The prevalence of smart wearable devices is increasing exponentially and we are witnessing a wide variety of fascinating new services that leverage the capabilities of these wearables. Wearables are truly changing the way mobile computing is deployed and mobile applications are being developed. It is possible to leverage the capabilities such as connectivity, processing, and sensing of wearable...

For better application-level controls on mashups, we advocate extending the Single Origin Policy and associated primitives to support a cooperative model that allows applications to express explicit sharing policies over browser, Javascript, and physical resources. First, we introduce an isolation model for content loading that is more complete than those of surveyed browser proposals. Second, ...

In the design of embedded systems, it is very important to reduce energy consumption and thus prolong battery life in everywhere existed battery-powered embedded systems. Dynamic voltage scaling (DVS) processors, which support many operating voltages and speeds, can efficiently reduce energy consumption by making appropriate decisions on the processor speed/voltage during the scheduling of real...

In this chapter, we evaluate the feasibility of intelligent and distributed control of shared resources in user-managed networks. The user-managed network paradigm has become possible with the advent of broadband wireless networking technologies such as IEEE 802.11. In those networks, node cooperation can optimize the usage of shared external accesses to the Internet (set of links between the u...

The World Wide Web has evolved into a distributed network of web applications facilitating the publication of information on a large scale. Judging whether such information can be trusted is a difficult task for humans, often leading to blind trust. In this paper we present a model and the corresponding veracity ontology which allows trust to be placed in web content by web agents. Our approach...

Grasslands used for domestic livestock are often the common property of several owners and are typically characterized by complex ecosystem dynamics. We account for both these aspects by modeling the problem as a differential game where each farmer maximizes profits, given the dynamics of livestock and grass interaction. We compare the first best outcome obtained when farmers cooperate with tha...

In cost sharing games, the existence and efficiency of pure Nash equilibria fundamentally depends on the method that is used to share the resources’ costs. We consider a general class of resource allocation problems in which a set of resources is used by a heterogeneous set of selfish users. The cost of a resource is a (non-decreasing) function of the set of its users. Under the assumption that...

Grid technologies aim at enabling a coordinated resource-sharing and problem-solving capabilities over local and wide area networks and span locations, organizations, machine architectures and software boundaries. The heterogeneity of involved resources and the need for interoperability among different grid middlewares require the sharing of a common information model. Abstractions of different...

SMT processors increase performance by executing instructions from several threads simultaneously. These threads use the processor’s resources better by sharing them, but, at the same time, threads are competing for these resources. The way critical resources are distributed among threads determines the final throughput and also the performance of each individual thread. Currently, the processo...

Many people are sharing digital resources through networks in order to facilitate, enhance or improve collaborative work. Information sharing is not only important to support collaborative work but it also represents the basis for design and implementation of solutions for typical design aspects of groupware applications, such as: floor control, group memory, shared objects replication and sess...
