An Effective XML Storage Method Based on Deleting XPath Query Minimization

The storage method for XML data in database will affect the efficiency of XML keywords querying, indexing and updating significantly. In most cases, the XPath sentences provided by user are not refined. These queries can often achieve minimization by deleting redundant parts. It means the minimized query is one of subsets of this query. Such kind of minimization query is method based on deleting queries. The steps are determining nodes relations, finding redundant nodes, deleting redundant nodes and sub-tree and obtain final minimization query tree. In this paper, we propose an improved XPath query minimization method based on deletion using simulation concept. Experiments analysis results show that with introduction of appropriate indexing and new algorithm, the XML keywords indexing efficiency can be significantly improved.
The Discovery Outburst of the X-Ray Transient IGR J17497–2821 Observed with RXTE and ATCA

We report the results of a series of RXTE and ATCA observations of the recently discovered X-ray transient IGR J17497-2821. Our 3-200 keV PCA+HEXTE spectral analysis shows very little variations over a period of ~10 days around the maximum of the outburst. IGR J17497-2821 is found in a typical low-hard state (LHS) of X-ray binaries (XRBs), well represented by an absorbed Comptonized spectrum with an iron edge at about 7 keV. The high value of the absorption (~4 × 1022 cm-2) suggests that the source is located at a large distance, either close to the Galactic center or beyond. The timing analysis shows no particular features, while the shape of the power density spectra is also typical of the LHS of XRBs, with ~36% rms variability. No radio counterpart is found down to a limit of 0.21 mJy at 4.80 and 8.64 GHz. Although the position of IGR J17497-2821 in the radio to X-ray flux diagram is well below the correlation usually observed in the LHS of black holes, the comparison of its X-ray properties with those of other sources leads us to suggest that it is a black hole candidate.
Image Fusion Based on Curvelet Transform and Principal Component Analysis

For the fusion of infrared and visible images, the curvelet transform was performed on the two source images to obtain the transform coefficients on different scales and various directions. For low frequency coefficients, the weighted average method is adopted. For high frequency coefficients, in order to ensure more useful information retained and fewer errors reduced, the adaptive weighted algorithm feature product was adopted in this paper. And the fusion image was obtained through the inverse curvelet transform. The first principal component can be reconstructed according to the fusion image. The fused components and other components are performed together by the inverse PCA transform to obtain the final fusion image. The final reconstructed to obtain the fusion result. The fusion image obtained is evaluated in subjective and objective factors. Experiment results show that the algorithm has a better fusion result from the perspective of either subjective visual effect or objective statistical data.
Corrosion detection system

A system (1) for detecting and locating corrosion on the outer surface of a metal body (2). The system includes an extended electromagnetic waveguide (6) arranged adjacent to the outer surface of themetal body. The electromagnetic waveguide includes a sacrificial component that experiences substantially the same environment as the outer surface of the metal body. The system also includes a waveform generator (10) arranged to be connected to the waveguide and to inject an electromagnetic waveform into the waveguide. The system also includes a waveform analyser (12) connected to the waveguide.The waveform analyser is arranged to receive a reflected portion of the injected electromagnetic waveform from the waveguide. The reflected portion of the injected electromagnetic waveform is used bythe waveform analyser to determine the location of corrosion of the sacrificial component of the waveguide.
Biological effects of a software-controlled voltage pulse generator (PhyBack PBK-2C) on the release of vascular endothelial growth factor (VEGF).

BACKGROUND Electrical stimulation (ES) may induce vascular permeability and physiological angiogenesis. ES of rat muscles significantly increases the microvessel density and vascular endothelial growth factor (VEGF) protein levels. Thus, a pilot study was designed to analyze the effects of low-voltage electric impulses on VEGF levels in patients with dystrophic ulcers. MATERIALS AND METHODS Circulating VEGF levels were analyzed in 9 patients undergoing an ES session with low voltage software-controlled impulses applied through topical transducers (1-9 micros width, 1-420-Hz frequency and 30-120 V strength-100 microA max). RESULTS The session was accompanied by a peak of circulating VEGF (3-10 min from start) in all 9 patients, which was preceded by a rise of TNF-alpha (2-min) and was independently associated with soluble E-selectin levels. Nitric oxide generation was significantly improved on the day after treatment. No hemostatic activation or sustained inflammatory reaction were observed. CONCLUSION ES may represent a safe method for augmenting VEGF-mediated vascular protection, either directly or by induction of NO.
CAN TRANSITION DYNAMICS EXPLAIN THE INTERNATIONAL OUTPUT DATA?

