DETECTION OF CLICKS USING SINUSOIDAL MODELING FOR THE CONFIRMATION OF THE CLICKS

ABSTRACT This article presents methods for clicks detection in degraded audio recordings. It begins with a brief description of the method implemented in first instance for the detection of clicks in audio sources based on linear prediction. Looking for an improvement of the results obtained with this method, we propose a method based on sinusoidal modeling for the confirmation of the clicks. This method discards clicks that were wrongly detected. This allows the detection of clicks of small amplitude avoiding wrong detections. The results obtained by this method are shown, confirming the good operation. Finally, the method implemented for detection of clicks in naturally degraded audio sources is presented. 1. INTRODUCTION There are several distinct types of degradation common in audio sources. These can be broadly classified into two groups: localized degradations and global degradations. Localized degradations are discontinuities in the waveform, which affect only certain samples. The most common of this type of degradation are the clicks. Global degradations affect all samples of the waveform being hiss the most common. The first step in the restoration of an audio source is the detec-tion of the clicks. The algorithm to be implemented must fulfill the following requirements: detect most true clicks, detect properly the width of the clicks and avoid false detections that would degrade the signal even more. The detection methods are based on linear predictors.
No evidence for an Eddington-ratio dependence of X-ray weakness in BALQSOs

Several works have studied the relation between X-ray, UV, and wind properties in broad absorption line quasars (BALQSOs), generally concluding that the formation of strong winds is tightly connected with the suppression of the ionizing EUV/X-ray emission. The Eddington ratio ($\lambda_{Edd}$), which measures the accretion rate, is also known to be related with outflow and emission-line properties in the general quasar population. Moreover, models describing quasar accretion depend on $\lambda_{Edd}$, which can thus possibly affect the relative production of accelerating UV and ionizing EUV/X-ray radiation. In this work, for the first time, we investigated whether BALQSO X-ray properties are related with the Eddington ratio. We selected a sample of 30 BALQSOs with accurate measurements of black-hole mass and BAL properties from the literature, and we complemented it with 4 additional BALQSOs we observed with \xmm\, to populate the low and high Eddington-ratio regimes. We did not find evidence for a strong relation between $\lambda_{Edd}$ and X-ray suppression, which however shows a significant correlation with the strength of the UV absorption features. These findings are confirmed also by considering a sample of mini-BALQSOs collected from the literature.
Legal Modificatory Provisions and Thematic Relations

This paper describes a system for the semantic annotation of legal texts. In particular, it deals with “modificatory provisions”, i.e. instructions, present in a legal text, to modify previous laws, by inserting, deleting or replacing parts of the older text. The paper also reports the results on a preliminary study about the use of thematic relations in marking the role of the relevant components of the modificatory provision under analysis.
Analysis between financial leverage with the stock price and the operational performance of the accepted companies in Tehran's stock market

In this study, the relationships between the changes of the economic leverage and the op erational performance of the accepted compa nies of Tehran’s stock market were analyzed. The main goal of this study is to determine if there is a meaningful relationship between the changes of the economic leverage and the operational per formance of the accepted companies of Tehran’s stock market. For this purpose, 145 companies from 2005 to 2006 with systematic elimination method were selected. The results indicated that there was a meaningful relationship between the economic leverage and the stock price. The re sults showed that an increase in the debt led to an increase in the relationship between the eco nomic leverage and the stock price. Also, the study showed that the relationship between the economic leverage and the stock price is a mean ingful and negative relationship. Finally, the study indicated the change of the economic leverage and the ratio of expenses to property is a negative and meaningful relationship.
Breakup of Droplets in Micro and Nanofluidic T-Junctions

We employ numerical simulations to investigate the breakup of droplets in micro-and nanoscale T junctions which are used to produce small droplets from a large droplet. A Volume Of Fluid (VOF) method was used and for verifying the accuracy of simulation the results compared with two analytical researches. Our results reveal that breakup time and breakup length of the droplets play important roles in handling these systems optimally. Our results also indicate that for nanoscale T-junctions by increasing the capillary number the performance increases while for the micro-scale systems there is a specific capillary number for which the system is in its optimum condition.
IRAS 05358+3543: Multiple outflows at the earliest stages of massive star formation

