atomic resolution image. Here we demonstrate that the recently developed Periodic Plus Smooth Decomposition technique provides a simple, efficient method for reliable removal of artifacts caused by edge discontinuities. In this method, edge artifacts are reduced by subtracting a smooth background that solves Poisson’s equation with boundary conditions set by the image’s edges. Unlike the traditional windowed Fourier transforms, Periodic Plus Smooth Decomposition maintains sharp reciprocal lattice peaks from the image’s entire field of view.
A CONVOLUTION-INDUCED TOPOLOGY ON THE ORLICZ SPACE OF A LOCALLY COMPACT GROUP
Authors: AKBARBAGLU IBRAHIM , MAGHSOUDI SAEID
Published: January 2015

Let$G$be a locally compact group with a fixed left Haar measure. In this paper, given a strictly positive Young function${\rm\Phi}$, we consider$L^{{\rm\Phi}}(G)$as a Banach left$L^{1}(G)$-module. Then we equip$L^{{\rm\Phi}}(G)$with the strict topology induced by$L^{1}(G)$in the sense of Sentilles and Taylor. Some properties of this locally convex topology and a comparison with weak$^{\ast }$, bounded weak$^{\ast }$and norm topologies are presented.
Diverse mechanisms for spliceosome-mediated 3′ end processing of telomerase RNA
Authors: Kannan Ram , Helston Rachel M. , Dannebaum Richard O. , Baumann Peter
Published: January 2015

The 3′ end of Schizosaccharomyces pombe telomerase RNA (SpTER1) is generated by spliceosomal cleavage, a reaction that corresponds to the first step of splicing. The observation that the spliceosome functions in 3′ end processing raised questions about the evolutionary origin and conservation of this mechanism. We now present data in support of spliceosomes generating 3′ ends of telomerase RNAs in other fungi. Strikingly, the mechanistic basis for restricting spliceosomal splicing to the first transesterification reaction differs substantially among species. Unlike S. pombe, two other fission yeasts rely on hyperstabilization of the U6 snRNA—5′ splice site interaction to impede the 2nd step of splicing. In contrast, a non-canonical 5′ splice site blocks the second transesterification reaction in Aspergillus species. These results demonstrate a conserved role for spliceosomes functioning in 3′ end processing. Divergent mechanisms of uncoupling the two steps of splicing argue for multiple origins of this pathway.
A multi-subject, multi-modal human neuroimaging dataset
Authors: Wakeman Daniel G , Henson Richard N
Published: January 2015

We describe data acquired with multiple functional and structural neuroimaging modalities on the same nineteen healthy volunteers. The functional data include Electroencephalography (EEG), Magnetoencephalography (MEG) and functional Magnetic Resonance Imaging (fMRI) data, recorded while the volunteers performed multiple runs of hundreds of trials of a simple perceptual task on pictures of familiar, unfamiliar and scrambled faces during two visits to the laboratory. The structural data include T1-weighted MPRAGE, Multi-Echo FLASH and Diffusion-weighted MR sequences. Though only from a small sample of volunteers, these data can be used to develop methods for integrating multiple modalities from multiple runs on multiple participants, with the aim of increasing the spatial and temporal resolution above that of any one modality alone. They can also be used to integrate measures of functional and structural connectivity, and as a benchmark dataset to compare results across the many neuroimaging analysis packages. The data are freely available from https://openfmri.org/.
Direct growth of GaN layer on carbon nanotube-graphene hybrid structure and its application for light emitting diodes
Authors: Seo Tae Hoon , Park Ah Hyun , Park Sungchan , Kim Yong Hwan , Lee Gun Hee , Kim Myung Jong , Jeong Mun Seok , Lee Young Hee , Hahn Yoon-Bong , Suh Eun-Kyung
Published: January 2015

