- Embedded systems are specialized computers used in larger systems or machines to control equipments such as automobiles, home appliances, communication, control and office machines. Such pervasivity is particularly evident in immersive realities, i.e., scenarios in which invisible embedded systems need to continuously interact with human users, in order to provide continuous sensed information and to react to service requests from the users themselves. The SM4All project investigates an innovative middleware platform for inter-working of smart embedded services in immersive and person-centric environments, through the use of composability and semantic techniques for dynamic service reconfiguration. This is applied to the challenging scenario of private houses and home-care assistance in presence of users with different abilities and needs (e.g., young, able-bodied, aged and disabled). This paper presentes a brief overview of the SM4All system architecture.

- The objective of this work is to study theoretically and experimentally the mass transfer during the isothermal drying of acetylsalicylic acid. In the first part, internal mass transfer during isothermal drying of porous bed of acetylsalicylic acid, partially saturated with single solvents has been experimentally and theoretically studied. Drying experiments with water and ethanol as single solvents were performed at different temperatures and transient liquid content profiles were determined. The parameters to describe the retention properties of the solid and the capillary movement of the liquid were determined by comparing experimental data and calculation from a developed mathematical model. In the second part, isothermal drying kinetics of a porous bed of acetylsalicylic acid was examined performing experiments in a tunnel dryer. The Crank solution to the unidirectional mass balance and the model with transport parameters developed in the internal mass transfer part were compared with the experimental drying curves. Particular characteristics reveled during the internal mass transfer experiments demands additional study on the behavior of the solid, probably closely related to dissolution and crystallization processes.
