Most current planners assume complete domain models and focus on generating plans that are correct with respect to them. Unfortunately, assuming model completeness is unrealistic in the real world, where domain modeling remains a hard, labor-intensive and errorprone task. While domain experts cannot guarantee completeness, often they are able to circumscribe the incompleteness of the model by p...

In previous work we have investigated a framework for distributed temporal plan repair. Using temporal constraints for activities to be executed, we developed a distributed algorithm capable of dealing with temporal changes (disruptions) in these constraints to perform fast plan repair. This framework, however, did not include resource management issues. In this paper, we extend our framework t...

Plans with temporal flexibility have been used to allow discrete systems to adapt to disturbances that occur while the plan is being executed. To control more complex devices, such as bipedal walking machines, we must extend this execution paradigm to the control of hybrid (discrete/continuous) systems. Systems of this type are difficult to control for two reasons: 1) their high dimensionality ...

coordinated and the end result is an integrated, functional organism. Similarly, there is considerable flexibility for evolutionary change of specific parts, while robustness of the overall body plan ensures continued integration of multiple organismal functions. Research in recent years has identified the modular architecture of organisms as one of the major principles that underlies this simu...

PURPOSE The purpose of this study was to quantify the target coverage, homogeneity, and robustness of the dose distributions against geometrical uncertainties associated with four whole breast radiotherapy techniques. METHODS The study was based on the planning-computed tomography-datasets of 20 patients who underwent whole breast radiotherapy. A total of four treatment plans (wedge, field-in...

A major goal of evolutionary developmental biology (evo-devo) is to understand how multicellular body plans of increasing complexity have evolved, and how the corresponding developmental programs are genetically encoded. It has been repeatedly argued that key to the evolution of increased body plan complexity is the modularity of the underlying developmental gene regulatory networks (GRNs). Thi...

  In zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. The proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be ap...
