Prediction of fracture density using genetic algorithm support vector machine based on acoustic logging data
Authors: Li Tianyang , Wang Ruihe , Wang Zizhen , Zhao Mingyuan , Li Lei
Published: November 2017

Existing methods of well-logging interpretation cannot be applied accurately for the exploration and evaluation of carbonate reservoirs because of the fracture development. Based on the fracture density obtained by core analysis in a carbonate reservoir located in the Ordos Basin, in northwest China, three types of fracture density (low fracture density, medium fracture density, and high fracture density) of the target formation were identified. We investigated the effect of fractures on acoustic logging signals in the time and frequency domains by the Hilbert-Huang transform (HHT) and extracted 11 features in the time domain and nine features in the frequency domain. Then, we reduced the features in the time and frequency domain to three principal components by principal component analysis. Finally, a new prediction model of genetic algorithm-support vector machine method based on HHT of acoustic logging data was reported to predict the fracture density. The results indicate that the fracture density has a greater effect on the attenuation of intrinsic mode function 2 (IMF2) and IMF3 components for three different types of formation by empirical-mode decomposition analysis. The energy of the Stoneley wave and S-wave has higher sensitivity than the P-wave. Compared with the time domain, the distribution in the high-frequency domain has a greater correlation with fracture density by the Hilbert spectrum and marginal spectrum. The correlation coefficients between the fracture density and nine features in the frequency domain ([Formula: see text]) are better than the coefficients with 11 features in the time domain ([Formula: see text]). The core analysis and interpretation of resistivity image logging support the validity and effectiveness of our model. The prediction accuracy using the features in the frequency domain can reach to 82%–90%, which is much higher than using the features in the time domain with accuracy of 52%–59%. The application with more information of original acoustic logging data in our model not only avoid the error in velocity picking but also point the direction for the future prediction.
Velocity model building by waveform inversion of early arrivals and reflections: A 2D case study with gas-cloud effects
Authors: Zhou Wei , Brossier Romain , Operto Stéphane , Virieux Jean , Yang Pengliang
Published: November 2017

Joint full-waveform inversion (JFWI) combines reflection waveform inversion (RWI) and early-arrival waveform inversion to build a large-scale velocity model of the subsurface from long-offset data. The misfit function of JFWI requires an explicit separation between the short-spread reflections and early arrivals, the feasibility of which is illustrated with a real data case study. JFWI is alternated with a waveform inversion/migration of short-spread reflections to provide a short-scale impedance model. This model is needed for building the sensitivity kernel of RWI along the two-way reflection paths. The large-scale velocity macromodel built by JFWI can be used as the initial model for classic FWI to enrich the high-wavenumber content of the subsurface model. We have developed an application of this workflow to a real 2D ocean bottom cable (OBC) profile across a gas cloud in the North Sea to review its main promises and pitfalls. Viscoacoustic VTI seismic modeling allows us to account for attenuation and anisotropy effects in a passive way during JFWI and FWI. Using a smoothed version of an existing traveltime tomographic model as the initial model, we first find that the JFWI velocity macromodel is more accurate than the RWI counterpart thanks to the key contribution of the diving waves. Second, we find that the large-scale velocity model updated by JFWI provides a more accurate initial model for classic FWI than does the original smoothed tomographic model. However, because a data difference-based misfit function is used, 2D JFWI still suffers from cycle skipping when a crude 1D velocity model is used as the initial model; therefore, more robust misfit function should be designed to mitigate cycle skipping.
Recall of structured radiology reports is significantly superior to that of unstructured reports
Authors: Buckley Bryan W , Daly Leslie , Allen Grainne N , Ridge Carole A
Published: November 2017

Objective:

To measure recall of structured compared with unstructured radiology reports.

Methods:

Institutional review board approval was obtained. Four hypothetical radiology reports, two structured and two unstructured reports, were created for the purposes of this study by an experienced consultant radiologist. The reports, each followed immediately by a multiple-choice questionnaire listing possible diagnoses from the report, were distributed to the members of two national physician associations using a web-based survey tool. Based on the number of correct responses, correct critical findings and incorrect responses, rates per number of potential diagnoses were calculated for each individual and averaged. The paired sign test compared results between structured and unstructured reports.

