Isolation-based hyperbox granular classification computing
Authors: Liu Hongbing , Zhang Fan , Li Ran , Wu Chang-an
Published: November 2016

Bottom-up and top-down are two main computing models in granular computing by which the granule set including granules with different granularities. The top-down hyperbox granular computing classification algorithm based on isolation, or IHBGrC for short, is proposed in the framework of top-down computing model. Algorithm IHBGrC defines a novel function to measure the distance between two hyperbox hgranules, which is used to judge the inclusion relation between two hyperbox granules, the meet operation is used to isolate the ith class data from the other class data, and the hyperbox granule is partitioned into some hyperbox granules which include the ith class data. We compare the performance of IHBGrC with support vector machines and HBGrC, for a number of two-class problems and multiclass problems. Our computational experiments showed that IHBGrC can both speed up training and achieve comparable generalization performance.

Published: November 2016

This study investigates the role played by parents as mediators of young children’s access and engagement with digital technologies. In Belgium, Germany, Latvia and Portugal, qualitative in-depth interviews were conducted with 10 families in each country, including one child between 6 and 7 years old. Our findings show that parents of young children mainly play the role of ‘gatekeepers’ when it comes to facilitating and constraining access to and use of digital technologies. Parents’ perceptions of the efficacy of digital technologies as responsible entertainment and as educational tools influence the technologies available at home and accessible to the child. These perceptions in turn impact parents’ mediation strategies with regard to children’s actual use of digital technologies, with restrictive mediation – of time and less of content – and supervision applied most. The power exerted by parents over access and use may be understood as a limitation of the children’s rights. On the other hand, parents are not always concerned with the right of protection as they believe – sometimes incorrectly – that they are in control of the content their children are exposed to.
Policing through ‘paperwork’: Foster youth files and archival surveillance in the 21st century
Authors: Lovaas Jessica L
Published: November 2016

Young people in the child welfare system are subjected to intensive and wide-ranging observation, surveillance and documentation practices that have been facilitated by the expanding use of digital technologies. Drawing on qualitative research, this article examines the pervasiveness of these governmental practices and their impacts on the psychological wellbeing and long-term trajectory of young people. Leveraging a Foucauldian framework, this article theorizes a form of 21st-century ‘archival surveillance’ and argues that contrary to the intended goal of utilizing documentation to protect children and minimize liability, the child welfare system’s overuse and misuse of digital technologies violate children’s rights and disproportionally criminalize youth of colour. At the same time, youth appropriate digital technologies in ways that help them survive, connect and resist the inhumane impacts of this archival surveillance.

Published: November 2016

Introduction.

Electrophotonic imaging (EPI), also known as gas discharge visualization, is a technique of capturing images of phenomena not quantifiable by the naked eye. Different sectors at the tip of fingers represent various organs and systems as per the Chinese system of acupuncture. The images from these fingertips can be used to determine the state of health. This is done with the help of a CCD camera fitted in the EPI equipment and the specific software relevant for analysis.

Aim.

To observe the correlation between EPI parameters and fasting blood sugar (FBS) levels in normal, prediabetic, and diabetic study participants.

Materials and Methods.

A total of 102 participants were selected for this study from various yoga camps and Arogyadham at Swami Vivekananda Yoga Anusandhana Samsthana Yoga University, Bengaluru, India. The selected participants belonged to 3groups—normal, prediabetic, and diabetic—depending on the FBS levels. The distribution of participants was 29 normal, 13 prediabetic, and 60 diabetic.

Results.

Regression analysis in the case of prediabetics showed a significant relationship of FBS with pancreas and right kidney. In the case of normal participants, a significant relationship of FBS was found with area and form coefficient of the EPI gram. For diabetics, regression analysis showed significant relationship of FBS with immune organs, left kidney, area, intensity, and entropy of EPI grams.

Conclusion.

