Addressing security compatibility for multi-tenant cloud services
( Inderscience Publishers , 2013 , Article)This paper addresses the issue of compatibility checking between the security requirements of service clients and the security assurances provided by multi-tenant cloud services. To allow early detection of security ... -
ARCS-based tactics to improve students' motivation in computer programming course
( IEEE , 2015 , Conference Paper)Most students find computer programming difficult subject, which frustrates them and affects their performance. In this paper, we present our experience of using ARCS model to improve students' motivation when learning ... -
Cognition-based adaptive programming tutoring system
( IEEE , 2016 , Conference Paper)The most important potential of E-learning system is the ability to adapt based on learner's status in order to support personalized learning. However, this requires using specific learner's parameters as factors to control ... -
Mobile Application for Diabetes Control in Qatar
( IEEE , 2012 , Article)In Qatar, the prevalence of diabetes is significantly high, therefore a lot of efforts have been made to control this epidemic. This paper presents a mobile application aims to assist diabetic people in Qatar to manage ... -
Modeling security importance and preferences of software services
( IEEE , 2012 , Conference Paper)This paper proposes a modeling framework on how to specify security preferences and importance of software services, and compute a quantifiable value. Our approach advocates for an automatic calculation of the results of ... -

Reasoning about Policies in Security-Aware Service Discovery Using Answer Set Programming
( World Scientific Publishing Co. Pte Ltd , 2016 , Article)In order to enable a secure interaction between dynamically discovered software services and the client's application in a cooperative information system such as service oriented system, one of the pre-requisites is the ... -
Reasoning about security policies of services using answer set programming
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, we propose a formal framework for checking the consistency of security policies of services using Answer Set Programming (ASP). We illustrate that the formalisation of security policies of the service providers ... -
Security oriented service composition: A framework
( IEEE , 2012 , Conference Paper)This paper argues that in order to address the challenges of security compatibility checking between the client's software and the service software in a service oriented software environment, the followings have to be ... -
