Semantics-based approach for dynamic evolution of trust negotiation protocols in cloud collaboration
(
Springer Verlag
, 2014 , Conference Paper)
Many techniques for addressing trust negotiation issues is little concerned with managing the dynamic evolution of trust negotiation protocols (policies), particularly in cases where there exist ongoing negotiations when ...
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 ...
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 ...
Cluster validity index based on n-sphere
(
IEEE
, 2014 , Conference Paper)
In this paper, we propose a new cluster validity index (CVI) based on geometrical shape. Classic CVIs are based on a combination of separation and compactness measures and may include a measure of overlap between clusters. ...
Computational Simulation Of Organic Rankine Cycle Retrofitted To Petroleum Well
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Geothermal refers to existing heat energy in deep rock and sedimentary basins. Unlike other types of renewable energy resources, geothermal energy provides a stable source of energy as it can be exploited regardless of ...
Numerical simulation of using combined active and passive stall control techniques in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This study presents a numerical simulation of stall control by using the casing treatment method which represents the passive control technique and also by using the air injection method which represents the active control ...
Numerical investigation of rotating stall characteristics and active stall control in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This paper focuses on providing better view for the understanding of rotating stall phenomenon in centrifugal compressors by using numerical simulations and presents a study of the role of air injection method in delaying ...
Numerical simulation and control of rotating stall in a transonic centrifugal compressor
(
Web Portal ASME (American Society of Mechanical Engineers)
, 2014 , Conference Paper)
This study presents a numerical simulation of precursors and characteristics of rotating stall in a centrifugal compressor with vaned diffuser. The aim is to further understand the causes of stall inception, characteristics ...