FBS correlates differently in the normal, prediabetic, and diabetic groups. In the prediabetic group, correlation of FBS with EPI parameters pancreas and right kidney is noteworthy and in line with latest findings in medical research.

Published: November 2016

Although modern treatments have achieved much progress in blood sugar control in recent decades, evidences indicate that complementary and alternative treatments are very common in diabetic patients. The present study aims to investigate application of complementary and traditional medicines among diabetic patients in Iran in 2016. This was a cross-sectional study done on 294 diabetic patients who were referred to the diabetes clinic and were chosen using convenient sampling. Data were gathered using a demographic characteristics form and a researcher-made questionnaire (for studying application and satisfaction of using some of the complementary and alternative medicines). A total of 88.4% of diabetic patients have used at least one complementary and alternative treatment in the past year. The most common treatment was medicinal plants, which were used by 84.9% of the participants. Sixty-nine percent of the patients were satisfied with using complementary and traditional treatments. This study showed that diabetic patients are very interested in using complementary and alternative medicine.

Objective: The objective of the study is to examine the Champlain. BASETM (Building Access to Specialists through eConsultation) eConsult service’s impact on access to care for older persons. Methods: We conducted a cross-sectional analysis of all eConsult cases submitted between April 15, 2011, and July 31, 2015, in which the patient was above the age of 65 years. Study data consisted of utilization data collected automatically by the service and responses to surveys completed by primary care providers at the conclusion of all eConsult cases. Results: A total of 1,796 cases were submitted for older persons between April 15, 2011, and July 31, 2015, accounting for 21.3% of all cases submitted during the study period. Specialists responded to cases in a median of 0.8 days. In 94% of cases, providers rated eConsult as having great or excellent value for themselves and their patients. Sixty-eight percent of eConsults did not require a face-to-face visit; only 28% of all cases resulted in a referral. Discussion: As they suffer from higher than average rates of comorbid disease and mobility issues, older persons stand to benefit from shorter wait times and better access to care, which the eConsult service can provide.
Mapping deeply buried karst cavities using controlled-source audio magnetotellurics: A case history of a tunnel investigation in southwest China

Published: November 2016

Karst cavity mapping is attracting great interest from engineering geologists because of its relation to the dangerous geohazards faced during engineering construction. Ground-based geophysical methods still face challenges in karst mapping, and concealed karst cavities potentially pose threats to tunnel construction in southwest China. Given the significant contrast in electrical resistivity between karst cavities and their host rocks, geoelectrical methods are widely used for mapping these cavities. We have developed a successful case history of mapping karst cavities on a planned railway route using controlled-source audio magnetotellurics (CSAMT). Scalar CSAMT, with frequencies ranging from 0.5 to 8192 Hz, was used for field data acquisition. A full-frequency domain apparent resistivity correction method was used for near-field corrections. Electromagnetic array profiling (EMAP) filtering was used for topographic and static shift corrections, and the Bostick conversion was used for data interpretation. Our study indicated that the results of the Bostick conversion with EMAP filtering were more acceptable than the results of rapid relaxation inversion and nonlinear conjugate gradient inversion in this case. The G Tunnel is a key tunnel along the Gui-Guang high-speed railway in southwest China. Initial geophysical and engineering geologic results suggest that the bedrock of the survey section of the G Tunnel route is sandstone. A CSAMT survey with three inline sections and three crossline sections over the tunnel route was conducted in two phases to verify the rock conditions of the tunnel route. A concealed karst cavity with a low-resistivity anomaly was found on the tunnel route and was verified by the borehole. Data from the CSAMT survey significantly refined our understanding of the subsurface engineering geologic conditions along the tunnel route.
3D vector finite-element electromagnetic forward modeling for large loop sources using a total-field algorithm and unstructured tetrahedral grids
Authors: Li Jianhui , Farquharson Colin G. , Hu Xiangyun
Published: November 2016