We present a high-angular-resolution molecular line and millimeter continuum study of the massive star formation site IRAS 05358+3543. Observations with the Plateau de Bure Interferometer in CO 1{0, SiO 2{1 and H 13 CO + 1{0 reveal at least three outflows which cannot be separated in single-dish data. Observations at millimeter and sub-millimeter wavelengths from the IRAM 30 m telescope and the CSO provide additional information on the region. The most remarkable feature is a highly collimated (collimation factor 10) and massive (>10 M) bipolar outflow of 1 pc length, which is part of a quadrupolar outflow system. The three observed molecular outflows forming the IRAS 05358+3543 outflow system resemble, in structure and collimation, those typical of low-mass star-forming regions. They might therefore, just like low-mass outflows, be explained by shock entrainment models of jets. We estimate a mass accretion rate of10 4 M/yr, sucient to overcome the radiative pressure of the central object and to build up a massive star, lending further support to the hypothesis that massive star formation occurs similarly to low-mass star formation, only with higher accretion rates and energetics. In the millimeter continuum, we nd three sources near the center of the quadrupolar outflow, each with a mass of 75{100 M. These cores are associated with a complex region of infrared reflection nebulosities and their embedded illuminating sources. The molecular line data show that SiO is found mostly in the outflows, whereas H 13 CO + traces core-like structures, though likely with varying relative abundances. Thermal CH3OH comprises both features and can be disentangled into a core-tracing component at the line center, and wing emission following the outflows. A CO line-ratio study (using data of the J = 1{0, 2{1 and 6{5 transitions) reveals local temperature gradients.
Dependence and sensitivity on the aerothermochemical model of atmospheric reentry trajectories

Several numerical analyses have been conducted to examine the effects of some state-of-the-art chemistry models on the aerothermodynamic performances of hypervelocity blunt vehicles. At the beginning, the reentry flight scenario has been defined, and the aeroheating environment has been analyzed, for the achievement of a realistic representation of the flight trajectory for a preliminary estimation of real gas effects. After the definition of the freestream conditions in which the peak heating occurs, several set of reactions have been analyzed in numerical computations. In this way, it has been possible to carry out a dispersion analysis, due to the aerothermochemical model, of the vehicle flight scenario. In detail, it has been analyzed the influence of the technique for the aerodynamic database definition (engineering, panel, and viscous computations methods) on remarkable parameters like peak heating, thermal load, crossrange, and downrange. Then, the analysis of different kind of reactions allows to investigate the reaction mechanism and to understand the main dissociation reactions occurring in high energy flows.
A Distinctive Scheme for Extraction of Symmetrical Components along with Harmonics

Symmetrical components are very excellent tools for the analysis of three phase unbalanced power system. In this paper, a software program has been developed in C++ Builder to extract the positive, negative components along with harmonics from the three phase current of a simulated three phase system. This software is user defined. The developed software has been tested on simulated system under balanced, unbalanced, faults and harmonics condition and a satisfactory result have been found.
A Structural Equation Modeling Approach to Investigate Negative Word of Mouth Impact on Customer-Based Brand Equity: Does Attribution Matter?

There is a shortage in the research which addresses the relationship between negative word of mouth (WOM) communication and customer-based brand equity dilution. This research utilizes attribution theory to demonstrate the negative word-of-mouth impact on the customer-based brand equity. Structural equation modeling was used to investigate the proposed effect of negative WOM on brand equity. The study sample consists of 71 post-graduate students, the object of negative WOM was laptops which considered a highly involvement product. Experimental investigation results reveal that customer exposure to negative word-of-mouth increases the brand equity dilution. Results were discussed in the light of casual attribution theory, and practical implications were provided.
Carbon, Nitrogen and Phosphorus Stoichiometry in Differently Aged Lucerne Stands during Flowering

This study aimed to test the hypothesis that stoichiometric ratios of C, N and P change with plant growth during flowering. The C: N, C: P and N: P varied without solid trends during flowering. The C: N was significantly different only between cuts, while the C: P and N: P were influenced by age, cut and their interaction. The C: N and C: P were higher in the 1st cut than in the 2nd cut, while for N: P, it was opposite. No solid trends were observed with the effects of age on both C: P and N: P. The N and P were closely correlated with C: N, C: P and N: P. Conclusively, stoichiometric ratios of C, N and P varied during flowering and changed with stand age and cut.
Communication Privacy Disclosure Management: An Empirical study of socialization support in a Pseudo-Online Course

This study investigated the boundaries of online learners' information disclosure, relationship building, interpersonal integration, and motivation by drawing upon the theoretical frameworks of the social information processing and communication privacy management theories and the hyperpersonal model. A total of 103 students from a higher education institution participated in the study. Results indicated that participants were willing to share their social information with others, but in varying degrees depending on the audiences, indicating that they were balancing privacy and disclosure as described in the communication privacy management theory. It was also witnessed that participants not only concealed sensitive information, but also in some cases fabricated them as explained in the hyperpersonal Model. The use of the experimental communication privacy and disclosure management system, however, did not affect participants’ interpersonal integration and motivation, thus it failed to support the social information processing theory. Overall, considering the fact that today’s students are conscious about their social information disclosure and are willing to share information, a systematic approach to social information sharing that will facilitate online learning communities is recommended. With advancements in Internet technology such as online blogging, instant messaging,
Comparison of EKF and UKF on Training the Artificial Neural Network