This paper studies the transition dynamics predictions of an R&D-based growth model, and evaluates their performance in explaining income disparities across nations. We find that the fraction of the observed cross-country income variation explained by the transitional dynamics of the model is as large as the one accounted for by existing steady-state level regressions. Our results suggest that the traditional view of a world in which nations move along their distinct balanced-growth paths is as likely as the one in which countries move along adjustment paths toward a common (very long run) steady state.
Factor Analysis and the Social Capital Index: A Study at the Brazil / Bolivia Border

Objective: The study aimed to build the level of social capital by neighborhoods Guajara-Mirim border region between the State of Rondonia, Brazil and the Republic of Bolivia, which in recent years has been showing signs of social fragility due advance not virtuous practices. Method: This work made use of research in secondary bases as well as in primary bases. The tabulation of qualitative and quantitative data was performed in Excel (2010) and for their processing performance index construction purposes were calculated following the factorial analysis techniques presented by Hair et al. [19] Santana [20, 21]; and Choi [22]. For this, we made use of the statistical tool SPSS (Statistical Package for Social Sciences) for the construction of the indices of social capital. The correlation analysis process was done in Excel. results: It was observed that the capital reached regular levels in Guajara-Mirim neighborhoods not observable, so correlations between the studied parameters, however, it needs to be further studied as factors such as the flooding of the Mamore river may have interfered in any way in the implementation process of the field survey to the residents of the city. It became clear that the municipality of Guajara-Mirim suffers from serious social problems and that most problems are correlated with the increase in alcoholic beverage market in the city and use drugs. However, was not observed as the institutional arrangements are dealing with this problem, that is, as public bodies are relating to discuss actions for concrete solutions to this evil that plagues large portion of the population of Guajara-Mirim, mainly young teenagers residents of Guaja-Mamim. However, we hope to continue this work in order to better understand this mechanism of social network between the actors of this process in the region.
Measurement and Characterization of Helicopter Noise in Steady-State and Maneuvering Flight

A special acoustic flight test program was performed on the Bell 206B helicopter outfitted with an in-flight microphone boom/array attached to the helicopter while simultaneous acoustic measurements were made using a linear ground array of microphones arranged to be perpendicular to the flight path. Air and ground noise measurements were made in steady-state longitudinal and steady turning flight, and during selected dynamic maneuvers. Special instrumentation, including direct measurement of the helicopter s longitudinal tip-path-plane (TPP) angle, Differential Global Positioning System (DGPS) and Inertial Navigation Unit (INU) measurements, and a pursuit guidance display were used to measure important noise controlling parameters and to make the task of flying precise operating conditions and flight track easier for the pilot. Special care was also made to test only in very low winds. The resulting acoustic data is of relatively high quality and shows the value of carefully monitoring and controlling the helicopter s performance state. This paper has shown experimentally, that microphones close to the helicopter can be used to estimate the specific noise sources that radiate to the far field, if the microphones are positioned correctly relative to the noise source. Directivity patterns for steady, turning flight were also developed, for the first time, and connected to the turning performance of the helicopter. Some of the acoustic benefits of combining normally separated flight segments (i.e. an accelerated segment and a descending segment) were also demonstrated.
1 2 Ju l 2 01 4 Geometric chained inequalities for higher-dimensional systems

For systems of an arbitrary dimension, a theory of geometric chained Bell inequalities is presented. The approach is based on chained inequalities derived by Pykacz and Santos. For maximally entangled states the inequalities lead to a complete 0 = 1 contradiction with quantum predictions. Local realism suggests that the probability for the two observes to have identical results is 1 (that is, a perfect correlation is predicted), whereas quantum formalism gives an opposite prediction: the local results always differ. This is so for any dimension. We also show that with the inequalities, one can have a version of Bell’s theorem which involves only correlations arbitrarily close to perfect ones.
Recognition of Affect, Judgment, and Appreciation in Text

