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)
Clusters composed of fast personal computers are now w ell established as cheap and eecient platforms for distributed and parallel applications. The main drawback of a standard NOWs is the poor performance of the standard inter-process communication mechanisms based on RPC, sockets, TCPPIP, Ethernet. Such standard communication mechanisms perform poorly(More)

Among lifestyle factors, nutrition is one of the most important determinants of health, and represents a pivotal element of cancer risk. Nonetheless, epidemiological evidences of the relationship between several cancers and specific foods and nutrients is still inadequate, and solid conclusions are missing. Indeed, caloric restriction without malnutrition(More)
