A three-dimensional transient formulation of the frost formation process is developed by means of a finite volume approach. Emphasis is put on the frost surface boundary condition as well as the wide range of empirical correlations related to the thermophysical and transport properties of frost. A study of the numerical solution is made, establishing the parameters that ensure grid independence...

The move to the cloud brings a number of new security challenges, but the application remains your last line of defense. Engineers are extremely well poised to perform tasks critical for securing the application—provided that certain key obstacles are overcome. Cloud Shifts the Burden of Security to Development

Penetration testing entails attacking a system to identify and report insecurity, but doing so without harming the system nor encroaching on the dignity of those affected by it. To improve the interaction between penetration testers and their processes and technology, we need to understand the factors that affect decisions they make with ethical import. This paper presents four ethical hazards ...

This paper reports about the analysis of the Internet diffusion among families and business basing on daily observations on registrations of second level domain names underneath the “.it” ccTLD . In particular, domains registered by individuals are analysed. The penetration rate over the relevant population of potential adopters is computed at highly disaggregated geographical level (province)....
