ing the behaviours of separate actions into a single composite action allows groups of actions to be coordinated instead of multiple individual actions. Returning to the example in section 4.1, this can be done by time-slicing the plan into subplans with homogenous states. These sub-plans are formalized by conjunctions of a temporal constraint, action states, and action superposition applied to...

A time series model is presented that uses historical project information to predict the number of future defects, given the number of proposed features and improvements to be completed. This allows for hypothetical release plans to be compared by assessing their predicted impact on testing and defect-fixing time. We selected the VARX time series model as a reasonable approach. The accuracy of ...

This paper proposes a fast alternative to POMDP planning for domains with deterministic state-changing actions but probabilistic observation-making actions and partial observability of the initial state. This class of planning problems, which we call quasi-deterministic problems, includes important realworld domains such as planning for Mars rovers. The approach we take is to reformulate the qu...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

Abstract Due to the severe flight environment, hypersonic vehicles are susceptible external disturbances and aerodynamic parameter uncertainties, dramatically challenging precise control stable tracking. This paper presented a fixed-time disturbance observer (FTDO) obtain better tracking performance for vehicles. The FTDO can improve under perturbations, whose observation time is bounded does n...

The present article provides a sufficient condition to ensure output finite-time and fixed-time stability. Comparing with analogous researches the proposed result is less restrictive obtained for wider class of systems. presented stability used adaptive control design, where state vector plant extended by adjustable parameters.
