An autonomic detection and protection system for denial of service attack
(
ACTA Press
, 2012 , Conference Paper)
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 ...
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 ...
Practical and secure outsourcing of matrix computations to the cloud
(
IEEE
, 2013 , Conference Paper)
Cloud computing enables a cost effective outsourcing of storage and resource-intensive computations. Secure outsourcing of data and computation is challenging in this emerging computing model. In particular, outsourcing ...
Towards model-based management of database fragmentation
(
USENIX Association
, 2013 , Conference Paper)
The performance of a database can significantly deteriorate due to the fragmentation of data/index files. Manual database defragmentation and performance optimization remain time consuming and even infeasible as it requires ...
The Attitudes of Qatari Nationals and White-Collar Resident Workers Towards the New Traffic Law in Qatar
(2012 , Conference Paper)
In 2007 the government of Qatar enacted a new traffic law with the objectives of improving the traffic flow and reducing the road traffic-related death and accident rates in the country through policy interventions, mass ...
An efficient component map generation method for prediction of gas turbine performance
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
Improving efficiency, reliability and availability of gas turbines have become more than ever one of the main areas of interest in gas turbine research. This is mainly due to the stringent environmental regulations that ...
Fault-tolerant control of five-phase current source inverter for medium-voltage drives
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Multiphase Machines offer a promising solution to many practical challenges due to their advantages over the three phase counterparts, as fault-tolerant capability and lower torque ripple magnitude. Among different multiphase ...
An LP model for optimizing a supply chain management system for steel company
(
Newswood Limited
, 2014 , Conference Paper)
In this research, we have developed a linear programming formulation to describe Qatar steel manufacturing supply chain from suppliers to consumers. The purpose of the model is to provide answers regarding the optimal ...
A framework for optimizing the supply chain performance of a steel producer
(2013 , Conference Paper)
Supply Chain Management (SCM) is focused on developing, optimizing, and operating efficient supply chains. Efficient supply chains are characterized by cost effective decisions, lean flow and structure, high degree of ...
An analytic network process condition assessment model for sewer pipelines
(
Civil-Comp Press
, 2015 , Conference Paper)
As sewer pipelines age, the need for their upgrading, maintaining, and repairing arises. Simultaneously, inadequate sewer pipelines might lead to catastrophic failures. Thus, decision makers must have a detailed knowledge ...
