In Brazil, power generating, transmitting and distributing companies operating in the regulated market are paid for their equipment availability. In case of system unavailability, the companies are financially penalized, more severely, on unplanned interruptions. This work presents a domain driven data mining approach for estimating the risk of systems’ unavailability based on their component e...

OBJECTIVE To identify the factors that prolong the length of stay inthe post anaesthesia care unit (PACU). METHODS This audit was conducted in the PACU of a university hospital. A special form was designed and filled for those patients who stayed unplanned in the PACU for more than two hours. All patients who were admitted to the PACU after surgery were included. Patients undergoing cardiotho...

In this paper we provide efficient robust algorithms for shunting problems concerning the reordering of train cars over a hump. In particular, we study algorithms able to cope with small disruptions, as temporary and local unavailability and/or malfunctioning of key resources that can occur and affect planned operations. To this aim, a definition of robust algorithm is provided. Performances of...

Understanding object and its context are very important for robots when dealing with objects for completion of a mission. In this paper, an Affordance-based Ontology (ABO) is proposed for easy robot dealing with substantive and non-substantive objects. An ABO is a machine-understandable representation of objects and their relationships by what it’s related to and how it’s related. By using ABO,...

Due to the impact of time-dependent unit unavailability, the testing strategies (e.g., simultaneous or staggered testing) have significant effect on the system unavailability for complex standby systems. Several testing strategies have been studied to minimize average system unavailability for certain systems. For example, uniformly staggered testing has been shown to be the best for two identi...

Halvorsen, K., and Halvorsen, S. (1973). Archives of Disease in Childhood, 48, 842. The 'early anaemia'; its relation to postnatal growth rate, milk feeding, and iron availability: experimental study in rabbits. In infants, the mechanism of the postnatal fall in haemoglobin to levels below those in adults, the 'early anaemia', is still unclear. In rabbits (as well as in other species) the 'earl...