The main task we address in our research is classification of text using fine-grained attitude labels. The developed @AM system relies on the compositionality principle and a novel approach based on the rules elaborated for semantically distinct verb classes. The evaluation of our method on 1000 sentences, that describe personal experiences, showed promising results: average accuracy on the fine-grained level (14 labels) was 62%, on the middle level (7 labels) - 71%, and on the top level (3 labels) - 88%.
The hapticon editor: a tool in support of haptic communication research

We define haptic icons, or "hapticons", as brief programmed forces applied to a user through a haptic interface, with the role of communicating a simple idea in manner similar to visual or auditory icons. In this paper we present the design and implementation of an innovative software tool and graphical interface for the creation and editing of hapticons. The tool's features include various methods for creating new icons including direct recording of manual trajectories and creation from a choice of basis waveforms; novel direct-manipulation icon editing mechanisms, integrated playback and convenient storage of icons to file. We discuss some ways in which the tool has aided our research in the area of haptic iconography and present an innovative approach for generating and rendering simple textures on a low degree of freedom haptic device using what we call terrain display.
Grasping microscopic objects by an optical trapping system controlled by five finger tips

There are increased needs for manipulating microscopic objects. One of enabling technologies is an instrument called optical tweezers (OT) that uses a focused laser beam to trap and move microscopic objects. OT has been shown effective for directly manipulating spherical, cylindrical or axis-symmetrical shapes. For other forms of shapes that do not show any symmetry, there have been works on using micrometer sized balls as a handle to indirectly manipulate the objects. Direct manipulation is difficult because complex trapping potential needs to be calculated to stably trap non-symmetrical shapes. User interfaces for these "indirect" systems use a computer mouse to design a layout of balls for surrounding (holding) an object and a trajectory that describes how these balls as a whole moves. The contained object pushed by these surrounding balls then moves accordingly. In this study, we introduce an intuitive user interface system for manipulating these balls. Using virtual reality gloves, each finger tip position of an operator is used to position control these balls. This user interface system enables the operator to intuitively grasp, move and release irregular formed shapes.
Seasonal Shift in Climatic Limiting Factors on Tree Transpiration: Evidence from Sap Flow Observations at Alpine Treelines in Southeast Tibet

Alpine and northern treelines are primarily controlled by low temperatures. However, little is known about the impact of low soil temperature on tree transpiration at treelines. We aim to test the hypothesis that in cold-limited forests, the main limiting factors for tree transpiration switch from low soil temperature before summer solstice to atmospheric evaporative demand after summer solstice, which generally results in low transpiration in the early growing season. Sap flow, meteorological factors and predawn needle water potential were continuously monitored throughout one growing season across Smith fir (Abies georgei var. smithii) and juniper (Juniperus saltuaria) treelines in southeast Tibet. Sap flow started in early May and corresponded to a threshold mean air-temperature of 0°C. Across tree species, transpiration was mainly limited by low soil temperature prior to the summer solstice but by vapor pressure deficit and solar radiation post-summer solstice, which was further confirmed on a daily scale. As a result, tree transpiration for both tree species was significantly reduced in the pre-summer solstice period as compared to post-summer solstice, resulting in a lower predawn needle water potential for Smith fir trees in the early growing season. Our data supported the hypothesis, suggesting that tree transpiration mainly responds to soil temperature variations in the early growing season. The results are important for understanding the hydrological response of cold-limited forest ecosystems to climate change.

Accelerating CBIR System using Graphics Processing Unit in OPEN CV Environment

Content Based Image Retrieval is a system for retrieving the images from a dataset of images. The CBIR has several stages including feature extraction at the initial level and then performing the similarity matching. Later on based upon the similarity matching results the required images can be extracted. Images are a complex data to handle as they are composed of matrices and vectors of data and also due to multi thread execution of algorithms, programmability and low cost, image processing becomes an appropriate field of achieving parallelism. To parallelize the phases of CBIR a special hardware is used known as Graphics Processing Unit. The objectives of the published work is to develop a Content Based Image Retrieval system and test it on benchmark WANG database using suitable and efficient techniques so as to achieve efficient results. As images are complex and there is an approach of achieving parallelism while dealing with images, so after implementing CBIR, the feature extraction phase has been parallelized and the tendency of GPU processor is exploited to obtain the speed up. An accuracy of range between 22 to 67% for individual categories of the databasewas achieved. Finally on comparing the execution times of serial implementation and parallel implementation a considerable speed up of 15 % on an average was obtained.
Gold Standard for Expert Ranking: A Survey on the XWiki Dataset

