Surge Limit Prediction for Automotive Air-Charged Systems
Authors: Bühler Johannes , Leichtfuß Sebastian , Schiffer Heinz-Peter , Lischer Thomas , Raabe Simon
Published: October 2019

Compressor surge has been investigated and predicted since the early days of turbomachinery research. Experimental testing of turbomachinery applications is still needed to determine whether stable compressor operation is possible in the expected application regime. Measuring compressor maps and operating ranges on hot gas test stands is common. The test benches are designed and optimized to ensure ideal inflow and outflow conditions as well as low measurement uncertainty. Compressor maps are used to match turbocharger and application. However, a shift in surge limit, caused by the piping system or application, can only be adequately addressed with full engine tests. Ideal measurements use the corresponding piston engine in the charged-air system. This can only take place in the development process, when surge detection is unfavorable from an economic perspective. The surge model for turbochargers presented here is an extension of the Greitzer’s surge model, which considers the effect of inlet throttling. Application components, such as air filters, pipe elbows and flow straighteners, reduce pressure in front of the compressor and flow conditions might differ from those in laboratory testing. Experimental results gathered from the hot gas test stand at TU Darmstadt indicate strong variation in surge limit, influenced by inlet throttling. An extension to the surge model is developed to explain the observed phenomena. The model was validated using extensive experimental variations and matches the experienced surge limit shift. Additional measurements with a piston engine downstream of the turbocharger demonstrated the validity of the surge model. The results also show that surge is a system-dependent phenomenon, influenced by compressor aerodynamics and boundary conditions.
A Contrast-Guided Approach for the Enhancement of Low-Lighting Underwater Images
Authors: Porto Marques Tunai , Branzan Albu Alexandra , Hoeberechts Maia
Published: October 2019

Underwater images are often acquired in sub-optimal lighting conditions, in particular at profound depths where the absence of natural light demands the use of artificial lighting. Low-lighting images impose a challenge for both manual and automated analysis, since regions of interest can have low visibility. A new framework capable of significantly enhancing these images is proposed in this article. The framework is based on a novel dehazing mechanism that considers local contrast information in the input images, and offers a solution to three common disadvantages of current single image dehazing methods: oversaturation of radiance, lack of scale-invariance and creation of halos. A novel low-lighting underwater image dataset, OceanDark, is introduced to assist in the development and evaluation of the proposed framework. Experimental results and a comparison with other underwater-specific image enhancement methods show that the proposed framework can be used for significantly improving the visibility in low-lighting underwater images of different scales, without creating undesired dehazing artifacts.
Optimal Resource Allocation Model and Algorithm for Elastic Enterprise Applications Migration to the Cloud
Authors: Li Shiyong , Zhang Yue , Sun Wei
Published: October 2019

Cloud computing has been widely used in various industries in recent years. However, when migrating enterprise applications into the cloud, enterprise users face a problem with minimizing migration time and cloud resource providers face a dilemma of resource allocation problem, with the objective of maximizing the migration utility of enterprise users while minimizing the cost of cloud resource providers. In order to achieve them, this paper considered cloud migration objectives including cloud migration time, cloud migration utility, and cloud data center cost, and proposed a resource allocation model for enterprise applications migration into the cloud. The model is divided into two stages: the bandwidth allocation for enterprise applications migration to the cloud and the physical resource allocation of cloud resource providers for enterprise applications deployment into the cloud. In the first stage, we aim to minimize the cloud migration time for enterprise applications, and propose a scheme of bandwidth allocation for each component of applications. In the second stage, we present the resource allocation of cloud resource providers and propose a gradient-based algorithm which can achieve optimal resource allocation. Finally, we give some numerical simulation results to illustrate the performance of the proposed algorithm.
Numerical Results for Linear Sequential Caputo Fractional Boundary Value Problems
Authors: Sambandham Bhuvaneswari , Vatsala Aghalaya S. , Chellamuthu Vinodh K.
Published: October 2019

The generalized monotone iterative technique for sequential 2 q order Caputo fractional boundary value problems, which is sequential of order q, with mixed boundary conditions have been developed in our earlier paper. We used Green’s function representation form to obtain the linear iterates as well as the existence of the solution of the nonlinear problem. In this work, the numerical simulations for a linear nonhomogeneous sequential Caputo fractional boundary value problem for a few specific nonhomogeneous terms with mixed boundary conditions have been developed. This in turn will be used as a tool to develop the accurate numerical code for the linear nonhomogeneous sequential Caputo fractional boundary value problem for any nonhomogeneous terms with mixed boundary conditions. This numerical result will be essential to solving a nonlinear sequential boundary value problem, which arises from applications of the generalized monotone method.
Non-Stationary Acceleration Strategies for PageRank Computing
Authors: Migallón Héctor , Migallón Violeta , Penadés José
Published: October 2019

