Software interfaces: On the impact of interface design anomalies
( IEEE , 2013 , Conference)Interfaces are recognized as an important mechanism to define contracts governing interactions between semi-independent software modules. Well-designed interfaces significantly reduce software complexity and ease maintainability ... -
Mobile crowdsourced sensors selection for journey services
( Springer Verlag , 2018 , Conference)We propose a mobile crowdsourced sensors selection approach to improve the journey planning service especially in areas where no wireless or vehicular sensors are available. We develop a location estimation model of journey ... -
Online cost optimization algorithms for tiered cloud storage services
( Elsevier , 2020 , Article)The new generation multi-tiered cloud storage services offer various tiers, such as hot and cool tiers, which are characterized by differentiated Quality of Service (QoS) (i.e., access latency, availability and throughput) ... -
Towards automated hazard analysis for CPS security with application to CSTR system
( Elsevier , 2022 , Article)Hazard analysis to identify risks due to cyber attacks is crucial to ensure cyber-physical systems' safety and correct their behavior. This study proposes a framework to analyze cyber-physical systems (CPS) risks using ... -
Web Application Resource Requirements Estimation Based on the Workload Latent Features

Policy-based customisation and corrective adaptation of composite web services
( Inderscience Publishers , 2011 , Article)Due to the typical long-running character of business processes, it is often desirable to be able to change a running process to respond to changes of business requirements and company policies. However, current process ... -
LingoSnacks: M-Learning platform for language learning
( IEEE , 2012 , Conference)This paper reports the experience of designing and developing a multimedia m-Learning platform (named LingoSnacks) for interactive learning of Arabic spelling and vocabulary. It uses interactive game-like delivery methods ... -
A model-based approach to self-protection in computing system
( Association for Computing Machinery, Inc , 2013 , Conference)This paper introduces a model-based autonomic security management (ASM) approach to estimate, detect and identify security attacks along with planning a sequence of actions to effectively protect the networked computing ... -
An autonomic detection and protection system for denial of service attack
( ACTA Press , 2012 , Conference)This paper introduces a self-protection structure for computing system. The proposed structure aims to detect, classify and protect against DoS attacks. This architecture utilizes a model-based decision approach that ... -
Applying and evaluating architectural patterns on a stock trading case study
( IEEE , 2012 , Conference)Teaching architectural and design patterns is a difficult task and not easy to understand by the students as patterns are expressed at a higher abstraction level than programming language constructs or graphical UML ... -
A finite context intrusion prediction model for cloud systems with a probabilistic suffix tree
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)The success of the cloud computing paradigm depends on how effectively the cloud infrastructures will be able to instantiate and dynamically maintain computing platforms that meet Quality of Service (QoS) requirements. ... -
Probabilistic qualitative preference matching in long-term IaaS composition
( Springer Verlag , 2017 , Conference)We propose a qualitative similarity measure approach to select an optimal set of probabilistic Infrastructure-as-a-Service (IaaS) requests according to the provider's probabilistic preferences over a long-term period. The ... -