Unstructured tetrahedral grids with local refinement facilitate the use of total-field solution approaches to geophysical electromagnetic (EM) forward problems. These approaches, when combined with the vector finite-element (FE) method and with refinement near transmitters and receivers, can give accurate solutions and can easily handle realistic models with complex geometry and topography. We have applied this approach to 3D forward modeling for fixed- and moving-loop configurations. MUMPS, a direct solver, was used to solve the linear system of equations generated by FE analysis. A direct solver is particularly suited to the moving-loop configuration for which the right side is different for every transmitter loop, but for which the coefficient matrix is unchanged. Therefore, the coefficient matrix need only be factorized once, and then the system can be solved efficiently for all different right sides. We compared our results with several typical scenarios from the literature: a conductive brick in a homogeneous half-space and a complex conductor at a vertical contact both for fixed-loop configurations, and a homogeneous half-space for a moving-loop configuration. We also evaluated results for the massive sulfide ore deposit of the Ovoid Zone at Voisey’s Bay, Labrador, Canada, for which we considered fixed- and moving-loop configurations. This model also provides an illustration of the complex vortex current systems that are generated by time-domain EM methods within highly conductive ore bodies in a resistive host.
Joint petrophysical interpretation of multidetector nuclear measurements in the presence of invasion, shoulder-bed, and well-deviation effects
Authors: Ortega Edwin , Luycx Mathilde , Torres-Verdín Carlos , Preeg William E.
Published: November 2016

Recent advances in logging-while-drilling sigma measurements include three-detector thermal-neutron and gamma-ray decay measurements with different radial sensitivities to assess the presence of invasion. We have developed an inversion-based work flow for the joint interpretation of multidetector neutron, density, and sigma logs to reduce invasion, shoulder-bed, and well-deviation effects in the estimation of porosity, water saturation, and hydrocarbon type, whenever the invasion is shallow. The procedure begins with a correction for matrix and fluid effects on neutron and density-porosity logs to estimate porosity. Multidetector time decays are then used to assess the radial length of the invasion and estimate the virgin-zone sigma while simultaneously reducing shoulder-bed and well-deviation effects. Density and neutron porosity logs are corrected for invasion and shoulder-bed effects using two-detector density and neutron measurements with the output from the time-decay (sigma) inversion. The final step invokes a nuclear solver in which corrected sigma, inverse of migration length, and density in the virgin zone are used to estimate water saturation and fluid type. The fluid type is assessed with a flash calculation and Schlumberger’s Nuclear Parameter calculation code to account for the nuclear properties of different types of hydrocarbon and water as a function of pressure, temperature, and salinity. Results indicate that accounting for invasion effects is necessary when using density and neutron logs for petrophysical interpretation beyond the calculation of total porosity. Synthetic and field examples indicate that the mitigation of invasion effects becomes important in the case of salty mud filtrate invading gas-bearing formations. The advantage of the developed inversion-based interpretation method is its ability to estimate layer-by-layer petrophysical, compositional, and fluid properties that honor multiple nuclear measurements, their tool physics, and their associated borehole geometrical and environmental effects.
Shallow diffraction imaging in an SH-wave crosshole configuration
Authors: Lellouch Ariel , Reshef Moshe
Published: November 2016

Imaging shallow subsurface voids, such as karsts, sinkholes, pinch-outs, dikes, and man-made voids, is an important task in near-surface geophysics. We have developed a new diffraction-based methodology for void detection and imaging. Due to the low signal-to-noise ratio of the diffracted signal in surface acquisition setups, we advocate the use of an SH-wave multicomponent crosshole acquisition. Naturally, the same setup can be used for velocity model building using tomography and for void imaging. The SH-wave data are migrated using a model-based, image-point-dependent automatic muting function that separates direct arrivals from diffracted events in the migration process. For the purpose of location and velocity analysis, data are migrated to the depth imaging offset domain. Only when the velocity model and imaging locations are correct will the diffracted energy be coherently focused to the void location and the diffracted event moveout in the migrated gather will be flat. We found that the received diffracted signal is clearer and has better temporal separation compared with a conventional P-wave crosshole survey. We determined the usefulness of this method using synthetic and field data examples for 2D acquisitions and a synthetic 3D case, showing that a precise imaging is possible. The importance of the S-waves velocity model, which can be extracted from the same survey using conventional tomography methods, is also discussed.
The use of seismic modeling for the geologic interpretation of deep seismic reflection data with low signal-to-noise ratios

