As mobile applications become more pervasive, the need for assessing their quality, particularly in terms of efficiency (i.e., performance and resource utilisation), increases. Although there is a rich body of research and practice in developing metrics for traditional software, there has been little study on how these relate to mobile context-aware(More)
Distributed mobile applications operate on devices with diverse capabilities, in heterogeneous environments, where parameters such as processor, memory and network utilisation, are constantly changing. In order to maintain efficiency in terms of performance and resource utilisation, such applications should be able to adapt to their environment. Therefore,(More)
This paper proposes, implements, and evaluates in terms of worst case performance, an online metrics collection strategy to facilitate application adaptation via object mobility using a mobile object framework and supporting middleware. The solution is based upon an abstract representation of the mobile object system, which holds containers aggregating(More)
Due to the different nature of the available dynamic interactions between components afforded by some middleware infrastructure, distributed information systems (DIS) behave differently from traditional centralized ones. This results in a different view of their quality attributes, which require specifically customized measures for accurate estimation. In(More)
BACKGROUND Squid oil contains high concentration of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The purpose of this work was to optimize the process of separation by molecular distillation of ω-3 fatty acid ethyl esters obtained from squid oil. The separation process was conducted in two stages in a laboratory-scale molecular distiller. A(More)
