Flame Symptom Modelling Near Lean Blowout in a Swirl-Stabilized Gas Turbine Model Combustor

Lean premixed combustion offers a practical approach for the reduction of NOx emissions, but increases the risk of lean burn blow out (LBO) in gas turbines. Flame behavior in terms of stability is simulated in a model gas turbine combustor burning aviation kerosene at atmospheric pressure. The flame symptom close to LBO, where the flame propagates in the broken-reaction zone (BRZ) regime in double swirl combustor is studied when the main influence parameter of first to second stage air flow ratio is 1:5. Adjusting the dimensionless ratio of oil/air equivalence to 0.35 is identified as significant perturbation source for inducing unstable combustion. Results of simulation show a good agreement with obtained data of other test. KeywordsTurbine lean premixed combustion; Double-stage swirl combustion chamber; Lean blow out Symptom; Numerical simulation.
Electronic Government-Citizen Relationships

Abstract Citizens that already are engaged in online activities are more inclined to connect with their governments electronically. One question that has largely gone unanswered is, Does citizens' use of the Internet to interact with governments facilitate relationships between them and their governments? This is the key issue for e-governance and is under researched. So this research explores citizen perspectives through qualitative interviews. The data is content analyzed using Leximancer. Citizens trust the e-government process but not their governments. Quantitative survey research is needed to confirm these results that are important both for relationship theory and for the working relationships between governments and citizens.
Sexual size dimorphism and the strength of sexual selection in mammals and birds

Background: Sexual selection has been used as a proximate explanation for sexual size dimorphism (SSD) in many taxa, but the relationship between SSD and a quantitative measure of the strength of sexual selection has yet to be tested. Hypothesis: The strength of sexual selection is positively correlated with SSD in birds and mammals. Methods: We used two measures of SSD: the SSD ratio and the size dimorphism index (SDI). The SSD ratio is log(male body mass/female body mass). SDI is the ratio of the larger sex to the smaller sex and minus 1; the resulting value is then made negative for male-biased dimorphism and positive for female-biased dimorphism. Our measure of the strength of sexual selection is the standardized variance in male fitness (I) calculated as the square of the coefficient of variation in male mating or reproductive success, which reflects the maximum potential strength of sexual selection. We carried out a phylogenetic generalized least squares regression (PGLM) of SSD ratio or SDI on I. Results: There was no consistent relationship between SSD and I, as they were strongly positively related in mammals, but not in birds. This may relate to the form of competition (contests vs. display) that is found most often in mammals and birds.

Relationship among Economic Growth, Internet Usage and Publication Productivity: Comparison among ASEAN (Association of Southeast Asian Nations) and World’s Best Countries

Publication productivity, as measured by the number of papers, has been regarded as one of the main indicators of reputation of countries and institutions. Nevertheless, the relationship among research publications, economic growth and World Wide Web in ASEAN countries is still unclear. The main intention of this study was to identify publication productivity among ASEAN and the world’s top ten countries in the last 16 years (1996-2011). This study also aimed at finding the relationship among publication, gross domestic product (GDP) and internet usage. Furthermore, the publication trend in the 10 first Malaysian universities was evaluated for the same periods. Scopus database was used to find the overall documents, overall citations, citations per document and international collaboration from 1996 to 2011 for each country. The World Bank database (World Data Bank) was used to collect the data for GDP and the number of internet users. Moreover, to evaluate 10 top Malaysian universities, the number of published articles, conferences, reviews, and letters for the same periods was collected. The results of this study showed significant differences among ASEAN and top 10 countries regarding publication productivity. Moreover, a positive and significant relationship was observed between indices, GDP and internet usage for these countries. Surprisingly, international collaboration had a significant and negative relationship with economic growth. Malaysia had fewer citations per document (7.64) and international collaboration (36.9%) among ASEAN countries. In conclusion, international collaboration between academic institutes and researchers is influenced by economic growth and access to internet in the countries. Furthermore, publication trends in ASEAN countries are promising. However, policy makers and science managers should try to find different ways to increase the quality of the research publication and to raise citation per document.
A reflexive exploration of two qualitative data coding techniques

In an attempt to help find meaning within qualitative data, researchers commonly start by coding their data. There are a number of coding systems available to researchers and this reflexive account explores my reflections on the use of two such techniques. As part of a larger investigation, two pilot studies were undertaken as a means to examine the relative merits of open coding and template coding for examining transcripts. This article does not describe the research project per se but attempts to step back and offer a reflexive account of the development of data coding tools. Here I reflect upon and evaluate the two data coding techniques that were piloted, and discuss how using appropriate aspects of both led to the development of my final data coding approach. My exploration found there was no clear-cut ‘best’ option but that the data coding techniques needed to be reflexively-aligned to meet the specific needs of my project. This reflection suggests that, when coding qualitative data, researchers should be methodologically thoughtful when they attempt to apply any data coding technique; that they do not assume pre-established tools are aligned to their particular paradigm; and that they consider combining and refining established techniques as a means to define their own specific codes.