Results:

148 respondents completed the survey, 126 (85.1%) of whom were physicians. The mean percentage of incorrect diagnoses was 4.5% for structured reports compared with 16.7% for unstructured reports (p < 0.001). The average rate of critical diagnosis recall was 82.7% for structured reports and 65.1% for unstructured reports (p < 0.001). The average percentage of all diagnoses detected for structured compared with unstructured reports was 64.3 and 59.0%, respectively (p = 0.007).

Conclusion:

Recall of structured radiology reports is significantly superior to recall of unstructured reports immediately after reading the report.

Advances in knowledge:

A structured radiology report format can positively impact the referring clinician’s ability to recall the critical findings with statistically significance.

Script doctoring and authorial control in Hollywood and independent American cinema
Authors: Bordino Alex W.
Published: November 2017

This study seeks to elucidate the role of the ‘script doctor’ in both Hollywood and independent American cinema. It attempts to reveal how script doctors, considering them to be cultural producers in their own right, create meaning in their doctored works. It poses several questions: Who are script doctors and how do they perceive their work as meaningful or not? Has this changed over time? Is this different for independent film producers, where the practice may be less formalized and institutionalized? Is the role of script doctor perceived in a certain way, either as a prestigious practice only conducted by seasoned screenwriters or as a lower form of professional writing? Finally, does their role in the production process problematize how we attribute authorship to some writers and not others? Archival material will be analysed in order to trace this practice historically, while this study will also draw from my own personal experience editing scripts for independent filmmakers, thus attempting to compare how historical, institutional script development practices may differ from independent practices where the role may be defined differently, in my case as a ‘script editor’, not a ‘script doctor’. Beyond considering script doctors as cultural producers who create meaning in and through their work, this study shall additionally examine how and where credit is given to various participants involved in the writing process, problematizing typical authorial associations.

Key themes in mobile learning: Prospects for learner-generated learning through AR and VR
Authors: Aguayo Claudio , Cochrane Thomas , Narayan Vickel
Published: November 2017

This paper summarises the findings from a literature review in mobile learning, developed as part of a 2-year six-institution project in New Zealand. Through the development of a key themes codebook, we address selected key themes with respect to their relevance to learner-generated learning through emerging technologies, with attention to mobile augmented reality and mobile virtual reality. We see that these two current mobile learning affordances, complemented though relevant approaches to research and practice in mobile learning such as design-based research and connected social learning, are critical to reconceptualise learning through mobile devices. We conclude that mobile learning still requires the theories, methodologies, and practices of its own as a field. We also see a need for mobile learning to be conceptualised around ever-changing learning affordances and educational settings, rather than focusing on static structures such as content-delivery approaches, while embedding it within the scholarship of technology enhanced learning.

The macrophyte plant distribution in some aquatic habitats and their availability for monitoring the PAH contamination were investigated in Kocaeli Province of Turkey. Alisma plantago-aquatica L. was collected to evaluate polyaromatic hydrocarbon (PAH) contamination in four aquatic habitats located nearby or distant to the industrial facilities and populated city center. Concentrations of eight PAH congeners were measured in A. plantagoaquatica leaves using gas chromatography. PAH sources were estimated using the following ratios, Fluoranthene / (Fluoranthene + Pyrene), Benzo(a)anthracene / (Benzo(a) anthracene + Chrysene) and Anthracene / (Anthracene + Phenanthrene) and were found to be pyrogenic-sourced in all stations. Since the ratios of congeners indicate the pyrogenic contamination, atmospheric deposition can be considered as the main pathway for PAH transportation. The highest ΣPAH concentration (798 μg kg

