In this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. For this, four reliability indices are considered in objective function;which are as follows: System Average Interruption Frequency Index (SAIFI), System AverageInterruption Duration Index (SAI...

In this paper, an M/M/1 queue with working vacation and vacation interruption is investigated. The server is supposed to take a working vacation whenever the system becomes empty and if there are at least N customers waiting in the system at a service completion instant, vacation interruption happens and the server resumes a normal working period. A matrix geometric approach is employed to obta...

Interruptions are important for effective collaborative work, because agents often possess information required by others on their team. This need to get information from another agent arises in mixed human-computer teams as well as in homogeneous computer-agent environments. For example, a (human) driver may see changes in weather conditions that affect route selection while an automated navig...

We investigated the recovery from memory of a primary task after an interruption. If the primary task lacked associative support among its task components, recovery was more difficult following an interruption that overlapped either completely or partially in the amount of information shared with the primary task (an interruption-similarity effect). In addition, memory for completed actions was...

Two interruption handling strategies were distinguished based on experimental data. Reactive strategy implies an immediate switch from the main task after the onset of interruption. Proactive strategy relies on investing additional processing in the creation of a stable, interference-resistant representation of the main task. It is shown that in the though proactive strategy is associated with ...

A LOCALIZED NARROWING of the IAJL aorta at or distal to the ductus arteriosus (coaretation of the adult type) is one of the most comnlon congenital nmalformations of the great vessels. A narrowing of the aorta proximal to a patent ductus arteriosus (coaretation of the infantile type) is less commoni, while complete interruption of the aorta proximal to the ductus is quite rare, and interruption...