Published: November 2016

We have performed a deep seismic reflection study, DACIA-PLAN, based on the data recorded along a crooked line across the southeastern Romanian Carpathians. The signal-to-noise ratio (S/N) of these data varies along the seismic profile, and its variation is considered to be an effect of the rough topography, complex subsurface geology, and varying surface conditions encountered during seismic data acquisition. The migrated time section that covers the mountainous area is clear, without visible reflections, making the geologic interpretation very difficult. We used a seismic modeling technique to explain the poor S/N of the recorded data and to generate synthetic seismic sections that can be useful for the geologic interpretation of the field seismic section (migrated time section). We used ray-tracing modeling to obtain the expected seismic expression of horizons of interest. Subsurface illumination modeling indicates that the complex subsurface geology and irregularly deployed sources and receivers are responsible for the incomplete and/or uneven illumination of the subsurface and can lead to strong amplitude variations. We then used 2.5D acoustic finite-difference modeling to analyze the effect of a crooked line on seismic wave propagation. The synthetic shot gathers prove that crooked line arrival times for reflected and head waves contain static time shifts relative to a straight line regular sampling geometry. Some geologic interfaces of interest are not well-imaged on the synthetic seismic section, and this is considered to be an effect of poor positioning during seismic data acquisition. We used the velocity model from the tomographic inversion of first-arrival traveltimes and synthetic and field crooked line deep seismic reflection data to create a structural image for the southeastern Romanian Carpathians and the Focsani Basin, which tie well with the geologic model built for this area on the basis of geologic and well data only.

O Estado e a distribuição da imprensa: disputas pelo controle das bancas de jornais e da regulação da categoria dos jornaleiros na Era Vargas
Authors: Chagas Viktor Henrique Carneiro de Souza
Published: November 2016

O presente artigo se propõe a discutir a relação entre imprensa e Estado sob uma perspectiva incomum, que leva em consideração o lugar do jornaleiro na cadeia produtiva dos impressos e aponta para o papel político dos sistemas de distribuição para o modelo de organização econômica da imprensa no país. Com base na experiência brasileira, é possível argumentar que raramente os jornaleiros são percebidos em toda a extensão do que representam, mas o período marcante da Era Vargas constitui um laboratório histórico exemplar para esta observação.

Published: November 2016

A comunidade de portugueses formada em Londres entre 1808 e 1822 tem excelentes representantes intelectuais: Hipólito José da Costa, Bernardo Rocha Loureiro, José Liberato e Joaquim de Freitas são os principais. Na estrutura dos jornais por eles criados, a razão às vezes se confunde com outros tipos de dispositivos de convencimento. Este texto objetiva perceber como as formas mais complexas de imaginação política descem aos níveis mais elementares de boatos e fofocas, patentes na descaracterização do adversário de forma a impugnar a sua argumentação. Noutras palavras, especular sobre como a fofoca se torna um rumor generalizado e ganha espaço na estrutura dos jornais.

