Contemporary evidence suggests that most field faults in software applications are found in a small percentage of the software’s components. This means that if these faulty software components can be detected early in the development project’s life cycle, mitigating actions can be taken, such as a redesign. For object-oriented applications, prediction(More)
Traditional requirements for persistence layers do not consider limitations of the development platforms available for mobile devices. In order to facilitate the development of applications, which need to store data, for mobile devices, these traditional requirements are reevaluated in this paper and a framework for object persistence is proposed. This(More)
In the database area, elasticity of cloud computing has required data systems to increase and decrease their resources on demand. However, traditional benchmark tools for data systems are not sufficient to analyze some specificities of these systems in a cloud. New metrics for elasticity are needed to provide an indicator both from consumer and provider(More)
Cloud computing is a trend of technology aimed at providing on-demand services with payment based on usage. To improve the use of resources, providers adopt multi-tenant approaches, reducing the operation costs of services. Moreover, tenants have irregular workload patterns, impacting in the guarantees of quality of service, mainly due to interference(More)
The results of therapy given to 74 children with advanced disease, abdominal non-Hodgkin's lymphoma were retrospectively evaluated with respect to the major prognostic factors related to disease outcome. The first 36 patients admitted in the study were treated with a modified LSA2-L2 protocol, and the remaining patients received the same regimen with the(More)
BACKGROUND Well-differentiated papillary mesothelioma (WDPM) is a rare variant of epithelioid mesothelioma and is considered to be associated with good prognosis due to its clinically indolent behavior and long survival. Most reported cases involve the peritoneum of women at reproductive age with no history of exposure to asbestos, with pleural involvement(More)
INTRODUCTION In 2006, the Vila Nova de Gaia/Espinho Hospital Centre Pulmonary Oncology Unit started performing EGFR (Epidermal Growth Factor Receptor) mutation sequencing in selected patients with NSCLC and systematically in all patients since 2010, regardless of histology, smoking habits, age or sex. The aim of this study was to characterize the group of(More)
A relationship between patients with a genetic predisposition to and those who develop postoperative delirium has not been yet determined. The aim of this study was to determine whether there is an association between apolipoprotein E epsilon 4 allele (APOE4) and delirium after major surgery. Of 230 intensive care patients admitted to the post anesthesia(More)
Database systems serving cloud platforms must handle a large number of applications or tenants. Multi-tenancy database has been prevalent for hosting multiple tenants within a single DBMS while enabling effective resource sharing. Providing such performance goals is challenging for providers as they must balance the performance that they can deliver to(More)
