Computational models and heuristic methods for Grid scheduling problems
Fatos Xhafa,Ajith Abraham +1 more
TL;DR: The paper reveals the complexity of the scheduling problem in Computational Grids when compared to scheduling in classical parallel and distributed systems and shows the usefulness of heuristic and meta-heuristic approaches for the design of efficient Grid schedulers.
Proceedings ArticleDOI
A Review on Massive E-Learning (MOOC) Design, Delivery and Assessment
TL;DR: The state of the art on MOOCs is analyzed, a framework that includes the use of software agents with the aim to improve and personalize management, delivery, efficiency and evaluation of massive online courses on an individual level basis is proposed.
Journal ArticleDOI
Intelligent services for Big Data science
Ciprian Dobre,Fatos Xhafa +1 more
TL;DR: CAPIM is a platform designed to automate the process of collecting and aggregating context information on a large scale that provides support for intelligent Smart City applications, for actively and autonomously adaptation and smart provision of services and content, using the advantages of contextual information.
Journal Article
Genetic algorithm based schedulers for grid computing systems
TL;DR: The extensive experimental study showed that the GA-based schedulers outperform existing GA implementations in the literature for the problem and also revealed their efficiency when makespan and flowtime are minimized either in a hierarchical or a simultaneous optimization mode.
Journal ArticleDOI
L-EncDB: A lightweight framework for privacy-preserving data queries in cloud computing
TL;DR: A new format-preserving encryption (FPE) scheme is constructed in this paper, which can be used to encrypt all types of character strings stored in database and is highly efficient and provably secure under existing security model.
