Proceedings of the Sixth Workshop on Nonmonotonic Reasoning, Action, and Change (NRAC-05), Edinburgh, Scotland, 2005. We use ranking functions to reason about belief change following an alternating sequence of actions and observations. At each instant, an agent assigns a plausibility value to every action and every state; the most plausible world histories are obtained by minimizing the sum of these values. Since plausibility is given a quantitative rank, an agent is able to compare the plausibility of actions and observations. This allows action occurrences to be postulated or refuted in response to new observations. We demonstrate that our formalism is a generalization of our previous work on the interaction of revision and update., Conference paper, Published.
Proceedings of Second International Building Physics Conference: 14 September 2003, Leuven, Belgium. A systematic investigation of the hygrothermal properties of a number of oriented strand boards, plywood products, wood fibreboards and composite wood sidings has resulted in new information on the variations of thermal conductivity, water vapour permeability, moisture diffusivity, sorption- desorption-suction isotherms, water absorption coefficient and air permeability of these classes of products in North America. The experimental and analytical procedures used in the investigation are all based eitheron International Standards or on well-documented and peer-reviewed approaches. This paper presents the description of the products in each category and detailed information on the range of properties. The details include, density and temperature dependences of thermal conductivity,dependence of vapour resistance factor on relative humidity, dependence of moisture diffusivity on moisture concentration, equilibrium moisture content for the full range of relative humidity, variations in the water absorption coefficients and dependence of air permeability on pressure difference., Conference paper, Published.