Recent advances in understanding and managing urolithiasis
Authors: Strohmaier Walter L.
Published: November 2016

During the last few years, there has been relevant progress in both understanding and managing urolithiasis. Our knowledge of stone formation has changed; although the importance of urine biochemistry was questioned by several investigators years ago, the decisive role of cellular processes (induced by oxidative stress) and the renal papilla has only recently been generally accepted as the most important step in stone formation. For calcium oxalate urolithiasis, the formation of papillary calcifications plays a key role and is of prognostic relevance. Further research has to concentrate on these aspects of preventing urolithiasis. Stone prevention (metaphylaxis) is a major issue when considering the burden it places on healthcare systems. An effective metaphylaxis could lower the cost of stone therapy significantly. For uric acid urolithiasis, so far there is only preliminary information available showing that papillary plaques are not as important as they are in calcium oxalate urolithiasis. Concerning stone management, endourology has improved stone therapy significantly during the last few years. Morbidity decreased and success (stone-free) rates increased. Therefore, the indications for extracorporeal shockwave lithotripsy (ESWL) narrowed. ESWL, however, still has its place in stone therapy. There is not one single treatment modality that is equally effective for all situations. It is important to observe the differential indications for different stones depending on size, localization, and composition.
Can Novices Create Alternatives of the Same Quality as Experts?
Authors: Siebert Johannes
Published: November 2016

The quality of alternatives is crucial for making good decisions. The process of generating high-quality alternatives can be enhanced by using decision makers’ objectives as prompts. This paper examines empirically the impact and interrelation of experience and the prompting with objectives on decision makers’ ability to create alternatives for an important decision. The study confirms with high significance that both experience and prompting with objectives enhance the quality of alternatives. We are able to show that all participants, irrespective of their experience, enhance the quality of their alternatives when they are prompted with objectives; i.e., the relationship between being prompted with objectives and the quality of alternatives is not moderated by experience. In contrast to gaining experience, prompting a participant with objectives can be utilized immediately without a long learning phase and is able to substitute for experience in certain decision contexts. Furthermore, we analyze how prompting with objectives affects the creation of alternatives. We find evidence that the relation between being prompted with objectives and the quality of alternatives is partially mediated by the number of objectives considered while creating alternatives.
Solution of Monotone Complementarity and General Convex Programming Problems Using a Modified Potential Reduction Interior Point Method
Authors: Huang Kuo-Ling , Mehrotra Sanjay
Published: November 2016

We present a homogeneous algorithm equipped with a modified potential function for the monotone complementarity problem. We show that this potential function is reduced by at least a constant amount if a scaled Lipschitz condition (SLC) is satisfied. A practical algorithm based on this potential function is implemented in a software package named iOptimize. The implementation in iOptimize maintains global linear and polynomial time convergence properties, while achieving practical performance. It either successfully solves the problem, or concludes that the SLC is not satisfied. When compared with the mature software package MOSEK (barrier solver version 6.0.0.106), iOptimize solves convex quadratic programming problems, convex quadratically constrained quadratic programming problems, and general convex programming problems in fewer iterations. Moreover, several problems for which MOSEK fails are solved to optimality. We also find that iOptimize detects infeasibility more reliably than the general nonlinear solvers Ipopt (version 3.9.2) and Knitro (version 8.0).
VaR BASED RISK MANAGEMENT
Authors: Bohdalová Mária , Greguš Michal
Published: November 2016

In this paper we discuss the Value–at–Risk concept and we analyse the market risk by using EWMA approach. EWMA (exponentially weighted moving average) forecasting technique is a popular measure of various risks in financial risk management. We will compare standard EWMA, robust EWMA and skewed EWMA forecast of VaR. JP Morgan standard EWMA is derived from Gaussian distribution. Robust EWMA is based on Laplace distribution and skewed EWMA is a new approach derived from an asymmetric Laplace distribution. Asymmetric Laplace distribution takes into account both skewness and heavy tails in return distribution and the time varying nature of them in practice. Skewed EWMA VaR is a generalization of the standard EWMA method. Using these approaches we will analyse selected financial series (three European market indexes and one exchange rate). We have found andconfirmed that skewed EWMA forecasting of VaR outperforms the standard EWMA method.
FORMS OF MANAGEMENT IN AGRICULTURE IN UZBEKISTAN: SCIENTIFIC AND THEORETICAL BASIS OF ITS EFFECTIVENESS
Authors: Tadjibaeva Dilorom
Published: November 2016