Optimal Portfolios with Haezendonck Risk Measures

We deal with the problem of the practical use of Haezendonck risk measures (see Haezendonck and Goovaerts [8], Goovaerts et al. [7], Bellini and Rosazza Gianin [4]) in portfolio optimization. We first analyze the properties of the natural estimators of Haezendonck risk measures by means of numerical simulations and point out a connection with the theory of M-functionals (see Hampel [9], Huber [11], Serfling [19]) that enables us to derive analytic results on the asymptotic distribution of Orlicz premia. We then prove that as in the CVaR case (see Rockafellar and Uryasev [17,18], Bertsimas et al. [6]) the mean/Haezendonck optimal portfolios can be obtained through the solution of a single minimization, and that the resulting efficient frontiers are convex. We conclude with a real data example in which we compare optimal portfolios generated by a mean/Haezendonck criterion with mean/variance and mean/CVaR optimal portfolios.
Presence of the effector gene hop A1 in strains of Pseudomonas syringae pv. actinidiae isolated from France and Italy

Pseudomonas syringae pv. actinidiae (Psa) causes bacterial canker of kiwifruit, a disease that had limited economic impact in Italy before the outbreak of 2009. The strains isolated from Italy since 2008 have different characteristics to those isolated in Japan or Korea or those isolated earlier than 2008 in Italy. This study showed that strains of Psa isolated from France had the cts haplotype I and a BOX-PCR electrophoretic pattern similar to that of strains isolated from Italy after 2008. The effector gene hopA1, which was found previously by PCR to be present only in the strains of the cts haplotype I, was also present in other strains of Psa isolated from Italy. If this effector plays a role in the interaction between Psa and kiwifruit, then the difference in virulence observed between strains of different cts haplotypes cannot be attributed to the presence of this effector.
Solar cycle dependence of the helium focusing cone from SOHO/UVCS observations - Electron impact rates and associated pickup ions

The Ultraviolet Coronograph on board SOHO (UVCS) has observed the 58.4 nm glow of the interplanetary He focusing cone at regular intervals since 1996. The intensity decrease with time already observed during the first two years (Michels et al. [CITE]) has dramatically amplified during the solar activity increase. Intensities seem to reach a plateau in 2001. Using a model of the cone emission which takes into account both photoionization and electron impact ionization of neutral helium we show that the photoionization increase alone cannot explain the observed intensity drop. Data can be fitted if at minimum activity the electron impact ionization rate is the solar cycle average rate predicted by Rucinski & Fahr ([CITE]), and if this rate is increased by a factor of about 3.5 between 1996 and 2001. Assuming the Rucinski and Fahr radial dependence, such high electron impact rates create averaged He + pickup ion (PUI) fluxes which may reach 50% of the fluxes of ions born after photoionization, or 35% of PUI total fluxes, as far as 1 AU from the Sun. In slow and dense solar wind enhancements, in particular in the presence of strong suprathermal tails, PUIs from electron impact could be the dominant species. This could explain a fraction of the observed correlation between He + and H + pickups and anticorrelation of He + fluxes with solar wind velocity.
Truscott's Claims in Giving Corrective Feedback : Does It Matter in EFL Writing Context?

Giving Corrective Feedback in students’ writings has got the center of attention in the recent years. The question of whether to give CF to students or not to do so has become a controversial quest. In this research three Truscott’s claims on giving CF were investigated to EFL students’ writing. For the purpose of this investigation Direct Feedback has been used to draw the conclusion on Truscott’s claims. These claims are: (a) correction may have value for non-grammatical errors but not for errors in grammar; (b) students are inclined to avoid more complex constructions due to error correction; and (c) the time spent on CF may be more wisely spent on additional writing practice to improve writing ability. The obtained results indicated that giving CF to students’ grammatical errors has a significant result on their accuracy improvement. The research also showed that students don’t tend to avoid Complex Structures due to the CF provided on these structures. And finally it indicated that in a class without any provided CF and just with doing exercises on a specific subject the accuracy of students decrease during a writing program.
Breastfeeding policies and practices in health care facilities in the Western Cape Province, South Africa

