The Virtual Secretary (ViSe) is a kind of intelligent agent that could assist its user in major secretarial work. Users give the orders of what to do, while agents figure out how to do and carry out the tasks. This paper presents the ViSe agents in two aspects: (1) construct individual agent on three intelligence levels: knowledge-base level, learning level and cooperation level; and (2) to mod...

In this letter, we propose a novel precoding scheme for base station (BS) cooperation in downlink cellular networks that allow overlapped clusters. The proposed precoding scheme is designed to mitigate the overlapping-BS interference by maximizing the so-called clustered virtual signal-to-interferenceplus-noise ratio (SINR). Simulations show that with the proposed scheme, overlapped clustering ...

Global Address Space (GAS) programming models enable a convenient, shared-memory style addressing model. Typically this is realized through one-sided operations that can enable asynchronous communication and data movement. With the size of petascale systems reaching 10,000s of nodes and 100,000s of cores, the underlying runtime systems face critical challenges in (1) scalably managing resources...

Cooperation is intrinsic to the human ability to work together toward common goals, and depends on sensing and reacting to dynamically changing relationships between coacting partners. Using functional magnetic resonance imaging (fMRI) and a paradigm in which an adaptive pacing signal simulates a virtual partner, we examined the neural substrates underlying dynamic joint action. A single parame...

This paper describes JuNI++, a C++ native interface for interpreted Java Virtual Machines. While JuNI++ was initially designed in order to integrate the RTSJ implementation jRate with Juice, a virtual machine for small footprint environments, its engineering and performance advantages outlived the initial goal. The main contribution of this paper is to show how a C++ based native interface can ...

In this paper we discuss the application of federation techniques for virtual enterprises. Virtual enterprises are a kind of cooperation between independent companies with a common goal. Requirements to an integrating information system are presented. We describe the integration of local information systems by a federated database system (FDBS) and discuss how an FDBS can meet the requirements....

The virtual organizations paradigm combined with adequate tools to support the cooperation of social care assistants, health care professionals, elderly people, and their relatives, constituting a “virtual community”, represent a promising approach to reduce the overwhelming care provision costs and to increase their quality. An architecture for a flexible platform based on adaptive mobile agen...

The MOVE-project aims at a general methodology and a reusable software framework to support the coordination and cooperation in virtual enterprises and to optimise individual business processes and required resources. This article examines the requirements for computer supported planning in virtual enterprises with a focus on optimisation of the partly contradictionary objectives satisfying cus...

In this study, a Virtual Learning System that integrates Virtual Classroom and Virtual Laboratory services is presented. The Virtual Classroom represents an interface between the students and a virtual professor and provides personalized learning materials to the users. The Virtual Laboratory offers a possibility to the attendees to share different resources at once and work with them as if the...
