The level 1 highest weight modules of the quantum affine algebra Uq(ŝln) can be described as spaces of certain semi-infinite wedges. Using a q-antisymmetrization procedure, these semi-infinite wedges can be realized inside an infinite tensor product of evaluation modules. This realization gives rise to simple descriptions of vertex operators and (up to a scalar function) their compositions. 1 R...

Introduction One of the features that distinguishes intelligent agents is their flexibility: generally they have the ability to accomplish a task in a variety of ways. Such flexibility is necessary if the agent is to be able to accomplish a variety of tasks under a range of conditions. Yet this flexibility also poses a problem: how do we communicate to such an agent the task we want accomplishe...

Anticipatory motor planning abilities mature as children grow older, develop throughout childhood and are likely to be stable till the late sixties. In the seventh decade of life, motor planning performance dramatically declines, with anticipatory motor planning abilities falling to levels of those exhibited by children. At present, the processes enabling successful anticipatory motor planning ...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

Conventional production systems are characterised by central planning and control methods, which show a wide range of weaknesses regarding flexibility and adaptability of the production system to environmental influences. Centralised planning and control methods are based on simplified premises (predictable throughput times, fix processing times of production orders etc.), which lead to an inad...

This paper presents a method for modeling robot and human resources in the context of assembly systems planning. In assembly systems, several redundant resources can be used to increase system flexibility. However, the “quality” of a sequence planning strongly depends on the “quality” of the system modeling. Furthermore, occurrence of unexpected events or variations in availability of resources...