Abstract The Baby-Friendly Hospital Initiative (BFHI) is a global effort to improve the role of maternity services and to enable mothers to breastfeed their infants, thus ensuring the best start in life for their infants. The foundation for the BFHI is the Ten Steps to Successful Breastfeeding (BF). It has been shown, however, that the selective implementation of only some of the steps may be ineffective and discouraging to successful BF practices. An initial study was therefore conducted to assess the extent of the implementation of the Ten Steps in both public and private maternity facilities. Poor performance for some steps led to a follow-up study to investigate the knowledge and attitudes of health care workers (HCWs) and mothers alike and to evaluate the exclusive BF (EBF) practices of mothers attending private BF clinics. Both studies followed descriptive, cross-sectional designs and were set in the Cape Metropole in the Western Cape. Twenty-six maternity facilities participated in the initial study, for which observation lists were completed and verified by interviewer-administered questionnaires to both HCWs and mothers. Eighteen private BF clinics participated in the follow-up study, which included observations and interviewer-administered questionnaires to 25 HCWs and 64 mothers. During the initial study, lower mean scores were noted for Steps 1, 2, 6 and 10. The overall implementation of the Ten Steps was average. The findings highlighted the importance of the establishment and implementation of BF policies, of appropriate and continuous BF training and better referral systems to ensure initiation and establishment of early BF, EBF practices and support on an ongoing basis to ensure the best start in life for infants.
Household location and self-assessed health among Brazilian adults living in large cities: A multilevel analysis

This paper evaluated the effect of household location on self-assessed health among adults living in large cities, with adjustments for environmental characteristics inside and outside homes and for characteristics of the individual. The results showed that, in comparison with rural areas, urban areas were associated with better self-assessed health levels among adults. Although the adjusted analysis did not show any statistically significant difference in self-assessed health levels between the urban and rural areas, the study showed, independent of whether living spaces were urban or rural and the effect of living conditions in environments inside and outside homes, on self-assessed health levels. Key words: Self-assessed health, household location, multilevel analysis.
Geodesic Lagrangian Monte Carlo over the space of positive definite matrices: with application to Bayesian spectral density estimation

ABSTRACT We present geodesic Lagrangian Monte Carlo, an extension of Hamiltonian Monte Carlo for sampling from posterior distributions defined on general Riemannian manifolds. We apply this new algorithm to Bayesian inference on symmetric or Hermitian positive definite (PD) matrices. To do so, we exploit the Riemannian structure induced by Cartan's canonical metric. The geodesics that correspond to this metric are available in closed-form and – within the context of Lagrangian Monte Carlo – provide a principled way to travel around the space of PD matrices. Our method improves Bayesian inference on such matrices by allowing for a broad range of priors, so we are not limited to conjugate priors only. In the context of spectral density estimation, we use the (non-conjugate) complex reference prior as an example modelling option made available by the algorithm. Results based on simulated and real-world multivariate time series are presented in this context, and future directions are outlined.
First-Year Vitality of Reforestation Plantings in Response to Herbivore Exclusion on Reclaimed Appalachian Surface-Mined Land

Conventional Appalachian surface-mine reclamation techniques repress natural forest regeneration, and tree plantings are often necessary for reforestation. Reclaimed Appalachian surface mines harbor a suite of mammal herbivores that forage on recently planted seedlings. Anecdotal reports across Appalachia have implicated herbivory in the hindrance and failure of reforestation efforts, yet empirical evaluation of herbivory impacts on planted seedling vitality in this region remains relatively uninitiated. First growing-season survival, height growth, and mammal herbivory damage of black locust (Robinia pseudoacacia L.), shortleaf pine (Pinus echinata Mill.), and white oak (Quercus alba L.) are presented in response to varying intensities of herbivore exclusion. Seedling survival was generally high, and height growth was positive for all species. The highest herbivory incidence of all tree species was observed in treatments offering no herbivore exclusion. While seedling protectors lowered herbivory incidence compared with no exclusion, full exclusion treatments resulted in the greatest reduction of herbivore damage. Although herbivory from rabbits, small mammals, and domestic animals was observed, cervids (deer and elk) were responsible for 95.8% of all damaged seedlings. This study indicates that cervids forage heavily on planted seedlings during the first growing-season, but exclusion is effective at reducing herbivory.
Conditionally Additive Utility Representations

