One of the problems of real-life production scheduling is dynamics of manufacturing environments with new production demands and breaking machines during the schedule execution. Simple rescheduling from scratch in response to unexpected events occurring on the shop floor may require excessive computation time. Moreover, the recovered schedule may be prohibitively deviated from the ongoing sched...

Continuing the work begun in [2], we investigate the relationships among selective, normal and pleasant ideals. Our major result is that any selective ideal extending NSκ is normal.

This work describes the application of the schedule-based approach when dealing with the Grid scheduling problem. We present the advantages as well as the common problems related to this approach. In contrast to the classical queue-based approach, schedule-based approach is much more influenced by the natural dynamics and the uncertainty present in the Grid. Therefore, we propose some general t...

In general, sad music is thought to cause us to experience sadness, which is considered an unpleasant emotion. As a result, the question arises as to why we listen to sad music if it evokes sadness. One possible answer to this question is that we may actually feel positive emotions when we listen to sad music. This suggestion may appear to be counterintuitive; however, in this study, by dividin...

The autobiographical memory literature has established that people remember poorly unpleasant, relative to pleasant, life events. We complemented this literature with a theoretical model – the mnemic neglect model – and an experimental paradigm that exerts tight control over the to-be-remembered material. Participants recall poorly self-threatening feedback compared to self-affirming or other-r...

A novel approach to reconciling global optimizing scheduling with real-time dispatching is presented. High speed scheduling is accomplished by two simultaneous cooperating scheduling processes, one of which generates longer term schedules while the other is focused with higher resolution on the nearer term. Real-time dispatching is based on the most recently generated near term schedule, carefu...

Previous research on mood dependent memory (MDM) suggests that the more one must rely on internal resources, rather than on external aids, to generate both the target events and the cues required for their retrieval, the more likely is one's memory for these events to be mood dependent. To instantiate this "do-it-yourself" principle, three experiments were conducted in which Ss experiencing eit...