We report the growth of high-quality GaN layer on single-walled carbon nanotubes (SWCNTs) and graphene hybrid structure (CGH) as intermediate layer between GaN and sapphire substrate by metal-organic chemical vapor deposition (MOCVD) and fabrication of light emitting diodes (LEDs) using them. The SWCNTs on graphene act as nucleation seeds, resulting in the formation of kink bonds along SWCNTs with the basal plane of the substrate. In the x-ray diffraction, Raman and photoluminescence spectra, high crystalline quality of GaN layer grown on CGH/sapphire was observed due to the reduced threading dislocation and efficient relaxation of residual compressive strain caused by lateral overgrowth process. When applied to the LED structure, the current-voltage characteristics and electroluminescence (EL) performance exhibit that blue LEDs fabricated on CGH/sapphire well-operate at high injection currents and uniformly emit over the whole emission area. We expect that CGH can be applied for the epitaxial growth of GaN on various substrates such as Si and MgO, which can be a great advantage in electrical and thermal properties of optical devices fabricated on them.
Probing time-dependent mechanical behaviors of catch bonds based on two-state models
Authors: Chen Xiaofeng , Mao Zhixiu , Chen Bin
Published: January 2015

With lifetime counter-intuitively being prolonged under forces, catch bonds can play critical roles in various sub-cellular processes. By adopting different “catching” strategies within the framework of two-state models, we construct two types of catch bonds that have a similar force-lifetime profile upon a constant force-clamp load. However, when a single catch bond of either type is subjected to varied forces, we find that they can behave very differently in both force history dependence and bond strength. We further find that a cluster of catch bonds of either type generally becomes unstable when subjected to a periodically oscillating force, which is consistent with experimental results. These results provide important insights into versatile time-dependent mechanical behaviors of catch bonds. We suggest that it is necessary to further differentiate those bonds that are all phenomenologically referred to as “Catch bonds”.

Phasor measurement unit placement framework for enhanced wide‐area situational awareness
Authors: Sodhi Ranjana , Sharieff Md Imran
Published: January 2015

The wide‐area situational awareness (SA) aims at an early detection of impending system instability and to alert system operator to take necessary actions. Since a critical situation may be triggered in a system because of various reasons, a wide‐area monitoring system needs to consider several practical factors while deploying phasor measurement units (PMUs) in the grid. This study proposes a systematic framework for analysing the suitability of limited candidate PMU locations with respect to multiple applications, which, in turn, would enhance the SA of the system operator. Five factors are chosen for assessing the potential of a PMU site viz., improving state estimation, assessing voltage, angular stability, monitoring tie‐line oscillations and the availability of communication infrastructure. To quantify the contribution of each application in enhancing the SA, five respective factors are proposed. These five factors are finally integrated in the proposed framework using fuzzy technique for order of preference by similarity to ideal solution. The scope of this work, however, is not limited only to these five factors. PMU locations can be evaluated for any number of practical criteria. The proposed scheme is demonstrated on IEEE 14‐bus system and Northern Regional Power Grid 246‐bus Indian system. The proposed methodology enhances the SA by ranking and recognising the potential PMU locations, and placing them in a phased manner.

Authors: Ferreira David , Caldeirinha Rafael F.S. , Leonor Nuno
Published: January 2015

A channel sounder based on the cross‐correlation properties of pseudo‐noise random sequences, known as swept time delayed cross‐correlation channel sounder, is presented. This sounder enables the characterisation of doubly selective channels, providing both amplitude and Doppler spectra information. It performs real‐time measurements of specific radio channels with a high resolution of 2 ns for adjacent multipath component, and a current maximum Doppler spread of ±100 Hz, but that can go beyond ±1 kHz, if some components are upgraded. The amplitude measurements given by the sounder, presented as power delay profiles, have a dynamic range of about 35–40 dB. This study provides detailed information on the most relevant components used to develop the sounder, and presents some of the calibration measurements performed on the bench, as well as specific radio frequency measurements at 18.7 and 60 GHz in a controlled environment. Finally, improvements that are feasible to be implemented in the near future are proposed.
Characterisation of antenna substrate properties using surrogate‐based optimisation
Authors: Nguyen Phuong Minh , Chung Jae‐Young
Published: January 2015