Advances in behavioral economics have made decision theoretic models increasingly complex. Utility models incorporating insights from psychology often lack additive separability, a major obstacle for decision theoretic axiomatizations. We address this challenge by providing representation theorems which yield utility functions of the form u(x,y,z)=f(x,z) + g(y,z). We call these representations conditionally separable as they are additively separable only once holding fixed z. Our representation theorems have a wide range of applications. For example, extensions to finitely many dimensions yield both consumption preferences with reference points Sum_i u_i(x_i,r), as well as consumption preferences over time with dependence across time periods Sum_t u_t(x_t,x_{t-1}).
Information and Communication Technology and Customer Satisfaction in the Nigerian Banking Industry

Information and communication technology (ICT) in the Nigerian banking industry is generally believed and seen to have dramatic influence on the level of customer satisfaction in recent times. As a prerequisite for banking efficiency, and indeed customer satisfaction, one wonders whether the current state of ICT in the industry offers the desired level of satisfaction. It is against this backdrop that the study adopts an empirical approach in determining the relationship that exists between the current state of ICT and customer satisfaction in the industry. Four hundred (400) banks’ customers were served with questionnaire, out of which only 391 were used. Regression analysis was used in testing the hypotheses. It was discovered that the present state of ICT had significant influence on customer satisfaction. The following recommendations were therefore made: banks should continually explore the possibility of raising the standard of ICT based systems and services, intensify efforts in meeting up with global operational systems and demonstrate a high sense of reliability, responsiveness and credibility in the application of ICT in their operations.
ANALYTICAL METHODS IN GEOCHEMICAL INVESTIGATIONS OF THE PIERRE SHALE

Spectrographic determinations were made by one speetrographie laboratory on 80 samples of Pierre shale (Late Cretaceous) for 10 elements. The precision of single measurements of these elements, in terms of the coefficient of variation, is: boron, 10 percent; barium, 11; cobalt, 7; chromium, 9; gallium, 20; nickel, 7; scandium, 10; strontium, 13; titanium, 6; and zirconium, 10 percent. Eight of these elements in 10 check samples were determined by a second speetrographie laboratory. The precision, in percent, between laboratories for each indicated element is: boron, 10; barium, 12; cobalt, 16; chromium, 11; gallium, 16; scandium, 12; strontium, 10; and titanium, 10. As computed from data on all 80 samples, the coefficients of variation between determinations by chemical and by speetrographie methods are: barium, 34 percent; cobalt, 12; chromium, 10; nickel, 7; and titanium, 10 percent. The precision of the first speetrographie laboratory on disguised replicate samples is: boron, 6 percent; barium, 8; cobalt, 10; chromium, 5; gallium, 12; nickel, 5; scandium, 12; strontium, 20; titanium, 4; and zirconium, 14 percent.
Web Privacy Census

Most people may believe that online activities are tracked more pervasively now than they were in the past. In 2011, we started surveying the online mechanisms used to track people online (e.g., HTTP cookies, Flash cookies and HTML5 storage). We called this our Web Privacy Census. We repeated the study in 2012. In this paper, we update the study to 2015. Results summary: Our approach uses web crawler software to simulate online browsing behavior, and we record the occurrences of tracking mechanisms for the top 100, 1,000, and 25,000 most popular websites. We found that users who merely visit the homepages of the top 100 most popular sites would collect over 6,000 HTTP cookies in the process (see Top 100 Websites -- Shallow Crawl). Eighty-three percent of cookies are third-party cookies. The homepages of popular sites placed cookies for 275 third-party hosts. In just visiting the homepage of popular sites, we found 32 websites placed 100 or more cookies, 7 websites placed 200 or more cookies, and 6 websites placed 300 or more cookies. We found that Google tracking infrastructure is on 92 of the top 100 most popular websites and on 923 of the top 1,000 websites. This means that Google's ability to track users on popular websites is unparalleled, and it approaches the level of surveillance that only an Internet Service Provider can achieve. -- We repeated a 2012 survey of tracking mechanisms such as HTTP cookies, Flash cookies, and HTML5 storage, used by top 25,000 most popular websites. -- We found that users who merely visit the homepages of the top 100 most popular sites would collect over 6,000 HTTP cookies with 83% being third-party cookies. -- We found that Google tracking infrastructure is on 92 of the top 100 most popular websites and on 923 of the top 1,000 websites, providing Google with a significant surveillance infrastructure online.
