While mixed reality has inspired the development of many new musical instruments, few approaches explore the potential of mobile setups. We present a new musical interaction concept, called opportunistic music. It allows musicians to recreate a hardware musical controller using any objects of their immediate environment. This approach benefits from the physical attributes of real objects for co...

Grids are becoming mission-critical components in research and industry, offering sophisticated solutions in leveraging largescale computing and storage resources. Grid resources are usually shared among multiple organizations in an opportunistic manner. However, an opportunistic or “best effort” quality-of-service scheme may be inadequate in situations where a large number of resources need to...

The increasing trend on wireless-connected devices makes opportunistic networking a promising alternative to existing infrastructure-based networks. However, on these networks there is neither guarantee about the availability of the connections nor on the topology of the network. The development of opportunistic applications, i.e., applications running over opportunistic networks, is still in e...

A new view of multi-agent systems is emerging within a variety of scholarly fields, from distributed artificial intelligence to sociology and organisation science. The hallmark of this view is a recognition of multi-agent systems as inherently complex and computational systems in which cognition occurs at multiple levels, not only within the individual agent, but as an emergent phenomenon from ...

In this paper, we present a model of oppor-tunistic planning that uses planning-time rear soning about the opportunities that might arise during plan execution. The model is composed of three parts: a planning-time mechanism that places blocked goals into memory for later activation, an understanding system that activates suspended goals as a by-product of parsing the world, and an execution-ti...

A predominant concern in ubiquitous computing (UC) is the natural and effortless interaction of humans with a smart environment in order to carry out a certain task or simply to make life easier. Often, interaction is bootstrapped with a user’s personal, mobile device. Such a device may carry a digital representation in form of a user profile and a key pair that serves as a digital identity. Ex...

Are minorities more vulnerable to opportunism? We find that individuals from a minority group face greater danger of being cheated by an opportunistic firm because trade with the group is less frequent and the value of a reputation for fairness toward the group is correspondingly smaller. If the majority is sufficiently large it can only lose from a solidarity strategy of punishing opportunism ...
