چکیده

Social storage systems [1], [2], [3] are becoming increasingly popular compared to the existing data backup systems like local, centralized and P2P systems. An endogenously built symmetric social storage model and its aspects like the utility of each agent, bilateral stability, contentment, and efficiency have been extensively discussed in [4]. We include heterogeneity in this model by using the concept of Social Range Matrix from [5]. Now, each agent is concerned about its perceived utility, which is a linear combination of its utility as well as others utilities (depending upon whether the pair are friends, enemies or do not care about each other). We derive conditions when two agents may want to add or delete a link, and provide an algorithm that checks if a bilaterally stable network is possible or not. Finally, we take some special Social Range Matrices and prove that under certain conditions on network parameters, a bilaterally stable network is unique.

In search of stars: Network formation among heterogeneous agents

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by introducing agents with lower linking costs or higher benefits to others. Furthermore, agents’ types may be common knowledge or private information. In all treatments, ...

Burt: The Backup and Recovery Tool

Burt is a freely distributed parallel network backup system written at the University of Wisconsin, Madison. It is designed to backup large heterogeneous networks. It uses the Tcl scripting language and standard backup programs like dump(1) and GNUTar to enable backups of a wide variety of data sources, including UNIX and Windows NT workstations, AFS based storage, and others. It also uses Tcl ...

Adaptive Protection Based on Intelligent Distribution Networks with the Help of Network Factorization in the Presence of Distributed Generation Resources

Factorizing a system is one of the best ways to make a system intelligent. Factorizing the protection system, providing the right connecting agents, and transmitting the information faster and more reliably can improve the performance of a protection system and maintain system reliability against distributed generation resources. This study presents a new method for coordinating network protect...

A Novel Combinatorial Approach to Discrete Fracture Network Modeling in Heterogeneous Media

Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness of data have incapacitated conventional deterministic methods in fracture network modelin...