Medical information system (MIS) is at the heart of information technology (IT) implementation policies in healthcare systems around the world. Different architecture and application models of MIS are developed. Despite of obvious advantages and benefits, application of MIS in everyday practice is slow. On the background of analysis of the existing models of MIS in Georgia has been created a multi-user web-based approach. This article will present the architecture of the system and its application for cytology quality assurance programs. Five hundred Georgian language electronic medical records from the cervical screening activity illustrated by images were selected for quality assurance program. The primary goal of the MIS is patient management. However, the system can be used for quality assurance programs. The ideal of healthcare in the information age must be to create a situation where healthcare professionals spend more time creating knowledge from medical information and less time managing medical information. The application of easily available and adaptable technology and improvement of the infrastructure conditions is the basis for eHealth applications. The MIS is perspective and actual technology solution. It can be used for cytology quality assurance programs.

This article presents the dual-band of a single patch antenna that can operate at a frequency of 2.47 to 5.04 GHz, which is available in WLANs (IEEE 802.11). The beam pattern of the antenna can be switched by changing the position of shorted-circuit points at each edge of the antenna. The advantage of the proposed antenna is that it is a simple structure which is small in size, weighs little and has an easily adjustable beam. In addition, the antenna is tested under real circumstances using the existing WLAN infrastructure. The results confirm that the signal strength can be improved when the proposed switched beam antenna is utilized.

Blocks to, and building blocks of, narrativity: Fragments, anecdotes, and narrative lines in David Markson’sReader’s block
Authors: Keskinen Mikko
Published: November 2017

David Markson’sReader’s block(1996) consists of 193 pages of quotations, anecdotes, names, and fragments. The book bears the paratext “A novel,” and the work has indeed been read as a narrative whole, in which “an aging author [...] contemplates the writing of a novel.” By being out of ordinary and therefore worth of telling, the anecdotes or curiosities seemingly fulfill the requirements of a “natural” narrative as defined by Monika Fludernik (1996). However, a mass of such mini-narratives, mixed with even more fragmentary texts, seems to defy narrativity (and tellability). In my reading, the ostensive block to narrativity also functions as its very building block. Thanks to polysemy,blockcan relate to a block of a city, of stone at a gravesite, of text on a printed page, and of index cards. The seemingly dispersed fragments begin to gravitate around these semantic blocks and yield discrete but intertwining narrative lines. The very text claiming to deal with blockages performatively, as a finished book, testifies to the opposite: the mass of texts and plans proves that the ability to work on writing is not lost. Blocks that obstruct also construct, and the demediated novelistic medium still mediates as a form and repurposed content.
Framing absence: A narratology of the empty page
Authors: Domsch Sebastian
Published: November 2017

Narrative experimentation has seen many forms, but among the most radical strategies might be the complete absence of text. Printed text is largely determined through its physical presence on the page, it defines itself by where it is, and the performance of the present text determines the flow of narrative time. Silences and absences are usually created semantically, with a present text telling about an absence. Only rarely do texts stage emptiness through the actual absence of text. But when they do, they considerably expand the narrative range of expression of the printed page. In this paper I will look at the narratology of the empty page by analyzing and comparing a number of texts that stage or emphasize the actual absence of text from the page. There are some narrative texts that use their medial form as text printed on a page and bound in a codex not only to narrate absences, but also to stage them outside of the text proper, or rather, through the actual absence of text leading the recipient’s awareness to the page as a frame of reference that potentially carries semantic value. I will contrast different techniques of “framing absence” in texts by David Mitchell (number9dream), Jonathan Safran Foer (Tree of codes), B. S. Johnson (House mother normal) and Mark Z. Danielewski (House of leaves). These examples will show how literary texts can use their own mediality and materiality to reflect on the general relation between all three.

