This volume collects all papers accepted for presentation at Ontobras 2015, the VII Brazilian Ontology Research Seminar (7o Seminário de Pesquisa em Ontologias no Brasil), held on September 7-10, 2015 in Sao Paulo, Brazil. In its 7th edition, we sincerely hope Ontobras to be once more a valuable and pleasant opportunity for researchers and practitioners from Information Sciences and Computer Sc...

stress and residual stress are the main problems in the operating performance of materials. they are the principal causes of material failure and can affect life time of component. however measurement or predictions of them are typically difficult. two common non-destructive methods, x-ray diffraction and ultrasound are not reliable methods for subsurface residual stress measurements and destru...

The development teams who are geographically spread, culturally mixed and mainly depend on information and communication technology (ICT) for communication is defined as a global virtual teams (GVTs). Despite the advancement of technologies, achieving the efficient performance of GVTs remains a challenge. The reviewed literature has highlighted the importance of training and development, organi...

This paper presents the key features and performances of a “real-time” spherical near-field antenna measurement system. This system which is based on the use of an array of measurment probes has been specifically designed for the wireless telecommunciations market. The measurement speed and mechanical configuration are such that measurements of the interactions between the human body and person...

a method based on electrical capacitance tomography (ect) and an improved least squares support vector machine (ls-svm) is proposed for void fraction measurement of oil-gas two-phase flow. in the modeling stage, to solve the two problems in ls-svm, pruning skills are employed to make ls-svm sparse and robust; then the real-coded genetic algorithm is introduced to solve the difficult problem of ...

The aim of this study was to investigate the use of variety of financial and non-financial performance measures identified in performance measurement systems literature. Based on survey responses from 87 Financial Managers, performance measurement diversity explains how participation leads to a greater level of system satisfaction. Furthermore, the results using structural equation modeling ind...