We are designing an automated technique to find and recommend experts for helping in Requirements Engineering tasks, which can be done by ranking the available people by level of expertise. For evaluating the correctness of the rankings produced by the automated technique, we want to compare them to a gold standard. In this work, we ask external people to look at a set of discussions and to rank their participants, before to evaluate the reliability of these rankings to serve as a gold standard. We describe the setting and running of this survey, the method used to build the gold standard from the rankings of the subjects, and the analysis of the results to obtain and validate this gold standard. Through the analysis of the results, we conclude that we obtained a reasonable gold standard although we lack evidences to support its total correctness. We also made the interesting observation that the most reliable subjects build the least ordered rankings (i.e. has few ranks with several people per rank), which goes against the usual assumptions of Information Retrieval measures.
Production process dependence of neutrino flavor conversion

We perform a covariant wave-packet analysis of neutrino oscillations taking into account the lifetime of the neutrino production process . We find that flavor oscillations in space are washed out when the neutrinos are produced from long lived resonances - and what may be observed in appearance/disappearance experiments is a uniform conversion probability independent of distance. The lifetime of the resonance which produces the neutrinos acts as the the effective baseline of the experiment. For this reason the LSND experiment where neutrinos are produced from muon decay has two orders of magnitude more sensitivity to neutrino mass square difference than other experiments where the neutrinos are produced from pion or kaon decays.
Effects of Video-based e-Learning on EFLAchievement : The Mediation Effect of Behavior Control Strategies

The current study aimed to investigate whether video-based e-learning (i.e., the Educational Broadcasting Service (EBS)) influences the achievement of Korean high school students (years 2-3) in English as a foreign language (EFL) through the mediation of their use of behavior control strategies. The study used data from the 2010 and 2011 Korean Education Longitudinal Study of 2,309 students. Structural equation modeling was used to analyze whether the behavior control strategies mediated consistent use of EBS with high school students and whether video-based e-learning led to an increase or a decrease in the students’ EFL achievement test scores. In general, consistent EBS use resulted in changes in the high school students’ EFL achievement test results with the mediation of the behavior control strategies. However, a decrease model showed slightly better model-data fit than an increase model because in the decrease model the time management and resource use strategies had a significant negative relationship to decreases in the EFL test scores between year 2 and year 3. As a significant function of time management, EBS use seemed to work in preventing decreases in EFL achievement.
Mannanoligosaccharide agglutination by Salmonella enterica strains isolated from carrier pigs

Type-1 fimbriae are associated with most Salmonella enterica serovars and are an essential factor for host colonization. Mannanoligosaccharides (MOS), a prebiotic that is agglutinated by type-1 fimbriae, are proposed for the control of enterobacteria colonization and may be an alternative to Salmonella control in pigs. The aim of this study was to evaluate the capability of porcine Salmonella strains to adhere to MOS in vitro. A total of 108 strains of Salmonella sp. isolated from carrier pigs were evaluated for the amplification of fimA and fimH genes, agglutination of MOS and hemagglutination. In all tested strains, amplicons of expected size were detected for both fimA and fimH gene. In the hemagglutination assays, 31 (28.7%) strains presented mannose–sensitive agglutination of erythrocytes, indicating that the strains were expressing type-1 fimbriae. Considering only strains expressing the type-1 fimbriae, 23 (74.2%) presented a strong agglutination of MOS, 3 (9.6%) a weak reaction and 5 (16.2%) none. The results indicate that Salmonella enterica strains expressing type-1 fimbriae can agglutinate effectively in vitro to MOS.
Security analysis for biometric data in ID documents

In this paper we analyze chances and challenges with respect to the security of using biometrics in ID documents. We identify goals for ID documents, set by national and international authorities, and discuss the degree of security, which is obtainable with the inclusion of biometric into documents like passports. Starting from classical techniques for manual authentication of ID card holders, we expand our view towards automatic methods based on biometrics. We do so by reviewing different human biometric attributes by modality, as well as by discussing possible techniques for storing and handling the particular biometric data on the document. Further, we explore possible vulnerabilities of potential biometric passport systems. Based on the findings of that discussion we will expand upon two exemplary approaches for including digital biometric data in the context of ID documents and present potential risks attack scenarios along with technical aspects such as capacity and robustness.