Published: November 2017

The normal life of a transformer is well above 25 years. The economical operation of the distribution system has its roots in the equipments being used. The economy being such, that it is financially advantageous to replace transformers with more than 15 years of service in the second perennial market. Testing of transformer is required, as its an indication of the extent to which a transformer can comply with the customers specified requirements and the respective standards (IEC 60076-3). In this paper, induced over voltage testing on transformers using enhanced Z source inverter is discussed. Power electronic circuits are now essential for a whole array of industrial electronic products. The bulky motor generator set, which is used to generate the required frequency to conduct the induced over voltage testing of transformers is nowadays replaced by static frequency converter. First conventional Z-source inverter, and second an enhanced Z source inverter is being used to generate the required voltage and frequency to test the transformer for induced over voltage test, and its characteristics is analysed.
Optimisation of amplitude distribution of magnetic Barkhausen noise
Authors: Pal’a Jozef , Jančárik Vladimír
Published: November 2017

The magnetic Barkhausen noise (MBN) measurement method is a widely used non-destructive evaluation technique used for inspection of ferromagnetic materials. Besides other influences, the excitation yoke lift-off is a significant issue of this method deteriorating the measurement accuracy. In this paper, the lift-off effect is analysed mainly on grain oriented Fe-3%Si steel subjected to various heat treatment conditions. Based on investigation of relationship between the amplitude distribution of MBN and lift-off, an approach to suppress the lift-off effect is proposed. Proposed approach utilizes the digital feedback optimising the measurement based on the amplitude distribution of MBN. The results demonstrated that the approach can highly suppress the lift-off effect up to 2 mm.
Construction for obtaining trellis run length limited error control codes from convolutional codes

Published: November 2017

Recently a new construction of run length limited block error control codes based on control matrices of linear block codes was proposed. In this paper a similar construction for obtaining trellis run length limited error control codes from convolutional codes is described. The main advantage of it, beyond its simplicity is that it does not require any additional redundancy except the one which is already contained in the original convolutional error control code. One example is presented how to get such a code from a convolutional low density parity check code.
Laser induced adjustment of the conductivity of rare earth doped Mn-Zn nanoferrite
Authors: El-Dek S. I. , Ahmed M. A. , Eltawil Alaaeldin A.
Published: November 2017

Two series of Mn-Zn nanoferrites (namely Mn1-xZnxFe2O4and Mn1-xZnxFe2-yRyO4) were synthesized using standard ceramic technique. X-ray diffraction and FT-IR were employed in the chacterization of the nanopowder. The X-ray density for each sample increased after laser irradiation which was correlated with the decrease in the unit cell volume. The study involved the thermal and frequency variation of the dielectric constant and AC conductivity of the investigated samples before and after laser irradiation. The later altered the conductivity by decreasing its value for the rare earth doped samples except for the Sm3+doped one. The results suggested the exploitation of Mn-Zn doped rare earth nanoferrites in many technological applications demanding high resistivity.

Published: November 2017

During a midwinter cruise north of 80°N to Rijpfjorden, Svalbard, the composition and vertical distribution of the zooplankton community were studied using two different samplers 1) a vertically hauled multiple plankton sampler (MPS; mouth area 0.25 m2, mesh size 200 μm) and 2) a horizontally towed Methot Isaacs Kidd trawl (MIK; mouth area 3.14 m2, mesh size 1500 μm). Our results revealed substantially higher species diversity (49 taxa) than if a single sampler (MPS: 38 taxa, MIK: 28) had been used. The youngest stage present (CIII) of Calanus spp. (including C. finmarchicus and C. glacialis) was sampled exclusively by the MPS, and the frequency of CIV copepodites in MPS was double that than in MIK samples. In contrast, catches of the CV-CVI copepodites of Calanus spp. were substantially higher in the MIK samples (3-fold and 5-fold higher for adult males and females, respectively). The MIK sampling clearly showed that the highest abundances of all three Thysanoessa spp. were in the upper layers, although there was a tendency for the larger-sized euphausiids to occur deeper. Consistent patterns for the vertical distributions of the large zooplankters (e.g. ctenophores, euphausiids) collected by the MPS and MIK samplers provided more complete data on their abundances and sizes than obtained by the single net. Possible mechanisms contributing to the observed patterns of distribution, e.g. high abundances of both Calanus spp. and their predators (ctenophores and chaetognaths) in the upper water layers during midwinter are discussed.

