Owing to advances in digital technology, emerging breakthrough solutions responding to market needs are becoming increasingly innovative and complex. Large amount of resources, competencies, skills, etc. are required to accomplish such solutions, usually beyond the capabilities and capacities of a single organization. The emergence of co-innovation networks as breeding environments for creation...

in today’s global economy, the fundamental attribute of competitiveness have been driven from pecuniary capital to knowledge capital so that knowledge is known as the unique strategic resource to acquire competitive advantage. therefore, businesses that efficiently utilize existing knowledge within their organizations are expected to gain comparative advantage over their competitors. this resea...

Learners and tutors in cooperative learning environments need a shared tool for preparing material, taking notes and exchanging thoughts synchronously. To this aim, we developed a Java tool, the Shared Multimedia Notebook, which supports shared user operations on static and time-based media objects. Cooperative tasks are supported by enabling collaborative interaction among users and offering p...

Cooperative applications require advanced transactional services that make the sharing and exchange of information as natural as possible while preserving a notion of consistency. Conventional transaction models that were based on the ACID properties do not meet the typical requirements of cooperative applications. The CoAct model [RKT95, WK96] is designed for supporting cooperative work in int...

Emerging cooperative MIMO communication is a promising technology in improving communication performance for wireless sensor networks. However, the security problems inherent to cooperative communications also arise. In this paper, we propose a cross-layer secured communication scheme for cooperative MIMO communication in wireless sensor networks to overcome the external and active compromised ...

In order to provide electronic service delivery, several activities involving different public agencies need to be related and carried out in coordinated manner, thus resulting in a cooperative process. Currently, e-Service technologies seems to offer the enabling infrastructure for supporting cooperative process enactment, even at inter-country level. In this position paper, we outline the arc...

CSCW(Computer-Supported Cooperative Work) and SPT (Software Process Technology) are two important, interrelated research areas. This paper investigates some key issues in CSCW from the SPT point of view. We present a classification and characterization of cooperative work mainly from the process point of view, propose a general process architecture supporting all kinds of cooperative work, and ...

This paper is directly focused on the design of middleware functions to support a distributed cooperative authoring environment on the World Wide Web. Using the advanced storage and access functions of the PIÑAS middleware, co-authors can produce fragmented and replicated documents in a structured, consistent and efficient way. However, despite it provides elaborated, concerted, secure and para...

This paper examines some of the issues arising from customer requirements concerning the management of end-to-end services and guaranteed end-to-end quality of service. The implications of supporting the desired management capabilities both horizontally (inter-domain cooperative management) and vertically (from the service to the network elements) are discussed using as examples work currently ...
