Conversational modeling requires an extended time commitment, and the difficulty associated with capturing the wide range of conversational stimuli necessitates extended user participation. We propose the use of leaderboards, narratives and deadlines as motivation strategies to persuade user participation in the conversational modeling for virtual humans. We evaluate the applicability of leader...

Management of workflow processes is more than just enactment of process activities according to business rules. Time management functionality should be provided to control the lifecycle of processes. Time management should address planning of workflow executions in time, provide various estimates about activity execution durations, avoid violations of deadlines assigned to activities and the en...

This paper studies bilateral multi-issue negotiation between self-interested autonomous agents. Now, there are a number of different procedures that can be used for this process; the three main ones being the package deal procedure in which all the issues are bundled and discussed together, the simultaneous procedure in which the issues are discussed simultaneously but independently of each oth...

Often real-time embedded software is specified as a set of interacting tasks that have local deadlines on subtasks and global deadlines on each task. Currently available scheduling algorithms guarantee only a single level of deadlines, either all local or all global, but not both. We propose a quasi-dynamic scheduling algorithm for simultaneously guaranteeing both types of deadlines, while sati...

This paper introduces an analytical method for approximating the performability of a firm realtime system modeled by a multi-server queue. The service discipline in the queue is earliestdeadline- first (EDF), which is an optimal scheduling algorithm. Real-time jobs with exponentially distributed relative deadlines arrive according to a Poisson process. All jobs have deadlines until the end of s...

Real-time database systems incorporate the notion of a deadline into the database system model. USUally, deadlines are associated with transactions, and the system attempts to execute a given set of transactions so as to both meet the deadlines and ensure the database consistency. This paper presents an alternative model of real-time database processing in which deadlines are associated with co...

Management of workkow processes is more than just enactment of process activities according to business rules. Time management func-tionality should be provided to control the lifecycle of processes. Time management should address planning of workkow executions in time, provide various estimates about activity execution durations, avoid violations of deadlines assigned to activities and the ent...

We develop a two-sided reputational bargaining model with deadlines, and analyze the implications of linking a reputation for commitment on one bargaining issue, to reputation on future issues. The model is adapted from that of Abreu and Gul [2000], where some agents are committed to achieving a fixed share of any surplus available. Among the conclusions drawn are: the ordering of issues on the...

This paper presents a probabilistic approach to guarantee the performance of a real-time system. While traditional real-time system analysis tends to guarantee that each task instance will complete its execution before its absolute deadline (hard guarantee), our approach permits to estimate the probability that it will happen. Such a statistical guarantee is performed based on interarrival and ...
