Movies are one of the biggest sources of entertainment, in individual and social contexts, and increasingly accessible as enormous collections of videos and movies over the Internet, in social media and interactive TV. These richer environments demand for new and more powerful ways to search, browse and view videos and movies, that may benefit from video(More)
Wood density and pulp yield are key parameters in the evaluation of tree productivity and quality for pulping and their relationships are of high practical importance. The influence of wood density on pulp yield and other pulp quality parameters was investigated using Acacia melanoxylon and its natural variability as a case study. Twenty trees were(More)
This paper describes a process, implemented using two simulation engines that adopt, respectively, the event scheduling paradigm and the activity scanning paradigm. The process being modeled is design development in an unpredictable environment. Unpredictability means that criteria are prone to change during design, thereby interrupting ongoing work and(More)
This paper presents a process simulation model representative for design development of a building system in an unpredictable environment. Unpredictability means that design criteria are prone to change as design development unfolds. The model was implemented with a discrete-event simulation engine based on event graphs. Events capture moments when tasks(More)
The antioxidant activity of the phenolic compounds present in industrial black liquors obtained from the two cooking processes (kraft and sulphite) used in Portugal to produce Eucalyptus globulus pulp was evaluated. The black liquors treated at several pH values were extracted with ethyl acetate. Phenolic fractions were further separated by liquid(More)
