Peers' evaluation of a reconfigurable IEEE1451.0-compliant and FPGA-based weblab
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, Mário; Zutin, D. G.; Zackrisson, J.; Rochadel, Willian; Henandez-Jayo, UnaiIt is already more than 10 years that weblabs are seen as important resources to provide the experimental work required in engineering education. Several weblabs have been applied in engineering courses, but there are still unsolved problems related to the development of their infrastructures. For solving some of those problems, it was implemented a weblab with a reconfigurable infrastructure compliant with the...
Reconfigurable IEEE1451-FPGA based weblab infrastructure
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioWeblabs are spreading their influence in Science and Engineering (S&E) courses providing a way to remotely conduct real experiments. Typically, they are implemented by different architectures and infrastructures supported by Instruments and Modules (I&Ms) able to be remotely controlled and observed. Besides the inexistence of a standard solution for implementing weblabs, their reconfiguration is limited to a se...
Embedding instruments & modules into an IEEE1451-FPGA-Based Weblab infrastructure
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioAdopting standard-based weblab infrastructures can be an added value for spreading their influence and acceptance in education. This paper suggests a solution based on the IEEE1451.0 Std. and FPGA technology for creating reconfigurable weblab infrastructures using Instruments and Modules (I&Ms) described through standard Hardware Description Language (HDL) files. It describes a methodology for creating and bind...
Work-in-progress on a thin IEEE1451.0 - architecture to implement reconfigurabl...
Guedes, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioInstitutions have been creating their own specific weblab infrastructures. Usually, they use distinct software and hardware architectures comprehending instruments and modules (I&M) able to be parameterized but difficult to be shared. These aspects are impairing their widespread in education, since collaboration between institutions, in developing and sharing resources, is still low. To handle both aspects, thi...
Reconfigurable weblabs based on the IEEE1451 Std
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioTechnology plays a double role in Education: it can act as a facilitator in the teaching/learning process and it can be the very subject of that process in Science & Engineering courses. This is especially true when students perform laboratory activities where they interact with equipment and objects under experimentation. In this context, technology can also play a facilitator role if it allows students to per...
FPGA-based weblab infrastructures guidelines and a prototype implementation exa...
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, Mário; Poley, R.; Wishart, C.Recent trends show an increasing number of weblabs, implemented at universities and schools, supporting practical training in technical courses and providing the ability to remotely conduct experiments. However, their implementation is typically based on individual architectures, unable of being reconfigured with different instruments/modules usually required by every experiment. In this paper, we discuss pract...
eCrash: a framework for performing evolutionary testing on third-party Java com...
Ribeiro, José Carlos Bregieiro; Zenha-Rela, Mário Alberto; Fernandéz de Vega, FranciscoThe focus of this paper is on presenting a tool for generating test data by employing evolutionary search techniques, with basis on the information provided by the structural analysis and interpretation of the Java bytecode of third-party Java components, and on the dynamic execution of the instrumented test object. The main objective of this approach is that of evolving a set of test cases that yields full str...
Using dynamic analysis of Java bytecode for evolutionary object-oriented unit t...
Ribeiro, José Carlos Bregieiro; Zenha-Rela, Mário Alberto; Fernandéz de Vega, FranciscoThe focus of this paper is on presenting a methodology for generating and optimizing test data by employing evolutionary search techniques, with basis on the information provided by the analysis and interpretation of Java bytecode and on the dynamic execution of the instrumented test object. The main reason to work at the bytecode level is that even when the source code is unavailable, structural testing requir...
mCrash: a framework for the evaluation of mobile devices trustworthiness proper...
Ribeiro, José Carlos Bregieiro; Zenha-Rela, Mário AlbertoA rationale and framework for the evaluation of mobile devices’ robustness and trustworthiness properties using a Windows Mobile 5.0 testbed is presented. The methodology followed includes employing software faultinjection techniques at the operating system’s interface level and customising tests to the behaviour of the software.
