Some special geotechnical properties of pumice deposits

Abstract: This paper describes the characteristics of pumice soils from the area of Mount Vesuvius and discusses sinking, watering and other geotechnical tests on pumice from a number of sites. Attention is drawn to the presence of both inter- and intra-particle voids within this material and appropriate modifications to the standard solid-water-air phase diagram are suggested to take account of this. The importance of understanding the structure of the pumice and its response to rainfall/ground water conditions is discussed in relation to both landslips and stabilisation works.

Evaluation of the optimal thermal insulation thickness for an office building in different climates by means of the basic and modified “cost-optimal” methodology

Abstract: Energy consumption for heating and cooling of Italian office buildings is growing. In particular, there is an increase in the demand for electricity for cooling in the summer. Thermal insulation on the external side of the buildings is a very usual strategy to reduce energy demand for air-conditioning systems. However, a too high thickness of insulating material, even if complying with current legislative requirements, can be disadvantageous in buildings characterized by great internal thermal loads and/or located in climatic contexts with mild winters and hot summers. In this paper, the energetic and economic influence of external thermal insulation is evaluated by using energy simulations under dynamic conditions (DesignBuilder software) for a case study. The analysis is performed for various cities (Palermo, Milan and Cairo) and for different values (10, 20, 30 W/m2) of internal thermal loads. According to the recent and innovative “cost-optimal” methodology, optimal insulation thicknesses are derived, and the results demonstrate the need to avoid excessive insulation of buildings to obtain the highest energy saving. Finally, an integration of the “cost-optimal” methodology is proposed considering also the topic of thermal comfort; this modification allows to obtain other optimal solutions compared to the basic calculation procedure.

A statecharts-based software development process for mobile agents

Abstract: Although mobile agents and their supporting infrastructures have been extensively developed, it is still an emerging technology. A wider acceptance of mobile agents would be facilitated with the exploitation of suitable methodologies and tools which fully support their development lifecycle. This paper proposes a Statecharts-based development process for mobile agents, which allows for a seamless transition from the specification of mobile agent behaviour to its implementation and adaptation to target mobile agent systems. In particular, modelling of the mobile agent behaviour is visual and its coding is seamlessly supported by the Mobile Active Object Framework. The coded agent behaviour can be adapted to platform-specific mobile agents by means of the Mobile Agent Adaptation Framework thus enabling re-use of existing mobile agent systems.
