Two novel expert dynamic buffer tuners/controllers, namely, the neural network controller (NNC) and the fuzzy logic controller (FLC) are proposed in this paper. They use soft computing techniques to eliminate buffer overflow at the user/server level. As a result they help shorten the end-to-end service roundtrip time (RTT) of the logical Internet(More)
The novel real-time traffic pattern detector (RTPD) proposed identifies the Internet traffic pattern on the fly. Firstly it determines if a time series aggregate is stationary. Secondly it confirms if the aggregate exhibits short-range dependence (SRD) or long-range dependence (LRD). Thirdly it detects if the smooth system operation has suddenly become(More)
An Internet-based distributed manufacturing system usually consists of a network/grid of autonomous centers that collaborate together. Each center may receive world-wide customer orders and collaborates with other friendly manufacturers, sub-contractors, agents, and suppliers to maximize the sales and quality of the goods. The centers together strike a(More)
Ambient intelligence is an important element for the success of digital ecosystems which usually are made up of many collaborating distributed nodes. The operations of these nodes affect one another as chain reactions. When one node had failed, it could bring down the whole ecosystem. Dynamic buffer tuning is an ambience-intelligent mechanism because it has(More)
Frequent patterns mining is the focused research topic in association rule analysis. Most of the previous studies adopt Apriori-like algorithms or lattice-theoretic approaches which generate-and-test candidates. However, there are extremely invalidated candidate generations in the exponential search space. In this paper, we systematically explore the search(More)

A method of sensitivity analysis is developed that allows the recomputation of a new schedule for not too large variations in system conditions such as loads or constraints values. This allows both for less frequent re-solution of the total optimal power flow problem as well as quick calculation of new schedules if the system is in an alert state. The(More)
This paper describes the conceptual design of OBJECTSIM. OBJECTSIM represents a new flexible and generic approach to modelling the performance of parallel and distributed systems. Performance measures of interest include overall execution speed, numbers of secondary memory accesses and network reconfiguration and routing activity. Using distributed(More)
The agents or entities frequently require intelligence in the form of knowledge based systems(KBS) to support many of their functions. In this Paper we discuss how these KBSs are conceptual are conceptually modeled as a first step towards their development. In particular, we show to effectively model all the different knowledge constructs using an extended(More)
The Internet follows the power law. For this reason its traffic pattern takes many forms, which change without warning. For example it may change suddenly from LRD (long-range dependence) such as heavy-tailed or self-similar to SRD (short-range dependence) such as Poisson or multifractal. This makes it difficult to run time-critical pervasive applications(More)
Telemedicine means administering medicine over the mobile Internet. This may involve mobile clinics (MC) which, while moving from one geographical location to another to treat patients, always maintain contact with the distant medical centre for backup in the patient treatment process. Usually patients in different geographical locations would have varied(More)