The Unscented Kalman Filter is known to outperform the Extended Kalman Filter for the nonlinear state estimation with a significance advantage that it does not require the computation of Jacobian but EKF has a competitive advantage to the UKF on the performance time. We compare both algorithms on training the artificial neural network. The validation data set is used to estimate parameters which are supposed to result in better fitting for the test data set. Experimental results are presented which indicate the performance of both algorithms.
Biological Network Analysis of Genes Involve in Embryogenesis of Oil Palm using ClueGO

The application of DNA sequencing technologies has a major impact on molecular biology, especially in understanding genes interaction in a certain condition. Due to a large number of genes produced by this high-throughput technology, a proper analysis tool is needed for data interpretation. ClueGO is a bioinformatics tool, an easy to use Cytoscape plug-in that strongly improves biological function interpretation of genes. It analyzes a cluster or comparing two clusters and comprehensively visualizes their group functions. This tool is applied to identify biological networks of genes involved in embryogenesis of oil palm, the most critical phase in oil palm tissue culture process. Two ESTs sequencing data from the GenBank database under accession number EY396120-EY413718 and DW247764-DW248770 were used in this study. Fifty-two and one hundred eight groups of genes were identified using biological process in Gene Ontology setting from the database of EY396120-EY413718 and DW247764-DW248770, respectively. Thirty-one groups of genes were consistently occurred in both ESTs. According to the literature, these genes play an important role in cell formations and developments, stresses and stimulus responses, photosynthesis and metabolic processes that indicate the involvement of these groups of genes in oil palm embryogenesis processes. ClueGO is the appropriate tool to analyze a large data set of genes in a specific condition, such as embryogenesis of oil palm.

Patient stress and satisfaction when allowed the presence of an accompanying person during endoscopy

Introduction: Patients undergoing esophagogastroduodenoscopy (EGD) have variable stress and anxiety and therefore commonly receive medications as sedative-anxiolytics. These medications have small but significant risks. To possibly make procedures safer and to increase patient satisfaction, this study aimed to measure the effects of allowing an accompanying person (AP) to be present in the endoscopy suite during EGD. Patients and Methods: Forty-two patients were randomly divided into two groups who would either be or not be offered to have an AP during endoscopy. Spielberger’s well-validated state and trait anxiety evaluations were administered to patients before and after EGD. APs also completed questionnaires as to their reactions after EGD. Results: 84.2% of the patients after EGD recommended accompaniment. Patients who underwent EGD with an AP tended (p < 0.06) to have decreased measurable anxiety compared to patients who were not offered an AP. The benefit was significant for persons with higher levels of anxiety prior to EGD (p < 0.04). Patients undergoing EGD for the first time had significantly more anxiety than those with previous EGD experience (p < 0.034). There was no significant reduction in sedative dosage when APs were present. Conclusions: Offering to permit the presence of an accompanying person during EGD was often shown to improve patient satisfaction and reduce anxiety.
A preliminary study of micro-gestures : dataset collection and analysis with multi-modal dynamic networks

Micro-gestures (MG) are gestures that people performed spontaneously during communication situations. A preliminary exploration of Micro-Gesture is made in this thesis. By collecting recorded sequences of body gestures in a spontaneous state during games, a MG dataset is built through Kinect V2. A novel term ‘micro-gesture’ is proposed by analyzing the properties of MG dataset. Implementations of two sets of neural network architectures are achieved for micro-gestures segmentation and recognition task, which are the DBN-HMM model and the 3DCNN-HMM model for skeleton data and RGB-D data respectively. We also explore a method for extracting neutral states used in the HMM structure by detecting the activity level of the gesture sequences. The method is simple to derive and implement, and proved to be effective. The DBNHMM and 3DCNN-HMM architectures are evaluated on MG dataset and optimized for the properties of micro-gestures. Experimental results show that we are able to achieve micro-gesture segmentation and recognition with satisfied accuracy with these two models. The work we have done about the micro-gestures in this thesis also explores a new research path for gesture recognition. Therefore, we believe that our work could be widely used as a baseline for future research on micro-gestures.
Submillimeter galaxies behind the Bullet Cluster (1E 0657-56)

