In peer-to-peer (P2P) applications, peers make an agreement on one opinion. Agreement procedures have to be so flexible that persons can change their opinions. We discuss a flexible agreement protocol of multiple peers by taking advantage of human behaviors in a fully unstructured P2P network. There are forward, backward, mining, and observation strategies(More)
The trustworthiness of peers is very important for safe communication in P2P system. In this paper, we propose a fuzzy-based reliability system for P2P Communications in JXTA-Overlay. We use three input parameters: Number of Interactions (NOI), Amount of Data Exchanged (ADE), and Reputation (R) and the output is Peer Reliability (PR). We evaluate the(More)
In this paper, we provide an evaluation method for both: the quality aspect of corporations (marketable quality) and the profitability. We define the corporation rate of operation and profitability. Based on these definitions, we present a model to identify the profitability function considering the rate of operation at the break-even point. This function(More)
In information systems, processes have to be scheduled to share a limited amount of resource objects like memory and CPU with other processes. In database systems, conflicting access requests from multiple transactions have to be serialized. There are various ways to order multiple conflicting access requests like FIFO and timestamp ordering (TO) schemes.(More)
The mental image directed semantic theory (MIDST) has proposed a formal language L/sub md/ employed for many-sorted predicate logic and whose semantics is given based on an omnisensual mental image model so called "Loci in Attribute Spaces". This language can be used for intermediate knowledge representation of multimedia contents and has been applied to an(More)
The main objective of this paper is to provide an evaluation method for both: the quality aspect of corporations (marketable quality) and the profitability. First, we define the corporation rate of operation and profitability. Based on these definitions, we present a model to identify the profitability function considering the rate of operation at the(More)