In the current study, the authors present a technique to characterise the permittivity and loss tangent of an antenna substrate. In this method, an error function is formulated with measured data and a set of simulation data on the antenna's impedance and bandwidth. Subsequently, a surrogate‐based optimisation code is used to intelligently search for the substrate parameters that minimise the error function. The validity of the method is demonstrated by experiments on wearable patch antennas with felt substrates. The results show that the method is effective in retrieving the permittivity and loss tangent of the antenna substrate using the antenna itself as the test fixture. Thus, there is no need to prepare additional resonators or transmission‐line fixtures as in conventional substrate characterisation methods.
Water‐loaded metal diagonal horn applicator for hyperthermia
Authors: Singh Soni , Singh Surya Pal
Published: January 2015

This study presents the design of water‐loaded metal diagonal horn antenna at 2450 MHz along with simulation and experimental studies of specific absorption rate (SAR) and temperature distributions in a bio‐medium (muscle) in direct contact with the water‐loaded antenna for hyperthermia application. The metal diagonal horn is a multimode horn antenna, with identical aperture field distribution in the E‐ and H‐planes. The SAR distribution in a phantom muscle in direct contact with water‐loaded horn antenna measured at 2450 MHz is nearly in agreement with the corresponding simulated distribution. The simulation results for SAR distribution owing to diagonal horn are also compared with those owing to square aperture horn/box horn, of same aperture cross‐section/broader dimension as the diagonal horn at 2450 MHz. The results indicate that the diagonal horn provides higher penetration depth/better transverse resolution over square aperture horn/box horn. In addition, the proposed diagonal horn provides circularly symmetric effective field size. Finally, thermal simulation results are also provided for the proposed applicator, which is in direct contact with a realistic model of muscle medium without and with small spherical as well as oval‐shaped tumours of different dielectric properties embedded within the muscle medium.
Improved three‐phase, five‐level pulse‐width modulation switched voltage source inverter
Authors: Odeh Charles I.
Published: January 2015

This study presents an improved three‐phase, five‐level pulse‐width modulation (PWM) switched voltage source inverter. The single‐carrier, multilevel PWM scheme is employed to generate the gating signals for the power switches. Operational principles with switching functions are given. By controlling the amplitude modulation index, three‐ and five‐level output phase voltage waveforms can be achieved. For modulation indices of 0.45, and 0.9, the proposed inverter topology was subjected to an R–L load and the respective number of output voltage level were synthesised. For a step change in the modulation index, the response of the proposed multilevel inverter circuit topology is demonstrated. Fast Fourier transform analyses of the output line voltage waveforms, at the indicated depth of modulation, were carried out and the corresponding total harmonic distortion values were obtained. Comparison of the proposed inverter configuration and the classical 3‐ϕ topologies is given based on the power circuit component count. Moreover, analysis of the conduction power losses in the power semiconductor switches of the proposed inverter topology is given. To verify the performance of the proposed inverter architecture, simulations and experiments are carried out on a 3.46 kW rated prototype of the proposed inverter for an R–L load; and adequate results are presented.

Published: January 2015

Rice kernel (RK)‐like bismuth telluride (Bi2Te3) crystals were successfully synthesised by microwave‐induced plasma heating of Bi and Te powders. Phase and morphology characterisation revealed the presence of the Bi2Te3 structure in the shape of RKs. The crystal orientation factor (f value) of RK Bi2Te3 powder was larger than that of the RK Bi2Te3 hot‐pressed disk. A comparison of the f values of both samples suggested that the RK shape has significant influence in reducing the f value after hot processing. The Seebeck coefficient (S), electrical resistivity (ρ) and thermal conductivity (κ) of the RK Bi2Te3 disk were determined over the temperature ranging from 323 to 623 K. The S value was negative over the whole temperature range, indicating an n ‐type thermoelectric RK Bi2Te3 disk. The power factor (S2ρ−1) was the highest at about 1.07 × 10−3W/m K2 at 323 K and decreased with increasing temperature. The maximum dimensionless figure of merit (ZT) of the RK Bi2Te3 disk was 0.26 at about 366 K.
Public Services Performance: An Extended Framework and Empirical Assessment across the Enlarged EU

