An Empirical analysis of Open Source Software Defects data through Software Reliability Growth Models
Full text linkThe purpose of this study is to analyze the reliability growth of Open Source Software (OSS) using Software Reliability Growth Models (SRGM). This study uses defects data of twenty five different releases of five OSS projects. For each release of the selected projects two types of datasets have been created; datasets developed with respect to defect creation date (created date DS) and datasets developed with respect to defect updated date (updated date DS). These defects datasets are modelled by eight SRGMs; Musa Okumoto, Inflection S-Shaped, Goel Okumoto, Delayed S-Shaped, Logistic, Gompertz, Yamada Exponential, and Generalized Goel Model. These models are chosen due to their widespread use in the literature. The SRGMs are fitted to both types of defects datasets of each project and the their fitting and prediction capabilities are analysed in order to study the OSS reliability growth with respect to defects creation and defects updating time because defect analysis can be used as a constructive reliability predictor. Results show that SRGMs fitting capabilities and prediction qualities directly increase when defects creation date is used for developing OSS defect datasets to characterize the reliability growth of OSS. Hence OSS reliability growth can be characterized with SRGM in a better way if the defect creation date is taken instead of defects updating (fixing) date while developing OSS defects datasets in their reliability modellin

Functional assessment of urban forested wetlands.
Full text linkWetlands perform various functions of vital socio-ecological significance. To avoid further loss of functions, functional assessment techniques for management purposes are important to develop for different wetland classes. Our aim was to assess the biotic functions of urban-forested wetlands, and to evaluate specific functional assessment models in an urban setting. The models were adopted from the low gradient riverine wetlands hydrogeomorphic (HGM) functional assessment guidebook of Western Kentucky of the US Army Corps of Engineers. Three bottomland hardwood wetlands were chosen for assessment and models evaluation in East Baton Rouge Parish (EBRP), Louisiana. Fourteen out of 17 variables for nutrient cycling, maintenance of native plant community and provision of habitat for wildlife functions were applicable to the selected wetlands. Three surrogate variables were developed to fill identified gaps in the existing models and provide more accurate assessment of urban forested wetlands. Litter layer depth was found to be a more reliable assessment variable for quantifying Ohorizon biomass production than the presence/absence of an O-horizon. Dominant wetlands plant species list was adjusted to accurately reflect the flora of the urban forested wetlands of EBRP. An additional variable for characterization of forest strata as a factor of wildlife habitat provision was developed, and added to the model. Overbank flood frequency variable was not applicable to the fragmented urban wetlands and was removed from the models. The amended assessment models accurately captured existing wetland conditions and the effects of site alterations due to urbanization. These alterations caused significant differences (p <0.05) in wildlife habitat provision, maintenance of characteristic plants community and nutrient cycling functions among the three sites. Further work on the application of these models in similar urban forested settings in the southeastern US is recommended