During the early years of independence (1990s), agricultural and institutional changes in Uzbekistan were made based on the specific characteristics of our country. During transformation, almost nothing has changed in terms of effectivity in regards to transformation of state farms to collective farms still did not make these farms profitable. Only with the formation of dehkan farms (a form of individual farming) after 2004 did agricultural entities started becoming profitable. How can this be explained? Why are these agricultural forms of management more efficient and coincide with the mentality of our population? In this article, using the neo-institutional theory, we have discussed these questions in an attempt to answer these questions by justifying a theoretical point. This theory shows that major issue property rights and transaction costs play main role in the definition of forms of farms management. Statistical analysis of transaction costs and local specifics resulted in a conclusion that the dehkan farming form has significant advantages.
EVALUATING MEASURES OF MARKET RISK IN CIRCUMSTANCES OF GLOBAL FINANCIAL CRISIS – EMPIRICAL EVIDENCE FROM FIVE COUNTRIES
Authors: Terzić Ivica , Milojević Marko
Published: November 2016

The purpose of this paper is to evaluate performance of value-at-risk (VaR) produced by two risk models: historical simulation and Risk Metrics. We perform three backtest: unconditional coverage, independence and conditional coverage. We present results on both VaR 1% and VaR 5% on a one-day horizon for the following indices: S&P 500, DAX, SAX, PX and Belex 15. Our results show that Historical simulation 500 days rolling window approach satisfies unconditional coverage for all tested indices, while Risk Metrics has many rejection cases. On the other hand Risk Metrics model satisfies independence backtest for three indices, while Historical simulation has rejected more times. Based on our strong criteria to accept accuracy of VaR models only if both unconditional coverage and independence properties are satisfied, results indicate that during the crisis period all tested VaR models underestimate the true level of market risk exposure.

THE IDEA OF ONE WAY WORD FORMATION DICTIONARY
Authors: Kovyneva Irina
Published: November 2016

In the modern word formative theory of neologisms there is practically no description of concrete unusual occasional way of word formation, such as holophrasis, gendiadis, decomposition and others. There is also no dictionary, describing one of these types of word composition. There are two specific questions, which occur with the process of сreation of one way word formation (holophrase) dictionary: 1) how to introduce the holophrastic construction (HC) into the dictionary; 2) the context of usage of HC. Though HC is polycomponental, the introduction should be only one – by the first word in the construction. The context of usage of HC is usually limited by the sentence, in which HC is used. The HC dictionary emphasizes the new opening in the philosophic understanding of the sense of meaning and its connection with the lexicographic semantisation.

DOES THE UPPSALA INTERNATIONALIZATION MODEL EXPLAIN THE INTERNATIONALIZATION PROCESS OF PROFESSIONAL BUSINESS SERVICE FIRMS?
Authors: Górska Magda
Published: November 2016

The aim of this contribution is to verify if the Uppsala Model with later variations introduced by the authors is the right framework to explain internationalization process of Professional Business Service Firms (PBSFs). The focus is placed on the entry of one type of PBSFs, namely advertising agencies into the Chinese market. The example is based on a case study. This paper deliberates about identified factors in the internationalization process of advertising agencies that fit to the Uppsala model and about factors that deviate from it. Several stages are identified in the entrance of advertising agencies into the Chinese market. These are as follows: initial stage - external agent, participation stage - representative office, establishment stage - joint venture, network expansion stage – branch offices and other joint ventures. The presence of stages suggests that the Uppsala model may prove useful in explanation of foreign entry strategies in PBSFs in general. In addition to that, support is also found for market entry due to networking activities. Client following was identified as most common entry mode in the studied group of PBSFs.

