Cooperative work on shared information requires different kind of computing system support to coordinate the work of multiple users, to establish mutual awareness and to ensure consistency. These issues are currently tackled separately in various loosely related areas, like workflow systems, groupware, and advanced transactional models. We present a transactional model that provides a core func...

With the identification of cooperative vehicular communication as an encouraging solution to real time traffic management problems, there has been efforts in evaluating more efficient communication technologies and applications. Field operational tests (FOTs) exist and provide precise evaluation tools but they have limitations. It is impractical to imagine evaluation of large scale city like sc...

Cooperative work on shared information requires different kinds of computing system support to coordinate the work of multiple users, to establish mutual awareness among users, and to ensure the consistency of user results. These issues are currently tackled separately in various loosely related areas, such as workflow systems, groupware, and advanced transactional models. In the TRANSCOOP proj...

In the CAD, CAM. and Robotics environment the on-line construction and manipulation of data ob’ects is very often done at dedicated workstations rather than at h ost systems. As the storage space of workstations is usually not that large and as large designs are also not performed by a single designer but by a group of designers, in general, one would like to use host database systems as centra...

in this research the cooperative sector's law has been analyzed under the general headings cooperative as an economic sector, cooperative's and cooperatives :union:’s nature, and damages of the acts to the law and the normal function of cooperatives and at the end it has been analytically concluded that regarding the stated structural and legal deficiencies while keeping the cooperati...

Practitioner's Abstract While not ignoring risk, agricultural cooperatives tend to accommodate risk through the holding of internal capital reserves rather than engage in active risk management. A lack of information regarding the ...

This paper presents a methodological framework for the design of intercompany cooperation systems in the field of an extended enterprise. This framework relies on cooperation engineering enabling capitalization of knowledge in cooperative activities.

Dynamic memory management is a known performance bottleneck of Java applications. The problem arises out of the Java memory model in which all objects (non-primitive type instances) are allocated on the heap and reclaimed by garbage collector when they are no longer needed. This paper presents a simple and fast algorithm for inference of object lifetimes. Given the analysis results, a Java comp...
