descriptions of library components, the bug-fixing history, the code change history, and the file dependency graph. Given a bug report, the ranking score of each source file is computed as a weighted combination of an array of features, where the weights are trained automatically on previously solved bug reports using a learning-to-rank technique. I applied SVM (Support Virtual Machine) to classify the bug reports to identify, which category the bug belongs to. It helps to fix the critical defects early

Semantic similarity measures usage is prevalent in pervasive computing with the following aims: 1) to compare the components of an application; 2) to recommend and rank services by degree of relevance; 3) to identify services by matching the description of a query with the available services; 5) to compare the current context with already known contexts. The existing works that apply semantic similarity measures to pervasive computing focus on one particular issue. Furthermore, surveys in this

Then, whether there is an association between the changes in blood variables and growth measurements was examined by Spearman’s Rank-Order Correlation. The threshold for statistical significance was set as p<0.01 in all calculations.

The Kumaraswamy distribution is the most widely applied statistical distribution in hydrological problems and many natural phenomena. We propose a generalization of the Kumaraswamy distribution referred to as the transmuted Kumaraswamy (𝑇𝐾𝑤) distribution. The new transmuted distribution is developed using the quadratic rank transmutation map studied by Shaw et al. (2009). A comprehensive account of the mathematical properties of the new distribution is provided. Explicit expressions are

OF THE RESEARCH The purpose of this work is to propose an approach to assess the effects of accidents in sewer tunnels. To achieve the purpose of the research, the following objectives were defined: to identify the main causes of deterioration of sewer tunnels provoking the occurrence of emergencies; to identify the consequences of emergencies in sewer tunnels; to propose a comprehensive approach to assess the consequences of occurrence of emergencies in sewer tunnels using a rank scale that

Differences in distribution and community structure of plant-parasitic nematodes in pecan orchards between two ecoregions of Georgia

(McCune and Mefford, 2016). To test for statistically significant differences between the Piedmont and Coastal Plant pecan PPN communities, we retained the primary matrix (ln x + 1 transformed) and secondary matrix in the NMDS analysis and used them both for Multi-Rank Permutation Procedure (MRPP) (Mielke and Berry, 2001). MRPP is similar to an ANOVA but it is used for multivariate data. It evaluates group membership by comparing the distance values from each sample in the a priori selected groups

referred to above were formulated and were then verified by performing a quantitative data analysis, relying on Spearman’s rank correlation coefficient and the chi-square test of independence. A statistically significant correlation between brand image and equity, on the one hand, and between brand awareness and image, on the other, has been identified based on the survey. The research confirms the importance of brand equity in the development of business operations, mainly due to the existence

with the requirements of the external environment. A multi-stage methodological approach was used. Selection criteria obtained from the systematic review of literature were first carefully analysed to find potential shortcomings. After that, a cluster method was used to reduce the number of criteria and to aggregate similar criteria. A Pareto analysis (75/25 rule) was further used to rank the criteria according to their frequency of use and consequently according to importance. The obtained

The positional MEF-TOPSIS method for the assessment of complex economic phenomena in territorial units

In this paper, the authors propose a new methodological approach to the construction of a synthetic measure, where the objects are described by variables with strong asymmetry and extreme values (outliers). Even a single extreme value (very large or very small) of a variable for the object may significantly affect the attribution of an excessively high or low rank in the final ranking of objects. This dependence is particularly apparent when using the classical TOPSIS (Technique for Order of

The association between chronological age, skeletal maturity and dental maturity

. Dental age (DA) was determined using the simple weighted average method. Results: There was no significant difference between DA and chronological age (CA) of the male and female groups. The Spearman rank correlation between CA and CVM was moderate, whilst the correlation between DA and CVM was weak. A moderate correlation was found between the dental calcification stages and CVM for the upper right third molar in males. Conclusions: The average CA of females at every CVM stage was below that of

High-dose 1,25-dihydroxyvitamin D supplementation elongates the lifespan of Huntington’s disease transgenic mice

: 73 (67–94) days vs. vitamin D3-supplemented group: 101 (74–109) days, p=0.048 Mantel-Cox log rank test). Conclusions: Further investigations are needed to determine whether a neuroprotective or a general corroborative effect of vitamin D leads to the measured effect. Our findings support the potential influence of vitamin D deficiency on the disease course and propose that vitamin D may be an effective supplementary treatment to beneficially influence clinical features

The Spearman’s rank correlation coefficient (Spearman’s rho: ρ) was used to calculate the correlation between raters in assessing Achilles tendon structure and measuring the anteroposterior tendon diameter(15). Interrater reliability for evaluation of the Achilles tendon structure was calculated as weighted Kappa-coefficient (kw)(16). The Wilcoxon signed-rank test was applied to evaluate quantitative differences between sonographers in measuring the tendon diameter. Bland-Altman plots were

A comparison of the sagittal and vertical dentofacial effects of maxillary expansion produced by a memory screw and a hyrax screw

were homogeneous. To determine the treatment changes within the groups, a paired t-test and Wilcoxon Signed Rank test were applied to the homogeneous and non-homogeneous parameters, respectively. A comparison between the groups was carried out using the Student’s t-test for homogeneous parameters and the Mann-Whitney U test for all others. Results: A results summary indicates that mid-palatal sutural opening and subsequent important skeletal and dental expansions were obtained in all patients

7.8 – 12.9 yr). Treatment changes were analysed on lateral cephalograms taken 6–12 months prior to commencing treatment (T1) and at the finish of the orthopaedic phase (T2). Where a normality assumption was met, a parametric paired-sample t-test was used to assess the change differences at T1 and T2. For non-normal data, a non-parametric Wilcoxon sign rank test for related samples was used to assess T1 and T2 differences. The level of statistical significance was set at p < 0.05 (2

A laser Doppler flowmeter (LDF) was used to measure PBF at baseline (T0) and during incisor intrusion at 24 hours (T1), three days (T2), seven days (T3) and three weeks (T4). Statistical changes in PBF were assessed by the Wilcoxon Signed Rank and Mann-Whitney U tests, with significance set at p < 0.05. Results: The mean PBF in the UA and MI groups decreased significantly from T0 to T1