Metabolismo líquido da matéria orgânica, calcificação e fluxos de dióxido de carbono em dois recifes costeiros sujeitos a diferentes graus de impacto: Coroa Vermelha e Taipus de Fora, Bahia
Authors: Souza Marcelo Friederichs Landim de , Santana Thaís Bomfim
Published: November 2016

This study intended to compare physical and chemical variables, net ecosystem metabolism (production – respiration) and calcification-carbonate dissolution rates in two coastal reefs subject to different levels of anthropogenic inputs of nutrients and organic matter. The coast surrounding Coroa Vermelha reef presented a higher degree of urbanization and touristic activities than Taipus de Fora at the time of sampling. The temperature, dissolved inorganic nutrients, total alkalinity, and total suspended solids were significantly higher in Coroa Vermelha reef, probably as a result of the anthropogenic inputs. These variables in Taipus de Fora were comparable to those found in the literature for Recife de Fora, an offshore protected reef and other less impacted reefs.  Total alkalinity, dissolved inorganic carbon and carbon dioxide partial pressure were lower and pH was higher in the reef flat than at the surrounding seawater. There was a prevalence of an influx of atmospheric carbon dioxide to reef water, net autotrophy and calcification. A significant correlation was observed between net calcification and net community metabolism. The benthic photosynthesis in the reef flat during low tide decreases the carbon dioxide partial pressure and increases the aragonite saturation state, establishing thermodynamic conditions that favor calcification.
On the Removal of Steganographic Content from Images

Steganography is primarily used for the covert transmission of information even though the purpose can be legitimate or malicious. The primary purpose of this work is to build a firewall which will thwart this transmission. This will be achieved by radiometric and geometric operations. These operations will degrade the quality of cover image. However these can be restored to some extent by a deconvolution operation. The finally deconvolved image is subjected to steganalysis to verify the absence of stego content. Experimental results showed that PSNR and SSIM values are between 35 dB - 45 dB and 0.96, respectively which are above the acceptable range. Our method can suppress the stego content to large extent irrespective of embedding algorithm in spatial and transform domain. We verified by using RS steganalysis, difference image histogram and chi-square attack, that 95 per cent of the stego content embedded in the spatial domain was removed by our showering techniques. We also verified that 100 per cent of the stego content was removed in the transform domain with PSNR 30 dB - 45 dB and SSIM between 0.67-0.99. Percentage of stego removed in both domains was measured by using bit error rate and first order Markov feature.
Multiplicative Error State Kalman Filter vs Nonlinear Complimentary Filter for a High Performance Aircraft Attitude Estimation
Authors: C. Kamali , Jain Shikha
Published: November 2016

Modern control law designs increasingly use aircraft attitude information to improve aircraft manoeuverability. Attitude information allows for gravity term compensations in the longitudinal as well as lateral directional control laws of a typical fighter aircraft. Methodologies and comparisons of multiplicative error state Kalman filter (MEKF) and nonlinear complimentary filter for estimation of attitudes of a high performance aircraft using its onboard autonomous sensors is presented. Shows a problem in pitch angle estimation beyond ± 80 deg in the MEKF and a solution is proposed for the same for the first time. Also presents novel aiding sensor modelling for the implementation of attitude heading reference system for this class of aircraft for the first time. The filter formulations are evaluated using full range manuoevering real flight test data.
Aerodynamic Characterisation of Ramjet Missile through Combined External-internal Computational Fluid Dynamics Simulation

Published: November 2016

Combined external-internal flow simulation is required for the estimation of aerodynamic forces and moments of high speed air-breathing vehicle design. A wingless, X-tail configuration with asymmetrically placed rectangular air intake is numerically explored for which experimental data is available for different angles of attack. The asymmetrically placed air intakes and protrusions make the flow field highly three-dimensional and existing empirical relations are inadequate for preliminary design. Three dimensional Navier Stokes equations along with SST-kω turbulence model were solved with a commercial CFD solver to analyse the combined external and internal flow field of the configuration at different angles of attack. Estimated aerodynamic coefficients match well with experimental data and estimated drag coefficient are within 8.5 per cent of experimental data. Intake performance parameters were also evaluated for different angles of attack.
Agonía y revitalización de una lengua y un pueblo: los Nonuya del Amazonas
Authors: Echeverri Juan Álvaro , Romero Cruz Isabel Victoria
Published: November 2016