Context. Clusters of galaxies are effective gravitational lenses able to magnify background galaxies and making it possible to probe the fainter part of the galaxy population. Submillimeter galaxies, which are believed to be star-forming galaxies at typical redshifts of 2 to 3, are a major contaminant to the extended Sunyaev-Zeldovich (SZ) signal of galaxy clusters. For a proper quantification of the SZ signal the contribution of submillimeter galaxies needs to be quantified. Aims. The aims of this study are to identify submillimeter sources in the field of the Bullet cluster (1E 0657-56), a massive cluster of galaxies at z similar or equal to 0.3, measure their flux densities at 870 mu m, and search for counterparts at other wavelengths to constrain their properties. Methods. We carried out deep observations of the submillimeter continuum emission at 870 mu m using the Large APEX BOlometer CAmera (LABOCA) on the Atacama Pathfinder EXperiment (APEX) telescope. Several numerical techniques were used to quantify the noise properties of the data and extract sources. Results. In total, seventeen sources were found. Thirteen of them lie in the central 10 arcmin of the map, which has a pixel sensitivity of 1.2 mJy per 22 '' beam. After correction for flux boosting and gravitational lensing, the number counts are consistent with published submm measurements. Nine of the sources have infrared counterparts in Spitzer maps. The strongest submm detection coincides with a source previously reported at other wavelengths, at an estimated redshift z similar or equal to 2.7. If the submm flux arises from two images of a galaxy magnified by a total factor of 75, as models have suggested, its intrinsic flux would be around 0.6 mJy, consistent with an intrinsic luminosity below 10(12) L-circle dot.
Optimizing adherence to highly active antiretroviral therapy among marginalized, HIV-positive women with comorbid depression: the role of the nurse practitioner

Women represent a growing proportion of new positive HIV tests in Canada and are more likely to experience comorbid depression. This is concerning because comorbid depression is associated with suboptimal adherence to highly active antiretroviral therapy (HAART) and poor HIV disease outcomes. The purpose of this project is to answer the question, What is the role of the nurse practitioner (NP) in optimizing adherence to HAART amongst marginalized, HIV-positive women with comorbid depression? By evaluating current literature this project found that social factors such as poverty, homelessness, food insecurity, post-traumatic stress disorder, stigmatization, gender or racial discrimination and injection drug use are risk factors for both comorbid depression and HAART non-adherence. Effective treatments for depression include cognitive behavioral therapy and pharmacological intervention with antidepressants. The role of the NP was inferred by extrapolating the findings from this literature search with the competencies required of NP practice. NPs have the skills, education and legislated authority to provide collaborative care that addresses the underlying social factors that contribute to comorbid depression and HAART non-adherence. These findings are limited by the scarcity of research conducted with HIV-positive female participants, that investigates NP practice or interventions to address underlying social factors. --leaf ii.
Innovators and the Diversity of Innovation Systems

This work deals with the determinants of cooperative invention and innovation within innovation systems. Several proximity dimensions are used to identify the levels on which systemic innovation activities can be observed. To disentangle the effects of different proximity dimensions a procedure is suggested to identify the relative regional impact (RRI) on cooperative invention and innovation. Applying this method to German patent data shows that there are significant differences in the RRI of German regions. These differences are related to measures of the technological relatedness of the regions knowledge bases, and over time they show a considerable path dependency.
Impact of Unemployment on Economic Growth in Nigeria 1980 - 2010

This research work focused on the Effect of Unemployment on Economic Growth in Nigeria modeling Gross Domestic Product (GDP) against Unemployment rate, Government Expenditure and Money supply between 1980 – 2010. The research make use of Ordinary Least Square regression technique, the result shows that unemployment does not significantly affect economic growth, but a good performance of an economy in terms of per capita growth may therefore be attributed to the other factors affecting economic growth in the country. A major policy implication of this result is that concerted effort should be made by policy makers to increase the level of output in Nigeria by improving productivity/supply in order to reduce unemployment and the prices of goods and services (inflation) so as to boost the growth of the economy. Another policy implication of this study is that government should embark on labor intensive technique of production as against capital intensive and also close the border to some extent which is the likely measure to reduce unemployment and Inflation and increase domestic output level (GDP).
Fatty acid composition of breast meat in two lines of slow-growing chickens reared conventionally or on pasture

The study was carried out to compare the fatty acid composition of the breast meat in two lines of slow growing chickens - La Belle (LB) and Bresse (BB), reared conventionally or having access to pasture. The differences in the lipid profile due to the lines and rearing strategies were assessed through two-way ANOVA. Both factors influenced the lipid composition in the breast meat, however the effect of pasture was more pronounced. It was associated with lower contents of C14:0, C16:0 and C16:1Δ7 (P<0.001), C18:1 (P<0.05), total saturated (SFA) and monounsaturated fatty acids (MUFA) (P<0.01), and significant increase (P<0.001) of the long chain polyunsaturated fatty acids (PUFA). These changes in the lipid profile of the breast meat in the chickens reared outdoors led to considerably lower atherogenic and thrombogenic indices, reduced n-6/n-3 ratio (P<0.001), as well as higher P/S and h/H values (P<0.001). Differences in the fatty acid composition of the breast meat were also due to the line of the birds, showing advantage of the LB over BB chickens. The former had lower contents of saturated (P<0.001) but higher long chain polyunsaturated fatty acids (P<0.05) which determined better nutritional indices of the breast meat in the LB line.