In this work, a non-stationary technique based on the Power method for accelerating the parallel computation of the PageRank vector is proposed and its theoretical convergence analyzed. This iterative non-stationary model, which uses the eigenvector formulation of the PageRank problem, reduces the needed computations for obtaining the PageRank vector by eliminating synchronization points among processes, in such a way that, at each iteration of the Power method, the block of iterate vector assigned to each process can be locally updated more than once, before performing a global synchronization. The parallel implementation of several strategies combining this novel non-stationary approach and the extrapolation methods has been developed using hybrid MPI/OpenMP programming. The experiments have been carried out on a cluster made up of 12 nodes, each one equipped with two Intel Xeon hexacore processors. The behaviour of the proposed parallel algorithms has been studied with realistic datasets, highlighting their performance compared with other parallel techniques for solving the PageRank problem. Concretely, the experimental results show a time reduction of up to 58.4 % in relation to the parallel Power method, when a small number of local updates is performed before each global synchronization, outperforming both the two-stage algorithms and the extrapolation algorithms, more sharply as the number of processes increases.

Published: October 2019

The present work introduces the application of rational Chebyshev collocation technique for approximating bio-mathematical problems of continuous population models for single and interacting species (C.P.M.). We study systematically the logistic growth model in a population, prey-predator model: Lotka-Volterra system (L.V.M.), the simple two-species Lotka-Volterra competition model (L.V.C.M.) and the prey-predator model with limit cycle periodic behavior (P.P.M.). For testing the accuracy, the numerical results for our method and others existing methods as well as the exact solution are compared. The obtained numerical results indicate the ability, the reliability and the accuracy of the present method.
Targeted High-Throughput Sequencing Identifies Predominantly Fungal Pathogens in Patients with Clinically Infectious, Culture-Negative Endophthalmitis in South India
Authors: Gandhi Jaishree , Jayasudha Rajagopalaboopathi , Naik Poonam , Sharma Savitri , Dave Vivek Pravin , Joseph Joveeta
Published: October 2019

To evaluate the clinical utility of high-throughput sequencing (HTS) approach-based analysis of the bacterial and fungal genome in vitreous fluids from patients clinically diagnosed as endophthalmitis, we subjected 75 vitreous fluids from clinically presumed infectious endophthalmitis patients to high-throughput sequencing (Illumina HiSeq 2500) after DNA extraction and amplification of the 16S rRNA for the detection of bacteria, and ITS 2 region for detection of fungal pathogens. As controls, we included vitreous biopsies from 70 patients diagnosed with other non-infectious retinal disorders. Following the construction of the curated microbial genome database and filtering steps to reduce ambiguousness/contaminants from the environment, the paired reads were analyzed. Our HTS reads revealed in almost all cases the same organism that was grown in culture (bacterial-14/15, fungal 3/3) by conventional microbiological workup. HTS additionally diagnosed the presence of microbes in 42/57 (73.7%) patients who were conventionally negative (fungal pathogens in 36/57, bacterial pathogens in 11/57, including five cases that showed the presence of both bacterial and fungal organisms). Aspergillus sp., Fusarium sp., Exserohilum sp., and Candida sp. were the most predominant genera in our cohort of culture-negative endophthalmitis cases. Heat map based microbial clustering analysis revealed that these organisms were taxonomically similar to the species identified by conventional culture methods. Interestingly, 4/70 control samples also showed the presence of bacterial reads, although their clinical significance is uncertain. HTS is useful in detecting pathogens in endophthalmitis cases that elude conventional attempts at diagnosis and can provide actionable information relevant to management, especially where there is a high index of suspicion of fungal endophthalmitis, particularly in tropical countries. Outcome analyses and clinical trials addressing the success and cost savings of HTS for the diagnosis of endophthalmitis are recommended.
Reappraising Braid after a Quantum Theory of Time
Authors: McKeown Conor
Published: October 2019