El nonuya es una de las tres lenguas sobrevivientes de la familia lingüística witoto, que también incluye el uitoto y el ocaina. Los nonuya fueron un pueblo numeroso, casi exterminado durante el período cauchero a principios del siglo xx. Otros grupos vecinos lograron retornar a su territorio ancestral después del éxodo cauchero. Solo dos hombres nonuya retornaron y se casaron con mujeres de otros grupos. Sus descendientes (cerca de 100 personas) perdieron su lengua paterna y adoptaron la lengua de otros grupos (muinane y andoque). Desde 1992, este grupo decidió reafirmar su identidad y formó una nueva comunidad. Este artículo presenta un breve recuento de la historia de este pueblo, muestra los avances en la documentación de su lengua y analiza algunos aspectos sociolingüísticos del proceso de revitalización lingüística en el contexto de las otras lenguas habladas en la comunidad. Además, discute la relación del nonuya con las otras dos lenguas de la familia witoto y presenta algunos resultados preliminares de su fonología y morfología, a partir del corpus documentado.

Fincas cafetaleras de la “Costa Cuca” en Guatemala. Patrimonio cultural desvalorizado
Authors: Quiñónez Guzmán Javier
Published: November 2016

Resumen Tomando como referencia dos casos de estudio ubicados en la región de la “Costa Cuca”, al Sur Occidente del país, se da a conocer la importancia que tienen las fincas cafetaleras para Guatemala y las calidades que poseen para ser consideradas como Patrimonio Cultural de la Nación, debido a su valoración tangible. Para ello se revisa rápidamente el contexto general del inicio de la producción de café en el país, las características de la región estudiada y el recorrido realizado a las fincas cafetaleras mencionadas. Además, con el análisis de la legislación nacional guatemalteca sobre el tema de patrimonio cultural, se logra evidenciar el valor patrimonial cultural de las fincas cafetaleras para Guatemala, su estado actual de conservación y la necesidad de revitalización en función del desarrollo sostenible del área de estudio y del país.Abstract The importance of the existence of coffee plantation estates (architectural complexes) located in the southwest region of Guatemala, known as “Costa Cuca” and the qualities and values they possess, should be considered as cultural heritage. This importance is demonstrated by the analysis of the two case studies presented in this article. To accomplish this purpose and to successfully argue that these complexes should be elevated to cultural heritage of our country, maintain their current condition of conservation and, in fact, be preserved and revitalized, the analysis includes a quick revision of the general context of the production of coffee in its early years, facts about the characteristics of the proposed region, the results of visits to these complexes and a profound revision of the current legislation in terms of cultural heritage in our country.
The effects of text editing and subtitle presentation rate on the comprehension and reading patterns of interlingual and intralingual subtitles among deaf, hard of hearing and hearing viewers

Published: November 2016

In this paper we examine the influence of text editing (edited vs. verbatim subtitles) and subtitle presentation rates (12 vs. 15 characters per second) on the comprehension and reading patterns of interlingual and intralingual subtitles among a group of 44 deaf, 33 hard of hearing and 60 hearing Polish adult subjects. The results of the eyetracking study show no benefit of editing down the text of subtitles, particularly in the case of intralingual subtitling and deaf viewers. Verbatim subtitles displayed with the higher presentation rate yielded slightly better comprehension results, were skipped less often, and resulted in more effective reading patterns. Deaf and hard of hearing participants had lower comprehension than hearing people; they also had a higher number of fixations per subtitle and were found to dwell on subtitles longer than the hearing.
