In this paper, we address the problem of scheduling hybrid task sets consisting of hard periodic and soft aperiodic tasks that may share resources in exclusive mode in a dynamic environment, where tasks are scheduled based on their deadlines. Bounded blocking on exclusive resources is achieved by means of a dynamic resource access protocol which also prevents deadlocks and chained blocking. A t...

The Lazarillo of Tormes' picaresque novel introduces a story where two subjects sequentially extract (one, two or three) tokens from a common pool in an asymmetric information framework (the first player cannot observe her partners' actions). By introducing a reward for both subjects in case that in every period at least one subject had taken one single token, we define an interesting coordinat...

In the framework of projects ChinFaDial and ERIM we have developed in recent years several platforms allowing to handle various aspects of bilingual spoken dialogues on the web —mainly, spontaneous speech corpus collection through distant human interpreting. Current development of the core ERIM-Interp and ERIM-Collect platforms now includes multimodal user interaction, integration of some machi...

Many economic decisions are susceptible to either free-riding, or excessive rivalry or overextraction. Equally sharing output in partnerships introduces a free-riding incentive which may offset the latter. We conduct a laboratory experiment to assess the performance of output sharing in partnerships by introducing equal-sharing subgroups of size one, four and six into a twelve-person common poo...

Digital information resources on the web have been playing an important role during the information and knowledge propagation. Advanced applications such as intelligent information retrieval and information recommendation need the semantic relations among the digital information resources. Massive hyperlinks have existed in the current web; however, the semantic relations among the information ...

The congestion pricing is an efficient allocation approach to mediate demand and supply of network resources. Different from the previous pricing using Affine Marginal Cost (AMC), we focus on studying the game between network coding and routing flows sharing a single link when users are price anticipating based on an Average Cost Sharing (ACS) pricing mechanism. We characterize the worst-case e...

Accountability is becoming a major concern for the Internet. Wide spread of misconduct by profit driven hackers makes trust (faith)-based applications vulnerable to malicious attacks. An evidence based resource management system can guarantee that collaborative parties will share their resources based un-deniable evidence, so that community members cannot abuse their privileges without being ca...