Twenty six specimens of the polychaete Eulalia picta were found in fine-grained sand tubes. Material was collected in the Antarctic fjord, Admiralty Bay at the depth of about 100 m. The comparison of tube sediment with the sediment composition at the collection site demonstrated that tubes were created with a high degree of particle selection. Our findings might suggest presence of the tube-building behavior in E. picta or show that this species is a highly specialized predator crawling into the tubes of other sessile polychaetes and uses their tubes as protective cases.
Algal pigments in Hornsund (Svalbard) sediments as biomarkers of Arctic productivity and environmental conditions

Published: November 2017

Pigments (chloropigments-a and carotenoids) in sediments and macroalgae samples, collected in Hornsund, in July 2015 and July 2016, were analysed (HPLC) in this work. In spite of the aerobic conditions and the periodic intensive solar irradiation in the Arctic environment, neither of which favour pigment preservation in water column and surface sediments, our results indicate that these compounds can provide information about phytoplankton composition, primary production and environmental conditions in this region. The sum of chloropigments-a, a marker of primary production, in the Hornsund sediments varied from 0.40 to 14.97 nmol/g d.w., while the sum of carotenoids ranged from 0.58 to 8.08 nmol/g d.w. Pheophorbides-a and pyropheophorbides-a made up the highest percentage in the sum of chloropigments-a in these sediments, supplying evidence for intensive zooplankton and/or zoobenthos grazing. Among the carotenoids, fucoxanthin and its derivatives (19’-hexanoyloxyfucoxanthin and 19’-hexanoyloxy-4-ketofucoxanthin) contributed the highest percentage, which points to the occurrence mainly of diatoms and/or haptophytes in the water. The pigment markers show that the input of macroalgae to the total biomass could be considerable only in the intertidal zone.

Rediscovery of Armenian Birch Mouse, Sicista Armenica (Mammalia, Rodentia, Sminthidae)
Authors: Rusin M. , Ghazaryan A. , Hayrapetyan T. , Papov G. , Martynov A.
Published: November 2017

Armenian birch mouse is one of the least known species of mammals of Eurasia. It was described as a separate species based on three specimen trapped in 1986. From that time no other Sicista was found in Armenia. In 2015 we surveyed Central and Northern Armenia and established that probably population from the type locality is lost. But we found another population on Sevan Pass. Due to our observations the species meets Critically Endangered B2a+bIV category of the IUCN Red List.
PPP – kein relevanter Beitrag zur Lösung der Infrastrukturprobleme in Deutschland
Authors: Eisenkopf Alexander
Published: November 2017

Public Private Partnerships (PPPs) are the cooperation between the state and the private sector in the planning, realization, financing and operation of traditionally public services. In the area of road infrastructure, they are implemented as F-, A- or V-models. Statements on the profitability of PPP projects are always subject to case studies. As a rule, financing costs for PPPs will be higher than for conventional procurement. Cost savings in PPP, on the other hand, are empirically relatively low, since independent and transparent studies hardly exist. Finally, there are considerable doubts as to whether PPP projects contribute to an increase in efficiency from a macroeconomic perspective and deliver a relevant contribution to the solution of infrastructure problems in Germany. This seems especially to be true with respect to the intended establishment of a federal infrastructure company for motorways.
Entscheidung in Dien Bien Phu. Niederlage einer Kolonialmacht im Kontext des Kalten Krieges
Authors: Pattinger Thomas
Published: November 2017

Dien Bien Phu is an inconspicuous place among the undulating jungle of Vietnam next to the Laotian border. On March 13th the Viet Minh started the decisive battle against the French fortress after monumental preparations and fought the former colonial power sacrificially. On May 7th the combat and the First Indochina War were settled. France experienced its Stalingrad in this lossy battle and Vietnam gained its independence, if only briefly. It is the end of a colonial empire, but the First Indochina War also marks a hot period in consideration of the Cold War.
„Wir kommen unter die Metzger“. Die Umsetzung des nationalsozialistischen Euthanasieprogramms im Reichsgau Tirol-Vorarlberg
Authors: Walli Thomas
Published: November 2017

