A utility-based adaptivity model for mobile applications
(2007)
Mobile environments are characterized by resource fluctuations and limitations, and variations in user preferences. Therefore mobile applications need to be adaptive to retain usability, usefulness and reliability. In our ...
IWIM semantics via fibred automata
(2002)
Coordination programming helps to separate concerns in the programming of the coordination activities in complex applications software. It separates the development, verification, maintenance, and reuse of the coordination ...
The KGP model of agency for Global Computing: Computational model and prototype implementation
(2005)
We present the computational counterpart of the KGP (Knowledge, Goals, Plan) declarative model of agency for Global Computing. In this context, a computational entity is seen as an agent developed using Computational Logic ...
Crafting the mind of prosocs agents
(2006)
PROSOCS agents are software agents that are built according to the KGP model of agency. KGP is used as a model for the mind of the agent, so that the agent can act autonomously using a collection of logic theories, providing ...
Extended semantics and optimization algorithms for CP-networks
(2004)
Preference elicitation is a serious bottleneck in many decision support applications and agent specification tasks. Ceteris paribus (CP)-nets were designed to make the process of preference elicitation simpler and more ...
Efficient bufferless packet switching on trees and leveled networks
(2007)
In bufferless networks the packets cannot be buffered while they are in transit
Analysis of fluctuation-induced firing in the presence of inhibition
(IEEE, 2000)
This paper examines the computational role of inhibition as it moves towards balancing concurrent excitation using the biologically-inspired Temporal Noisy-Leaky Integrator (TNLI) neuron model. The TNLI incorporates ...
Testing the predictability of the Cyprus Stock Exchange: The case of an emerging market
(IEEE, 2000)
A systematic investigation of the effect of different neural network architecture alternatives for predicting the future course of stock prices in the Cyprus Stock Exchange (CSE) market is conducted. This market exhibited ...
Implementing the MPEG-21 adaptation quality of service in dynamic environments
(2006)
MPEG-21 embeds the AQoS schema tool which describes and associates conceptually major utilities required during the adaptation process, for example, adaptation operators, constraints and qualities. Defining an AQoS model, ...
Adaptive nonlinear congestion controller for a differentiated-services framework
(2005)
The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In ...