Published: January 2015

Performance of the public sector is at the core of long-term wealth creation and welfare improvement. Yet, its measurement remains inadequate and flawed with data deficiency. In this paper we propose an extended framework for the assessment of public services performance that accounts for long-term impacts on welfare and empirically evaluate it across twenty-five European countries on the basis of a wide set of proxy indicators. We relate the performance scores to input costs indices and propose a coherent typology of countries that corresponds to the patterns of economic effectiveness of public services. The empirical analysis reveals that, because of differences in input costs across the enlarged EU, the economic effectiveness of public services varies to a much larger extent than the performance, with some relatively large-sized governments (Sweden, Denmark, Austria) being the most effective ones.
The relationship between competencies acquired through Swiss academic sports science courses and the job requirements
Authors: Schlesinger T. , Studer F. , Nagel S.
Published: January 2015

In view of the changes in and growing variety of sports‐related occupations, it is highly relevant for educational institutions to know how well the educational contents of their sport science courses meet the professional requirements. This study analyses the relationship between the competencies acquired through academic sports science courses and the requirements of the relevant jobs in Switzerland. The data for this empirical analysis were drawn from a sample of n = 1054 graduates of different academic sport science programmes at all eight Swiss universities. The results show that academic sport science courses primarily communicate sports‐specific expertise and practical sports skills. On the other hand, most graduates consider that the acquisition of interdisciplinary competencies plays a comparatively minor role in sport science education, even though these competencies are felt to be an important requirement in a variety of work‐related environments and challenges.
Peaks cloaked in the mist: The landscape of mammalian replication origins
Authors: Hyrien Olivier
Published: January 2015

Replication of mammalian genomes starts at sites termed replication origins, which historically have been difficult to locate as a result of large genome sizes, limited power of genetic identification schemes, and rareness and fragility of initiation intermediates. However, origins are now mapped by the thousands using microarrays and sequencing techniques. Independent studies show modest concordance, suggesting that mammalian origins can form at any DNA sequence but are suppressed by read-through transcription or that they can overlap the 5′ end or even the entire gene. These results require a critical reevaluation of whether origins form at specific DNA elements and/or epigenetic signals or require no such determinants.
Multiple assembly mechanisms anchor the KMN spindle checkpoint platform at human mitotic kinetochores
Authors: Kim Soonjoung , Yu Hongtao
Published: January 2015

During mitosis, the spindle checkpoint senses kinetochores not properly attached to spindle microtubules and prevents precocious sister-chromatid separation and aneuploidy. The constitutive centromere-associated network (CCAN) at inner kinetochores anchors the KMN network consisting of Knl1, the Mis12 complex (Mis12C), and the Ndc80 complex (Ndc80C) at outer kinetochores. KMN is a critical kinetochore receptor for both microtubules and checkpoint proteins. Here, we show that nearly complete inactivation of KMN in human cells through multiple strategies produced strong checkpoint defects even when all kinetochores lacked microtubule attachment. These KMN-inactivating strategies reveal multiple KMN assembly mechanisms at human mitotic kinetochores. In one mechanism, the centromeric kinase Aurora B phosphorylates Mis12C and strengthens its binding to the CCAN subunit CENP-C. In another, CENP-T contributes to KMN attachment in a CENP-H-I-K–dependent manner. Our study provides insights into the mechanisms of mitosis-specific assembly of the checkpoint platform KMN at human kinetochores.