The following bachelor thesis is about the Aktion T4 in Nazi Germany and its execution in the Reichsgau Tirol-Vorarlberg. Starting with an overview of the most important ideological and racial influences of the Nazis, like the social Darwinism or the theories about eugenics of the late 19th century, it focuses on the state-wide Aktion T4. From 1939 on the National Socialist regime tried to kill all persons with a mental or physical handicap. One of the main hospitals in western Austria was the Heil- und Pflegeanstalt Hall in Tirol. The paper examines the role of Hall within the whole Aktion T4.
Von Fakiren, Bajaderen und Maharadschas. Der koloniale Blick in der frühen Porträtfotografie Indiens
Authors: Buck Maria
Published: November 2017

This seminar paper analyzes 19th century portrait photographs in British-India, which were mainly made by and addressed at British citizens. Regarding the wide range of genres, it can be shown that these photographs hardly give a realistic image of India, but instead reflect the contemporaneous British view on the colony and its native inhabitants. Photography was therefore an essential instrument of colonial policy. By creating a culturally inferior “other”, it helped legitimating the British rule over India.
Schloss Hartheim – von der Pflege- zur Tötungsanstalt: Historischer Abriss und exemplarische Quellenarbeit mit Briefen von Angehörigen der Ermordeten
Authors: Tapfer Julia
Published: November 2017

Die vorliegende Arbeit beschäftigt sich mit Schloss Hartheim in Linz und dessen Weg von der Pflege- zur Tötungsanstalt. In einem einleitenden Kapitel soll der Kontext der Ermordungen von behinderten Menschen in Hartheim erschlossen werden, weshalb die „Aktion T4“ und die Organisation des Tötens anhand ausgewählter Fachliteratur erklärt werden. Im folgenden Kapitel wird der Fokus auf Hartheim gelegt und dessen Rolle in der NS-Tötungsmaschinerie erläutert, ein Unterkapitel befasst sich auch mit Hartheim als Gedenkort. Im abschließenden Kapitel wird ein besonderer Aspekt der NS-Euthanasie anhand einer kleinen Quellenstudie thematisiert, nämlich die Reaktion der Angehörigen von Ermordeten.
Der Nazis neue Kleider: Die Vereinnahmung jugendlicher Subkulturen durch die extreme Rechte
Authors: Leo Tobias
Published: November 2017

Far right parties, organisations and movements try to usurpate youth subcultural movements. As a result, Skinheads are primarily xenophobic and racist thugs for the public and media, although this subculture in reality is very heterogeneous. But it is true that right-wing extremist Skinheads are a large part of it. Today the Autonomous Nationalists try to conquer and copy left subcultures, but much more subtle and on a broad social base. The focus of this work is the acquisition of the Skinhead subculture and the attempt to do the same at left movements by the extreme right. As an explanatory model, the Hegemony Theory of Antonio Gramsci is used here.
Die getrennte Erinnerung. Der Resistenza-Mythos in Italien von 1943 bis heute: Ursprünge – Wandel – Ausblick
Authors: Walli Thomas
Published: November 2017

The following bachelor thesis is about the Resistance myth in postwar Italy and its transition during the last seven decades. Starting with an overview of its origins in the first years after the war, the paper describes its transition from an important reference point for all political parties (except the neofascist MSI) towards a controversial locus of memory. It then puts a special emphasis on the last two years, while a center left-wing coalition has been ruling and reinterpreting the myth – again.

Diabetes is the commonest cause of end-stage renal disease; over a quarter of patients who are on dialysis in the UK have diabetes. Diabetic kidney disease is associated with high cardiovascular morbidity and mortality. Hypertension is a modifiable risk factor for cardiovascular complications and progression of diabetic kidney disease.The Association of British Clinical Diabetologists and the Renal Association have jointly developed guidelines for management of hypertension through different stages of diabetic kidney disease. Here we present a summary of clinical practice recommendations, audit standards, and areas that require further research.
