We study two types of two player, perfect information games with no chance moves, played on the edge set of the binomial random graph G(n, p). In each round of the (1 : q) Waiter-Client Hamiltonicity game, the first player, called Waiter, offers the second player, called Client, q + 1 edges of G(n, p) which have not been offered previously. Client then chooses one of these edges, which he claim...

One issue in client/server information systems is the storage of the relationships between clients and data used by these clients. In particular in scenarios that allow the caching of data on the client site, this information can be used in order to keep the global database consistent. Thus, if the data on the server are updated, it is possible to detect caches affected by the update. In a foll...

In this paper, we propose an efficient client-to-client streaming approach to cooperatively stream the video using chaining technique with unicast communication among the clients. This approach considers two major issues of VoD 1) Prefix caching scheme to accommodate more number of videos closer to client, so that the request-service delay for the user can be minimized. 2) Cooperative proxy and...

Waiter – Client and Client – Waiter games are two–player, perfect information games, with no chance moves, played on a finite set (board) with special subsets known as the winning sets. Each round of the biased (1 : q) Waiter–Client game begins with Waiter offering q + 1 previously unclaimed elements of the board to Client, who claims one and leaves the remaining q elements to be claimed by Wai...

For a finite set X, a family of sets F ⊆ 2X and a positive integer q, we consider two types of two player, perfect information games with no chance moves. In each round of the (1 : q) Waiter-Client game (X,F), the first player, called Waiter, offers the second player, called Client, q + 1 elements of the board X which have not been offered previously. Client then chooses one of these elements w...

the main purpose of this paper is survy of factors associated with reliance of external auditors on entenal adutors work , reliance on internal auditors work has significant influence on cost saving and obtaining more services to client with the same cost. optimal utilization of internal audit work can improve both the efficiency and the effectiveness of external audits and can enhance the valu...

Applications and components are exposed to different security threats in different environments. We want to tailor the defence of these applications and components to the particular threats faced by them in the target execution environment. Ideally we want to be able to adapt applications and components as they are downloaded into the execution environment. However, one problem with this approa...

Insurance companies are among the service organizations, which maintain close relationships with their clients by providing insurance services. Clients are the most important resource for service companies. And profitability of insurance companies undoubtedly hinges on clear analysis of client satisfaction and improved productivity of service providers. An important factor of client satisfactio...

Security problems in collaborative work between multiple agencies are less well understood than those in the business and defence worlds. We develop a perspective for policies and models that is task-based on a need-toknow basis. These policies are represented by two protocols, the first CTCP (Collaboration Task-based Creation Protocol) dealing with negotiation, decision and agreement between t...