Braid’s (Jonathan Blow, 2008) time-bending gameplay allows players to engage with a virtual world in which a player’s perceived ‘past’ can be endlessly rewritten, duration extended, and the ludic arrow of time can be reversed. One could assume that as mistakes can simply be undone, in-game actions cease to have consequences. However, the climax of the game’s narrative arc disrupts our assumption of control over these mechanics and encourages players to reflect on the possible moral implications of actions, both in context of the game world and—through careful invocation of real-world scientific experiments—on everyday life. In this paper, I propose that Braid uses gameplay to explore the difficulty of making moral judgements in a world without an objective past. This is, for the most part, achieved through Braid’s utilization of a specific interpretation of quantum theory—in accordance with the game’s lead designer, Jonathan Blow—that “starts to threaten our very existence” by questioning the possibility of a singular, objective, real ‘past’ and the possibility of a definitive account of past actions. I first argue that the game’s mechanics immerse players in a game world inspired by Blow’s understanding of quantum mechanics. Placing an emphasis on certain technical aspects, I outline how the functioning of the game’s central rewind mechanic—although initially seeming to reinforce visions of our reality consistent with C.D. Broad’s ‘growing block’ theory—questions the notion of an objective past and so resonates strongly with both the work of J.A. Wheeler and an agential realist theory of time. With this understanding in place, I go on to analyze the climax of the game, reading it as an exploration of—and challenge to—the role of a presumed objective ‘past’ in understanding the morality of a given situation. Finally, through a reading of the game’s closing moments, I suggest Braid promotes a turn to individual responsibility for agency; Braid, I argue, recommends one accept the continuing existence and changeability of the past within the present while embracing one’s own role in the shared process of constantly remaking reality and history. As a result, well-intentioned actions in the present are framed as more important than a focus on precedent to predict outcomes, making a cautious suggestion on how one might live without reference to an objective existence. Although I highlight some of the wider ramifications of this at the end of this paper, Braid is far from a fully developed ethical system; it stands, however, as an engaging attempt to formulate a comment on time, temporality and morality through interactive media.

Statistical Analysis of Factors Determining Efficient Use of Foreign Investments in Uzbekistan
Authors: Nazarov Sh. Kh.
Published: September 2019

The article assesses the effective use of investments in fixed assets in Uzbekistan and includes results of regression analysis of the impact of changes in foreign direct investment (FDI) volumes on GDP. The author established that in the previous period economic growth in Uzbekistan was primality caused by domestic investments. At the same time, analysis of the ICOR (Incremental Capital Output Ratio) dynamics and cross-section analysis of the impact of FDI on GDP in 15 transition economies show that misallocation of domestic investment in fixed assets reduces a country’s attractiveness to foreign investors. To assess the synergy effect of the investments, the author used an «Input-Output» model, which allowed to determine industry-specific coefficients of final demand, reflecting the multiplicative effect of investments in fixed assets on GDP growth.The degree of possible FDI influence on Uzbekistan current account balance was determined according to two scenarios, depending onthe capacity of the economy to attract FDI and the degree of export-orientedness.The results of the empirical analysis revealed an urgent need to  strengthen the synergy effect of investment efficiency factors by combining them and simultaneously creating new qualities (emergence). Additionally, based on the revealed highest multiplier effect of the investments in following Uzbekistan’s industries: engineering, chemical and light industry, production of textiles, clothing, and electrical equipment and devices - the author formulated recommendations for increasing their attractiveness to foreign investors.
Les vacances des français en 1964
Authors: Goguel Claude
Published: October 2019

Résultats d'une enquête par sondage sur les vacances 1964, concernant l'ensemble de la population française, y compris les enfants. Une précédente enquête avait eu lieu en 1961.

La proportion des personnes qui prennent des vacances s'est accrue de 10 % en trois ans, la durée moyenne des vacances s' allongeant de 9 % ; le nombre de journées passées par des Français en vacances hors de leur domicile s'est ainsi accru d'environ 20 % depuis 1961.

Les séjours de vacances sont extrêmement concentrés dans le temps : 30 % des départs ont lieu en juillet et 40 % en août, et dans l'espace, essentiellement, dans les départements côtiers et de montagne. Le nombre de séjours à l'étranger s'est accru de 50 %, mais on s'attendait à une croissance encore plus forte. La répartition des séjours par régions et par modes d'hébergement n'a guère varié : on note une régression relative des séjours à l'hôtel et une croissance marquée du nombre de campeurs.

Malgré le progrès apparent très rapide, en fait assez rapide, du phénomène « vacances », les structures se modifient lentement tant en ce qui concerne les caractéristiques des séjours de vacances que les liaisons avec les caractéristiques socio-démographiques des ménages.

