The problem of scheduling under resource constraints is widely applicable. One prominent example is power management, in which we have a limited continuous supply of power but must schedule a number of power-consuming tasks. Such problems feature tightly coupled continuous resource constraints and continuous temporal constraints. We address such problems by introducing the Time Resource Network...

On the one hand, class ical terminological knowledge representation excludes the possi­ bility of handling uncertain concept descrip­ tions involving, e.g., "usually true" concept properties, generalized quantifiers, or excep­ tions. On the other hand, purely numer­ ical approaches for handling uncertainty in general are unable to consider terminologi­ cal knowledge. This paper presents the lan...

Due to the recent technological advances, real-time hybrid dynamical systems are becoming ubiquitous. Most of these systems behave unpredictably, and thus, exhibit uncertainty. Hence, a formal framework to model systems with unpredictable behaviours is needed. We develop Probabilistic Constraint Nets (PCN), a new framework that can handle a wide range of uncertainty, whether it be probabilistic...

Segmentation of femurs in Anterior-Posterior x-ray images is very important for fracture detection, computer-aided surgery and surgical planning. Existing methods do not perform well in segmenting bones in x-ray images due to the presence of large amount of spurious edges. This paper presents an atlas-based approach for automatic segmentation of femurs in x-ray images. A robust global alignment...

resource constraints project scheduling problem (rspsp) seeks proper sequence of implementation of project activities in a way that the precedence relations and different type of resource constraints are met concurrently. rcpsp tends to optimize some measurement function as make-span, cost of implementation, number of tardy tasks and etc. as rcpsp is assumed as an np-hard problem so, different ...

We propose a probabilistic extension of Allen’s Interval Algebra for managing uncertain temporal relations. Although previous work on various uncertain forms of quantitative and qualitative temporal networks have been proposed in the literature, little has been addressed to the most obvious type of uncertainty, namely the probabilistic one. More precisely, our model adapts the probabilistic Con...