Les dépenses consacrées aux vacances varient très fortement avec le niveau de revenu, de 250 F à 1.000 F par personne partie en vacances, soit d'environ 250 F à près de 5.000 F dans l'année, par ménage parti en vacances.
Les salaires dans l'industrie, le commerce et les services en 1965
Authors: Padieu René
Published: October 2019

Les déclarations annuelles «modèle 2460 » sont, actuellement, la source d'information la plus complète sur les salaires, et l'exploitation régulière que l'I.N.S.E.E. en fait depuis quinze ans est devenue traditionnelle. Pourtant, la statistique souffre ici d'être en quelque sorte un sous-produit d'un document administratif à l'origine imparfaitement adapté à cet usage. Toutefois, ce document a pu être progressivement amélioré par la Direction générale des impôts. Divers progrès ont été réalisés dans les méthodes d'exploitation. D'autres aménagements sont à l'étude et l'on pense, d'ici quelques années, disposer là d'un instrument de connaissance très précieux.

Le progrès accompli cette année vise à une meilleure appréciation de l'évolution des salaires individuels. La croissance annuelle des salaires est désormais bien connue. Le fait mérite d'être souligné car il constitue un changement radical d'orientation : on prenait jusqu'ici bien soin de préciser que l'exploitation des «états 2460 » ne fournissait, avec quelque approximation, que des indications sur la structure instantanée des salaires, mais qu'il aurait été vain de vouloir, par ce moyen, apprécier l'évolution des salaires dans le temps.

Dorénavant, les évolutions sont connues au contraire avec plus de précision que les niveaux absolus ou relatifs ; pour ceux-ci, la nouvelle méthode n'apporte aucune amélioration et les réserves habituelles demeurent. La seule restriction à ce qui vient d'être ait concerne l'évolution du salaire moyen des diverses catégories socio-professionnelles : il semble que l'imprécision qui affecte la détermination de celles-ci empêche d'obtenir des chiffres suffisamment sûrs.

De 1964 à 1965, la masse salariale apparaît en augmentation de 7 %, augmentation plus rapide dans le secteur tertiaire que dans l'industrie. Dans le même temps, le salaire moyen par tête croissait de 6 % et ce résultat semble en bon accord avec ceux de l'enquête trimestrielle du ministère des affaires sociales.

Published: October 2019

Colocando a pós-modernidade como pano de fundo desta pesquisa, propomos demonstrar como alunos-professores em formação inicial do curso de Licenciatura em Letras – língua inglesa da Universidade Federal de Campina Grande se engajaram em atitudes críticas/práticas problematizadoras em situação de estudo. Para tanto, empreendemos uma investigação qualitativa, descritivo-analítica e utilizamos respostas a uma entrevista semiaberta e a uma narrativa que lidavam com o processo de formação docente e a relevância da língua inglesa para a prática desses futuros docentes. A análise utilizou as lentes do letramento crítico de viés pós-estruturalista (MENEZES DE SOUZA, 2011a, JORDÃO, 2014, PENNYCOOK, 2012) por ser uma abordagem que centraliza o questionamento, a produção de significação e a construção de conhecimentos situados e parece se alinhar criticamente ao que estamos entendendo enquanto demandas de um mundo pós-moderno (BAUMAN, 2007). Os dados gerados indicam que, em situação de estudo, os participantes manifestam criticidade principalmente a partir de falas que revelam questionamentos, desnaturalização e construção de entendimentos outros em um movimento formativo processual e não linear.
Wear behaviour of duplex (PN+PVD) treated layers produced on X42CR13 steel
Authors: Siddiqui Shiraz Ahmed , Mária Marosné Berkes
Published: September 2019

Wear, corrosion and fatigue are among the most important mechanisms that lead to surface damage, which, ultimately, leads to failure of the components. There is an increasing demand for reducing failures and the related costs due to wear and surface shortcomings of heavily loaded engineering components. Thus, application of surface technologies gives a great potential for saving resources and providing improved technology.

The presented research work involves characterization of a duplex treated i.e. plasma nitrided (at two different temperatures 520 °C, 550 °C) and PVD coated – X42Cr13/W plastic mould tool steel with special emphasis on the ball-on-disc wear behaviour of tested specimens. The objective is to study and evaluate the effect of different nitriding treatments prior to coating on the wear behaviour of specimens having different surface preparations. Also, it has been established that duplex treatment (plasma nitriding + physical vapour deposition [PVD] coating) gives better and improved properties as compared to individual treatments.

Jelen cikk egy fuzzy automatával vezérelt futball szimuláció modelljét mutatja be. A szimuláció ágenseinek (játékosainak) irányítása olyan fuzzy szabálybázisokkal történik, amelyekben csak a tényleges működéshez szükséges, leglényegesebbnek vélt szabályok lettek definiálva. Az ilyen, ritka fuzzy szabálybázisokat a klasszikus fuzzy következtető rendszerek, működésükből adódóan nem tudják alkalmazni. Ellenben, fuzzy szabály interpolációs (Fuzzy Rule Interpolation – FRI) módszer használatával az ágensek ritka fuzzy szabálybázisokkal is vezérelhetők. Ezen munka célja egy olyan modell konstruálása és bemutatása, amely a futball szimuláció vezérléséhez olyan tudásreprezentációt használ, amely emberek által is közvetlenül, könnyen értelmezhető. Erre a célra kiválóan alkalmasak a ritka fuzzy szabálybázisok, önmagyarázó mivoltuknak köszönhetően.

La arteritis de Takayasu (AT ) es una vasculitis de grandes vasos que afecta a la aorta y a sus ramas principales. Los esteroides son la piedra angular del tratamiento; sin embargo, más de la mitad de los pacientes recaen, requiriendo inmunosupresores adicionales. Estudios abiertos han sugerido que metotrexate, ciclofosfamida, azatioprina, micofenolato mofetil y terapia anti-TNF pueden ser útiles en estos casos. Se reporta un caso de una paciente con AT con múltiples recaídas pese a metotrexate, esteroides, rituximab, ciclofosfamida, infliximab, revascularización percutánea y quirúrgica. Se decidió el uso de gammaglobulina endovenosa (IVIg), con control total y sostenido de manifestaciones vasculíticas, suspensión de esteroides y disminución de los reactantes de fase aguda

La porfiria intermitente aguda (PIA) es una enfermedad poco frecuente, considerada huérfana, que se caracteriza por crisis neuroviscerales, el dolor abdominal siendo su síntoma más común, acompañado en muchos casos, de síntomas inespecíficos, haciendo difícil su diagnóstico temprano. El retraso en el diagnóstico y tratamiento de esta entidad puede resultar catastrófico o incluso fatal, provocando daño neurológico a largo plazo o permanente. Reportamos el caso de un adulto joven que consulta en varias ocasiones por dolor abdominal inespecífico y 24 horas después de la admisión desarrolla inestabilidad autonómica simpática con cifras tensionales elevadas y taquicardia. Posteriormente debilidad muscular que evoluciona hasta cuadriplejía e hiponatremia con criterios para secreción inadecuada de hormona antidiurética (SIADH). Estos datos, junto con coloración rojiza en orina, llevan al diagnóstico de porfiria. Presentamos las características clínicas y bioquímicas enfatizando la importancia de incluir la porfiria dentro de los diagnósticos diferenciales de dolor abdominal y disautonomía de causa indeterminada.

The introductory text in the narrative imagination (Sonallah Ibrahim)
Authors: Witwit Widad
Published: September 2019

The introductory text is imaginative, carried out by a fictional character assigned to the author the initiation status, which makes this study the field of operation. Because the initiation is so important as a textual threshold at which two worlds, real and imagined, are entrusted to entice the reader to the world of the text, the writers sought to enrich it by suggestive cards with concentrated interpretability. The opening of the modern narrator has become - consciously - the code for reading the text and imbibing its climates and environments. If the openings of classical novels by framing the investigative and descriptive spatial time, the star of the new novel begged open dynamic where the overlap of possibility of the event and the harbingers of the fates of the characters and visions that make up the text and semantic mandates.

Penelitian ini menggunakan sudut pandang feminisme yang mencakup pembahasan mengenai hubungan seksual, femme fatale, dan teori film feminis. Kajian ini menggunakan metodologi interpretatif yakni suatu pendekatan tafsir yang menggunakan ”teks” sebagai analogi atau model yang memandang, memahami, dan menafsirkan suatu kebudayaan atau gejala sosial budaya tertentu. Kesimpulan dari penelitian ini adalah perempuan dalam film sundel bolong merupakan objek dalam hubungan seksual dan kematiannya merupakan kebangkitannya dalam wujud hantu. Sundel Bolong yang kecewa terhadap laki-laki dan frustrasi muncul sebagai sosok femme fatale dan membalas dendam dengan menggunakan tipu muslihat feminin seperti kecantikan, pesona, dan daya tarik seksual. Penindasan seksualitas perempuan adalah subteks penting dari film horor bertema Sundel Bolong.Kata Kunci:
